Happiness, geography and the environment

In recent years, economists have been using socio-economic and socio-demographic characteristics to explain self-reported individual happiness or satisfaction with life. Using Geographical Information Systems (GIS), we employ data disaggregated at the individual and local level to show that while these variables are important, consideration of amenities such as climate, environmental and urban conditions is critical when analyzing subjective well-being. Location-specific factors are shown to have a direct impact on life satisfaction. Most importantly, however, the explanatory power of our happiness function substantially increases when the spatial variables are included, highlighting the importance of the role of the spatial dimension in determining well-being.     

气候变化伦理研究评述

气候变化日益成为国际社会的一个热门话题。关于对气候变化问题的国际辩论经历了一个从科学、经济学和政治学争论到伦理争论的历程。气候变化是一个典型的＂全球伦理问题＂,气候变化伦理问题的关键是利益冲突。要解决＂缓解＂和＂适应＂气候变化、碳排量分配的合理性、发展中国家的发展空间及其补偿等一系列问题,必须要对气候公正原则、共同而有区别的责任等问题获得共识。     

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.     

The impact of climate change skepticism on adaptation in a market economy

Climate change will increase the risk of temperature extremes. Induced innovation could offset some of this threat. This paper explores the demand and supply for climate adaptation innovation in a market economy. Such innovation attenuates the past relationship between the population death rate and extreme heat. Climate change induces this innovation because the rising temperatures increase demand for self protection products and for profit firms respond to these incentives. We then augment the model to introduce “climate skeptics”. Such skeptics reject the claim that the world’s average temperature is rising and thus do not increasingly demand adaptation products. In an economy featuring no government to enact optimal taxation, we quantify how rational agents are affected by the presence of climate skeptics.     

GHG Targets as Insurance Against Catastrophic Climate Damages

The climate system is an angry beast and we are poking it with sticks 1 . A critical issue in climate change economics is the specification of the so‐called “damages function” and its interaction with the unknown uncertainty of catastrophic outcomes. This paper asks how much we might be misled by our economic assessment of climate change when we employ a conventional quadratic damages function and/or a thin‐tailed probability distribution for extreme temperatures. The paper gives some numerical examples of the indirect value of various greenhouse gas (GHG) concentration targets as insurance against catastrophic climate change temperatures and damages. These numerical exercises suggest that we might be underestimating considerably the welfare losses from uncertainty by using a quadratic damages function and/or a thin‐tailed temperature distribution. In these examples, the primary reason for keeping GHG levels down is to insure against high‐temperature catastrophic climate risks.     

Climate change and spatial agricultural development in Turkey

This paper investigates the impact of climate change on the spatial distribution of agricultural production in Turkey between 2004 and 2019. Our findings show that climate change has a pervasive impact on agricultural development. The empirical results show that the average temperature is negatively associated with agricultural land use, grain, and legume production. Moreover, regional variability analyses reveal the nonmonotonic relationships between climatic factors and agricultural output. Climate change hurts agricultural production in northern and central regions the most. This finding points out the ineffectiveness of one-size-fits-all-type policies for mitigating the adverse effects of climate change in topography with sizeable spatial dissimilarities. Overall, our results suggest that climate change will significantly threaten the evolution of agricultural activities that are critical for regional development. In addition, findings show that spatial spillovers and heterogeneity will be crucial for designing climate change policies for rural and agricultural development.     

International support of climate change policies in developing countries: Strategic, moral and fairness aspects

International transfers in climate policy channeled from the industrialized to the developing world either support the mitigation of climate change or the adaptation to global warming. From a purely allocative point of view, transfers supporting mitigation tend to be Pareto-improving whereas this is not very likely in the case of adaptation support. We illustrate this by regarding transfer schemes currently applied under the UN Framework Convention on Climate Change (UNFCCC) and the Kyoto framework.However, if we enrich the analysis by integrating distributional aspects, we find that international adaptation funding may help both the developing and developed world. Interestingly this is not due to altruistic incentives, but due to follow-up effects on international negotiations on climate change mitigation. We argue that the lack of fairness perceived by developing countries in the international climate policy arena can be reduced by the support of adaptation in these countries. As we show - taking into account different fairness concepts - this might raise the prospects of success in international negotiations on climate change. Yet, we find that the influence of transfers may induce different fairness effects on climate change mitigation negotiations to run counter.We discuss whether current transfer schemes under the UNFCCC and the Kyoto framework adequately serve the distributive and allocative objectives pursued in international climate policy.     

Transition welfare gaps: One closed,another to follow?

