Innovations and their adoption are the keys to growth and development. Innovations are less socially useful, but more profitable for the innovator, when they are adopted slowly and the innovator remains a monopolist. For this reason, rent-seeking, both public and private, plays an important role in determining the social usefulness of innovations. This paper examines the political economy of intellectual property, analyzing the trade-off between private and public rent-seeking. While it is true in principle that public rent-seeking may be a substitute for private rent-seeking, it is not true that this results always either in less private rent-seeking or in a welfare improvement. When the public sector itself is selfish and behaves rationally, we may experience the worst of public and private rent-seeking together.  相似文献

In this paper we develop a framework for analyzing the political imperative. We argue that the effects of the political imperative on the firm will be a function of industry structure. Strategies that management employs in coping with the political imperative are a function of its impact on the firm and the firm's strategic predisposition. We also speculate on why strategic predisposition may lead firms to employ strategies that are not responsive to the demands of the political imperative.  相似文献

The paper assesses the merit of the view according to which the Bundesbank dominates monetary policy-making in the European Monetary System. Our tests give a strong rejection of German dominance and suggest, instead, that monetary policymaking in the EMS is interactive. There is evidence that the Bundesbank pursues her own policy goals in the longer run. But German independence does not imply German dominance.  相似文献

The enlargement of the European Union has increased concerns about the role of generous welfare transfers in attracting migrants. This paper explores the issue of welfare migration across the countries of the pre-enlargement European Union and finds a significant but small effect of the generosity of welfare on migration decisions. This effect, however, is still large enough to distort the distribution of migration flows and, possibly, offset the potential benefits of migration as an inflow of mobile labour into countries with traditionally immobile native workers.  相似文献

A total of 289 studies of returns to agricultural R&D were compiled and these provide 1821 estimates of rates of return. After removing statistical outliers and incomplete observations, across the remaining 1128 observations the estimated annual rates of return averaged 65 per cent overall — 80 per cent for research only, 80 per cent for extension only, and 47 per cent for research and extension combined. These averages reveal little meaningful information from a large body of literature, which provides rate-of-return estimates that are often not directly comparable. This study was aimed at trying to account for the differences. Several features of the methods used by research evaluators matter, in particular assumptions about lag lengths and the nature of the research-induced supply shift.  相似文献
