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 explores the effect of news shocks on the current account and other macroeconomic variables using worldwide giant oil discoveries as a directly observable measure of news shocks about future output - the delay between a discovery and production is on average 4 to 6 years. We first...

This paper evaluates the global welfare impact of China's trade integration and technological change in a quantitative Ricardian-Heckscher-Ohlin model implemented on 75 countries. We simulate two alternative productivity growth scenarios: a "balanced" one in which China's productivity grows at...

This paper explains in detail the construction of series for productivity in the traded and nontraded sectors for a panel of 56 countries spanning 1989–2012. The level of productivity in each sector is defined as real value added per worker in constant 2005 Purchasing Power Parity (PPP) U.S....

This paper studies the linkage between structural coherence and economic growth. Structural coherence is defined as the degree that a country's industrial structure optimally reflects its factor endowment fundamentals. The paper found that at least for the overall capital, the shares of capital...

Keller (1998) reexamines Coe and Helpman`s (1995) analysis of international R&D spillovers focusing on the weights used to define the foreign R&D capital stock. Keller creates random weights and shows that they give rise to positive estimates of international R&D spillovers, casting doubts on...

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 develops a small open economy model where global and domestic liquidity is intermediated to the corporate sector through two financial processes. Investment banks intermediate cross-border credit through interlinked debt contracts to entrepreneurs and commercial banks intermediate...

We develop an open economy New Keynesian Model with foreign exchange intervention inthe presence of a financial accelerator mechanism. We obtain closed-form solutions for theoptimal interest rate policy and FX intervention under discretionary policy, in the face ofshocks to risk appetite in...
