This paper investigates a sample of 27 OECD countries to test whether national elections induce higher stock market volatility. It is found that the country-specific component of index return variance can easily double during the week around an Election Day, which shows that investors are...

Evidence suggests that arbitragers exchange investment ideas. We analyze why and under what circumstances sharing occurs. Our model suggests that sharing ideas will lead to the following: more efficient asset prices, larger arbitrager profits, and correlated arbitrager returns. We predict that...

Past research has shown that the level of operating accruals is a negative cross-sectional predictor of stock returns. This paper examines whether the accrual anomaly extends to the aggregate stock market. In contrast with cross-sectional findings, there is no indication that aggregate operating...

A new alternative diffusion model for asset price movements is presented. In contrast to the popular approach of Brownian motion it proposes deterministic diffusion for the modelling of stock price movements. These diffusion processes are a new area of physical research and can be created by the...

We analyze commonality in informed trading across stocks, and how informed trading varies with the structural and trading characteristics of a firm. We thereby isolate the residual level of informed trading that is unrelated to commonality, trading characteristics, and structural...

This paper provides an indepth analysis of Irredeemable Convertible Unsecured Loan Stocks or ICULS. A Malaysian variant of the convertible bond, ICULS are a hybrid security. Despite their introduction and trading since the late 1980’s, not much work have been done on them. This paper presents...

This paper develops two competing hypotheses for the relation between the cross-sectional standard deviation of logarithmic firm fundamental-to-price ratios (``dispersion'') and expected aggregate returns. In models with fully rational beliefs, greater dispersion indicates greater risk and...

I provide a theoretical model for two empirical phenomena observed in the NYSE and Nasdaq markets. First is the bid-ask bounce recently studied by Heston, Korajczuk and Sadka (HKS, 2008) for high-frequency data. Second is a temporary liquidity squeeze observed by Madureira and Underwood (2008)...

Inter-dealer trading in US Treasury securities is almost equally divided between two electronic trading platforms that have only slight differences in terms of their relative liquidity and transparency. BrokerTec is more active in the trading of 2-, 5-, and 10-year T-notes while eSpeed has more...
