It is known that the Capital Asset Pricing Model (CAPM) provides an expression which relates the expected return of an asset to its systematic risk. In a decision making problem involving financial data however, we have to take in account the uncertainty given by the imprecision and the incompleteness of the information. Uncertainty in the data may be treated by considering, rather than a singl...

We present a tractable, static, general equilibrium model with multiple sectors in which firms offer workers incentive contracts and simultaneously raise capital in stock markets. Workers optimally invest in the stock market and at the same time hedge labor income risk. Firms rationally take agents’ portfolio decisions into account. In equilibrium, the cost of capital of each sector is endogeno...

Many studies have documented portfolio strategies that provide returns in excess of those expected, given the level of risk of the portfolio. Variables that seem to have predictive power for equity returns include the market capitalization of the firm’s equity and the ratio of the firm’s book equity to market equity (BE/ME). Firms with low market capitalization and high book-tomarket values see...

Since the birth of the Capital Asset Pricing Model (CAPM), enormous efforts have been devoted to studies evaluating the validity of this model, a unique breakthrough and valuable contribution to the world of financial economics. Some empirical studies conducted, have appeared to be in harmony with the principles of CAPM while others contradict the model. The aim of this paper is to study if the...

We develop structural econometric tests of asset pricing theory for application to data from experimental financial markets. The tests differ from those used in the analysis of field data because they verify the consistency between prices and allocations, as opposed to merely testing whether only prices satisfy equilibrium restrictions. Our tests also differ from standard field tests because th...

We derive an international asset pricing model that assumes investors have preferences of the type “keeping up with the Joneses.” In an international setting investors compare their current wealth with that of their peers who live in the same country. Investors value domestic assets because they are more highly correlated with the domestic benchmark. In equilibrium, this gives rise to a multifa...

Asset prices are typically modeled with the geometric Brownian motion (GBM). Correlation between the assets is exogenously modeled and then ad-hoc assigned to the asset prices. This is conceptually and mathematically unsatisfying. We create a new, simple approach, which simultaneously models stochastic volatility and stochastic correlation. This approach replicates the realworld volatility – co...

We extend and unify existing international asset pricing models for perfect capital markets by allowing both exchange rates and inflation rates to be stochastic and investors to consume both tradable and nontradable goods. We show that country-specific demand for risky assets arises from two sources: PPP-deviationrate differential risks and nontradable-good-specific inflation-rate-differential ...

Shariah compliant firms operating in an environment with little to no access a robust Islamic capital market (such as the United States (US) stock market) will exhibit consistent bias towards certain corporate financial behaviour. Does this subsequently lead skewed asset pricing behaviour? To answer question, paper investigates behaviour of multiple samples listed US compared overall convention...

the current paper examines intertemporal capital asset pricing model in iran’s stock market. dynamic conditional correlation was used to estimate conditional variance and covariance portfolios with market returns. time varying beta is estimated by kalman filter method. based on the obtained results, risk aversion coefficients were between 0.013 and 0.28 and the average was 0.20. significance of...
