气候变化视角下发展低碳经济的探析

应对气候变化是指人类社会、生产活动适应气候变化,减少温室气体排放所采取的措施.低碳经济是在应对气候变化背景下实现可持续发展的经济增长模式.随着我国国民经济持续快速发展,能源消费随之快速增长,能源供需缺口也在逐年拉大;同时我国能源消费仍以煤炭为主,导致碳排放总量急剧上升.针对此现状,我们应当从增加清洁能源比重、加大节能减排力度等方面控制碳排放量上升,走发展低碳经济的道路.     

The impact from changes in stock market valuations on investment: new economy versus old economy

This paper investigates whether there is a different impact from changes in ‘new’ and ‘old’ economy stock valuations on private investment for seven OECD economies. A vector autoregressive model is estimated for each individual country, using quarterly data over the period 1990–2000. It is found that the impact from changes in valuations of new economy stocks to investment is roughly the same in North America and in the United Kingdom as in continental Europe. By contrast, the impact from changes in old economy stock valuations on investment is, in general, larger in North America and in the United Kingdom than in continental Europe. Finally, the results suggest that in continental Europe the impact on investment from changes in the valuation of new economy stocks is bigger than for old economy stocks, whereas for North America and the United Kingdom, the impact is more similar.     

Identification of national priority areas for adaptation to climate change in China

The problem of global warming has been identified as the first in the list of the top ten environmental problems in the world. As climate change will seriously affect the social and natural world that people live in, so it may lay serious repercussions on economic progress, social improvement, and sustainable development. International bodies everywhere and many of the countries＇ governments are responding urgently to this call In recent years, climate change has affected different regions in China in different ways. In its national agenda, the Chinese government should address the problem of climate change and its negative impact on socio-economic development. In this endeavor the nation should introduce policies which will help its people and economy to adapt to these effects and changes. Priority-fields of adaptation to climate change are the sensitive areas or departments which are more vulnerable to the negative influences of climate change. The negative impacts of climate change in some parts of China are considered to be very serious indeed as they affect the whole economy and community. As a result, priority should be given to these more affected regions for the limited state financing. This paper defines adaptation and discusses the basic principles and programs in the identi.fication of national priority areas where adaptation should be exercised. Based on the past studies, four priority areas in China are identified, namely, disaster prevention and mitigation, water resources, agriculture, and ecosystem. An analysis on the identification procedures, and the reasons and tasks involved are given for each.     

Political economy of climate change, ecological destruction and uneven development

The purpose of this paper is to analyze climate change and ecological destruction through the prism of the core general principles of political economy. The paper starts with the principle of historical specificity, and the various waves of climate change through successive cooler and warmer periods on planet Earth, including the most recent climate change escalation through the open circuit associated with the treadmill of production. Then we scrutinize the principle of contradiction associated with the disembedded economy, social costs, entropy and destructive creation. The principle of uneven development is then explored through core-periphery dynamics, ecologically unequal exchange, metabolic rift and asymmetric global (in)justice. The principles of circular and cumulative causation (CCC) and uncertainty are then related to climate change dynamics through non-linear transformations, complex interaction of dominant variables, and threshold effects. Climate change and ecological destruction are impacting on most areas, especially the periphery, earlier and more intensely than previously thought likely. A political economy approach to climate change is able to enrich the analysis of ecological economics and put many critical themes in a broad context.     

The impact of climate on life satisfaction

We analyse the influence of climate on average life satisfaction in 79 countries using data from the World Values Survey. Climate is described in terms of ‘degree-months’ calculated as the cumulated monthly deviations from a base temperature of 65 °F (18.3 °C). Our results suggest that countries with climates characterised by a large number of degree-months enjoy significantly lower levels of life satisfaction. This finding is robust to a wide variety of model specifications. Using our results to analyse a particular climate change scenario associated with the IPCC A2 emissions scenario points to major losses for African countries, but modest gains for Northern Europe.     

