This paper considers a dynamic partnership model in which agents' future productivity depends in part on their current match. Efficient rankings over human capital distributions are characterized in several common stochastic orders. These rankings are used to characterize the returns to human...

This article studies an economy with borrowers (firms or individuals) under costly default. Borrowers defaulting under adverse economic conditions may, despite incurring default costs, emerge as wealthier than nonborrowers. Asset substitution is generally not pronounced, although a larger risk...

After taking into account positive transaction costs via tackling static nonlinear programming with dynamic programming, this paper reaches three main conclusions: 1) The aggregate excess demand function of each market will be discontinuous at many price points, but the transfiguration of the...

The incomplete information financial economic equilibrium (IIE) literature has been growing at an increasing rate since its inception in the early 1980s. This paper examines issues and concepts essential to understanding, implementing, and testing IIE and understanding its relation to complete...

This article studies an economy with borrowers (firms or individuals) under costly default. Borrowers defaulting under adverse economic conditions may, despite incurring default costs, emerge as wealthier than nonborrowers. Asset substitution is generally not pronounced, although a larger risk...

This article analyzes optimal, dynamic portfolio and wealth/consumption policies of utility maximizing investors who must also manage market-risk exposure using Value-at-Risk (VaR). We find that VaR risk managers often optimally choose a larger exposure to risky assets than non risk managers,...

In this paper we study the existence of bubbles for pricing equilibria in a pure exchange economy a la Lucas, with infinitely lived homogeneous agents. The model is analyzed under fairly general assumptions: no restrictions either on the stochastic process governing dividends' distribution or on...

This paper studies conditions under which the price of an asset is uniquely determined by its fundamental value (i.e., no bubbles can arise) in Lucas-type asset pricing models with unbounded utility. After discussing Gilles and LeRoy's (1992) example, we construct an example of a two-period,...

We analyze the joint effect of borrowing and short-sale constraints in a dynamic economy populated by two constrained investors with heterogeneous risk aversions and beliefs. We find that equilibrium prices adjust in such a way that the constraints never simultaneously bind. When the constraints...

In this paper, I study the existence and uniqueness of recursive equilibria in economies with aggregate and idiosyncratic risk. Rather than relying on compactness to establish existence, I exploit the monotonicity property of the equilibrium model and rely on arguments from convex analysis. This...
