In an experiment with 739 subjects we study whether and how different interventions might have an influence on the degree of moral behavior when subjects make decisions that can generate negative externalities on uninvolved parties. Particularly, subjects can either take money for themselves or...

While politically attractive in order to generate tax revenues, the effects of a financial transaction tax (FTT) are scientifically disputed, not the least because seemingly small details of its implementation may matter a lot. In this paper, we provide experimental evidence on the different...

We investigate the influence of skewness in asset fundamentals on asset prices under different states of uncertainty in double-auction markets. Three different types of assets are considered: risky assets, ambiguous assets and assets where the fundamental value distribution can be learned by...

In laboratory experiments we explore the effects of communication and group decision making on investment behavior and on subjects’ proneness to behavioral biases. Most importantly, we show that communication and group decision making does not impact subjects’ overall proneness to biases...

We investigate the impact of trader and cash inflow on bubble formation in asset markets with a novel design featuring heterogeneous information and a constant fundamental value. Implementing seven treatments we find that (i) only the joint inflow of traders and cash triggers bubbles...

Contributions by investor-owned companies play major roles in financing the campaigns of candidates for elective office in the United States. We look at the presidential level and analyze contributions by companies before an election and their stock market performance following US presidential...

A symmetric distribution of information, although omnipresent in real markets, is rarely considered in experimental economics. We study whether information about imminent future dividends can abate bubbles in experimental asset markets. We find that markets with asymmetrically informed traders...

Trading in FX markets is dominated by two microstructures: exchanges with market makers and OTC-markets without market makers. Using laboratory experiments we test whether the impact of a Tobin tax is different in these two market microstructures. We find that (i) in markets without market...

How people are incentivized is one of the main drivers of how they behave. In laboratory asset markets we evaluate the impact of four trader incentive bonus, bonus with cap, linear, and penalty – on asset prices and trader behavior. We find that (i) an asset with identical expected dividend...
