China’s Emergence in the World Economy and Business Cycles in Latin America

This paper investigates how changes in trade linkages between China, Latin America, and the rest of the world have altered the transmission of international business cycles to Latin America. Evidence based on a GVAR model for five large Latin American economies shows that the long-term impact of a China GDP shock on the typical Latin American economy has increased by three times since the mid-1990s, while the long-term impact of a US GDP shock has halved, while the transmission of shocks to Latin America and the rest of emerging Asia GDP (excluding China and India) has not changed. These changes owe more changes in China’s impact on Latin America’s traditional and largest trading partners than to increased direct bilateral trade linkages boosted by the decade-long commodity price boom. These findings have important implications for both Latin America and the international business cycle.

GEM; A New International Macroeconomic Model

Over the past two years, the IMF staff has been developing a new multicountry macroeconomic model called the Global Economy Model (GEM). This paper explains why such a model is needed, how GEM differs from its predecessor model, and how the new features of the model can improve the IMF’s policy analysis. The paper is aimed at a general audience and avoids technical detail. It outlines the motivation, structure, strengths, and limitations of the model; examines three simulation exercises that have been completed; and discusses the future path of GEM.

Retail Bank Interest Rate Pass-Through: Is Chile Atypical?

This paper investigates empirically the pass-through of money market interest rates to retail banking interest rates in Chile, the United States, Canada, Australia, New Zealand, and five European countries. Overall, Chile’s pass-through does not appear atypical. Based on a standard errorcorrection model, we find that, as in most countries considered, Chile’s measured pass-through is incomplete. But Chile’s pass-through is also faster than in many other countries considered and is comparable to that in the United States. While we find no significant evidence of asymmetry in Chile’s pass-through across states of the interest rate or monetary policy cycle, we do find some evidence of parameter instability, around the time of the Asian and Russian crises. However, we do not find evidence that the switch to a more flexible exchange rate regime in 1999 and the “nominalization” of Chile’s interest rate targets in 2001 have affected significantly the pass-through process.

Capital Controls or Exchange Rate Policy? A Pecuniary Externality Perspective

In the aftermath of the global financial crisis, a new policy paradigm has emerged in which old-fashioned policies such as capital controls and other government distortions have become part of the standard policy toolkit (the so-called macro-prudential policies). On the wave of this seemingly unanimous policy consensus, a new strand of theoretical literature contends that capital controls are welfare enhancing and can be justified rigorously because of second-best considerations. Within the same theoretical framework adopted in this fast-growing literature, we show that a credible commitment to support the exchange rate in crisis times always welfare-dominates prudential capital controls as it can achieve the first best unconstrained allocation. In this benchmark economy, prudential capital controls are optimal only when the set of policy tools is restricted so that they are the only policy instrument available.

Global Liquidity, House Prices and the Macroeconomy: Evidence from Advanced and Emerging Economies

In this paper we first compare house price cycles in advanced and emerging economies using a new quarterly house price data set covering the period 1990-2012. We find that house prices in emerging economies grow faster, are more volatile, less persistent and less synchronised across countries than in advanced economies. We also find that they correlate with capital flows more closely than in advanced economies. We then condition the analysis on an exogenous change to a particular component of capital flows: global liquidity, broadly understood as a proxy for the international supply of credit. We identify this shock by aggregating bank-to-bank cross-border credit flows and by using the external instrumental variable approach introduced by Stock and Watson and Mertens and Ravn. We find that in emerging markets a global liquidity shock has a much stronger impact on house prices and consumption than in advanced economies. We finally show that holding house prices constant in response to this shock tends to dampen its effects on consumption in both advanced and emerging economies, but possibly through different channels: in advanced economies by boosting the value of housing collateral and hence supporting domestic borrowing; in emerging markets, by appreciating the exchange rate and hence supporting the international borrowing capacity of the economy.

Optimal Policy for Macro-Financial Stability

In this paper we study whether policy makers should wait to intervene until a financial crisis strikes or rather act in a preemptive manner. We study this question in a relatively simple dynamic stochastic general equilibrium model in which crises are endogenous events induced by the presence of an occasionally binding borrowing constraint as in Mendoza (2010). First, we show that the same set of taxes that replicates the constrained social planner allocation could be used optimally by a Ramsey planner to achieve the first best unconstrained equilibrium: in both cases without any precautionary intervention. Second, we show that the extent to which policymakers should intervene in a preemptive manner depends critically on the set of policy tools available and what these instruments can achieve when a crisis strikes. For example, in the context of our model, we find that, if the policy tools is constrained so that the first best cannot be achieved and the policy maker has access to only one tax instrument, it is always desirable to intervene before the crisis regardless of the instrument used. If however the policy maker has access to two instruments, it is optimal to act only during crisis times. Third and finally, we propose a computational algorithm to solve Markov-Perfect optimal policy for problems in which the policy function is not differentiable.

Uncertainty and Economic Activity: A Global Perspective

The 2007-2008 global financial crisis and the subsequent anemic recovery have rekindled academic interest in quantifying the impact of uncertainty on macroeconomic dynamics based on the premise that uncertainty causes economic activity to slow down and contract. In this paper, we study the interrelation between financial markets volatility and economic activity assuming that both variables are driven by the same set of unobserved common factors. We further assume that these common factors affect volatility and economic activity with a time lag of at least a quarter. Under these assumptions, we show analytically that volatility is forward looking and that the output equation of a typical VAR estimated in the literature is mis-specified as least squares estimates of this equation are inconsistent. Empirically, we document a statistically significant and economically sizable impact of future output growth on current volatility, and no effect of volatility shocks on business cycles, over and above those driven by the common factors. We interpret this evidence as suggesting that volatility is a symptom rather than a cause of economic instability.

Global Imbalances: The Role of Emerging Asia

This paper investigates the role played by emerging Asia in the emergence and evolution of the global trade imbalances. Based on simulations in a general equilibrium model of the world economy, we find that a productivity slowdown in the non-tradable sector of these economies in the second half of the 1990s fits regional macroeconomic developments relatively well, but has limited spillover effect to the United States trade balance. In contrast, an increase in the desired level of emerging Asia net foreign assets starting in 2001 not only fits regional developments relatively well, but also has a significant spillover effect to the United States.

Bayesian VARs: A Survey of the Recent Literature with an Application to the European Monetary System

This paper reviews recent advances in the specification and estimation of Bayesian Vector Autoregressive models (BVARs). After describing the Bayesian principle of estimation, we first present the methodology originally developed by Litterman (1986) and Doan et al. (1984) and review alternative priors. We then discuss extensions of the basic model and address issues in forecasting and structural analysis. An application to the estimation of a system of time-varying reaction functions for four European central banks under the European Monetary System (EMS) illustrates how some of the results previously presented may be applied in practice.

The Domestic and Global Impact of Japan's Policies for Growth

Japan is facing a sizable fiscal imbalance against a backdrop of weak trend growth and growing external imbalances in the world economy. This paper examines the possible impact of fiscal adjustment and productivity-enhancing structural reforms on the Japanese and world economies. Simulation results indicate that these could reduce substantially Japans fiscal imbalance with only limited spillovers to the rest of the world. Specifically, faster productivity growth would help lower Japans debt and limit the tendency of fiscal consolidation to increase the external surplus. In fact, very rapid productivity growth could potentially lead to a decline in Japans external surplus and thereby have a positive effect on global imbalance. The modest extent of the spillovers to the rest of the world reflect the small size of the shocks and the diminished size of Japan in the world economy.
