Tractor accidents in Swedish traffic

The objective of this study is to reach a better understanding of accidents on Swedish roads involving tractors and to suggest ways of preventing them. In an earlier study we analyzed police-reported fatal accidents and accidents that led to physical injuries from 1992 to 2005. During each year of this period, tractors were involved in 128 traffic accidents on average, an average of 7 people were killed, 44 sustained serious injuries, and 143 sustained slight injuries. The number of fatalities in these tractor accidents was about 1.3% of all deaths in traffic accidents in Sweden. Cars were most often involved in the tractor accidents (58%) and 15% were single vehicle accidents. The mean age of the tractor driver involved was 39.8 years and young drivers (15-24 years) were overrepresented (30%). We are now increasing the data collected with the years 2006-2010 in order to study the changes in the number of accidents. Special attention will be given to the younger drivers and to single vehicle accidents. Based on the results we aim to develop suggestions for reducing road accidents, e.g. including measures for making farm vehicles more visible and improvement of the training provided at driving schools.     

Occupational accidents among elderly farmers in Sweden

The workforce in many countries nowadays is becoming older due to demographic change. Compared with many other occupations, farmers often work until a higher age. This study analysed occupational accidents to farmers in Sweden from an age perspective using data on 223 work injuries on farms and 990 road accidents involving tractors. The results showed that older farmers were not significantly more often injured than younger farmers, but appeared to suffer more hits and kicks from animals and were involved in more vehicle accidents than younger farmers. Older tractor drivers were more often involved in road turning accidents and in overtaking accidents involving private cars. Older farmers also sustained more skeletal injuries and took longer to heal after an accident.     

WILL RETARDING THE INFORMATION FLOW ON AUTOMOBILE RECALLS AFFECT CONSUMER DEMAND?

Recently the National Highway Traffic Administration changed its policy concerning the public announcement of safety-related automotive recalls. This paper examines whether consumers continue to use recalls as an input in their decision to purchase an automobile. It was found that over the 1977-81 period, severe recalls adversely affected the demand for the model recalled, while benefiting substitutes of other manufacturers.     

"MY WIFE KNOWS BEST" A COMPARISON OF EVENT DATING ACCURACY BETWEEN THE WIFE, THE HUSBAND, THE COUPLE, AND THE BELGIUM POPULATION REGISTER

The problem of memory bias in retrospective data has been studiedfor short-term retrospective recall and for frequently occurringevents, but little has been written on how questionnaire designcan improve memory of personal events over a very long retrospectivetime period. This study offers a new approach to the problemby using a sample survey conducted in Belgium that allows thecomparison of recall accuracy not only between the husband andthe wife but also the couple together through the use of NationalPopulation Register data. The sample data support findings fromcertain psychological experiments that respondents' errors inevent dating are generally in years, and not in months, andfurthermore that this pattern is not general and is relatedto the event itself. Subsequently, the year of the birth ofa child, which has an annual significance, is generally recalledaccurately; the year of a change of residence, however, is oftenerroneous. Results of the log-linear models show that the oddsof recalling an incorrect year of a move are significantly decreasedif an event with annual significance occurred around the sametime period. Design of retrospective questionnaires should takeinto account the fact that time units are not recalled equallyfor differing autobiographical events, and that dating accuracycould be improved through use of parallel event questioning.Correlations between dating errors and omissions, and the possibilityof a "chain of errors" in responses, are also examined.     

DOES SOCIAL CAPITAL PROMOTE SAFETY ON THE ROADS?

I present evidence that social capital reduces traffic accidents and related death and injury, using data from a 10‐year panel of 48 U.S. states. The econometric challenge is to distinguish the causal effects of social capital from bias resulting from its correlation with unobservable characteristics by state that influence road risks. I accomplish this by employing snow depth as an instrument, and by restricting attention to summertime accidents. My results show that social capital has a statistically significant and sizable negative effect on crashes, traffic fatalities, serious traffic injuries, and pedestrian fatalities that holds up across a range of specifications.

User acceptance of cooperative maneuver-based driving--a summary of three studies

Modern cars offer drivers support with the help of a number of driver assistance systems. Those systems aim to relieve drivers through assumption of sub parts of the driving task (e.g. in case of an Adaptive Cruise Control by regulation of vehicle speed and time gap to preceding vehicle). Today, systems are controlled and monitored separately which leads to efforts to combine the functionality of all systems in an overlying assistance for drivers. The approach of the University of Technology Darmstadt is called Conduct-by-Wire and can be seen as a cooperative maneuver-based driving paradigm, where the driver gives maneuver command to the systems which are automatically executed. This paper summarizes the results of three studies which investigated the user acceptance of this driving paradigm. Overall, it can be said that the acceptance of the system depends on personal traits of the driver and on the driving situation. Almost all participants are willing to use Conduct-by- Wire for routine tasks such as commuting, which makes the systems interesting for company cars. Still, there remain a number of drivers who are not willing to use such a highly automated system at all.     

