We build a model of online behavioral manipulation driven by AI advances. A platform dynamically offers one of n products to a user who slowly learns product quality. User learning depends on a product's "glossiness,' which captures attributes that make products appear more attractive than they...

We investigate the short- and long-term effects of a natural gas boom in an economy where energy can be produced with coal, natural gas, or clean sources and the direction of technology is endogenous. In the short run, a natural gas boom reduces carbon emissions by inducing substitution away...

Building on theories of international relations, we analyze how mistrust (uncertainty about an adversary's preferences or capabilities), misperception (imperfect observation of an adversary's actions), and misunderstanding (non-degenerate higher-order beliefs) can lead to conflict and drive its...

To what extent, if at all, did employee-owned (EO) firms maintain jobs for workers compared to non-EO firms in the spring 2020 Covid-19 shock to the US economy? Did EO firms shift jobs from workplaces to work-from-home locations in the pandemic more or less than other firms? This paper uses a...

(1) The U.S. share of the world's science and engineering graduates is declining rapidly as European and Asian universities, particularly from China, have increased S&E degrees while US degree production has stagnated

We study the determinants of vertical integration in a new dataset of over 750,000 firms from 93 countries. Existing evidence suggests the presence of large cross-country differences in the organization of firms, which may be related to differences in financial development, contracting costs or...

The Journal of Labor Research 20th anniversary symposium review of What Do Unions Do? offers a unique opportunity to examine how the claims made in the book have fared in ensuing research and to ponder what parts of the book I would change if I could. This paper responds to the 18 critical...

We develop a tractable framework for the analysis of the relationship between contractual incompleteness, technological complementarities, and technology adoption. In our model a firm chooses its technology and investment levels in contractible activities by suppliers of intermediate inputs....

This paper shows that in the 2000s unions in the UK and US made innovative use of the Internet to deliver union services and move toward open source unions better suited for the modern world than traditional union structures. In contrast to analysts who see unions as being on an inexorable path...

The debate over the influence of labour market flexibility on performance is unlikely to be settled by additional studies using aggregate data and making cross-country comparisons. While this approach holds little promise, micro-analysis of workers and firms and increased use of experimental...
