Drunk Driving the First Review: Eisenberg\'s Evaluation

Drunk Driving

The First Review: Eisenberg's Evaluation of policies' effectiveness in relation to drunk driving is the first policy review piece chosen for this article. In the research Eisenberg (2003) presented novel findings on the effectiveness of public policies on the state-level linked to drunk driving, effectiveness in this context refers to reduction in the number of fatal crashes. The author argues that endogenous policies lead to biased conventional estimates of policy effects. With respect to the date of adoption, the concern was addressed by the writer by examining the policy effects' time pattern. According to results, the 0.08BAC law has an upward bias, but the policy is still of use. This type of analysis also evaluated MADD (Mothers Against Drunk Driving) organization and graduated licensing programs for drivers of a younger age bracket. There is no effect implied according to the MADD estimates, this could be due to crude nature of the variable used. The policy has an effect as far as young drivers are concerned, but the time model estimates are overstated in conventional analyses for graduated licensing (Eisenberg, 2003).

The Second Review: The research paper, chosen as the second policy analysis, is by Carpenter and his assessment of the whether or not there is any effectiveness in the Zero Tolerance Drunk Driving Law. The first comprehensive analysis was provided in his paper on ZT Laws effects on an individual level based on; involvement in drinking that was self-reported, heavy periodic consumption of alcohol, previous month's consumption of drinks in number, and young adults who are involved in drunk driving. Particularly, Behavioural Risk Factor Surveillance System (BRFSS) was used by the research which is a vast source of micro data, from the year 1984 to 2001 and includes data on the drunk driving and alcohol usage behaviour for young individuals over the age of 18.

In the United States the figures on drunk driving are staggering. Over 42,000 lives have been claimed due to motor vehicle accidents in 2002 alone. The factor for 40% of these cases was alcohol. The statistics for the youth are even more alarming. Crashes that involved alcohol for below the age of 21 were nearly double than that of older individuals (Carpenter, 2004)

Educational programs, stringent penalties and laws, and college campus outreach linked to young individuals who drink and drive are the range of ways proposed by political analysts in response to the problem of drunk driving and underage driving. According to Zero Tolerance Laws, it is illegal for drivers to carry detectable levels of alcohol in the bloodstreams. The violation results in prompt suspension of license and monetary fines. The enacting of these laws began after 1983, and since that time, as a response to the federal compulsion and monetary incentives, all the fifty states and Columbia have introduced ZT jurisdictions. The research conducted regarding the effectiveness of such laws has increasingly showed their effectiveness. That is, Zero Tolerance Laws are correlated with reductions in highway accidents involving alcohol, for the concerned age bracket (Carpenter, 2004).

The foundation of Zero Tolerance Laws is the theory of broken windows. It is a criminology theory regarding the establishment of norms and indicating effect or riots and theft on additional crime and misbehaviours. According to the theory, keeping an eye on urban environments and maintaining them in a peaceful condition might impede additional vandalism and an increase into worse anti-social behaviour. Since the theory was introduced by George L. Kelling and James Q. Wilson, renowned social scientists, in a 1982 article, there has been great debate on it both in academic and public circles. Furthermore, it has also been used for many reforms in criminal laws as an incentive (Carpenter, 2004).

Although, ZT laws are generally believed to be effective, there is still debate going on what are the mechanisms through which they affect alcohol related highway fatalities. Although minorsmay adopt an attitude of restricting their alcohol usage, making it more moderate and/or driving less often at times when they are under the influence of alcohol, these laws may even increase the alcohol usage by underage individuals if they choose to substitute from driving to drinking alcohol indoors or utilize public transportation. Furthermore, all these variables are policy relevant: research has increasingly indicated that alcohol consumption might have a causal relationship with several undesirable outcomes for the young population. So, information about how much and what are the effects of alcohol driving policies on youth might be a source of information of several health laws (Carpenter, 2004).

The researcher has tried to measure the effects of Zero Tolerance Laws on drunk behaviours of 18- to 20-year-olds, restricting the macroeconomic environment, other alcohol-related laws, outline fixed effects, effects of the survey month and year, and linear state specific time trends. The standard difference-in-difference type method innate in the two-way fixed effects was supplemented by the identification of a controlled group of people who were otherwise like treated people but should have experienced the effects of Zero Tolerance laws. In short, a group of 22- to 24-year-olds in a difference-in-difference-in-differences (DDD) type framework were used for the purpose of comparing the group for alcohol induced treatment, 18- to 20-year-olds (Carpenter, 2004).

