The model is motivated by data showing that the Australian production of local manufactures is hurt by depreciations and invigorated by appreciations. The paper briefly presents such evidence and then proceeds to a theoretical analysis. The model aims at capturing short-to-medium run exchange...

|When international relations theorists use the concept of risk aversion, they usually cite the economics conception involving concave utility functions. However, concavity is meaningful only when the goal is measurable on an interval scale. International decisions are usually not of this type,...

Divide the decisionmaker's future into: (i) a pre-outcome period (lasting from the decision until the outcome of that decision is known), and (ii) a sequel post-outcome period (beginning when the outcome becomes known). Anticipated emotions in both periods may influence the decision, in...

Many important economic and political decisions are made by teams. In the economic literature, however, the decision units are frequently modeled as individual economic agents. The paper experimentally investigates the question to what extent observed team decisions under risk are actually...

If payoffs are tickets for binary lotteries, which involve only two money prizes, then rationality requires expected value maximization in tickets. This payoff scheme was increasingly used to induce risk neutrality in experiments. The experiment presented here involved lottery choice and...

Expected utility theory does not directly deal with the utility of chance. It has been suggested in the literature (Samuelson 1952, Markowitz 1959) that this can be remedied by an approach which explicitly models the emotional consequences which give rise to the utility of chance. We refer to...

This study test whether social reference points impact individual risk taking. In a laboratory experiment, decision makers observe the earnings of a peer subject before making a risky choice. We exogenously manipulate the peer earnings across two treatments. We find a signicant treatment effect...

We propose an experimental method to test individuals for prudence (i.e. downside risk aversion) outside the expected utility framework. Our method relies on a novel representation of compound lotteries which allows for a systematic parameterization that captures the full generality of prudence....

We examine the impact of ambiguity on economic behaviour. We present a relatively non-technical account of ambiguity and show how it may be applied in economics. Optimistic and pessimistic responses to ambiguity are formally modelled. We show that pessimism has the effect of increasing...
