In this paper we analyze empirically the most important implications of two family political economy models of inflation: the "myopic? government approach and the "weak" government approach. In myopic government models inflation is the deliberate outcome of politicians strategic behavior, while...

Financial crises in emerging market countries appear to be very costly: both output and a host of partial welfare indicators decline dramatically. The magnitude of these costs is puzzling both from an accounting perspective -- factor usage does not decline as much as output, resulting in large...

We construct a simple model in which high inflation imposes welfare costs because it affects the ability of the financial sector to screen between high and low cost producers. Consumers search for a low price and inflation reduces the incentives to search, resulting in an increase in the demand...

We study the interplay of optimal ex-ante (macroprudential) and ex-post (monetary or fiscal stimulus) measures to respond to systemic financial crises in a tractable model of fire sales. We find that it is generally optimal to use both, rejecting the Greenspan doctrine to only intervene ex post....

The paper analyzes the effects of financial integration on the stability of the banking system. Financial integration allows banks in different regions to smooth local liquidity shocks by borrowing and lending on a world interbank market. We show under which conditions financial integration...

We characterize fiscal and monetary policy in a monetary union with the potential for rollover crises in sovereign debt markets. Member-country fiscal authorities lack commitment to repay their debt and choose fiscal policy independently. A common monetary authority chooses inflation for the...

International financial integration helps to diversify risk but also may increase the trans- mission of crises across countries. We provide a quantitative analysis of this trade-off in a two-country general equilibrium model with endogenous portfolio choice and collateral con- straints....

The paper argues that Lucas overestimates the Friedman-Bailey type of welfare cost of inflation and neglects other important welfare effects. With an alternative interpretation of the non-observability of low interest rates than the one Lucas gave and the introduction of taxes that reduce the...

This paper estimates the efficiency consequences of interactions between nominal tax systems and inflation in open economies. Domestic inflation changes after-tax real interest rates at home and abroad, thereby stimulating international capital movement and influencing domestic and foreign tax...

At a minimum, this paper should serve as a warning against too easy an acceptance of the view that the costs of sustained inflation are small relative to the costs of unemployment. If a temporary reduction in unemployment causes a permanent increase in inflation, the present value of the...
