We develop a tractable general theory for the study of the economic and demographic impact of epidemics, notably its distributional consequences. To this end, we build up a three-period overlapping generations model where altruistic parents choose optimal health expenditures for their children...

This paper develops a continuous time asset pricing model of debt and equity in a framework where equityholders decide when to default but creditors decide when to liquidate. This framework is relevant for environments where creditors exert a significant influence on the timing of liquidation,...

This paper proposes an approximation to the consumption function. The approximation is based on the analytic properties of the consumption function in the buffer-stock model. In such model, the consumption function is increasing and concave and its derivative is bounded from above and below. We...

This paper introduces a new algorithm, the recursive upwind Gauss-Seidel method, and applies it to solve a standard stochastic growth model in which the technology shocks exhibit heteroskedasticity. This method exploits the fact that the equations defining equilibrium can be viewed as a set of...

This paper develops a general approach for the single period portfolio optimization problem in a multidimensional general and partial moment space. A shortage function is defined that looks for possible increases in odd moments and decreases in even moments. A main result is that this shortage...

This paper aims to open a new avenue for research in continuous-time financial market models with endogenous prices and heterogenous investors. To this end we introduce a discrete-time evolutionary stock market model that accommodates time periods of arbitrary length. The dynamics is...

The solution structure of the set of optimal solutions of the shallow lake problem, a problem of optimal pollution management, is studied as we vary the values of the system parameters: the natural resilience, the relative importance of the resource for social welfare and the future discount...

In this paper we present a dynamic model of a firm which is deciding whether to outsource parts of its production to a less developed economy where wages and the level of technology are lower. Outsourcing reduces production costs but is associated with spillovers to foreign potential...

This paper investigates the interactions between the investment and financing decisions of a firm under manager-shareholder conflicts arising from asymmetric information. In particular, we extend the manager-shareholder conflict problem in a real options model by incorporating debt financing. We...

This paper analyzes an alternating offer model of bargaining over the sale of an asset in a market, such as that for housing, in which another agent may come and compete for the right to strike a deal. The analysis allows the buyer and seller to have possibly differing views as to how likely...
