Firms increasingly rely upon external actors for their innovation process. Interaction with these actors may occur formally
(i.e. through a collaboration agreement) or informally (i.e. external actors acts as sources of information). We analyze the
reasons why firms consider it to be important to develop formal and informal external linkages in the innovation process by
looking at the role played by firms’ innovative strategies and by taking into account the possibility that a complementarity
or substitutive relationship might exist between formal and informal linkages. Data are from the Third Community Innovation
Survey (CIS 3), where we have access to firm level micro-data from Sweden, Norway, the Netherlands and the UK. 相似文献

Abatement and Allocation in the Pilot Phase of the EU ETS 总被引:1,自引:1,他引:0
We use historical industrial emissions data to assess the level of abatement and over-allocation that took place across European
countries during the pilot phase (2005–2007) of the European Union Emission Trading Scheme. Using a dynamic panel data model,
we estimate the counter factual (business-as-usual) emissions scenario for EU member states. Comparing this baseline to allocated
and verified emissions, we find that both over-allocation and abatement occurred, along with under-allocation and emissions
inflation. Over the three trading years of the pilot phase we find over-allocation of approximately 280 million EUAs and total
abatement of 247 Mt CO2. However, we calculate that emissions inflation of approximately 73 Mt CO2 also occurred, possibly due to uncertainty about future policy design features. 相似文献

While anecdotal evidence suggests that interest groups play a key role in shaping immigration policy, there is no systematic empirical analysis of this issue. In this paper, we construct an industry-level dataset for the United States, by combining information on the number of temporary work visas with data on lobbying activity associated with immigration. We find robust evidence that both pro- and anti-immigration interest groups play a statistically significant and economically relevant role in shaping migration policy across sectors. Barriers to migration are lower in sectors in which business interest groups incur larger lobbying expenditures and higher in sectors where labor unions are more important. 相似文献

A continuing challenge for researchers and practitioners alike is the lack of data on the effectiveness of corporate–community
investment programmes. The focus of this article is on the minerals industry, where companies currently face the challenge
of matching corporate drivers for strategic partnership with community needs for programmes that contribute to local and regional
sustainability. While many global mining companies advocate a strategic approach to partnerships, there is no evidence currently
available that suggests companies are monitoring these partnerships to see if they do, in fact, represent ‘strategic’ investments.
This article argues that applying the management concept of ‘investment performance’ to corporate–community partnerships requires
questioning traditional evaluation methods that focus on the results of programmes or activities. We adopt a case study approach
to introduce an evaluation framework that considers performance from both corporate and community perspectives and that conceptualises
partnership performance as comprising four aspects: (1) the contribution of the partnership to the overall portfolio of a
company’s community investment programmes, (2) the appropriateness of the partnership model, (3) the effectiveness of the
partnering relationship and (4) the ability of the partners to achieve programme goals. The application of this evaluation
framework to an established corporate–community partnership programme provided some useful insights as to how partnership
performance can be improved. 相似文献

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

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
