The effect of the single currency on the Purchasing Power Parity (PPP) hypothesis is examined in this study for the 15 EU countries, vis a vis the US dollar, before and after the advent of the euro. Standard as well as nonlinear unit root tests are employed on the time series dimension. Unit root tests reject PPP and the highest half-lives are observed after the introduction of the single currency. Panel unit root (Pesaran, 2007) and stationarity tests (Hadri and Kurozumi, 2008) that take into account cross-sectional dependence are also estimated. The results remain inconclusive as panel stationarity tests fail to support PPP whereas panel unit root tests fail to reject PPP for the whole sample and for the period before the introduction of the single currency. 相似文献

We consider carefully the evidence from traded prices (as proxied by unit values) concerning the transmission of the effects of globalisation to domestic labour markets. Using standard index number techniques we decompose changes in sectoral import and export unit values into movements due to changes in pure prices of the initial bundle of goods imported or exported and changes due to upgrading of that bundle. Looking at the imports of selected European countries of textiles, clothing and footwear relative to engineering products we find evidence of strongly falling pure prices of the unskilled intensive products relative to the skilled products in the 1980s. This reinforces the view that import prices can capture the impact of globalisation in terms of falling relative prices for products produced with the intensive use of unskilled labour. However, the trends are not common across all the unskilled sectors; footwear is clearly an exception. In the absence of detailed domestic data, we look for reactions by domestic firms to increased import competition in movements in the price and composition of exports. We find evidence of stiff price competition from imports being associated with similar movements in export prices and no support for the view that import competition from low–wage countries has led to upgrading of the quality of exports. 相似文献

This article investigates the employment impact of innovation in services, using the data gathered through the 1993-95 Italian innovation survey. The empirical evidence shows that the impact of innovation on employment varies greatly across industries and according to the level of qualification of the labour force. Among small firms and in less than a half of the service sectors considered, the employment impact of innovation is positive, particularly in industries that have a strong scientific and technological base. A negative impact of innovation on employment is, on the contrary, found among large firms, capital-intensive industries and in all financial-related sectors (banking, insurance and other financial services). In these industries the labour-saving effect of innovation seems to be linked to the widespread use of Information and Communication Technologies (ICTs) which displace the least qualified employees. In the case of Italy, an overall negative impact of innovation on employment is found. It is argued that this result is affected by the Italian economy's specialisation in the most traditional service industries. 相似文献

In this article, using the data of 2008, we try to describe the impact of scale and product differentiation in 282 European
banks. While evidence of the economies of scale is less clear, the results obtained using a translogarithmic function system
show that significant economies of scope do exist even for new banking products like derivatives.

Intermodal transport has been recognized as a priority by the European Union, that has defined different budget allocations of investments to improve the shifting from road to intermodal transport, which is more sustainable. In this context, the main aim of the paper is to discuss the macroeconomic effects, in terms of economic growth, welfare and trade, of these public investments for combined transport, which aspects have been neglected in literature. A multi-country computable general equilibrium model has been used. The main results have been that the European Union benefits from these investments, but at international level, USA and Japan would lose in terms of welfare. Furthermore, the welfare change has been decomposed in its components and the results show that the trade effects are higher than the allocative effects. The robustness of the results has been tested over time and by a sensitivity analysis of the exchange rate. 相似文献

We examine the role of school grades as a signal of worker productivity under different examination systems in relation to errors that may affect student performance. Firms use school grades as a signal of workers’ effective skills, taking into account that these evaluations are effected by stochastic shocks. We show that more precise evaluation systems, being associated with a higher reactivity of wages to school grades, induce students to provide more effort. Low ability students tend to react less than high ability students. Moreover, individuals with low abilities may prefer less accurate evaluation systems. Nevertheless, when productivity increases, these systems become less convenient and the number of individuals preferring them diminishes. Our analysis highlights an important trade-off between centralised and decentralised evaluation systems. On the one hand, frequent evaluations, typical of decentralised systems, weaken the impact on grades of those errors which influence student performance and, so, reduce signal noise, while, on the other hand, different teachers generally adopt different performance assessment standards, leading to noisier evaluations. 相似文献

The transition process in Central and Eastern Europe was associated with growing environmental awareness. This paper analyses the determinants of pollution abatement and control expenditure at plant level in the case of Romania using survey data and a multilevel regression model. Our findings suggest that, although Romania has improved its environmental performance, formal and informal regulations are still only partially developed owing to the difficulties of economic transition, and heterogeneity across regions remains considerable. 相似文献
