While the biofouler Corbicula fluminea (Müller, 1774) is known to cause great economic losses in North America, studies reporting the problem in Europe are much scarcer. This paper explores the industrial effects of the species in Portugal, the gateway by which the bivalve entered Europe around 30 years ago. National waterworks, major power stations, cement plants, pulp and paper mills and irrigation systems were surveyed. The industrial impacts of the pest were shown to remain relatively mild; irrigation systems are those that seem to be facing more significant economic losses due to infestation. Possible reasons for the apparent discrepancy between this result and the species dispersal in natural ecosystems are discussed, and recommendations on adequate responses to the latent threat are provided. This study may assist the implementation of integrated pest management policies in countries at risk of invasion or recently invaded, and contribute to an understanding of the species’ progression in industrial environments.  相似文献

Firms grow and decline by relatively lumpy jumps which cannot be accounted by the cumulation of small, “atom-less”, independent shocks. Rather “big” episodes of expansion and contraction are relatively frequent. More technically, this is revealed by the fat-tailed distributions of growth rates. This applies across different levels of sectoral disaggregation, across countries, over different historical periods for which there are available data. What determines such property? In Dosi et al. (The footprint of evolutionary processes of learning and selection upon the statistical properties of industrial dynamics. Industrial and corporate change. Oxford University Press, Oxford, 2016) we implemented a simple multi-firm evolutionary simulation model, built upon the coupling of a replicator dynamic and an idiosyncratic learning process, which turns out to be able to robustly reproduce such a stylized fact. Here, we investigate, by means of a Kriging meta-model, how robust such “ubiquitousness” feature is with regard to a global exploration of the parameters space. The exercise confirms the high level of generality of the results in a statistically robust global sensitivity analysis framework.  相似文献

We empirically examine whether adopting a uniform set of accounting standards mitigates information frictions in financial markets and facilitates market integration. Using a difference‐in‐difference design, we find that after the mandatory adoption of IFRS local stock returns incorporate more global information and at a faster speed. The effect of IFRS adoption is stronger in countries where there are larger improvements in accounting comparability and for firms with a larger increase in foreign ownership. Overall, our results suggest that accounting standards harmonization facilitates financial market integration.  相似文献

Recently, the global economy assumed a new setting in which emerging economies began to make substantial investments in the international market. This study aimed to investigate the determinants of outward foreign direct investment from Brazil from 2002–2011. The proposed models developed included attractiveness of the host country, characteristics of home country, and firms’ strategies. The results corroborate the existing argumentations concerning adaptation of mainstream theory with respect to the realities of emerging economies. Brazilian multinationals do not internationalize their activities in pursuit of cost reduction, efficiency, or to explore new markets or natural resources of the host countries. Results show that Brazilian investments were attracted by the availability of skilled labor, openness of the host market, geographic proximity, improved financial conditions of Brazilian companies, and national companies’ strategy of reaffirmation and consolidation as global players.  相似文献

China is rapidly becoming an important market for consumer goods, but relatively little is known about variations in consumer shopping patterns in different regions of China. We employ a cultural materialism perspective in understanding decision-making styles of inland and coastal shoppers. Our findings reveal that consumers in the two regional markets do not differ in utilitarian shopping styles but they do in hedonic shopping styles. Marketers need to understand these differences to be able to market effectively to consumers in different regional markets within China.  相似文献

The perception of the causes of poverty has long been recognized as a very important factor in the broader study of this social phenomenon. This study covers 15 European Union countries and considers three types of poverty attributions: individualistic, societal, and fatalistic. The individualistic view perception believes the poor are responsible for their situation, the societal perspective blames society for poverty and the fatalistic view considers poverty to be the result of bad luck or fate. A multilevel mixture model with three clusters of countries and six clusters of individuals was identified. Despite the generalization of the social explanations of poverty at the individual or micro level, there are also groups that emphasize more individualistic explanations, blaming the poor for their condition. At the country or macro level, the most developed cluster believes in the individualistic and fatalistic causes of poverty, whereas the least developed clusters explain poverty based on the injustices of society. There is diversity in the way these countries perceive poverty.  相似文献
