This paper shows that the R² and the standard error have fatal flaws and are inadequate as accuracy tests for models with heterogeneous agents and aggregate risk. Using data from a Krusell-Smith economy, I show that approximations for the law of motion of aggregate capital for which the true...

Several regulatory authorities worldwide have recently imposed forward contract obligations on electricity producers as a way to mitigate their market power. In this paper we investigate how such contractual obligations affect equilibrium bidding in electricity markets, or in any other...

A competitive stock market is embedded into a neoclassical growth economy to analyze the interplay between the acquisition of information about firms, its partial revelation through stock prices, capital allocation and income. The stock market allows investors to share their costly private...

We develop a model of endogenous lobby formation in which wealth inequality and political accountability undermine entry and financial development. Incumbents seek a low level of effective investor protection to prevent potential entrants from raising capital. They succeed because they can...

We use portfolio theory to quantify the efficiency of state-level sectoral patterns of production in the United States. On the basis of observed growth in sectoral value-added output, we calculate for each state the efficient frontier for investments in the real economy. We study how rapidly...

This paper investigates whether privatization in emerging economies has a significant indirect effect on local stock market development through the resolution of political risk. We argue that a sustained privatization program represents a major political test which gradually resolves uncertainty...

We examine stock returns in a cross section of emerging and mature markets (47countries) between 1980-99. The level of financial development turns out to be an important determinant of the performance of stock returns. In general, a deeper and higher quality banking system decreases the...

This paper develops a theory of international trade in which financial development and factor endowment jointly determine comparative advantage. We apply the financial contract model of Holmstrom and Tirole to the Heckscher-Ohlin-Samuelson (HOS) framework. A key result is what we call the law of...
