We consider an experimental setting where traders in stock markets or exchange rate markets receive one stylized piece of information at a time about the value of an asset. We find that having limited knowledge about the prior distribution of true asset values does not hamper the decision making...

The conjunction fallacy occurs whenever probability compounds are thought of as more likely than its component probabilities alone. In the experiment we present, subjects chose between simple and compound lotteries after some practice. Depending on the condition, they were given more or less...

The strategy method is becoming an important tool in experimental methodology. This study examines how well this method works in an individual decision experiment. Subjects are faced with a sequential search problem. After extensive practice solving the problem and formulating strategies, they...

Economics has devoted little attention so far as to whether the type of decision maker matters for economic decisions. However, many important decisions like those on monetary policy or a company's business strategy are made by (small) groups rather than an individual. We compare behaviour of...

We analyze lottery-choice data in a way that separately estimates the effects of risk aversion and complexity aversion, and allows both both of these to vary between individuals, and also to change with experience. The data is from an experiment in which 80 subjects engage in a sequence of 54...

This paper presents a neural network model developed to simulate the endogenous emergence of bounded-rational behavior in normal-form games. There exists an algorithm which, if learnt by a neural network, would enable it to perfectly select Nash equilibria in never before seen games. However,...

Experimenter demand effects refer to changes in behavior by experimental subjects due to cues about what constitutes appropriate behavior. We argue that they can either be social or purely cognitive, and that, when they may exist, it crucially matters how they relate to the true experimental...

Personality questionnaires have been used and can be used to predict behavior in economic settings. Using two sets of state-of-the-art measures from personality psychology (the Big Six) and social psychology (Social Value Orientation), we find that the behavior of men is predictable in the first...

Many decisions in economics and finance have to be made under severe time pressure. Furthermore, payoffs frequently depend on the speed of decision-making, like, for instance, when buying and selling stocks. In this paper, we examine the influence of time pressure and time-dependent incentive...
