Do consumers boycott in response to international conflict? We show that during the 2003 U.S.-France dispute over the Iraq War, the market share of French-sounding, U.S. supermarket brands declined. The dispute was a negative shock to U.S. consumers’ associations with France. French-sounding brands, which consumers perceive to be French imports but are not, allow us to isolate the dispute’s effect on economic behavior, as these brands’ only link to France is through consumers’ associations. Our estimates, derived from a nationwide sample of weekly supermarket sales for over 8, 000 brands, are robust to a variety of alternate explanations. We also show that supermarkets with a higher proportion of customers who are U.S. citizens (i.e., who more strongly identify with the U.S. national identity) exhibited sharper boycotts.

The authors assess how and why retailer-customized coupon campaigns affect customer purchases. The conceptual model proposes effects on trip incidence and revenues through the mere exposure to campaigns (exposure effect) and the redemption of coupons (redemption effect). The authors propose monetary savings of the coupons, regularity of the campaigns, and coupon fit with customer preferences as moderators. Analysis of data from a group of regional grocery chains that were part of a quasi experiment demonstrates that retailer-customized coupon campaigns have a positive exposure and redemption effect on customer purchases. Mere exposure to customized coupon campaigns contributes more than coupon redemption to campaign returns. Consistent with theoretical expectations, customized coupon campaigns are more effective if they provide more discounts, are unexpected, and are positioned as specially selected for and customized to consumer preferences. The substantial exposure effects suggest that managers should look beyond redemption rates and also consider sales lift from nonredeemers when measuring the effectiveness of customized coupon campaigns.

This research proposes a mechanism to develop long-term donor relationships, a major challenge in the nonprofit industry. The authors propose a metric, donation variety, which captures a donor's breadth of donations with a given nonprofit organization, controlling for the distribution of donations to different initiatives. Using donation data spanning 20 years from a major U.S. public university, the authors find that improvements in donation variety increase the likelihood that the donor will make a subsequent donation, increase the donation amount, and reduce the sensitivity of donations to negative macroeconomic shocks. In the acquisition phase, most donors give to a single initiative, and these decisions are more influenced by a donor's intrinsic motivations. In contrast, as the donor–nonprofit organization relationship develops over time, nonprofit marketing efforts have a more significant influence on a donor's decision to give to multiple initiatives. Finally, the authors conduct a field study that validates the econometric analysis and provides causal evidence that marketing efforts by nonprofit organizations can encourage donors to spread donations across multiple initiatives.
