The Theory of Industrial Organization

Building on an idea in Abadie and Gardeazabal (2003), this article investigates the application of synthetic control methods to comparative case studies. We discuss the advantages of these methods and apply them to study the effects of Proposition 99, a large-scale tobacco control program that California implemented in 1988. We demonstrate that, following Proposition 99, tobacco consumption fell markedly in California relative to a comparable synthetic control region. We estimate that by the year 2000 annual per-capita cigarette sales in California were about 26 packs lower than what they would have been in the absence of Proposition 99. Using new inferential methods proposed in this article, we demonstrate the significance of our estimates. Given that many policy interventions and events of interest in social sciences take place at an aggregate level (countries, regions, cities, etc.) and affect a small number of aggregate units, the potential applicability of synthetic control methods to comparative cas...

Synthetic Control Methods for Comparative Case Studies: Estimating the Effect of California’s Tobacco Control Program

The aim of this updated statement is to provide comprehensive and timely evidence-based recommendations on the prevention of stroke among individuals who have not previously experienced a stroke or transient ischemic attack. Evidence-based recommendations are included for the control of risk factors, interventional approaches to atherosclerotic disease of the cervicocephalic circulation, and antithrombotic treatments for preventing thrombotic and thromboembolic stroke. Further recommendations are provided for genetic and pharmacogenetic testing and for the prevention of stroke in a variety of other specific circumstances, including sickle cell disease and patent foramen ovale.

Use of mass media campaigns to change health behaviour

This report builds on a highly valued predecessor, the 1994 Institute of Medicine (IOM) report entitled Reducing Risks for Mental Disorders: Frontiers for Preventive Intervention Research. That report provided the basis for understanding prevention science, elucidating its then-existing research base, and contemplating where it should go in the future. This report documents that an increasing number of mental, emotional, and behavioral problems in young people are in fact preventable. The proverbial ounce of prevention will indeed be worth a pound of cure: effectively applying the evidence-based prevention interventions at hand could potentially save billions of dollars in associated costs by avoiding or tempering these disorders in many individuals. Furthermore, devoting significantly greater resources to research on even more effective prevention and promotion efforts, and then reliably implementing the findings of such research, could substantially diminish the human and economic toll.

Preventing Mental, Emotional, and Behavioral Disorders Among Young People: Progress and Possibilities

Objectives. In early 2000, the American Legacy Foundation launched the national “truth” campaign, the first national antismoking campaign to discourage tobacco use among youths. We studied the impact of the campaign on national smoking rates among US youths (students in grades 8, 10, and 12).Methods. We used data from the Monitoring the Future survey in a pre/post quasi-experimental design to relate trends in youth smoking prevalence to varied doses of the “truth” campaign in a national sample of approximately 50000 students in grades 8, 10, and 12, surveyed each spring from 1997 through 2002.Results. Findings indicate that the campaign accounted for a significant portion of the recent decline in youth smoking prevalence. We found that smoking prevalence among all students declined from 25.3% to 18.0% between 1999 and 2002 and that the campaign accounted for approximately 22% of this decline.Conclusions. This study showed that the campaign was associated with substantial declines in youth smoking and has ...

Evidence of a dose-response relationship between "truth" antismoking ads and youth smoking prevalence

Objectives. This study examines how the American Legacy Foundation's “truth” campaign and Philip Morris's “Think. Don't Smoke” campaign have influenced youths' attitudes, beliefs, and intentions toward tobacco. Methods. We analyzed 2 telephone surveys of 12- to 17-year-olds with multivariate logistic regressions: a baseline survey conducted before the launch of “truth” and a second survey 10 months into the “truth” campaign. Results. Exposure to “truth” countermarketing advertisements was consistently associated with an increase in anti-tobacco attitudes and beliefs, whereas exposure to Philip Morris advertisements generally was not. In addition, those exposed to Philip Morris advertisements were more likely to be open to the idea of smoking. Conclusions. Whereas exposure to the “truth” campaign positively changed youths' attitudes toward tobacco, the Philip Morris campaign had a counterproductive influence. (Am J Public Health. 2002;92:901–907)

