This paper analyzes the determinants of regulatory capital (the minimum required by regulation) and economic capital (the capital that shareholders would choose in absence of regulation) in the context of the single risk factor model that underlies the New Basel Capital Accord (Basel II). The...

It is well known from time series analysis that shocks to aggregate output have very persistent effects. This paper argues that the relation between the expected growth rate of a firm and its size\ provides a microfoundation for such aggregate persistence. The empirical evidence indicates that...

We explore the business-cycle implications of agency problems between firms and financiers. We show how these problems create liquidity shortages that can lead to corporate bankruptcy, and may generate aggregate, endogenous cycles in an economy that otherwise would have had a unique, stationary...

We study the properties of mimicking portfolios in an intertemporal APT model, in which the conditional mean and covariance matrix of returns vary in an interdependent manner. We use a signal extraction approach, and relate the efficiency of (possibly) dynamic basis portfolios to mean square...

Poland's current challenge is to somplete its transition to a fully developed market economy, while advancing towards integration into the European Union. This paper is devoted to analyzing the Polish labor market's main institutions, circa 1995, in the areas of labor reallocation, wage setting,...

In an economy with one riskless and one risky asset, we compare the Sharpe ratios of investment funds that allow: i) timing strategies which forecast the market using simple regressions; ii) a strategy which uses multiple regression instead; and iii) a passive allocation which combines the funds in...
