Cigarettes are experience goods - most of their utility value only gets revealed when one consumes them. We hypothesize a three phase consumer life cycle for experience goods. Consumers initially do not know their utility from the good or their preferences for particular characteristics, and may...

A set of randomized experiments shed light on how markets and information influence household decisions to adopt nutritional innovations. Of 400 Indian villages, we randomly assigned half to an intervention where all shopkeepers were offered the option to sell a new salt, fortified with both...

We provide a general framework for incorporating many types of micro data from summary statistics to full surveys of selected consumers into Berry, Levinsohn, and Pakes (1995)-style estimates of differentiated products demand systems. We extend best practices for BLP estimation in Conlon and...

We use an experiment to test whether consumers optimally acquire information on energy costs in appliance markets where, like many contexts, consumers are poorly informed and make mistakes despite freely-available information. We find consumers acquire information suboptimally; there is little...

We study habitual brand loyalty, one of the earliest empirically-studied forms of switching costs and a classic source of structural state-dependence in consumer demand. Auxiliary instruments and economically-motivated restrictions can tighten nonparametric bounds on the extent of brand loyalty...

We study the long-run evolution of brand preferences, using new data on consumers' life histories and purchases of consumer packaged goods. Variation in where consumers have lived in the past allows us to isolate the causal effect of past experiences on current purchases, holding constant...