Getting to the Truth: Evaluating National Tobacco Countermarketing Campaigns

OBJECTIVE—To estimate the impact of workplace smoking restrictions on the prevalence and intensity of smoking among all indoor workers and various demographic and industry groups.
DESIGN—Detailed cross sectional data on worker self reported characteristics, smoking histories, and workplace smoking policies were used in multivariate statistical models to examine whether workplace smoking policies reduce cigarette consumption. After analysing the distribution of policies, four main types of workplace programme were defined: (1) 100% smoke-free environments, (2) work area bans in which smoking is allowed in some common areas, (3) bans in some but not all work and common areas, and (4) minimal or no restrictions.
SETTING—After environmental tobacco smoke was identified as a health hazard in the mid-1980s, workplace smoking restrictions became more prevalent. By 1993, nearly 82% of indoor workers faced some restriction on workplace smoking and 47% worked in 100% smoke-free environments.
PARTICIPANTS—The database included a nationally representative sample from the tobacco use supplements to the September 1992, January 1993, and May 1993 Current Population Surveys of 97 882 indoor workers who were not self employed.
MAIN OUTCOME MEASURES—Prevalence of smoking and number of cigarettes smoked daily by smokers.
RESULTS—Having a 100% smoke-free workplace reduced smoking prevalence by 6 percentage points and average daily consumption among smokers by 14% relative to workers subject to minimal or no restrictions. The impact of work area bans was lessened by allowing smoking in some common areas. Smoke-free policies reduced smoking for all demographic groups and in nearly all industries.
CONCLUSIONS—Requiring all workplaces to be smoke free would reduce smoking prevalence by 10%. Workplace bans have their greatest impact on groups with the highest rates of smoking.

The impact of workplace smoking bans: results from a national survey

In recent years there has been a heightened public concern over the potentially harmful effects of environmental tobacco smoke (ETS). In response, smoking has been banned on many jobs. Using data from the 1991 and 1993 National Health Interview Survey and smoking supplements to the September 1992 and May 1993 Current Population Survey, we investigate whether these workplace policies reduce smoking prevalence and smoking intensity among workers. Our estimates suggest that workplace bans reduce smoking prevalence by 5 percentage points and average daily consumption among smokers by 10 percent. The impact of the ban is greatest for those with longer work weeks. Although workers with better health habits are more likely to work at establishments with workplace smoking bans, estimates from bivariate probit and two-stage least square equations suggest that these estimates are not subject to an omitted variables bias. The rapid increase in workplace bans can explain all of the recent sharp fall in smoking among workers relative to non-workers.

Do Workplace Smoking Bans Reduce Smoking

Objectives. Reductions in exposure to environmental tobacco smoke have been shown to attenuate the risk of cardiovascular disease. We examined whether the 2003 implementation of a comprehensive smoking ban in New York State was associated with reduced hospital admissions for acute myocardial infarction and stroke, beyond the effect of moderate, local and statewide smoking restrictions, and independent of secular trends.

Methods. We analyzed trends in county-level, age-adjusted, monthly hospital admission rates for acute myocardial infarction and stroke from 1995 to 2004 to identify any association between admission rates and implementation of the smoking ban. We used regression models to adjust for the effects of pre-existing smoking restrictions, seasonal trends in admissions, differences across counties, and secular trends.

Results. In 2004, there were 3813 fewer hospital admissions for acute myocardial infarction than would have been expected in the absence of the comprehensive smoking ban. Direct health care cost savings of $56 million were realized in 2004. There was no reduction in the number of admissions for stroke.

Conclusions. Hospital admission rates for acute myocardial infarction were reduced by 8% as a result of a comprehensive smoking ban in New York State after we controlled for other relevant factors. Comprehensive smoking bans constitute a simple, effective intervention to substantially improve the public’s health.
