Gift-giving customs are ubiquitous in social, political, and business life. Legal regulation and industry guidelines for gifts are often based on the assumption that large gifts have the potential to influence behavior and create conflicts of interest, but small gifts do not. However, scientific...

Building on theoretical and empirical literatures showing that choices not only reflect but also create preferences, we develop a two-stage incentivized intervention to promote pro-sociality. In the first stage, participants are incentivized to complete a compound task consisting of a targeted...

We conducted a randomized field experiment to examine how workers respond to wage cuts, and whether their response depends on the wages paid to coworkers. Workers were assigned to teams of two, performed identical individual tasks, and received the same performance-independent hourly wage....

We validate survey measures of social capital with a new data set that examines whether citizens report a lost wallet to its owner. Using data from more than 17,000 lost wallets across 40 countries, we find that survey measures of social capital - especially questions concerning generalized...

The literature on pro-social behavior shows that older children are more generous than younger children; however, the level of individual generosity is heterogeneous even between children of the same age. This paper investigates whether a child’s popularity affects a child’s generosity. Our...

We document the effectiveness of robo calls for increasing voter participation despite most published research finding little or no effect of automated calls. We establish this finding in a large field experiment in a targeted, partisan get-out-the-vote campaign. Our experimental design includes...

Political campaigns spend millions of dollars each voting cycle on persuading voters, and it is well established that these campaigns do affect voting decisions. What is less understood is what element of campaigning — the content of the message or the delivery method itself — sways voters,...

We examine gender differences in bargaining outcomes in a highly competitive and commonly used market: the taxi market in Lima, Peru. Examining the entire path of negotiation we find that men face higher initial prices and rejection rates. These differentials are consistent with both statistical...

Search frictions impede the labor market. Despite this indisputable fact, it is a priori unclear how job search costs affect search duration and unemployment: lower search costs make it easier to find a job, reducing search duration and unemployment, but may also increase the reservation wage,...
