This document summarizes a paper that builds economic models to explain the large increase in foreign holdings of local currency emerging market sovereign debt. The paper develops models with limited market participation and different investor types to show how foreign investor entry into local currency bond markets can increase when risk aversion is low. Simulation of the models using interest rate data suggests foreign holdings of local currency debt rose strongly after the Great Recession when developed country rates fell. The paper aims to understand the implications of changing currency composition and investor composition of emerging market government debt.
The slides provide a brief background on foreign loans and investments in the Philippines including foreign direct investments. It also shows some data on these financial inflows
The Civil War in Tajikistan (Tajik: 'Ҷанги шаҳрвандии Тоҷикистон') began in May 1992 when ethnic groups from the Garm and Gorno-Badakhshan regions, which were underrepresented in the ruling elite, rose up against the national government of President Rahmon Nabiyev, in which people from the Leninabad and Kulyab regions dominated. Politically, the discontented groups were represented by liberal democratic reformists[6] and Islamists, who fought together and later organized under the banner of the United Tajik Opposition. By June 1997, from 50,000 to 100,000 people had been killed.

Homework 51)a) the IS curve ln Yt= ln Y(t+1) – (1Ɵ)rtso th.docxadampcarr67227
Homework 5
1)
a) the IS curve: ln Yt= ln Y(t+1) – (1/Ɵ)rt
so the slope is: drt/dyt (is) = -Ɵ/Yt. That means that an increase in Ɵ will result in a steeper curve.
LM curve: Mt/Pt = Yt^(Ɵ/v) (1+rt / rt)^(1/v)
Ln(Mt/Pt) = (Ɵ/v) ln Yt +(1/v)ln(1+rt) – (1/v)ln rt.
0 = (Ɵ/v)(1/Yt)dYt + (1/v)(1/(1+rt)) drt – (1/v)(1/rt)drt.
The slope is: drt/dyt (LM) = (Ɵrt(1+rt))/Yt. That means that an increase in Ɵ will result in a steeper curve.
b) the curve IS is not affected by the value of V. while curve LM shifts upwards, since a decrease in v will result in an increase for the demand for real money.
c) IS is not affected byΓ(.)
optimal money holdings: BΓ’(Mt/Pt) = (it/(1+it)) U’(Ct)
B(Mt/Pt)^(-v) = (it/1+it) Yt^-Ɵ
Mt/Pt= B^(1/v) Yt^(Ɵ/v) (1+rt/rt)^(1/v)
So this means that the LM curve will shift downwards.
2)
a) AC= (PC/)+(αYP/2)i
AC/ = -(PC/^2) + (αYP/2)I = 0
C/^2 = αYi/2
So *=(2C/αYi)^(1/2)
b) average real money holdings:M/P= αY/2
M/P = (αY/2) (2C/αYi)^(1/2)
M/P= (αCY/2i)^(1/2)
Ln(m/p) = (1/2)(lnα+lnY+lnC-ln2-lni)
(1/(M/P))((M/P)/i) = -(1/2)(1/i)
Elasticity of real money with respect to i: ((M/P)/)(i/(M/P)) = -1/2
The elasticity with respect to Y : ((M/P)/Y)(Y/(M/P)) = ½
Average real money holdings increase in Y, and decrease in i.
4)
a)when p is at a level that generates maximum output, LS meets LD.
b) when p is above the level that generates maximum output, will cause unemployment.
7)
a)
b)i)
ii)
iii)
13)
a) the asset has an expected rate of return r. capital gain/loss plus dividends per unit time = rvp. There is no dividends per unit time while searching for the palm tree, and there is b probability per unit time of capital gain of (vc-vp)-c. the difference in the price of the asset is(vc-vp) and –c is what the asset pays, so at the end we have rvp=b(vc-vp-c)
b) there is probability aL that a person will find another person with a coconut and trade with that person and gain u̅. the difference in the price of the asset is (vp-vc). So we end up with
rvp=al(vp-vc+u̅).
c) vp=(rvc/aL)+vc-u̅.
r((rvc/aL )+vc-u̅)= b(vc-(rvc/aL)-vc+u̅-c)
vc(r(r+aL+b))/aL = u̅(r+b)-bc
the value of being in state C: vc= (aL(u̅(r+b)-bc)) / r(r+aL+b)
the value of being in state p: vp= ((u̅(r+b)-bc)/(r+aL+b)) + (aL(u̅(r+b)-bc)/r(r+aL+b)) - u̅
so finally
vc-vp = (bc+u̅aL)/(r+aL+b).
e) vc-vp ≥c
vc-vp = (bc+u̅a(b/a))/(r+a(b/a)+b) = (bc+bu̅)/(r+2b)
(bc+bu̅)/(r+2b) ≥ c
That means that
Bc+bu̅≥c and c(r+2b-b) ≤ bu̅
So finally we have
c≤ bu̅ / (r+b).
f) it is a steady-state equilibrium for no one who finds a tree to climb it for any value of c>0.
Yes there are values of c which there is more than one steady-state equilibrium for 0<c< bu̅/(r+b)
Yes, L = b/a has a higher welfare than L=0. When L=0 people don’t gain any utility since they don’t climb a tree and don’t have a chance to trade with other people and gain a coconut.

