Motivation

Global reach of �nancial crisis with high degree ofheterogeneity across countries and regionsWhat are transmission mechanisms?Liquidity shocks

"liquidity squeeze" in credit markets and esp. inter-bankmarketscollapse or near-collapse of �nancial institutionsmassive central bank interventions, incl. cross-border throughswap lines

Pricing of risk & risk appetitehigh leverage of �nancial institutions, though not in EMEsdeleveraging and "�ight-to-safety" phenomena, esp. out ofEMEs; into US treasuries

Real economy shocksde-coupling vs re-couplingcollapse in trade, esp. for more open EMEs

Motivation

First step: Understanding the transmission mechanism

How does the transmission of shocks di¤er across economies?Has the transmission mechanism changed in the crisis?

Second step: Explaining the heterogeneity in the globaltransmission

Methodology

Challenge of identi�cation of liqudity shocks, risk shocks andreal activity shocks

Financial market perspective

response of money markets as proxy for impact on �nancialconditionsresponse of equity markets as proxy for impact on real economy

Global VAR (in�nite-dimensional VARs) of Chudik andPesaran (2009, 2010) allows addressing:

large dimension of VAR - for 26 economies - via concept ofneighborhood e¤ectsall variables treated as endogeneousrestrictions allow for rich spatial and temporal interactionsamong variablesidenti�cation of various shocks, with additional sign restrictionsdistinguish US shocks from shocks to other economies

Bayesian Averaging of Classical Estimates (BACE) approach(Sala-i-Martin et al. 2004)

1 During tranquil periods:

real and �nancial exposure to US more relevant forunderstanding heterogeneity in transmission of US shocks

2 During crisis:

domestic fundamentals, risk and quality of institutions morerelevante.g. FX reserves, sovereign country ratingreal and �nancial exposure less relevant

Literature �Methodology

The methodological approach of the paper links to a broadliterature focusing on Global VAR (GVAR) models.

GVAR was proposed by Pesaran, Schuermann and Weiner(2004). Since then, it has been developed further and used invarious applications (Pesaran et al., 2006, Dees et al., 2007,Pesaran, Smith and Smith, 2007, among others)

Methodological foundations for the speci�cation of countrymodels were developed recently by Chudik and Pesaran (2010)and later extended by Pesaran and Chudik (2010) to allow fordominant units.

Introduction Methodology and Data Estimation results Analysis of cross-country di¤erences Conclusions

Methodology

We follow strategy of Global VAR literature (2 steps):1 Estimation of country-speci�c models of small dimension2 Solving estimated country models in one large Global VAR

We follow Chudik and Pesaran (2010) and Pesaran andChudik (2010) to design individual country models.

Our starting point is the following high-dimensional VARmodel augmented with common factors,

xt = α+Φxt�1 + Γft + ut , and ut = Rεt , (1)

where Φ is a large k � k matrix of coe¢ cients,ut = (u01t , ...,u

0Nt )

0 is an k � 1 vector of reduced form errors,ft is m� 1 vector of (strong) unobserved common factors,and Γ is the corresponding k �m matrix of factor loadings.

Page 10: The Role of Liquidity, Risk and Economic Activity in the ...ec.europa.eu/economy_finance/events/2010/20100723...The Role of Liquidity, Risk and Economic Activity in the Global Transmission

Introduction Methodology and Data Estimation results Analysis of cross-country di¤erences Conclusions

All coe¢ cients in system (1) cannot be estimated due to curseof dimensionality (large number of endogenous variables).

Pesaran and Chudik propose economically intuitive solution tothe curse of dimensionality based on concept of neighborhoode¤ects.

We are very generous on the possibilities of spatio-temporallinkagesWe allow for US dominance in �nancial markets, other sourcesof strong cross section dependence besides the US in�uence,and local neighborhood e¤ects.

Our methodology treats all variables as endogenous. We donot rely on some of the restrictive assumptions in factormodel literature (e.g. the assumption that unboundedeigenvalues cannot rise at a rate slower than N).

Identi�cation of global shocks

Global shocks enter the vector residuals in the US marginalmodel (featuring domestic variables and foreign cross sectionaverages), but additional restrictions are needed if one wantsto distinguish between US and foreign global shocks withnon-US origin

To accomplish this, we suppose that the US shocks come �rst

Within the set of US shocks, we aim to distinguish between aUS macro surprise shock, a stock market shock, an interestrate shock, a risk aversion shock and a liquidity shock. Wecombine sign restriction and partial ordering approaches toachieve identi�cation

Partial ordering of US shocks: (Group 1) a US macro surpriseshock, (Group 2) risk aversion shock and a liquidity shock, and(Group 3) a stock market shock and an interest rate shock

Analysis of cross-country di¤erences in the transmission ofshocks - Methodology

To shed light on the cross-section heterogeneity in thetransmission of US shocks to the rest of the world, weestimate the following cross-section regression

y (s)i = c (s) +K

∑`=1

β(s)` xi` + ζ

(s)i , for i = 2, ...,N,

where y (s)i is the contemporaneous impact of a US shock s(to US macro news, VIX, TED, US money market or US stockmarket) on the stock market or the money market of countryi , and xi` for i = 2, ...,N and ` = 1, 2, ...,K is the set of Kfundamentals speci�c to country i .

Page 30: The Role of Liquidity, Risk and Economic Activity in the ...ec.europa.eu/economy_finance/events/2010/20100723...The Role of Liquidity, Risk and Economic Activity in the Global Transmission

Introduction Methodology and Data Estimation results Analysis of cross-country di¤erences Conclusions

We have relatively limited number of countries, yet thepotential set of country fundamentals is large (We havecompiled K = 14 fundamentals)

Therefore we follow Bayesian Averaging of Classical Estimates(BACE) approach of Sala-i-Martin et. al (2004), which wasoriginally developed to analyze determinants of growth.

This approach combines the averaging of estimates acrossmodels estimated by classical ordinary least squares (OLS)and is particularly useful for understanding which of the largeset of determinants (if any) might play a role empirically.

Conclusions

Focus on global transmission of �nancial crisis, acrossadvanced economies and EMEs

Global VAR approach; 26 economies and 2 �nancial marketsegments

Objective to better understand role of three distinct types ofshocks as culprits:

a tightening in liquidity conditions and credit markets �>mattered more for advanced, esp. in Europea severe re-pricing of risk and �ight of investors into safe assetclasses �> EMEs, esp. CEECa strong and synchronous collapse of economic activity �>EMEs, esp. Latin America & CEEC

Factors accounting for cross-country di¤erences

Implications

Complexity of global transmission of the crisis; cannot bereduced to a single dimension

Countries were not innocent bystanders, but severity oftransmission not only related to real and �nancial exposure...

But to a substantial extent also to domestic macroeconomicfundamentals and institutions

Role for economic policy, though controversy about speci�cs(e.g. self-insurance/reserves vs. institutions)
