Materials and methods: a sys...

Based on a contingent valuation method survey on air quality improvement in northern China, we construct several subjective perception determinants of respondents' valuation uncertainty from both the demand and perceived supply sides. Using the individual-level uncertainty measurements initially proposed by Wang and He (2011) and their alternative...

Background Because health resources are limited, health programs should be compared to allow the most efficient ones to emerge. To that aim, health utility instruments have been developed to allow the calculation of quality-adjusted life-year (QALY). However, generic instruments, which can be used by any individual regardless of their health profil...

Background The value of a Quality-Adjusted Life-Year (QALY) is of great importance for the healthcare system. It helps when it comes to defining a cost-effectiveness threshold for the evaluation of health technologies. No willingness-to-pay value for a QALY exists in the province of Quebec, Canada. Objectives In this paper, we empirically investig...

Les mesures de quarantaine et de confinement misent en oeuvre pour lutter contre la propagation de la COVID-19 ont potentiellement des effets négatifs sur la qualité de vie reliée à la santé (QVRS). Certains groupes de population sont cependant plus à risque que d'autres de connaître une dégradation de leur QVRS. L'objet de cette étude est de mesur...

Payments for ecosystem services (PES) programs in agriculture are designed to encourage farmers to adopt agro-environmental practices through financial or non-financial incentives. Using a choice-based conjoint (CBC) analysis, we measured public preferences regarding different constitutive attributes of PES (e.g., types of agro-environmental measur...

In this study we examine whether and why preferences for environmental quality improvements depend on current quality. We conducted contingent valuation surveys over the course of a year in Nanjing, China, and find that the willingness to pay for future air quality improvements increases by 0.693% for every 1% increase in the current PM2.5 level. T...

The lack of information on the value of ecosystems contributing to human well-being in urban and peri-urban setting is known to contribute to the degradation of natural capital and ecosystem services (ES). The purpose of this study was to determine the economic value of ES in Canada’s Capital Region (Ottawa-Gatineau region), so that these values ca...

We conducted a field stated preferences survey to understand the influence of payment and provision consequentiality script on valuation associated with voluntary contribution. Based on four treatment groups with single or combined consequentiality scripts and a contingent-ranking willingness to pay question, this paper provided some evidence that...

Background: In Canada, 11.5% to 15.7% of couples suffer from infertility. Anovulation, or failed ovulation, is one of the main causes of infertility in women. In Quebec, the treatment for ovulation induction and other services related to assisted reproductive technology (ART) have been partially reimbursed by the government since 2010. Objective: T...

Economic valuation can be biased by public distrust in local institutions when those institutions are involved in the valuation scenario design, which is often the case for contingent valuation (CV) studies. To better identify and to calibrate the potential biases, we conduct two CV surveys on people's willingness to pay (WTP) for the implementatio...

The cornerstone of China's strategy for developing high-technology activities is construction of scientific parks to create conditions emulating the successful High-technology clusters in the West. This is a comparative case study of biotechnology clusters in Guangdong province and the better documented ones in Beijing and Shanghai and Shenzhen. Th...

Obesity is a major public health problem because of its high prevalence and its association with many chronic diseases. The purpose of this study is to evaluate the willingness to pay (WTP) for the implementation of an integrated obesity management program including training and e-learning in Family Medicine Groups (FMGs) in order to improve the ma...

Based on a case study carried out on the Lac Saint-Pierre (LSP) World Biosphere Reserve (Québec, Canada), this paper estimates ecosystem service loss, more precisely the loss related to cultural and recreational activities of the LSP due to the fall of its water level under the pressure of climate change. We measure two dimensions of this loss. As...

Algal blooms, whether they are harmful or more akin to a nuisance, do pose negative impacts on human wellbeing. In the province of Quebec, excessive phosphorus that contributes to the problem of cyanobacterial blooms comes mainly from non-point sources. Limited regulation on the management of this nutrient leads to its strong accumulation in soils...

