We examine the potential benefits of product piracy to entrepreneurial firms. Specifically, we use a resource-based perspective to show that a decrease in the inimitability of an entrepreneurial firm's intellectual property does not necessarily diminish performance when piracy increases the value of this resource, and an information economics perspective to explain why and when imitation can increase the value of an intellectual property resource. This explanation reconciles empirical studies that indicate mixed results. It also expands the resource-based view by suggesting that reducing the value of one resource can directly increase the value of another.  相似文献

Effective legal risk management is not a separate field of endeavor. Rather, it is inextricably linked with good management and with ethical management; managers who behave professionally and according to ethically defensible principles of action are quite unlikely to find themselves and their organizations stuck in a legal and/or ethical quagmire. Behavioral decision theory offers some explanations for why those managers who go astray do so, but explaining how basic human tendencies, uncorrected, may incline us to questionable decisions is not to justify such decisions. Managers who follow the guidelines set forth in this article may nonetheless find themselves or their companies under assault in the law courts or the court of public opinion, but should such an unlikely event occur, they will be far more likely to be able to successfully defend themselves.  相似文献

The value of involving students in research has been well documented. By including students in research, active and independent learning opportunities are provided, the importance of inquiry and investigation is emphasized, and connections between course material and the discipline become evident. Relevant opportunities for involving students in research projects can sometimes be elusive. Faculty time constraints limit the number of projects that can be undertaken and the number of students involved. Furthermore, many students become intimidated when told that they are required to carry out a research project. The purpose of this study was to use current consumer issues to involve undergraduate students in a relevant research project. The research project was implemented in class settings with teams of students. Faculty selected contemporary consumer issues based upon perceived student interest and experiences as consumers. By using issues of high relevance and familiarity to students and using the team approach within a course that faculty members were already assigned to teach, the issues of time constraint for the faculty members and increased levels of comfort for students were addressed. Prior to undertaking the project, students were instructed in appropriate research methods. Research methods utilized included student development of survey instruments, collection and recording of data, interpretation of data and presentation of results. Students became familiar with various research practices. By working as team members, the students’ comfort level for being involved in research increased; however, other common group challenges arose. Relevant, contemporary consumer issues carry high relevance and interest for student groups, helping generate enthusiasm for the research process. The focus on involving students in research continues to be emphasized. By using research topics related to student's experiences as consumers, students are more readily engaged in undertaking research projects. Through these relevant research projects, students’ consumer decision making is positively impacted.  相似文献

Branding studies, especially those focusing on brand extension, have often centered on establishing the relationship between consumer evaluation and the match between a product concept and the brand (concept congruity). This study introduces an additional type of congruity that arises in the evaluation of co‐branded products, the congruity between brand partners (between‐partner congruity). Between‐partner congruity has not previously been explicitly considered in the co‐branding literature, but is potentially an important influence on consumer perceptions of a brand partnership. Thus, this study represents an initial attempt to understand how the level of between‐partner congruity will affect consumer response to cobranded products. Several findings in the marketing literature have suggested that when respondents have the motivation to resolve incongruity, the relationship between congruity level and evaluation is nonmonotonic. In other words, moderately incongruent concepts are preferred to congruent or highly incongruent concepts to form an “inverted‐U” data function. Yet, when motivation to process is low, evaluation becomes less favorable in a linear fashion as incongruity increases. This study examines whether these findings can be extended to co‐branding. When concept congruity is controlled across brand pairs, the nonmonotonic relationship between between‐partner congruity level and product evaluation is observed when consumers are encouraged to elaborate on the rationale for the partnership (high involvement). However, when consumers attend to the global similarity of the partners (low involvement), product evaluation becomes less favorable as between‐partner incongruity increases. © 2007 Wiley Periodicals, Inc.  相似文献

Using a new dataset on imports of technology and total factor productivity (TFP) over 135 years for the OECD countries, this paper tests whether knowledge has been transmitted internationally through the channel of trade. The empirical estimates show that there is a robust relationship between TFP and imports of knowledge and that 93% of the increase in TFP over the past century has been solely due to imports of knowledge. Furthermore, it is shown that knowledge spillovers have been an important contributing factor behind the TFP convergence among the OECD countries over the period 1870 to 2004.  相似文献

I use records on commercial litigation in New South Wales to assess the role of norms and social capital during economic development. The data indicate that total disputes fell over time, whereas the rate of out of court settlements increased. Litigation rates were initially higher in frontier areas that arguably needed to adapt institutions to new circumstances because norms and standards were as yet undeveloped. The fraction of settled cases was significantly lower in frontier areas and areas without market access. Patterns related to jury trials, plaintiff recovery rates, and attorney representation are also assessed. The results are consistent with the theory that cooperative solutions emerge as areas gain access to markets, and suggest that order and law are complementary inputs into the process of economic development.  相似文献

Institutions and economic performance: evidence from the labour market   总被引:1,自引:0,他引:1  
We analyse the institutional determinants of economic performance,taking European labour-market institutions as a case in point.European economic growth after the Second World War was basedon Fordist technologies, a setting to which the continent'sinstitutions of solidaristic wage bargaining were ideally suited.They eased distributive conflicts and delivered wage moderation,which in turn supported high investment. The wage compressionthat was a corollary of their operation was of little consequenceso long as the dominant technologies were such that firms couldrely on a relatively homogeneous labour force. But as Fordismgave way to diversified quality production, which relied moreon highly skilled workers, the centralization of bargainingand the compression of wages became impediments rather thanaids to growth. Assuming that growth will rely even more inthe future on rapidly changing, science-based, skilled-labour-intensivetechnologies, countries with centralized labour-market institutionswill have to move still further in the direction of decentralization.Whether Europe in particular can accommodate these demands willhelp to determine whether it is able to re-establish a fullemployment economy in the twenty-first century.  相似文献

Summary In this paper a model of a closed economy, including a market sector and a public sector, is presented to analyse the consequences of a reduction of labour time with and without wage compensation. It turns out that a policy of labour time reduction without wage compensation is a very strong instrument to improve production and employment, if the economy is characterized by the Keynesiandemand model. But if the economy is characterized by the neoclassicalsupply model, a relatively large drop in wages is necessary to prevent a policy of labour time reduction from causing a process of stagflation.  相似文献
