We leverage newly linked data from the U.S. Census Bureau and the U.S. Bureau of Economic Analysis to study transactions within U.S. multinational enterprises (MNEs). We show that using administrative data on intrafirm trade allows us to correct for measurement error in survey data and to...

Persistence of sharecropping tenancy and increases in farm productivity following regulations protecting tenant rights have been observed in many developing countries. This paper examines if these can be explained by alternative models of sharecropping with two sided efforts/investments, namely,...

This paper considers the "DeFi intermediation chain"--the market structure that underlies the creation and distribution of ETH, the native cryptocurrency of Ethereum--to examine how information asymmetry shapes intermediation rents. We argue that using proof-of-stake blockchain technology in...

We analyze the offering, asking, and granting of help or other benefits as a three-stage game with bilateral private information between a person in need of help and a potential help-giver. Asking entails the risk of rejection, which can be painful: since unawareness of the need can no longer be...

I review and interpret two of Robert Engle's most important contributions: the theory and application of cointegration, and the theory and application of dynamic volatility models. I treat the latter much more extensively, de-emphasizing technical aspects and focusing instead on the intuition,...

Great scientific output typically peaks in middle age. A classic literature has emphasized comparisons across fields in the age of peak performance. More recent work highlights large underlying variation in age and creativity patterns, where the average age of great scientific contributions has...

Managers of private entrepreneurial firms face obstacles in raising capital both in placing a value on a firm and conveying value to investors. These problems are exacerbated when the firm is small, has limited assets (except for human capital) and has yet to have a lead product. In such cases...

This paper studies life cycle creativity among Nobel laureate economists. We identify two distinct life cycles of scholarly creativity. Experimental innovators work inductively, accumulating knowledge from experience. Conceptual innovators work deductively, applying abstract principles. We find...

The Nobel Prize in Physiology or Medicine is the most prestigious and coveted award in medical research. Anecdotal evidence and related research suggest that receiving it may adversely affect research productivity. We compared the post-Nobel research output of laureates (prize years: 1950-2010)...

This paper robustly concludes that it cannot. A model is constructed under idealised conditions that presume the risks associated with artificial general intelligence (AGI) are real, that safe AGI products are possible, and that there exist socially-minded funders who are interested in funding...
