Estimating worldwide life satisfaction

Whilst studies of life satisfaction are becoming more common-place, their global coverage is far from complete. This paper develops a new database of life satisfaction scores for 178 countries, bringing together subjective well-being data from four surveys and using stepwise regression to estimate scores for nations where no subjective data are available. In doing so, we explore various factors that predict between-nation variation in subjective life satisfaction, building on Vemuri and Costanza's (Vemuri, A.W., & Costanza, R., 2006. The role of human, social, built, and natural capital in explaining life satisfaction at the country level: toward a National Well-Being Index (NWI). Ecological Economics, 58:119-133.) four capitals model. The main regression model explains 76% of variation in existing subjective scores; importantly, this includes poorer nations that had proven problematic in Vemuri and Costanza's (Vemuri, A.W., & Costanza, R., 2006. The role of human, social, built, and natural capital in explaining life satisfaction at the country level: toward a National Well-Being Index (NWI). Ecological Economics, 58:119-133.) study. Natural, human and socio-political capitals are all found to be strong predictors of life satisfaction. Built capital, operationalised as GDP, did not enter our regression model, being overshadowed by the human capital and socio-political capital factors that it inter-correlates with. The final database presents a stop-gap resource that, until robust surveys are carried out worldwide, allows comparisons of subjective life satisfaction between nations to be made with reasonable confidence.     

Causal linkages between work and life satisfaction and their determinants in a structural VAR approach

Work and life satisfaction depend on a number of pecuniary and non-pecuniary factors at the workplace and determine these in turn. We analyze these causal linkages using a structural vector autoregression approach for a German sample of the working populace from 1984 to 2008, finding that workplace autonomy plays an important causal role in determining well-being.     

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.     

Valuing environmental factors in cost-benefit analysis using data envelopment analysis

Environmental cost-benefit analysis (ECBA) is used for the social evaluation of investment projects and policies that involve significant environmental impacts. Economic valuation of environmental impacts forms one of the critical steps of ECBA. We develop a new method for this purpose, which does not require price estimation for environmental impacts using stated or revealed preference methods. Our approach is based on data envelopment analysis (DEA), which is modified to ECBA by using absolute shadow prices instead of relative prices. We also discuss how the method can be used for sensitive analysis in ECBA. We illustrate the method by means of a hypothetical numerical example.     

Economic evaluation of rehabilitation: The quality of life approach using EuroQol

By using resources in a health care alternative activity, the objective for improved health requires the valuation of competing health care programs to inform resource allocation and facilitate prioritization. A measure of health status is used as an outcome of rehabilitation. This paper uses the EuroQol/EQ-5 as an instrument to measure health-related quality of life. Health status is used to determine values that correspond to preferences of the general public. This analysis assumes the existence of a structural problem where the performance of the rehabilitation program and the prognosis behind the definition of need for rehabilitation are determined simultaneously.     

Media use and life satisfaction: the moderating role of social events

This study investigates whether and how social events, which have specific impact levels and consequences, influence the relationships between the use of different types of media and media users’ life satisfaction. The impact levels refer to the number of impact factors, which characterize social events (relevance, non-polarization, certainty, radicalness and proximity). The consequences, in turn, refer to the outcomes for media users (positive or negative outcomes). The results are based on data from the Standard Eurobarometer survey (N = 73,860) as well as on data from a content analysis and cover 36 social events in 13 European countries over a time period of 6 years. The moderated moderation analysis reveals that social events only influence the effects of the use of more interactive media types (the internet and social network sites) on media users’ life satisfaction, but they don’t influence the effects of the use of less interactive media types (written press, radio and TV) on media users’ life satisfaction. In fact, social events with positive consequences increase these effects, while social events with negative consequences buffer these effects. Previous research has investigated how the use of different types of media or specific social events affect people’s life satisfaction. This study contributes to the literature by revealing how social events and media use interact and thereby influence media users’ life satisfaction.     

Valuing the social cost of corruption using subjective well being data and the technique of vignettes

Corruption can have an effect on people's happiness and satisfaction, and therefore, can generate a social cost. However, the perceptions of corruption and satisfaction can also vary across subjects, due to socioeconomic and cultural characteristics. This article studies the differences in the perceptions of corruption and satisfaction across subjects, utilizing the technique of vignettes for the correction of the bias that follows from the differences in the response scale across individuals. The evidence comes from a sample of citizens in Spain, who are asked about their perceptions of corruption and personal satisfaction. The results show that there exists a response scale bias, both for corruption and satisfaction. These results are utilized to approximate the social cost of corruption.     

