This paper studies an (S,s) pricing model in the presence of inflation and price competition in search markets. I present a model in which consumers' search technologies can influence firms' price setting, price dispersion, and the market structure. The result obtained shows that although price...

Analytic methods for solving asset pricing models are developed to solve asset pricing models. Campbell and Cochrane's [1999. By force of habit, a consumption-based explanation of aggregate stock market behavior. Journal of Political Economy 107, 205-251] habit persistence model provides a...

This paper develops a simple life-cycle model that embeds a theory of debt restrictions based on the existence of inalienable property rights a la Kehoe and Levine [1993. Debt constrained asset markets. Review of Economic Studies 60(4), 865-888; 2001. Liquidity constrained markets versus debt...

This paper analyses a real options model of mergers and takeovers between two firms experiencing different, but correlated, uncertainty. It is assumed that mergers do not just lead to efficiency gains, but are also an act of diversification. Due to the latter assumption the region where a merger...

This paper analyses the dynamic implications of an asset-pricing model with incomplete participation due to entry costs. It is shown that heterogeneity in entry costs can lead to the existence of multiple stochastic sunspot equilibria, whereby the number of agents in the market and asset prices...

In this article we propose a method for solving a general class of four-dimension nonlinear modified Hamiltonian dynamic systems in closed form. This method may be used to study several intertemporal optimization problems sharing a common structure, which involves unbounded technological...

This paper examines the equilibrium when stock market crashes can occur and investors have heterogeneous attitudes towards crash risk. The less crash averse insure the more crash averse through options markets that dynamically complete the economy. The resulting equilibrium is compared with...

The wealth dynamics of insurance companies strongly depends on the success of their investment strategies, but also on liquidity shocks which occur during unfavorable years, when indemnities to be paid to the clients exceed collected premia. An investment strategy that does not take liquidity...
