The ongoing harmonisation of the European energy sector has led to gains from growth and increasing efficiencies by creating a common European internal market. However, there are new tendencies running against harmonisation in recent years, currently for example in the area of climate protection and the associated expansion of renewable energies. In addition to the role of national targets for climate protection in combination with a European emissions trading system, carrying out the related measures leads to distributional effects, both between countries and between stakeholders (e. g., producers and consumers) in these countries. We first analyse the impact of a non-harmonised national promotion schemes for renewable energies on electricity and CO2 prices in different countries. Then we illustrate the impact of harmonisation measures on producers and consumers in the participating countries. The analysis shows that these measures are indeed economically beneficial, but that—depending on the actual configuration—they can also lead to disadvantages for individual actors. Analysing and discussing these effects leads to a better assessment of the impact of certain measures and enables a better classification of individual market participants’ responses and opinions.  相似文献

This paper examined climate change adaptation strategies in fish farming and the effect of such methods on the profit of fish farmers in the Niger Delta region of Nigeria, Africa’s most populous country. Using cross‐sectional data obtained from 420 fish farmers from the region and applying multivariate probit and instrumental variable regressions, the study found that fish farmers have adopted a broad range of strategies to address climate risk and that these have significantly increased farmers’ profit. Our findings indicated important relationships between certain farm, socio‐economic and institutional characteristics and the adaptation actions. The study provides useful insight into factors that potentially encourage the adoption of livelihood‐enhancing climate risk adaptation strategies by fish farmers in the Niger Delta region and similar contexts.  相似文献

Urban regions are important places of ecosystem service demands and, at the same time, are the primary source of global environmental impacts. Although there is broad agreement on the importance of incorporating the concept of ecosystem services into policy strategies and decision-making, the lack of a standardized approach to quantifying ecosystem services at the landscape scale has hindered progress in this direction. Moreover, tradeoffs between ecosystem services and the supply/demand ratio of ecosystem services in urban landscapes have rarely been investigated. In our paper, we present a method to quantify and map the supply and demand of three essential provisioning services - energy, food, and water - along the rural-urban gradient of the eastern German region Leipzig-Halle. This urban region has experienced significant socio-economic dynamics and land use changes since the German reunification in 1990. The results show that both the demand and the supply of ecosystem services changed considerably during the time span under consideration (1990-2007). We identified an increasing supply/demand ratio of food and water but a decreasing supply/demand ratio of energy. In addition, the pattern of ecosystem demands shows a levelling of rural-urban gradients, reflecting profound modifications of traditional rural-urban relationships. The changes of ecosystem service supply gradients are determined more by land use intensity, such as the intensification of agricultural production, than by land cover changes such as urban sprawl. The comparison of supply/demand ratios and rural-urban patterns of ecosystem services can help decision-makers in landscape management in striving for a sustainable balance between resource supply and demand.  相似文献

Using a generalized error correction model, this article measures and compares market integration for export cash crops versus imported food crops for Mali and Nicaragua, and computes transmission elasticities between changes in the goods’ border and domestic prices. Both Mali and Nicaragua obtain the bulk of their export revenue from a particular agricultural commodity—cotton for Mali and coffee for Nicaragua—and both import the same key staple food of rice. To reap the economic gains from this trade specialization, the two countries’ agriculture must be well‐integrated into world markets. The two countries present an important policy contrast that affects their degree of world market integration and price transmission. In Mali, a parastatal enterprise controls its cotton industry, while Nicaragua has less state direction over agriculture. Reflecting this difference, the results show that for both its main export and import commodity, Nicaragua is more integrated into world markets and has higher price transmission than Mali. The results for Nicaragua also show much higher integration and price transmission for its main agricultural export (coffee) than its major import (rice).  相似文献

This article examines the institutional strategies of multinational enterprises (MNEs) operating in an emerging market, drawing attention to how longstanding foreign subsidiaries proactively negotiate their involvement with socio-political actors. We build on institutional logics to explain how MNE subsidiaries develop sustained political, cultural, and cognitive embeddedness. Using an inductive, interpretive study of four century-old Dutch MNE subsidiaries with a colonial legacy in Indonesia, we examine these three dimensions of the institutional environment, finding that local employees embedded in both the MNE and the host country sets of logics ‒ rather than expatriate managers ‒ most effectively facilitated sustained institutional embeddedness. Our findings also suggest that embedding practices in host institutional contexts and developing structures that align with host institutional expectations provided a platform for the unfolding of institutional strategies by local employees. However, MNE subsidiaries face contrasting logics between home and host country institutions, placing significant strains on MNEs’ ability to enact change.  相似文献

Summary During the crisis of 1974/75 the number of foreign workers in Western European countries has been reduced. This has caused a new discussion about the benefits and drawbacks of the employment of foreign workers. Whatever the attitude towards this problem may be, it is useful to decompose the reduction of foreign labour into categories. First of all a certain amount of foreign labour will be reduced due to a general decrease of overall employment. This influence may be called proportionality effect. The share of foreign workers in the different branches of the economy allows the calculation of a structural effect. Both of them measure influences, which concern foreigners as well as nationals. Only the remaining influence is specific to foreigners. It may again be split into a reduction effect and a substitution effect. The former ist concerned with that part of total reduction of foreign workers, which corresponds to the decrease of employment, i.e. employment reduction by dismissal of foreign workers. The latter pertains to that part of reduction, which exceeds the decrease of employment, i.e. by this magnitude domestic labour has been substituted for foreign labour.The application of this model to the years 1974 and 1975 shows no proportionality effect (1974 it is even positive), a limited structural effect, but a high reduction effect. The substitution effect is considerable in 1974 but of minor importance in 1975. So foreign labour in Austria served actually as cyclical buffer but mainly by reduction and only partly by substitution.  相似文献

ABSTRACT

This article investigates the impact of corporate governance on bank efficiency across a sample of 139 commercial banks from 17 countries of Central and Eastern Europe during the period 2005–2012. Data on governance characteristics are hand-collected from banks’ reports. The empirical findings indicate that implementing rigorous corporate governance structures is associated with higher costs for banks and a lower level of efficiency. However, during the crisis, a tight governance mechanism significantly increases banks’ cost and technical efficiencies. We also show that prudent risk management is associated with both higher cost and technical efficiency for more capitalized banks, while rigid supervisory boards are linked with greater technical efficiency for more capitalized banks.  相似文献

Motivation and productivity were increased when the traditional division of labour and surplus was modified to give workers extended tasks and profit-shares in firm Z. In X, traditional division of labour combined with worker-shareholding and formal, representative participation failed to improve motivation.  相似文献

Information feedback is a much debated issue on balancing power markets: which information on past auctions should be published and when? The article analyzes advantages and disadvantages of different feedback policies applied to the example of the Swiss balancing power market. Our main conclusion is that the publication of the marginal bid is usually recommendable. This is often not the case for additional information (e.g. extramarginal bids). However, the answer depends on the specific market design and the market structure.  相似文献

Abstract . Brain drain occurs when skilled individuals leave their native countries. It is often argued that this phenomenon has strong negative effects on the countries of origin, preventing them from capitalizing on their investment in human capital formation and thus realizing a higher growth. This analysis shows that the negative consequences of brain drain have been overemphasized, mainly because of the confusion between capital and technology. It demonstrates that investments in human capital are possible and profitable in a free market. State intervention in education is responsible for the systematic misallocation of human capital in general, and for brain drain in particular.  相似文献
