This article investigates patent citations made to published patent applications. Although citations to patent publications are conceptually indistinguishable from citations to granted patents, they are omitted from all standard measures. We find that publication citations are a large and growing portion of patent citations, and that they differ statistically from citations to granted patents on several important dimensions. We conclude that omitting publication citations is likely to generate biased measures, and that standard measures of patent citations should be corrected. We release our computer code and corrections for future use.
We investigate the extent to which loan officers generate individual effects on the design and performance of syndicated loan deals. We construct a novel database containing the identities of 6,821 loan officers involved in structuring syndicated loan deals. This data allow us to exploit movement of loan officers across banks to disentangle loan officer effects from bank fixed effects and estimate loan officers’ influence on both lending terms and loan performance. We find that loan officers have a significant influence on loan terms and loan performance that is incremental to bank and borrower characteristics.
We document that seasonal temperatures have significant and systematic effects on the U.S. economy, both at the aggregate level and across a wide cross-section of economic sectors. This effect is particularly strong for the summer: a 1F increase in the average summer temperature is associated with a reduction in the annual growth rate of state-level output of 0.15 to 0.25 percentage points. We combine our estimates with projected increases in seasonal temperatures and find that rising temperatures could reduce U.S. economic growth by up to one-third over the next century.
We examine how product market competition affects the disclosure of innovation. Theory posits that product market competition can cause firms to increase their disclosure of innovation to deter competitors. Consistent with this reasoning, we find that patent applicants in more competitive industries voluntarily accelerate their patent disclosures, which are credibly disclosed via the United States Patent and Trademark Office.
After years of decline, increases in American youth tobacco usage have pushed the tobacco control debate back into the forefront of the public health conversation. Youth tobacco use increased from 2011 to 2018, largely driven by e-cigarette usage, which grew from 1.5% to 20.8% of American high school students, representing an increase of 2.83 million adolescents. Despite extensive evidence that e-cigarette chemicals cause morbidity including immediate, harmful changes in endothelial function in healthy nonsmokers, 72% of teenage e-cigarettes users believe e-cigarettes cause some, little, or no harm.
In the run up to the financial crisis, the essential functions financial intermediaries played seemed to become less important. Commercial and industrial loans, as well as residential mortgages, the quintessential banking products, were securitized and sold.
We study how an improvement in contracting institutions due to the 1999 U.S.-China bilateral agreement affects U.S. firms’ innovation. We show that U.S. firms operating in China decrease their process innovations—innovations that improve firms’ own production methods—following the agreement.
Mergers and acquisitions (M&As) are an important mechanism through which new technology is adopted by firms. We document patterns of labor reallocation and wage changes following M&As, consistent with the adoption of technology. Specifically, we show target establishments invest more in technology, become less routine task intensive, employ a greater share of high technology workers, and pay more unequal wages.
Kenan Institute Executive Director and Institute for Private Capital Research Director Greg Brown gets the last word in this Bloomberg Businessweek article on the ubiquity of private equity.
Kenan-Flagler Business School professor and UNC Tax Center Research Director Jeff Hoopes comments on the intricacies of interpreting the president’s tax records if the push to release them ever comes to shove. Hoopes was quoted in this NPR article, which has been posted by more than 50 media outlets so far.
We find striking differences across economic states in how monthly and quarterly stock returns are related to changes in inflation expectations.
Marketers create social media, in the form of firm-generated content (FGC), to ignite interest in new products such as movies; in turn, there is a clear need to understand whether and how FGC influences demand. With a descriptive study, the authors investigate two potential mechanisms by which FGC may drive box office revenues.
Access challenges associated with high-cost pharmaceuticals have jump started discussion of solutions ranging from state-based boards reviewing drug price increases to harnessing Medicare’s purchasing power for “price negotiation” to old-fashioned price-setting.
We study dynamic decision-making under uncertainty when, at each period, a decision-maker implements a solution to a combinatorial optimization problem. The objective coefficient vectors of said problem, which are unobserved prior to implementation, vary from period to period.
This paper presents an easy-to-use measure of patent scope that is grounded both in patent law and in the practices of patent attorneys. We validate our measure by showing both that patent attorneys’ subjective assessments of scope agree with our estimates, and that the behavior of patenters is consistent with it.
As firms mature, their founders are often replaced with seasoned executives. When founders are retained, the surrounding top management team (TMT) members are viewed as critical resources in helping compensate for the founder's managerial deficiencies. Surprisingly, however, little is known about how TMT members affect a founder‐led firm's performance later in a firm's life.
Using U.S. venture capital investment data from 1985 to 2008 and qualitative interviews, we examine how group dynamics influence the growth of interorganizational collaborations through the addition of new members.
This study examines the importance of social perception of corporate social responsibility (CSR) and irresponsibility (CSI). Drawing from social psychology literature on stereotypes, we argue that two fundamental dimensions of social perception—warmth and competence—help explain the underlying processes and conditions under which CSR leads to specific outcomes.
We utilize the time period over which banking authorities discussed, adopted, and implemented Basel III to examine the financial reporting and operational decisions firms use to respond to proposed regulation. Our primary finding is that the banks affected by this proposal made strategic financial reporting changes and altered their business models prior to the regulation being enacted.
