While policymakers often make bold claims as to the positive impact of intellectual property (IP) rights on both developed and developing country economies, the empirical literature is more ambiguous. IP rights have both incentive and inhibitory effects that are difficult to isolate in the abstract and are dependent on economic context. To unravel these contradictory effects, this article introduces an index that evaluates the strength of IP protection in 124 developing countries for the years 1995 to 2011. We illustrate the value of this index to economics study and show evidence that is consistent with IP leading to increased growth. Our results are further consistent with two causal pathways highlighted in the literature: that IP leads to greater levels of technology transfer and increased domestic inventive activity. Yet other aspects of our study fit uneasily with this simple story. For example, we find evidence suggesting that increased levels of growth lead to greater levels of IP protection, contradictory evidence in the literature linking IP with growth, a lack of evidence that increased levels of IP protection lead to actual use of the IP system, and problems with what IP indexes measure. Because of this, we suggest another – and so far undertheorized – explanation of the links between IP and growth: that IP may have few direct effects on growth and that any causality is a result of belief rather than actual deployment of IP.  相似文献

This final article is a synthesis of findings from the seven country studies in this special issue. Although there are characteristics common to all group systems, particularly those transitioning to democracy, there are also significant differences. Analysis of these differences reveals a direct relationship between both the level of socioeconomic and political development and the characteristics of the group systems in all Balkan countries. In addition, we provide new insights into group system development and operation. These are particularly related to the impact of war, inter‐ethnic cleavages, constitutional arrangements (majoritarian and consociational), economic crises, geopolitics, and the major presence of external interests.  相似文献

Based on data from two opinion surveys conducted in 2000 and 2008, this study shows that Hong Kong people have been consistently highly aware of the seriousness of different environmental problems and relatively pessimistic about the future resolution of these problems. Such pessimism is arguably related to their lack of confidence in the government's enforcement of environmental protection. Through an analysis of the environmental policy‐making and enforcement agency and three selected enforcement cases, the study further finds that the people's lack of confidence can be traced to the government's failure to bring about a comprehensive, integrated, far‐sighted environmental strategy with sophisticated institutional support and detailed enforcement mechanisms.
