This paper presents a model of private provision of a public good where individuals in a group have altruistic preferences and care about the private and public good consumption of the other members of the group. I show that increasing the level of altruism increases the Nash level of the public...

We study conflict between two groups of individuals. Using Schaffer's (1988) concept of evolutionary stability we provide an evolutionary underpinning for in-group altruism combined with spiteful behavior towards members of the rival out-group. We characterize the set of evolutionarily stable...

We conduct a large-scale survey experiment in nine European countries to study how priming a major crisis (COVID-19), common economic interests, and a shared identity influences altruism, reciprocity and trust of EU citizens. We find that priming the COVID-19 pandemic increases altruism and...

Recently, early investments in the human capital of children from socially disadvantaged environments have attracted a great deal of attention. Programs of such early intervention, aiming at children's health and well-being, are spreading considerably in the U.S. and are currently tested in...

Our experimental analysis of alliances in conflicts leads to three main findings. First, even in the absence of repeated interaction, direct contact or communication, free-riding among alliance members is far less pronounced than what would be expected from non-cooperative theory. Second, this...

The allocation of risk and of the income from risky investment and activities belongs to the central topics of international tax policy today. This fact is highlighted by the current BEPS initiative of G20 and OECD which casts doubt on the recognition of contractual risk allocation within...

This paper derives the optimal financial contract when an entrepreneur can evade taxes in a model of costly state verification. In contrast to previous literature on costly state verification and financial contracting, we find that standard debt contracts are not optimal when tax evasion is...

This paper analyzes corporate tax evasion in a principal-agent model with multitasking. A firm-owner hires a specialist tax manager who chooses the quantity as well as the quality of tax evasion. Higher quality is a form of self-insurance and lowers the firm's expected fine for tax evasion. In...

We study an all-pay contest with multiple identical prizes ("lifeboat seats"). Prizes are partitioned into subsets of prizes ("lifeboats"). Players play a twostage game. First, each player chooses an element of the partition ("a lifeboat"). Then each player competes for a prize in the subset...

I analyze whether or not a monitoring problem regarding abroad abatement can justify the import quotas on abroad emission certificates applied by several emission trading schemes. For this purpose I extend the Becker (1968) Crime and Punishment model by heterogeneity in the observability of...
