A migration network is modeled as a mutually beneficial cooperative agreement between financially-constrained individuals who seek to finance and expedite their migration. The cooperation agreement creates a network: "established" migrants contract to support the subsequent migration of others...

In many countries, schools have responded to the COVID-19 pandemic by splitting up classes. While the purpose of dividing classes is clearly health-related, the process of doing so poses an interesting question: what is the best way to divide a class so as to maximize the incentive for students...

Economic preferences - like time, risk and social preferences - have been shown to be very influential for real-life outcomes, such as educational achievements, labor market outcomes, or health status. We contribute to the recent literature that has examined how and when economic preferences are...

Drawing on two assumptions: that menopause is an instrument for the efficient regulation of the duration of a biologically expensive state, and that people have children in order to obtain support from them in old age, we set out a new idea that seeks to explain both the occurrence of menopause...

Under a deadweight loss of tax and transfer, there is tension between the optimal policy choices of a Rawlsian social planner and a utilitarian social planner. However, when with a weight greater than a certain critical value the individuals' utility functions incorporate distaste for low...

A transfer from a richer individual to poorer A transfer from a richer individual to poorer seems to be the most seems to be the most intuitive and straightforward way of reducing income inequality in a society. However, can such a transfer reduce the welfare of the society? We show that a rich...

In determining the optimal redistribution of a given population's income, we ask which factor is more important: the social planner's aversion to inequality, embedded in an isoelastic social welfare function indexed by a parameter alpha, or the individuals' concern at having a low relative...

This paper adds three dimensions to the received literature: it models migration when the individuals' preferences regarding their relative income are ordinal, it works out the resulting spatial steady state distribution of the individuals, and it shows that the aggregate of the individuals'...

We use queuing-related behavior as an instrument for assessing the social appeal of alternative cultural norms. Specifically, we study the behavior of rational and sophisticated individuals who stand in a given queue waiting to be served, and who, in order to speed up the process, consider...

We consider a tax-funded policy of admitting and integrating asylum seekers in a country in which the incomes of the native inhabitants are differentiated; for the sake of simplicity, we assume that there are just two groups of native inhabitants: high-income natives and low-income natives. As a...
