This paper analyzes long and short term relationships between the components of the public debt in Lebanon by applying the cointegration analysis of monthly time series, from January 1994 to May 2014 (245 observations), according to Johansen’s procedure. The Gross Local Currency Debt(GLCD) and the Foreign Currency Debt (FCD) are not cointegrated and are modeled by near-VAR (39) revealing bidirectional causality between them. The forecasts for May 2015 are respectively USD 40.16 billion and USD 27.375 billion. These results allow us to estimate 0.28% and 0.36% as monthly growth rates from May 2014 until May 2015 for GLCD and FCD respectively. The treasury bills at short and long terms (TBST, TBLT) are cointegrated (a constant in the cointegrating relationship). The same applies to treasury bills at 12, 6 and 3 months (TB12, TB6, TB3). For the systems (TBST, TBLT) and (TB12, TB6, TB3), the available forecasts for May 2015 are respectively in USD billion (0.766, 39.568) and (0.734, 0.544, 0.153). Economic growth in Lebanon is affected by turmoil in Arab countries. The growth in the gross domestic product (GDP) retreated, while the gross public debt (GPD) continued to rise. It is true that Lebanon has large financial reserves due to the deposits of its citizens in local commercial banks, also Lebanon gained the confidence of international financial institutions due to its loyalty in paying foreign and domestic debts. Howeverthe Lebanese state must establish a strategic plan based on political stability that will certainly increase economic growth, as well as on oil exploration on the Lebanese coast. Perhaps, this political behavior could allow the control of public debt and enable Lebanon in gradually reducing it
In this brief, Elena Jarocinska summarizes the main thrust of Russian federal fiscal institutions and discusses their specific features. She describes the evolution of federal fiscal regulations since the establishment of the Russian federal state. As a conclusion, she offers the following policy recommendations: tax autonomy of subnational governments which is currently very limited should be increased; federal aid should be further formalized and made more transparent; regulations should not be changed from year to year to provide for a more stable environment; and subnational interests should be better protected at the institutional level.

Azerbaijan’s current fiscal stance is quite strong; however, this stability is completely based on oil-related revenues. In the meantime, the situation with alternative sources of fiscal revenues is uncertain. A large part of fiscal management is built on opacity and an assessment of budget spending efficiency has never been done. It is likely that Azerbaijan will only be able to maintain its fiscal stability through the next ten years or so, i.e. until the end of the active oil-extraction period. In the more distant future, a substantial fiscal correction will be necessary.

In this paper the concept of total gross seigniorage is used to analyze sources of revenues of National Bank of Georgia (NBG) and their distribution in the period 1996-1999. A comprehensive framework for measuring total seigniorage and its main components is presented and estimates of seigniorage revenues (sources and uses) are computed and analyzed. It is shown that in the considered period fiscal revenues from NBG have not been extensively financed by the money supply (consequently, cannot be estimated by the monetary seigniorage), but have been mostly covered by the reduction of the non government debt hold by central bank. Since the stock of international and private domestic assets hold by National Bank of Georgia is limited, in long run NBG cannot rely on it. The only way how, in the future, NBG can finance large deficits of the state budget is to use monetary seigniorage. This, however, will have to be accompanied by significant growth of monetary base and will cause a danger of large inflation.

The study area lies within latitudes 8°00' – 9°00'N and longitudes 11°30' – 12°30'E. Analysis of remote sensing imageries of part of the Upper Benue Trough of Nigeria was carried out on a scale of 1:100,000. The aim of this study includes the structural interpretation of the remote sensing data and the identification of the lineament and drainage patterns associated with the area to infer the influence of such structures on the economic potential of the basin. Results of the structural analysis revealed numerous lineaments. Trend analysis of the lineaments plotted on a rose diagram using the strikes and lengths of the entire lineaments revealed structural trends predominating in the NE-SW direction. The absence of visible lineaments in parts of the area may not indicate absence of geological structures. Some of these lineaments were found on some drainages showing that the drainages in those areas are structurally and tectonically controlled. The areas where the lineaments cross each other are indicative of groundwater availability and there correspond to regions of mean topographic height of about 900m

Detection and Rectification of Distorted Palm Print Imagestheijes
Distorted or obscure Palm Print Images is one of the major reasons for false non-match. Due to false nonmatch this problem affects all Palm Print recognition applications this problem mainly affects in negative recognition applications, many users purposely distorted their palm print avoid identification. here in this paper novel algorithms is to used to detect and rectify sin distorted based on a single palm print image. Here we don’t use novel algorithm directly rather than this novel algorithm Gaussian blur algorithm is used for distortion of palm print images. Palm Prints are used as the feature vector and a SVM classifier is used to classify the palm print images. Finally the rectification of distorted images will be implemented. Where the input is a distorted palm print and the output is the distortion field. To detect this distorted or obscure palm print image problem a database of various distorted reference palm prints are used. Input palm print is found in the reference database and the respective distortion field is used to convert the input palm print into a normal form.
Cables are invaluable structural elements. They have been used in guyed towers, bridges marine vehicles, offshore structures, transmission lines and tensioning applications etc. Briefly, cables are necessary elements for long spans. As known, cables are tension elements; they cannot carry any compression load due to its unique geometry. This tangential convoluted geometry makes them hard to analyze. Engineers solve cables assuming them as linear elements even now, because cables cannot be solved by classical finite element methods. Having almost zero bending rigidity makes it vulnerable to drastic vertical movements. Hence, engineers either define a bending rigidity or apply a checker for drastic movements in each nonlinear iteration to solve cable by classical FEM. Therefore, engineers propose a different iterative finite element method to solve cables more stabilized way. In this research, a 3D static solution method is presented for a cable supported at its ends. This method first makes the cable determinant by releasing one cusp of the cable. Then playing with the reaction at the other cusp changes the position of the released cusp. Thus, one can determine the correct reactions at the first cusp, which makes the second cusp position same with the released support’s. Cable equilibrium equations and stiffness matrix is derived accordingly and some sample cables are solved.

