For much of 2020, the COVID-19 epidemic upended social and economic life globally. In an effort to reduce COVID-19 risks in the U.S., state and local governments issued many recommendations and regulations to induce social distancing, adding to voluntary reductions in interpersonal contact. The...

We provide new theory and evidence on the role of consumption access in understanding the agglomeration of economic activity. We combine smartphone data that records user location every 5 minutes of the day with economic census data on the location of service-sector establishments to measure...

Costs of attention, while central to choice behavior, have proven hard to measure. We introduce a simple method of recovering them from choice data. Our recovery method rests on the observation that costs of attention play precisely the same role in consumer choice as do a competitive firm's...

After a discussion of cigarette smoking in the context of the Becker-Murphy (1988) model of rational addictive behavior, demand equations are derived accounting for the tolerance, reinforcement, and withdrawal characteristic of addictive consumption. These are contrasted to equations developed...

A common problem in household finance is that households are often inactive in response to incentives.

Subsidies to consumers may cause firms to charge higher prices, which offsets consumer benefits from subsidies. We study a subsidy program design that mitigates such price increases by making products' eligibility for a subsidy dependent on firms' commitment to price ceilings. To quantify the...

Many have argued that digital technologies such as smartphones and social media are addictive. We develop an economic model of digital addiction and estimate it using a randomized experiment. Temporary incentives to reduce social media use have persistent effects, suggesting social media are...

The COVID-19 pandemic has devastated many low- and middle-income countries (LMICs), causing widespread food insecurity and a sharp decline in living standards. In response to this crisis, governments and humanitarian organizations worldwide have mobilized targeted social assistance programs....
