The contemporary confluence of globalization and ethical pluralism is at the origin of many ethical challenges that confront business nowadays, both in practice and in theory. One of the challenges arising from the development of globalization has to do with respect for cultural diversity. It is often said that the success of economic globalization tends towards social and cultural homogeneity. To the extent that cultural diversity is usually seen as a valuable reality, that global trend seems to contradict our efforts to respect ethical pluralism, both personal and cultural, within society. In this paper I argue that (a) ethical minimalism, despite its emphasis on tolerance and justice, does not take pluralism seriously into account in present-day society, and (b) ethical minimalism is not suited to balancing the homogenizing trend of globalization. Certainly ethical norms are necessary, but by no means are they sufficient in themselves to encourage either justice or tolerance; nor are they sufficient to inspire and encourage good practices and sound regulations. Instead, virtue-based ethics has the capacity of inspiring and encouraging good practices. Particularly, virtue-based ethics is able to inspire a serious dialogue about ethical and legal issues both in the public arena and within organizations. 相似文献

The literature on stochastic input–output (I–O) analysis has paid considerable attention to the bias in the Leontief inverse. This paper extends previous studies by assuming supply and use tables (SUTs rather than I–O tables or input coefficients matrices) to be stochastic. This is a natural starting point because SUTs have become the basic data sources for I–O applications. In a Monte Carlo simulation experiment, a given SUT is randomized in two different ways and the effects are determined for eight different multiplier matrices. The analysis is carried out for Spain, Italy, the Netherlands, Germany and Finland, using their SUTs for 2006. The findings indicate that, in general, biases are statistically significant but negligibly small. This corroborates earlier findings obtained for stochastic I–O tables. 相似文献

We study the optimal timing of adoption of a cleaner technology and its effects on the rate of growth of an economy in the
context of an AK endogenous growth model. We show that the results depend upon the behavior of the marginal utility of environmental
quality with respect to consumption. When it is increasing, we derive the capital level at the optimal timing of adoption.
We show that this capital threshold is independent of the initial conditions on the stock of capital, implying that capital-poor
countries tend to take longer to adopt. Also, country-specific characteristics, as the existence of high barriers to adoption,
may lead to different capital thresholds for different countries. If the marginal utility of environmental quality decreases
with consumption, a country should never delay adoption; the optimal policy is either to adopt immediately or, if adoption
costs are “too high”, to never adopt. The policy implications of these results are discussed in the context of the international
debate surrounding the environmental political agenda.

The univariate statistical properties of agricultural price series need to be examined as a first step in the analysis of price transmission mechanisms. However, in the case of weekly price series, increasingly available, the testing procedures usually applied in this step are not suitable to deal with evolving seasonal effects. In this study, a method of testing for seasonal unit roots in weekly series of agricultural prices is described. When the deterministic seasonal component does not remain constant over time, the restricted evolving spline model (RESM) is shown to be a useful parametric formulation to capture the deterministic seasonal pattern. Therefore, the RESM model should be included as a deterministic component in auxiliary regression for unit root tests at seasonal frequencies. This proposal is applied to three weekly series of Canary Islands banana prices. From the standard seasonal unit root tests, the null hypothesis is failed to be rejected at the 5% or 10% significance level at some seasonal frequencies for each one of the series. Once critical values are obtained by simulation exercises when the RESM model is included, the hypotheses of unit root are rejected at each one of the seasonal frequencies for all of the three series. 相似文献

This study analyses the effect of the spatial factor, location, and interaction effects among peer companies, on the productivity growth of agri‐food companies in Spain. With this aim, we build a productivity growth index and apply a multiequational Seemingly Unrelated Regression on a sample of 344 Spanish cooperatives and investor‐owned firms for the period 2010–2012. Our findings show that agri‐food firms are influenced by spatial factors finding interesting differences between cooperatives and investor‐owned firms. With regard to the geographical location, cooperatives in the western of Spain show higher productivity growth rates, whereas investor‐owned firms in the northeast of Spain present better results. The interaction effect among closer peer companies is also a relevant factor to determine the productivity growth in agri‐food companies. This factor is more relevant for cooperatives than for investor‐owned firms. 相似文献

Socio‐economic transitions and everyday life changes in the rural world: Pyrenean households and their contemporary economic history

This article focuses on understanding rural life and how agrarian everyday life changes as a consequence of the radical socio‐economic transformations that, across the world, have accompanied rural communities in their transition from economies of subsistence to industrial production, and, in some areas, from there to providers of service to the tourism‐oriented leisure economy. In the last century in the Alt Urgell District (Spanish Pyrenees), many communities went from a production model based on subsistence farming and livestock breeding first to a specialization in milk production and later to tourism. The industrialization of milk production, the radical transformation of the scale of their operations, and the monetization of life transformed the identity and structure of these communities. The subsequent transformation of many of these farms to accommodate the leisure industry changed the shape of these households again. This paper reflects on how science, governance, commodification, and technology played a role on the transformation of the rural mountain areas, their people, and their everyday life. 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

Reinsurance allows insurance companies to diversify their risks. However, from this original role, insurance companies have developed various reinsurance strategies in order to expand their market share. From the last decades of the nineteenth century to the 1940s, Spanish insurance companies used reinsurance in a largely unregulated context. This article analyses the reinsurance practices and their adaptation to the singularities of the Spanish market, namely: the difficulties for the consolidation of a core of pure reinsurers; the management of reinsurance in the internationalisation process; and the use of reinsurance by mutual societies to overcome their lack of equity capital. 相似文献
