Since the mid 1990s the Indian pharmaceutical industry has emerged as a leading supplier of generic drugs to both developing and developed countries.The movement of the Indian pharmaceutical industry along the R&D value chain represents a remarkable shift from an importer to an innovator of drugs. The Indian government's industrial and technology policies along with changes in regulation of intellectual property rights played a crucial role in shaping this development of R&D capability. Using the 'capability creation model' this paper discusses the learning processes and stages involved in this dramatic accumulation of technological capability. This analysis shows that the Indian pharmaceutical industry has followed a trajectory from duplicative imitation to creative imitation to move up the value chain of pharmaceutical R&D. Finally as a result of changes in patent law the industry is learning to develop capabilities in innovative R&D. The basic and intermediate technological capabilities gained from imitative learning gave these firms a solid base for development of competence in advanced innovative R&D. These findings have implications for government policies as well as firm strategies in other developing countries albeit with some limitations due to global harmonisation of patent laws being promoted by the World Trade Organization.  相似文献

The recent financial crisis was triggered by large and unexpected losses on mortgages and mortgage‐related securities. Here we examine model risk arising from innovations in mortgage markets and the effect on asset values. In particular, we examine the effect of parameter instability in the prepayment function. Using carefully constructed microdata, we find that the refinancing propensity was greater in 1998 for a 1997 issue given the same incentives, compared to the 1993 performance of a 1992 issue. The associated change in cash flow patterns produces economically significant changes in asset prices. Results are robust to alternative term structure models.  相似文献

This study uses data for nearly 200 further education providers in England to investigate the level of efficiency and change in productivity over the period 1999–2003. Using data envelopment analysis we find that the mean provider efficiency varies between 83 and 90 percent over the period. Productivity change over the period was around 12 percent, and this comprised 8 percent technology change and 4 percent technical efficiency change. A multivariate analysis is therefore performed, which shows that, in general, student-related variables such as gender, ethnic and age mix are more important than staff-related variables in determining efficiency levels. The local unemployment rate also has an effect on provider efficiency. The policy implications of the results are that further education providers should implement strategies to improve the completion and achievement rates of white males, and should also offer increased administrative support to teachers.  相似文献

This research proposes and tests that regulatory foci of small business chief executive officers (promotion focus and prevention focus) relate to firm performance differentially when levels of environmental uncertainty vary. Results suggest that a promotion focus is positively related to firm performance, whereas a prevention focus is negatively related to firm performance. Further, these relationships are moderated by the degree of environmental dynamism such that in more dynamic environments, the relationship between promotion focus and firm performance is strengthened, whereas the relationship between prevention focus and firm performance is negatively affected. The reverse was found for less dynamic environments. Theoretical and practical implications as well as future research avenues are offered.  相似文献
