Alternatives to Punishment: The power to annul an economic exchange promotes self- rather than other-regarding preferences in fairness and trust games

Fairness and trust appraisals that engender economic exchange rely on thoughts about another person’s mind to satisfy self- (profit maximising) and other-regarding (social motives) preferences. Punishment should promote fairness and trust within economic exchange, guarding against free-riding and trust violations, but depends on other-regarding preferences concerned with the violator. Here, we explore an alternative to punishment that may instead promote self-regarding preferences—the opportunity for the decision-maker to annul (veto) the economic transaction. We test this veto approach by having participants assume the role of investor(s) in modified versions of the public goods (Studies one and three) and trust games (Studies two and four). Across four studies both online and in laboratory with two economic games, investor(s) could veto a transaction—annul a previous exchange—if the return from the other player(s) was deemed unsatisfactory. We find that this manipulation increased investment by the investor(s), consistent with games where second-party punishment is possible. Moreover, self-regarding preferences predicted veto behaviour, while other-regarding preferences predicted punishment behaviour. We argue that this veto approach can be an alternative to punishment that can safe-guard fairness and trust during economic exchange.

Going Far by Going Together: James M. Buchanan’s Economics of Shared Ethics

We explore themes in Nobel Prize–winning economist James M. Buchanan’s work and apply his Ethics and Economic Progress to problems facing individuals and firms. We focus on Buchanan’s analysis of the individual work ethic, his exhortations to “pay the preacher” of the “institutions of moral-ethical communication,” and his notion of law as “public capital.” We highlight several ways people with other-regarding preferences can contribute to social flourishing and some of the ways those who have “affected to trade for the public good” might want to redirect their efforts. We show how Buchanan’s work has considerable implications for business ethics. Just as his economic analysis of politics changed how we understand government, we think his economic analysis of ethics can (and should) change how we understand business.

Wearing a mask—For yourself or for others? Behavioral correlates of mask wearing among COVID-19 frontline workers

Human behavior can have effects on oneself and externalities on others. Mask wearing is such a behavior in the current pandemic. What motivates people to wear face masks in public when mask wearing is voluntary or not enforced? Which benefits should the policy makers rather emphasize in information campaigns—the reduced chances of getting the SARS-CoV-2 virus (benefits for oneself) or the reduced chances of transmitting the virus (benefits for others in the society)? In this paper, we link measured risk preferences and other-regarding preferences to mask wearing habits among 840 surveyed employees of two large Swiss hospitals. We find that the leading mask-wearing motivations change with age: While for older people, mask wearing habits are best explained by their self-regarding risk preferences, younger people are also motivated by other-regarding concerns. Our results are robust to different specifications including linear probability models, probit models and Lasso covariate selection models. Our findings thus allow drawing policy implications for effectively communicating public-health recommendations to frontline workers during the COVID-19 pandemic.

Class Altruism and Redistribution

Why do tax rates vary so much across countries? We study the role of other-regarding preferences and ethnic fragmentation in redistribution. A government is elected by altruistic voters and chooses a redistributive income tax. Altruism is directed toward social identity groups. Three main factors yield low levels of redistribution: (i) strong in-group altruism among rich voters—referred to as class altruism; (ii) weak universal altruism—in particular among the rich; and (iii) ethnic fragmentation among poor voters. We document survey evidence that the pattern of altruism in the United States and the European Union is consistent with the observed differences in taxes.

Optimal Incentives Schemes under Homo Moralis Preferences

This study focuses on the optimal incentive schemes in a multi-agent moral hazard model, where each agent has other-regarding preferences and an individual measure of output, with both being observable by the principal. In particular, the two agents display homo moralis preferences. I find that, contrary to the case with purely selfish preferences, tournaments can never be optimal when agents are risk averse, and as the degree of morality increases, positive payments are made in a larger number of output realizations. Furthermore, I extend the analysis to a dynamic setting, in which a contract is initially offered to the agents, who then repeatedly choose which level of effort to provide in each period. I show that the optimal incentive schemes in this case are similar to the ones obtained in the static setting, but for the role of intertemporal discounting.

Exploration in Teams and the Encouragement Effect: Theory and Experimental Evidence

This paper analyzes a two-person, two-stage model of sequential exploration where both information and payoff externalities exist and tests the derived hypotheses in the laboratory. We theoretically show that, even when agents are self-interested and perfectly rational, the information externality induces an encouragement effect: a positive effect of first player exploration on the optimality of the second player exploring as well. When agents have other-regarding preferences and imperfectly optimize, the encouragement effect is strongest. The explorative nature of the game raises the expected surplus compared with a payoff equivalent public goods game. We empirically confirm our main theoretical predictions using a novel experimental paradigm. Our findings are relevant for motivating and managing groups and teams innovating not only for private but also and especially so, for public goods.
