A dynamic pure-exchange general equilibrium model with uncertainty is studied. Fundamentals are supposed to depend continuously on states of nature. It is shown that: 1. if financial markets are complete, then asset prices vary continuously with states of nature, and; 2. if financial markets are...

We study how trading costs are reflected in equilibrium returns. To this end, we develop a tractable continuous-time risk-sharing model, where heterogeneous mean-variance investors trade subject to a quadratic transaction cost. The corresponding equilibrium is characterized as the unique...

The objective pursued in the present work is the identification of possible anomalies associated with daily seasonality in the returns of British companies listed on the London Stock Exchange. For this purpose, we examine the profitability of these companies for a the sample period between the...

Wealthier households obtain higher returns on their investments than poorer ones. How should the tax system account for this return inequality? I study capital taxation in an economy in which return rates endogenously correlate with wealth. The leading example is a financial market, where the...

Typically, models of stock prices or returns assume homogeneity of risk preference parameters. This study shows modeling of IPO prices necessarily is with reference to the distribution of risk preference parameters that already are represented in secondary equity markets. Modeling of stock...

We consider an economy where individuals face uninsurable risks to their human capital accumulation and study the problem of determining the optimal level of linear taxes on capital and labor income together with the optimal path of the debt level. We show both analytically and numerically that...