The role of interviewer encounters in panel responses on life satisfaction

This note examines a common explanation why participants of panel surveys may report declining life satisfaction over time. In line with the argument of developing trust relationships between interviewers and interviewees, the analysis reveals positive effects in reported life satisfaction when the person conducting the interview changes to an unfamiliar individual. Yet, the evidence also shows that the overall decline is determined by years in the panel, rather than by number of encounters with one specific interviewer.

Valuing environmental and health risk in agriculture: A choice experiment approach to pesticides in Italy

The widespread use of pesticides in agriculture shows a complex ramification of multiple negative externalities, ranging from food safety-related effects to the deterioration of farmland ecosystems. Recent research has demonstrated that the assessment of the economic implications of such negative processes is fraught with many uncertainties. This paper presents the results of an empirical study recently conducted in Northern Italy aimed at estimating the economic value of reducing the wide-ranging impacts of pesticide use, by deploying a Choice Experiment approach. The experimental design provides a meaningful tool to assign monetary values to the negative environmental effects associated with agrochemicals use. In this connection, the paper addresses in particular the reduction of farmland biodiversity, groundwater contamination and harm to human health. The resulting estimates confirm that, on average, respondents demonstrate a substantial willingness-to-pay a premium for agricultural goods (in particular, foodstuffs) produced in environmentally-benign ways.     

Evaluating flood risk management options in Scotland: A participant-led multi-criteria approach

The characteristics of flood risk management include complexity, large spatial scales, inter-temporal issues, plural values and conflicts of interests. It is argued that issues with such characteristics require public participation in the decision making process. This study builds on existing deliberative processes to develop a new participant-led multi-criteria method to evaluate flood risk management options in Scotland. The results show that participants preferred regeneration or planting of native woodland to other flood management options, and least preferred building flood walls and embankments. The design of the workshops allowed a rich dataset to reveal the thinking behind such results and provided a deeper understanding of why participants came to these conclusions.     

The causal effect of income on life satisfaction and the implications for valuing non-market goods

Employing the life satisfaction approach to value physical health, this paper illustrates the use of a subset of windfall income (restricted windfall income) as a substitute for the more conventional household income monetary measure. Results provide no evidence against the exogeneity of restricted windfall income and indicate that the causal effect of income on life satisfaction is substantially higher (and willingness-to-pay estimates substantially lower) when restricted windfall income is used. Further research should be devoted to looking into the presence and size of measurement errors in restricted windfall income. If this bias is large, then the quest for valid and strong instruments will continue.     

Valuing the Arsenic Contamination of Groundwater in Bangladesh

The use of groundwater in Bangladesh has in the past been promoted as a means of avoiding waterborne diseases associated with the consumption of untreated surface water. Unfortunately, the recent discovery of high levels of naturally occurring arsenic in groundwater in Bangladesh used for drinking purposes has led one international agency to describe the situation as a major public health emergency. Arsenic ingestion is associated with an elevated risk of various cancers. Epidemiological dose–response functions combined with survey estimates of arsenic concentrations in groundwater, and the number of households in Bangladesh relying on groundwater for drinking are used to derive an estimate of annual mortality and morbidity cases attributable to arsenic contamination. The estimated health impacts include 6500 fatal cancers and 2000 non-fatal cancers. Aggregate willingness to pay to avoid these health impacts is estimated to be $2.7 billion annually using purchasing power parity exchange rates. The methodology and results presented in this paper may have application to other countries.     

Valuing the non-timber forest products in the Mediterranean region

The potential of non-timber forest products (NTFPs) in the Mediterranean region as a source of livelihood and sustainable development has been widely recognized. Yet, surprisingly few efforts have been made to value them comprehensively. Valuation efforts usually focused on selected NTFPs traded on formal markets, at local level. This paper aims to provide comprehensive estimates of NTFPs benefits at national and regional level in the Mediterranean region. Six major groups of NTFPs are identified: firewood, cork, fodder, mushrooms, honey and other NTFPs. Valuation is based on a wide variety of techniques, drawing on official statistics, and supplemented by results of local surveys. It shows that at Mediterranean level, NTFPs provide annual benefits of about €39/ha of forests, accounting for about a fourth of the total economic value of forests estimated by this study. The average estimate for southern countries (€54/ha) is considerably higher than for northern (€41/ha) and eastern countries (€20/ha). The paper reveals the degree of importance of the main NTFPs benefits for the country groups and the region as a whole. It also discusses some reasons of concern when drawing policy tools for improving rural income and forest conservation in the Mediterranean.     

