Porter's influential study on the competitive advantage of nations inspired a methodologically

endogenously by means of statistical cluster techniques. Avoiding his "cut-off" approach, "well-"
and "badly" performing industries are the objects of analysis. The resulting cluster centers
constitute the typical pattern of competitiveness for the chosen trade indicators, while the
classifications produce a "map" of Austrian industrial export performance. The results further show
that: 1) clustered industries generally are rare in the case of Austria; 2) some of them are located
in declining, crisis-shaken sectors; and 3) competitiveness underlines the importance of
transnational links (as opposed to narrow national boundaries) for the formation of successful
industries. (JEL L10)
To analyze the factors affecting the price volatility of stocks, microeconomic and macroeco-nomic elements must be considered. This paper selects elements that are appropriate with the daily data of stock prices to build the GARCH family models. External variables such as global oil prices, consumer price index, short interest rates and the exchange rate between the United States Dollar and the Euro are examined. The GARCH models are developed in order to analyze and forecast the stock price of the companies in the DAX 30, which is Germany’s most important stock exchange barometer. The volatility of the residual of the mean function is the important key point in the GARCH approach. This financial application can be extend-ed to analyze other specific shares or stock indexes in any stock market in the world. There-fore, it is necessary to understand the operating procedures of their pricing for risk manage-ment, profitability strategies, cost minimization and, in addition, to construct the optimal port-folio depending on investor’s preferences.
Novel price models in the capital marketAsoka Korale
In one contribution we estimate the random process governing the movement in the price and simulate a series of realizations drawn from the same underlying process to gain insights in to unusual behavior that could manifest. In this modeling we estimate the distribution of the sequence of random variables governing the prices and generate a series of realizations or paths with the same underlying distribution. We also develop an equation to predict the expected deviation in price between two points in a sequence of prices and a measure of the uncertainty in this deviation.
In another contribution we model prices as a linear regression on consecutive prices to estimate its movement and arrive at an estimate for the distribution in the error of such a prediction. By these techniques we estimate the trend and maximum deviation in price that could be expected over a sequence of prices in order to optimize the alert thresholds.
Through these analyses we also observe that the variance in the price is dependent on the number of samples in a sequence of prices over which the measurement is made due to the behavior of the random process governing its movement and propose that the variance be estimated over a fixed number of consecutive prices ensuring a more stable and consistent estimate.

The gravitation process of market prices towards production prices is here presented by means
of an analytical framework where the classical capital mobility principle is coupled with a determination
of the deviation of market from normal (natural) prices which closely follows the description provided by
Adam Smith: each period the level of the market price of a commodity will be higher (lower) than its
production price if the quantity brought to the market falls short (exceeds) the level of effectual demand.
This approach also simplifies the results with respect to those obtained in cross-dual literature. At the
same time, anchoring market prices to effectual demands and quantities brought to the markets requires a
careful study of the dynamics of the ‘dimensions’ along with that of the ‘proportions’ of the system.
Three different versions of the model are thus proposed, to study the gravitation process: i) assuming a
given level of aggregate employment; ii) assuming a sort of Say’s law; iii) and on the basis of an explicit
adjustment of actual outputs to effectual demands. All these cases describe dynamics in which market
prices can converge asymptotically towards production prices.

Garch Models in Value-At-Risk Estimation for REITIJERDJOURNAL
Abstract:- In this study we investigate volatility forecasting of REIT, from January 03, 2007 to November 18, 2016, using four GARCH models (GARCH, EGARCH, GARCH-GJR and APARCH). We examine the performance of these GARCH-type models respectively and backtesting procedures are also conducted to analyze the model adequacy. The empirical results display that when we take estimation of volatility in REIT into account, the EGARCH model, the GARCH-GJR model, and the APARCH model are adequate. Among all these models, GARCH-GJR model especially outperforms others.

The case study discusses the potential of drone delivery and the challenges that need to be addressed before it becomes widespread.
Key takeaways:
Drone delivery is in its early stages: Amazon's trial in the UK demonstrates the potential for faster deliveries, but it's still limited by regulations and technology.
Regulations are a major hurdle: Safety concerns around drone collisions with airplanes and people have led to restrictions on flight height and location.
Other challenges exist: Who will use drone delivery the most? Is it cost-effective compared to traditional delivery trucks?
Discussion questions:
Managerial challenges: Integrating drones requires planning for new infrastructure, training staff, and navigating regulations. There are also marketing and recruitment considerations specific to this technology.
External forces vary by country: Regulations, consumer acceptance, and infrastructure all differ between countries.
Demographics matter: Younger generations might be more receptive to drone delivery, while older populations might have concerns.
Stakeholders for Amazon: Customers, regulators, aviation authorities, and competitors are all stakeholders. Regulators likely hold the greatest influence as they determine the feasibility of drone delivery.

