We investigate the informativeness of hygiene signals in online reviews, and their effect on consumer choice and restaurant hygiene. We first extract signals of hygiene from Yelp. Among all dimensions that regulators monitor through mandated restaurant inspections, we find that reviews are more...

We exploit a quasi-experiment created when New York State began in 2011 to tax cigarettes sold on Native American Reservations. The regime change represents a unique opportunity to quantify brand loyalty because it almost doubled the price of premium-brand cigarettes, while Native brands were...

We study whether savings nudges have the unintended consequence of additional borrowing in high-interest credit. We use data from a pre-registered experiment that encouraged 3.1 million bank customers to save via SMS messages and train a machine learning algorithm to predict individual-level...

We study how Americans respond to idiosyncratic and exogenous changes in household wealth and unearned income. Our analyses combine administrative data on U.S. lottery winners with an event-study design that exploits variation in the timing of lottery wins. Our first contribution is to estimate...

The growth of the availability and use of detailed household financial transaction microdata has dramatically expanded the ability of researchers to understand both household decision-making as well as aggregate fluctuations across a wide range of fields. This class of transaction data is...

This paper estimates the impact on consumer behavior of a firm's voluntary disclosure of information. Specifically, we study the impact of Starbucks' disclosure of calorie information on its menu boards in June 2013. Using data on over 250,000 consumers' visits to specific restaurant chains, we...

New technologies have enabled firms to elicit granular behavioral data from consumers in exchange for lower prices and better experiences. This data can mitigate asymmetric information and moral hazard, but it may also increase firms' market power if kept proprietary. We study a voluntary...

The US trade war against China in 2018-2019 can either enhance or diminish the US soft power in China, depending on whether it is recognized as legitimate by Chinese citizens. We study how the viewership of US movies--an important element of the US soft power--is affected by the trade war,...

We investigate the relationship between (a) official information on COVID-19 infection and death case counts; (b) beliefs about such case counts, at present and in the future; (c) beliefs about average infection chance--in principle, directly calculable from (b); and (d) self-reported...

Using a large survey panel that connects household shopping behavior with individual health information, this paper documents correlations between self reported depression and the size and composition of shopping baskets. First, we find that roughly 16% of individuals report suffering from...
