This paper examines the effect of volatility on the costs and benefits of financial market integration. The basic framework combines the costly state verification model and the contract enforceability approach. The welfare effects of financial market integration are assessed by comparing welfare...

This paper studies the welfare effects of financial integration in the presence of moral hazard. Entrepreneurs face a trade off between risk and return. Banks may mitigate the resultant excessive risk by costly monitoring, where greater risk reduction requires more resources devoted to risk...

This paper evaluates the welfare implications of privatization in emerging market economies, in countries where policies are determined by the median voter. We show that privatization may lead to large efficiency gains by changing the menu of taxes. We illustrate this point with two examples....

We define and study transparency, credibility, and reputation in a model where the central bank's characteristics are unobservable to the private sector and are inferred from the policy outcome. A low-credibility bank optimally conducts a more inflationary policy than a high-credibility bank, in...

This paper interprets contagion effects as a perceived increase (triggered by events occurring elsewhere) in the volatility of aggregate shocks impinging on the domestic economy. The implications of this approach are analyzed in a model with two types of credit market imperfections: domestic...

This paper revisits the Home Bias Puzzle -- the relatively low interna- tional diversification of portfolios. We suggest that part of the diversifi- cation puzzle may be due to reliance on the conventional CAPM model as the benchmark predicting patterns of diversification. We compare the asset...

Previous analysis of the implementation of inflation targeting is extended to monetary policy responses to different shocks, consequences of model uncertainty, effects of interest rate smoothing and stabilization, a comparison with nominal GDP targeting, and implications of forward-looking...

This paper studies the effect of policy uncertainty on the formation of new activities in Romer's (1994) type of an economy, where productivity of labor increases with the number of capital goods. Adding a new capital good requires a capital specific set-up cost, invested prior to using the...

Inflation targeting is shown to imply inflation forecast targeting: the central bank's inflation forecast becomes an explicit intermediate target. Inflation forecast targeting simplifies both implementation and monitoring of monetary policy. The weight on output stabilization determines how...