INTRODUCTION
Porter's [1990] influential study on the competitive advantage of nations inspired this
methodologically extended work on Austrian data. Basically building upon Marshall's [1920]
insights into the regional concentration of economic activities, Porter strongly emphasizes the
importance of industrial clusters, characterized by the presence of successful horizontally related
firms, as well as vertically supporting industries. Dense informational structures with significant
externalities, intense competition, lower transaction costs, and cooperation and greater weight in
political lobbying feed a self-reinforcing process of dynamic competitive advantages and growth
(for more details, see Hutschenreiter and Peneder [1994]).
However, a major methodological problem in Porter's analysis--where no cluster techniques in
their literal (i.e., statistical) meaning are applied--is its determination of competitiveness of
different industries by exogenously given boundaries on performance indicators (e.g., market share
x% above a country's average). In addition, all industries performing below this level are
eliminated for the rest of the analysis, with the implicationthat no informationon badly performing
industries is retained.
Taking Porter's cluster analysis literally, competitiveness is determined endogenously by means
of statisticalcluster techniques in this paper. Furthermore, avoiding his cut-off approach, well- and
badly performing industries are the objects of analysis. As cluster techniques are descriptive by
nature, what will be gained are better insights into the composition of competitive and non-
competitive industries within a country, whereby the multidimensionalcharacter of the phenomenon
"competitiveness" is explicitly acknowledged. This paper demonstrates on behalf of Austrian data

how clustering techniques can be applied to create a profile of a country's industrial performance.
Finally, conclusions about the importance of clustered industries in Austria will be drawn.
ANALYZING PATTERNS OF INDUSTRIAL COMPETITIVENESS
Statistical clustering techniques provide a classification scheme of individual observations,
depending on their relative similarity or nearness to an array of different variables. These
classifications are determined endogenously by the individual data and the chosen cluster algorithm.
The basic idea is one of dividing a country's overall performance profile into segments by creating
maximum homogeneity within and maximum distance between groups of observations.
Although it is a frequent objective in applied economic research, competitiveness as a concept
has stayed rather vague and lacks a universally accepted definition, as well as a broad consensus
on the appropriate empirical measure [Bellak, 1992]. "The ability to earn sustainable and high
incomes while at the same time being able to maintain and improve on social and environmental
standards" [Aiginger, 1987] may be the best definition of industrial competitiveness on an abstract
level, because it demands measurement that goes beyond the more quantity-based indicators like
trade specialization or market shares alone. The "ability to earn sustainable and high incomes"
depends as well on quality indicators and, accordingly, on the level of prices that can be charged.
Reflecting both the quantitative as well as qualitative dimensions of competitiveness, four
variables have been chosen to enter the clustering algorithm in standardized form on the basis of
mean values for the years 1990-92. Their underlying symmetric structure guarantees their implicit
equal weighting in the clustering process, as is displayed in Table 1. Actually, there is a significant
correlation between two pairs of variables, namely between market shares and trade specialization,
as well as between comparative price advantage and relative export unit values. Both of them are
no big surprise, since each pair share one common factor, which are export values and export
prices, respectively. But none of them could be labelled redundant; MAS offers information about
the relative importance of an industry on an international level and TSP on the national level. CPA
gives analogous insights into the vertical composition of prices, while RUV does so horizontally.

