I just learned that Nathan Rosenberg has passed away at 87. Nate was unarguably one of the most important economic historians and students of technological change of our era. He was also a one of the most important influences on my work.
I still regret that, out of ignorance, I didn’t take full advantage of all the resources available to me when I was a graduate student at Stanford. But Nate was a partial exception. I sat in on his course on history of economic thought; and when it came time to choose a thesis committee, he was kind enough to agree to be a member. I remember having a number of long conversations with him in his office in Encina Hall, although his greatest influence on me was through his writings. Nate had an eye for looking into — and theorizing about in a non-formal way — the micro structure of technology and innovation. I have always thought that his early work with Ed Ames is wonderful and greatly underappreciated. His work on the machine-tool industry in the United States is a progenitor of the economics of general-purpose technologies and one of the beginnings of what I like to think of as the Stanford School of technology-focused economic history.
I think Nate’s influence shows through on the range of my own work, including that with Paul Robertson. (It turns out that Nate was an associate advisor on Paul’s dissertation committee at Wisconsin before he was a member of mine at Stanford.) I was also fortunate to become part of the invisible college of technology economics of which Nate (along with Dick Nelson and others) was a dean, and I was fortunate to collaborate with other fellow Rosenberg students like David Mowery and Ed Steinmueller on policy-focused industry histories, another Rosenberg specialty.

Just ran across the abstract of a fascinating paper called “The Anti-Commons Revisited” by Jonathan Barnett at USC, which is forthcoming in the Harvard Journal of Law and Technology. Here’s the abstract.
Intellectual property scholars and policymakers often assert that technology and creative markets suffer from “anti-commons” (“AC”) effects that restrain innovation within a web of conflicting intellectual property claims. A minority view asserts that market players have incentives and capacities to correct for AC effects through transactional solutions. To assess the relative merits of each side of this debate, I review a large and diverse body of empirical evidence relating to AC effects in contemporary and historical markets. I independently replicate the most controversial empirical findings, supplement additional research on selected markets, and provide a survey of all documented IP-pooling arrangements in U.S. markets since 1900. The weight of the evidence strongly favors the minority view. Evidence for AC effects is scarce while evidence that markets correct for AC effects is abundant. AC effects are typically preempted or mitigated through cooperative arrangements among small numbers of IP holders or transactional solutions devised by entrepreneurial intermediaries for large numbers of IP holders. This pattern recurs over a diverse array of markets and periods, including automobiles, petroleum refining, aircraft, and radio communications in the early to mid-20th century, and information and communications technology markets from the late 20th century through the present. Contrary to standard assumptions, there is little evidence that these markets experienced reduced or delayed innovation or output despite intensive levels of patent issuance and litigation.

The new issue of Industrial and Corporate Change is a special issue devoted to the legacy of Steve Klepper, who died a couple of years ago at age 64. The editors provide a good survey of Steve’s work, and there are a number of interesting papers in the issue, including one by David Mowery comparing Klepper with Alfred Chandler.

Scientific progress, like economic progress, largely consists of combining and recombining existing resources and knowledge. At least that’s the way I interpret a new paper from Santa Fe Institute researchers Hyejin Youn, Luis Bettencourt, Jose Lobo, and Deborah Strumsky, “Invention as a Combinatorial Process: Evidence from US Patents” (via Steve Fiore):
Invention has been commonly conceptualized as a search over a space of combinatorial possibilities. Despite the existence of a rich literature, spanning a variety of disciplines, elaborating on the recombinant nature of invention, we lack a formal and quantitative characterization of the combinatorial process underpinning inventive activity. Here, we use US patent records dating from 1790 to 2010 to formally characterize invention as a combinatorial process. To do this, we treat patented inventions as carriers of technologies and avail ourselves of the elaborate system of technology codes used by the United States Patent and Trademark Office to classify the technologies responsible for an invention’s novelty. We find that the combinatorial inventive process exhibits an invariant rate of ‘exploitation’ (refinements of existing combinations of technologies) and ‘exploration’ (the development of new technological combinations). This combinatorial dynamic contrasts sharply with the creation of new technological capabilities—the building blocks to be combined—that has significantly slowed down. We also find that, notwithstanding the very reduced rate at which new technologies are introduced, the generation of novel technological combinations engenders a practically infinite space of technological configurations.
Or, as the Santa Fe press release puts it, “Most new patents are combinations of existing ideas and pretty much always have been, even as the stream of fundamentally new core technologies has slowed.” See also the authors’ earlier paper, “Atypical Combinations and Scientific Impact.”