Countermeasures of adaptation to climate change： establishment and application for implementation matrix

In the conceptual framework of adaptation policy assessment to climate change, adaptation measures can be categorized as two groups：facilitation and implementation. Facilitation measures refers to activities that enhance adaptive capacity, while implementation refers to activities that actually avoid adverse climate impacts on a system by reducing its exposure or sensitivity to climatic hazards, or by moderating relevant non-climatic factors. This paper aims to establish a matrix of implementation measures of adaptation to climate change, through four different ways how adaptation can influencc the relevant elements of climate change. reducing the exposure, reducing the sensitivity, alleviating the adverse impacts and reducing the negative non-climatic factors, and then further discuss the particular implementation measures of adaptation to climate change, through application studies on the selected sub-systems, intend to organize the disordered implementation measures in existent, and put forward some new measures under the guidance of this matrix, which could enrich and promote the system and content of implementation measures of adaptation.     

Transition to a market type economy: The case of Czechoslovakia

Conclusion The privatisation and liberalisation steps referred to are an expression of the endeavour to accompany stabilisation efforts as quickly as feasible with the institutional and systemic changes as well as with policies for restructuring, to change the behaviour patterns of economics agents. Until this change takes place, the more effective the restrictive policies are in the financial sphere, the higher the costs incurred in the real sphere will tend to be.The achievement of the desirable trade-offs between the conflicting aims of the macroeconomic development is thus linked with the degree of success in the changes of behaviour of economic agents. The macroeconomic stabilisation will therefore in the longer run depend on the extent to which the regime actually changes, on the positive destabilisation of economic agents and on the progress in their restructuring.In Czechoslovakia there does not therefore seem to be as clear-cut a distinction, as in other reforming countries, between the phases of stabilisation policies, institutional and systemic changes and those of the restructuring policies.The measures to transform the Czechoslovak economy and the implementation of these measures represent an attempt to proceed on a wider front, to take coordinated steps in all the relevant spheres, implying a greater degree of simultaneity. This is a reflection of the strategy chosen which aims at a qualitative change to be accomplished rapidly, taking into account the fact that the individual steps in the various spheres of the transition process are closely interconnected. The approach followed could thus be considered a strategy to introduce groups of complementary policy measures, that is to say, to make several reform packages and to implement them sequentially.

The effect of ambiguous risk, and coordination on farmers' adaptation to climate change — A framed field experiment

The risk of losses of income and productive means due to adverse weather can differ significantly among farmers sharing a productive landscape, and is of course hard to estimate, or even “guesstimate” empirically. Moreover, the costs associated with investments in reduced vulnerability to climatic events are likely to exhibit economies of scope. We explore the implications of these characteristics on farmer's decisions to adapt to climate change using a framed field experiment applied to coffee farmers in Costa Rica. As expected, we find high levels of risk aversion, but even using that as a baseline, we further find that farmers behave even more cautiously when the setting is characterized by unknown or ambiguous risk (i.e. poor or non-reliable risk information). Secondly, we find that farmers, to a large extent, coordinated their decisions to secure a lower adaptation cost, and that communication among farmers strongly facilitated coordination.     

Long-term impact of trade liberalization on human capital formation

While a growing line of research has assessed the effect of trade liberalization on human capital formation, most of these studies focus on its short-term effect on individual’s school attendance. Much less is known about its long-run effect, as well as the impact on other aspects of human capital formation such as labor market and noncognitive outcomes. This paper studies the impact of trade liberalization on individuals’ long-term human capital accumulation, including school attendance, cognitive abilities, labor market performance, and noncognitive outcomes. By constructing prefecture-year-level tariff barriers, our identification strategy exploits variations in different cohorts’ exposure to a trade shock at age 16 for individuals within the same prefecture. Empirical results suggest that trade liberalization leads to decreased completed years of schooling, cognitive abilities, wage, and noncognitive outcomes. We provide suggestive evidence that this observed pattern is explained by the expansion of job opportunities in relatively low-skilled and labor-intensive sectors.     

