This paper analyzes the implications of a balanced budget fiscal policy rule for the determinacy of the price level in a cash-in-advance economy under three alternative monetary policy regimes. It shows that, in such stylized models with flexible prices and a period-by-period balanced budget...

In this paper, we characterize conditions under which interest rate feedback rules whereby the nominal interest rate is set as an increasing function of the inflation rate generate multiple equilibria. We show that these conditions depend not only on the fiscal regime (as emphasized in the...

This paper studies the business-cycle fluctuations predicted by a two-sector endogenous-business-cycle model with sector-specific external increasing returns to scale. It focuses on aspects of actual fluctuations that have been identified both as defining features of the business cycle and as...

This paper conducts a quantitative examination of the hypothesis that uncertain duration of currency pegs causes the sharp real appreciations and business cycles that affect chronically countries using fixed exchange rates as an instrument to stop high inflation. Numerical solutions of...

In his seminal 1960 study on the dynamics of alternative exchange rate regimes, Robert Mundell proposed a theory of balance-of-payments crises in which speculators base their actions on the observed holdings of central bank foreign reserves. We examine the quantitative implications of this view...

This paper compares the welfare costs and initial dynamics of three alternative inflation stabilization policies using the staggered price model with imperfect credibility and currency substitution developed by Calvo and Vegh (1990). In addition to the policies analyzed by Calvo and Vegh...

The Tequila Effect hypothesis states that the economic crisis that affected several South American countries in 1995 was caused by an exogenous capital flight triggered by the loss of confidence of foreign investors after the collapse of the Mexican peso in December 1994. I analyze the recent...