THE RISE OF SERVICES,DEINDUSTRIALIZATION, AND THE LENGTH OF ECONOMIC RECOVERY

Economic recovery is longer in service‐providing economies than in goods‐producing economies. Services cannot be produced and inventoried ahead of demand; goods can. We are the first to document this macroeconomic repercussion of the sectoral shift away from the secondary sector toward the tertiary sector, that is, of deindustrialization and the rise of services. We distinguish between nontradable services and all other sectors, using U.S. state‐level employment data for post‐1960 recessions. Concerns over the endogeneity of services are addressed in two ways: by using 3‐year pre‐recession averages of sector shares, and separately by invoking instrumental variables. Our results are robust to alternative specifications. The increase in service production and deindustrialization in the United States over the last half‐century lengthens the trough‐to‐peak employment recovery from recessions by about 40%.

The Effect of French Television Sexual Program Content on the Recall of Sexual and Nonsexual Advertisements

This study examined the impact of television program sexual content and explicit sexual advertisement content on memory for advertisements. Eighty-two French participants, aged 18 to 48 years, watched either a sexual program (Sex and the City) or a nonsexual program (Friends), with three sexual and three nonsexual adverts embedded within it. They then completed free- and cued-recall questionnaires testing their memory of the advertisements, as well as a gender identity scale. Overall, sexual advertisements were recalled (in free recall) better than nonsexual advertisements. Participants were found to recall adverts significantly better within the nonsexual program than within the sexual program. No interaction was found between program type and advertisement type: Sexual adverts were recalled better than nonsexual adverts within both programs. Males and females recalled sexual adverts equally, with no mediating effect of gender identity. Implications and limitations of the study are discussed.     

“THE WAR FOR THE FARE”: HOW DRIVER COMPENSATION AFFECTS BUS SYSTEM PERFORMANCE

Prior to 2007, two systems of bus driver compensation coexisted in Santiago, Chile: one paid drivers per passenger transported, while the other paid a fixed wage. Per‐passenger drivers engaged in “The War for the Fare,” altering their driving patterns to compete for passengers. Examining these systems on similar routes in Santiago, we observed two key findings. Compared with the fixed‐wage system, the per‐passenger system leads to (1) 13% shorter passenger wait times, via reduced bunching of buses and (2) 67% more accidents per kilometer driven, via more aggressive driving. We discuss implications for the design of incentives in public transit. (JEL L92, M52, R41)     

Is Speeding a Form of Gambling in Adolescents?

Speeding is a major contributor to motor vehicle accidents, which are the leading cause of death in adolescents. This study compares the extent to which adolescents with gambling behavior and substance use reported driving over the posted speed limits (“speeding”). Florida adolescents ages 13–17 (n = 1051) were surveyed, and asked about gambling activities, problems related to gambling, substance use, demographic questions, and speeding. Of the 562 respondents who were drivers, the gender distribution was 52.1% male and 47.9% female. Of those respondents, 76.9% were Caucasian, 6.8% were African American, 10.1% were Hispanic, and 6.1% were Native American/Asian/Other. Simple correlation analysis revealed that self-reported speeding is significantly related to gambling behavior and substance use. When a linear regression model was used, four factors showed the most significant influence on self-reported speeding: past year gambling tendency, age, trouble with the police due to drinking, and tranquilizer usage. Gambling behavior and high-risk speeding (driving ≥ 10 mph over speed limit) also were noted to be positively correlated. Our data indicate a relationship between risky driving, gambling, and other risk-taking behaviors in adolescents, and support the hypothesis that speeding may be a form of gambling behavior in this age group.     

