We examine how firm age relates to innovtion quality, and how this relationship varies depending on the nature of technology. Using data on patents of COMPUSTAT firms, we find that firm age is negatively related to technical quality, and that this effect is greater in technologically active...

We investigate the impact of technological capability on firm market share using technology investment data in the global thin-film-transistor liquid-crystal-display panel industry from 1999 to 2007. The Arellano--Bond estimation of the dynamic panel model indicates that prior technological...

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...

This article uses data on transactions in the pharmaceutical industry to examine the demand-side of technology outsourcing. By integrating a transaction--cost economics perspective with the analysis of internal R&D capabilities, we find that firms with relatively more cospecialized complementary...

Prognostics & health management system is an integral component of any wind energy program to ensure high turbine availability and reliability. Traditional vibration-based condition monitoring practices have been proposed to be utilized with wind turbines as they have demonstrated varying...

Proper maintenance schedule is required to improve manufacturing systems’ profitability and productivity. A novel dynamic maintenance strategy is thus developed to incorporate both the single-machine optimization and the whole-system schedule for series–parallel system. Firstly, multiple...

We examine the impact of enforcing non-compete covenants (CNC) on the formation and performance of new firms using matched employer-employee data on 30 US states. To identify the impact of CNC, we exploit the inter-state variation in CNC enforcement along with the fact that courts do not enforce...

This note provides details about the construction of the NBER Patent Data-BR concordance, and is intended for researchers planning to use this concordance. In addition to describing the matching process used to construct the concordance, this note provides a discussion of the benefits and...

We propose an industry-level index of capital resalability-the share of used capital in aggregate industry capital expenditure-that relates (inversely) to sunkenness of investments. Using data from U.S. manufacturing, we then test the effect of capital resalability on industry productivity...
