Innovation, Diffusion and Intellectual Property Rights
Our recent working paper studies innovation and diffusion of technology along an industry's evolution and characterizes how diffusion affects the incentives to innovate. In our analysis, firms participate in a competitive industry and face production capacity constraints. The entry of imitators thus increases industry supply and is socially beneficial to a degree. We show that, from the social welfare point of view, innovators should be compensated for intellectual property rights to internalize their knowledge spillovers to imitators. However, such compensation should be only partial due to ...

Innovation, Diffusion, and Trade: Theory and Measurement
I develop a multicountry-model in which economic growth is driven mainly by domestic innovation and the adoption of foreign technologies embodied in traded intermediate goods. Fitting the model to data on innovation, output per capita, and trade in varieties for the period 1996-2007, I estimate the costs of both domestic innovation and adopting foreign innovations, and then decompose the sources of economic growth around the world. I find that the adoption channel has been especially important in developing countries, and accounts for about 65% of their ?embodied? growth. Developed countries ...

The Effect of Vehicle Fuel Economy Standards on Technology Adoption
Many countries are tightening passenger vehicle fuel economy standards. The literature on passenger vehicle standards has used structural models to estimate their welfare effects. This paper provides the first empirical evidence on the effects of recently tightened fuel economy standards on technology adoption. Specifically, it investigates changes in the rate and direction of technology adoption, that is, the extent to which technology is used to increase fuel economy at the expense of other vehicle attributes. We find that recent U.S. and European standards have both increased the rate of ...
The Rapid Adoption of Generative AI
An analysis suggests that generative AI has been quickly and widely adopted at home and in the workplace, with about 40% of the U.S. population ages 18 to 64 using it to some degree.

Two-sided Market, R&D and Payments System Evolution
It takes many years for more efficient electronic payments to be widely used, and the fees that merchants (consumers) pay for using those services are increasing (decreasing) over time. We address these puzzles by studying payments system evolution with a dynamic model in a two-sided market setting. We calibrate the model to the U.S. payment card data, and conduct welfare and policy analysis. Our analysis shows that the market power of electronic payment networks plays important roles in explaining the slow adoption and asymmetric price changes, and the welfare impact of regulations may vary ...

The Rise of AI Pricing: Trends, Driving Forces, and Implications for Firm Performance
We document key stylized facts about the time-series trends and cross-sectional distributions AI pricing and study its implications for firm performance, both on average and in response to monetary policy shocks. We use the online job postings data from Lightcast to measure the adoption of AI pricing. We infer that a firm is adopting AI pricing if it posts a job that requires AI-related skills and contains the keyword “pricing.” At the aggregate level, the share of AI pricing jobs in all pricing jobs has increased more than tenfold since 2010. The rise of AI pricing jobs has been ...

The Rapid Adoption of Generative AI
Generative artificial intelligence (AI) is a potentially important new technology, but its impact on the economy depends on the speed and intensity of adoption. This paper reports results from a series of nationally representative U.S. surveys of generative AI use at work and at home. As of late 2024, nearly 40% of the U.S. population age 18-64 uses generative AI. Among employed respondents, 23% used generative AI for work at least once in the previous week: 9% used it every workday, and 14% on some but not all workdays. Relative to each technology's first mass-market product launch, work ...
