We generalize and extend the sequential model proposed by the resources and appropriation theory to explain the digital divide in the European Union plus the United Kingdom (EU27+UK). We measure the theoretical constructs of the model with data provided by the EU and test the theoretical predictions using a partial least squares structural equation model. We find support for the hypothesized relationships but find that the effects vary depending on the digital development level of countries. While education overall is the primary determinant of the social production of digital inequalities, a country's digital development level is crucial for less well-educated Europeans. These findings have theoretical and practical implications: (1) they call into question the homogeneity of the effect of causal relationships and the assumption that individuals differ only in terms of motivation, access, and digital skills, and (2) they indicate that socially disadvantaged Europeans benefit from living in more digitally developed countries. 相似文献

Connunication of a hepatic hydatid cyst to the duodenum appears to be extremely rare. This is the first case described in the imaging literature of hepatic echinococcosis fistulized to the duodenum studied by computed tomography. 相似文献

ABSTRACTWe explore in this note different structural models of the impact of process and product innovation on firms' demand and production cost functions. We find that the introduction of process and product innovations affects them differently as could be expected. Both product and process innovation shift forward the demand for the products of the firm. Process innovation reduces production marginal cost, but not always. A possibility, that we cannot prove or reject with the current specification of our models and available data, is that process innovation associated with product innovation raise marginal cost. Interestingly, we also find that advertising significantly augments demand but does not affect production marginal cost. To obtain broader conclusions, richer data will be needed allowing an enlargement of the model, in which process and product innovations could be specified distinctively and well identified. 相似文献

Previous research on the International Financial Reporting Standards (IFRS) policy choices of large listed companies found a very strong association between policy choice and country. Nationally based pre‐IFRS practices largely explain IFRS policy choices. Nevertheless, some of the policy choices appear to be influenced from abroad, perhaps chosen in order to increase comparability. It has been suggested that smaller companies might be less influenced from abroad, and therefore might display even clearer national profiles of IFRS practice. This paper examines the accounting policy choices made within IFRS financial statements by small listed companies in five major countries. We find highly significant differences between the policies of small and large companies. We also find that small companies make more homogeneous choices, within a country, than large companies do. As a result, the previously published national profiles of the IFRS practices of large companies are misleading in the context of smaller ones. 相似文献

The objective of this paper is to improve estimations of the size and scope of the underground economy by introducing a new approach that combines the advantages of the two most commonly used approaches, i.e. currency demand and multiple indicators, multiple causes (MIMIC). The new approach is applied to Germany. Among other things, it is shown that the approach yields improved estimation results. Some policy perspectives are discussed in the concluding section. 相似文献

This article presents new estimates of the Greek underground economy and explores the link between the underground economy and aggregate debt. We show that the Greek underground economy has been underestimated heavily and has been on a rising trend again since Greece adopted the Euro. We also present evidence that the size of the underground economy is positively related to the debt-to-GDP ratio, implying that fighting the underground economy is also conducive to financial and macroeconomic stability. Our results suggest that for our sample of 11 EMU member countries, the loss of the inflation tax as an economic policy instrument had drastic consequences. While the underground economy did not have a statistically significant impact on aggregate debt before the introduction of the Euro, it has pushed up the debt-to-GDP ratio in our sample since. 相似文献

This paper analyses the relationship between spatial density of economic activity and interregional differences in the productivity
of industrial labour in Spain during the period 1860–1999. In the spirit of Ciccone and Hall (Am Econ Rev 86:54–70, 1996) and Ciccone (Eur Econ Rev 46:213–227, 2002), we analyse the evolution of this relationship over the long term in Spain. Using data on the period 1860–1999 we show the
existence of an agglomeration effect linking the density of economic activity with labour productivity in the industry. This
effect was present since the beginning of the industrialisation process in the middle of the nineteenth century but has been
decreasing over time. Our results show that doubling employment density raises average labour productivity in the industrial
sector by between 3 and 5% in all periods analysed, with the exception of the last segment from the twentieth century. Hence,
we find significant evidence of agglomeration effects. However, these effects seem to have been falling sharply from the mid-nineteenth
century until late in the twentieth century, and there appears to be no positive evidence of agglomeration effects in industry
in the period 1985–1999. This result could be explained by an important increase in the congestion effects in large industrial
metropolitan areas that would have compensated the centripetal or agglomeration forces at work. Furthermore, this result is
also consistent with the evidence of a dispersion of industrial activity in Spain during the last decades.