Orthopedics is a discipline that requires a continuum of care in close collaboration with physicians, nurses, and healthcare professionals to ensure effective rehabilitation. In some cases, the wait time for a consultation may be very long, which can jeopardize the patient’s rehabilitation and sometimes even cause complications that lead to a loss...

Nous calculons la balance des emissions de carbone incorporees au commerce (BEIC) bilateral franco-chinois entre 1996 et 2005. Les resultats confirment le role d’exportateur net en carbone de la Chine et l’augmentation rapide de l’excedent de la BEIC depuis l’adhesion de la Chine a l’Organisation mondiale du commerce. Cependant, la quasi-totalite d...

This study used a contingent choice method to determine the economic value of improving various ecosystem services (ESs) of the Blue Network of Greater Montreal (Quebec, Canada). Three real projects were used and the evaluation focused on six ESs that are related to freshwater aquatic ecosystems: biodiversity, water quality, carbon sequestration, r...

• La qualité et la quantité des services écosystémiques (SE) fournis par le lac Saint-Pierre (LSP), tels les produits de la pêche, les activités récréo-touristiques et la qualité des paysages, sont menacés par plusieurs facteurs de pression, dont les changements climatiques; • Selon plusieurs scénarios hydroclimatiques, les changements climatiques...

We examine how transboundary river pollution affects WTP for a river improvement project. The survey conducted in 20 cities of the Xijiang River basin demonstrates that downstream city report lowerWTPwhen its upstream is more polluted. This negative externality decreases with distance and relative bargaining power of downstream city. The simulated...

This article seeks to understand in the ways in which income inequality can affect children's health (z-score of stunting) in Guatemala. We postulate that there are several transmission channels through which income inequality can affect health and that the children's ethnic and rural origins influence the size and direction of this effect. The met...

Climate change will cause major changes in ecosystems. Therefore, it is crucial that climate change policy consider the value of all services that are provided by watershed ecosystems. For this purpose, geospatial data and economic analysis are combined to determine a monetary value for wetland ecosystem goods and services (EGSs) in the watersheds...

This article revisits the validity of the Environmental Kuznets Curve hypothesis. Based on data for seven pollutants in 29 Chinese provinces from 1995 to 2010, we conducted statistical tests on the coefficients of the critical variables (polynomial income-related terms) by following the logic of a “General Sensitivity Test,” more often known under...

Objective To measure the willingness to pay (WTP) of women aged 18–45 years to receive drug treatment for ovulation induction (ie, the social value of normal cycles of ovulation for a woman of childbearing age) in order to feed the debate about the funding of fertility cares. Setting An anonymous questionnaire was used over the general population...

Municipal solid waste management (SWM) is a major challenge for local governments in rural China. One key issue is the low priority assigned by the local government which is faced with limited financing capacity. We conducted an economic analysis in Eryuan, a poor county in Yunnan, China, where the willingness- to- pay (WTP) for an improved solid w...

In this paper, we use a 16 manufacturing-sector single-country linked input–output model to calculate the balance of emissions (carbon) embodied in trade (BEET) and pollution terms of trade (PTT) for China's international trade with the entire world and with its principal trade partners (Japan, the US, and the European Union) for the period from 19...

This paper presents a study of the willingness-to-pay (WTP) for surface water quality improvement in China. In the Huaping County of Yunnan Province, we found that people are willing to pay 74 Yuan (or US$12.33 in 2012 prices) per household per month (or 5% of household income) continuously for five years to achieve an improvement of water quality...

In this paper, we construct a model in which the impact of pollution on health is exerted through both direct and indirect channels. The indirect channel is captured by a production function in which the principal health-improving factor, income growth, can be realized only in the cost of pollution increase. This model is then tested by the aggrega...

In this paper, we analyzed data addressing people's perceptions of the importance of selection criteria for vehicle-related emissions control policies and measures based on a three-round survey organized during three professional air quality control international conferences in 2006 through 2010 based on the Delphi survey approach. More than 300 pa...

