We estimate the effect of downsizing announcement on workplace performance using data from a German bakery chain of 193 shops. Faced with intensified competition, the firm decided to sell or close down 57 of its worst performing shops. We identify the effect of downsizing from a plausibly...

We test the effectiveness of team incentives by running a natural field experiment in a retail chain of 193 shops and 1,300 employees. As a response to intensified product market competition, the firm offered a bonus to shop teams for surpassing sales targets. A bonus to teams rather than...

We run two field experiments within a large retail chain showing that the effectiveness of performance pay crucially hinges on prior job experience. Introducing sales-based performance pay for district- and later for store-managers, we find negligible average treatment effects. Based on surveys...

In this paper, we investigate the effects of trade in foods on obesity in Mexico. To do so, we match data on Mexican food imports from the U.S. with anthropometric and food expenditure data. Our findings suggest that exposure to food imports from the U.S. can explain up to twenty percent of the...

Time scarcity is one of the strongest correlates of fast food consumption. To estimate the causal effect of time lost on food choice, we match daily store-specific foot traffic data traced via smartphones to plausibly exogenous shocks in highway traffic data in Los Angeles. We find that on days...

This paper derives the conditions under which fitness-reducing alleles can survive in a longrun stationary equilibrium for a trading population, extending the results in Saint-Paul (2002) for arbitrary systems of sexual reproduction

The slave trades out of Africa represent one of the most significant forced migration experiences in history. In this paper I illustrate their long-term consequences. I first consider the influence of the slave trade on the "sending" countries in Africa, with attention to their economic,...

This paper develops a model in which market structure is determined endogenously by the choice of intermediation mode. We consider two representative business modes of intermediation that are widely used in real-life markets: one is a middleman mode where an intermediary holds inventories which...

We econometrically evaluate the performance effects of a six month e-learning programme in a large retail chain with monthly data on sales revenue, for four years using panel regressions. Participants in early cohorts show positive performance effects during training periods that depreciate...

We use the exogenous assignment of Army personnel to duty locations to analyze the relationship between the characteristics of local markets and the propensity for consumers to be subjected to racial discrimination in their everyday commercial transactions. Overall, one in ten soldiers report...
