This paper studies models where the correspondences (or functions) under consideration are never increasing (or weakly decreasing) in endogenous variables, and weakly increasing in exogenous parameters. Such models include games of strategic substitutes, and include cases where additionally,...

This paper uses novel data on the performance of pools underlying asset- backed securities to estimate a competing risks model of default and prepayment on subprime automobile loans. We find that prepayment rates increase rapidly with loan age but are not affected by prevailing market interest...

Limited liability debt financing of irreversible investments can affect investment timing through an entrepreneur's option value, even after compensating a lender for expected default losses. This non-neutrality of debt arises from an entrepreneur's unique investment opportunity, and it is shown...

One explanation provided for the relatively high and increasingly stable spreads for moderate-sized IPOs ($20-$80 million) documented in Chen and Ritter (2000) is that issuing firms focus less on price and more on a combination of investment bank-differentiating factors (such as underwriter...

In competitive economies with private firm ownership, incomplete markets, and firm shareholders changing over time, several firm objectives have been proposed. Some are useful to understand efficiency of equilibria, and others are explicitly consistent with majority shareholder control or...

A new measure of constrained efficiency for application in economies with incomplete markets is presented. This measure --- termed Allais- Malinvaud efficiency --- can be viewed as adjusting for market incompleteness not fully captured in previous work. It is shown that equilibrium allocations...

In recent years, one area of growing concern in corporate governance is the accounting and transfer of risk using special purpose entities (or trusts). Such entities are used widely in issuing asset-backed securities. This paper provides an overview of the asset-backed securities market, and...

We wish to study optimal dynamic nonlinear income taxes. Do real world taxes share some of their features? What policy prescriptions can be made? We study a two period model, where the consumers and government each have separate budget constraints in the two periods, so income cannot be...

This paper presents a micro-model of knowledge creation and transfer in a small group of people. Our model incorporates two key aspects of the cooperative process of knowledge creation: (i) heterogeneity of people in their state of knowledge is essential for successful cooperation in the joint...

We study the indeterminacy of equilibrium in the Fujita-Krugman (1995) model of city formation under monopolistic competition and increasing returns. Both the number and the locations of cities are endogenously determined. Assuming smooth transportation costs, we examine equilibria in...
