We study a rational expectations' competitive equilibrium in a production economy, i.e., a system of prices at which firms' profit maximizing production decisions and individuals' preferred affordable consumption choices equate supply and demand in every market. We derive the equilibrium price...

In this article we define a Recursive Competitive Equilibrium, provide an example and review the related literature. The article is an entry prepared for The New Palgrave: A Dictionary of Economics, 2nd Edition (Palgrave Macmillan: New York).

This article explores the behavior of the stock market in Colombia with the information given by the Bolsa de Bogota Index (Indice de la Bolsa de Bogota, IBB). The index is analyzed from January, 1930 to December, 1998. The inflation rate covers the same period; the inflation rate as measured by...

This paper develops a general equilibrium model for a representative agent, production economy with stochastic internal habit formation. The model describes a scale-independent economy, with a unique stochastic investment opportunity set. Local correlation between the stochastic interest rate...

This paper quantitatively accounts for the cyclical dynamics of key macroeconomic housing and mortgage market variables using a tractable, search-theoretic model of housing with equilibrium mortgage default. To explain these dynamics, the model highlights the importance of liquidity spirals...

This paper investigates the macroeconomic effects of search risk in the housing market. To do so, I introduce a tractable directed search model of housing with mul- tidimensional buyer and seller heterogeneity. I incorporate this framework in an in- complete markets macroeconomic model with...

We demonstrate that in a CAPM economy Walras Law and the Tobin Separation Property characterize market demand in finite … sets of prices. Consequently, for any number n there exist CAPM economies which have at least n equilibria and hence have n …

We question a deep-ingrained doctrine in asset pricing: If an empirical characteristic-return relation is consistent with investor "rationality," the relation must be "explained" by a risk factor model. The investment approach changes the big picture of asset pricing. Factors formed on...