Application of Foamy Mineral Oil Flow under Solution Gas Drive toa Field Crud...theijes
Heavy oil Flow in the form of foamy oil under solution gas drive is widely observed in many Canadian reservoirs. Despite the importance of such phenomenon, complexity involved in foamy oil flow in porous media is not well understood. Series of numerical simulations were performed to model experiments that were carried out in a two meter long Sand pack to investigate the conditions required to increase oil production under solution gas drive mechanism. Through these experiments the solution gas drive performance at different depletion rates were analyzed. Creation of foamy heavy oil is thought to be responsible for higher recovery factors compared to what is expected from the conventional solution gas drive theory. However, the complex nature of foamy oil and different transport parameters are yet to be understood.The results of this study can be used to numerically model foamy-oil mechanism in heavy oil reservoirs. Furthermore, the results can be applied for reservoir production optimization as well as management. A new model has been developed using commercial numerical simulator, computer modeling group, (CMG-STARSTM). By using the experimental data, different experimental production histories have been matched. Effect of different parameters such as fluid and reservoir properties and depletion rate on foamy oil recovery have been evaluated. The results reveal that despite many difficulties, foamy oil flow through porous media can be numerically modeled. However these models will strongly depend on a good understanding of many different parameters including rock-fluid interaction, as well as the depletion rates. Given the complex nature of such systems, this numerical model can be used to simulate and predict the oil and gas production from heavy oil reservoirs under foamy oil conditions

Lebanon is socially and economically a liberal country, where service sector of the economy is most developed. The country is considered a “piece of investment and touristic heaven” for neighboring Arabian countries, mainly because of its natural and touristic capital, its developed banking sectors, its hybrid mix of Eastern and Western cultures and its geographic location serving as a transit line for trade between Europe and the Middle East.
In the article the socioeconomic history of Lebanon was discussed by four phases:
1. The period of first independence in 1943-1975
2. The civil war of 1975-1990.
3. Post-war recovery period from 1990-2000
4. Current socioeconomic and political situation 2000-Present

Marwan Kheireddine | Economic reforms in Lebanon face a complex set of challenges and opportunities in the context of a globalized world. Lebanon has been grappling with economic and political instability for many years, and addressing these issues requires a comprehensive approach. According to Marwan Kheireddine, economic reforms in a globalized world are essential for countries to adapt and thrive in the increasingly interconnected and competitive global economy. “In Lebanon’s case, these reforms aim to enhance economic efficiency, foster growth, attract investment, and address various challenges”, he adds.
This paper investigates the barriers to innovation perceived by Polish manufacturing firms. It refers to the heterogeneity of innovation active firms. We introduce a taxonomy of innovative firms based on the frequency with which they introduce commercialised innovations using data from both CIS4 (for 2002-2004) and CIS5 (2004-2006). Two groups of innovation-active firms are distinguished: those which introduced innovation in both periods covered by both CIS (which we call persistent innovators) and those which introduced innovation either in CIS4 or CIS5 (which we call occasional innovators). We use a four step analysis covering binary correlations, Principal Component Analysis, probit model and correlations of disturbances. Two types of explanatory variables describing firms’ characteristics and innovation inputs used are considered. The paper shows that there are considerable differences in sensitivities to the perception of innovation barriers and in complementarities among barriers between persistent and occasional innovators. In the case of occasional innovators, a kind of innovation barrier chain is observed. This has an impact on differences in the frequency of innovation activities between the two groups of innovators and results in a diversification of innovators.

This study empirically investigates the impact of human development on bank development in WAEMU countries. Over the period 1990 to 2014, empirical results have shown a positive relationship between banking development and human development. Credit to the private sector and the size of the economic system have a positive and significant impact on human development, but this impact remains small. Moreover, the growth rate of GDP per capita and the level of inflation have a positive impact on human development.
In this report published in September 2019, we present a legal and technical understanding of the general budget in Lebanon. We discuss the general budget, its components, its method of preparation, its main principles, and provide definitions to basic economic terms necessary to understand the public budget.
In addition to comparing the 2017 draft budget with the actual disbursements of the administrations that provided us with their financial statements, we analyze the 33 financial statements we acquired. We found it difficult to provide a comprehensive comparative study in terms of disbursements, however, because each administration has its own way of tabulating, identifying functions, and detailing disbursements (not identical to those published in the General Budget Project). In addition, many of the administrations that responded to us do not make any collection in favor of the treasury of the state, thus they only provided us with their disbursements without their collections.

Given the fact that monetary policy implemented until now does not apply to this new way of monetary policy, due to the lack of effectiveness with the ordinary instruments, then it must convince the Parliament that the reduction of the budget deficit should not be a priority within a political mandate. Trying to adjustment and deficit reduction within a mandate might be a good idea as long as the fluctuations of liquidity in the economy will not occur or will be with periphery influence.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

--------------------------------------------------------ABSTRACT-----------------------------------------------------------
This paper analyzes long and short term relationships between the components of the public debt in Lebanon by
applying the cointegration analysis of monthly time series, from January 1994 to May 2014 (245 observations),
according to Johansen’s procedure. The Gross Local Currency Debt(GLCD) and the Foreign Currency Debt
(FCD) are not cointegrated and are modeled by near-VAR (39) revealing bidirectional causality between them.
The forecasts for May 2015 are respectively USD 40.16 billion and USD 27.375 billion. These results allow us
to estimate 0.28% and 0.36% as monthly growth rates from May 2014 until May 2015 for GLCD and FCD
respectively. The treasury bills at short and long terms (TBST, TBLT) are cointegrated (a constant in the
cointegrating relationship). The same applies to treasury bills at 12, 6 and 3 months (TB12, TB6, TB3). For the
systems (TBST, TBLT) and (TB12, TB6, TB3), the available forecasts for May 2015 are respectively in USD
billion (0.766, 39.568) and (0.734, 0.544, 0.153).

reserves due to the deposits of its citizens in local commercial banks, also Lebanon gained the confidence of
international financial institutions due to its loyalty in paying foreign and domestic debts. Howeverthe Lebanese
state must establish a strategic plan based on political stability that will certainly increase economic growth, as
well as on oil exploration on the Lebanese coast. Perhaps, this political behavior could allow the control of
public debt and enable Lebanon in gradually reducing it.

