Given the interplaying tendencies of economic decline, social instability, and environmental depletion, any transition towards sustainable development faces a challenging task. To successfully cope with this complexity requires transition management. Integrated approaches for supporting sustainability transitions have been elaborated in the last years. Future studies and scenario construction are regarded as essential components in these approaches. However, the related studies in this field have focused either on a specific type of transition process, or on decision support in a different contextual process, or on a specific function of scenarios. Thus, an evaluation of the wide range of viewpoints on the functions of scenarios with respect to the requirements for transition management is still missing. In this paper, we systematically elaborate upon the functions for transition management that scenarios can fulfil. The developed concept is applied to five empirical scenario studies supporting transition processes on the national, regional and local level in Switzerland. The paper contributes to the development of a functional methodology of transition support, providing initial guidelines for answering the question of which method is appropriate for what type and phase of a transition process. 相似文献

The objective of this study is to determine if there are important size and industry effects on financial performance of agricultural cooperatives. The performance of 43 dairy, food, grain, and farm supply cooperatives in the U.S. was analyzed over the period 1970-1987 using financial ratios derived from accounting data. The analysis revealed significant size and industry effects. Large regional cooperatives are more efficient in utilizing their assets to generate sales, while small regional cooperatives have higher profitability. The findings suggest that the emphasis on growth may not always produce beneficial results among agricultural cooperatives. Among the four industries studied, the dairy regional cooperatives appear to be the strongest performers, while the food marketing cooperatives are characterized by the lowest performance measures. Since both dairy and food cooperatives engage in value-added processing, this difference in performance makes it difficult to reach clear conclusions about possible advantages of disadvantages or vertical integration relative to traditional cooperative activities. Trend analysis indicates that the profitability of the agricultural cooperatives in all industry and size categories declined in response to the downturn in U.S. agriculture after 1980. While the decline in profitability was at similar rates for both large and small cooperatives, the variation of efficiency and leverage was in opposite directions. Large cooperatives may be expected to continue improving their asset utilization without relative improvement in profitability, and increasing the level of their debt in relation to equity. 相似文献

A bootstrapped DEA procedure is used to estimate technical efficiency of 18 Italian airports during the period 2000-2004. Departing from previous studies, we separate the efficiency related to ability to manage airside activities (operational) from that related to the management of all business activities (financial). In general, Italian airports operate at poor levels of efficiency, with slightly better performance in terms of their financial activities. In the current study, selected intrinsic and environmental characteristics are considered as possible drivers of Italian airport performance. In particular, we found that: (i) the airport dimension does not allows for operational efficiency advantages, (ii) on the other hand, the airport dimension allows for financial efficiency advantages for the case of hubs and disadvantages for the case of the smallest airports (iii) the type(s) of concession agreement(s) might be considered as important source of technical efficiency differentials for those airports running marginal commercial activities; (iv) the introduction of a dual-till price cap regulation might create incentives which lead to the increase of financial efficiency at the detriment of the operational performance. Lastly, the development of a second hub (Milano Malpensa), has negatively affected the performance of the country’s national hub (Roma Fiumicino). 相似文献

Globalization has affected business cycle developments in OECD countries and has increased activities of firms across national
borders. This paper analyzes whether these two developments are linked. We use a new firm-level data set on the foreign activities
of German firms to test whether foreign activities are affected by business cycle developments. We aggregate the data by the
sector of the reporting firm, the sector of the foreign affiliate, and the host country. Data are annual and cover the period
1989–2002. We find that German outward FDI increases in response to positive cyclical developments abroad and in response
to a real depreciation of the domestic currency.

Urban families in the late nineteenth century depended upon their children as their most important source of labor income apart from the male head of house-hold. This paper explores the determinants of the labor force participation of children over 10 years old within the context of the economic theory of household and market production, using microlevel data from 1880 Philadelphia. The father's income and unemployment, the presence of the mother or father, boarders, servants, older and younger siblings, parents' literacy, and ethnicity, among other variables, are used in a probit analysis of the labor force participation of children. The results validate the economic theory of household and market production demonstrating, in particular, substitution between mothers and their daughters and the role of comparative advantage in family decisions concerning the allocation of their members' time. Ethnic differences were only important for daughters. 相似文献

Abstract. Recent literature on multinational firms has focused on low productivity as a barrier to the internationalization of firms. But labour market frictions or financial constraints may also hamper internationalization. In order to assess the importance of these barriers, we present new empirical evidence on the extensive and intensive margin of exports and foreign direct investment (FDI) based on micro‐level data of German firms. First, we find a positive impact of firm size and productivity on firms’ international activities. Second, labour market frictions can constitute barriers to foreign activities. Third, self‐reported financial constraints have no impact on firms’ internationalization decisions. JEL classification: F23, G2 相似文献

This paper presents an empirical analysis of the impact of climate change on agriculture in a typical developing country. The economic implications of climate change are estimated by using both a farm productivity and a Ricardian framework. Data are drawn from about 1,000 farms producing cereal crops in the Nile Basin of Ethiopia. The thin plate spline method of spatial interpolation was used to predict household specific rainfall and temperature values using meteorological station data collected for 30?years across the regions. We found that climate change adaptation has a significant impact on both farm productivity and farm net revenues. We complement the analysis by providing an estimation of the determinants of adaptation. Extension services (both formal and farmer to farmer), as well as access to credit and information on future climate changes are key drivers of adaptation. 相似文献

A preferred customer is a buying organization who receives better treatment than other customers from a supplier, in terms of product quality and availability, support in the sourcing process, delivery or/and prices. The decision to become a preferred customer implies a continuous commitment by the purchaser to a complex, expensive and often uncertain process. It is important to use a strategic approach, as well as appropriate tactics. Based on well-known models on the development of buyer-supplier relationship, on customer portfolio analysis and on the emergent literature in customer attractiveness and preferred customer status, we suggest four steps to become – and remain – a preferred customer: initial attraction, performance, engagement and sustainability. The process takes the perspective of a buyer willing to obtain the preferential status and focuses on the strategies and tactics that could influence the supplier's decision of granting this status. The proposed process considers that the supplier is continuously comparing the value offered by the customer to its expectations, and to the value offered by other customer relationships. 相似文献
