Does Import Competition Spur Innovations?

چکیده
We examine the impact of import competition on firms’ innovation input and output. We conjecture that U.S. firms view import competition from high-wage countries (HWCs) as “neck-and-neck” competition and will respond by intensifying innovation. In contrast, U.S. firms will reduce innovation in response to import competition from low-wage countries (LWCs), because such competition does not always increase the potential benefits from innovation. Our empirical results are supportive. We find that, when confronting HWC import competition, U.S. firms increase R&D expenditures, file more patents, receive more citations to their patents, and produce more breakthrough patents. Moreover, U.S. firms closest to the technological frontier—largest firms, firms with the largest stocks of knowledge, and most profitable firms—intensify innovation the most in response to HWC competition. These results shed light on the relationship between product market competition and innovation, and on the impact of trade on firm performance.

متن کاملStrategic Renewal via Generational Product Innovation: The Impact of Market Concentration on Firms’ Responsiveness to Competitive and Complementary External Events
Generational product innovation (GPI) is an important but understudied form of strategic renewal strategy. The limited discussion of GPI in the organizational strategy literature argues that firms benefit from internally-driven GPI strategies, such as time-based pacing and serendipitous timing. While such internally-driven strategies may predominate when firms face diffuse competition, the lite...
متن کاملBeyond inducement in climate change: Does environmental performance spur environmental technologies?
This paper contributes to the debate on the inducement of environmental innovations by analysing the extent to which endogenous inducement mechanisms spur the generation of greener technologies in contexts characterized by weak exogenous inducement pressures. In the presence of a fragile environmental regulatory framework, inducement can indeed be endogenous and environmental innovations may be...

متن کاملA non-sperm transferring genital trait under sexual selection: an experimental approach.
Male genitalia are among the fastest evolving morphological characters, and at a general level sexual selection seems to be involved. But experimental determination of the functions of many remarkable genitalic elaborations is very rare. Here we present the first study to address experimentally the adaptive function of a male genital structure that is not involved in sperm transfer. Females of ...
