I study the implications of productivity shocks in a model where agents observe the aggregate level of productivity but not its permanent and transitory components separately. The model`s predictions under learning differ substantially from those under full information and are in line with...

Financially closed economies insure themselves against current-account shocks using international reserves. We characterize the optimal management of reserves using an open-economy model of precautionary savings and emphasize several results. First, the welfare-based opportunity cost of reserves...

This paper introduces a tractable capital market friction mechanism that allows a break of the parity between domestic and external interest rates and generates a gradual evolution of capital stock and other macroeconomic variables--in contrast to the instantaneous convergence found in models...

This paper presents a general approximation method for characterizing time-varying equilibrium portfolios in a two-country dynamic general equilibrium model. The method can be easily adapted to most dynamic general equilibrium models, it applies to environments in which markets are complete or...

This paper analyzes the appropriate choice of an exchange rate regime in agricultural commodity-exporting economies. In an open economy model that incorporates key structural characteristics of agricultural commodity exporters including dual labor markets, the benefits of exchange rate...

We develop an extension of the open economy New Keynesian model in which agents are boundedly rational à la Gabaix (2020). Our setup nests rational expectations (RE) as a special case and it can successfully mitigate many “puzzling” aspects of the relationship between exchange rates and...

This paper investigates whether banking crises are associated with declines in bilateral exports. We first develop a simple open economy model in which banking crises translate into negative liquidity shocks, leading to collapses in exports through supply-side and demand-side shocks. We then...

This paper investigates what factors affect the duration of sudden stops in capital flows using quarterly data for a large panel of countries. We find that countries with floating exchange rate regimes tend to experience shorter sudden stop episodes and that fixed exchange rate regimes are...

Existing studies on the downward trend in the labor share of income mostly focus on changeswithin individual countries. I document, however, that half of the global decline in the laborshare of income can be traced to the relocation of activities between countries. I develop atwo-country model...

Superficial examination of aggregate gross cross-border capital inflow data suggests that therewas no substitution between portfolio inflows and bank loans in recent years. However, ournovel analysis of disaggregate inflows (both by types of instrument and borrower) showsinteresting...
