Studies of household stock market participation report low participation rates. The explanations cited are that the fixed costs associated with participation and high risk aversion discourage households from buying stocks. However, the low participation rate findings are unchallenged. We argue...

This paper investigates the sources of time-varying risk for the US stock and bond markets. The model captures the change in the risk premium due to each market's own volatility risk and the covariance risk. We test for the effects of macroeconomic news on time-varying volatility as well as...

The study investigates whether the stable Paretian hypothesis is more adequate to explain the returns of US agency mortgage pass-through securities than the traditional normal distribution assumption. The daily returns of six representative index generics of Lehman Brothers are investigated in...

The emergence of Credit Default Swap (CDS) indices and corresponding credit risk transfer markets with high liquidity and narrow bid-ask spreads has created standard benchmarks for market credit risk and correlation against which portfolio credit risk models can be calibrated. Integrated risk...

In this article, we introduce two new six-parameter processes based on time-changing tempered stable distributions and develop an option pricing model based on these processes. This model provides a good fit to observed option prices. To demonstrate the advantages of the new processes, we...

We investigate whether the US equity market exhibits underreaction or overreaction. More specifically, we study the directional and magnitude effects associated with abnormal market reaction. The directional effect is the phenomenon that an extreme price movement will be followed by a price...

There is considerable empirical evidence that financial returns exhibit leptokurtosis and nonzero skewness. As a result, alternative distributions for modelling a time series of the financial returns have been proposed. A family of distributions that has shown considerable promise for modelling...