"Correlated Volatility Shocks" by Dr. Xiao Qiao, Researcher at SummerHaven In...Quantopian
Commonality in idiosyncratic volatility cannot be completely explained by time-varying volatility. After removing the effects of time-varying volatility, idiosyncratic volatility innovations are still positively correlated. This result suggests correlated volatility shocks contribute to the comovement in idiosyncratic volatility.
Motivated by this fact, we propose the Dynamic Factor Correlation (DFC) model, which fits the data well and captures the cross-sectional correlations in idiosyncratic volatility innovations. We decompose the common factor in idiosyncratic volatility (CIV) of Herskovic et al. (2016) into the volatility innovation factor (VIN) and time-varying volatility factor (TVV). Whereas VIN is associated with strong variation in average returns, TVV is only weakly priced in the cross section
A strategy that takes a long position in the portfolio with the lowest VIN and TVV betas, and a short position in the portfolio with the highest VIN and TVV betas earns average returns of 8.0% per year.
Incomplete-Market Equilibrium with Unhedgeable Fundamentals and Heterogeneous...guasoni
We solve a general equilibrium model of an incomplete market with heterogeneous preferences, identifying first-order and second-order effects. Several long-lived agents with different absolute risk-aversion and discount rates make consumption and investment decisions, borrowing from and lending to each other, and trading a stock that pays a dividend whose growth rate has random fluctuations over time. For small fluctuations, the first-order equilibrium implies no trading in stocks, the existence of a representative agent, predictability of returns, multi-factor asset pricing, and that agents use a few public signals for consumption, borrowing, and lending. At the second-order, agents dynamically trade stocks and no representative agent exist. Instead, both the interest rate and asset prices depend on the dispersion of agents' preferences and their shares of wealth. Dynamic trading arises from agents' intertemporal hedging motive, even in the absence of personal labor income.

Resume
• Real GDP growth slowed down due to problems with access to electricity caused by the destruction of manoeuvrable electricity generation by Russian drones and missiles.
• Exports and imports continued growing due to better logistics through the Ukrainian sea corridor and road. Polish farmers and drivers stopped blocking borders at the end of April.
• In April, both the Tax and Customs Services over-executed the revenue plan. Moreover, the NBU transferred twice the planned profit to the budget.
• The European side approved the Ukraine Plan, which the government adopted to determine indicators for the Ukraine Facility. That approval will allow Ukraine to receive a EUR 1.9 bn loan from the EU in May. At the same time, the EU provided Ukraine with a EUR 1.5 bn loan in April, as the government fulfilled five indicators under the Ukraine Plan.
• The USA has finally approved an aid package for Ukraine, which includes USD 7.8 bn of budget support; however, the conditions and timing of the assistance are still unknown.
• As in March, annual consumer inflation amounted to 3.2% yoy in April.
• At the April monetary policy meeting, the NBU again reduced the key policy rate from 14.5% to 13.5% per annum.
• Over the past four weeks, the hryvnia exchange rate has stabilized in the UAH 39-40 per USD range.

