In this article, we show how to analyse analytically the equilibrium policies and prices in an economy with a stochastic investment opportunity set and incomplete financial markets, when agents have power utility over both intermediate consumption and terminal wealth, and face portfolio...

We develop a method that allows one to compute incomplete-market equilibria routinely for Markovian equilibria (when they exist). The main difficulty to be overcome arises from the set of state variables. There are, of course, exogenous state variables driving the economy but, in an incomplete...

This paper studies the conditions for aggregation, portfolio separation and effective completeness of competitive allocations in general equilibrium models with incomplete markets where agents have general preference and endowment distributions. We show that these properties are distinct....

The purpose of this paper is to analyze endogenous asset innovation by an entrepreneurial exchange owner in a general equilibrium model of incomplete security markets with financial transaction fees. A monopolistic market maker has the technology to introduce a new option into the economy and...

The estimation of the discount rate for an investment project in conditions of risk relies upon two crucial assumptions: market completeness and well-diversified investors. Although, these two assumptions are tenable in developed capital markets, they are not suitable in emerging markets. In...

In this paper, we examine an exchange economy with a financial market composed of three assets: a share of a stock, an European call option written on the stock, and a riskless bond. The financial market is assumed to be incomplete and the option is not a redundant asset. In such a case the...

This paper tackles the "aggregation problem" for stochastic economies with possibly incomplete market. An "aggregation theorem" is proved towards an analytic construction of the representative agent’s utility function. This is done within a general time-state setup with general utility...

These lecture notes are about financial innovations. We ask why are there some innovation and how is an innovative idea realized. This forces us to consider practical and structural aspects (regulations, taxation, markets) as key drivers of innovations and also basic formal aspects in valuation....

This paper argues that the introduction of a short-sale constraint in the Arrow-Radner frameworkinvalidates standard definitions of complete and incomplete markets. In this constrained set-up,two threshold values with familiar properties arise.The case of a zero short-sale bound set on some...

In this paper we argue that in realistically calibrated two period general equilibrium models with incomplete markets CAPM-pricing provides a good benchmark for equilibrium prices even when agents are not mean-variance optimizers and returns are not normally distributed. We numerically...
