Microcredit loans were traditionally extended to groups of people. However, there is no clear evidence that joint liability does lead to better borrower performance and recent years have seen a shift towards individual liability lending. Utilizing the exogenous shift from individual to joint...

We study a unique microcredit model with zero interest rate and voluntary contributions, used by Akhuwat, a microfinance organization operating in Pakistan since 2001. Borrowers are encouraged to give any amount they wish to the organization every month, in addition to the instalment for the...

This paper develops a novel method to identify the causal contribution of managers to team performance. The method requires repeated random assignment of managers to multiple teams and controls for individuals' skills. A good manager is someone who consistently causes their team to produce more...

I look at the effect of social status on transmission of pro-social behavior. In an artefactual field experiment conducted in northern Colombia I observe contribution to local biodiversity conservation. The design varies whether choice is observable or not and social status of observing/observed...

This paper investigates the interplay between cultural traditions and policy effectiveness. It explores the differential impact of a large development program (Cassa per il Mezzogiorno), implemented for four decades, starting in the 1950s, to stimulate convergence between Italy's South and the...

In this paper we examine the effects that variations in the quality of the environment at birth have on children's other-regarding preferences, as measured through four binary-choice dictator games run with school-age children in rural Sierra Leone. We examine the effect of exogenous variations...

We consider an expanded notion of social norms that renders them belief-dependent and partial, formulate a series of related testable predictions, and design an experiment based on a variant of the dictator game that tests for empirical relevance. Main results: Normative beliefs influence...

We investigate norms of corruption using the norm-elicitation procedure introduced by Krupka and Weber (2013). We use a within-subject design whereby the norms are elicited from the same subjects who are observed making choices in a bribery game. We test whether the order in which the...

We study whether leaders influence the unethical conduct of followers. To avoid selection issues present in natural environments, we use a laboratory experiment in which we form groups and assign leadership roles at random. We study an environment in which groups compete, with dishonest behavior...
