We study the optimal allocation of R&D resources in an endogenous growth model with an innovation network, through which one sector's past innovations may benefit other sectors' future innovations. First, we provide closed-form sufficient statistics for the optimal path of R&D resource...

By thoroughly controlling for the country covariates, through a combination of matched sampling techniques with fixed-effect panel regression models, the analyses arrive at robust results across the various model specifications. First, national pharmaceutical patent protection alone does not...

Getting science policy right is a core objective of government that bears on scientific advance, economic growth, health, and longevity. Yet the process of science is changing. As science advances and knowledge accumulates, ensuing generations of innovators spend longer in training and become...

Evidence on the "funding gap" for investment innovation is surveyed. The focus is on financial market reasons for underinvestment that exist even when externality-induced underinvestment is absent. We conclude that while small and new innovative firms experience high costs of capital that are...

The expansion of U.S. universities after World War II gained from the arrival of immigrant scientists and graduate students, the broadening of access to universities, and the development of military research and high technology industry. Since the 1980s, however, growth of scientific research in...

Motivated by differences in R&D productivity across advanced economies, this paper presents an empirical examination of the determinants of country-level production of international patents. We introduce a novel framework based on the concept of national innovative capacity. National innovative...

How do import tariffs and R&D subsidies help domestic firms compete globally? How do these policies affect aggregate growth and economic welfare? To answer these questions, we build a dynamic general equilibrium growth model where firm innovation endogenously determines the dynamics of...

In this paper we document the patterns of labor market participation by women and ethnic minorities in venture capital firms and as founders of venture capital-backed startups. We show that from 1990-2016 women have been less than 10% of the entrepreneurial and venture capital labor pool,...

Research which explores unchartered waters has a high potential for major impact but also carries a higher uncertainty of having impact. Such explorative research is often described as taking a novel approach. This study examines the complex relationship between pursuing a novel approach and...
