This paper analyses public e-procurement implementation and emphasizes its main difficulties and impacts in relation to the type of public organizations. The primary impacts and changes in the Portuguese public sector are analyzed within the new legal framework, which adopts mandatory e-procurement for any open, restricted or negotiated procedure. In this sense, two surveys carried out in consecutive years were conducted to assess the implementation difficulties and impact of e-procurement in the Portuguese public sector.The major value of this research is that it presents and discusses, for the first time, evidences about difficulties and impacts on the mandatory adoption of public e-procurement, based on the case of Portugal. The results show that the entities’ administrative level influences the e-procurement implementation, which is influenced by the innovation adoption process. 相似文献

We examine how exchange rate regimes affect fiscal discipline by investigating European countries as they transitioned from flexible to fully fixed exchange rates under the Euro. We apply the synthetic control method to estimate, for each Eurozone country, its counterfactual budget stance under flexible rates. Our evidence strongly suggests that fixing exchange rates negatively impacted negatively fiscal discipline. However, effects were not homogeneous, as they were mediated by political factors. For example, countries where policymakers faced a longer political horizon and operated within a more cohesive political environment, managed to perform better in terms of fiscal discipline. 相似文献

From 1980 to 1990 Portugal experienced a generalized liberalization of economic activity, due in large part to its 1986 integration in the European Union. This paper studies the changes in the Portuguese distribution of household income and expenditure during this period, using micro-data on household budgets and applying recent developments in statistical inference for Lorenz curves. We find a significant increase in six measures of welfare and an unambiguous decrease in the inequality of the respective distributions. Different explanations for the findings of decreased inequality are discussed. 相似文献

Planning as part of public sector decision-making situations is an activity of critical importance, with direct relevance for urban planners. The ramifications of such decisions generally have significant effect on peoples’ lives. The current paper deals with the comparison between territorial maps in the context of districting problems with a strong socio-economic component. The theoretical problem involves the comparison of two partitions in a connected, undirected, and planar graph. In considering this problem, we introduce three new indices to compare territory partitions: compatibility, inclusion, and distance, all of which have importance for real-world planning situations. Numerical experiments of these indices were carried out for the communes network in (Iˆle de France), France. 相似文献

Abstract:In this article, we study the enrollment decision of candidates to Portuguese public Higher Education Institutions (HEIs). We classify candidates according to their revealed preference for regional mobility and measure the impact of their mobility status on the likelihood of enrollment. For instance, candidates succeeding to be placed in their home district are about fourteen percentage points more likely to enroll than those pushed away. We also show that distance deters enrollments, even for candidates that reveal a preference for migrating. Finally, we measure the impact of the availability of private sector alternatives in the home district on the likelihood of enrollment and show that their existence reduces the likelihood of enrollment by up to nine percentage points. 相似文献

Endogenous growth theory suggests scale and trade as the determinants of total factor productivity (TFP) growth. The literature on social capital suggests that the levels of trust and participation in societies may affect cooperation and innovation. While there is evidence of the role of trade and inconclusive evidence on the role of social capital, previous studies have generally omitted two factors, out of the three mentioned, used small sample sizes and emphasized economic growth rather than technological progress. Our study addresses these shortcomings. We find robust evidence of the role of trade in fostering technological progress which is invariant to TFP proxies and independent of the debate on measuring TFP. Moreover, there is no clear role for scale, and a country rate of TFP growth seems to increase the most the more the country trades with dynamic economies that are different from. We uncover a positive effect of social capital, which is more significant in richer countries, suggesting that other characteristics, such as institutional quality, may be complementary to social capital. The paper's results are robust to different specification and estimation methods. 相似文献

This paper proposes a discussion on evolutionary technological change and economic growth theory, using the Lakatosian Methodology of Scientific Research Programmes as an appraisal criterion. Since the persistence of some inflexibility in this approach made it difficult to capture fundamental features of the scientific undertaking at hand, an alternative hypothesis was explored, that developed by Hoover (Scientific research program or tribe? A joint appraisal of Lakatos and the new classical macroeconomics. In: de Marchi N, Blaug M (eds) Appraising economic theories: studies in the methodology of research programmes. Edward Elgar, Aldershot, 1991). This latter framework is used here not as a formal methodology but rather as a language to find patterns in these theories. This exercise evolved then towards a number of considerations on the confrontation between these evolutionary theories particularly in terms of that which can be seen (in a loose sense) as their “rival research programme”, the new neoclassical growth models. 相似文献

We look at the effect of exchange rate regimes on fiscal discipline, taking into account the effect of underlying political conditions. We present a model where strong politics (defined as policymakers facing longer political horizon and higher cohesion) are associated with better fiscal performance, but fixed exchange rates may revert this result and lead to less fiscal discipline. We confirm these hypotheses through regression analysis performed on a panel sample covering 79 countries from 1975 to 2012. Our empirical results also show that the positive effect of strong politics on fiscal discipline is not enough to counter the negative impact of being at/moving to fixed exchange rates. Our results are robust to a number of sensitivity checks, including the use of different estimators, alternative proxies for fiscal discipline and sub-sample analysis. 相似文献

Stereotypes of individuals in relation to countries may affect their attitudes toward products from these nations (the country of origin effect). The objective is to analyze the country of origin effect for Brazilian beef in Europe, considering the role of moderators such as gender, age, and product involvement. It was concluded that beliefs in relation to countries and their impact on attitudes toward products from these countries may differ according to demographic issues. We also conclude that aspects related to communication, distribution, and differentiation of Brazilian products have received the worst evaluation by consumers who participated in the survey. 相似文献
