Gone but not forgotten : labor flows, knowledge spillovers, and enduring social capital by Ajay Agrawal( Book )
11 editions published in 2003 in English and held by 41 libraries worldwide
Abstract: It is well known that patent citations occur disproportionately between patents issued to inventors living in the same location, which has been taken as evidence of geographically localized knowledge spillovers. In this study, we find that patent citations also occur disproportionately often in locations where the cited inventor was living prior to being issued the patent in question, which we interpret as evidence of a significant role played by social capital in promoting knowledge spillovers. We first develop a model of purposeful investments in social capital by co-located inventors that incorporates the effect of expected mobility. Using patent and citation data, we then test two hypotheses motivated by the model. First, we find strong evidence in support of the enduring social capital hypothesis; social ties that facilitate knowledge transfer persist even after formerly co-located individuals are separated. Consistent with the model, we find that individuals with higher ex ante mobility are somewhat less likely to invest in location-specific social relationships, but the pattern of spillovers implied by patent citations is consistent with them investing in those social relationships that survive subsequent geographic separation. Second, we find strong evidence that the social ties associated with co-location are particularly important for facilitating knowledge spillovers across technology fields or communities of practice where alternative mechanisms for transferring knowledge are more costly

Birds of a feather - better together? : exploring the optimal spatial distribution of ethnic inventors by Ajay Agrawal( Book )
7 editions published in 2007 in English and held by 20 libraries worldwide
"We examine how the spatial and social proximity of inventors affects knowledge flows, focusing especially on how the two forms of proximity interact. We develop a knowledge flow production function (KFPF) as a flexible tool for modeling access to knowledge and show that the optimal spatial concentration of socially proximate inventors in a city or nation depends on whether spatial and social proximity are complements or substitutes in facilitating knowledge flows. We employ patent citation data, using same-MSA and co-ethnicity as proxies for spatial and social proximity, respectively, to estimate the key KFPF parameters. Although co-location and co-ethnicity both predict knowledge flows, the marginal benefit of co-location is significantly less for co-ethnic inventors. These results imply that dispersion of socially proximate individuals is optimal from the perspectives of the city and the economy. In contrast, for socially proximate individuals themselves, spatial concentration is preferred - and the only stable equilibrium"--National Bureau of Economic Research web site
Brain drain or brain bank? : the impact of skilled emigration on poor-country innovation by Ajay Agrawal( Book )
8 editions published in 2008 in English and held by 9 libraries worldwide
The development prospects of a poor country depend in part on its capacity for innovation. The productivity of its innovators depends in turn on their access to technological knowledge. The emigration of highly skilled individuals weakens local knowledge networks (brain drain), but may also help remaining innovators access valuable knowledge accumulated abroad (brain bank). We develop a model in which the size of the optimal innovator diaspora depends on the competing strengths of co-location and diaspora effects for accessing knowledge. Then, using patent citation data associated with inventions from India, we estimate the key co-location and diaspora parameters; the net effect of innovator emigration is to harm domestic knowledge access, on average. However, knowledge access conferred by the diaspora is particularly valuable in the production of India's most important inventions as measured by citations received. Thus, our findings imply that the optimal emigration level may depend, at least partly, on the relative value resulting from the most cited compared to average inventions

The risk of social security benefit rule changes : some international evidence by John McHale( Book )
1 edition published in 1999 in English and held by 1 library worldwide
Against a background of projections of sharply increasing elderly dependency rates, workers in the major industrial economies are apprehensive that their social security benefit entitlements will be cut before or after they retire, leaving them with inadequate retirement income. This paper looks at recent benefit rule changes in the G7 countries to see what can be learned about such political risk in PAYG pension systems. From this small sample, I find that projections of rising costs under current rules are inducing reforms, and that these reforms often have a major impact on the present discounted value of promised benefits for middle-aged and younger workers. Usually, however, the benefits of the retired and those nearing retirement are protected. The phasing in of benefit cuts raises the question as to why younger workers are willing to take significant cuts in their implicit wealth while protecting the currently old. One possible answer is explored through a simple model: these workers fear even larger cuts in their benefits if the tax burden on future workers rises too high
Collaboration, stars, and the changing organization of science : evidence from evolutionary biology by Ajay Agrawal( Book )
4 editions published in 2013 in English and held by 1 library worldwide
We report a puzzling pair of facts concerning the organization of science. The concentration of research output is declining at the department level but increasing at the individual level. For example, in evolutionary biology, over the period 1980 to 2000, the fraction of citation-weighted publications produced by the top 20% of departments falls from approximately 75% to 60% but over the same period rises for the top 20% of individual scientists from 70% to 80%. We speculate that this may be due to changing patterns of collaboration, perhaps caused by the rising burden of knowledge and the falling cost of communication, both of which increase the returns to collaboration. Indeed, we report evidence that the propensity to collaborate is rising over time. Furthermore, the nature of collaboration is also changing. For example, the geographic distance as well as the difference in institution rank between collaborators is increasing over time. Moreover, the relative size of the pool of potential distant collaborators for star versus non-star scientists is rising over time. We develop a simple model based on star advantage in terms of the opportunities for collaboration that provides a unified explanation for these facts. Finally, considering the effect of individual location decisions of stars on the overall distribution of human capital, we speculate on the efficiency of the emerging distribution of scientific activity, given the localized externalities generated by stars on the one hand and the increasing returns to distant collaboration on the other

Why stars matter by Ajay Agrawal( Book )
4 editions published in 2014 in English and held by 1 library worldwide
The growing peer effects literature pays particular attention to the role of stars. We decompose the causal effect of hiring a star in terms of the productivity impact on: 1) co-located incumbents and 2) new recruits. Using longitudinal university department-level data we report that hiring a star does not increase overall incumbent productivity, although this aggregate effect hides offsetting effects on related (positive) versus unrelated (negative) colleagues. However, the primary impact comes from an increase in the average quality of subsequent recruits. This is most pronounced at mid-ranked institutions, suggesting implications for the socially optimal spatial organization of talent
