May 2017From Extreme to Mainstream: How Social Norms Unravel
with Leonardo Bursztyn, Georgy Egorov: w23415
Social norms are typically thought to be persistent and long-lasting, sometimes surviving through growth, recessions, and regime changes. In some cases, however, they can quickly change. This paper examines the unraveling of social norms in communication when new information becomes available, e.g., aggregated through elections. We build a model of strategic communication between citizens who can hold one of two mutually exclusive opinions. In our model, agents communicate their opinions to each other, and senders care about receivers' approval. As a result, senders are more likely to express the more popular opinion, while receivers make less inference about senders who stated the popular view. We test these predictions using two experiments. In the main experiment, we identify the causal...
Status Goods: Experimental Evidence from Platinum Credit Cards
with Leonardo Bursztyn, Bruno Ferman, Martin Kanz, Gautam Rao: w23414
This paper provides novel field-experimental evidence on status goods. We work with an Indonesian bank that markets platinum credit cards to high-income customers. In a first experiment, we show that demand for the platinum card greatly exceeds demand for a nondescript control product with identical benefits, suggesting demand for the pure status aspect of the card. Transaction data reveal that platinum cards are more likely to be used in social contexts, implying social image motivations. Combining price variation with information on the use of the card sheds light on the magnitude of the demand for social status. In a second experiment, we provide evidence of positional externalities from the consumption of these status goods. The final experiment shows that increasing self-esteem causa...
October 2015Moral Incentives: Experimental Evidence from Repayments of an Islamic Credit Card
with Leonardo Bursztyn, Daniel Gottlieb, Martin Kanz: w21611
We study the role of morality in the decision to repay debts. Using a field experiment with a large Islamic bank in Indonesia, we find that moral appeals strongly increase credit card repayments. In our setting, all of the bank’s late-paying credit card customers receive a basic reminder to repay their debt one day after they miss the payment due date. In addition, two days before the end of a ten-day grace period, clients in a treatment group also receive a text message that quotes an Islamic religious text stating that “non-repayment of debts by someone who is able to repay is an injustice.” This message increases the share of customers meeting their minimum payments by nearly 20%. By contrast, sending either a simple reminder or an Islamic quote that is unrelated to debt repayment has n...
