The aim of this work is to demonstrate how public university hospital (UH) managers can improve the process of decision-making by using the measurement of economic value added to the society (EVAS) generated by these organizations. Thus, the economic values of the organization and its departments were calculated, according to the theory studied: measurement model of economic result of Slomski (1996). It was considered the conduction of a case study in a public UH, evaluating its economic performance in a 3-year period. For the interpretation of results, the Data Envelopment Analysis (DEA) which categorized the departments of the hospital studied as efficient or inefficient was used. This study revealed that managers can improve the decision-making process by using the EVAS, since it has been established that this measurement of economic value has sensitivity to identify which of the economic value drivers should be emphasized in the management. 相似文献

This paper uses the gravity model of trade to investigate the effect of foreign aid on exports of aid recipients to donor countries. Most of the theoretical work emphasises the possible negative impact of aid on recipient countries’ exports, primarily due to exchange rate appreciation, disregarding possible positive effects of aid in overcoming supply bottlenecks and promoting bilateral trade relations. Using non-stationary panel (cointegration) estimators to control for omitted variable and endogeneity bias, we find that the net effect of aid on recipient countries’ exports is insignificant, both for our sample (of 123 countries) as a whole and for important regional sub-samples. This finding is in line with the small or insignificant macroeconomic impact of aid found in earlier studies and also suggests that exporters in recipient countries are not benefiting from improved trade relations with donors. 相似文献

The contribution of this paper consists in applying several techniques to estimate a composite indicator of sustainable urban mobility for 116 Italian provincial towns, as proposed by Luzzati and Gucciardi (2015). The aim is to provide the decision-maker with a richer set of information on sustainable mobility, making explicit the impact of the techniques used on the values obtained. A set of 16 indicators with a nested structure has been selected and 33 combinations of normalization, weighting, and aggregation techniques are applied. The results are presented by city, by city groupings (size and location), and focusing on the ten largest Italian cities. It is found that small cities perform better in terms of sustainable mobility than medium or large cities. As expected, in some cases (e.g., Milan) the intervals of the results obtained are quite large, indicating that the techniques used to normalize, weight, and aggregate the indicators highly affect the performance indexes. In other cases (e.g., Rome) the results are stable across methodologies. 相似文献

This paper adopts fixed‐effect panel methodologies to obtain TFP values for a sample of 76 countries from 1960 through 2003. Our results are robust to the use of different estimators (LSDV, Kiviet‐corrected LSDV, and GMM). They show that TFP dynamics are characterized by a process of conditional convergence where most countries do not catch up with the U.S., and where human capital plays an important role in technology adoption, as suggested by Nelson and Phelps in 1966. Such a role is robust to the inclusion of controls for the quality of institutions in a country. Further, our results imply a plausible link between stages of development and returns to different levels of education. Finally, we calculate the minimum human capital level necessary to generate catch‐up and find that virtually all countries are above that level—a result that again emphasizes the importance of human capital in technology diffusion. 相似文献

This paper investigates the time series of realized correlations between global industries and the world market over the 1979–2008 period. The behavior of industry correlations is characterized by long-term swings, with a period of historically low correlations in the late 1990s. The Telecommunications and the Financials industries show a positive secular trend. Global industry correlations move countercyclically. Furthermore, there is evidence that industry correlations are higher for market downside moves than for upside moves. 相似文献

Although new paint products and technologies have been developed, the sector of paint application still contributes substantially to total volatile organic compound (VOC) emissions. Recent environmental legislation, especially the EU Solvent Emission Directive 1999/13/EC and its transposition into national law, coming into force in 2007, will have an important influence on the sector structure and the associated supply chain, especially for small- and medium-sized enterprises (SMEs). This paper summarises a comprehensive scenario analysis to explore possible future trajectories for the sector. The main focus is on paint application activities, considering in particular the consequences of new environmentally friendly products and technologies which can be used by SMEs. Four different scenarios representing possible future states of the sector are evaluated, taking into account environmental, technical and socio-economic aspects along the associated supply chain and life cycle. The scenarios allow the formulation of recommendations and guidelines for policy makers and industries. This example confirms that interdisciplinary scenario analysis is a suitable approach to investigate possible future development of an industrial sector. 相似文献

Reductions in firing costs are often advocated as a way of increasing the dynamism of labour markets in both developed and less developed countries. Evidence from Europe and the U.S. on the impact of firing costs has, however, been mixed. Moreover, legislative changes both in Europe and the U.S. have been limited. This paper, instead, examines the impact of the Colombian Labour Market Reform of 1990, which substantially reduced dismissal costs. I estimate the incidence of a reduction in firing costs on worker turnover by exploiting the temporal change in the Colombian labour legislation as well as the variability in coverage between formal and informal sector workers. Using a grouping estimator to control for common aggregate shocks and selection, I find that the exit hazard rates into and out of unemployment increased after the reform by over 1\% for formal workers (covered by the legislation) relative to informal workers (uncovered). The increase of the hazards implies a net decrease in unemployment of a third of a percentage point, which accounts for about one quarter of the fall in unemployment during the period of study. 相似文献

This paper uses the Italian Social Security employer-employee panel to study the effects of the Italian reform of 1990 on worker and job flows. We exploit the fact that this reform increased unjust dismissal costs for businesses below 15 employees, while leaving dismissal costs unchanged for bigger businesses, to set up a natural experiment research design. We find that the increase in dismissal costs decreased accessions and separations for workers in small relative to large firms, especially in sectors with higher employment volatility, with a negligible impact on net employment. We also find some evidence suggesting that the reform reduced firms' entry rates and employment adjustments, but had no effect on exit rates. 相似文献

The evidence here indicates that sovereign debt rating and credit outlook changes of one country have an asymmetric and economically significant effect on the stock market returns of other countries over 1989–2003. There is a negative reaction of 51 basis points (two-day return spread vis-á-vis the US) to a credit ratings downgrade of one notch in a common information spillover around the world. Upgrades, however, have no significant impact on return spreads of countries abroad. Closeness (e.g., geographic proximity) and emerging market status amplify the effect of a spillover. Downgrade spillover effects at the industry level are more pronounced in traded goods and small industries. 相似文献

This study seeks to identify the causal effects of foreign ownership on productivity, the demand for skilled labour and wage inequality. With this aim, we use differences‐in‐differences techniques for a panel of Uruguayan manufacturing firms in the period 1997–2005. Our results seem to indicate that FDI causes higher productivity and increased demand for skilled labour. Furthermore, although average wages are higher in foreign‐owned firms than in domestic ones, the wage gap between skilled and unskilled workers is wider. It follows that promoting foreign investment enhances productivity. In addition, due to the greater demand for skilled workers, policies such as training schemes would be conducive to raising productivity still further, while other social policies could help to mitigate the wage inequality effects. 相似文献
