What is the economic impact of joining a currency union? Is this impact heterogeneous across regions? And how does it change in case of a recession? We answer these questions by investigating the economic impact of joining the euro area for the latecomers, that is, the eastern European countries that adopted the euro after 2002. Differently from previous literature, we use NUTS-2 regions as units of analysis. This novelty allows us to investigate the theoretical predictions of a currency union impact at a more appropriate geographical level. Using a recently developed counterfactual approach, we estimate the overall as well as the disaggregated impact of joining the euro area. We find that the adoption of the euro brought about a small positive effect, which was, however, dampened by the Great Recession. Individual regional estimates suggest heterogeneous returns with benefits accruing mostly to core regions.  相似文献

It is widely documented that Thailand's National Family Planning Program (NFPP) has been successful in increasing contraceptive prevalence and reducing fertility. In this paper, we investigate to what extent setting up the NFPP between the mid 1960s and the early 1990s in local communities per se has added to this success. For this, we use data from the 1992/93 Survey on the Status of Women and Fertility in Thailand (SWAFT). We find that presence of the NFPP in a community is associated with less than two percentage points higher proportion of women with contraceptive experience at ages 15–19, to about six percentage points higher proportion at ages 35–39, and with about a 3 per cent lower completed fertility. Although these associations are relatively small, they are significant and may suggest that setting up the NFPP in local communities per se has been important for a small group of hard-to-reach women with unmet contraceptive needs.  相似文献

A multidisciplinary approach combining scientific and historical data is developed in order to identify the environmental factors that cause degradation of stones and to attempt to date the onset of degradation and assess the time needed for its development. The method is applied to the Castle of Chambord, a prestigious monument in the Loire Valley in France. The genesis of the two main types of degradation (spalling and flaking) and the kinetics of their development are identified and analysed. The correlation between the different mappings and iconographic documents reveal that flaking develops on any type of fine limestone and can appear less than 60 years after the stone is placed on the castle for Richemont limestone, and less than 10 years for tuffeau. The other main type of degradation, spalling, is limited to tuffeau, but it is more difficult to quantify the kinetics of its development.  相似文献

HMS Falmouth is the only known wreck of a Town Class light cruiser, which were ‘arguably the best cruisers of the First World War’ (Lyon, 1977c: 49). This article reports on a project to better understand the significance of the wreck and to raise public awareness of the heritage of the First World War at sea. Although the wreck is heavily degraded it is still of considerable importance, raising methodological questions about the role of multibeam survey and 3D visualization, access to archival material, and the characteristics of archaeology as applied to 20th‐century warships.  相似文献

A new method for interpreting lead isotope ratios of artefacts is presented: a numerical and graphical ‘match–no match‘ with possible raw materials. By calculating the definite integral under the kernel density estimate plot of different mining districts, using open-access software and legacy data, the relative probability that an object is made of an ore is indicated. A match with the reference data set may indicate the true origin, while no match indicates an unknown origin, that is, not present in the data set of mineral resources. Likewise, the composite or recycled nature of artefacts can be investigated in a probabilistic manner.  相似文献

This research starts its journey from a video that failed to be published during the 2009 uprising in Iran. By following data outside the common trajectories of data circulation in the global North, this paper offers new geographical and data imaginations neglected by the universalised understandings of data and its political economy. Consequently, data’s behaviour as a thing is thoroughly investigated in the “follow the thing tradition” by scrutinising data as a commodity, its meanings and its associations. Using actor-network-theory, the paper highlights data’s open and contested character as well as the breakdowns throughout its journey. Following an uncirculated video via its traces sheds light on data’s agency in evoking different assemblages and spatialities. It also reflects on the epistemological importance of not treating the Southern data as exceptional and calls for a theoretical landscape that does not leave many realities of data out in its homogenised universal narrative.  相似文献

This article examines wage differences across Spain's NUTS-2 regions along the entire wage distribution based on matched employer-employee microdata from 2006 to 2014. Unlike previous related studies, we properly control for differences in regional purchasing power parities, which are very large in practice. Although part of the raw regional wage differences observed is explained by differences between regions in productive structures, and, to a much lesser extent, in labor forces, noteworthy, very similar throughout the wage distribution regional differences net of composition effects arise even after controlling for a broad set of individual and firm characteristics.  相似文献
