This paper characterizes inter-industry heterogeneity in rates of learning-by-doing and examines how industry learning rates are connected with firm performance. Using data from the US manufacturing sector, we measure the industry learning rate as the coefficient on cumulative output in a production function. We find that learning rates vary considerably(More)

Rather, we emphasize the importance of embedded relationships by individuals to effectively perform knowledge-generating activities. We rely on intraorganizational(More)

One of the most important aspects in the life cycle of EI is knowledge generation and flow, data management and information dissemination between ICT systems and(More)
This paper characterizes inter-industry heterogeneity in rates of learning-by-doing, and examines how industry learning rates are connected with firm performance. Using plant-level data from the US manufacturing sector, we measure the industry learning rate as the coefficient on cumulative output in a production function. We find that learning rates vary(More)
Despite the clinical relevance of the nails, the interpretation of the appearance of the nails is often neglected by clinicians and in medical training programs. To help overcome this we developed Nail-Tutor(TM), a personal computer program based on approximately 150 images that systematically teaches the anatomy, patterns of pathology, and diseases of the(More)
