Models of dynastic households have been traditionally used to analyze persistence in earnings and wealth across generations, more recently to study patterns of wealth and fertility, transfers to children and education choices. Using data of two generations from the PSID, this paper develops and...

We consider the role of product market competition in disciplining managers in a moral hazard setting. Competition has two effects on a firm. First, the expected revenue or the marginal benefit of effort declines, leading to weakly lower effort. Second, the cost of inducing high effort increases...

Predatory pricing - a deliberate strategy of pricing aggressively in order to eliminate competitors - is one of the more contentious areas of antitrust policy and its existence and efficacy are widely debated. The purpose of this paper is to formally characterizes predatory pricing in a modern...

Predatory pricing . a deliberate strategy of pricing aggressively in order to eliminate competitors . is one of the more contentious areas of antitrust policy. This paper uses a modern industry dynamics framework to characterize predatory pricing by isolating a Firm’s equilibrium predatory...

We bring together the theories of duality and dynamic programming. We show that the dual of an additively separable dynamic optimization problem can be recursively decomposed using summaries of past Lagrange multipliers as state variables. Analogous to the Bellman decomposition of the primal...

This paper models flows of foreign direct investment (FDI) in a two country, two sector DSGE framework. The allocation of capital to production capacity abroad is subject to a search-and-matching friction with endogenous capital reallocation. The model is calibrated on observed inflows and...

Building a model with three imperfect markets - goods, labor and credit - representing a product’s life-cycle, we find that goods market frictions drastically change the qualitative and quantitative dynamics of labor market variables. The calibrated model leads to a significant reduction in...