After the set of variables has been chosen, an optimization cluster technique, based on the
minimization of within-group dispersion, is used to classify 208 product groups (SITC, three-digit)
into clusters of maximum homogeneity according to these indicators of trade performance. In this
first step of the analysis, the set of observations is divided by a pre-defined number of clusters g.
Then cluster-centers are estimated for each group, which are vectors with means of the
corresponding for each variable. The optimization criterion is given by the trace of the matrix of
within-group dispersion W (of dimensionp x p variables), which consists of vectors x~j for thejth
observation in the ith group and the according cluster-centers:
nl
IV- 1 ~ F_,(xij-xi) (xij-xi)' (1)
n-g i=1j=l
Minimization of trace (W) is done by iterative algorithms, where the position of the cluster-
centers are varied until the process converges. Convergence means that there is no additional
alteration that improves the clustering criterion above a prespecified value. However, the
exogeneity of the total number of clusters g that shall be obtained and has to be chosen in advance
by the researcher remains a serious problem with optimization techniques. In spite of the fact that
this choice of g can have a major impact on the final results, there exists no general rule for its
determination. To partly overcome this difficulty, the following self-binding rule of thumb was
applied in the current analysis: "Choose the lowest number g that maximizes the quantity of
individual clusters which include more than 5 percent of the observed cases." According to this
rule, the number g = 21 clusters, producing eight clusters comprising more than 5 percent of total
observations, was identified to be able to represent the underlying structure best. The resulting
outcome is an endogenous classification of all observations into the given numbers of clusters.
From the results of this first step in the clustering procedure alone, it is difficult to interpret the
underlying performance pattern. Therefore, a second step in the clustering process is executed, in
which the resulting 21 clusters of the first step enter a hierarchical clustering algorithm as
observations with their according cluster-centers as values. Hierarchical techniques are based on
a quadratic distance matrix D (of dimension n x n observations) that contains a chosen measure of
relative distance dij between any pair of n observations according to their attributes. Distances can
be calculated in a variety of ways [Romesburg, 1984; Everitt, 1993]. The measure most commonly
used and also applied in this analysis is squared Euclidean distances, which measures the
dissimilarity of two observations i and j with respect to the chosen set of p variables as follows:
dij =I P! k=l
~ (xik - Xjk )2 0 <£ aij <( oo (2)
In the following agglomerative algorithm of hierarchical cluster analysis, initiallyall observations
are treated as independent single clusters. So there are as many clusters as observations. In the
iterative process, distances of all pairs are compared and those with minimum distance are clumped
together to form a common cluster. Average linkage measures the distance of the newly formed
agglomeration by the average distance of all single pairs between an observation outside and each
observation inside the cluster. At any step of the iteration, the new distance matrix loses one row
and one column, so that its new dimension is n - 1. This process is continued until all observations
are part of one large, single agglomeration. This is when the algorithm finds its natural end. It is

important to note that, contrary to optimization methods, the process of hierarchical clustering is
irreversible. The outcome is a hierarchical structure, beginning with many single observations that
finally join each other at different levels until they are all united by one single trunk.
The graphical representation of the hierarchical clustering algorithm in Figure 1 shows the
hierarchical structure of relative closeness in the performance patterns. The sooner individual
clusters are clumped together by the vertical lines, the more similar is their performance pattern.
Unfortunately, seven of the eight clusters with more cases than 5 percent of the overall observations
are clumped together in one single agglomeration at the top of the figure. This second step in the
clustering process has merely structured the relative similarity of those small clusters that usually
include only one or few observations that constitute very special cases in terms of international
competitiveness.

PANORAMA OF AUSTRIAN TRADE PERFORMANCE
The overall profile of Austrian industrial performance for the years 1990-92 is shown in Figure
3 and Table 2. The panorama results from a regrouping of the 21 clusters defined in step one of
the clustering process according to the relative relatedness in performance levels discovered in steps
two and three. For all of the four performance indicators, the surface of this panorama exhibits the

mean values of the standardized data for each cluster. Since the four variables are based on the
distinction between export volumes and export prices, the resulting pattern of different levels of
competitiveness also exhibits the same dichotomy. The number of observations comprised in each
cluster is given in parantheses.

