We uncover a positive stock market risk-return tradeoff after controlling for the covariance of market returns with the value premium. Fama and French (1996) conjecture that the value premium proxies for investment opportunities; therefore, by ignoring it, early specifications suffer from an...

This article investigates the impact of currency convertibility under the current account on the informational linkage between official and swap market exchange rates for Chinese currency (renminbi). Findings indicate that currency convertibility increased the informational connection between...

This paper examines risk minimization hedging effectiveness for major storable and nonstorable agricultural commodity futures markets. Based on the error correction model bivariate GARCH frameworks, some evidence is found that the hedging effectiveness is stronger for storable commodities than...

This paper proposes a class of test procedures for a structural change with an unknown change point. In particular, we consider a general financial time series model with conditional heteroskedasticity. The test statistics are constructed via the empirical distribution approach and aim at...

This paper examines high frequency stock returns with buy/sell signals. It demonstrates how such trading information could be utilized in a qualitative threshold framework to explain and predict the asymmetric behaviour of intrady stock returns. The study discovers that the buyer-dominating...

This paper examines daily return predictability for eighteen international stock index ETFs. The out-of-sample tests are conducted, based on linear and various popular nonlinear models and both statistical and economic criteria for model comparison. The main results show evidence of...

In this paper we examine dynamic relationships among wheat prices from five countries for the years 1981-1999. Error correction models and directed acyclic graphs are employed with observational data to sort-out the dynamic causal relationships among prices from major wheat producing regions:...

We investigate the international transmission of inflation among G-7 countries using a data-determined vector autoregression analysis, as advocated by Swanson and Granger (1997). Over the period 1973 to 2003, we find that U.S. innovations have a large effect on inflation in the other countries,...

This article shows that against the neglect on Internet asset value in traditional financial accounting theory and practice, the authors proposed an improved real option model for assessing Internet asset value based on Metcalfe's law and adaptive expectation hypothesis, and used it to assess...
