We examine the use of subsidies to research and development (R&D) in a mixed and a private duopoly market. We show that the socially optimal R&D subsidy is increasing in the degree of spillovers, but it is lower in the private duopoly. The optimal R&D subsidy leads to an increase in total R&D and production; however, it does not lead to the equalization of per firm output and therefore to an efficient distribution of production costs. We also find that privatization of the public firm reduces R&D activity and welfare in the duopoly market. This result stands even when optimal R&D subsidies are provided.  相似文献

The 1980s saw the need for change in the organizational role of human resource (HR) professionals, from the traditional employee champion and administrative expert to strategic business partner and change agent. The argument posited was that a more challenging environment compels organizations to turn to managing their HRs as a source of competitive advantage and that means an increasing business partnership for HR professionals. However, very few studies examine the execution of these multiple, sometimes contradictory roles, despite the risk that neglecting traditional roles endanger organizational performance in the long term. This five-country comparative study finds that multiple roles are at least moderately executed, and that these HR roles have different impact depending on the aspect of organizational performance. As well, a more challenging environment, defined here as legal constraints and industry challenges, generally does not have a significant moderating effect on the impact of the different HR roles on organizational performance.  相似文献

To advance theoretical understanding of consumer engagement on social media, this cross-cultural study evaluates how culture influences consumers’ engagement levels and activities on brand pages of social network sites. It further evaluates the underlying motivations and engagement mechanisms in two culturally distinct countries, China and the USA. Specifically, social media dependency, parasocial interaction, and community identification are examined as the key antecedents of consumer-brand engagement. The results confirm the effects of the proposed antecedents and reveal both cultural differences and similarities between Chinese and American consumers’ engagement with brand pages on social network sites.  相似文献

Applying value relevance analysis to a sample of European banks, we test the following: (i) the direct effects of the sustainability report on stock price; (ii) whether the report modifies the value relevance of financial accounting variables (indirect effects); and (iii) whether the value relevance of sustainability reports varies across countries. Results show that investors appreciate the additional and complementary disclosure provided by the sustainability report and that this disclosure produces a positive effect on stock prices. Estimates of the indirect effects demonstrate that it has a negative influence on book value per share, whereas the effect on earnings per share is not significant. Cross‐country analysis shows that the value relevance of the sustainability report varies across European countries, consistent with the hypothesis that the value relevance of the sustainability report is likely to be influenced by different institutional contexts.  相似文献

We analyze the impact of trade integration on plant TFP using Chilean plant-level data (1982–1999) and 3-digit bilateral trade flows. Our contribution is to disentangle the impact of export and import barriers, estimated as border effects within a multilateral context. A fall in export barriers is positively correlated with plant productivity in traded sectors. The reduction of import barriers, however, can only be associated to productivity improvements in export-oriented sectors. In import-competing sectors a robust positive correlation shows up between plant productivity and protection. We then test several channels linking trade integration and firm productivity.  相似文献

There is a rising trend among companies to publish their sustainability or corporate social responsibility (CSR) reports. Assurance of these reports is a valuable voluntary tool to provide them with higher credibility. Nonetheless, the quality of assurance reports differs in practice and the objective of this paper is to provide evidence in this new area of research. Indeed, we are pioneers in developing an index to measure the quality of assurance reports. We choose the Spanish setting because it is the worldwide leading country as regards CSR reporting (KPMG, 2011; Sierra et al., 2012). We have found evidence on the determinants for CSR reporting posited by existing literature that have an impact on (a) the decision of companies to publish their CSR reports, (b) the decision to assure the CSR report or not and (c) the decision to hire the assurance services from an auditor or a consultant and the subsequent quality of the assurance report. Last but not least, our results from a sample of 161 CSR assurance reports evidence that assurance reports are of fairly acceptable quality, according to the index proposed. Furthermore, the value of the quality index is significantly higher if the assurance services are provided by an auditor (as opposed to a consultant) and if the CSR reporting company is larger.

The airport problem is a widely studied allocation problem, with the aim of providing simple and fair sharing rule for the landing fees. In this note we introduce some fairness criteria and characterize the classical Baker-Thompson allocation rule.  相似文献

Modern science is characterized by an increasing trend in collaborations and interactions among researchers. This paper aims to analyse the effects of this phenomenon on the productivity of the science sector and on the growth rate of the economy. Basic research is modelled as a contest where only those who arrive first at an innovation obtain the reward and where the interactions among researchers do contribute to production of scientific knowledge. An important result is that when interactions are significant multiple steady states emerge. Hence the ‘science globalization’ process could have enhanced the heterogeneity among scientific sectors of different countries. When there are low interactions, policies that increase connectivity could have low or even perverse effect at improving the efficiency of science, the contrary happens in high connectivity environments.  相似文献