I. INTRODUCTION
When public finances are weak and public debts are accumulated, doubts about the ability of the state to bear
financial cost can cause unsustainable debts. The solvency of a state reflects its ability to meet its obligations
according to its debts. Political debates to keep public debt under control abound, and the sustainability of public
finances is one of the most widely discussed topics in economics these days. The question is how to treat a
state’s solvency crisis. Indeed, if the foreign debt becomes excessive then non-resident lenders will stop
providing new loans. Consequently, the state will not be able to finance its foreign deficit and renew its foreign
debt, which leads to a serious crisis. However, if domestic saving is significant then the state could appeal to the
domestic debt to finance the public deficit. In the literature of public debt, we report the GPD to GDP ratio (in
some cases the Net Total Public Debt NTPD is used; it represents the difference between GPD and Public
Sector Deposits PSD). In some countries, the debt level has reached alarming levels: for example, in 2002, this
ratio reached 178% in Lebanon (≅ 146 % in 2013), and 149% in Argentina. While, Turkey, Brazil, India and
the Philippines showed lower percentages (89%, 78%, 77% and 77% respectively) (Bachellerie&Couillault
2005). Hence, the national benefit is to approve a long term stabilization of the debt to GDP ratio. In 2014, the
GPD to GDP ratio in the euro area EU-28 ranged from a low of 6% (Estonia) to a maximum of 177.1%
(Greece). And between 2011 and 2014 its average increased from 80.9 % to 86.8%.
In Lebanon, during the period 1994-2011, the coefficient multipliers of GDP and the gross public debt are 4.18
and 7.69 respectively, thus the debt grew faster than GDP and almost doubled (7.69/4.18 ≅ 1.84). The public
debt of a state is sustainable if the adopted fiscal policy could be maintained without excessive adjustment in the
future. The sustainability of a debt requires that (1) the creditors have a positive assessment of the state’s ability
to repay its debt in the long term, and (2) the state is able to refinance its debts at maturity. These elements are
largely based on the confidence of creditors and the credibility of the authorities.
The Lebanese state must seek sources to finance its public expenditures. The best known way is to use taxes or
loans. Budget constraints have an algebraic formulation which connects the variation of the public debt with
both the primary deficit (the difference between government spending and tax revenues), and the apparent
nominal interest rate of the public debt. For more details on this formulation, we direct the reader to Fève and
Hénin (2000), Berthomieu (2004), Leo (2005), Khoury, Colmant and Corhay (2008). Also there is a very
2. Public Debt In Lebanon: Cointegration Analysis And Forecasts1
www.theijes.com The IJES Page 84
extensive theoretical and empirical literature on the topic of sustainability of public deficit and public debt
(Mourad 2013). Two methods have widely been used to study the sustainability of the fiscal policy and public
debt: (a) the accounting method (Gabsi 2001) consists of a step by step evaluation, year by year, and allows
simulations for the future; this method is used by the IMF. (b) The "actuarial" method (Trehan and Walsh 1991,
Fève and Hénin 1998) uses econometric models such as the theory of cointegration and dynamic causality. The
accounting approach treats public debt as a percentage of GDP, using the current interest rate, the growth rate of
GDP, the budget deficit, the interest of the public debt, the expenses, and the revenues (Berthomieu 2004). The
actuarial approach is based on GDP, public debt, revenue and expenditure and the real rate of interest. This
paper will not use the above approaches, but envisions a cointegaration analysis of the Lebanese public debt
between, first the Treasury Bills at 12, 6 and 3 months (TB12, TB6 and TB3), second the Short Term and Long
Term Treasury Bills (TBST and TBLT) Bills, third the Global Local Currency Debt (GLCD) and the Foreign
Currency Debt (FCD), and then uses the estimated models VEC or VAR for forecasting. The available data
cover the period from January 1994 to May 2014 (245 months). The paper is organized as follows:
Section I as introduction. Section II presents an overview of the public debt in Lebanon. Section III reviews the
literature. Section IV uses Johansen’s procedure to study the cointegration between the components of the
public debt. Section V interprets the results and their political and economic impacts. While Section VI tries to
answer the following question: Where is public debt heading in Lebanon? Finally the conclusion is offered in
Section VII.
II. OVERVIEW OF THE EVOLUTION OF PUBLIC DEBT IN LEBANON
We will start by taking a look at the historical evolution of public debt in Lebanon.
Before 1975, the Lebanese economy experienced a period of prosperity and was one of the most dynamic
economies in the Mediterranean and Middle East: strong growth, low inflation, a surplus in the balance of
payments, fiscal equilibrium. At that time, the Lebanese state intervened relatively little in the economy and lead
conservative fiscal policies. In 1989, after the civil war, it was the signing of the Taif Agreement, which opened
a new era that laid the foundations for peace. Lebanon was faced with a double challenge: it was, on the one
hand, to rebuild the country with limited sources of funding, and on the other hand, to stabilize the
macroeconomic situation; it was a turning point in the contemporary history of the Lebanese economy after the
war. The Lebanese government opted for peace and tried rebuilding a completely crushed country after fifteen
years of domestic conflict and wars with Israel. This choice needed diplomatic efforts and economic policies to
address the financial needs that go far beyond the country's resources. At the end of 1992, with the first
parliamentary elections in twenty years and the appointment of a new government, the conditions of political
and economic stabilization were met. The growth rate reached 8% in 1994 (Femise 2005), and during this year,
the Lebanese government launched the reconstruction of downtown Beirut, which was destroyed during the war.
During that same period, the geopolitical situation, was being affected by the Iraq-Iran war, and by the invasion
of Kuwait by the Iraqi army; a war largely funded by the Arab Gulf. The Lebanese government was hampered
to seek financial loans from Arab Gulf countries. Hence, it was necessary for the government to resort to
domestic and foreign debt in order to support the reconstruction effort.
The consequence of such a choice was the gradual increase of the public debt in Lebanon. We recall that in the
past three decades, Lebanon experienced a relatively moderate level of foreign debt. Before 1978, there was no
such debt, while in 1989 the foreign debt was 41% of GDP (International Financial Statistics, Year Book 2000).
Indeed, the foreign debt was around USD 404 million in 1990 and USD 448 million in 1991; 14% and 10% of
gross domestic product (GDP) respectively. However, since 1993, the use of foreign funding by the Hariri
government lead to an increase in the foreign public debt of the country (figure 1). Thus, the amount of foreign
public debt gradually increased from 7.82% of GDP in 1992 to a peak of 90.62% in 2006, and then declined to
55.2% in 2011. The main reason for this increase in foreign debt was the conversion, since 1999, of a large part
of the domestic debt into foreign debt. This conversion took place for two reasons: (1) the foreign debt had
lower costs and (2) the financial account surplus was needed to offset the growing trade deficits. The foreign
debt ceiling until 1995 was at a level of USD 1.34 billion, while since 1996 it began to grow and reached in May
2014 a total of USD 26.228 billion. So the foreign debt became a serious preoccupation for Lebanon. The
question of repayment appeared to be very tormenting knowing that the investment capacity of the Lebanese
government became quite weak and increasingly got absorbed by the desire to service the debt. We must seek
funding sources based on steady growth and effective management of expenses.
It is well known on the international credit market that countries borrowing money have a grand interest to
repay their foreign debt because that affects the subsequent use of new loans; this gives countries greater
confidence on the part of international credit institutions (Oosterlinck and Szafarz 2005).

