We study whether individuals in a face-to-face situation can successfully exert some lying effort to delude others. We exploit data from a laboratory experiment in which participants were asked to assess videotaped statements as being rather truthful or untruthful. The statements are...

This paper studies how imposing norms on contribution behavior affects individuals' intrinsic motivation. We consider the church levy, which the Catholic Church in Germany collects as a charitable donation, despite the fact that the levy is legally a tax. We design a randomized field experiment...

We investigate the possibility that a decision-maker prefers to avoid making a decision and instead delegates it to an external device, e.g., a coin flip. In a series of experiments the participants often choose lotteries between allocations, which contradicts most theories of choice such as...

We study donor loyalty in the context of church membership in Germany. Church members have to make substantial payments to their church but can opt out at any time. In a large-scale field experiment, we examine how private recognition for past payments affects church members' loyalty. We find...

The market for private life annuities is characterised by adverse selection, that is, contracts offer lower than fair payoffs to individuals with low life expectancy. Moreover, life expectancy and income have been found to be positively correlated. The paper shows that a linear tax on annuity...

We investigate how personal income taxes affect the portfolio share of personal wealth that entrepreneurs invest in their own business. In a reformulation of the standard portfolio choice model that allows for underreporting of private business income to tax authorities, we show that a fall in...
