This experimental study investigates whether individuals prefer bounded rationality over rational choice theory when facing simple investment tasks. First, participants state some personal parameters that serve as an input to render a theoretical approach, namely satisficing or optimality,...

Overall, 72 subjects invest their endowment in four risky assets. Each com-bination of assets yields the same expected return and variance of returns. Illusion of expertise prevails when one prefers nevertheless the self-selected portfolio. After being randomly assigned to groups of four...

In this paper, we apply the bounded rationality approach to an investment situation. In a simple setting where an investor decides between a riskless bond and a risky asset, we distinguish three aspiration levels: a lowest threshold which one wants to guarantee, the aspiration level given by...

The paper explores the applicability of bounded rationality theory. In particular, we investigate whether basic principles of aspiration formation and satisficing behavior are transferable between similar situations. Individuals are sequentially confronted with two risky investment tasks, a...

In a large scale newspaper experiment 5,132 readers of the German weekly, Die Zeit, participated in a three-person bargaining game. In our data analysis we focus on (1) the influence of age, gender, profession and the medium chosen for participation on bargaining behavior and on (2) the external...

Leadership is important for the well-functioning of organizations. We examine the effects of leadership on contributions in public goods experiments. Leadership by example is implemented by letting one group member contribute to the public good before followers do. Such leadership increases...

We examine the effects of leading by example in voluntary contribution experiments. Leadership is implemented by letting one group member contribute to the public good before followers do. Such leadership increases contributions in comparison to the standard voluntary contribution mechanism,...
