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...

This paper contributes to the debate about the extent to which liquidity risk affects asset prices. Motivated by evidence on downward liquidity spirals, flights to liquidity and investor perceptions of risk, we develop and test a liquidity-adjusted capital asset pricing model in which the key innovation is separating liquidity risk into asymmetric upside and downside risks. Our model bridges th...

This study investigates the applicability of the CAPM in explaining the cross section of stock return on the Karachi Stock Exchange for the period September 1992 to April 2006. Unlike earlier studies on emerging markets this study is carried out with a broader scope. Firstly, the tests are conducted on individual stocks as well as size sorted portfolios and industry portfolios. Secondly, the te...

Article history: Received 6 September 2011 Accepted 13 February 2012 Available online 8 March 2012 A number of recent papers have developed multifactor extensions of the classic consumption capital asset pricing model (CCAPM) and generally concluded that conditioning information improves the empirical performance. This paper asks whether the superior empirical performance of the multifactor CCA...

Forward exchange rate unbiasedness is rejected in tests from the current floating exchange rate era. This paper surveys advances in this area since the publication of Hodrick's (1987) survey. It documents that the change in the future exchange rate is generally negatively related to the forward discount. Properties of the expected forward forecast error are reviewed. Issues such as the relation...

In this paper we test for the inclusion of the bid-ask spread in the consumption CAPM, in the UK stock market over the time period of 1980-2000. Two econometric models are used; first, Fisher’s (1994) asset pricing model is estimated by GMM, and secondly, the VAR approach proposed by Campbell and Shiller is extended to include the bid-ask spread. Overall the statistical tests are unable to reje...

The existence of mean-variance efficient positive portfolios – portfolios with no negative weights – is a key requirement for equilibrium in the Capital Asset Pricing Model (CAPM). Brennan and Lo (2010) define an “impossible frontier” as a frontier on which all portfolios have at least one negative weight. They prove that for randomly drawn covariance matrices the probability of obtaining an im...

Survey evidence suggests that many investors form beliefs about future stock market returns by extrapolating past returns. Such beliefs are hard to reconcile with existing models of the aggregate stock market. We study a consumption-based asset pricing model in which some investors form beliefs about future price changes in the stock market by extrapolating past price changes, while other inves...

The need for understanding the propagation mechanisms behind the recent financial crises lead the increased interest for works associated with systemic risks. In this framework, network-based methods have been used to infer from data the linkages between institutions (or companies. Part of the literature postulates that systemic risk is strictly related (if not equal) to systematic risk. In thi...
