We demonstrate how altruism can flourish in a population of nonaltruists. We assume that each individual plays a one-shot prisoner's dilemma game with his or her sibling and that the probability than an individual survives to reproduce is proportional to his or her payoff in this game. We model...

This paper analyses how neighbors' income affect agents' well-being using unprecedented data from the BRFSS and the City of Somerville. We conduct a multi-scale approach at the county, ZIP code and street-levels and find that the association between well-being and neighbors' income follows an...

This study analyses current energy projects in Benin, Burkina Faso, Niger and Togo. Based on the size of these projects, the study shows that currently, only small scale CDM projects can be developed in these countries in energy sectors. Moreover, baseline emissions factors are assessed for the...

This article uses survey data of workers in Japan to study the effects of own and self-reported reference wages on subjective well-being. Higher wages lead to higher life and job satisfaction. When workers perceive that their peers earn higher wages, they report lower well-being. We compare our...

For certain goods, higher levels of congestion imply higher levels of expected future entry costs. This provides current users of the good with an incentive to hoard, that is, to lengthen their duration of good use, in order avoid entry costs later on. We test for hoarding of university...

In uniform price, sealed-bid day-ahead electricity auctions, the market price is set at the intersection between aggregate demand and supply functions built by a market operator. Each day, just one agent - the marginal generator - owns the market-clearing plant. Day-ahead auctions are moreover...

This paper analyzes intertemporal effort provision in two-stage tournaments. A principal with a fixed budget for prizes faces two risk-neutral agents. He observes noisy signals of effort in both periods. His goal is to maximize either total efforts (perfect substitutes) or the product of first-...

This paper analyzes the evolution of wage inequality and wage mobility separately for men and women in West and East Germany over the last four decades. Using a large administrative data set which covers the years 1975 to 2008, I find that wage inequality increased and wage mobility decreased...
