Intellectual property rights are legal constraints that limit conditions of entry in industries where incumbents are innovators. The set of legal constraints is the same for all industries, and there is no consideration of the possibility that the externalities created by entry in a given industry may not necessarily be negative for the incumbent, or that the incumbent's R&D expenditures might actually be detrimental to new entrants. We show that one unique set of legal rules can foster innovation in some industries and be detrimental in others. Our model is illustrated by case studies from the Information and Communication Technologies industry. 相似文献

This article discusses the correlation between cascading subcontracting and employees' participation in continuing vocational training. Based on a capability approach, it uses the French quantitative linked employer–employee survey on training and career paths (DEFIS) to question to what degree inter‐firm relations influence their employees’ training opportunities and processes. The results suggest cascading effects in training participation, considered from the angle of taking part both in training and training decision making. It addresses public policy issues arising from inequalities in employee participation with respect to the subcontracting relationship and thereby questions the liability of pure principal contractors. 相似文献

We investigate the price discovery role of an exchange‐traded fund and the futures contract for the same market index. We find that the fund predicts the index in the subperiod after but not in the subperiod before a substantial decrease in the minimum tick size. The futures predict the index in both subperiods. The results are consistent with the view that the factors leading to successful price discovery do not depend on zero investment, as in futures markets, but do depend on a small tick size. © 2003 Wiley Periodicals, Inc.

This paper aims to study, in the most recent historical time period, the efficiency of the Paris Stock Exchange market. We
test its weak form while analysing the stock exchange returns series by nonparametric methods, using kernel methodology in
particular. In doing so, our approach extends the traditional view treating the observed cyclical fluctuations on this market. 相似文献

This article explores the differences between transnational and domestic terrorism, further differentiating by private versus government targets, to estimate the effect of exogenous catastrophic shocks on a country's level of domestic and transnational terrorism. The empirical analysis uses detailed data on terrorism, natural disasters, and other relevant controls for 176 countries from 1970–2007 to illuminate several key disparities in a postdisaster target choice of terrorists. The results indicate that natural disasters incite both transnational and domestic terrorism; however, evidence is found for dissimilar motivations between the two. While both types of terrorism increase after disasters, transnational attacks against the government increase immediately following the disaster, suggesting an impetus to exploit weakened “hard” targets during the chaos. Conversely, domestic terrorism against the government takes longer to manifest, suggesting a period of time for which the public recovers and assesses the government's response. 相似文献
