In this paper we reconcile two opposing views about the elasticity of intertemporal substitution in consumption (EIS). Empirical studies using aggregate consumption data typically find that the EIS is close to zero (Hall, 1988). Calibrated models designed to match growth and fluctuations facts...

The paper discusses and revisits some of the most popular stories behind the 2001 financial crisis in Argentina, i.e. the prolonged overvaluation of the peso owing to the Currency Board arrangement, the lack of fiscal adjustment, and the negative external environment which triggered a “sudden...

This paper provides some further tests for the proposition that a larger public sector leads to smaller output volatility. Both Gali and Fatas & Mihov have provided some evidence which appears to support this proposition. Their evidence is, however, based on a relatively small sample of...

This paper examines the impact of macroeconomic policy shocks in a Real- Business-Cycle Model with money. In addition to technology shocks, I include government consumption, government investment, tax rate and monetary policy as sources of random disturbances. Money is introduced in a...

This paper reexamines the relationship between financial market imperfections and economic instability. I present a model in which financial accelerator effects come from adverse selection in credit markets. Unlike other models of the financial accelerator, the model I present has the potential...

Theoretical studies have shown that under unorthodox assumptions on preferences and production technologies, collateral constraints can act as a powerful amplification and propagation mechanism of exogenous shocks. We investigate whether or not this result hold under more standard assumptions....

This paper studies the role of collateral constraints in transforming small monetary shocks into large persistent output fluctuations. We do this by introducing money in the heterogeneous-agent real economy of Kiyotaki and Moore (1997). Money enters in a cash-in-advance constraint and is...

Over the last decade, research has shown that financing constraints have an important impact on many aspects of firm behavior and aggregate fluctuations. This paper undertakes a critical comparison of the three main financing constraint hypotheses- -the bank lending, collateral, and internal...

This paper introduces an upgraded version of MSVARlib, a Gauss and Ox- Gauss compliant library, focusing on Multivariate Markov Switching Regressions in their most general specification. This new set of procedures allows to estimate, through classical optimization methods, models belonging to...

I use numerical methods to test for the presence of one-time structural breaks in the conditional variance of nominal interest rate spreads in four European countries over a period of eleven years (Jan 1988 to Dec 1998). I start with an intuitive approach consisting of a sequence of breakpoint...