With the propensity score matching method, we carried out an average benefit incidence analysis that helps disclose those who really benefited from the sanitary services in Guatemala. Specifically, we tested the role of income, maternal education and social capital on how sanitary infrastructures affect child health. Results indicated that the chil...

In many cases, the relationship between environmental pollution and economic development can be generally depicted by an inverted U-shaped curve, or an environmental Kuznets curve, where pollution increases with income at the beginning and decreases after a certain level of income. However, what determine the shape of an enviornmental Kuznets curve...

Municipal solid waste management continues to be a major challenge for local governments in both urban and rural areas across the world, and one of the key issues is their financial constraints. Recently an economic analysis was conducted in Eryuan, a poor county located in Yunnan Province of China, where willingness to pay for an improved solid wa...

Les auteurs ont mené une étude sur le coût des techniques opératoires pour le traitement des petites tumeurs rénales, comparant les techniques standard de chirurgie ouverte et laparoscopique et la nouvelle technologie de cryoablation.

New designs of care in orthopaedic clinics are needed to cope with the shortage of orthopaedic surgeons and the lengthening of waiting times. To assess the effectiveness of an interdisciplinary orthopaedic clinic with a pivot nurse in the Canadian province of Quebec with regard to accessibility, quality of care, efficacy and efficiency of the clini...

According to the environmental Kuznets curve hypothesis, the relationship between per-capita GDP and per-capita pollutant emissions has an inverted-U shape. This implies that, past a certain point, economic growth may actually be profitable for environmental quality. Most studies on this subject are based on estimating fully parametric quadratic or...

Having observed the weaknesses in previous structural analyses on the role of Environmental Kuznets Curve (EKC), the author proposes a detailed analysis using a rich data set of provincial level production and SO2 emission intensity of 13 industrial sectors. The latter represent more than 98% of the total industrial production in each Chinese provi...

This article presents a new modelling strategy that estimates individual valuation distributions with Multiple Bounded Discrete Choice (MBDC) data. An individual's valuation of a commodity or service is assumed to have a distribution rather than being a single number. Likelihood responses to the MBDC questions are numerically coded and treated with...

Economic analyses of development projects and policies often involve assigning an economic value to changes in the risk of loss of human life. A typical term used in the economic analyses is the value of statistical life, which reflects the aggregation of individuals'willingness to pay for fatal risk reduction and therefore the economic value to so...

Nous utilisons un modèle LSTVAR (Logistic Smooth transition Vector Auto Regression) pour questionner la présence d’une relation asymétrique entre la variation du prix du pétrole et les rendements de l’indice SP 500. Les tests statistiques nous ont confortés dans l’utilisation du modèle à transition graduelle entre les états, confirmant l’hypothèse...

L’intensité de pollution inférieure des firmes de grande taille et leurs moindres coûts marginaux de réduction des émissions demeurent un fait largement documenté dans la littérature empirique. En poursuivant les intuitions de Merlevede et al (2006), nous examinons l’hypothèse qu’avec l’accroissement du développement économique, la présence de firm...

This paper seeks to understand in which ways income inequality can act on children’ health in Guatemala. We postulate that there are several transmission channels of income inequality on health and that the ethnic and/or rural origin of the children can have an influence on the size and the direction of this effect. Methodology used is systems of s...

This paper discusses the validity of the Environmental Kuznets Curve (EKC) hypothesis for the case of China's industrial SO2 emissions: both its reduced form and structural model are considered. The EKC curve for China's per capita industrial SO2 emissions predicts the turning point at 10,000 yuan (3,085 US$, Purchasing Power Parity (PPP)). However...

L’estimation des coûts liés à l’imposition de limites aux émissions de gaz à effet de serre (GES) a fait l’objet de beaucoup d’attention médiatique dernièrement. La Chine étant un des plus grands émetteurs de GES, l’évaluation des coûts pour l’économie chinoise est donc primordiale. Dans ce travail, nous évaluons le coût de l’imposition d’une taxe...

