Hire, Fire, or Train: Innovation and Human Capital Responses to Recessions
| Lasse Lien |
This is admittedly a shameless attempt to increase my human capital — by promoting the paper with the title above. The paper is joint work with Eirik S. Knudsen, and it is recently out in SEJ.
Abstract: We examine how firms’ relative emphasis on exploration and exploitation influence their human capital responses to recessions. We hypothesize and find that the higher the focus on exploration, the more firms invest in training, the more likely they are to hire, and the more likely they are to lay off employees during a recession. Finally, we also find that exploration-oriented firms are more likely to combine the accumulation of human capital through training, with both hiring and firing. This indicates that firms focusing on exploration more actively pursue the opportunities created by increased labor market imperfections during recessions. These results contribute to the literature by highlighting how recessions affect firms’ flow of human capital investments, and subsequently stocks, depending on their strategic orientations.

I Agree with Larry Summers
| Peter Klein |
Justin Fox reports on a recent high-powered behavioral economics conference featuring Raj Chetty, David Laibson, Antoinette Schoar, Maya Shankar, and other important contributors to this growing research stream. But he refers also to the “Summers critique,” the idea that key findings in behavioral economics research sound like recycled wisdom from business practitioners.
Summers [in 2012] told a story about a college acquaintance who as a cruel prank signed up another classmate for 60 different subscriptions of the Book-of-the-Month-Club ilk. The way these clubs worked is that once you signed up, you got a book in the mail every month and were charged for it unless you (a) sent the book back within a certain period of time or (b) went through the hassle of extricating yourself from the club altogether. Customers had to opt out in order to not keep buying books, so they bought more books than they otherwise would have. Book marketers, Summers said, had figured out the power of defaults long before economists had.
More generally, Fox asks, “Have behavioral economists really discovered anything new, or have they simply replaced some wrong-headed notions of post-World War II economics with insights that people in business have understood for decades and maybe even centuries?”
I took exactly the Summers line in a 2010 post, observing that behavioral economics “often seems to restate common, obvious, well-known ideas as if they are really novel insights (e.g., that preferences aren’t stable and predictable over time). More novel propositions are questionable at best.” I used a Dan Ariely column on compensation policy as an example:
He claims as a unique insight of behavioral economics that when people are evaluated according to quantitative measures of performance, they tend to focus on the measures, not the underlying behavior being measured. Well, duh. This is pretty much a staple of introductory lectures on agency theory (and features prominently in Steve Kerr’s classic 1975 article). Ariely goes on to suggest that CEOs should be rewarded not on the basis of a single measure of performance, but multiple measures. Double-duh. Holmström (1979) called this the “informativeness principle” and it’s in all the standard textbooks on contract design and compensation structure (e.g., Milgrom and Roberts, Brickley et al., etc.) (Of course, agency theory also recognizes that gathering information is costly, and that additional metrics are valuable, on the margin, only if the benefits exceed the costs, a point unmentioned by Ariely.)
Maybe Larry and I should hang out.
More on the Linear Model of Science and Technology
| Peter Klein |
As Joel Mokyr notes, one of Nathan Rosenberg’s important contributions was to debunk the “linear model” in which basic science begets applied science, which begets useful technology.
Technology in his view is not the mechanical “application of science” to production; it is a field of knowledge by itself, quite different in its incentives, its modes of transmission, and its culture. It is affected by science, but in turn provides “pure research” with its instruments and much of its agenda. In many cases, [Rosenberg] noted, scientists were confronted by the fact that things they had previously declared to be impossible were actually carried out by engineers and mechanics and had to admit somewhat sheepishly that were possible after all.
The same issue is raised in Margaret Jacob’s book The First Knowledge Economy: Human Capital and the European Economy, 1750-1850 (Cambridge University Press, 2014), which “argues persuasively for the critical importance of knowledge in Europe’s economic transformation during the period from 1750 to 1850, first in Britain and then in selected parts of northern and western Europe.” In other words, as noted by Erik Hornung:
She especially focusses on the marriage between theoretical sciences and applied mechanical knowledge which helped creating many technological innovations during the Industrial Revolution. She, thus, aims at rectifying the prevalent hypothesis that technological progress resulted from tinkering of skilled but science-ignorant engineers. An impressive set of new archival sources supports her argument that English engineers were, indeed, well aware of and heavily influenced by recent advances in natural sciences.
Mokyr on Rosenberg
| Peter Klein |
Further to Dick’s post on Nathan Rosenberg, here is an obituary from Joel Mokyr, who with Rosenberg’s passing is probably the most eminent living historian of innovation and technology. The review appeared on EH.Net.
The economic history profession has lost one of its most original, creative, and wide-ranging minds in the passing of Nathan Rosenberg on Aug. 24, 2015. Rosenberg was one of the founding fathers of Cliometrics, a member of the first group of Cliometricians that with coining the term “congregated at Purdue University in the late 1960s, and which included other luminaries among them Lance Davis, Jonathan Hughes, and Stanley Reiter (who is widely credited Cliometrics”). By 1970, this group had moved away from West Lafayette and dispersed to institutions such as Northwestern and CalTech. Rosenberg was hired by the University of Wisconsin, and was a member of a different group of influential and distinguished economic historians in Madison, including at one time or another Jeffrey Williamson, Peter Lindert, Morton Rothstein, Rondo Cameron, and Claudia Goldin. While at Wisconsin, Rosenberg was the editor of the Journal of Economic History and instrumental in its growing focus on the new economic history that was theoretically informed by economics and quantitatively more sophisticated — the very essence of the Cliometric Revolution.
In 1974, Rosenberg moved to Stanford, where he taught for more than a quarter century until his retirement in 2002. As department chair at Stanford between 1983and 1986 he helped build the department and maintain its position as one of the top economics departments in the country. Moreover, his leadership guaranteed that economic history remained an integral part of the undergraduate and Ph.D. programs and includes some of its most distinguished practitioners such as Gavin Wright and Avner Greif, as well as younger and promising scholars. Today, thanks to Rosenberg’s initiative and entrepreneurship, the Stanford department is housed in a gorgeous building named after Ralph Landau, whose support for research and teaching in economics was first stimulated by a fortuitous meeting with Rosenberg. The partnership with Landau, a chemical engineer and entrepreneur fascinated by economics, led to a fruitful scholarly collaboration between him and Rosenberg, especially in two well-regarded collections they edited together. Thanks in large part to Rosenberg’s resourcefulness, the graduate program at Stanford has thrived and produced many distinguished members of the economic history profession and applied economists working on innovation. While not all of them worked with him directly, his influence on the flourishing of economic history at Stanford was undeniable. Many of the former graduate students he trained and inspired co-authored and co-edited papers and books with him, such as David Mowery with whom he wrote Technology and the Pursuit of Economic Growth (Cambridge University Press, 1989). Without exception these young economists admired and adored him; two of them, Scott Stern and Shane Greenstein, were my former colleagues, and the three of us were instrumental in Northwestern awarding him an honorary doctorate in 2006, in the same class of honorary degrees as the then little-known junior senator from Illinois. If ever there was an academic conspiracy that can be called a true labor of love, this was it. (more…)
