Smoking is the leading preventable cause of death in the U.S. Because e-cigarettes do not involve the combustion of tobacco, vaping offers the potential to prevent most of the health consequences of smoking. We study the impact of an information shock created by an outbreak of lung injuries...

This paper investigates a real-business-cycle economy that features dispersed information about the underlying aggregate productivity shocks, taste shocks, and, potentially, shocks to monopoly power. We show how the dispersion of information can (i) contribute to significant inertia in the...

The financial motivation to earn advertising revenue by spreading misinformation has been widely conjectured to be among the main reasons misinformation continues to be prevalent online. Research aimed at reducing the spread of misinformation has so far focused on user-level interventions with...

We review theoretical and empirical work on the economic effects of the United States and China trade relations during the last decades. We first discuss the origins of the China shock, its measurement, and present methods used to study its economic effects on different outcomes. We then focus...

Solar power is now economically competitive with fossil fuels in many countries, yet relatively few homeowners have installed solar panels on their property. A principal reason for this behavior stems from cognitive biases--such as myopia, inertia and herding--that cause consumers to avoid...

Regulatory review of new medicines is often viewed as a hindrance to innovation by increasing the hurdle to bring products to market. However, a more complete accounting of regulation must also account for its potential market expanding effects through quality certification. We combine data on...

The rapid diffusion and use of new ideas are critical for advancing and realizing the value of innovation. This paper explores the impact of demographic characteristics of innovators and potential adopters on the adoption of important new scientific ideas through networks. Using rich,...

Electric vehicles (EVs) powered by renewable electricity are a centerpiece of efforts to decarbonize transportation. EV advocates also claim benefits from local pollution reductions, lower life-cycle costs to consumers, and improved energy security. We examine the theory and evidence behind...

Why don't poor countries adopt more productive technologies? Is there a role for policies that coordinate technology adoption? To answer these questions, we develop a quantitative model that features complementarity in firms' technology adoption decisions: The gains from adoption are larger when...

This paper describes the adoption of automation technologies by US firms across all economic sectors by leveraging a new module introduced in the 2019 Annual Business Survey, conducted by the US Census Bureau in partnership with the National Center for Science and Engineering Statistics (NCSES)....