Respondents from post‐communist countries have been found to systematically report lower levels of happiness and self‐rated health. While the first welfare gap in happiness has closed recently, the second transition gap in self‐perceived health only started to close. Specifically, this paper shows that treating all transition countries as a homogeneous group may be misleading and therefore divides 28 transition countries into three groups. As a result, in the most recent 2016 round of the ‘Life in Transition’ survey, transition countries in Southern Europe are no longer found to be different from non‐transition nations in terms of their self‐rated health. Although the gap in self‐perceived health for transition nations in Eastern Europe is present in a basic model, it becomes less statistically and economically significant when subjective beliefs and macro‐level variables are added. Countries from the former Soviet Union and Mongolia remain the only group in which respondents report 16.5%–29.1% lower probability of ‘Good’ or ‘Very Good’ health compared to other transition and non‐transition countries. Controlling for communist party membership, ideological beliefs and macro‐level variables somewhat reduces the gap for the former Soviet Union and Mongolia but it remains significant in multiple robustness checks. Although the gap in self‐rated health now applies to only one group of transition countries, it remains an important empirical puzzle with far‐reaching implications for health policy, demand for healthcare and the process of transition.     

Investment climate,foreign networks and exporting – evidence from Africa

This paper investigates the impact of investment climate variables and foreign networks on the exporting decisions of African firms. We use data from the World Bank Investment Climate Surveys for over 7000 firms in 24 Sub-Saharan African countries. The results highlight the crucial role of the access to, and the quality of, investment climate characteristics – infrastructure, external finance and telecommunications for Sub-Saharan African firms’ exporting propensities. Our results show that improving the investment climate to the level of best performers in the sample will considerably increase the propensity of domestic firms to export. The paper also finds that foreign networks have a significantly positive impact on firms’ export propensities.     

TIME PREFERENCE, ABATEMENT COSTS, AND INTERNATIONAL CLIMATE POLICY: AN APPRAISAL OF IPCC 1995

This paper appraises current economic methodologies used in analyzing the social rate of time preference and discounting, abatement costs, and value of life estimates as they relate to climate change. It makes a case for choosing an appropriate rate of time preference when assessing climate policies, including both positive and normative considerations. Furthermore, the paper argues that the currently estimated disparity in the cost of greenhouse gas abatement between developed countries and developing countries may be inaccurate. Integrating discount rates, abatement costs, and value of life estimates highlights important and contrasting implications of international climate policy for developing and high-income countries. The context of the paper is the forthcoming Second Assessment Report of Working Group III of the Intergovernmental Panel on Climate Change.     

The amenity value of the climate: the household production function approach

A basic assumption of the hedonic technique is that there are no barriers to mobility that prevent prices changing to reflect the net benefits of a given location. But climate variables are undeviating over relatively large distances and the absence of a common language coupled with the existence of political boundaries may prevent the net advantages associated with a particular region from being eliminated. Apart from in a handful of countries, methods alternative to the hedonic approach may therefore be required to estimate the amenity value of climate. Adopting the household production function approach this paper undertakes a systematic examination of the role played by climate in determining consumption patters using data from 88 different countries. Given certain assumptions the paper then proceeds to calculate the constant utility change in the cost of living for a 2.5 °C increase in globally averaged mean temperature. It is determined that high latitude countries benefit from limited climate change whereas low latitude countries suffer significant losses.     

美国应对全球气候变化的科技计划

2002年2月，美国总统布什改组了美国应对全球气候变化的领导机构，以协调和指导美国应对全球气候变化的科技活动。在新的领导体制下，美国气候变化科学研究和与气候相关的技术开发项目集成到了一个前所未有的程度，形成了相互关联的两大科技计划，即气候变化科学计划（CCSP）和气候变化技术计划（CCTP），并设立了相应的气候变化科技计划管理机构。 本文对上述两大计划，以及美国未来应对全球气候变化、减少温室气体排放的近期和中长期技术选择进行了调研，供参考。     

Multi-level Governance and Global Climate Change in East Asia

Climate change is an issue that requires integrated action at multiple levels of government and within the spheres of politics, economics, and society. National, regional, and local governments have both distinct and complementary roles in developing climate mitigation and adaptation strategies. Compared with the attention that has been given to international and national activities in East Asia, relatively limited attention has been paid to the role of urban and regional governments in combating global climate change. Cities and provinces are initiating their own climate action plans, positioning themselves as environmental model cities, and joining local, national, and international networks for climate change. This article examines urban and prefectural climate policies in China, Japan, and South Korea within a multilevel governance framework.     

Getting the Resilience Right: Climate Change and Development Policy in the ‘African Age’

ABSTRACT

Founded on a call to place climate change adaptation and climate risk management at the heart of contemporary development practice, the World Bank’s Africa Climate Business Plan presents an ambitious agenda for coordinating $19bn of loans, grants and investment over the coming decade. The centrepiece of this recasting of development thinking is the notion of resilience, which ties together the various activities proposed under the Plan. Resilience must respectively be strengthened, empowered and enabled in order for African countries to withstand climate change impacts. In this paper we subject this new climate-resilient development discourse to critical scrutiny. Using the theoretical lens of post-politics, we caution how the ill-defined category of resilience is deployed to reinforce a profoundly depoliticising agenda in which climate change is posited as an external threat to an otherwise seamless narrative of African advancement. In so doing, we illustrate how the Bank obscures the contested histories of African development and uses the discourse of climate-resilient development to perpetuate its neoliberal agenda within the continent.     

