This paper investigates whether insiders use private information in their decision to exercise executive stock options. Consistent with existing research, exercises overall do not yield subsequent abnormal returns. Categorising exercises by the proportion of stock sold at exercise yields a...

This paper uses an evolutionary approach incorporating the idea of natural selection to examine market behavior in a one-sided buyer auction market. Even with no traders' rationality (such as rational expectations and adaptive learning) and with each trader's behavior preprogrammed with its own...

This paper explores the phenomenon of lasting deviations of the exchange rate from its fundamental value in the foreign exchange market. Motivated by empirical observations a chartists-fundamentalists model is developed in which boundedly rational agents repeatedly choose between technical and...

Using monthly data from 1926:01 to 2003:12 for the United States, this paper examines the predictability of real stock prices based on the dividend-price ratio. In particular, we focus on estimating and forecasting a nonlinear exponential smooth autoregressive model (ESTAR). One motivation for...

In this paper, we investigate the out-of-sample forecasting ability of a genetic program to approach the dynamic evolution of the Yen/US$ and Pound Sterling/US$ exchange rates, and verify whether the method can beat the random walk model. Later on, we use the predicted values to generate a...

The 1987 stock market crash, the LTCM debacle, the Asian Crisis, the bursting of the high technology Dot-Com bubble of 2001-2 with 30% losses of equity values, events such as 9/11 and sudden corporate collapses of the magnitude of Enron - have radically changed the view that extreme events have...

When one constructs long-term investment plan, one needs to consider the fact that long-term bonds are still exposed to inflation risk. This paper studies the intertemporal portfolio-consumption decision where the investment opportunities include "inflation-indexed bonds" -- a modern financial...

We investigate for evidence of complex-deterministic dynamics in financial returns time series. By combining the Surrogate Data Analysis inferential framework with the MG-GARCH (Kyrtsou and Terraza, 2003) modelling approach, we examine whether the sequences are characterized by aperiodic and...
