This paper undertakes econometric analysis of innovation, learning, and exporting in automobiles and electronics firms in China using a large-scale 2003 dataset to identify the most appropriate innovation proxy. Drawing on recent literature on innovation and learning in developing countries, it...

Research on intellectual property has focused on formal legally recorded rights that we call deeded, most often measured by granted patents. Meanwhile, other "defacto" IP (mainly purposive secrecy and natural excludability) has become more important because of the increasing closeness of...

This paper estimates quality and cost innovations in the early automobile, personal computer, rigid disk drive, computer monitor, and computer printer industries using industry-level data on firm numbers, price, quantity, and quality and an equilibrium model of industry evolution. The results...

The study analyses the market for semiconductor memory chips, in particular EPROMs. Semiconductors are very interesting industry for studying empirically the dynamics of innovation. Given the short product life cycles of generations of chips, the market dynamics unfold much more rapidly than in...

This paper examines exclusionary practices allegedly used by Intel to maintain its dominant position in sales of microprocessors for IBM-compatible personal computers (PCs), focusing primarily on the preferential allocation of scarce product among customers. The paper considers the period...

Among the main criticisms currently confronting the US Patent and Trademark Office are concerns about software patents and what role they play in the web of litigation now proceeding in the smart phone industry. We will examine the evidence on the litigation and the treatment by the Patent...

Metamorphic progress (productivity growth much faster than average) is often driven by Grilichesian inventions of methods of inventing. For hybrid seed corn, the enabling invention was double-cross hybridization yielding highly productive seed corn that was not self-propagating. Biotechnology...

The mobile applications (apps) industry has exhibited rapid entry and growth in the midst of a recession. Using unique data from the iPhone application ecosystem, we examine how the development of "killer apps" (apps appearing in the top grossing rank) varies by market and app characteristics....

When are technological laggards more likely to try to catch up with leaders? We offer empirical evidence on firm-level data of plant investments in the TFT-LCD panel industry, where technological competition has been intense and dynamic. We find that the followers' level of technology has a...
