This paper uses firm-level data recorded in the Amadeus database to investigate the distribution of labour productivity in different European countries. We find that the upper tail
of the empirical productivity distributions follows a decaying power-law, whose exponent α is obtained by a semi-parametric estimation technique recently developed by Clementi et al. [Physica A 370(1):49–53, 2006].
The emergence of “fat tails” in productivity distribution has already been detected in Di Matteo et al. [Eur Phys J B 47(3):459–466,
2005] and explained by means of a model of social network. Here we show that this model is tested on a broader sample of countries
having different patterns of social network structure. These different social attitudes, measured using a social capital indicator,
reflect in the power-law exponent estimates, verifying in this way the existence of linkages among firms’ productivity performance
and social network. 相似文献

There has been limited coverage of the corporate responsibility (CR) practices of small and medium-sized enterprises (SMEs) in the mainstream CR literature. Furthermore, there has been no systematic analysis of the responsibilities of the high value jewellery industry and jewellery SMEs in particular. This study explores the potential for harm and value creation by individual stakeholders in fine jewellery production. Using the harm chain and institutional theory to frame our investigation, we seek to understand how small businesses within the fine jewellery industry respond to the economic, social and environmental challenges associated with responsible jewellery production, and to investigate how they perceive and negotiate the tensions between responsibility and the resistance derived from the operational norms of secrecy and autonomy within the industry. Our exploratory research provides illustrative examples of how complex harm networks operate within and across the fine jewellery industry, and demonstrates the inter-relationships that exist across the different stages of the fine jewellery harm chain. Findings suggest that institutional forces are coalescing towards a more responsible agenda for the fine jewellery industry. Moreover, while CR is a tool to disrupt harmful institutional norms and practices within such an industry, it requires the co-creation of new transformative business models and multi-stakeholder involvement including firms (SMEs and MNEs), trade associations, non-governmental organisations and consumers. Solutions include national and international legislation, price adjusted certification routes for small firms, harmonisation of industry CR standards to reduce overlap in certification and regulation and gem and precious metal “track and trace” schemes. 相似文献

We investigate the possible existence of asymmetries among Euro Area countries reactions to the European Central Bank monetary policy. Our analysis is based on a Structural Dynamic Factor model estimated on a large panel of Euro Area quarterly variables. Although the introduction of the euro has changed the monetary transmission mechanism in the individual countries towards a more homogeneous response, we find that differences still remain between North and South Europe in terms of prices and unemployment. These results are the consequence of country‐specific structures, rather than of European Central Bank policies. 相似文献

This note estimates the causal effect of life expectancy on per capita income and tests the hypothesis of a non-monotonic effect using finite mixture models. The results confirm the hypothesis and qualify recent evidence for a negative effect by Acemoglu and Johnson (2007). 相似文献

This paper analyses the interdependencies existing in wholesale electricity prices in six major European countries. The results of a robust multivariate long‐run dynamic analysis reveal the presence of four highly integrated central European markets (France, Germany, the Netherlands and Austria). The trend shared by these four electricity markets appears to be common also to gas prices, but not to oil prices. The existence of a common long‐term dynamics among electricity prices and between electricity prices and gas prices can be explained by the similarity of the market design across Europe and by the same marginal generation technology. Since standard unit root and cointegration tests are not robust to the peculiar characteristics of electricity prices time series, we also develop a battery of robust inference procedures that should assure the reliability of our results.

This paper explores the statistical properties of household consumption-expenditure budget share distributions – defined as the share of household total expenditure spent for purchasing a specific category of commodities – for a large sample of Italian households in the period 1989–2004. We find that household budget share distributions are fairly stable over time for each specific category, but profoundly heterogeneous across commodity categories. We then derive a parametric density that is able to satisfactorily characterize (from a univariate perspective) household budget share distributions and: (i) is consistent with the observed statistical properties of the underlying levels of household consumption-expenditure distributions; (ii) can accommodate the observed across-category heterogeneity in household budget-share distributions. Finally, we taxonomize commodity categories according to the estimated parameters of the proposed density. We show that the resulting classification is consistent with the traditional economic scheme that labels commodities as necessary, luxury or inferior. 相似文献

We provide new evidence that differences in international tax rates and tax regimes affect multinational firms' debt location decisions. Our sample contains 8287 debt issues from 2437 firms headquartered in 23 different countries with debt-issuing subsidiaries in 59 countries. We analyze firms' marginal decisions of where to issue debt to investigate the influence of a comprehensive set of tax-related effects, including differences in personal and corporate tax rates, tax credit and exemption systems, and bi-lateral cross-country withholding taxes on interest and dividend payments. Our results show that differences in personal and corporate tax rates, the presence of dividend imputation or relief tax systems, the tax treatment of repatriated profits, and inter-country withholding taxes on dividends and interest significantly influence the decision of where to locate debt and the proportion of debt located abroad. Our results are robust to firm and issue specific factors and to the effect of legal regimes, debt market development, and exchange rate risk. 相似文献

The general concern on the environmental implications of the rising demand for coal registered in China during the last few years has induced considerable research effort to produce accurate forecasts of China's energy requirements. Nevertheless, no previous study has modelled the coal demand in China at provincial level. The aim of this paper is twofold. First, we estimate and forecast the Chinese demand for coal using panel data disaggregated by provinces and accounting for spatial heterogeneity. Second, given the spatial nature of the data, we explicitly capture the spatial autocorrelation among provinces using spatial econometrics. In particular, we specify the Chinese industrial coal demand at provincial level with fixed-effect spatial models. The empirical results show that the fixed-effect spatial ADL model is able to capture the existing interdependence between provinces. This model forecasts an average annual increase in coal demand to 2010 of nearly 2%. 相似文献

An increasing number of countries are orientating their development strategies based on the millennium development goals (MDG), a broad set of directives agreed to by the United Nations (UN) in the year 2000. Developing coherent plans to achieve MDG has been complicated by their multidisciplinary nature, and by the complexity of the system being managed. The “system” here is the socio-economic construct within which populations live and operate. In an effort to support this planning process, various approaches have been developed to help realize MDG within specified budgets. The work described here complements the most commonly used approaches by analyzing the impact of alternative interventions in an integrated socio-economic-environmental framework. In doing so, we utilize system dynamics, which is well-suited to support the analysis of dynamic, complex issues such as those that characterize MDG planning. Such an approach allows us to estimate impacts of MDG-related interventions on the economic and demographic development of countries under study, as well as the possible synergies between and amongst selected interventions, e.g., those involving education and health. Results indicate that failure to account for such factors can lead to sub-optimal strategies. Our objective is thus to provide policy-makers with a more comprehensive view of the outcomes generated by alternative MDG interventions, with emphasis on the ability to finance given strategies. 相似文献
