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...

We estimate a generic agent-based model in which agents have heterogeneous beliefs about the future price to see to what extent behaviour differs across assets, and what this implies for market stability. We find evidence for behavioural heterogeneity for all asset classes, except for equities....

This paper empirically assesses heterogeneous expectations in asset pricing. We use a maximum likelihood approach on S&P500 data to estimate a structural model. Our empirical results are consistent with a market populated with fundamentalists and chartists. In addition, agents switch between...

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...

Gravity equations are a widely used tool in the International Business (IB) literature to explain country-level trade and FDI flows. Against the background of its increased popularity and data availability, a range of commonly made econometric mistakes have recently been discussed in the...

This paper combines survey forecasts with a heterogeneous agent model to examine the dispersion of expectations of participants in the foreign exchange market. We find distinct variations in the level of dispersion and document that dispersion arises because of the combined effect of market...