Measuring the impact of natural disasters on capital markets: an empirical application using intervention analysis

The impact of natural disasters on the Australian equity market is examined. The data set employed consists of daily price and accumulation returns over the period 31 December 1982–1 January 2002 for the All Ordinaries Index (AOI) and a record of 42 severe storms, floods, cyclones, earthquakes and bushfires (wildfires) during this period with an insured loss in excess of A$5 mil. and/or total loss in excess of A$100 mil. Autoregressive moving average (ARMA) models are used to model the returns and the inclusion of news arrival, in the form of the natural disasters, is specified using intervention analysis. The results indicate that bushfires, cyclones and earthquakes have a major effect on market returns, unlike severe storms and floods. The net effects can be positive and/or negative with most effects being felt on the day of the event and with some adjustment in the days that follow.     

Valuing the Ozone-Related Health Benefits of Methane Emission Controls

Methane is a greenhouse gas that oxidizes to form ground-level ozone, itself a greenhouse gas and a health-harmful air pollutant. Reducing methane emissions will both slow anthropogenic climate change and reduce ozone-related mortality. We estimate the benefits of reducing methane emissions anywhere in the world for ozone-related premature mortality globally and for eight geographic regions. Our methods are consistent with those used by the US Government to estimate the social cost of carbon (SCC). We find that the global short- and long-term premature mortality benefits due to reduced ozone production from methane mitigation are (2011) $790 and $1775 per tonne methane, respectively. These correspond to approximately 70 and 150 % of the valuation of methane’s global climate impacts using the SCC after extrapolating from carbon dioxide to methane using global warming potential estimates. Results for monetized benefits are sensitive to a number of factors, particularly the choice of elasticity to income growth used when calculating the value of a statistical life. The benefits increase for emission years further in the future. Regionally, most of the global mortality benefits accrue in Asia, but 10 % accrue in the United States. This methodology can be used to assess the benefits of methane emission reductions anywhere in the world, including those achieved by national and multinational policies.     

Valuing water level changes in reservoirs using two stated preference approaches: An exploration of validity

The combination of travel cost (TCM) and contingent behaviour (CB) methods is a relatively new research avenue in the recreational valuation community. Contrary to simple TCM applications, TCM-CB facilitates the ex ante valuation of marginal welfare effects resulting from environmental quality or quantity changes, similar to the contingent valuation method (CV). Even though TCM-CB is highly policy relevant, i.e. to inform changes in management regimes at recreational sites, the validity of estimates has hardly received any attention and little is known about the performance of TCM-CB compared to CV. In this paper, TCM-CB and CV are explored with respect to several validity tests in a case study on the recreational effects of water level changes in a reservoir. Overall, the findings reveal that TCM-CB and CV perform equally well in terms of theoretical validity, but that the marginal recreational value varies significantly between the two methods. We also observe that both methods face similar internal difficulties with respect to the stability of values when the order of a set of valuation questions is changed.     

Making the risk of job loss a way of life: Does it affect job satisfaction?

This study investigates the relationship between job satisfaction and job security in European countries. In doing so, it attempts to take into account the endogenous nature of the job security–job satisfaction relationship after controlling for the various economic and personal characteristics. The results show that workers in jobs with low likelihood of job termination derive higher utility from work compared to the workers in insecure jobs. This holds even after controlling for endogeneity by using both a conventional IV approach and a selection model. This appears to be the case for both men and women.     

现代违约风险估值模型扩展前沿综述

一、引言违约风险一直是整个金融业面临的最主要的风险之一。长期以来,由于违约风险具有非对称性、非系统性、收益可偏性等特点,违约风险的研究和应用都集中在传统的专家系统法和基于财务报表的信用评分系统法。专家法多依赖于主观判断的定性分析,评价时易受感情和外界因素干扰,可能做出偏差较大。财务报表反映的是过去已发生的事项,对于市场尚未提供的信息,评价结果无法提供。近年来,随着资本市场的迅速发展、融资的非中介化、证券化趋势以及金融创新工具的大量涌现,违约风险的复杂性也日益显著。传统