Climate change as a threat to biodiversity: An application of the DPSIR approach

Climate change and its consequences present one of the most important threats to biodiversity and the functions of ecosystems. The stress on biodiversity is far beyond the levels imposed by the natural global climatic changes occurring in the recent evolutionary past. It includes temperature increases, shifts of climate zones, melting of snow and ice, sea level rise, droughts, floods, and other extreme weather events. Natural systems are vulnerable to such changes due to their limited adaptive capacity. Based on an analysis using the DPSIR framework, this paper discusses some of the important socio-economic driving forces of climate change, with a focus on energy use and transportation. The paper also analyses observed and potential changes of climate and the pressures they exert on biodiversity, the changes in biodiversity, the resulting impacts on ecosystem functions, and possible policy responses. The latter can be divided into mitigation and adaptation measures. Both strategies are needed, mitigation in order to stabilise the greenhouse gas concentrations in the atmosphere, and adaptation in order to adjust to changes that have already occurred or cannot be avoided. One mitigation option, increased biofuel production, which is also a response to oil depletion, would change land use patterns and increase human appropriation of net primary production of biomass, thereby threatening biodiversity. By considering the first order and second order impacts of climate change on biodiversity when developing policy measures, it will be possible to integrate ecosystem and biodiversity protection into decision-making processes.     

Cooperatives and happiness. Cross-country evidence on the role of relational capital

Why is the share of happy people higher in some countries than in their equally developed neighbours? We conjecture that the apparent contradiction might depend on a country’s endowment of relational capital, which we proxy empirically with the extent of cooperativeness. In particular, within the black box of social capital, we consider relational capital as the outcome of the civil economy paradigm and use cooperativeness as the macro and objective proxy of long term face-to-face interaction. Compiling an index of the importance of the cooperative sector, we test whether more cooperativeness associates with more happiness controlling for countries’ HDI and other control variables. Checking for endogeneity, using various country samples, and through different regression methods we find support for our hypothesis. This suggests that, indeed, an institutionalized cooperative culture can promote happiness.     

What’s at Stake in Securitising Climate Change? Towards a Differentiated Approach

Climate change has been successfully represented as a security concern to such an extent that it is firmly established on the political agenda, even though the implementation of concrete policies is disputed. In this paper, we develop an analytical framework to better trace the process of securitising climate change and assess its normative implications. We establish a typology of six climate security discourses on the basis of two dimensions: three levels of referent objects and two logics of securitisation, one that corresponds to the original Copenhagen School framework and one where the threat takes the form of the invocation of risk. We find that there are significant differences in the relative importance of the resulting climate security discourses in Germany and the US, but that normatively, all discourses come with their own problems, which calls for more detailed scrutiny and assessment of climate security discourses and their political effects.     

The curse of natural resources

This paper summarizes and extends previous research that has shown evidence of a “curse of natural resources” – countries with great natural resource wealth tend nevertheless to grow more slowly than resource-poor countries. This result is not easily explained by other variables, or by alternative ways to measure resource abundance. This paper shows that there is little direct evidence that omitted geographical or climate variables explain the curse, or that there is a bias resulting from some other unobserved growth deterrent. Resource-abundant countries tended to be high-price economies and, perhaps as a consequence, these countries tended to miss-out on export-led growth.     

Does Off-Farm Wage Employment Make Women in Rural Senegal Happy?

This paper investigates the impact of wage employment on women’s well-being in the Senegalese horticultural export industry. It uses a subjective well-being approach, based on self-reported happiness, to capture income and non-income aspects of employment. The study uses original survey data from 2013 for the Saint-Louis region in Senegal and an instrumental variable approach, supported by information from focus group discussions. It finds that women’s employment improves subjective well-being for the poorest women, but not for women whose household income is above the poverty threshold. Women’s employment improves women’s happiness through an income effect, as it leads to higher income levels and improved living standards, but the non-income effects reduce women’s happiness. This negative effect is related to a higher workload and low job satisfaction due to unfulfilled expectations. The positive income effect outweighs these negative non-income effects for poor women but not for relatively wealthier women.     

The effects of climatic variation on rice production in Sri Lanka

We study the responsiveness of rice production to climatic variation using a recent pseudo-panel data set from Sri Lanka. Output per farm is modelled as a non-linear function of temperature and rainfall (and other standard controls) using fixed effects regressions. We find that both climatic variables have concave, non-monotonic effects upon production, and that output is close to maximized at current climatic values. This implies that variations in growing conditions are likely to have negative effects upon production. Random simulations are used to model these impacts under various climate change scenarios, and we find that increasing temperatures will adversely affect rice production much more than varying rainfall, although the effects of a small ceteris paribus rise in temperature are positive. As rice production is a key component in economic output for Sri Lanka and other developing countries, our results have implications for food policy and poverty management in the future.