www.theijes.com The IJES Page 85
It is difficult to talk about public debt in Lebanon without mentioning the financial efforts at conferences Paris I,
II and III. The first conference was in 2001, the second in 2002, and the third in 2007. In the Paris I conference,
the World Bank and the European Investment Bank agreed to grant Lebanon a credit of EURO 500 million to
finance development projects. The second conference of Paris II allowed Lebanon to benefit from USD 4.4
billion of international credits at preferential rates (only USD 2.4 billion were actually paid). This amount was
meant to help advance a long term financing at noticeably lower interest rates than those previously granted to
the government on the domestic and international markets. These funds enabled a partial restructuring of the
public debt in Lebanon: they substituted the expensive debts and facilitated an agreement between the Lebanese
authorities and banks (main holders of the public debt) which agreed to exchange part of their portfolio against
cheaper debt. As a result, the domestic and foreign debts were established at short term with high interest rates,
and at long term with low interest rates. Though the allocation of long term credit came after Lebanon's
commitment to pursue a reform policy, including the privatization program, the reduction of the general
expenditures, and the rise of revenues. The international conference to support Lebanon (Paris III) came after
the terrible aggression waged by Israel in July 2006. That year, the GPD, which was USD 40.4 billion, made
Lebanon one of the most indebted countries in the world relative to its population estimated at 3.5 million. This
conference pledged an amount of USD 7.613 billion, yet the agreements were signed for USD 4.348 billion. In
return for these pledges, the Lebanese government was called to perform neoliberal economic reforms and had
to lower the GPD to GDP ratio from 180% (ratio observed at the end 2006) to 144%, possibly by the end of
2011. In fact the ratio exceeded expectations as it reached 134% in 2011. The GLCD rose during the period
1994-2013, from USD 4 billion to USD 37.354 billion; an annual increase of 11.8186%. Over the same period,
the GDP had a fluctuation between USD 9.6 billion and USD 43.49 billion; an annual increase of 7.8465%. We
note that the GPD rose from USD 4.35 billion in 1993 to USD 66.576 billion at the end 2014; from 57.7% to
148.62% to GDP ratio respectively. It is of great interest to study the structure of GLCD and see the evolution of
each of its components, especially treasury bills. Indeed, the GLCD is based on two main components: long
term bills and short term bills; both bills covered a total of 99.97% in May 2014. In fact, the loansare negligible
compared to these two main components (figures (2) and (3)). The Short term bills (TBST) are divided into
three components: TB12, TB6 and TB3 (figure 4). If we take into account the sources of debt, they can divide
the GLCD into four components which are the Central bank (CB), Commercial banks (COB), Loans to public
entities (Loans) and Non-Banking System Treasury Bills (NBS) (figure (5)).
4. Public Debt In Lebanon: Cointegration Analysis And Forecasts1
www.theijes.com The IJES Page 86
The Inspection of figure (2) provides important information about TBST and TBLT. In fact TBLT occupied the
majority of the GLCD since November 1996. Before that date the two components evolved close to one another
and recorded two crossings in September-October 1995 and October-November 1996. Inspecting the weight of
each type of bills in the structure of GLCD, we find that TBST recorded a small value in two different dates: 3%
at the end of October 2003 and 2% at the end of August 2008. While at those two dates, TBLT represented 96 %
and 97 % of GLCD respectively. Indeed, since 1995, the Lebanese government adopted a strategy of converting
short term debt into long term debt. Since November 1996, the percentage of TBLT varies between a minimum
of 51% in 1996 and a maximum of 96% in August 2008. In May 2014, the percentages of long and short term
bills are about 96.21% and 3.79 % respectively. However, the increase of TBLT’s weight in the GLCD raised
the dependence of the Lebanese economy on the international financial market. This dependence probably
reflects the vulnerability of the Lebanese economy.
The structure of foreign debt is composed of three components from which Euro bills occupy more than 80% of
its nominal value. The first government of the former Prime Minister Hariri in November 1992 faced a disaster
in the Lebanese economy after a devastating civil war which lasted from 1975 until 1989. In a country without
infrastructure, with a ripped public administration, and where militias replaced the state, everything had to be
rebuilt; the biggest problem was to find funding sources. The persona of Hariri, one of the first business men in
the Middle East, was a source of confidence for domestic and foreign creditors. Hariri was carrying an
5. Public Debt In Lebanon: Cointegration Analysis And Forecasts1
www.theijes.com The IJES Page 87
ambitious reconstruction project designed to put Lebanon back in its place in the regional economy. Yet the
public expenditure greatly exceeded collected taxes and customs revenues which were almost absent because
they were under the militias’ control. The force of the Lebanese pound did not quite withstand the civil war; the
Palestinian conflict, the Israeli invasion of Lebanon in 1982, the anarchy of public finances, the war
expenditures and the various speculations profoundly affected it. The exchange rate of one USD passed from
LBP 3.81 in 1982 to LBP 2800 in the summer of 1992. However, during this period, the Lebanese banking
system did not experience a collapse and Lebanon had no serious foreign debt; a stabilization policy based on
the exchange rate was decided in late 1992. In fact, since November 1998, the Lebanese authority fixed the
exchange rate within a very narrow range (less than ± 0.5%; 1 USD for LBP 1507.5). With the start of the first
government of Mr. Hariri, the public debt was almost centered on domestic debt (figure 6). Indeed, interest rates
fluctuated between 18% and 42% during the period 1992-1998. This policy increased the GLCD from USD
6.21 billion in 1994 to USD 14.41 billion in 1998 (an increase of 232%).
We conclude this section by noting that in 2010 the majority of the FCD was in USD (87.3%), in EURO (7.8%),
in Kuwaiti Dinars (2.55%), and the remaining 2.39% cover other currencies like Saudi Arabian Riyals, Japanese
Yen, etc (Lebanese Ministry of Finance). The structure of the FCD by the end of September 2012 was 88.4%
ofEurobonds, 11.3% of loans and 0.3% of other debt.
III. LITERATURE AND EMPIRICAL REVIEW
It is necessary to mention the main research which lead the cointegration analysis in the economic and financial
time series, we mean the Engle & Granger method (1987) and the procedure proposed by Johansen (1988) and
Johansen &Juselius (1990).We mention a recent paper for Mourad (2014) which treated the cointegration
between unemployment, GDP and public debt in Jordan and another paper (Mourad 2013) that did structural
analysis and forecasts of the public debt in Lebanon with its various components. Three main results have
emerged out of this paper. First, the FCD and GPD to GDP ratios have a similar trend. The two ratios turned
out to be cointegrated according to Engle and Granger’s two-step procedure. Second, the debt ratios take a
downward trend in the ex-ante forecasts for the period 2013-2015, revealing a dynamic sustainable debt in
Lebanon. In parallel, the debt ratios turned out to be non-stationary indicating an ineffective sustainability. At
the level of the use of the cointegration analysis according to Johansen’s procedure, we mention Salame and
Chikhi (2013) for causality testing and cointegration between savings and investment in the Algerian economy,
Al-Tayeb et al (2011) for the impact of interest rate on private consumption in Jordan, Cholifihani (2008)
analyzed the long term and short term relationships between public debt service and GDP in Indonesia and it
adopted a function model that measured GDP as a function of debt service, capital stock, labor and human
capital in which all data are represented by constant local currency unit. The result shows that increasing the
public external debt service slows economic growth and the elasticity of GDP will decrease if debt service
increases and if the elasticity of GDP to human capital is relatively small. Mourad and Farhat (2007) elaborated
a cointegration study of the foreign direct investment between five global regions: Western Europe, North
America, other Developed Countries, Developing Countries and Central-Eastern Europe. We also note an
important paper, Bou-Hamad et al (2013), which treated the annual foreign trade between the GCC and the
United States, and concluded that no cointegration exists between the export and import ratios for each GCC
country and the United States. A paper published by Mourad and Harb (2013), dealt with the cointegration
regression analysis, according to the Engle & Granger procedure, for the exchange rate of EUR/USD in daily
data considering the opening, the highest and the smallest prices. Finally, we refer to the newly issued book for
Mourad (2015) entitled “Population Growth and Development Prerequisites in the GCC States”, as it deals with
the cointegration method proposed by Engle-Granger.

