This paper examines policy responses to exchange-rate movements in a simple model of an open economy. The optimal response of monetary policy to an exchange-rate change depends on the source of the change: on whether the underlying shock is a shift in capital flows, manufactured exports, or...

A considerable literature has examined the causes, consequences, and policy responses to surges in international capital flows. A related strand of papers has attempted to catalog current account reversals and capital account "sudden stops." This paper offers an encompassing approach with an...

Based on a sample of 104 countries, we document four key stylized facts regarding the interaction between capital flows, fiscal policy, and monetary policy. First, net capital inflows are procyclical (i.e., external borrowing increases in good times and falls in bad times) in most OECD and...

Using a human capital based growth model, we show the essential role of labor mobility and cross-country tax harmonization in equalizing income levels of countries that start off from different initial income positions. Knowledge spillovers cum labor mobility are the driving forces behind the...

This paper considers the effects of fiscal and financial policy on economic growth in open and closed economies, when human capital formation by young households is constrained by the illiquidity of human wealth. Both endogenous and exogenous growth versions of the basic OLG model are analyzed....

This lecture examines the effects of tax policy and social security retirement benefits on capital accumulation and economic welfare.

This paper describes the challenges of globalization in terms of the logic underpinning four distinct policy constraints or "trilemmas" and their interrelationship; in particular the disturbances that arise from capital flows and the difficulties of adjusting monetary policies to a global...
