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.

That’s the conclusion of a new NBER paper by Andy Young, Matthew Higgins, Don Lacombe, and Briana Sell, “The Direct and Indirect Effects of Small Business Administration Lending on Growth: Evidence from U.S. County-Level Data” (ungated version here). “We find evidence that a county’s SBA lending per capita is associated with direct negative effects on its income growth. We also find evidence of indirect negative effects on the growth rates of neighboring counties. Overall, a 10% increase in SBA loans per capita is associated with a cumulative decrease in income growth rates of about 2%.” As the authors point out, SBA loans represent funds that also have alternative uses, and SBA-sponsored clients may not be the most worthy recipients (in terms of generating economic growth).
The results are largely robust and, perhaps more importantly, we never find any evidence of positive growth effects associated with SBA lending. Even when the estimated effects are statistically insignificant, the point estimates are always negative. Our findings suggest that SBA lending to small businesses comes at the cost of loans that would have otherwise been made to more profitable and/or innovative firms. Furthermore, SBA lending in a given county results in negative spillover effects on income growth in neighboring counties. Given the popularity of pro-small business policies, our findings should give reason for policymakers and their constituents to reevaluate their priors.

At this week’s Strategic Management Conference in Madrid I participated in an interesting session on Media Innovations, along with Will Mitchell and Wiley’s Caroline McCarley. My remarks focused on academics and their use of social media. How (if at all) can professors use blogs, videos, wikis, and other social media products to disseminate their research, to improve their teaching, and even to discover new ideas? Are social media and “serious” activities like research and class preparation substitutes or complements? Should untenured faculty avoid such distractions?
I began my remarks — where else? — with Kim Kardashian. Biologist Neil Hall made a bit of a splash a few months back by introducing the Kardashian Index, basically the ratio of an academic researcher’s Twitter followers to citations in peer-reviewed journals. (For a rough approximation, just divide Twitter followers by Google Scholar cites.) Someone with a very high K-index, the story goes, has a large popular following, but hasn’t made any important scientific contributions — in other words, like Kim, famous for being famous.
Science published a rejoinder suggesting that the K-index gets it wrong by implying, incorrectly, that popular and scholarly influence are inversely related. Indeed, among the top 20 natural scientists, by Twitter followers, are some scientific lightweights like Neil deGrasse Tyson (2.4 million Twitter followers and 151 citations), but also serious thinkers like Tim Berners-Lee (179,000 followers and 51,204 cites) and Steven Pinker (142,000 and 49,933). I haven’t run the numbers for economists and management scholars but I think you’ll find the same general pattern. E.g., among the biggies on the LDRLB Top Professors on Twitter list you find a mix of practitioner-oriented writers with modest academic influence (Bill George, Richard Florida, Stew Friedman, Gary Hamel) and scholars with huge citation counts (Mike Porter, Clay Christensen, Adam Grant).
I went on to emphasize (as usual) that, for the most part, these issues are nothing new. Scholars and thinkers throughout history have used whatever media are available to disseminate their ideas to wider audiences. In the 17th-19th centuries there were pamphlets, handbills, newspapers, and lecture halls; in the 20th century radio, magazines, TV, and other outlets. Classical economists like John Stuart Mill published anti-slavery tracts; the Verein für Socialpolitik took positions on important social issues of the day; the American Economic Association was founded to combat lassiez-faire; C. S. Lewis gave his famous wartime radio lectures; Paul Samuelson and Milton Friedman dueled in the pages of Newsweek, and Friedman took to the airwaves for the PBS series “Free to Choose.” So academic bloggers, Tweeters, Facebookers, YouTubers, LinkedInners, and Instagrammers are following in a grand tradition. Of course, what’s new today is the scale; without a contract for a newspaper column or TV show, any of us can set up shop, and have the potential to reach a very wide audience. (more…)

Along with Gonçalo Pacheco de Almeida I am chairing the Competitive Strategy Interest Group Teaching Workshop at the upcoming Strategic Management Society conference in Madrid. The workshop is Saturday, 20 September 2014, 1:00-4:00pm at the main conference venue, the NH Eurobuilding, Paris Room. Our theme is “The Impact of New Technologies on Teaching and Higher Education” and we have an all-star lineup featuring Bharat Anand (Harvard), Peter Zemsky (INSEAD), Michael Leiblein (Ohio State), Michael Lenox (University of Virginia), Frank Rothaermel (Georgia Tech), Vivek Goel (Chief Academic Strategist at Coursera), and Andrea Martin (President of IBM Academy of Technology).
Background: The higher-education industry is abuzz with talk about MOOCs, distance learning, computer-based instruction, and other pedagogical innovations. Many of you are already using online exercises and assessments, simulations, and other activities in the classroom. How are these innovations best incorporated into the business curriculum, at the BBA, MBA, EMBA, and PhD levels? What can business scholars, say about the impact of these technologies on higher education more generally? Are they sustaining or disruptive innovations, and what do they imply for the structure of the business school, and the university itself?
The plan for this session is to discuss how leading companies and business schools are (a) driving innovation in the Higher Education teaching space, (b) thinking about the business model of virtual education (MOOCs, social learning, etc.), and (c) testing some of the assumptions behind globalization in the education industry.
The full schedule is below the fold. Additional information about the workshop, and the SMS itself, is available at the conference website.
If you’re coming to SMS this year, please plan to join us for the workshop. Pre-registration is encouraged but not required. If you’re planning to attend, please let us know by sending an email to firstname.lastname@example.org. Feel free to email Gonçalo or myself at the same address with questions or comments. (more…)
