Under the assumptions of the Consumption-based Capital Asset Pricing Model (CCAPM), Pareto optimal consumption allocations are characterized by each agent’s consumption process being adapted to the filtration generated by the aggregate consumption process of the economy. The wealth processes of the agents, however, are adapted to the finer filtration generated by aggregate consumption and the c...

This article analyzes a dynamic general equilibrium under a generalization of Merton’s (1987) investor recognition hypothesis. A class of informationally constrained investors is assumed to implement only a particular trading strategy. The model implies that, all else being equal, a risk premium on a less visible stock need not be higher than that on a more visible stock with a lower volatility...

Abstract This paper develops a simple new methodology to test financial market integration. Our technique is tightly based on a general intertemporal asset-pricing model, and relies on estimating and comparing expected discount rates across asset markets. Expected discount rates are allowed to vary freely over time, constrained only by the fact that they are equal across (riskadjusted) assets. ...

CAPM is often the method of choice among practioners for estimating the cost of equity for investment projects in developed economies. But for investment projects in emerging economies, CAPM tends to give estimates that are considered too low by experienced financial managers. Sometimes, CAPM estimates of the cost of equity for projects in emerging markets are even lower than those for comparab...

Under the assumption of normally distributed returns, we analyze whether the Cumulative Prospect Theory of Tversky and Kahneman (1992) is consistent with the Capital Asset Pricing Model. We find that in every financial market equilibrium the Security Market Line Theorem holds. However, under the functional form for the utility index suggested by Tversky and Kahneman (1992) financial market equi...

In this paper we propose a new approach to estimating the systematic risk (the beta of an asset) in a capital asset pricing model (CAPM). The proposed method is based on a wavelet multiscaling approach that decomposes a given time series on a scale-by-scale basis. At each scale, the wavelet variance of the market return and the wavelet covariance between the market return and a portfolio are ca...

This article provides an overview of evaluation studies for libraries, a brief introduction to the CAPM Project, a description of the theoretical background for the CAPM methodology and, finally, a discussion of the implementation of the methodology for the CAPM Project.

We show that labor search frictions are an important determinant of the cross-section of equity returns. In the data, sorting firms by loadings on labor market tightness, the key statistic of search models, generates a spread in future returns of 6% annually. We propose a partial equilibrium labor market model in which heterogeneous firms make optimal employment decisions under labor search fri...

We explore the asset pricing implications of an investment-based model that features a stochastic technology frontier and costly technology adoption. Firms adopt the latest technology embodied in new capital to reach a stochastic technology frontier, but this decision entails an adoption cost. The model predicts that old capital firms are more risky and hence offer a higher returns than young c...

Risk and return do not have the clearcut negative relationship that we assume in our textbook treatment. Industry level studies in different countries have shown that risk and return are positively related above industry median (rate of return) but negatively related below industry median (rate of return). These findings contradict any model along the line of capital asset pricing model. It als...
