In this paper, we first introduce investment-specific technology (IST) shocks to an otherwise standard international real business cycle model and show that a thoughtful calibration of them along the lines of Raffo (2009) successfully addresses the quantity, international comovement,...

A puzzle in international macroeconomics is that observed real exchange rates are highly volatile. Standard international real business cycle (IRBC) models cannot reproduce this fact. We show that total factor productivity processes for the United States and the rest of the world are...

Existing DSGE models are not able to reproduce the observed influence of international business cycles on small open economies. We construct a two-sector New Keynesian model to address this puzzle. The set-up takes into account intermediate trade and producer heterogeneity, where goods and...

This paper presents a model yielding testable implications concerning the long-run co-movements of real exchange rates, relative productivity, the trade balance and terms of trade. Countries with higher productivity, trade deficits or improved terms of trade are found to have more appreciated...

Current business cycle models systematically underestimate the correlation between consumption and investment. One reason for this failure is that a positive investment-specific technology shock generally induces a negative consumption response. The objective of this paper is to investigate...

In this paper we study the transmission for capital depreciation shocks. The existing literature in the Real Business Cycle tradition has concluded that these shocks are irrelevant for business cycle fluctuations. We show that these shocks are potentially important drivers of aggregate...

We apply Diebold-Yilmaz spillover index methodology to monthly industrial production indices to study business cycle interdependence among G-6 industrialized countries since 1958. The business cycle spillover index fluctuates substantially over time, increasing especially after the 1973-75,...

It is commonplace to link neoclassical economics to 18th- or 19th-century physics and its notion of equilibrium, of a pendulum once disturbed eventually coming to rest. Likewise, an economy subjected to an exogenous shock seeks equilibrium through the stabilizing market forces unleashed by the...

Credit constraints that link a private agent’s debt to market-determined prices embody a credit externality that drives a wedge between competitive and constrained socially optimal equilibria, inducing private agents to overborrow. The externality arises because agents fail to internalize the...

The creation of the Economic and Monetary Union (EMU) has not brought significant gains to the Portuguese economy in terms of real convergence with wealthier eurozone countries. We analyze the causes of the underperformance of the Portuguese economy in the last decade, discuss its growth...
