This paper extends the methodology developed in Chien, Cole and Lustig (2011 & 2012) (hereafter CCL2011 and CCL2012, respectively) to analyze and compute the equilibria of economies with heterogeneous agents who have different asset trading technologies and are subject to both aggregate and...

In this paper we investigate the macro-economic equilibria of an economy in which credit contracts have both adverse selection and incentive effects. The terms of credit contracts include both an interest rate and a collateral requirement. We show that in this richer model all types of borrowers...

The consequences of information differences across investors in capital markets are still much debated. This paper examines the relation between information differences across investors and the cost of capital, and makes three points. First, in models of perfect competition, information...

Many identify inflated credit ratings as one contributor to the recent financial market turmoil. We develop an equilibrium model of the market for ratings and use it to examine possible origins of and cures for ratings inflation. In the model, asset issuers can shop for ratings -- observe...

In a frictionless world, investment is perfectly elastic to changes in the discount rate. With financial frictions, investment is less elastic, meaning that a given magnitude of change in investment is associated with a higher magnitude of change in the discount rate. Equivalently, investment is...

This paper studies how capital market imperfections affect the welfare effects of forming a currency union. The analysis considers a bank-only world where intermediaries compete in Cournot fashion and monitoring and state verification are costly. The first part determines the credit market...

This methodological paper presents a class of stochastic processes with appealing properties for theoretical or empirical work in finance and macroeconomics, the quot;linearity-generatingquot; class. Its key property is that it yields simple exact closed-form expressions for stocks and bonds,...

This paper describes the role that informational imperfections in capital markets are likely to play in business cycles. It then developes a simple illustrative model of the impact of adverse selection in the equity market and the way in which this may lead to large fluctuations in the effective...

Noise traders are agents whose theoretical existence has been hypothesized as a way of solving certain fundamental problems in Financial Economics. We briefly review the literature on noise traders. The is an entry for The New Palgrave: A Dictionary of Economics, 2nd Edition (Palgrave Macmillan:...

The welfare benefits of financial markets depend in large part on how effectively households use these markets. The study of household finance is challenging because household behavior is difficult to measure accurately, and because households face constraints that are not captured by textbook...
