This paper examines jobs in the information society and the new economy, taking as its focus the call center industry. More
specifically, the study analyzes the degree of variability of the quality of call center jobs. In order to achieve this objective,
an index of job quality is generated, and an empirical analysis of the characteristics of jobs in call centers is carried
out. This allows us to determine the level and variability of quality of jobs in this sector and to establish whether the
reality of these jobs is as good as the forecasts for work in the new economy.

The aim of this paper is to explore the relationship between income inequality and health in the European Union countries using new data from the European Community Household Panel (ECHP). The heterogeneity of the households has been approached using different equivalence scales. A variety of different model specifications were tried using different dependent variables such as life expectancy at birth and child mortality. The results give support to the influence of income inequality on health indicators using aggregate data and panel techniques, and show the sensitivity of the Gini index to the equivalence scale considered. 相似文献

We analyze the impact of a drop in fertility on the optimal allocation of resources in an overlapping generations economy where old workers care about leisure. We also characterize optimal dynamics and study the decentralization of the optimum by means of inter‐generational transfers and/or public debt. We conclude that the policy recommendations of postponing retirement is fragile and depend on preferences and technologies. Also, even when the optimal adjustment of public debt goes into the expected direction in the long run—i.e., public debt should decrease—this may not be the case during the transition. 相似文献

We study the links between fiscal stimulus packages during times of crisis and households' liabilities. We do so by using household-level data on income and liabilities from the Consumer Expenditure Survey, and estimating an empirical model along those in the literature on the consumption effects of these packages. We find that receiving a check from the government tends to translate into a reduction in outstanding liabilities for American households. This effect is robust to controlling for income levels and household size. The effects are driven by households whose income is below the median and by those who remain employed during the crisis. 相似文献

The analysis of poverty measures has been receiving increased attention in recent years. This paper contributes to the literature by developing percentile ratio estimators based on the pseudo empirical likelihood method. In practice, variances of poverty measures could be not expressible by simple formulae and consequently other techniques should be used in the variance estimation stage. Assuming percentile ratios, resampling techniques are investigated in this paper. A numerical example based on data from the Spanish Household Panel Survey is taken up to illustrate how suggested procedures can perform better than existing ones. The effect of a model-misspecification on the proposed estimators is also evaluated by using simulated populations. 相似文献

The crisis of the new economy might have cast doubt on the usefulness of the Internet for business activities. However, it
is unquestionable that the possibilities offered by Internet-based technologies in terms of information processing, transfer
and collection enable the firm to improve market knowledge and the relationship with clients and suppliers.
This work explores, theoretically and empirically, the possibilities offered by the Internet to facilitate the internationalization
process of Small and Medium Enterprises (SMEs) as well as to improve the relationship with other firms within the same value
chain. Using a wide representative sample of Spanish SMEs, the empirical analysis confirms the benefits of the Internet in
both cases. 相似文献

The statistical power and Type I error rate of several homogeneity tests, usually applied in meta-analysis, are compared using Monte Carlo simulation: (1) The chi-square test applied to standardized mean differences, correlation coefficients, and Fisher's r-to-Z transformations, and (2) S&H-75 (and 90 percent) procedure applied to standardized mean differences and correlation coefficients. Chi-square tests adjusted correctly Type I error rates to the nominal significance level while the S&H procedures showed higher rates; consequently, the S&H procedures presented greater statistical power. In all conditions, the statistical power was very low, particularly when the sample had few studies, small sample sizes, and presented short differences between the parametric effect sizes. Finally, the criteria for selecting homogeneity tests are discussed. 相似文献

Science policy is being challenged. Conceptions of innovation and the nature of research are rapidly being forced beyond traditional views which see innovation as a linear process and science policy in terms of funding issues. Indeed, the policy challenge is being defined by the tension between trying to conduct or encourage research that is at or near an expanding research frontier, while simultaneously functioning within 'steady state' fiscal environments. One key manifestation of this challenge—which is underpinned by a new social contract between the scientific and government communities—is being expressed in terms of the changing role that research instrumentation is playing with regard to research management, research policy and research planning. This paper examines several Candian example f the changing nature of research, with particular reference to the role of instrumentation; it also outlines the particular challenges that small open econmies must face with respect to instrument-intensive research and offers a possible taxonomy for analyzing innovation and policy options. 相似文献
