Abstract: Trust is thought to be an important driver of economic growth and other economic outcomes. Previous studies suggest that trust may be a combination of risk attitudes, distributional preferences, betrayal aversion, and beliefs about the probability of being reciprocated. We compare the results of a binary trust game to the results of a series of control treatments that remove the...

Effective attention to information may play a prominent role in consumer choice for energy-intensive services and it may simply be a function of receiving timely information when consumption takes place.

Mobile money is an innovation that allows financial transactions to be performed via a cell phone. Even in poor regions of Africa, almost everyone has a cell phone; therefore, mobile money could both contribute to the continent’s economic growth and ensure that no Africans are excluded from access to financial services.

We run a randomized controlled trial (RCT) under which the treatment group receives a calendar designed to set savings goals and to make a plan to reach this goal. The control group is given a plain calendar. We find no average effect on savings, ...

About two billion people in the world do not own a financial account and there are many more who use financial services only occasionally. In the past, initiatives which address these problems of financial exclusion focused on the supply side of financial markets, in particular by increasing the branch network of banks and by offering cheap bank products. While this had the desired effect, recent ...
