Knowledge that Transforms

We identify strong cross-border property rights as a driver for the globalization of innovation. Using 67 million patents from over 100 patent offices, we construct novel measures of the three stages of innovation diffusion: adoption, sourcing, and collaboration. Exploiting staggered bilateral investment treaties (BITs) as shocks to cross-border property rights, we show that signatory countries increase technology adoption and sourcing from each other; they also increase R&D collaborations. The results are particularly strong for countries with weak domestic institutions and technologies with high imitation risks. Increases in R&D-related foreign investments explain most of the results.

We consider a model in which the correlation between shocks to consumption and to expected future consumption growth is nonzero and varies over time. We validate this assumption empirically using the model’s implication that time variation in consumption growth persistence (CGP) drives the correlation between stock and bond returns. Our model implies that the stock–bond correlation is also related to the predictive relation between bond yields and future stock returns. Finally, we provide suggestive evidence that asset price fluctuations are the primary driver of changes in CGP.

We study when CEOs with legal expertise are valuable for firms. In general, lawyer CEOs are negatively associated with frequency and severity in employment civil rights, contract, labor, personal injury, and securities litigation. This effect is partly induced by the CEO’s management of litigation risk and reduction in other risky policies. Lawyer CEOs are further associated with an increase in gatekeepers providing additional legal oversight and a decrease in innovative activities with high litigation risk. Lawyer CEOs are more valuable during periods of enhanced compliance requirements and regulatory pressure and in industries with high litigation risk or better growth opportunities.

Using transaction-level trade data from China Customs and loan data from the China Development Bank (CDB), we find that CDB credit to strategic industries at the top of supply chains leads to lower prices, higher volume, and more product varieties and destinations for exports for firms in downstream industries. These positive spillovers stem from reduced intermediate goods prices and increased trade credit from upstream to downstream firms caused by CDB loans. Notably, this surge in import activity displaces U.S. firms within the same industry but bolsters downstream U.S. firms’ business performance and employment.

We develop an extensive mapping of the revolving door phenomenon by examining the work experience of 420,153 individuals in top corporate positions at 12,869 firms. More than half of these firms have at least one such individual with prior experience in one of 187 executive branch agencies. We find that firms are more likely to receive procurement contracts following the appointment of a former regulator transitioning within 2 years of leaving the agency, a result consistent with the “knowledge” hypothesis. Less-complex contracts signed following the appointment of former regulators are more likely to be renegotiated, increasing costs for the government.

We examine how lenders design contracts to account for transitory and permanent cash flow shocks facing borrowers. We find that volatile transitory cash flow shocks are associated with fewer liquidity covenants, indicating financial flexibility that enables firms to survive liquidity crunches. The opposite is true for volatile permanent cash flow, suggesting that borrowers’ economic fundamentals are important credit risk factors. Subsequent analyses show that borrowers exposed to transitory (permanent) shocks face less (more) severe credit consequences following poor performance. Overall, we show that transitory and permanent cash flow shocks have significant and opposite effects on debt contract covenant design.

Exploring the minimum wage policy discontinuities at county borders, we find that minimum wage hikes induce industrial firms to pollute more and reduce their abatement efforts. State ownership mitigates these negative effects, suggesting its role in addressing externality. The adverse environmental impacts are attenuated by the staggered increase in pollution discharge fees across provinces. These effects are stronger for firms with higher minimum wage sensitivity, lower market power, and greater financial constraints, and for firms that are the subsidiaries of nonlisted companies. Overall, our findings highlight the unintended environmental consequences of labor market policies.

This study examines whether and how corporate venture capital (CVC) spurs changes in firm scope. Using two text-based measures of firm scope, I provide evidence that CVC investments are strongly correlated with subsequent changes in firm scope among CVC parent firms, including seeding emerging businesses and creating new segments or divisions. Further evidence is consistent with an experimentation view, with more promising ventures having a stronger strategic impact on the scope changes of parent firms. Moreover, the study finds that post-CVC scope changes are primarily built internally and rarely involve killer acquisitions. These changes create value for CVC parents.

Using establishment-level data, we show that COVID-19 vaccinations boost business activity and firm performance in the United States. A 10-percent increase in vaccination rates results in a 4-percent to 6-percent increase in customer visits. We document the channels through which vaccinations increase store visits and the limits to the effect of vaccines on business activity. At the firm level, vaccinations increase sales and earnings, impact expansion decisions, and decrease probability of default, but the benefits vary across businesses. Vaccinations create private economic benefits to firms, shareholders, and employees, in addition to their intended public health benefits.

This article examines how realized variances predict cryptocurrency returns in the cross section using intraday data. We find that cryptocurrencies with higher variances exhibit lower returns in subsequent weeks. Decomposing total variances into signed jump and jump-robust variances reveals that the negative predictability is attributable to positive jump and jump-robust variances. The negative pricing effect is more pronounced for smaller cryptocurrencies with lower prices, less liquidity, more retail trading activities, and more positive sentiment. Our results suggest that cryptocurrency markets are unique because retail investors and preferences for lottery-like payoffs play important roles in the partial variance effects.