Analogous to population densities in "alpine" regions, to locate near the top is tough and only
a very small number of "peak" performers can afford to live there. The majority of product groups
belongs to the lower regions of industrial performance (Levels Ixv, N, 0, Ixp). Mountainous
"peaks' to the left refer to those clusters which show extraordinarily high values in terms of export
volumes (Levels Ilxv and III). Those to the right refer to high values in terms of export prices
(Level Ilxp). The different performance levels, which have resulted from the regrouping of the 21
clusters according to the information gained in steps two and three, are interpreted as follows:
Level N-- "Non-performer:"According to Figure 2, clusters 20 and 13 can be combined into
a common performance level. Together, they comprise 54 cases where Austrian
manufacturing can best be labelled as non-performing. Examples are some base metals like
lead or zinc, perfumery and cosmetics, computers, road motor vehicles, and aircraft.
7. AUGUST 1995, VOL. 1, NO. 3 301
Level Ixp-- "Badly" performing industries that hold at least an average position in terms of
export prices: Cluster 15 includes 32 cases which perform badly according to market shares
and trade specialization, but at least get average relative export unit values and values for
comparative price advantage. Examples are fertilizers, feeding stuff for animals, office
machinery, parts of motor vehicles, and instruments for medical, surgical, and dental
purposes.
Level Ilxp--Industries competing in small niches of the product spectrum, characterized by
highprice levels but low export volumes: Clusters 3 and 16 are characterized by high values
in terms of export prices and low valUes in terms of export volumes. These industries
generally cannot compete on an international level, but at least perform some high-priced
quality strategy in small niches of the product spectrum. However, interpretation must be
cautious, since data on unit values can be very erratic in cases of small trade volumes. The
same argument applies to a number of very heterogeneous clusters (7, 9, 10, 11, and 12) that
have been integrated into this level, too. Examples include iron and steel bars, crude
minerals, articles of textile fabrics, optical instruments, and electro-diagnostic apparatus.
Level Ixv--lndustries competing on behalf of their "low cost and low price "position, which
perform at least "modestly" in terms of export volumes but "weak" in terms of export prices:
Cluster 17 covers industries which maintain an average competitive position on international
markets mainly by means of their "low cost and low price" position. While market shares lie
modestly above average and trade specialization about average, the standardized values for
the price-dependent variables are distinctly negative. Examples include tubes of iron and
steel, plates of plastic, paper and paperboard (uncut), ball bearings, agricultural machinery,
textile yam, and musical instruments.
Level Ilxv--"Good" performer, mainly in terms of market shares: Cluster 19 is characterized
by market shares that lie well above average and a degree of trade specialization that is near
average performance. The price-dependent variables, again, are modestly above average in
most cases. The small and singular cluster 2 has been included at this level for the sake of
simplicity. Among others, tools, food-processing machines, fruit and vegetable juices, cotton
fabrics, footwear, furniture, clay construction materials, and mineral manufactures belong
to this level.
Level III-- "Champions" of industrial competitiveness, which show high performance in terms
of quantity- as well as quality-based indicators: Level III covers the three relatively
homogeneous clusters 1, 14, and 18, characterized by high values in terms of export volumes
and above or near average price levels. The rest of the product groups contained in this
performance level (clusters 4, 5, 5, 8, and 21) is very heterogeneous, but exhibits a common
level of excellence. Comprising 23 cases, this level represents 22.84 percent of total Austrian
exports. Industries belonging to Level III are mainly spread throughout the sectors of
materials and metals, forest products, transport, and textiles (numbers in parentheses give the
according SITC code):
In the area of basic industries, an internationally successful cluster grew out of rich
endowments of wood and covers: simply worked wood (SITC 248), particle boards (634),
wood manufactures (635), and paper and paperboard (642).
Another cluster of successful related and supporting industries includes steam or other
(vapor-generating) boilers (711), manufactures of based metal (699), as well as structures of
iron, steel, or aluminum (691).
8. 3 0 2 INTERNATIONAL ADVANCES IN ECONOMIC RESEARCH
- - Rails and railway track construction materials of iron or steel (677), together with railway
maintenance vehicles (791), form an especially competitive product group in the domain of
public transport.
- - The production of internal combustion piston engines (713) is one of the most successful
areas of Austrian industrial activity. Besides the innovative capacity of some of the Austrian
manufacturers, this extraordinary performance is mainly due to successful transnational links
to the international automobile industry.
- - The crisis-shaken textile industry still plays an important, but seriously diminishing role
in Austrian manufacturing. Particularly successful product groups are man-made fibers for
spinning (276), manufactures of leather and saddleries (612), and knitted and crocheted
fabrics (655), together with tulles, laces, and the like (656).
-- Television receivers (761) are the most successful product group in the electronics
industry. Again, transnational links via foreign ownership are a major determinant of export
performance.
-- Other successful product groups are baby carriages, toys, games, and sporting goods
(894), glassware (665), lighting fixtures and fittings (813), monofilament (583), medicinal
and pharmaceutical products (541), and non-alcoholic beverages (111).
CONCLUSION
Careful examination of the listing above (results are displayed in more detail in Peneder [1994])
leads to the conclusion that national clusters as proposed by Porter--and defined by a strong
network of related and supporting industries at the same time showing above average
performance--are relatively rare in the case of Austria, especially in comparison with other
countries like Germany [van der Linde, 1992] or Switzerland [Borner et al., 1991]. One exception
is the highly competitive wood processing industry, where simply worked wood, particle boards,
wood manufactures, as well as paper, paperboard, and articles of paper form the international
spearheads of a broad national cluster based on the common primary resource and acquired skills.
Another example is located in the sector of public transportation, with the production of rails and
railway track construction materials on the one hand, and railway maintenance vehicles on the
other.
The results also indicate at least two main reasons for the lack of dynamic and successful
national industrial clusters in Austria. First, some of the most successful Austrian product groups
belong to "old" industries going through deep structural crisis, e.g., textiles and, to a lesser extent,
steel production. Their example is a warning as to how successful clusters in the present can form
the crisis-shaken industrial conglomerates of the future. For these industries, many factors directly
affected by their characteristics as clusters (e.g., strong influence on political decision making and
endowment with specialized factors) can inhibit necessary structural change and, therefore, dampen
prospects of overall industrial development.
In addition, for a small, open economy like Austria, national boundaries can be too narrow to
establish broad cluster relationships. Globalization is an at least equally important factor for
success, as are clusters of related and supporting industries [Rugman and Verbeke, 1992]. Some
of the most successful industries in Austria can be interpreted as parts of bigger transnational
clusters, like the highly competitive production of internal combustion piston engines.
