Greenwood, Han, and Sanchez trace the VC industry's evolution from early angel networks like the Brush Electric Company through American Research and Development's 1956 investment in Digital Equipment Corporation, which returned 100% annually, to the limited partnership structure exemplified by Davis and Rock in 1961, which aligned incentives by paying general partners a management fee plus roughly 40% of capital gains. Regression analysis of US public companies from 1970 to 2014 shows VC-backed firms outperform non-VC-backed peers by 5.2 percentage points in R&D-to-sales ratio, 4.9 points in employment growth, 7.0 points in sales growth, and are valued 37.3% higher, though this advantage gradually shrinks over time after the IPO. Using an instrumental variable based on 1979 pension fund deregulation, the authors find a 10% increase in VC funding drives a 7.9% boost in patenting and 7.5% boost in quality-adjusted patenting within three years, while a one standard deviation rise in industry-level VC funding raises annual employment and sales growth by 1.3 and 1.9 percentage points respectively.

Policymakers in countries trying to build their own VC industries get a specific, empirically grounded case that VC financing causally drives measurable innovation and growth, not just correlates with it, using an instrumental variable strategy that addresses the obvious concern that VCs simply pick winning companies rather than actually improving them. The historical section is a genuinely useful primer for anyone trying to understand why the limited partnership structure became the dominant organizational form in venture capital, tracing the specific regulatory and tax incentives, capital gains treatment, pension fund deregulation, that shaped the industry into its modern form rather than assuming the structure was inevitable. Investors and researchers also get a specific quantitative benchmark for how quickly VC-backed advantage over non-VC-backed peers fades after IPO, which is a useful data point for anyone modeling how long a VC-related valuation premium should reasonably be expected to persist in a portfolio company after it goes public.
