The aim of this paper is to evaluate how immigration of high-skilled workers affects the technological-knowledge bias and, in turn, the skill premium in the host countries, in particular bearing in mind the recent experience in a number of European countries. We study a skill-biased dynamic general equilibrium R&D growth model in which the standard R&D technology is modified so wage inequality results from the direction of the technological knowledge, which in turn is induced by the price channel. By solving the transitional dynamics numerically, we show that the rise of the skill premium arises from the price-channel effect, complemented with a mechanism that reflects the impact of immigration on R&D. According to our quantitative results, our model is able to account for a significant proportion of the dynamics of the skill premium in the data for a number of European countries, thus, suggesting that differences in labour skills between immigrants and natives are, in practice, an important source of skill premium variation over time. 相似文献

This paper examines the uncertain information hypothesis on one major index and its corresponding exchange-traded fund: the
S&P 500 Index and SPDRs in the pre-SPDRs (01/63–12/93) and post-SPDRs (01/94–12/03) periods. Two strategies are used to measure
the economic significance of the uncertain information hypothesis. Overall, we present evidence confirming the uncertain information
hypothesis in the post-SPDRs period. However, we fail to convert the statistically significant gains observed into economic
gains under a conservative approach. In addition, the degree of difference in the volatilities of the 5-day post-event returns
(in both the S&P 500 and the SPDR) among the three subgroups diminishes in the post-SPDR period. Hence, we conclude that the
market is in fact short-term efficient in a more realistic setting. 相似文献

Through a convenience sample of 260 employees, the study shows how employees’ perceptions about corporate citizenship (CC)
predict their affective commitment. The study was carried out in Portugal, a high in-group and low societal collectivistic
culture. Maignan et al.’s (1999, Journal of the Academy of Marketing Science
27(4), 455–469) construct, including economic, legal, ethical, and discretionary responsibilities was used. The main findings
are: (a) contrary to what has been presumed in the literature, the discretionary dimension includes two factors: CC toward
employees and toward community; (b) perceptions of CC explain 35% of unique variance of affective commitment; (c) the best
predictors are perceptions of economic and legal CC and, mainly, perceptions of discretionary CC toward employees; (d) the
perceptions of discretionary CC toward employees are significantly better predictors of affective commitment than are perceptions
of economic, ethical, and discretionary CC toward the community; (e) perceived inconsistency of the several CC dimensions
is detrimental to employees’ affective commitment. The study questions the four-dimensional model of the CC construct as operationalized
by Maignan et al., suggests that culture should be included as a moderating variable in future research, and stresses that
affective commitment may decrease when employees perceive that their organizations act upon the several areas of CC inconsistently. 相似文献

Given the intense competition experienced in the sector, retailers have been designing strategies to create an environment conducive to consumer satisfaction and purchase, particularly in supermarkets and hypermarkets. This paper develops a conceptualization of customer satisfaction based on field data collected in a specialty store, focusing on the relative importance of the environmental factors on satisfaction. The results show that the most important environmental determinant of customer satisfaction is the variety of products. The help from employees, lighting, layout and design also stand out from the set of stimuli considered. 相似文献

The main objective of this paper is to analyse the competitiveness of the main maritime Port sited in Portugal - Port of Sines. This paper is developed under the resource-based view approach. A literature review about the resource-based view is presented with a special highlight on the contribution of organisation owns' resources to the competitiveness. With this study we intend to emphasize the applicability of a management theory to a different type of organisation which only recently starts to be preoccupied with its competitiveness. A case study methodology is used in order to collect all information needed about its main resources and capabilities of Port and also its competitiveness. The resources analysed in this paper are: The infrastructures, the accessibilities, the Port operations and also the information systems used on it. Also, a set of performance data is analysed as the main indicators of competitiveness. After that, a conceptual model is presented in order to systematise the main resources and capabilities under which the competitiveness of the Port of Sines is built on. 相似文献

The market value of U.S. corporations declined by 50% during 1973–74 and stagnated for the following 15 years. This abrupt decline in market valuations coincided with two technology shocks: (1) the start of the information technology revolution and (2) a sudden slowdown in productivity growth. I use general equilibrium theory to quantify the macroeconomic and asset price implications of these two shocks. The information technology revolution and the productivity slowdown make the theory consistent with the trends of key macroeconomic aggregates from the mid‐1970s to the 1990s, and can also account for most of the drop in market values. 相似文献

For a rather general class of risk-reserve processes, we provide an exact method for calculating different kinds of ruin probabilities, with particular emphasis on variations over Parisian type of ruin. The risk-reserve processes under consideration have, in general, dependent phase-type distributed claim sizes and inter-arrivals times, whereas the movement between claims can either be linear or follow a Brownian motion with linear drift. For such processes, we provide explicit formulae for classical, Parisian and cumulative Parisian types of ruin (for both finite and infinite time horizons) when the clocks are phase-type distributed. An erlangization scheme provides an efficient algorithmic methods for calculating the aforementioned ruin probabilities with deterministic clocks. Special attention is drawn to the construction of specific dependency structures, and we provide a number of numerical examples to study its effect on probabilities. 相似文献

A historical perspective of three export agro‐industries in Argentina (lemons, sweet citrus and tobacco) illustrates the range of factors that may foster subcontracting and the choice of subcontracting modalities. The case studies also illustrate that subcontracting is often a fragile strategy that leads to the eventual reabsorption of subcontracted tasks. We argue that the fragility of subcontracting the harvest rests on the inability of producers and labour contractors to negotiate a relationship that favours collaboration and problem solving. This failure is at the root of the high transaction costs of harvest subcontracting that force producers to resort to ancillary investments or sanctions, or to reabsorb some or all of the delegated tasks. A mismatch of resources and technical competence between producers and harvest labour contractors also contributes to inadequate performance of services. It is thus not surprising that harvest labour contractors are not always permanent fixtures; they may appear, disappear and reappear, particularly in fresh fruit export industries. 相似文献

ABSTRACT The authors studied how knowledge derived from firms’ relationships—the so-called second-hand knowledge—is likely to influence their internationalization process. In this article, they examine how a European producer of textiles is able to sell worldwide, including to China, a highly competitive player in this industry. This article discusses models of firms’ networks and the extent to which such networks generate important knowledge that can explain internationalization behavior—how it is able to influence the selection of foreign markets and the entry mode used. The authors use the revised version of the Uppsala model of internationalization, which emphasizes the roles of trust-building, knowledge, and creation of opportunities within relationships. 相似文献

Legislation outlined proposed changes in Galician Health Centres. This allowed us to set down the theory about personal and organizational Information–Influence Matrices and then Frameworks of Issues for the interactions between an individual Financial Manager and a Health Centre Co-ordinator, as well as the proposed organizational changes into a new system [Purdy DE, Gago S. Extending influence and accounting use: developing the frameworks to incorporate Galician legal matters about the proposed healthcare changes with managers and organizations for empirical study. Critical Perspectives on Accounting; in press].Evidence from a longitudinal study covering January 1997 and December 2001, indicated the suitability of these types of Matrices and Frameworks of Issues to analyse conversational data.Results agreed with anticipations at a personal level—wholly for a co-ordinator and partly for the Financial Manager. Differences between the findings and our anticipated Financial Manager's framework are straightforward and we have amended our Framework accordingly. The organization level has followed our anticipations though only 15% of Health Centres had continued with the new system, 85% remained working with the old system.Galician law contained aspirations for changing healthcare with autonomous Health Centres. Spanish health policies and budget laws have inhibited moves to change, as well as the actions of the professionals involved. 相似文献
