In this article we re-examine the long-run sustainability of US budget deficits, using Bai and Perron's multiple structural change approach. While the deficit would have been weakly sustainable over the full sample (1947:1–2005:3), strong sustainability would appear only between January 1982 and February 1996. 相似文献

The World Bank has suggested the need to enhance Information and Communication Technology skills in all sectors because a 10% increase in internet connectivity was found to boost GDP growth by 1.38%. Simultaneously, the OECD argued that high internet access rates generate a 2% increase in GDP. Because the internet positively affects economic growth, we investigated the relationship between an economically active population, human capital and technology to evaluate these effects in Mexico. A data series from 1991 to 2010 was analysed in three stages according to the least-squares method. A Cobb–Douglas function under the Solow model was considered. Technology and internet access were found to positively affect top-level students and graduate students and thus contribute to the global innovation index. 相似文献

We make use of a data-set with both long span and high frequency to test for purchasing power parity (PPP) while allowing for a structural shift in the volatility of the Mexico–US bilateral real exchange rate (RER). The Kim, Leybourne and Newbold (2002) unit root test, robust to changes in the innovation variance, indicates mean stationarity of the monthly RER, and hence evidence of PPP, for the full sample, 1930–2012, and various subsamples. The persistence of deviations of the real rate from its PPP level as measured by half-lives ranges from 1.37 to 2.41 years. 相似文献

This article investigates the pair-wise convergence hypothesis of 17 Spanish regions with respect to the European Union (EU) and Euro-Zone (EZ). Several definitions of convergence are taken into account. The IB-MPI unit root testing procedure is then applied. A simultaneous approach based on the gap in levels and logs is developed to study convergence. The empirical results show incomplete catching-up in six cases with respect to both EU and EZ, and complete catching-up in nine with respect to EU and four with respect to EZ. When taking into account the behaviour of both gaps and loggaps, we further get four cases of cointegrated regions with respect to EZ and only one with respect to EU. Finally, there are four regions that diverge with respect to EU, but do converge with respect to the EZ. Only Baleares diverges with respect to both of them. 相似文献

We analyse the degree of polarisation in the international distribution of CO2 emissions per capita in the European Union. It is analytically relevant to examine the degree of instability inherent to a distribution and, in the analysed case, the likelihood that the distribution and its evolution will increase or decrease the chances of reaching an agreement on climate policy. Two approaches were used to measure polarisation: the endogenous approach, in which countries are grouped according to their similarity in terms of emissions, and the exogenous approach, in which countries are grouped geographically. Our findings indicate a clear decrease in polarisation since the mid-1990s, which can essentially be explained by the fact that the different groups have converged (i.e. antagonism among the CO2 emitters has decreased) as the contribution of energy intensity to between-group differences has decreased. This lower degree of polarisation in CO2 distribution suggests a situation more conducive to the possibility of reaching EU-wide agreements on the mitigation of CO2 emissions. 相似文献

Solar radiation management (SRM) technologies are considered one of the likeliest forms of geoengineering. If developed, a future generation could deploy them to limit the damages caused by the atmospheric carbon stock inherited from the current generation, despite their negative side effects. Should the current generation develop these geoengineering capabilities for a future generation? And how would a decision to develop SRM impact on the current generation’s abatement efforts? Natural scientists, ethicists, and other scholars argue that future generations could be more sanguine about the side effects of SRM deployment than the current generation. In this paper, we add economic rigor to this important debate on the intergenerational transfer of technological capabilities and pollution stocks. We identify three conjectures that constitute potentially rational courses of action for current society, including a ban on the development of SRM. However, the same premises that underpin these conjectures also allow for a novel possibility: If the development of SRM capabilities is sufficiently cheap, the current generation may for reasons of intergenerational strategy decide not just to develop SRM technologies, but also to abate more than in the absence of SRM. 相似文献

Based on the knowledge-based view of the firm, this paper analyses how alternative configurations of technological relatedness in interfirm research and development (R&D) alliances influence specific types of product innovation. A longitudinal study of pharmaceutical firms provides support for the argument that complementary alliances contribute to the development of both radical and incremental innovation. Collaborating with partners that have similar technologies only enhances incremental innovation, although its impact is curvilinear. These evidences highlight the importance of designing a suitable portfolio of R&D alliances in order to develop different innovative competences. 相似文献

Knowledge intensive services and, in particular, R&D services contribute significantly to innovation in firms. The objective of this paper is to find out which characteristics of firms explain the acquisition of R&D services and to analyse whether there are differences depending on the typology of the supplier (universities, technology centres and consulting firms). Three main conclusions emerge from the econometric estimations carried out with information from a survey of innovative firms in the region of Valencia in Spain. First, the results show that firm size and age matter in the decision to buy R&D services. Second, our results are consistent with the relevance that the literature gives to human capital in absorbing external knowledge. Third, innovation policy has a significant influence on the decision to acquire R&D services, particularly from universities and technology centres. 相似文献

Companies regard innovation as a central element of their business. However, as not all innovation types are the same, the central question is: should their announcements bring about the same effect on performance? This article analyses potential differences in firm value derived from the innovation-type announcements ‘R&;D’, ‘product’, and ‘process’, made by intensive news-generating firms such as biotech companies. The empirical application shows a significantly positive reaction to innovation announcements, with the prospect of future innovation (‘R&;D’ investment announcements) having greater impact on firm value than ‘product’ and ‘process’ innovations. Firm experience also acts as a moderator in this innovation–performance relationship, which is particularly relevant for entrepreneurs who need to develop and send credible signals indicating the value of the firm's intangible assets to the market. 相似文献

AbstractRetailers wish to expand their standard private label (PL) adopting a multi-tiered portfolio. We study the effects produced by the introduction of two new PLs quality-tiers (economy and premium) on the market share of various national brands (NB; premium-quality and second-tier) and the standard PL. This study proposes a model that accommodates three effects (similarity, attraction, and compromise) for understanding how the introduction of economy and premium PL may affect market incumbents. This study also analyzes the effects of introducing new PL quality-tiers for customer segments. Our results indicate that when economy and premium PL are introduced in the market, the choice probability of standard PL decreases, especially for high purchase quantity customers and PL loyal customers. In addition, introduction of a premium PL decreases the choice probability of second-tier NB and premium-quality NB, especially for PL loyal customers and high purchase quantity customers. 相似文献
