This paper is dedicated to the empirical exploration of the welfare effect of expectations and progress per se. Using 10 waves of the Russian Longitudinal Monitoring Survey (RLMS), a panel household survey rich in subjective variables, the analysis suggests that for a given total stock of inter-temporal consumption, agents are more satisfied with an increasing time profile of consumption: they seem to have a strong “taste for improvement”. This contributes to qualify the “Easterlin paradox” that income growth does not make people happy.  相似文献

Since the middle 1990s, ecotourism certification has been given more and more attention to around the world.As a developing country with abundant ecotourism products, it is necessary for China to adopt certification to ensuresustainable development of ecotourism. But there are few products certificated until now in China. After reviewing thetrend of ecotourism certification in the world and summarizing its theory and method, this paper analyzes the progressand prospect of ecotourism certification in China, and concludes that certification in China is necessary and promising.  相似文献

Definitions and progress of ecosystem health and ecological security   总被引:2,自引:0,他引:2  
1. Introduction Development of human industrial civilization and predatory exploitation of natural resources have in- duced tremendous changes of ecological environment. In recent years, territorial and global environmental problems have increased, such as greenhouse effect, depletion of ozone, global warming, water scarcity, water pollution, acid rain, decrease of biodiversity, soil erosion desertification etc. These changes seriously intimidate the health and security of ecosystems, and dist…  相似文献

We use longitudinal tax data linked to immigrant landing records to study the effect of selective attrition on the estimated earnings assimilation of immigrants to Canada. Contrary to findings in the existing international literature, we show that the immigrant‐native earnings gap closes at the same pace in longitudinal and cross‐sectional data. Low‐earning immigrants are likely to leave the cross‐sectional samples over time, but the same is true for the native born. Our study suggests that immigrants to Canada have labour market participation dynamics similar to those of the native born.  相似文献

Sustainability concepts that rest on the idea of resource- or energy-efficiency improvements due to technological progress tend to overestimate the potential saving effects because they frequently ignore the behavioral responses evoked by technological improvements. Efficiency improvements also affect the demand for resources and energy, and often an increase in efficiency by 1% will cause a reduction in resource use that is far below 1% or, sometimes, it can even cause an increase in resource use. This phenomenon is commonly labeled the rebound effect, which is well-known among energy economists, but never attracted much attention in ecological economics. The paper starts with the traditional neoclassical analysis of the rebound effect in a partial equilibrium framework that concentrates on the demand of one particular energy service such as mobility or room temperature. It also provides an overview of some of the main empirical studies based on this model that mostly confirm the existence of the rebound effect, but are controversial about its actual importance. However, we have to go beyond the neoclassical single-service model in order to take care of the variety of possible feedback affecting energy use. The paper presents two important expansions of the single-service model in order to show the potential relevance of the rebound effect to ecological economics. First, it is shown that in a multi-services model it proves to be difficult to make general statements about the relevance of the rebound effect. In this case, the overall effect of an increase in energy efficiency on total energy use depends on the on the assumptions about the substitutability between the services considered and the direction of the income effect. Second, the paper also tries to take care of the fact that changes in resource use or energy use are frequently just ‘side-effects’ of other forms of technological progress. Especially technological change of a time-saving nature can have a large influence on energy use as many time-saving devices (for example, faster modes of transport) require an increase in energy consumption that is frequently reinforced by a ‘rebound effect with respect to time’. This effect will be especially strong when wages are high and, at the same time, energy prices are low, as is currently the case in most industrialized countries. Consequently, the paper also provides a strong argument for the introduction of energy taxes.  相似文献

The peri-urbanization area as a kind of rural-urban interface is changing rapidly ,physical, economlc and social terms. The land use pattern in such area is shifting away from the assumptions of mainstream paradigms to new conceptual landscapes, which leads to a series of problems on economic development and social stabilization. There are many researches on non-agricultural land-use in peri-urbanization area. In this paper both international and domestic research literature is reviewed by dividing six parts. The first part introduces the conception of peri-ur-banization area and its driver factors. Then in the second and the third part, the paper expatiates on the progress in the non-agricultural land-use in peri-urban area on land-use problems in the research area, while the fifth part reviews the integrating ways of non-agricultrual land-use. Finally, recommendations for further study are draw with specific reference to the current and future position of non-agricultural land-use study in peri-urban area.  相似文献

Involuntary resettlenment caused by project construction is a difficult problem over world. In the past, therestoration of livelihoods in the event of involuntary resettlementhas been based purely on providing compensation to those who are displaced. Evidence has shown that compensation-based involuntary resettlement can not realize the objective of restoring and improving resettlers' living standard. With a view to improve this outcome, the concept of Resettlement with Development (RwD) was envisaged and is now generally heralded as the means to mitigate catastrophic failures of the past. However, few developing countries have included the concept of RwD into th, ational policies and China is one of them. The Chinese government has taken resettlement as an opportunity to help resettlers restore and improve their living standards and develop economy in reservoir areas by implementing RwD olicy including giving compensation and subsidies at early stage and offering production assistance at late stage, citing up reservoir construction fund, initiating partnership programs and preferential policy as well as enhanc infrastruture construction. The preliminary experience from the TGP resettlement has verified that the transformation from compensation-based resettlement to RwD is a right policy, choice. Meanwhile. because ofthe changing political environment and the complexity of involuntary resettlement there is still room for china to improve its RwD policy.  相似文献

Caves, Christensen and Diewert proposed a method for estimating a theoretical productivity index for a firm using Törnqvist input and output indexes, augmented by exogenous estimates of local returns to scale. However, in order to implement their method, they assumed that the firm maximized revenue in each period, conditional on the observed input vector in each period, taking output prices as fixed. This assumption is not warranted when there are increasing returns to scale. Thus in the present paper, it is assumed that the firm solves a monopolistic profit maximization problem when there are increasing returns to scale and the results of Caves, Christensen and Diewert are modified in accordance with this assumption.  相似文献

Can John Stuart Mill’s radicalism achieve liberal egalitarian ends? Joseph Persky’s The Political Economy of Progress is a provocative and compelling discussion of Mill’s economic thought. It is also a defense of radical political economy. Providing valuable historical context, Persky traces Mill’s intellectual journey as an outspoken proponent of laissez-faire to a cautious supporter of co-operative socialism. I propose two problems with Persky’s optimistic take on radical social reform. First, demands for substantive equality have led past radicals to endorse exclusionary nationalist and eugenics policies. It pushes some contemporary radicals towards illiberal interventions into intimate social life. Second, the radical critique of capitalism relies on an account of profit that neglects the epistemic function of private-property markets. Once this is acknowledged, capitalism retains some progressive credentials against radical alternatives.  相似文献
