With the increased interest in the ‘carbon footprint’ of global economic activities, civil society, governments and the private sector are calling into question the wisdom of transporting food products across continents instead of consuming locally produced food. While the proposition that local consumption will reduce one’s carbon footprint may seem obvious at first glance, this conclusion is not at all clear when one considers that the economic emissions intensity of food production varies widely across regions. In this paper we concentrate on the tradeoff between production and transport emissions reductions by testing the following hypothesis: Substitution of domestic for imported food will reduce the direct and indirect Greenhouse Gas (GHG) emissions associated with consumption. We focus on ruminant livestock since it has the highest emissions intensity across food sectors, but we also consider other food products as well, and alternately perturb the mix of domestic and imported food products by a marginal (equal) amount. We then compare the emissions associated with each of these consumption changes in order to compute a marginal emissions intensity of local food consumption, by country and product. The variations in regional ruminant emissions intensities have profound implications for the food miles debate. While shifting consumption patterns in wealthy countries from imported to domestic livestock products reduces GHG emissions associated with international trade and transport activity, we find that these transport emissions reductions are swamped by changes in global emissions due to differences in GHG emissions intensities of production. Therefore, diverting consumption to local goods only reduces global emissions when undertaken in regions with relatively low emissions intensities. For non-ruminant products, the story is more nuanced. Transport costs are more important in the case of dairy products and vegetable oils. Overall, domestic emissions intensities are the dominant part of the food miles story in about 90 % of the country/commodity cases examined here.  相似文献

on the basis of the self-organizing theories the thesis analyzes how enterprises realize the stride development through the technology stride. At First the thesis sets up the stride development system of enterprises and then the thesis reveals the mechanism that the technology stride will give rise to the stride development of ente~fises. In the end the thesis puts forward the enlightenment for the stride development of enterprises from the stride development system of enterprises.  相似文献

Intensive agriculture is often bad for wildlife. Does this imply that a goal to boost wildlife on agricultural land is best met through a general reduction in intensity? We argue that such an approach may not be optimal, since cost functions for provision of wildlife on agricultural land may be non-convex, due to fixed costs associated with such provision. This implies that, even when farms are identical, it may be preferable to split them into groups of high providers and low providers. We test our hypothesis in a study of the optimal management of mown grasslands in southern Sweden, where the two products are silage and successful reproduction of ground-nesting birds, and the variable controlled by the farmer is the date of the first mowing. We show that the optimal solution is likely to involve some farmers maintaining profit-maximizing practices while other—identical—farmers delay their first mowing significantly. The superiority of such split solutions may have major implications for agricultural policy.  相似文献

The ambient tax is often considered as an efficient instrument to achieve a first best outcome of ambient pollution when the regulator cannot observe individual emissions, or when monitoring costs are prohibitive. While this view is supported to a large extent by experimental findings, there remains several hurdles that hinder the implementation of the ambient tax in the field. One of these hurdles is the nature of the damage. Experimental findings suggest that the efficiency of the ambient tax is higher under external damage, i.e. if ambient pollution affects non-polluters (Spraggon in J Public Econ 84:427–456, 2002) than under internal damage, i.e. if ambient pollution affects polluters themselves (Cochard et al. in Environ Resour Econ 30:393–422, 2005). But this result rests on very different experimental settings. Therefore, we designed a new experiment that allows to compare external and internal damage within a common setting. Our main finding is that the ambient tax is equally efficient under internal and external damage.  相似文献

There exists a rule of thumb of mines, which decides how the cut-off grade (the lowest grade of extracted ore) should change in response to a change in the price of the metal. It requires that the cut-off grade should decrease (increase) when the present value price of metal increases (decreases). In this paper, the optimality of the rule will be examined by generalizing the Cairns–Krautkraemer model under the perfect foresight assumption.  相似文献

Merger is a kind of strategic behavior of seeking long-term development. A new enterprise coming from merger is different from the one that come into existence. The strategy of new enterprise formed from merger is constituted through the integration of the strategy for each side. Strategy integration is the guide for the integration of other elements after merger, the way for enterprises to adapt the change of environment and the warranty for the enterprises to achieve strategy synergistic effect. Strategy integration of the merging-enterprises can be realized through several steps: preparation for strategy integration, readjustment to strategy, reorientation of the enterprise and effective communication with target enterprise in the course of carrying out the strategy.  相似文献

The changing geographical foci of the geopolitical code of the United States are examined by a content analysis of the presidential State of the Union Speeches between 1988 and 2008, the last year of President Reagan's term through the presidency of George W. Bush. The State of the Union speeches are interpreted as geopolitical discourse within a structural setting, using seven foreign-policy paradigms as an organising framework. The empirical findings illustrate an increase over time in the number of regions and countries mentioned in the speeches. Also, notable differences between administrations in terms of their advocacy of globalist or regionalist policies and emphasis upon allies or adversaries are found.  相似文献

With the reform of the state-owned enterprises, the level of the human resources management of a lot of state-owned enterprises has been gradually improved. However, because of the macroscopic system, history, culture and their own reasons, there are still a series of problems in the human resources management of state-owned enterprises. In order to promote the reform of state-owned enterprises and to improve the competitiveness of enterprises, we should critically research these urgent problems. The paper will take an example of one company which was investigated by state-owned enterprises will be listed and analysed. the author, and the common problems which exist in most state-owned enterprises will be listed and analysed.  相似文献

Based on the sample data of the listed firms on the A stock market, we analyze how the system of independent directors influence the earning conservatism from 4 dimensions designed to measure the monitoring power of these independent directors: Percentage within BDs, professional capacities, stimulation and work conditions. From the empirical results, we conclude that the more powerful of the independent directors, the better the accounting conservatism, and that their positive impact increases along with the improvement on corporate governance, meanwhile the work conditions plays the most important role, and then are the percentage within BDs and their professional capacities, the stimulation and personal reputation appear the least importance.  相似文献

In the wake of the Single European Act of the mid-1980s and a series of follow-on initiatives aimed at fostering greater integration in Europe, a number of commentators began describing Europe as a truly novel political-territorial arrangement. By the middle of the 1990s, however, the adoption of a common currency came to dominate the European integration agenda. The embrace of monetary union reflected a view of European integration that was firmly embedded in the logic of the modern territorial state system. That logic led many commentators to view the success or failure of integration in terms of the degree to which powers were being transferred from state governmental and economic institutions to the central decision-making bodies of the European Union. Such an approach cast the EU as a super-state rather than as a new type of political-institutional entity. As a result, the integration project was less subversive of the state system than it might otherwise have been – bolstering the view of the European Union as a distant bureaucracy not adequately attuned to the needs of everyday Europeans and fueling nationalist sentiments: a social force with deep roots in the modernist territorial order. Moving the European integration process forward will likely require embracing conceptions of progress that are less tethered to modernist territorial ideas and assumptions.  相似文献

Capital structure is one of the important research aspects of corporate finance. According to methodology, the capital structure research can be classified into two categories: the paradigm of uni-corporation and the paradigm of industry organization. Traditional capital structure research can be attribute to uni-corporation aspect. This paper reviews all literatures concerning the paradigm of industry organization and illustrates the inter-relationship among the feature of industry, the feature of suppliers and customers, the competitive strategy, product life cycle and capital structure.  相似文献