IV. COINTEGRATION ANALYSIS
This section focuses on the implementation of the cointegration analysis on the public debt in Lebanon using
Johansen’s procedure on three groups of variables: (TB12, TB6, TB3), (TBST, TBLT) and (GLCD, FCD).
To decide about the second-order stationarity, we will use the Augmented Dickey-Fuller (ADF), proposed by
Dickey & Fuller (1981).
In table (2), we present the results of the ADF statistics:
We conclude that all level variables are non-stationary and can be made stationary by taking their first
difference; they are said to be integrated of order 1 (at 5 % level of significance) and denoted as I(1).
The Johansen Procedure requires identifying the order of cointegration using either the trace test 𝜆𝑡𝑟𝑎𝑐𝑒 or
𝜆 𝑚𝑎𝑥 test. Though it will be limited to the first test, as generally both tests lead to the same decision.
According to Hendry &Juselius (2000), three cases will be considered:
Case I: No deterministic trend for the variable in level, cointegrating equation without constant; there is no drift
in the ECM model.
Δ𝑋𝑡 = Г𝑖
𝑝−1
𝑖=1 Δ𝑋𝑡−𝑖 + 𝛼𝛽′𝑋𝑡−1 + ɛ𝑡
Case II: Deterministic trend for the variable in level, cointegrating equation without constant.
Δ𝑋𝑡 = Г𝑖
𝑝−1
𝑖=1 Δ𝑋𝑡−𝑖 + 𝛼𝛽′𝑋𝑡−1 + 𝜇+ɛ𝑡
There is a separate drift in the ECM model. This implies that the first-differenced variables in the ECM do not
have the same mean. And thus the level variables may have different growth patterns though they have common
stochastic growth patterns. A Monte Carlo study, realized by Crowder (2001), revealed that a VEC model with
linear trends in the data has better power properties than the other Johansen Likelihood Ratio (JLR) tests.
Case III: it specifies a model with a constant restricted to the cointegrating space: no deterministic trend for the
level variables, cointegrating equation with constant.
Δ𝑿𝒕 = Г𝒊
𝒑−𝟏
𝒊=𝟏 𝚫𝑿𝒕−𝒊 + 𝜶(𝜷′, 𝜷 𝟎)(𝑿′
𝒕−𝟏
, 𝟏)′ + ɛ𝒕
This model implies that the first-differenced variables in the ECM have a common mean.
In all cases, the vector ɛ 𝒕 = ɛ 𝟏𝒕, … , ɛ 𝒅𝒕 ′denotes the vector of error terms that are assumed to be white noise. To
test the null hypothesis that ɛ𝒕 is independent of ɛ𝒕−𝟏, … , ɛ𝒕−𝒔, the Ljung-Box portmanteau test for autocorrelation
can be applied. This test statistic in its multivariate form is defined according to Hosking (1980) (see also
Hatemi(2002)).
To identify the optimal order of the VAR model, we will use the automatic selection criteria AIC and SBC, then
the Ljung-Box statistic can be used to control the validation of the residuals like a white noise. The results are
given in table (4).

