There is currently much debate in the economic literature about whether ethical investment involves a financial sacrifice
or premium. One of the most common methods of testing this compares the financial performance of ethical investment funds
with that of other funds not considered “socially responsible” or ethical. The majority of these research studies evaluate
the performance of the ethical funds according to classic measures, whereby different financial markets, in different countries
and for different periods of time serve as reference for evaluation. The ultimate conclusion of all of these studies is that
there are no significant differences between the performance results of one type of funds and the other. In Spain, ethical
investment funds are still an incipient sector of investment. To date, the Spanish market has not been included in any type
of analysis of these characteristics. Therefore the main objective of this article is to compare the financial performance
of ethical investment funds to that of other funds in the Spanish retail market. We propose the aggregate type of analysis
as the Spanish ethical investment funds have experienced a weaker development in comparison to those of other developed countries.
In the first step we suggest the financial performance to be compared by style analysis since the asset distribution of the
Spanish Social Return Investment (SRI) funds differs from the European trend. In particular, we use the multifactor regression
model with style benchmarks. We found that their financial performance is in all cases superior or similar to that achieved
by the rest of the funds. In the second step, to achieve a more robust and homogeneous comparison, we used the bootstrap method,
comparing ethical and non-ethical fund subsamples by homogeneous groups. No significant differences between these two types
of funds have been found. Thus, if we assume the positive o neutral effect of ethical investment on investor utility in the
retail Spanish market the financial and social performance (FSP) of ethical funds will be, in aggregate, superior to the FSP
achieved by conventional funds. In conclusion, the financial performance of ethical mutual funds in Spain is no sacrifice. 相似文献

This paper is devoted to the analysis of the estimation of the mean of a sensitive variable. The use of a randomized response
(RR) procedure gives confidence to the interviewed that his privacy is protected. We consider that a simple random sampling
with replacement design is used for selecting a sample. The behavior of the RR procedure, when ranked set sampling is the
design used, is developed under three different ranking criteria. The usual gain in accuracy associated with the use of ranked
set sampling is exhibited only by one of the designs. The behavior of the models is illustrated using data provided by a study
of samples of persons infected with AIDS. 相似文献

Stated preference methods can be used to estimate the demand function where no price variation has been observed before. This is the situation of the Mexican coral reef natural protected areas, where after the 2002 approval of a $20 pesos fee (US$1.80) the Ministry of the Environment is now considering increasing the amount of the fee, not only to raise more revenue for the park, but also to curb the number of visitors in the cases where there is excess demand. There are concerns that the very success of the reefs is bringing associated environmental damage that threatens its sustainable use. To estimate the reaction of visitors to different fee levels, we carried out a contingent valuation survey, and constructed with its results an aggregate demand for each park. This demand was then divided by seasons and nationalities, to explore the benefits and costs of differentiating fees, looking at both the revenue maximising and the welfare maximising fees. Finally we discuss how these fees would change when environmental damage functions are taken into account. The recommendation is that increasing fees up to the point where they cover both private and environmental costs would bring the highest amount of economic benefit compatible with the sustainable use of these complex and wondrous marine ecosystems. 相似文献

This article looks at the efficiency of Portuguese tour operators focusing on firm size, group ownership, and mergers and acquisitions. It has been argued that changed market conditions in Europe make it hard for tour operators to achieve economies of scale and market growth without increasing firm size or being part of a more high profile company. 相似文献

This paper analyses the relationship between the presence of organized labour in firms (approximated by the scope of collective bargaining) and the extent of gross worker and job flows. According to the voice theory of Freeman, those firms having a union presence will have lower worker mobility. However, there is no analysis of the effects of the presence of organized labour on gross job flows. Using a Spanish data base, we find evidence of the existence of a voice effect on gross worker flows but not clear support for a voice effect on gross job flows. 相似文献

Using data from the population of Ecuadorian importers, we examine the extent to which the characteristics of their imports relate to their labor productivity. Results indicate that the technological intensity of imports does not explain differences in labor productivity, although the region of origin of imports explains differences in the manufacturing sector, as imported technologies from advanced regions are associated with superior labor productivity. Nevertheless, as technology intensive imports are not associated with superior performance, we argue that importers from developing countries may use foreign technology inexpertly due to the lack of absorptive capacity and the emerging nature of their national innovation system. 相似文献

Using the lenses of institutional theory, this study examines several Entrepreneurial Factor Conditions (National Experts Survey database) while focusing on potential differences of several institutional dimensions between factor- (or production) and innovation-driven countries. This study therefore examines first the extent to which several Scott’s institutional variables (normative, regulative, and cultural-cognitive) differ according to the economic structure of countries participating in NES-GEM. Results indicate that the relevance of both regulative and cultural-cognitive dimensions differ between the group of countries driven by factor (or production) versus innovation, with a single exception, the normative dimension. Second, the study fine tunes the analysis and examines the extent to which the relevance of the aforementioned dimensions differs in two distinct institutional contexts (Portugal and Angola). Results show that the relevance of all institutional variables is different except one, the basic education and training. A possible explanation for these results may be associated to the lack of and fragility of several institutions and the absence of norms and regulations needed for a well-functioning economy, particularly in what concerns the factor (or production)-driven countries. In terms of originality, the study addresses an area of the GEM model that is under-researched. 相似文献

The Nigerian banking consolidation process is examined using a dynamic panel for the period 2000–2010. The Arellano and Bond (1991) dynamic general method of moment approach is adopted to estimate a cost function taking into account the possible endogeneity of the covariates. The main finding is that the Nigerian banking sector has benefited from the consolidation process, and specifically that foreign ownership, mergers and acquisitions, and bank size decrease costs. Directions for future research are also discussed. 相似文献

As the relative effectiveness of physical resources decreases toward parity with rivals due to their fungibility, the firm's marketplace position, established by managers with a particular set of inter-culturally attuned set of personal values, may be the key antecedent in creating competitive strength in the firm. The research question addressed is how creative are culturally diverse managers; are managers from certain countries more creative than adaptive?We tested hypotheses in a cross-cultural setting based on the survey responses of 1365 managers operating in eight countries located in four culturally diverse regions of the world.Our study shows that managers are both creative and adaptive but the mixture of creative and adaptive behaviour varies depending on region and country and even within countries. Furthermore, the results confirm that creativity among managers in some countries is similar but large differences also exist between countries. 相似文献
