I explore the prevalence of exchanges of innovation resources inside venture capital portfolios. I show that after companies join investors’ portfolios, several proxies of exchanges between them and portfolio companies (relative to matched nonportfolio companies) increase by an average of 60%. The increase holds when joining events are plausibly exogenous and when VCs’ bargaining power and potential conflicts of interest are low. Three novel mechanisms are supported: carve-outs, spawning, and recycling, whereby entrepreneurs divest innovation units, start new ventures, and reuse assets in other portfolio companies, respectively. Results suggest that returns to innovation are higher in venture capital portfolios

We study the international propagation of long-run risk in the context of a general equilibrium model with endogenous growth. Innovation and international diffusion of technologies are the channels at the core of our mechanism. A calibrated version of the model matches several asset pricing and macroeconomic quantity moments, alleviating some of the puzzles highlighted in the international macro-finance literature. Our model predicts that country pairs that share more research and development (R&D) have less volatile exchange rates and more correlated stock market returns. Using data from a sample of 19 developed countries, we provide suggestive empirical evidence in favor of our model’s predictions