The European Unemployment Puzzle: implications from population agingGRAPE
We study the link between the evolving age structure of the working population and unemployment. We build a large new Keynesian OLG model with a realistic age structure, labor market frictions, sticky prices, and aggregate shocks. Once calibrated to the European economy, we quantify the extent to which demographic changes over the last three decades have contributed to the decline of the unemployment rate. Our findings yield important implications for the future evolution of unemployment given the anticipated further aging of the working population in Europe. We also quantify the implications for optimal monetary policy: lowering inflation volatility becomes less costly in terms of GDP and unemployment volatility, which hints that optimal monetary policy may be more hawkish in an aging society. Finally, our results also propose a partial reversal of the European-US unemployment puzzle due to the fact that the share of young workers is expected to remain robust in the US.

Limited participation and local currency sovereign debt
1. Limited Participation and Local Currency Sovereign Debt
Nicola Borri, LUISS, Rome
Kirill Shakhnov, EIEF, Rome
ADEMU Conference – Toulouse, 4 April 2018
2. Motivation
Large increase in the stock of EM sovereign bonds denominated in local currency
over last 15 years graph graph yields
Local currency ≈ US$4.2 trillions (2016)
Foreign currency ≈ US$900 billions (2016)
Large increase in foreign holdings of local currency EM debt graph graph table
The average share in local currency from ≈ 5% in 2004 to approximately 15% in
2016 (≈ US$600 billions)
Large differences across countries, and over time graph
The average share in foreign currency ≈ 45%
Extremely low government bond rates in developed countries after Great Recession graph
3. Questions
What explains the large increase in foreign holdings of local currency EM
sovereign bonds?
What are the implications of the change in currency composition of EM
government debt and in the shares held by foreign investors?
for EM: better and less risky funding costs?
for foreign investors: better portfolio diversification?
4. This Paper
We lay down a model with limited market participation and different investors
foreign investors are specialized in foreign currency denominated EM debt
local investors are specialized in local currency denominated EM debt
some foreign investors access both markets after paying entry cost
risk-aversion of foreign investors is time-varying and counter-cyclical
5. Main Findings
When risk-aversion is sufficiently low, benefits of investing in foreign markets are
greater than entry costs
The larger the share of foreign investors in the market for local currency bonds,
the higher their sensitivity to global shocks and correlation with foreign currency
bonds
Feeding actual U.S. interest rate data after the Great Recession to the model
results in strong increase in fraction of local currency debt held by foreigners

9. Model: a simplified framework
(1 asset, 1 investor, exchange rate & default risk)
Single risky asset and a single set of ”specialized” investors
Risky asset is a defaultable long-term bond denominated in local currency (LC)
Investors are foreigners with an objective function in foreign currency (FC) (e.g.,
U.S. hedge funds)
Investors have also access to short-term risk-free asset denominated in FC (e.g., a
U.S. T-bill)
10. Model: a simplified framework
(1 asset, 1 investor, exchange rate & default risk)
The risky asset is a portfolio of perpetual bonds with per-period coupon C

26. Endogenous Entry
We now introduce endogenous entry of foreign investors in the market for LC
bonds and time-varying risk tolerance
when generalists invest in the LC asset, they must pay a per period fix cost ψ
specialists in asset B every period can decide whether to become generalists, pay the
fee ψt and invest also in asset A
the entry condition for specialists in B is
∆u ≡ ug
t − us,B
t = ψt (8)
where ug
t is utility for generalists and us,B
t of specialists in B in t
The entry cost is a proxy for transaction costs in order to operate in the local
market and/or development of local financial market
27. Endogenous Entry

