Research on networks of innovation has typically focused on relationships of competition and collaboration between firms in the network, sometimes extending the analysis to sources of new ideas such as universities. More recently, attention has been paid to the activities of intermediaries in such networks, which facilitate the innovation process, which are positioned between the sources and users of innovations. This paper focuses on the organization of a distinctive type of intermediary, which we have defined as an innovation broker, by providing an analysis of 10 case studies of organizations dedicated to innovation broking from around the world. Innovation brokers in our definition are organizations that are founded especially to undertake an intermediary role, rather than performing that role as a by-product of their principal activities. The results of this analysis suggest that the key role played by innovation brokers in the innovation process is the independent validation of new ideas, thereby facilitating diffusion. In order to carry out this task, innovation brokers are organized on a not-for-profit basis, typically as a public–private partnership. The paper concludes by discussing the implications of the findings for innovation theory and research in networks of innovation.  相似文献

An attempt is made in this article to redefine underemployment and unemployment without making reference to an excess supply of labor or any causal mechanism of unemployment. Instead, underemployment and unemployment are defined in terms of equity which draws upon the individual's preferences. A specific proposal is that underemployment be defined by the presence of contribution inequity relative to at least half the persons employed in a field that the underemployed person might prefer to move into. Empirically, most recent survey data on preferences for contingent and other nontraditional employment are used to illustrate the application of the concept. The major finding is that nearly 10 million Americans in the nontraditional workforce are underemployed.  相似文献

Abstract

Among the most controversial of public health measures are those that restrict people’s freedom of choice presumably for the purpose of protecting their own health and safety. Mandatory use of automobile seatbelts can inspire allusions to the “tyranny of health” and the ‘health police.” This study revisits state seatbelt legislation, which is in force in all but one state of the USA. In modeling seatbelt mandates as indefinitely repeated Prisoner’s Dilemma (PD) games, the study qualifies and overcomes the limitations of conventional interest group and expressive voting theories. It indicates why and how utility-maximizing players, particularly carmakers, insurance companies, consumer advocates and regulators, may choose to cooperate, even in instances where mutual defection would bring each of them higher payoffs. The study suggests why state seatbelt mandates endure, despite ongoing concerns that they undermine individual autonomy or that their social costs outweigh the benefits of law-enforcement. The evolution and mediating effects of reputation and reciprocity in otherwise highly contestable healthcare decisions are consequently explored. Finally, the study identifies the implications of indefinitely repeated games on the continuing nature of strategic relationships and for mitigating conflict over traffic safety regulation, regardless of time and place.  相似文献

This paper analyses the relationship between inflation and equity returns in Australia over the period January 1974 to March 1996. Analysis is based on monthly and quarterly data, using value weighted equity indices at both the aggregate market and industry level. Three price indices, the consumer price index (CPI) (quarterly) and the manufactured materials used index (MMU) and the manufacturing articles produced index (MAP) (both monthly and quarterly) are used to measure inflation. Results provide little evidence of the statistically significant negative relationship observed in the US for the full study period. Analysis is also conducted on three subperiods, ‘monetary targeting’ (July 1976–January 1985), ‘checklist approach’ (February 1985–December 1989) and anti-inflation (January 1990–March 1996). At the market level the anti-inflation subperiod does provide some evidence of a negative relationship between inflation and equity returns though statistical significance is not apparent with quarterly time series. The impact of expected inflation on industry returns varies considerably. Consistent with the overall market analysis, the incidence of negative expected inflation betas increases in the latter anti-inflation subperiod. Finally, changes in Government inflation policy appear to have greatest impact on industrial company expected inflation betas.  相似文献

An innovation which bypasses the need for instruments when estimating endogenous treatment effects is identification via conditional second moments. The most general of these approaches is Klein and Vella (J Econom 154:154–164, 2010), which models the conditional variances semiparametrically. While this is attractive, as identification is not reliant on parametric assumptions for variances, the nonparametric aspect of the estimation may discourage practitioners from its use. This paper outlines how the estimator can be implemented parametrically. The use of parametric assumptions is accompanied by a large reduction in computational and programming demands. We illustrate the approach by estimating the return to education using a sample drawn from the National Longitudinal Survey of Youth 1979. Accounting for endogeneity increases the estimate of the return to education from 6.8 to 11.2%.  相似文献

Why would potentially intolerant majorities in a democracy protect the rights of unpopular groups? This paper models the formation of legal standards that determine the extent of civil liberty in a society. It is shown that tolerant legal standards emerge over time, despite all individuals having intolerant preferences. Each period citizens choose activities that have social consequences. A majority vote determines which of these activities are legally protected. Because of errors in interpreting the symbolic content of these activities, voters from the majority will not impose excessively intolerant standards, otherwise they may end up severely punishing members of their own group by mistake.
Extending this framework to a dynamic model, we examine Markovian equilibria of the game when government improves with time in its ability to correctly interpret citizens' activities. These improvements allow an unchanging majority to impose increasingly intolerant standards over time. It is shown that societies with high political turnover due to population changes are apt to choose tolerant legal standards. Societies with low turnover are more apt to choose more intolerant and unstable ones. Each group seeks to prevent auditing capabilities of government from improving too much over time in order to prevent future majorities from successfully enforcing more intolerant standards.  相似文献
