This paper describes the degree of trade integration inside the European Union (EU) after the fifth enlargement in 2004. To achieve this goal, we build a database of information on trade flows between the new EU countries (EU‐10) and 180 commercial partners in six different sectors from 1999 to 2011. Using the standard gravity model and estimating a difference‐in‐differences specification, we analyze how joining the EU affected the intensity and direction of the EU‐10's trade flows. Our results show that though trade exchanges between the EU‐10 and EU‐15 intensified after 2004, the impact of integration was much more significant to the EU‐10 group.  相似文献

Liberal structural reforms associated to changes in the export product composition may affect economic growth, and at the same time, may yield biases in the official standard trade index numbers from developing countries and error measures in the real rate of economic and exports growth. This paper proposes a set of index numbers which incorporates the export product composition in a standard export index in such a way that changes in the current export value can be decomposed into: price changes; quantity changes, and product composition changes. In the applications of those indexes for the Peruvian case, it is found that the estimated overvaluations in the official annual average rate of growth of the real exports value and the GDP, were, respectively 3% and 0.6%, for the period 1993–2004.  相似文献

Entrepreneurs make countless pitches and presentations to prospective stakeholders that are critical to securing needed resources. Our study examines whether or not certain aspects of visual presentations are more likely to elicit stakeholder interest. By applying precepts of information visualization theory, we empirically examine 42 early‐stage venture poster presentations to determine the impact design and content have on attracting stakeholder interest. Our findings suggest that visualization matters; posters that included specific visual devices garnered a higher level of interest among prospective stakeholders, including investors and collaborators.  相似文献

The colonization of Mallorca gave rise to a late‐feudal agrarian society that evolved towards capitalism based on large estates owned by noblemen who hired large numbers of wage labourers from among smallholders living in agro‐towns, the dispossessed remnants of a formerly wealthier peasantry. These well‐off peasants originated from when the colonization frontier was open in the 13th and 14th centuries, but had been defeated when three peasant–plebeian revolts were crushed. Afterwards, Mallorca followed a latifundist transition towards agrarian capitalism similar to southern Italy or Spain, in sharp contrast with the middle‐peasant paths seen in Catalonia or Valencia. The land rent rose, while agricultural wages fell from 1659 to 1800. Peasant families could not survive, and had to supplement wages with the products of their own plots. This set a socio‐agroecological limit to growth in this agrarian class structure. The agrarian crisis at the end of the 19th century bankrupted the Mallorcan nobility. Bankers bought much of the land and sold it on as small allotments. This expanded the intensive cropping formerly limited to agro‐town belts, giving rise to a new “peasantization”. Despite their subordination, Mallorcan peasants had survived and created complex agroecological landscapes endowed with a rich biocultural heritage.  相似文献

Given that the use of Likert scales is increasingly common in the field of social research it is necessary to determine which methodology is the most suitable for analysing the data obtained; although, given the categorization of these scales, the results should be treated as ordinal data it is often the case that they are analysed using techniques designed for cardinal measures. One of the most widely used techniques for studying the construct validity of data is factor analysis, whether exploratory or confirmatory, and this method uses correlation matrices (generally Pearson) to obtain factor solutions. In this context, and by means of simulation studies, we aim to illustrate the advantages of using polychoric rather than Pearson correlations, taking into account that the latter require quantitative variables measured in intervals, and that the relationship between these variables has to be monotonic. The results show that the solutions obtained using polychoric correlations provide a more accurate reproduction of the measurement model used to generate the data.  相似文献

This paper explores how large‐scale social‐driven collaborations might grow in scale and help promote political change. We present the results of a qualitative investigation of a complex platform where multiple and hybrid collaborations co‐exist and where civil society plays a central role. Based on a longitudinal comparative case study, we draw a processual model describing micro‐practices and pathways of engagement. We show that the emergence of these collaborations requires a new type of convener, one that is able to manage the interplay between the sharing/co‐creation of abundant resources and the coordinated decentralization of informal authority. Our study extends existing debates on the role of resources and authority, showing the complementarity between possession and practice perspectives of power. Finally, we identified synergies between collaboration and social movement literatures, particularly showing that large‐scale collaborations could be mobilized to refine social movement agendas and achieve more purposive collective action.  相似文献

Generalizability theory is used to assess the validity of the conceptualisation and implementation design of an evaluation programme carried out in the context of five care centres for homeless children. In order to measure the implementation process of the social intervention programme at three different observation moments, a rating scale questionnaire was developed. Crossed, three-facet random-effects designs (items × subjects × observation moments) for each care centre were analysed to develop different generalizability and decision studies and thus optimise the overall evaluation design. Given the generalizability analyses performed, the way in which generalizability results are complemented by log-linear analyses is discussed in relation to the evaluative objectives.  相似文献

Based upon an adjusted Crepon–Duguet–Mairesse (CDM) model, this paper analyzes the relationship between investment intensity, public financial support, innovation, and total factor productivity (TFP) for a sample of manufacturing firms of Peru with data obtained from the 2004 survey of science, technology, and innovation (STI) activities. The estimation of the model indicates that large firms are more likely to invest in STI activities and firms' size increases the probability of producing technological inovation (TI) and non‐technological innovation (NTI). STI firms' investment intensity and public financial support have also helped manufacturing firms to increase the probability of producing TI outcomes. Further, such support may have increased firms' investment on STI activities. The innovation effects on TFP, however, were statistically not clear or robust. Thus, whereas investment intensity did increase firms' TPF in low‐tech manufacturing firms, this is not the case for high‐tech firms. For this group of firms, relatively high capital–labor ratio and the availability of a high level of human capital seem to promote higher levels of TFP.  相似文献

This paper uses detailed micro data on services exports at the firm–destination–service level to analyse the role of firm heterogeneity in shaping aggregate services exports in Belgium, France, Germany and Spain from 2003 to 2007. We decompose the level and the growth of aggregate services exports into different trade margins paying special attention to firm heterogeneity within countries. We find that the weak export growth of France is at least partly due to poor performance by small exporters. By contrast, small exporters are the most dynamic contributors to the aggregate exports of Belgium, Germany and Spain. Our results highlight the importance of firm heterogeneity in understanding aggregate export growth.  相似文献

This paper analyses the impact in Catalonia of the grape Phylloxera plague in Europe (1865–90). A statistical model is used to analyse the economic resilience of 35 districts in Catalonia to this external ecological and economic shock, and to explain why districts in the provinces of Barcelona and Tarragona resumed growing wine grapes after the plague, in contrast to districts in Girona and Lleida provinces. The opportunity cost of labour, the demand pull of Barcelona's commercial growth, and the agro-climatic suitability of land for growing grapes are used to explain the differing capacities of districts to endure the Phylloxera plague in Catalonia.  相似文献