Inspecting this table, we find that both AIC and SBC criteria under-estimate the autoregressive order of the
VAR model in levels. For this, we have overcome the proposed order to ensure errors like a white noise. In table
(5), we have grouped all the test results according to Johansen’s cointegration considering the three cases cited
above. We selected for each system and for each case, the eigenvalues and the trace-statistics according to 95%
quantile values. In cases where the cointegration is accepted, the cointegration relationship was written. In all
three cases, each of the two systems (TB12, TB3 and TB6) and (STB and LTB) is cointegrated at rank 1. While
the system (GLCD and FCD) is cointegrated at rank 1 in cases 2 and 3.

For the systems (TB12, TB6,TB3) and (TBST,TBLT), the cointegration was accepted for the three cases (I, II

VEC model appears to be white noise. The Ljung-Box Q-Statistics at 48 degrees of freedom and at 5 %
significance level are respectively 48.7, 66.6 and 58.3 for the first, second and third equations.
B- Estimation of the VEC model of the system (TBST,TBLT) = (X ,Y):The estimate near-VECM model is:
𝜟𝑿𝒕 = 𝟎. 𝟑𝟑𝟑𝜟𝑿𝒕−𝟏 + 𝟎. 𝟏𝟏𝟒𝜟𝑿𝒕−𝟕 + 𝟎. 𝟎𝟖𝟏𝜟𝒀𝒕−𝟑 − 𝟎. 𝟎𝟑𝑪𝑶𝑰𝑵𝑬𝑸𝒕−𝟏

coefficients, the error correction term 𝑪𝑶𝑰𝑵𝑬𝑸𝒕−𝟏 has the correct sign (-0.03) for the equation associated to the
variable 𝜟𝑿𝒕 and it is negative enough (-2.96). Moreover the estimate coefficient on the 𝑪𝑶𝑰𝑵𝑬𝑸 𝒕−𝟏 associated
to the second equation (variable𝜟𝒀𝒕) is positive enough (t ratio = 4.17) and by consequence the stability
conditions for the VEC model are ensured.
C- Estimation of the VEC model of the system (GLCD,FCD) = (X ,Y):
In fact, we estimated a VEC model for this system. But it is not validated because the estimate coefficient on the
error correction term for the first equation (variable 𝜟𝑿𝒕) is not negative enough (t ratio= -1.31) and hence the
relationship between GLCD and FCD is spurious. For this reason, we re-estimated the near-VAR (39) model,
and obtained the following:
𝜟𝑿𝒕 = 𝟎. 𝟏𝟖𝟒 + 𝟎. 𝟏𝟐𝟐𝜟𝑿𝒕−𝟐𝟑 + 𝟎. 𝟏𝟗𝟐𝜟𝑿𝒕−𝟑𝟕 − 𝟎. 𝟐𝟗𝟔𝜟𝑿𝒕−𝟑𝟖

