In this paper, we investigate the importance of different loss functions when estimating and evaluating option pricing models. Our analysis shows that it is important to take into account parameter uncertainty, since this leads to uncertainty in the predicted option price. We illustrate the...

Returns in financial assets show consistent excess kurtosis, indicating the presence of large fluctuations not predicted by Gaussian models. Mandelbrot (1963) first proposed the idea that price changes distributed according to a Lévy stable law. The unique feature of Lévy-stable distributions...

GARCH-type models have been very successful in describing the volatility dynamics of financial return series for short periods of time. However, for example macroeconomic events may cause the structure of volatility to change and the assumption of stationarity is no longer plausible. In order to...

Previous research indicates that the US market for inflation-linked bonds is not efficient and that market inefficiencies can be exploited by informed traders who include survey estimations or inflation model forecasts in trades on break-even inflation. Results from this extended research over a...

It is a well known empirical fact that actual option prices show persistent and systematic deviations from Black-Scholes option values. While a substantial number of enhancements have been proposed in the literature, these approaches typically leave investors’ preferences towards risk...

This paper develops and tests a heterogeneous agents model for the option market. Our agents have different beliefs about the future level of volatility of the underlying stock index and trade accordingly. We consider two types of agents: fundamentalists and chartists, who are able to switch...

Previous research suggests that the market for index-linked bonds is not entirely efficient and that these inefficiencies can be exploited by including inflation forecasts in trades on break-even inflation. Inspired by those results, we test the informational content of inflation expectations...
