The Effects of Social Networks on the Flow of International Students
Stuen, E. and Ramirez, S. The World Economy 42 (2), 509-529.
Results summary: The lagged share of international students from a particular origin country is a strong predictor of the flow of international students. This effect supersedes the otherwise powerful determinants of the wage differential and common language, when estimated with a multilateral panel. The results suggest that university and government policies that create international study opportunities for students from less-common nations will increase the subsequent flow of international students from those nations due to the role of social networks in transmitting information to potential students.

Morales, L.E., Hoang, N. and Stuen, E. Australian Journal of Agricultural and Resource Economics 61(4), 590-609.
Results summary: We applied Bayesian Structural Vector Autoregression models to the markets for beef in New South Wales and Queensland Australia. We confirmed not only that price shocks are transmitted between the two states in less than a week, but shocks to the price premium (i.e. the differential between high- and low-quality beef) are also transmitted. However, we also found a curious anomaly: shocks to the premium in Queensland resulted in a lower, not higher, premium in New South Wales. We attribute this asymmetry to structural features in the supply of cattle to abattoirs in Queensland: drought, transportation costs and long-term contracts.

University Reputation and Technology Commercialization: Evidence from Nanoscale Science
Lee, J. and Stuen, E. Journal of Technology Transfer, 41(3), 586-609.
Results summary: We investigate the propensity of university-affiliated scientists to commercialize discoveries without disclosing them to their university. We find that researchers are less likely to circumvent their institutions at more prestigious universities, and the greater the degree of revenue sharing from licenses held by the university.

An Analysis of Wine Critic Consensus: A Study of Washington and California Wines
Stuen, E., Miller, J. and Stone, R. Journal of Wine Economics 10(1): 47-61.
Results summary: Many recent studies have found little to no consistency in the ratings assigned to wines by judges and tasters. However, the only prior study to examine the consistency of the opinions of professional critics (Ashton, 2013) found a great deal of concordance among critics of Bordeaux wines. We replicate Ashton's approach but examine US-based critics and US wines. Like Ashton, we find a moderate degree of concordance between the wine scores (100-pt scale) of four different publications, based on measures such as the correlation coefficient, rank correlation and intraclass correlation. There may be no accounting for taste, but at least experts are somewhat consistent.

Doctoral Students and U.S. Immigration Policy
Maskus, K., A.M. Mobarak and E. Stuen. Science, 324: 562-563.
Results summary: We reviewed the literature on the economic benefits of a liberal policy toward foreign Ph.D. students, due to their contributions to science and innovation. Most of the evidence shows that doctoral students greatly enhance the conduct of science while students and contribute to innovation and competitiveness as immigrants after graduation.
Aggregate Evidence of Localized Academic Knowledge Transfer in the U.S.
Stuen, E. Economics Bulletin, 33: 1468-1478.
Results summary: In an analysis of panel data, I examined the correlation between academic publications and corporate patents within US metropolitan areas. The analysis confirmed the presence of academic knowledge transfers in the aggregate: elasticities on the order of 0.1 to 0.25 of corporate patenting with respect to university science. Policies that support basic research in universities generally lead to greater innovation in those universities' metropolitan areas and the formation of high-tech clusters.

Skilled Immigration and Innovation: Evidence from Enrolment Fluctuations in US Doctoral Programmes
Published version (gated) here
Final pre-publish version here
Stuen, E. T., Mobarak, A. M. and Maskus, K. E. The Economic Journal, 122: 1143–1176.
Results summary: We estimated the contributions to research productivity (measured in terms of publications and citations to those publications) of international and domestic Ph.D. students at 2,300 departments of science and engineering at US universities. Our panel spanned 1973 -1998, making use of information from before and after that period as well. We used information on shocks to enrollment to identify the causal effect of students on each department's research output. The marginal productivity of foreign students was statistically indistinguishable from that of US students: both estimated to be around 0.9 publications per student per year. Given the number of students per department, this effect accounts for about 2/3 of the average department's total productivity. We developed a model to understand how departments optimize enrollment of fee-paying versus scholarship students. The model shows that an equilibrium should arise in which departments admit both low-productivity fee-paying students and high-productivity scholarship students. Empirically, we find evidence of this by estimating models with instruments that differently shock the supply of fee-paying and scholarship students, and we found that enrollments induced due to changes in ability to pay did indeed have lower productivity. This raises a very salient policy concern: student visa policies that screen out low-income students (because they are more likely to eventually become immigrants) harm the research productivity of universities.
After publication the paper was recognized in several ways. The journal let us know that it had been shortlisted for the Royal Economic Society's Best Paper award of 2012. It was written about in the Times Higher Education, Science Careers and my co-author Mushfiq Mobarak was invited to write a column about it for the New York Times.
Mushfiq's column for the New York Times' Economix page, in which he highlighted our findings.
