We survey the recent literature on corporate diversification. How does corporate diversification influence firm value? Does it create or destroy value? While, until the beginning of this century, the predominant thinking among researchers and practitioners was that corporate diversification...

We study the predictive ability of individual analyst target price changes for post-event abnormal stock returns within each recommendation category. Although prior studies generally demonstrate the investment value of target prices, we find that target price changes do not cause abnormal...

This paper is the first to provide evidence of efficient taxation of groups with heterogeneous levels of 'tax morale'. We set up an optimal income tax model where high tax morale implies a high subjective cost of evading taxes. The model predicts that 'nice guys finish last': groups with higher...

This paper investigates the impact of four key economic variables on an expert firm's incentive to defraud its customers in a credence goods market: the level of competition, the expert firm's financial situation, its competence, and its reputational concerns. We use and complement the dataset...

This paper investigates whether working under competitive or cooperative incentives affects deception in a subsequent, unrelated task. I use a laboratory study with two stages. First, participants work under a piece rate, tournament or team incentive in a real effort task. The second part...

This paper experimentally investigates into the effects of limited feedback on contributions in a repeated public goods game. We test whether feedback about good examples (i.e., the respective maximum contribution in a period) in contrast to bad examples (i.e., the minimum contributions) induces...

We propose a model for forecasting extreme electricity prices in real time (high frequency) settings. The unique feature of our model is its ability to forecast electricity price exceedances over very high thresholds, where only a few (if any) observations are available. The model can also be...

Recent discussions about rising inequality in industrialized countries have triggered calls for more government intervention and redistribution. Due to obvious behavioral effects caused by redistribution, it is however not clear whether redistributional policies are indeed able to combat...

In this article we develop a taxonomy of behavioral policy measures proposed by Thaler and Sunstein (2008). Based on this taxonomy, we discuss the ethical legitimacy of these measures. First, we explain two common reservations against nudges (choice architecture) rooted in utilitarian and...

In an experiment with professionals from the financial services sector, we investigate the impact of a team incentive scheme on recommendation quality of investment products when advisors benefit from advising lower quality products. Experimental results reveal that, when group affiliation is...
