Smoking Restrictions as a Self-Control Mechanism

Using data from Current Population Survey Tobacco Use Supplements spanning 1992–2002, this study shows that smokers who plan to quit smoking are more supportive of regulations than are other smokers. Failed quitters who plan to try again are more supportive of restrictions than are smokers planning to quit for the first time. These findings indicate that many smokers support regulatory restrictions to reduce their costs of quitting by exploiting the discipline offered by regulatory control. From 1992 to 2002, support for smoking restrictions in public areas rose dramatically among both nonsmokers and smokers.JEL Classification: I180, I120, H000     

辽宁省交通运输业与经济增长关系的实证分析

交通运输业的发展水平与国民经济增长的适应程度可以通过建立“推动效应”模型和“拉动效应”模型的方法进行具体测算。经实证分析,辽宁省交通运输业的发展水平已经成为辽宁区域经济快速增长的“瓶颈”,特别是铁路运输业的发展更是严重滞后于辽宁省GDP的增长。辽宁省应该从资金、技术和结构三个方面来改善交通运输业的发展状况。

Longitudinal predictors of cigarette use among students from 24 Texas colleges

ABSTRACT

Objective: The purpose of this study is to examine differences between current and non-current cigarette users, focusing on sociodemographic factors, non-cigarette tobacco product use, parental and friend use, and alcohol and marijuana use; and to identify predictors of cigarette use sixmonths later. Participants: Participants included young adults (n = 4,296) from 24 Texas colleges, participating in a young adult cohort study, beginning in fall 2014. Methods: Mixed effects logistic regressions were conducted accounting for school-level variability. Results: Cigarette users were older, more likely to report use of non-cigarette tobacco products and peer use of cigarettes than non-current users. Wave 1 cigarette and non-cigarette tobacco product use, marijuana use and binge drinking, and peer use all uniquely predicted cigarette use at wave 2. Conclusions: Colleges need prevention programs targeting multiple tobacco products, because non-cigarette tobacco use and other risky behaviors appear to be independent risk factors for cigarette use in young adults.

Are there interregional differences in the response of cigarette smoking to state cigarette excise taxes in the USA? Exploratory analysis

Within the context of the period fixed-effects model, this study uses a 2002–2009 state-level panel data set of the USA to investigate the relative impact of state cigarette excise taxation across the nation in reducing cigarette smoking. In particular, by focusing upon the state cigarette excise taxation levels within each of the nine US Census Divisions, this study investigates whether there are inter-regional differences in the rate of responsiveness of cigarette consumption to increased state cigarette taxes. The initial empirical estimates reveal that although the per capita number of packs of cigarettes smoked annually is a decreasing function of the state cigarette excise tax in all nine Census Regions, the relative response of cigarette smoking to state cigarette tax increases varies considerably from one region to the next. Reinforcing this conclusion, in one specification of the model, the number of packs of cigarettes smoked in response to a higher state cigarette tax is statistically significant and negative in only eight of the nine Census Divisions. Furthermore, when cigarette smoking is measured in terms of the percentage of the population classified as smokers, interregional differentials in the response of smokers to higher state cigarette taxes are much greater. Thus, there is evidence that cigarette excise taxation exercises rather different impacts on the propensity to smoke across Census Regions.
