We estimate the local spillovers from research university activity in a sample of urban counties. Our approach uses the interaction between university endowment values and stock market shocks over time for identification. We find statistically significant local spillover effects from university activity. The effects are significantly larger when local universities are more research intensive or local firms are technologically close to universities. Our results suggest that the longer-term effects that universities have on their local economies may grow over time as the composition of local industries adjusts to take advantage of the heterogeneous knowledge spillovers we identify.

We estimate the long-term effect of public R&D on growth in manufacturing by analyzing new data from the Cold War–era space race. We develop a novel empirical strategy that leverages US-Soviet rivalry in space technology to isolate windfall R&D spending. Our results demonstrate that public R&D conducted by NASA contractors increased manufacturing value added, employment, and capital accumulation in space-related sectors. While migration responses were important, they were not sufficient to generate a wedge between local and national effects. The iconic moonshot R&D program had only modest economic effects for both the local and national space-related sectors.

We use the late nineteenth-century establishment of agricultural experiment stations at preexisting land-grant colleges across the United States to estimate the importance of proximity to research for productivity growth. Our analysis reveals that proximity to newly opened permanent stations affected land productivity for about 20 years and then subsequently declined until becoming largely absent today. We conclude that spatial frictions substantially reduced the rate of return to public research spending in the late nineteenth and early twentieth centuries, but such frictions significantly diminished as extension programs, automobiles, and telephones made it easier for discoveries to reach farther farms.
