This paper provides empirical evidence on the adjustment dynamics of the US net foreign liabilities, net output and consumption. We use empirical techniques that allow us to quantify the relative importance of permanent and transitory innovations. We find that transitory shocks contribute...

This paper provides instrumental variables estimates of the response of aggregate private consumption to transitory output shocks in poor countries. To identify exogenous, unanticipated, idiosyncratic and transitory variations in national output we use year-to-year variations in rainfall as an...

The surge in the German current account surplus in the 2000s is often interpreted as the result of efficiency-enhancing structural reforms, especially in the labor market. However, this interpretation is puzzling because the growth rate of the German economy has been one of the lowest in the...

We identify the groups of countries where international risk-sharing opportunities are most attractive. We show that the bulk of risk-sharing gains can be achieved in groups consisting of as few as seven members, and that further marginal benefits quickly become negligible. For many such small...

Before the crisis, there were strong arguments for reducing global imbalances. As a result of the crisis, there have been significant changes in saving and investment patterns across the world and imbalances have narrowed considerably. Does this mean that imbalances are a problem of the past?...

This paper provides a survey of recent growth models that attempt to explain the cross-country diversity in rates of economic growth. It shows that these models can only generate differences in growth rates in the absence of international capital markets. With free international capital mobility...

We examine optimal policy in a two-country model with uncertainty and learning, where monetary policy actions affect the real economy through the real exchange rate channel. Our results show that whether policy should be cautious or activist depends on the size of one country relative to...

In this Paper we study the competitive equilibria of a two-country endogenous growth model in which the source of growth is the linearity of technology in reproducible inputs. We begin by showing that in a model with no externalities there is a unique equilibrium; however, there are multiple...

A small open economy model is presented, which allows explicit treatment of uncertainty and its effects on macroeconomic behaviour. Inflation targeting is compared to the welfare maximizing monetary rule and to a fixed nominal exchange rate. It is found that flexible inflation targeting produces...
