This paper examines whether trading based on market sentiment can explain mispricing in S&P 500 options. We test the heterogeneous agent s option pricing model developed in Frijns et al. (2010), where our agents have different beliefs about the future level of market volatility and trade...

We explicitly examine the role of culture in corporate takeover decisions. Prior research suggests that the risk aversion of CEOs affects their takeover decisions. In this paper, we argue that managerial risk aversion at a national level is a cultural trait and affects the net synergies. CEOs of...

It is a well known fact that at high sampling frequencies, the contamination of microstructure noise causes the Realized Variance to be a biased measure of the Integrated Variance. Recent developments in this field propose sampling on lower frequencies, sub-sampling techniques, or bias...

The current paper proposes a conditional volatility model with time varying coefficients based on a multinomial switching mechanism. By giving more weight to either the persistence or shock term in a GARCH model, conditional on their relative ability to forecast a benchmark volatility measure,...

This paper develops and tests a heterogeneous agents model for the option market. Contrary to the common practice in the heterogeneous agents literature of modeling the level process, we introduce heterogeneity and switching in the variance process of the stock market. The market consists of two...

The behavioural approach to decision making under uncertainty combines insights from psychology and sociology into economic decision making. It steps away from the normative homo economicus and introduces a positive approach to human decision making under uncertainty. We provide an overview of...

We find that investor sentiment should affect a firm's employment policy in a world with moral hazard and noise traders. Consistent with the model's predictions, we show that higher sentiment among US investors leads to: (1) higher employment growth worldwide; (2) lower labor productivity, as the...

Disagreement is used as a measure of both investor heterogeneity and uncertainty. We study whether disagreement captures heterogeneity or uncertainty for the foreign exchange market. We do so by relating disagreement to alternative measures of uncertainty, as well as by taking advantage of the...
