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...

In this paper we investigate the generalizability of the role of unequal opportunities and social group membership in redistributive preferences for the general population. We present results from a large-scale online experiment with more than 4,000 participants. The experiment consists of a...

By running a battery of incentivized and non-incentivized experiments with fund managers from four countries in the European Union, we investigate the impact of fund managers' cognitive skills and economic preferences on the dynamics of the mutual funds they manage. First, we find that fund...

To study whether clients benefit from delegating financial investment decisions to an agent, we run an investment allocation experiment with 408 finance professionals (agents) and 550 participants from the general population (clients). In several between subjects treatments, we vary the mode of...

We run an online experiment with finance professionals and subjects from the general population (clients) to examine drivers and implications of clients' delegation decisions. We find that clients favor delegation to investment algorithms, followed by delegation to finance professionals with...

Since the financial crisis, the behavior and personality traits of finance professionals have come under scrutiny. As comprehensive scientific findings are lacking, we run artefactual field experiments with finance professionals and a random sample of the working population to investigate...

The effects of a Tobin tax on foreign exchange markets have long been disputed. We present an experiment with currency trading on two markets, where either none, one, or both markets are taxed. Our results confirm the hitherto undisputed issues: a tax reduces trading volume, shifts market share...

In this paper we present results from experimental asset markets and simulations with traders who receive asymmetric information about the fundamental value of an asset. In the experimental markets with repetition insiders outperform the market and uninformed computerized random traders...

We study whether information about imminent future dividends can abate bubbles in experimental asset markets. Using the seminal design of Smith et al. (1988) we find that markets where traders are asymmetrically informed about future dividends have smaller, and shorter, bubbles than markets with...

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...
