Cet article examine les différentes politiques économiques susceptibles d'avoir des répercussions sur l'économie sociale en tant que secteur institutionnel.En premier lieu il présente un cadre d'analyse permettant d'appréhender les contenus des politiques et en offre trois typologies.A la lumière de ce cadre dans unpremier temps il fait unbilan global des politiques mises en oeuvre en Europe pour se centrer dans un deuxième temps sur l'Espagne l'un des pays de l'Union où le niveau de développement de ces politiques est le plus avancé .Pour terminer, l'auteur évalue l'efficacité des principales mesures de politique économique mises en oeuvre dans ce pays.
The article considers different economic policies likely to affect the social economy sector as an institutional sector. In a first time it sets up an analytical framework which allows to apprehend the policies contents and offers three typologies. In the light of this framework it first makes a global evaluation of policies implemented in Europe and then focuses on Spain, one of the Union countries with the highest level of development of these policies. Finally, the author evaluates the efficiency of the main measures of economic policy applied in this country. 相似文献

Motivated by the empirical evidence on endogenous labor effort and wage differentials, this paper explores implications for distribution and growth of firms using different strategies to elicit effort from workers. The frequency distribution of effort‐elicitation strategies across firms is governed by a replicator dynamic that generates wage differential as a long‐run equilibrium. Although firms willing to elicit more effort have to compensate workers with a higher wage rate, a larger proportion of firms adopting such strategy will not necessarily produce a higher wage share and thereby a higher growth rate. The intuition is that, depending on the accompanying rise in labor productivity, the wage share may not vary positively with the proportion of firms paying higher wages. 相似文献

This study presents a characterisation of online reviews for small and medium hotels (SMH) in Portugal. We collected and analysed 1500 online reviews from 50 SMH. The findings show that room, staff and location were the concepts most frequently appeared in the reviews, with cleanliness, friendliness, helpfulness, and centrality of position the terms most frequently used to qualify the concepts. This study points out the main features which SMH managers should prioritize. 相似文献

The article considers the social services supply in the Spanish area of Valencia. The objective is double. First the authors analyse what describes the partnership between public sector and NPO in this area, by using a systemic conception of the social services sector where three main functions can be identified (financing, production and distribution, and regulation). Secondly they search for theoretical arguments explaining this partnership principle. This second section is mainly based on the NPO approach. 相似文献

This study introduces a framework for the analysis of improvement trajectories in operations and technology management. In the first part, the concept of improvement trajectories in operations is defined, grounding on the evolutionary economic issues of path dependence and dynamic capabilities. In the second part, seven dimensions of the process and content of improvement trajectories are reviewed and integrated into a research framework, and research propositions are built to ground further research on the subject. In the third part, the roles of implementation history, innovation capabilities, and strategic orientation as determinants of improvement trajectory success are discussed. 相似文献

This article examines the relationship between the monetary policy implemented by the Central Bank of Brazil and the stock market. We implement event study analysis and analyze the effect of the anticipated and unanticipated components of monetary policy decisions on the returns of the IBOVESPA index and 53 stocks. We find that monetary policy has a significant effect on the stock market, but is only responsible for a small proportion of market variation. The analysis at the sector level with expected returns identifies that the financial sector is the most affected by this policy, whereas with excess returns only industrial goods are significantly affected. Moreover, individual assets respond in a rather heterogeneous fashion to monetary policy; however, when we look at excess returns, we identify a reduction in the intensity and in the number of companies impacted by monetary policy. Finally, the monetary shock is explained by unanticipated variations in the unemployment rate, in the Industrial Production Index, in the General Market Price Index, and in the Broad Consumer Price Index. 相似文献

ABSTRACT This article investigates the presence of herd behavior in Latin American stock markets using the methodologies proposed by Christie and Huang (1995) and Chang, Cheng, and Khorana (2000). Daily closing prices and trading volumes from January 3, 2000 to September 15, 2010 from the stock markets of Argentina, Brazil, Chile, Mexico, and the United States were analyzed. The US market was studied in order to provide a reference for comparison. The shares for which data was collected in each country were those listed in the most representative stock index for each market. It was not possible to establish evidence of herd behavior in any of the five countries studied using the Christie and Huang (1995) method. However, evaluating the data for the entire period using the method proposed by Chang, Cheng, and Khorana (2000) we detected herd behavior in the Chilean market. These results were not affected by the addition of additional exogenous variables representing the September 11 attacks of 2001 and the subprime crisis, or when the effect of the behavior of US shares on other countries was analyzed. Asymmetric herd behavior was detected in the Chilean, United States, Argentinean, and Mexican markets. 相似文献

Although a variety of models have been studied for project portfolio selection, many organizations still struggle to choose a potentially diverse range of projects while ensuring the most beneficial results. The use of the mean-Gini framework and stochastic dominance to select portfolios of research and development (R&D) projects has been gaining attention in the literature despite the fact that such approaches do not consider uncertainty regarding the projects’ parameters. This article discusses, with relation to project portfolio selection through a mean-Gini approach and stochastic dominance, the impact of uncertainty on project parameters. In the process, Monte Carlo simulation is considered in evaluating the impact of parametric uncertainty on project selection. The results show that the influence of uncertainty is significant enough to mislead managers. A more robust selection policy using the mean-Gini approach and Monte Carlo simulation is proposed. 相似文献