The forecasts for the period May 2015 are given in figure (7).
V. RESULTS AND THEIR POLITICAL AND ECONOMIC IMPACTS:
As it was shown in the paper, three random vectors are present: the first vector contains the treasury’s short term
bills (3, 6 and 12 months) which were represented by TB3, TB6 and TB12 respectively. The second vector
contains two variables, as from the gross local currency debt (GLCD): short term treasury bills (TBST) and long
term treasury bills (TBLT). The third vector contains the gross local currency debt (GLCD) and the foreign
currency debt (FCD). The analysis will focus on both the short term and long term impacts of the results.
Cointegration between short term bills TB3, TB6 and TB12:
Cointegration was accepted for the three cases (I, II and III), this is why the focus will be on the third case (no
deterministic trend for the level variables, cointegrating equation with constant) due to the significance of the
constant parameter at 10% level.
According to figure (4), TB12 has the bigger amount in TBST followed by TB6 and TB3 respectively. Based on
a period of 245 months, we found that the means for short term bills have the following percentages: 58.75% for
TB12, 32.14% for TB6 and 9.11% for TB3.
The long term relationship (target) between TB3, TB6 and TB12 is as follows:
𝐓𝐁𝟏𝟐 = 𝟏. 𝟐𝟗𝟖𝐓𝐁𝟔 + 𝟓. 𝟏𝟎𝟐𝐓𝐁𝟑 − 𝟎. 𝟕𝟕𝟕
(2.9) (6.65) (-1.84)
The above relationship shows that any short term deviation of the variable TB12 will be corrected during the
consequent month by 3.07%. Let us assume a 1% increase in the variable TB6, while keeping constant TB3,
then TB12 will increase by 1.298%. While an increase of 1% in the variable TB3, with a constant value of TB6,
will increase TB12 by 5.102%. Financially speaking this implies the following: if the Lebanese government had
10. Public Debt In Lebanon: Cointegration Analysis And Forecasts1
www.theijes.com The IJES Page 92
to issue three months treasury bills, then this means that it is doing so to pay for accrued bills, or to pay for
sudden changes in local affairs, and this is an important indicator for the necessity to issue twelve months
treasury bills that are 5 times higher than those in the three months category.
Short term treasury bills (TBST) had great importance at the start of January 1994, since they formed 52% of
the gross local currency debt and even peaked at 66% in May 1996, and due to the Israeli aggression on
Lebanon in April 1996 (Operation Grapes of Wrath) which resulted in the destruction of homes, schools, power
plants, wells, local businesses and factories, the Lebanese state had to borrow from the short term bills in order
to quickly rebuild some of the destroyed infrastructure. These bills had high interest rate, 15.75% for TB3,
17.07% for TB6 and 18.04% for TB12, and this is clearly shown in figure (4). The importance of short term
bills started to slowly fade only to rise up again at the time of the assassination of Prime Minister Rafic Hariri in
February 2005, as it reached 25.35% of the gross local currency debt in March 2005. After this period, short
term bills decreased and reached 3.78% of the gross local currency debt in 2014. And to give a more realistic
image of the cost of this type of gross local currency debt, we can see that the interest rates (yields) are currently
at of 4.44% of TB3, 4.99% of TB6 and 5.35% of TB12, and these are very low values compared to previous
years. This reflects the capability of the Lebanese state in using long term treasury bills, which have reached
96% of the gross local currency debt in May 2014, while its lowest was in May 1996 with 32.77%.
Cointegration between short term bills (TBST) and long term bills (TBLT):
These two variables are at the basis of the gross local currency debt (99.77% in May 2014). The long term
relationship between TBST and TBLT is as follows:
𝐓𝐁𝐒𝐓 = −𝟎. 𝟏𝟎𝟖𝐓𝐁𝐋𝐓 + 𝟑. 𝟒𝟕𝟗
(-4.51) (7.49)
This linear relationship reflects the very important long term equilibrium between the two variables. If the
amount of TBLT increased by 1 billion USD within the GLCD, then the TBST will decrease by 108 million
USD. To expand on this subject let us inspect the yield on long term bills. Four types of long term bills are
available: TB24, TB36, TB48 and TB60 with the following respective interest rates: 5.93% 6.61%, 10.3%
(coupon rate) and 6.74% (coupon rate). It is worth noting that TB48 was last used in April 2005. Thus, it is clear
that the Lebanese state will benefit from long term bills because their cost will be lower than short term ones.
And if we examine the VEC model for TBST and TBLT in the first difference, we will clearly see how TBST
returns to its target of 3% in just one month.
Near-VAR (39) model for GLCD and FCD:
The vectors composed of the gross local currency debt (GLCD) and the foreign currency debt (FCD) are not
cointegrated, this is why the near-VAR (39) model was used to explain the dynamic relationship between the
two in the short run and also to make forecasts. It is worthy to note that at the end of the year 2014, the local
debt and foreign debt had reached 40.963 billion USD and 25.613 billion USD respectively, which in their turn
represent 61.528% and 38.472% from the total public debt.
VI. WHERE IS PUBLIC DEBT HEADING IN LEBANON?
At the end of the year 2013, the GDP in Lebanon was USD 44.352 billion while public debt was USD 63.473
billion which gives a ratio of 143.124%. The World Bank predicted that by the end of the year 2014, the GDP in
Lebanon would be around USD 44.796 billion while public debt would be USD 66.576 billion (ratio of
148.62%). At the same time, the Lebanese economy is going through a clear slow down due to various reasons,
especially the Syrian crisis which has split the Lebanese political scene. Also, it was estimated that around 1.5
million Syrian refugees have sought Lebanon at the end of the year 2014, according to the United Nations. For
the same time period, the Lebanese population was at around 4.5 million people, and the number of Palestinian
refugees has reached half a million according to the UNRWA,
and let’s not forget the huge numbers of foreign
workers, especially the highly demanded house maids which according to the Human Rights Watch are around
200 thousand worker (a ratio of 1 worker for each 16 families). As a total, about 7 million people are living over
an area of 10,452 km2
which gives a density of 670 person/km2
.
However, and with regards to all of this and amidst turbulent regional conflicts, the Lebanese population still
lives relatively well, especially those families which depend on working abroad. It is well known that Lebanon
highly depends on money transfers from its expatriates; according to the World Bank, the year 2014 had about
USD 8 billion. Lebanon ranks 18th
among largest recipient of remittances worldwide and 2nd
among Arab
countries. In fact, important factors in that growth are the money transfers sent by Syrian expatriates abroad to
their refuged relatives in Lebanon, as well as the improvement of the economic situation in some of the key
countries hosting Lebanese expatriates like the United States. We also note that the accumulated deposits in
Lebanese commercial banks are not being beneficially invested. When Lebanon resorts to short term bills, then
11. Public Debt In Lebanon: Cointegration Analysis And Forecasts1
www.theijes.com The IJES Page 93
naturally long term bills decrease, in other words, resort to the financial market decreases. It is known that
investors usually aim for a quick and big profit, this is why they will refrain from long term investments. Here
comes the role of the Central Bank to be an effective link transferring the monetary market to the long term
financial market. In the latest statistic by the Central Bank, at the end of April 2015, the deposits of non-
residents in Lebanese Pounds (equivalent in USD) and in foreign currencies have reached USD 27.144 billion
and USD 4.106 billion respectively (exchange rate: 1 USD = 1,507.5 LBP). While at the same time the total
deposits in foreign currencies reached USD 96.310 billion and deposits in Lebanese pounds reached an
equivalent of USD 51.186 billion. This brings the total deposits in commercial banks to USD 147.496 billion.
What do these numbers represent? And how do they affect the public debt?
Based on the latest statistic from the Lebanese Central Bank (April 2015) on the gross public debt, which
reached USD 69.456 billion, in comparison to the total deposits in commercial banks, around USD 147.496
billion (a ratio about 47%) we clearly see the capability of the Lebanese people in strengthening the global trust
in Lebanese banks. This helps Lebanon in gaining the confidence of global financial institutions by obtaining
