Fiat money contains the seeds of its own destruction. It has no intrinsic value and, yet, it can be exchanged for valuable consumption and production goods. As Hahn (1965) shows, this situation puts fiat money's market value or liquidity premium at the brink of collapse. In this paper I will...

The paper examines the robustness of Interest Rate Rules, IRRs, in the context of an imperfectly credible stabilization program, closely following the format of much of the literature in open-economy models, e.g., Calvo and Végh (1993 and 1999). A basic result is that IRRs, like Exchange Rate...

This paper studies optimal fiscal policy in an economy where heterogeneous agents with uncertain lifetimes coexist. We show that some plausible social welfare functions lead to time-inconsistent optimal plans, and we suggest restrictions on social preferences that avoid the problem. The...

This note is motivated by trying to understand the macroeconomic implications of assuming that periods of financial bonanza and turmoil are driven by financial innovation and collapse in line with the "bank run" literature of the Diamond-Dybvig (1983) variety. Bypassing a host of important but,...

collapse and recovery phase of output collapses that coincide with systemic sudden stops, defined as periods of skyrocketing aggregate bond spreads and large capital flow reversals. Our findings indicate the presence of a very similar pattern across different episodes: output recovers with...

The paper discusses a model in which growth is a negative function of fiscal burden. Moreover, growth discontinuously switches from high to low as fiscal burden reaches a critical level. Growth collapse is associated with a Sudden Stop of capital inflows, real depreciation and a drop in output...

High and persistent inflation has been one of the distinguishing macroeconomic characteristics of many developing countries since the end of World War II. Countries afflicted by chronic inflation, however, have not taken their fate lightly and have engaged in repeated stabilization attempts....

We develop a framework to study the effects of policies of uncertain duration on consumption dynamics under both complete and incomplete markets. We focus on the dynamic implications of market incompleteness, specifically on the lack of state-contingent bonds. Two policies are considered: pure...

This paper identifies obstacles hindering the transformation of centrally-planned economies (CPEs) into well-functioning market economies. The analysis is motivated by the recent experience with economic transformation and restructuring in Eastern Europe and the U.S.S.R. The economic system in...

This paper deals with the early stages of transformation of centrally-planned economies (CBEs) into market economies during which expectations playa key role. It focuses on the transitional phase during which the economy is not any more a CPE but has not yet become a market economy. During this...
