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...

An important puzzle in corporate taxation is that effective tax rates have fallen significantly while tax revenue has simultaneously risen in most countries. Moreover, the gross profitability of firms seems to be lower in high-tax countries, even though standard models of international investment would yield the opposite conclusion. We offer an explanation for these stylized facts by setting up...

Available online 10 June 2014 This paper analyzes the volatility linkage across the U.S., European, German, Japanese, and Swiss equity markets from 1999 to 2009. Both the unconditional and conditional correlations exhibit large fluctuations during the sample period. The results from the VAR analysis show an asymmetric two-way relation between the VIX and other market volatility indices, in whic...

Previous studies typically find a statistically insignificant relationship between the market risk premium and its expected volatility. Further, several of these studies estimate a negative risk return tradeoff contrary to the predictions of mainstream theory. Using simulations, I demonstrate that even 100 years of data constitute a small sample that may easily lead to this finding even though ...

We incorporate long-term defaultable corporate bonds and credit risk in a dynamic stochastic general equilibrium business cycle model. Credit risk amplifies aggregate technology shocks. The debt-capital ratio is a new state variable and its endogenous movements provide a propagation mechanism. The model can match the persistence and volatility of output growth as well as the mean equity premium...

I model inefficient resource allocations in M-form organizations due to influence activities by division managers that skew capital budgets in their favor. Corporate headquarters receives two types of signals about investment opportunities: private signals that can be distorted by managers, and public signals that are undistorted but noisy. Headquarters faces a tradeoff between the cost of atta...

This paper investigates the consequences of imperfect and uneven factor market development for farm efficiency in rural China. In particular, we estimate the extent to which an inverse relationship in farm productivity can be attributed to the administrative (instead of market) allocation of land, and the extent of unevenly developed non-agricultural opportunities. Using a recently collected ho...

The stock's contribution to the asymmetry and the fat tails of the market portfolio's payoff are priced into a coskewness premium and a cokurtosis premium. We construct zero-investment strategies ...

We explore sell-side debt analysts’ contributions to the efficiency of securities markets. We document that debt returns lag equity returns less when debt research coverage exists, consistent with debt analysts facilitating the process by which available information is impounded in debt prices. The effect is incremental to, but comparable in magnitude to, hedge fund ownership’s effect. No such ...