It was found that the overriding effect of such laws among the 18- to 20-year-old population was the reduction in extreme episodic drinking by around 13% which was accompanied by similar escalation in the chances of becoming a less-frequent drinker of alcohol and a decline in the overall drinks taken by the male youth. The highlighting results for male population are largely in affect by the addition of further repressors, which include state-specific linear time trends. Furthermore, in a DDD framework, the reduction in extreme occasional drinking are evident and consistent even when differences in age are sharp, that is, 20-year-old versus 22-year-olds. It was also found that the timing patterns of the decrease in extreme alcohol drinking were in line with the responses calculated using total overall fatality data (Carpenter, 2004).

The drinking behaviour of women falling in the age group of seniors is not controlled by the models furnished by the DD models. These models define the impact of ZT laws and intense occasional drinking as a major decrease is witnessed because of these laws. No decrement in the ratio of drinking or driving after being drunk was witnessed by the researcher, with respect to the policies designed to make it low (Carpenter, 2004).

According to the researcher, the disregarded cross state heterogeneity is specified by the models gauged by the researcher in order to determine the stage and tendency with respect to drinking. The models of highway traffic fatalities and usage of alcohol among young people have demonstrated biasness because of not taking the effects of year and unrestricted state into consideration, although this framework is being applied in the text of appraising policies and economics. Moreover, the controlling of month effects, year effects, state effects, and state trends have also demonstrated significant variation because of the policy (Carpenter, 2004).

With respect to the advances of this research as compared to the previous one, the sample size was 500% larger. It was 49000 young people. Because of having a sample size of significant number, the evaluation of ZT laws and its impacts was easier. It is necessary to evaluate these laws from time to time because it was implemented in most of the states between the years of 1995 to 2000. The observation till 2001 is included in BRFSS along with all the related information. Moreover, the related information regarding all the 50 states and District of Columbia is included in the current data. On the contrary, the previous researches only consist of pre and post comparisons using individual level data (Carpenter, 2004).

The subjects were used intimately by the researcher in age to the treatments as the age group of the samples in BRFSS was 18 plus, but the laws should not affect the subjects falling in the age group of 22 and 24, in order to net out disregarded shocks of year or state. Moreover, this research also included the demographic information, which was used in considering the subgroups affected by ZT laws, and in controlling the biasness in the estimator which was difference-in-difference in nature and regression adjusted. Besides, the body weight is also included in this research which will help in determining the level of ZT treatment (Carpenter, 2004).

Dummies are incorporated for study month in order to control seasonality which is very crucial empirically in the usage of alcohol. The inclusion of real date of interview in the research enabled the researcher replacing the usage of the common technique of allotting partial policy values for mid-year law adoption with the correspondence of a particular ZT policy in the result of every examination (as cited in Carpenter, 2004).

The ultimate objective after relating the minimum purchase age (MPA) laws and minimum legal drinking age (MLDA) laws with the typical ZT laws is whether it is applicable on the individual level data in order to observe the procedure behind the observed reduced form and deceased estimation. It was found that the deceases from drinking reduced due to the switching of alcohol users from intense occasional drinking to mild usage of alcohol, as demonstrated by the researcher in his details. Moreover, the results of this research assists in understanding the ZT drunk driving laws, which are quite complex in nature (Carpenter, 2004).

The National Highway Systems Designation Act was passed by the Congress in the year 1995. According to this law, the states were liable to face funding penalties in case of deviation from additional strict driving laws aimed at reckless youth and drunk drivers. Briefly the laws are stated as follows: drivers under 21 were to be considered under ZT laws; drivers under 21 were also entitled to follow the blood alcohol content restrictions of BAC level at or above 0.02, otherwise they were to be considered according to laws. It was required that in case of violation the confiscation and cancelation of license was made sure. At the end of July 1998, the Act was complied by all the states (Carpenter, 2004).

The research also presented statistics about the awareness of the laws presented after the act. According to the study a moderate result was found in state of California, New Mexico and New York giving 65, 34 and 71% of youth awareness quotients concerning the laws of ZT (Carpenter, 2004).

Currently only one study agreeing to allow lower blood alcohol limits for younger drivers is presented which discusses drinking behaviours, driving and restrictions. An elaborate study carried out encompasses Monitoring The Future surveys held at school level studies different elements concerning driving, drinking and restrictions considering the youth, which include: drinking levels, driving while drunk, travelling with drunk driver and amount of travel. During the period 1984 to 1997, around 30 states which legalized lower alcohol levels, were included in the cited research. The research presented relative values and was based on theoretical results. According to the research results it was reported that lower alcohol levels legalization caused around 20% decrease in driving while drunk. However, decreased level of drinking was not a dependent variable in this context (Carpenter, 2004).

Various other researchers have considered effects of implementation of driving restrictions on the drinking behaviour of the drivers. Another dimension concerning insurance and liabilities was studied by using BRFSS data evaluation of more strict laws. According to the research findings, there was a decrease in frequency of heavy drinking however moderate drinking and driving while drinking were consistent.

