We combine general equilibrium theory and théorie générale of stochastic processes to derive structural results about equilibrium state prices. -- General equilibrium ; Continuous-time finance ; Théorie générale of stochastic processes ; Asset pricing ; State prices

In this paper we study a continuous time, optimal stochastic investment problem under limited resources in a market with N firms. The investment processes are subject to a time-dependent stochastic constraint. Rather than using a dynamic programming approach, we exploit the concavity of the...

We study a continuous-time problem of optimal public good contribution under uncertainty for an economy with a finite number of agents. Each agent can allocate his wealth between private consumption and repeated but irreversible contributions to increase the stock of some public good. We study...

We introduce a notion of subgames for stochastic timing games and the related notion of subgame-perfect equilibrium in possibly mixed strategies. While a good notion of subgame-perfect equilibrium for continuous-time games is not available in general, we argue that our model is the appropriate...

We prove that in smooth Markovian continuous-time economies with potentially complete asset markets, Radner equilibria with endogenously complete markets exist. -- Potentially complete market ; Continuous-time financial ; market ; Radner equilibrium ; Itô diffusion ; Analytic transition density
