This paper provides a new benchmark for the analysis of the international diversification puzzle in a tractable new open economy macroeconomic model. Building on Cole and Obstfeld (1991) and Heathcote and Perri (2009), this model specifies an equilibrium model of perfect risk sharing in...

This paper focuses on the trade-off faced by governments in deciding the allocation of public expenditures between productivity-enhancing public infrastructures and utility-enhancing public consumption in a two-country model. The results show that a permanent increase in the domestic stock of...

This paper revisits optimal monetary policy in open economies, in particular, focusing on the noncooperative policy game under local currency pricing in a two-country dynamic stochastic general equilibrium model. We first derive the quadratic loss functions which noncooperative policy makers aim...

In this paper, we describe a new multi-country open economy SDGE model named SIGMA that we have developed as a quantitative tool for policy analysis. We compare SIGMA's implications to those of an estimated large-scale econometric policy model (the FRB/Global model) for an array of shocks that...

The empirical literature on border effects suggests that national borders substantially reduce the level of economic transactions. This paper adds another piece of evidence to the significance of border effects by applying a new data set which is completely independent of the data sets of...

This paper discusses whether the integration of international financial markets affects business cycle fluctuations. In the framework of a new open economy macro-model, we show that the link between financial openness and business cycle volatility depends on the nature of the underlying shock....
