This paper studies how the assignment of patents as collateral determines the savings of firms and magnifies the effect of innovative rents on investment in research and development (R&D). We analyse the behaviour of innovative firms that face random and lumpy investment opportunities in R&D....

We investigate conditions under which self-organized criticality (SOC) arises in a version of a dynamic entry game. In the simplest version of the game, there is a single location--a pool--and one agent is exogenously dropped into the pool every period. Payoffs to entrants are positive as long...

The rational expectations equilibrium of a small open economy can be subject to indeterminacy if foreign monetary policy does not satisfy the Taylor principle. We study the implications of foreign induced indeterminacy in the two-country version of the sticky-price small open economy model. Our...

The literature on R&D-based growth establishes that market equilibrium is inefficient and derives optimal R&D policy. Normative analyses of this type use the assumption of steady state, largely motivated by analytical convenience. This paper questions this steady-state approach by introducing...

This paper presents a model of learning about a game. Players initially have little knowledge about the game. Through playing the same game repeatedly, each player not only learns which action to choose but also constructs a personal view of the game. The model is studied using a hybrid payoff...

We provide an explicit characterization of the equilibrium when investors have heterogeneous risk preferences. Given market completeness, investors can achieve full risk sharing. Thus, a representative agent can be constructed, though this agent's risk aversion changes over time as the relative...

The new learning dynamic of Brown et al. [(1950). Solutions of games by differential equation. In: Kuhn, H.W., Tucker, A.W. (Eds.), Contributions to the Theory of Games I. Annals of Mathematics Studies, vol. 24. Princeton University Press, Princeton] is introduced to macroeconomic dynamics via...

We present a model of public provision of education for blacks in two discriminatory regimes, white plantation controlled, and white yeoman-town controlled. We show that the ability to migrate to a non-discriminating district constrains the ability of both types of regimes to discriminate. The...

The information content of prices is a central problem in the general equilibrium analysis of competitive markets. Rational expectations equilibrium identifies conditioning simultaneously on contemporaneous prices and private information as the mechanism by which information enters prices. Here...

We examine a search and matching model of the labor market with overlapping generations of workers. In this model, we focus on the effects of the finite lifetime of workers. As a result of finite lifetime very old workers with the same productivity as younger workers generally earn less. A...
