Organizations increasingly rely on teams to solve complex problems. The ability of teams to work well together is critical to their success. I experimentally test whether team performance is affected by whether team members like each other. I find that teams in which partners like each other do...

Die Untersuchung sozialer Ungleichheiten gehört zum Hauptgeschäft der Soziologie. Viele Ursache-Wirkungs-Mechanismen für Ungleichheitsphänomene sind gut erforscht, zumeist existieren alternative oder komplementäre Erklärungen für vorhandene Ungleichheiten. Aus dem Wissen, wie...

Is there a way of matching donations that avoids crowding out? We introduce a novel matching method where the matched amount is allocated to a different project, present some simple theoretical considerations that predict reduced crowding out or more crowding in (depending on the degree of...

While increasingly popular in many domains crowdfunding remains largely un-derresearched and little is known about the best way to encourage participation. In a field experiment we vary suggested amounts and test different wordings for a campaign to finance a club good - an institute's summer...

Multiple sources of funding are becoming increasingly important for charitable organizations. Donations from corporate donors for example account for 25-35% of charitable income for the largest US charities, across charitable sectors. This note presents some tentative first evidence from a...

We study intertemporal crowding between two fundraising campaigns for the same charitable organization by manipulating donors' beliefs about the likelihood of future campaigns in two subsequent field experiments. The data shows that initial giving is decreasing in the likelihood of a future...

We conduct a randomized field experiment to study the effects of two financial education interventions offered to small-scale retailers in Uganda. The treatments contrast "active learning" with "traditional lecturing" within standardized lesson-plans. We find that active learning has a positive...

Do contributions to online content platforms induce a feedback loop of ever more user-generated content or will they discourage future contributions? To assess this, we use a randomized field experiment which added content to some pages in Wikipedia while leaving similar pages unchanged. We find...

We conduct a field experiment where we vary both the presence of a gift-exchange wage and the effect of the worker's effort on the manager's payoff. Results indicate a strong complementarity between the initial wage-gift and the agent's ability to "repay the gift". We control for differences in...