The old Keynesian idea that war is good for the economy is not taken seriously by anyone outside the New York Times op-ed page. But much of the discussion still focuses on macroeconomic effects (on aggregate demand, labor-force mobilization, etc.). The more important effects, as we’ve often discussed on these pages, are microeconomic — namely, resources are reallocated from higher-valued, civilian and commercial uses, to lower-valued, military and governmental uses. There are huge distortions to capital, labor, and product markets, and even technological innovation — often seen as a benefit of wars, hot and cold — is hampered.
A new NBER paper by Zorina Khan looks carefully at the microeconomic effects of the US Civil War and finds substantial resource misallocation. Perhaps the most significant finding relates to entrepreneurial opportunity — individuals who would otherwise create significant economic value through establishing and running firms, developing new products and services, and otherwise improving the quality of life are instead motivated to pursue government military contracts (a point emphasized in the materials linked above). Here is the abstract (I don’t see an ungated version, but please share in the comments if you find one):
The Impact of War on Resource Allocation: ‘Creative Destruction’ and the American Civil War
B. Zorina Khan
NBER Working Paper No. 20944, February 2015
What is the effect of wars on industrialization, technology and commercial activity? In economic terms, such events as wars comprise a large exogenous shock to labor and capital markets, aggregate demand, the distribution of expenditures, and the rate and direction of technological innovation. In addition, if private individuals are extremely responsive to changes in incentives, wars can effect substantial changes in the allocation of resources, even within a decentralized structure with little federal control and a low rate of labor participation in the military. This paper examines war-time resource reallocation in terms of occupation, geographical mobility, and the commercialization of inventions during the American Civil War. The empirical evidence shows the war resulted in a significant temporary misallocation of resources, by reducing geographical mobility, and by creating incentives for individuals with high opportunity cost to switch into the market for military technologies, while decreasing financial returns to inventors. However, the end of armed conflict led to a rapid period of catching up, suggesting that the war did not lead to a permanent misallocation of inputs, and did not long inhibit the capacity for future technological progress.

Bryan Hong, Lorenz Kueng, and Mu-Jeung Yang have two new NBER papers on strategy and organization using a seven-year panel of about 5,500 Canadian firms. The papers exploit the Workplace and Employee Survey administered annually by Statistics Canada. The data, the authors’ approach, and the results should be very interesting to O&M readers. Here are the links to the NBER versions; there may be ungated versions as well.
Business Strategy and the Management of Firms
NBER Working Paper No. 20846, January 2015
Business strategy can be defined as a firm’s plan to generate economic profits based on lower cost, better quality, or new products. The analysis of business strategy is thus at the intersection of market competition and a firm’s efforts to secure persistently superior performance via investments in better management and organization. We empirically analyze the interaction of firms’ business strategies and their managerial practices using a unique, detailed dataset on business strategy, internal firm organization, performance and innovation, which is representative of the entire Canadian economy. Our empirical results show that measures of business strategy are strongly correlated with firm performance, both in the cross-section and over time, and even after controlling for unobserved profit shocks exploiting intermediates utilization. Results are particularly striking for innovation, as firms with some priority in business strategies are significantly more likely to innovate than firms without any strategic priority. Furthermore, our analysis highlights that the relationship between strategy and management is driven by two key organizational trade-offs: employee initiative vs. coordination as well as exploration of novel business opportunities vs. exploitation of existing profit sources.
Estimating Management Practice Complementarity between Decentralization and Performance Pay
NBER Working Paper No. 20845, January 2015
The existence of complementarity across management practices has been proposed as one potential explanation for the persistence of firm-level productivity differences. However, thus far no conclusive population-level tests of the complementary joint adoption of management practices have been conducted. Using unique detailed data on internal organization, occupational composition, and firm performance for a nationally representative sample of firms in the Canadian economy, we exploit regional variation in income tax progression as an instrument for the adoption of performance pay. We find systematic evidence for the complementarity of performance pay and decentralization of decision-making from principals to employees. Furthermore, in response to the adoption of performance pay, we find a concentration of decision-making at the level of managerial employees, as opposed to a general movement towards more decentralization throughout the organization. Finally, we find that adoption of performance pay is related to other types of organizational restructuring, such as greater use of outsourcing, Total Quality Management, re-engineering, and a reduction in the number of layers in the hierarchy.

Russ Coff has assembled an impressive list of syllabi and reading lists for PhD courses in strategy, innovation, research methods, and related subjects. Feel free to send him additional suggestions. Many useful references here for faculty and students teaching or taking these courses, and for anybody wishing to learn more about classic and contemporary literature in strategic management research.