more long term bills; this is evident now as according to the Lebanese Ministry of Finance, the largest foreign
currency bills (Eurobond) in the history of Lebanon were issued (an additional 2.2 billion)to cover financial
needs in the year 2015. Also, and according to the current Minister of Finance, this was a very successful
issuance due to its low cost compared to previous issuances. This issuance was divided into two parts, the first
having a value of USD 800 million due in 2025 with a rate of return of 6.2%, while the second part had a value
of USD 1.4 billion due in 2030 with a rate of return of 6.65%. On the international level, Lebanon has been
known to carefully and fully abide by international banking standards. This of course benefitted its banking
sector as western countries, especially the United States, regard it with great trust.
On both international and regional levels, Lebanon has been able to successfully remain economically stable,
especially regarding exchange rates. Even though Lebanon has been living in turmoil since 2005, after the
assassination of Ex-Prime Minister Rafiq Hariri, followed by the devastating Israeli aggression in 2006, which
only aggravated the tension in the political scene; which the negative consequences still echo to this day. In
addition to all of that, we should not forget, the damaging impact of the Syrian war, as well as the unrest in
many Arabic countries and the consequences of the global financial crisis in 2008. One of the main factors in
the stability of exchange rates is the policy adopted by the Lebanese Central Bank. This policy was able to
hinder unemployment as it kept it at around 8.9% (2009-2012). It also kept a steady control over inflation
(average inflation rate for 2009-2013 was 4.25% according to the World Bank); this retained the capability to
have low interest rates which guaranteed stable return for both creditors and debtors. The Lebanese Central
Bank was among the first to apply Basel III , this obliges the Lebanese banks to a minimum capital assets ratio
of 12% in 2015; instead of 2019 (date of fully applying the agreement). This affirms global trust in Lebanon
regardless of the heavy load that is public debt.
Before finishing this section, the consumption expenditure in Lebanon must be mentioned; this represents the
general governmental plus the household final consumption expenditures. This expenditure generally surpassed
the GDP: in 1990 and 2011, it represented 164.14% and 101.21% of the GDP respectively. This means that the
gross domestic saving, the difference between the GDP and consumption expenditure, was negative in the
period between 1990 and 2011.
According to the World Bank, this saving noticeably improved in 2012 and 2013 because of the clear decrease
in the consumption expenditure especially the household final consumption expenditure, as the savings for both
years were 8.83% and 14.275% respectively. This kind of improvement in local savings can be attributed to the
Lebanese families and their fear of a sudden deterioration in security due to the war in Syria, and to the absence
of an elected president for more than a year. We should also point out that during the global financial crisis,
from 2007 till 2013, the gross capital formation (% of GDP) was around 26.71%.
VII. CONCLUSION
At the end of this research, we are pleased to mention some of the results derived from our near-VAR and near-
VEC models proposed for the different systems of the Lebanese public debt. The first is of informational nature
concerning the different components of this debt. We note that domestic debt comes from the commercial banks
and the central bank, and it represents a ratio ranging from a minimum of 67.49% (June 1997) and a maximum
of 86.91% (January 2006). The ratio of the gross local currency debt (GLCD with respect to GPD) ranges from
47.47% in February 2005 and 94.41% in July 1994. The short term treasury bills (TBST) and long term
treasury bills (TBLT)hold a ratio of GLCD ranging a minimum of 98% and a maximum of 99.8% between
January 1995 and May 2014. TBLT represents a ratio of GLCD between 90.78% and 96.51% for the last five
years (May 2009-May 2014). The second point of our conclusion is drawn from the cointegration analysis
according to the JLR statistic (Johansen Likelihood Ratio). The components of the vector (GLCD, FCD) are not
cointegrated and they are modelled by near-VAR (39). The forecasts for May 2015 are respectively USD 40.158
billion and USD 27.375 billion. Since the estimated near-VAR model reveals bidirectional causality between
12. Public Debt In Lebanon: Cointegration Analysis And Forecasts1
www.theijes.com The IJES Page 94
GLCD and FCD, we will give more confidence to forecasts made by the VAR model. This allows us to estimate
respectively monthly growth rates of 0.2788% and 0.3588% from May 2014 until May 2015. With the most
confident result, the domestic debt would grow more slowly than the external debt. For the components of the
vector (TBST TBLT), they are cointegratedin case III (a constant in the cointegrating relationship). One percent
increases in TBLT, the elasticity of TBST decreases by 0.108 percent. The components of the vector (TB12,
TB6, TB3) are cointegrated in the three cases (I, II and III). Inspecting the equilibrium relationships in case III,
we note that if one percent increases in TB6 (TB3 remaining constant), the elasticity of TB12 increases by
1.298%. While if one percent increases in TB3 (TB6 remaining constant), the elasticity of TB12 increases by
5.102%. This means that TB3 is the main variable to support TB12 in the long run. For the systems (TBST
TBLT) and (TB12, TB6, TB3), the available forecasts for May 2015 are respectively (0.766,39.568) and (0.734,
0.544,0.153).
Before ending this conclusion, and based on our paper entitled "Public Debt in Lebanon: Structural Analysis and
Prediction" published in IRJFE (November 2013), the forecast of GDP for 2013 was around USD 46 billion but
unfortunately the political conflicts in the regions of the Middle East deprived Lebanon of its economic growth
especially in the tourism sector which is the main economic resource of the country; this had a negative effect
on GDP estimated at 43.49 billion in 2013 (a huge loss of about USD 3 billion). This new situation has dramatic
consequences for the solvency of the Lebanese state. Indeed, if the internal political conflict in Lebanon
continues then the Lebanese state will not keep public debt under control, and the sustainability of public
finances will not be stable.
Finally, we focus on the following points:
First, despite the divergence of the Lebanese political scene vis-à-vis the dramatic crisis in Syria and in other
Middle Eastern countries, and despite the slowdown in economic growth in the country followed by a reduction
in the household consumption, the commercial banks testify prosperity in deposits of residents and non-
residents. These banks recorded in April 2015, a total of USD147.496 billion, that is to say 212.359% of the
gross public debt. This reassures the global financial companies that will be willing to offer Lebanon long term
bills with relatively low interest rates. In return, this will slowly but surely lower the ratio of internal debt to
public debt.
Second, the Lebanese Central Bank was able to retain the stability of the financial markets especially regarding
exchange rates.
Third, for the period 2010-2014, Lebanon has been subject to slow economic growth; the average GDP yearly
growth was around 4.2% while public debt grew by a yearly average of 6.11%. This means that Lebanon cannot
start a plan to lower public debt while its progression is still higher than the economic growth. In order to
achieve true improvement and economic growth in Lebanon, the ruling politicians must agree on a national plan
that will protect Lebanon from falling into turmoil like neighbouring Arabic countries.
Fourth, political stability and focus on tourism must be priorities as Lebanon has great touristic potential due to
its Mediterranean weather, the wealth of historical monuments and sites, and many cultural festivals.
Fifth, and this may be the most important point, the Lebanese state must form a “Petroleum Sector Management
Authority”, and to immediately start drilling for oil in Lebanese territorial waters in the Mediterranean
especially that surveys conducted by the Lebanese Ministry of Energy and Water in 2002 yielded positive
results as there might be oil at around 60km of the Lebanese coast. And of course this will need high long term
financial investments that could be gathered from the global financial market.
