Motivated by a strong degree of hysteresis in the stock of monetization observed after the end of hyperinflations, I provide a cash-and-credit model in which the use of money exhibits some persistence because individuals can establish long-lasting credit relationships. This feature helps to...

This paper serves two purposes. First, it investigates to what extent a New Keynesian monetary model with the addition of a microfounded, non-Walrasian labor market based on union bargaining is able to replicate key aspects of the business cycle. Second, it explores the influence of this setting...

We examine optimal policy in an open-economy model with uncertainty and learning, where monetary policy actions affect the economy through the real exchange rate channel. Our results show that the degree of caution or activism in optimal policy depends on whether central banks are in coordinated...

Here I consider the dynamics of interest rate processes in the multi-factor model specified in Heath, Jarrow and Morton (1992). Despite its flexibility and theoretical advances, the number of empirical studies using the HJM model remains inadequate, principally because of the difficulty...

The attractiveness of spatial autoregressive models has increased significantly. The awareness of important spatial interactions arose in various fields. In economics, interactions can be due to interdependencies between entities such as states, firms, or consumers. Examples are spatial...

The accuracy of the solution of dynamic general equilibrium models has become a major issue. Recent papers, substituting second order for first order approximations, have shown to obtain significant differences in accuracy. Second order approximations have had some considerable success in...

Recent theoretical work by Cooley and Quadrini (2001) highlight the role of financial frictions in models of firm dynamics. This paper investigates empirically the implications of the Cooley and Quadrini (2001) model for the determinants of firm size dynamics with special emphasis on financial...

Emprical studies of hyperinflations reveal that the rational expectations hypothesis fails to hold. To address this issue, we study a model of hyperinflation and learning in an attempt to better understand the volatility in movements of expectations, money, and prices. The findings surprisingly...

We analyze how strategic asset trading can be used to gain competitive advantage. In the case of electricity markets, companies seek to improve the value of their generating portfolios by acquiring, or selling, power plants. Accordingly, we derive the basic determinants of plant value,...

We provide evidence that higher moments of the relative price distribution improve out-of-sample forecasts of inflation. Further, we show how theoretically consistent higher moments can be calculated by expanding the seminal work by Theil (1967). Results presented here are of direct relevance to...
