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 reviews the empirical literature on heterogeneous beliefs and asset price dynamics that challenges the traditional rational agent framework. Emphasis is given to the validation and estimation of (dynamic) heterogeneous agent models that have their roots in the agent-based literature....

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...

In statistics, samples are drawn from a population in a datagenerating process (DGP). Standard errors measure the uncertainty in sample estimates of population parameters. In science, evidence is generated to test hypotheses in an evidencegenerating process (EGP). We claim that EGP variation...

Based on high-frequency data for Norway and Sweden, we investigate to what extent explicit forward guidance from monetary policy makers, by means of publishing the path of expected future policy rates, affects the market yield curve. We summarise movements in the yield curve by two latent...

In this paper we study financial spillovers from the European Central Bank's (ECB) monetary policy and communication, and whether they have consequences for the effectiveness of domestic monetary policy of small open economies. Recent work suggests that the "trilemma" in international economics...

We employ a structural VAR model to investigate direct and indirect effects of oil price changes on the Norwegian effective exchange rate (I44). The model is estimated on different subsamples and with different model specifications. Our main finding is that the direct effect of oil price shocks...

Anecdotal evidence as well as previous empirical analysis indicates that the relation between oil price changes and movements in the Norwegian krone is not stable over time. We can observe that there is no or only a weakly significant correlation between oil price changes and Norwegian krone...
