CLEAN INDOOR AIR LAWS AND THE DEMAND FOR CIGARETTES 总被引:3,自引:0,他引:3
This paper empirically tests the effect of clean indoor air laws on smoking. Public place clean indoor air laws restrict cigarette smoking in public places such as restaurants. Private place clean air laws regulate smoking in private work places as well as in public places. This study uses a time series of cross sections of the 50 states of the United States and Washington, D.C., from 1975 through 1985, to estimate single equation and simultaneous equation models of cigarette demand. The single equation results indicate that both the public place law and the private work place law have a negative effect on cigarette demand. However, a test for endogeneity shows that the enactment of clean indoor air laws is a function of cigarette demand. Results from a simultaneous equations model indicate that the public place law has a significant negative impact on cigarette demand, while the work place law has no effect on cigarette demand. Although these results demonstrate that only states with low levels of smoking have passed work place clean air laws, the results do not imply that the level of smoking would not decrease if such a law were imposed in all states. 相似文献

In manufacturing industries, occupational health and safety measures ensure better working conditions for employees, which may influence their productivity. We study the impact of investments undertaken by small and medium enterprises in Vietnam in mitigating indoor pollution (including air quality improvements, heat and noise protection as well as lighting) on firm-level gross output and value added. We find that the amount invested by the firm in health has a significant positive effect on both outcomes. Given historically poor working conditions in Vietnam, policy implications relate to incentivizing and enabling firms to undertake such investments, on both moral and economic grounds. 相似文献

One of the major adaptation mechanisms to climate change is increased demand for cooling via the air conditioning of indoor environments. China's demand for air conditioners has displayed explosive growth since 1995. This paper provides estimates of the income and short run weather sensitivity of air conditioner adoption across urban areas for 29 Chinese provincial entities. We show that the adoption decision displays significant income and weather sensitivity in the short run, with adoption being higher the year following a hot summer. 相似文献

THE IMPACT OF PRICES AND CONTROL POLICIES ON CIGARETTE SMOKING AMONG COLLEGE STUDENTS 总被引:1,自引:0,他引:1
Smoking among youths and young adults rose throughout the 1990s. Numerous policies were enacted to try to reverse this trend. However, little is known about the impact these policies have on the smoking behavior of young adults. This article uses a dichotomous indicator of daily smoking participation in the past 30 days, an ordered measure representing the frequency of cigarette consumption, and a quasi-continuous measure of the number of cigarettes smoked per day on average to examine the impact of cigarette prices, clean indoor air laws, and campus-level smoking policies on the smoking behaviors of a 1997 cross section of college students. The results of the analysis indicate that higher cigarette prices are associated with lower smoking participation and lower levels of use among college student smokers. Local- and state-level clean indoor air restrictions have a cumulative impact on the level of smoking by current smokers. Complete smoking bans on college campuses are associated with lower levels of smoking among current smokers but have no significant impact on smoking participation. Bans on cigarette advertising on campus as well as bans on the sale of cigarettes on campus have no significant effect on the smoking behavior of college students. 相似文献

以长三角核心区域——太湖流域对研究对象,对其2014—2018年空气质量进行了时空异质性分析,并利用相关性分析探索了太湖流域空气质量驱动机制。结果表明:(1)太湖流域空气质量的总体空间差异较小,流域东部沿海沿江地区以及西南部山林区域的空气质量普遍较好。上海、嘉兴两市空气质量相对较好,无锡、镇江两市则较差,局部聚集性尚不明显;(2)自然生态空间、污染治理技术及协同治理对策可使城市在经济社会发展的同时实现空气质量的稳步改善。最后结合流域实际针对性提出了相适应的对策建议。 相似文献

This study analyses the health effects of modern heating, using China’s centralized home heating infrastructure as a natural experiment. The underlying health mechanism is that the recipients of modern heating do not need to rely on traditional fuels to heat their homes and thus suffer from less exposure to indoor air pollution. Furthermore, the improved quality of heating leads to health improvements. This article exploits spatial and time variation in the implementation of China’s centralized heating program, utilizing a difference-in-difference framework. Spatial variation takes the form of a discrete geographical cut-off between regions that receive centralized home heating and those that do not. Results show that areas with centralized heating have a 0.13% decrease in perinatal deaths and a decrease of 1.17% in the proportion of low-birth-weight infants. This translates into about 7000 fewer deaths and about 60,000 fewer low-birth-weight infants each year. Hence, there are enormous health benefits to the public provision of modern heat as a substitute for traditional heating methods, which are shown to be injurious to early-life health. These results strongly suggest that policymakers in developing countries should consider promoting cleaner heating methods. 相似文献

生态兴则文明兴,生态环境关系着生态文明体系的构建。2014年,我国设立第一批生态文明先行示范区,为生态文明建设在环境质量方面的成果评价提供了准自然实验环境。为了评价我国生态文明建设在空气质量改善方面的绩效,将江西、福建、贵州、云南和青海这5个省级生态文明先行示范区设定为处理组,运用合成控制法和DID模型对空气质量改善状况进行双重检验。结果表明:整体上,生态文明先行示范区建设对空气质量改善具有显著的效果;江西、贵州和云南的生态文明先行示范区建设均表现出对环境质量的改善作用,其中江西生态文明建设对空气质量改善成效尤为显著。因此,我国设立生态文明先行示范区对于空气质量改善具有显著效应,这对今后国家生态文明试验区建设尤其是在社会经济、资源环境等方面的协调发展具有重要的参考价值。 相似文献

We estimate the willingness to pay (WTP) of Beijing and Shanghai residents for improving the air quality of the two cities from their levels prior to the 2008 Beijing Olympic Games to the level achieved during the Olympics. The data are obtained from a contingent valuation study conducted through face-to-face interviews in June 2008 in Beijing and Shanghai prior to the Beijing Olympics, during which time there was intensive debate about Beijing's air quality. Residents in both cities are willing to pay more when they are more exposed to air pollution, when their disposable income increases, and when they have stronger beliefs that public opinion plays an important role in government policy making. Beijing residents are willing to pay more than Shanghai residents, due possibly to Beijing's poorer air quality. Overall, aggregate WTP for air quality improvement accounts for about 0.53% of the 2008 GDP in Beijing and 0.22% of the 2008 GDP in Shanghai. 相似文献
