This paper connects ideas from recent literature on the economics of intellectual property (IP) to address the question: Did the strengthening and broadening of IP rights from important patent policy changes in the US promote greater innovation? The analysis rests on the theory of cumulative innovation, which shows that if IP rights on a pioneer invention extend to follow‐on research and impediments to contracting exist, then strengthening patents can actually reduce overall innovation. Recent empirical studies are consistent with the theory: patents can significantly deter follow‐on research in “complex” technology areas where contracting is difficult (computers, electronics, telecommunications) but not in drugs, chemicals and human genes. I outline remedies from court decisions and antitrust policy for addressing inefficiencies from patent trolling, patent thickets and the anti‐commons of fragmented ownership. I then apply the analysis to the antibiotics market, drawing on recent research, to examine how patent and competition policies can be used to improve incentives for drug development in the battle against antibiotic resistance. The literature provides persuasive evidence that the policy changes overreached in broadening and strengthening IP rights and reveals important patent reforms for improving the effectiveness of patent systems in the US and Canada.  相似文献

Using data on 1,360 savings and loan (S&L) institutions, we compare two non-parametric methods for measuring efficiency: data envelopment analysis (DEA) and algebraic methods based on Varian (1984). We show that both methods are vulnerable to measurement error, although both theoretically and empirically we find the Varian-style measures to be less vulnerable. Because we have data on the future insolvency of our S&Ls, we can directly compare the two methods by seeing which does a better job of predicting insolvency (working under the hypothesis that efficiency and insolvency should be negatively correlated). We find that various measures perform very similarly, except for the technical efficiency measure in DEA. Importantly, this last measure frequently yields the implausible result that efficiency and insolvency are positively correlated, possibly because it does not account for factor prices.  相似文献

In this paper we develop various measures of M&A failure for an intra‐European sample during the fifth takeover wave: inferior long‐term stock performance, inferior operating performance, and target divestment. After documenting the extent of M&A failure, we test the relation between short‐term abnormal returns at deal announcement and M&A failure. We examine a sample where listed bidders acquire listed targets (267 deals) as well as privately‐held targets (336 deals). Our results indicate M&A failure rates up to 50% in both samples. When acquirers and targets are listed, lower M&A announcement returns are consistently and significantly associated with higher M&A failure probabilities and long‐term losses. In contrast, when targets are privately held, we find no evidence of such an association.  相似文献

The zero-fare tour is a common phenomenon in China that receives a great deal of attention from the popular press but little attention in the tourism literature. This qualitative study illuminates the previously unheard voice of the zero-fare group tour guides, examining their work attitudes and relationships with tourists, tour operators, and tourism administrators. A two-phase pre- and post-interview approach is used to examine the impacts of the 2013 tourism law on the tour guides. Findings indicate that tour guides struggle with conflicting feelings towards the zero-fare tour and their place within it. For instance, the informants describe themselves as scapegoats of the zero-fare tour mode, yet they also enjoy the freedom and opportunity it presents. The study concludes with a call for more thoughtful consideration of the policy and governance of the zero-fare tour.  相似文献

This paper explores the nature of social capital arising from engagement in local festivals and the implications of this for the social sustainability of an emerging destination. Two case studies are developed from a longitudinal research project which investigates local festivals staged in the Hackney Wick and Fish Island area adjacent to Queen Elizabeth Olympic Park in East London, UK between 2008 and 2014. This area has been directly affected by extensive development and regeneration efforts associated with the staging of the London 2012 Olympic Games. The two festivals considered here respond to the challenges and opportunities arising for local people as the area changes. One festival aims to foster a sense of community by creating shared experiences and improving communication across diverse groups. The other draws together the cultural community, links them to the opportunities arising as the area emerges as a destination, and attracts visitors. These festivals increase social capital in the area, but its distribution is very uneven. The accrual of social capital exacerbates existing inequalities within the host community, favouring the “haves” at the expense of the “have nots”. There are tensions between the development of social capital and social sustainability in this emerging destination.  相似文献

Microdata sets—samples of data relating to individual reporting units—can provide a valuable extension of the national economic accounts as they presently exist, making it possible to meet many of the criticisms being leveled at the accounts over their failure to include much nontransactions information that is essential to the evaluation of economic and social performance. To serve this purpose, however, the microdata sets must be integrated with the aggregate accounts, and with one another. A microdata sets relating to any given sector should add up (with appropriate weighting) to the economic constructs for that sector in the national accounts, and the microdata set for one sector should be articulated as appropriate with those of other sectors. This paper discusses techniques for constructing such microdata sets, including necessary adjustments of the macro accounts, techniques of alignment of microdata with the macro accounts and the creation and development of synthetic microdata sets. Synthetic matching and other techniques of merging data sets are discussed. The paper concludes with a consideration of the methodological implication of the integration of microdata and national accounts.  相似文献

In a simulated cola taste test, experimenters' nonverbal behaviors influenced subjects' cola choices, although subjects expressed no awareness of the experimenters' impact. Nonverbal intimacy behaviors may make subjects feel comfortable in same-sex pairs and uncomfortable in mixed-sex pairs, resulting in an association of these internal states with cola preferences.  相似文献
