Countercyclical Trade Balance Research Articles

International business cycles: Information matters

We propose a mechanism that explains standard stylized facts in both international macroeconomics and international finance. To do so, we develop a New Keynesian DSGE model with financial frictions à la Bernanke et al. (1999), in which we depart from the full-information rational expectations (FIRE) assumption. The key ingredient is home information bias (HIB) in expectations. While the FIRE model predicts high consumption co-movements, no departure from uncovered interest parity (UIP) and procyclical trade balance, assuming HIB makes the model consistent with the data by producing low consumption correlation, solving the quantity puzzle, generating endogenous departures from the UIP and matching a countercyclical trade balance. The mechanism is empirically validated and shown to be robust to the extent of frictions in the economy.

Asset bubbles and foreign interest rate shocks

We provide an estimated DSGE model of a small open economy with both domestic and international financial market frictions. Firms face credit constraints and trade an intrinsically useless asset. Low foreign interest rates are conducive to bubble formation. An asset bubble provides liquidity and relaxes credit constraints. It provides a powerful amplification and propagation mechanism. Our estimated model based on Bayesian methods explains the high volatilities of consumption and stock prices relative to output, countercyclical trade balance, and procyclical stock prices observed in the Mexican data over the period 1990Q1-2011Q4.

INTERNATIONAL BUSINESS CYCLES IN EMERGING MARKETS

AbstractI document cyclical behavior of real exchange rates (RERs) in emerging and developed economies: stronger RER procyclicality coincides with larger relative volatility of consumption and more countercyclical trade balance. I then reevaluate the sources of fluctuations in emerging economies using an international business cycle model estimated to match the behavior of the RERs. Interest rate shocks, without any frictions, account for most of output fluctuations. This result is driven by imperfect substitution between domestic and foreign goods, which dampens the impact of trend shocks and accentuates the impact of interest rate shocks on output and consumption.

Durable goods, financial frictions, and business cycles in emerging economies

Business cycles in emerging economies display very volatile consumption and strongly countercyclical trade balance. We show that aggregate consumption in these economies is not more volatile than output once durables are accounted for. Then, we present and estimate a real business cycles model for a small open economy that accounts for this empirical observation. Our results show that the role of permanent shocks to aggregate productivity in explaining cyclical fluctuations in emerging economies is considerably lower than previously documented. Moreover, we find that financial frictions are crucial to explain some key business cycle properties of these economies.

News and sovereign default risk in small open economies

This paper builds a unified model of sovereign debt, default risk, and news shocks. News shocks improve the quantitative performance of the sovereign default model in a number of empirically-relevant dimensions. First, with news shocks, not all defaults occur during downturns. Second, the news shocks help account for key differences between developing and more developed economies: as the precision of news improves, the model predicts lower variability of consumption, less countercyclical trade balance and interest rate spreads, as well as a higher level of debt in line with more developed economies. Third, the model captures the hump-shaped relationship between default rates and the precision of news obtained from the data. Finally, the news shocks have a nonmonotonic effect on welfare.

Borrowing constraints and the trade balance–output comovement

The countercyclical trade balance ratio is among the key stylized facts about open economies. The magnitude of the correlation between the trade balance and output, however, differs from country to country. In particular, the trade balance ratio is more negatively correlated with output in emerging economies than in developed economies, suggesting that the trade balance is more sensitive to output changes in the former than in the latter. This paper explores whether this difference is caused by international borrowing constraints imposed on emerging economies.By modeling borrowing constraints as conditional on macroeconomic performance, this paper shows that when there is a positive shock takes place in an emerging economy, GDP increases and the borrowing constraint becomes less binding, resulting in a decreased incentive to accumulate foreign assets. When there is a negative shock, by contrast, GDP falls, and the representative household must increase the trade balance to avoid possible binding borrowing constraints.

Dissecting the Dynamics of the US Trade Balance in an Estimated Equilibrium Model

In an estimated two-country DSGE model, we find that shocks to the marginal efficiency of investment account for more than half of the forecast variance of cyclical fluctuations in the US trade balance. Both domestic and foreign marginal efficiency shocks have a substantial impact on the variability of the imbalance. On the other hand, while traditional technology shocks can generate counter-cyclical trade balance dynamics, they matter very little for the overall forecast variance.

A dynamic small open economy model with involuntary unemployment

Abstract It is well known that real business cycle small open economy (SOE) models rely on Greenwood, Hercowitz, and Huffman (1988) preferences to match the countercyclical trade balance observed in open economies, as well as other second moments, while standard preferences à la King, Plosser, and Rebelo (1988) are commonly labelled ‘ineffective,’ owing to their inability to yield the countercyclical trade balance. In this paper, I show that an SOE model with standard preferences and ‘involuntary’ unemployment with efficient risk sharing can obtain a countercyclical trade balance and match main empirical regularities in small open economies.

Emerging market business cycles: Learning about the trend

Emerging market business cycles feature a higher variability of consumption relative to output and a strongly countercyclical trade balance. An equilibrium business cycle model in which agents learn to distinguish between the permanent and transitory components of total factor productivity shocks using the Kalman filter accounts for these features. Calibrated to Mexico, the model accounts for the behavior of consumption and the trade balance for a wide range of variability and persistence of permanent shocks relative to transitory shocks. Estimation for Mexico and Canada suggests more severe informational frictions in emerging markets than in developed economies.

News and Sovereign Default Risk in Small Open Economies

This paper builds a model of sovereign debt in which default risk, interest rates, and debt depend not only on current fundamentals but also on news about future fundamentals. News shocks affect equilibrium outcomes because they contain information about the future ability of the government to repay its debt. First, in the model with news shocks not all defaults occur in bad times, bringing the model closer to the data. Second, the news shocks help account for key differences between emerging markets and developed economies: as the precision of the news improves the model predicts lower variability of consumption, less countercyclical trade balance and interest rate spreads, as well as a higher level of debt more in line with the characteristics of developed economies. Finally, the model also captures the hump-shaped relationship between default rates and the precision of news obtained from the data.

The Complex Dynamics of Real Exchange Rates with Countercyclical Balance of Trade

We extend Dornbusch's (1973) model to determine whether the countercyclical trade balance which is often observed in real business cycle studies can be rationalized and show that the sum of export and import elasticities being less than one is responsible for the complex fluctuation of exchange rates within this exogenous-shock-free framework.

A Quantitative Examination of Current Account Dynamics in Equilibrium Models of Barter Economies

This paper provides a numerical analysis of an intertemporal equilibrium model of a small open, barter economy that is subject to random shocks affecting endowments, the terms of trade, and the real interest rate. Equilibrium stochastic processes for macroeconomic aggregates are computed and their properties are compared with observed stylized facts. The model mimics the Harberger-Laursen-Metzler effect, but cannot account for a countercyclical trade balance, the variability of the real exchange rate, and the income elasticity of imports. The results also show that the correlation between the trade balance and the terms of trade, given incomplete insurance markets, is sensitive to changes in preference parameters and in the persistence of exogenous shocks.