B − xAxBcorAB,t
(1 − corAB,t )
where xA are the risk-adjusted return on A and corAB,t the correlation coefficient
between the conditional excess returns on the two assets
28. Time-Varying Risk Aversion
We introduce time-varying risk aversion in a reduce form
we assume that local investors risk-tolerance is constant and equal to ¯τA
the risk-tolerance of foreign investors is instead a function of state variables
τB,t+1 = ¯τB + κ xt (10)
where κ is a vector of loadings on the states
note that τB,t+1 is pre-determined at t and is taken as given by investors in their
portfolio decisions
in empirical estimation we simply assume the only non-zero coefficient of κ is for the
risk-free rate in foreign currency (i.e., τB,t+1 high when interest rate is low)
this could be endogeneized in model with habit preferences when the intertemporal
substitution effect dominates the precautionary saving effect

shocks to the default realization of FC bonds affects also LC bonds when fraction
of generalists is large
shocks to the default realization of LC bonds affects mostly LC bonds, and the
more so the lower the fraction of generalists
37. Entry (II/II)
For a given level of risk tolerance, the benefits of becoming generalists decline
with the share of generalists
For a given level of the share of generalists, the benefits of becoming generalists
increase with the risk tolerance
39. Conclusion
We build a model of partially segmented markets where foreign investors are
specialized in EM bonds in FC and local investors in LC, and foreign investors can
also invest in LC bonds after paying a fee
- for a given fee level, benefits to foreign investors from entering the LC bond market
are larger the lower their risk aversion
- the sensitivity to global shocks of LC bonds is higher the larger the share of foreign
investors in the market for LC bonds
- when foreign investors’ risk aversion is positively correlated to U.S. short-term
interest rates, the model predicts the significant increase in the share of LC bonds
held by foreign investors that we observe in the data after the Great Recession
The model can be used to study counterfactual scenarios, like the effect of the
exit of the Fed from the low interest rate environment

53. Asset Pricing (Standard Model)
If the LOP holds, and investors can form portfolios freely, there exists a SDF Mt+1 that
prices any excess return Re,i
t+1:
Et Mt+1Re,i
t+1 = 0
Assuming that returns and SDF are lognormal, the Euler equation implies
Et (re,i
t+1) = −
covt (mt+1, re,i
t+1)
vart (mt+1)
βi
t
vart (mt+1)
λt
where lower cases denote logs.
If M is an excess return, its market price of risk λ should be equal to its mean as beta is
equal to 1 (no-arbitrage condition).

58. Equilibrium Selection
In a similar framework, GHL show that a linear equilibrium exists only if investors
are sufficiently risk-tolerant (i.e., if τ is large enough)
When investors are sufficiently risk tolerant, there two types of solutions
1. yields are highly sensitive to supply shocks and bonds very risky so that investors
want to be compensated with large returns (i.e., large changes in yields)
2. yields are less sensitive to supply shocks and bonds less risky, so that investors
require smaller returns
Following GHL, we focus on the solution that implies that yields are less sensitive
to changes in their own supply
it is possible to show that the first root is explosive when σ q→∞
back
59. Differences with respect to GHL
1. We assume that both assets are defaultable long-term bonds
2. We introduce exchange rate risk
3. We assume that foreign investors are specialized in FC bonds, and local investors
in LC bonds
4. We assume that generalist investors invest in both markets
5. We introduce endogenous entry in the pool of generalists
6. We assume that foreign investors have time-varying risk aversion tied to the
risk-less U.S. short-term interest rate

In our framework, for each asset
rxi,t+1 − Et [rxi,t+1] = φ t+1
where φ = φA φB contains the factor loadings of each asset on the factor
