This paper assesses the quantitative importance of electronic commerce in trade and tariff revenue, in light of the WTO decision on ‘duty‐free cyberspace’. Electronic commerce is likely to boost international trade in software, digitizable media products (music, books) and many services sectors significantly. However, despite the growing importance of electronic commerce for trade, tariff revenue loss from duty‐free electronic commerce is unlikely to be significant. 相似文献

The internationalization of firms through exports is often crucial to their survival and growth in this era of globalization. This is particularly the case for small and medium-sized enterprises (SMEs) operating in small and saturated markets, as is the case in Portugal. However, firms face several barriers to exporting, and this study aims to verify whether financial constraints influence a firm’s export propensity. The empirical analysis is based on a sample of 12,732 Portuguese manufacturing SMEs during the period 2008–2012, and tests two different proxies of financial constraints: the liquidity and leverage ratios. The results indicate that the SMEs in less healthy financial positions are less likely to export than the others are, although the impact of financial constraints on these Portuguese firms appears to be relatively small. 相似文献

Educational quality as perceived by the actors involved: reflections based on a study in the Environmental Sciences course 总被引:1,自引:1,他引:0
Training professionals for the new 21st century requires universities to make major changes in their conception of teaching,
which, through the active, committed participation of teachers and students, will lead to the building and developing of the
competencies needed by students for them to perform efficiently, ethically and with social commitment in their future jobs.
The participation of teachers and students and their commitment to quality in the teacher training process are essential elements
in the search for alternative ways to enhance university teaching. This article discusses the teacher training experiences
had by the author in the ICE of Madrid Polytechnic University with the inclusion of data from a study undertaken on the Environmental
Sciences course of this university where teachers, students and postgraduates’ perception of the quality of their vocational
training at university is an important starting point for the design of strategies aimed at enhancing the quality of teaching. 相似文献

In this study we examine regional data on per worker GDP, disaggregated at sectoral level, by focusing our interest on the
role of differences in the sectoral composition of activities, and in productivity gaps that are uniform across sectors, in
explaining the catching-up process, which is realized through physical and human capital as well as technological knowledge
accumulation. Our objective is to investigate how much of the interregional inequality in aggregate productivity per worker
is imputable to each component. A methodology for identifying and analyzing sources of inequality from a decomposed perspective
is developed in the growth framework by combining a shift-share based technique and a SUR model specification for the conditional-convergence
analysis. The proposed approach is employed to analyze aggregate interregional inequality of per worker productivity levels
in Italy over the period 1970–2000. With respect to the existing empirical results, our approach provides a more comprehensive
and detailed examination of the contribution of each identified component in explaining the regional productivity gaps in
Italy. It is argued that region-specific productivity differentials, uniform across sectors, explain a quite large share of
differences in productivity per worker. However, sectoral composition plays a non negligible role, although decreasing since
the end of 1980s, and very different productivity patterns emerge within geographical areas.

ABSTRACTThere is growing evidence that nature-based recreation (NBR) during childhood promotes connectedness to nature, which in turn fuels NBR during adulthood. In addition to providing a number of health benefits, NBR participation may enhance leisure satisfaction, an important predictor of happiness and life satisfaction. In this exploratory study, we tested these hypothesised links using a path model with a cross-sectional sample of 224 Brazilian college students, where NBR participation during childhood increases connectedness to nature and NBR participation during adulthood, which in turn promotes leisure satisfaction. The model fit the data well χ2 (2) = 1.924, χ2/df = 0.962 (N = 220, p = .38), CFI = 1.00, AGFI = .978, GFI = .996, and RMSEA = .00, with results showing an indirect positive link between NBR during childhood and leisure satisfaction, and a direct link between NBR during adulthood and leisure satisfaction. The indirect effect of connectedness to nature on leisure satisfaction was also significant: NBR during childhood fostered connectedness to nature, which motivated NBR during adulthood and higher levels of leisure satisfaction. Leisure practitioners can improve people’s leisure satisfaction by promoting engagement in NBR activities across life stages and emphasising connection to nature. 相似文献

From December 1999, shareholders who disposed of shares in Australian takeovers in exchange for scrip could elect to defer capital gains taxation until the disposal of the shares received. We investigate payment method choice by acquiring firms before and after this regulatory change to assess whether target shareholder capital gains tax liabilities became an important factor considered in choosing the form of payment. The results show that, subsequent to the regulatory change, there is a significantly higher probability that equity will be offered as consideration where target shareholder capital gains are greater. This finding confirms the importance of shareholder level taxation in explaining corporate acquisition structure and adds to previous European and US evidence on factors associated with payment method choice in takeovers. 相似文献

Acquisition announcements influence the stock price of target firms, providing an opportunity for insiders to obtain significant abnormal returns. We study the presence of positive abnormal returns before the announcement date, in target firms, quoted in Euronext markets (Belgium, France, The Netherlands and Portugal) from 2001 to 2007. We investigate whether the pre-announcement run-up of prices can be explained by rumours in the media and the percentage of capital previously owned by the bidding firm, among other factors. We examine cumulative abnormal returns in an event window of 60 days prior the acquisition announcement, with the event date adjusted for the previous disclosure of news about the acquisition, in the media. We compute a run-up index, and find that there are abnormal positive returns before the announcement date, confirming previous studies. We find that a significant part of the run-up is explained by: (i) market anticipation triggered by legitimate sources of information, namely, rumours in the media about the possibility of an acquisition bid and (ii) the percentage of capital previously owned in the target firm, by the bidding firm. 相似文献

This paper deals with heterogeneity and nonlinearities in the growth process by developing a two-stage strategy to identify and estimate a club convergence model with threshold externalities. Because of identification and collinearity problems, we develop an entropy-based estimation procedure which simultaneously takes account of ill-posed and ill-conditioned inference problems. First, clubs are identified by introducing a mapping structure in a conditional convergence model. Finally, we estimate a multiple club convergence model, where clubs correspond to subsets of total observations. Our procedure is applied to assess the existence of club convergence for a large sample of countries (1965–2008). 相似文献

ABSTRACT This article analyzes what influences a firm's choice of strategy—why some firms stick to defensive strategies while others rely on offensive ones. With this in mind a survey was conducted on mineral sector companies associated with the Brazilian Mining Institute. The results show that the majority of companies use an offensive strategy and that some companies use more than one strategy at the same time. That is, they possess a corporate strategy and a sustainability strategy. 相似文献