Happiness convergence in transition countries

The “transition happiness gap” has been one of the most robust findings in the literature on life satisfaction. Until very recently, scholars using various datasets have shown that residents of post-communist countries were significantly less satisfied with their lives than their counterparts in non-transition countries (controlling for income and other socio-economic characteristics). The literature has explained this finding by the great macroeconomic instability of the 1990s, by a substantial decrease in the quality and accessibility of public goods, by the major increase in inequality, and by the rapid depreciation of pre-transition human capital. All these factors were expected to subside over time – at least after the post-Great-Recession recovery. In this paper, we consider two most recent datasets – the third wave of the Life in Transition Survey (administered in 2015–16) and the 2010–2016 waves of the annual Gallup World Poll. We find that by 2016 the transition happiness gap had closed. This convergence has taken place both due to a “happiness recovery” in post-communist countries after the Great Recession and due to a decrease in life satisfaction in comparator countries in recent years. We also find that the convergence in life satisfaction was primarily driven by middle-income young, educated individuals, regardless of gender.     

宏观经济景气波动对就业增长的影响

中国不成熟的市场经济和特殊的人口环境使得用就业弹性和奥肯定律均无法有效反映我国经济增长与就业关系,更无法刻画经济波动对就业的冲击。本文从宏观经济景气波动影响就业增长的三个路径：劳动力供给、劳动力需求和政府公共就业政策来建立系统的分析模型,以探析经济波动与就业增长的长期均衡关系和滞后冲击效应。在劳动力供给系统中,经济波动使经济活动人口增多,加快了就业增长;在劳动力需求系统中,经济波动不利于经济增长,从而不利于劳动力需求增长;在政府就业促进政策系统中,社会保障和就业的投入缓和了经济波动对就业增长的冲击。     

Public support for creating a market economy in Eastern Europe

Employing two large databases, we analyze the determinants of public support for the creation of a market economy in Eastern Europe. From a macroeconomic perspective inflation, unemployment, privatization, and enterprise restructuring reduce this support; alternatively, democratization, the creation of working financial markets, and foreign aid per capita increase support for the market. Across countries, higher inequality undermines market support. From a microeconomic perspective, labor market status, both the objective and the subjective economic situations of a person, political orientation, and the socio-demographic background of the respondent affect support for the market economy. For example, unemployed, relatively poor, older, female, and less-educated respondents living in rural areas are less inclined to favor the creation of a market economy.

Capital accumulation and real exchange rate behavior in a small open economy with credit market frictions

Summary. We consider the nature of the relationship between the real exchange rate and capital formation. We present a model of a small open economy that produces and consumes two goods, one tradable and one not. Domestic residents can borrow and lend abroad, and costly state verification (CSV) is a source of frictions in domestic credit markets. The real exchange rate matters for capital accumulation because it affects the␣potential for investors to provide internal finance, which mitigates the CSV problem. We demonstrate that the real exchange rate must monotonically approach its steady state level. However, capital accumulation need not be monotonic and real exchange rate appreciation can be associated with either a rising or a falling capital stock. The relationship between world financial market conditions and the real exchange rate is also investigated. Received: October 3, 1997; revised version: October 23, 1997     

The strong sequential core in a dynamic exchange economy

Summary. Dynamic exchange economies with uncertainty are considered where the information is released over infinite time. The strong sequential core of such an economy consists of those consumption streams that can be improved upon by no coalition at no moment of time. Non-emptiness of the strong sequential core is established given a high enough discount factor. Moreover, sufficient conditions are given under which the strong sequential core contains only time and history independent consumption streams.Received: 22 August 2002, Revised: 22 May 2003, JEL Classification Numbers: C71, C73, D51, D52.Correspondence to: P.