In order to gain deeper insight into the impacts of FDI on the air pollution situation in Chinese cities, I construct a simultaneous system. This system supposes the air pollution indicators to be determined by economic scale, industrial composition and technical characters of a city and in turn, FDI entry can affect the production scale, structure...

To get better understanding on trade’s impact on environment, we construct a four-equation simultaneous system, in which emission is determined by the three economic determinants: scale, composition and technical effects and directly by trade. Supposing the three economic determinants are also endogenous to trade, we check in the following three fu...

We develop two public choice models in which environmental regulation is determined endogenously in the presence of agents who are heterogenous in wealth or income. In the first model, regulation is determined by a majority vote, and an increase in inequality induces an increase in environmental standard. In the second model, the environmental stan...

This paper surveys the existing Environmental Kuznets Curve studies and discusses to what extent they may be valid and applicable for developing countries. We found that, given the shortcomings in both the theoretical and empirical aspects of the analyses applied to this hypothesis, no one-fit-for-all inverted-U-shaped curve can describe adequately...

Recognizing the complex inter-correlation between FDI, emission and the three economic determinants of emission, we constructed a simultaneous model to study the FDI–emission nexus in China by exploring both the dynamic recursive FDI entry decision and the linkage from FDI entry to final emission results under the intermediation of the scale, compo...

This paper discusses the validity of the Environmental Kuznets Curve hypothesis for the case of China’s industrial SO2 emission through both reduced and structural model. The estimated Chinaspecific EKC curve for per capital industrial SO2 emission predicts the turning point of 9000 yuan (2750 USD, PPP). However, given China’s fast population expan...

Observing the weakness in the previous structural analyses on Environmental Kuznets Curve (EKC) formation, in this paper, author deepens the analysis into the detailed data of production and SO2 emission intensity of the 29 industrial sectors (occupying over 98% of the total industrial production) in each Chinese province during 1991-2001. With the...

To understand the potential impacts of China's accession to WTO on her new desulphur policy (gradual reduction of 10% of annual SO2 emission by 2005 with respect to that of 2000), we construct a CGE model in which SO2 emission is directly linked to energy input consumption in production. The model equally considers the substitution possibility betw...

China realized during the last 15 years spectacular economic growth success. However, its economic growth was also accompanied by serious environmental degradation problems. China has been ranked as one of the most polluted countries in the world by some international organizations, particularly on the aspect of air pollution. Although many scholar...

In this paper, basing on panel data on Chinese provincial level from 1991-2000, we test, firstly, the existence of EKC for industrial SO2 emission density. Following, we decompose the economical determinants of this SO2 emission density into: income effect (GDPPC), scale effect (Industrial GDP per km2) and composition effect (industrial capitalisti...

This paper uses a dynamic CGE model, calibrated to new and detailed Chinese emissions data, to assess two important questions. What can we reasonably expect Chinese emissions trends to look like over the next two decades? Secondly, what would be the appropriate policy interventions to flatten Chinese emissions trajectories and reduce the risk of lo...

To understand the potential impacts of China’s accession to WTO in her new de-sulphur policy (reduction of 10% of SO2 emission in 2005 with respect to that of 2000), we construct a CGE model in which the SO2 emission is linked directly to energy intermediary consumption in production. The positive externality of trade on China’s economy is also inc...

This paper uses a dynamic CGE model, calibrated to detailed Chinese emissions data, to assess two important questions. What can we reasonably expect Chinese emissions trends to look like over the next three decades? Secondly, what would be the appropriate policy interventions to flatten Chinese emissions trajectories and reduce the risk of local, r...

Based on single-country linked Input-Output model, this paper first calculated the balance of emission embodied in trade (BEET) and pollution trade terms (PTT) for China’s international trade during 1996-2004. Our results confirm China as a net emission exporter but also find China’s exports to be less-polluting than China’s import. Our estimation...