Various other studies have recognized the factor of fatalities and casualties when strict drinking laws were in place, specifically the ZT laws. A number of researches reported lower fatality rates after ZT implementation. Furthermore, statistical results claiming a decrease in fatalities after implementation of ZT policies were presented. A recent research also founded after studying 50 states complying with ZT laws that the results were statistically identical (Carpenter, 2004).

Considerably, the lower standards of BAC were not suggested only for the youth but also for the adults in some cases. Various states have legalized 0.08 BAC for adults compared to 0.1 which were legalized earlier. Researches presenting deviation towards legalizing of lower BAC levels also show that these limitations were established in a struggle to decrease road fatalities related to drinking. Research also depicts that a state legalized lowered levels of 0.08 BAC endorsed 7% decreases in fatalities at roads (Carpenter, 2004).

The third Review: Carpenter's article has been selected as the third policy analysis paper for this article. Carpenter basically measured Ontario's Zero Tolerance & Graduated Licensing Law in his paper. The paper was vital towards assessing the effect of Zero Tolerance (ZT) policy on the alcoholic driving among youngsters. A new license system was proposed in Ontario, Canada on April 1, 1994, as stated by Carpenter (2006) with the name of Graduated driver license (GDL). This system was based on the eligibility of youth for driving in which the blood alcohol content (BAC) was set at zero. Moreover, for evaluating the impact of policy of Zero Tolerance (ZT) on the reduction of alcoholic and drunk driving in youngsters, the data of 1983-2001 Ontario Student Drug Use Surveys (OSDUS) was also taken into consideration by the researcher. The results showed a considerable decrease of 5% in the alcoholic driving rates of youngsters after the implementation of law. Furthermore, the youngsters reported lower legal obligations after the adoption of policy of ZT. However, it was revealed after the proper investigation of the data that the reduction that has been found is not a new trend. Instead it had been observed from1980s till 1990s. Previous records regarding the decreasing trend in drunk driving during the era of 1980 and 1990 or the statistics that showed decline in it for short terms around 1994 was either unreliable data or accounted for insignificantly smaller periods. The above findings were more inclined towards finding the variation in the consequences of young teenagers and adults by implementing the control through difference-in-differences method. Likewise, the drinking contribution did not seem to get any vigorous impact as reported by the researcher. Hence, the research revealed that the decrease in the road accidents of youth in Canada over the past years was not the result of the implementation of Ontario's law targeted towards alcoholic young driving (Carpenter, 2006).

United States governmental bodies have been engaged in an effort to lessen the casualties happening due to the young drunk driving by proposing various laws over the past years. Among these laws, Zero Tolerance (ZT) has proved to be the most effective one in which the legal blood alcohol content (BAC) for young drivers has set to be the minimum. This has further been supported by various studies that such policies are vital towards lessening the casualties cause due to alcoholic driving, and also witnessed the self-determined intake of alcohol by juveniles (Carpenter, 2004).

The governmental bodies of U.S. And Canada over the past era have shown considerable strictness towards the laws governing drunk driving. One of the measure initiatives and components of the driving system is the graduated driver licensing (GDL) proposed in Ontario in which ZT policy was implemented for the young drivers aged from 16 and above. However, the youngsters who turned 16 before the employment of ZT laws having their prior licenses were free from following such laws. Although there has been other ZT laws proposed by other provinces of Canada but a little attention has been catered towards the impact of those in literature (Carpenter, 2006).

Carpenters determined that the government of Ontario, Canada, launched a graduated driver licensing system on April 1, 1994, which was vital towards the reduction of young drunk driving casualties. This system also facilitated the young drivers with the liberties and rights of driving. There were several limitations pertaining to the places and locations for those youngsters who happened to have just started their process of getting G1 licensing. In addition to such restrictions, it was also proposed that a mature driver must also be present in car throughout the driving period of youth having a G1 license and the driving times were also determined for them (Carpenter, 2006).

Once, the young drivers pass from the G1 phase, the second phase is the G2 phase in which limitations are relatively smaller than the prior one followed by the road test and more liberties. Both the phases are the probation periods for the youths which last for 20 months in which youngsters are strictly prohibited to the alcoholic intake before and during driving by implementing a Zero Tolerance policy, the defilement of which leads to strong penalties and sometimes 30 days suspension of license (Carpenter, 2006).

However, the youngsters who turned 16 before the employment of ZT laws having their prior licenses could gain different liberties and rights and were also free from following such laws. The government of United States also implemented Zero Tolerance policy and graduating licensing system separately because for them they were two separate systems. However, in some states of U.S., both the laws were exercised together as a set with the ZT laws usually heading the GDL due to the threats about the reduction of highway funds that had been imposed on them from the U.S. federal law of 1995. Similarly, Canada implemented both of these laws simultaneously. Therefore, U.S. started its implementation of ZT policies from 1990-1997 prior to the implementation of ZT policies in Canada in 1994-1998 (Carpenter, 2006).