IDENTIFYING CHANGES IN THE SPATIAL DISTRIBUTION OF CRIME: EVIDENCE FROM A REFEREE EXPERIMENT IN THE NATIONAL FOOTBALL LEAGUE

Between the 2009–2010 and 2010–2011 seasons, the National Football League (NFL) repositioned one of its officials in order to prevent injuries among officials. This creates a quasi‐experiment for studying how a change in the extent of policing affects detection of offenses. Using play‐by‐play data from the 2009–2010 and 2010–2011 NFL season, I estimate how the detection of offensive holding changes when the positioning of an official changes. I find that there is approximately a 20 increase in the number of offensive holding penalties called after the NFL repositioned the official. Penalties called on defensive linemen fell as a result of the repositioning. Overall, there was no change in the total number of penalties called. Using the estimated change in the probability of a penalty, I estimate the probability of an official calling a penalty. I infer that NFL officials detect approximately 60% of crimes committed on the field. (JEL K4, Z0, D0)     

EVALUATING THE EFFECTIVENESS OF CHILD SAFETY SEATS AND SEAT BELTS IN PROTECTING CHILDREN FROM INJURY

Young children are required to use child safety seats, and the age threshold at which children can legally graduate to seat belts has steadily increased. This article tests the relative effectiveness of child safety seats, lap‐and‐shoulder seat belts, and lap belts in preventing injuries among motor vehicle passengers aged 2–6 yr. We analyze three large, representative samples of crashes reported to police, as well as linked hospital data. We find no apparent difference in the two most serious injury categories for children in child safety seats versus lap‐and‐shoulder belts. Child safety seats provide a statistically significant 25% reduction in the least serious injury category. Lap belts are somewhat less effective than the two other types of restraints but far superior to riding unrestrained. (JEL I18)     

Product recalls and organizational learning: ConAgra's responses to the peanut butter and pot pie crises

This study focused on ConAgra's communication strategies utilized during its peanut butter and pot pie product recalls. A content analysis revealed that ConAgra handled each recall differently, with little evidence of organizational learning. The use of strategic ambiguity during the peanut butter recall enabled ConAgra to respond more successfully to consumers than during the pot pie recall.     

CONSOLIDATING THE EVIDENCE ON INCOME MOBILITY IN THE WESTERN STATES OF GERMANY AND THE UNITED STATES FROM 1984 TO 2006

The cross‐national intragenerational literature has often analyzed income mobility within short time periods over which mobility might reasonably be thought of as invariant. Here, we argue that a great social transformation—German reunification—abruptly and permanently altered mobility. Using standard measures (with panel data for the western states of Germany and the United States) over the period 1984–2006, we find the conventional result that income mobility is greater in Germany. But when we cut the data into 5‐year windows, we find that income mobility declines significantly over the years immediately following reunification in Germany but not in the United States, using both measures.

DEAD ON ARRIVAL: ZERO TOLERANCE LAWS DON'T WORK

By 1998, all states had passed laws lowering the legal blood alcohol content for drivers under 21 to effectively zero. Theory shows these laws have ambiguous effects on overall fatalities and economic efficiency, and the data show they have little effect on driver behavior. A panel analysis of the 1988–2000 Fatality Analysis Reporting System indicates that zero tolerance laws have no material influence on the level of fatalities, while quantile regression reveals virtually no change in the distribution of blood alcohol content among drivers involved in fatal accidents.

Shatterproof on its rating pilot for SUD treatment programs

Shatterproof launched its rating system for addiction treatment programs with a $5 million pilot, the company announced in December, with funding coming mainly from insurance companies and grants (see ADAW, Jan. 14). The project began a year ago (see ADAW, Jan. 15, 2018) but is now moving forward. ADAW caught up with Sam Arsenault, director of national treatment quality initiatives for Shatterproof, last week about the project.     

THE ROLE OF THE BIDDING PROCESS IN PRICE DETERMINATION: JUMP BIDDING IN SEQUENTIAL ENGLISH AUCTIONS

This paper uses data collected from a series of public auctions of used cars in New Jersey to examine how strategic bidding affects price determination in open‐outcry English auctions. “Jumps” in the bidding, which occur when a new offer exceeds the old offer by more than the minimum bid increment, are highly pervasive and consistently related to the item’s presale estimated price. The size of the jumps is not affected by the selling order, however. This jump bidding pattern suggests that open‐outcry auctions are more appropriately interpreted with models that assume common‐item valuations rather than models assuming private valuations.

Domestic violence among male and female patients seeking emergency medical services

Gender differences among a cohort of injured patients seeking emergency medical services were examined with respect to their experiences as perpetrators and/or victims of domestic violence. Contextual issues, including violence initiation, emotional and behavioral responses to partner-initiated violence, and injury frequency and severity were analyzed. Women reported male partner-initiated violence more frequently than men reported female partner-initiated violence. Behavioral responses to partner initiated violence varied. Women were more likely to report using force back and to involve law enforcement. Women were more likely to be injured in a domestic assault over their lifetime, within the last year, and at the time of recruitment. Comparison of injury severity revealed that women reported higher rates of injuries than men in all possible severity categories. Women also reported experiencing more fear than men during partner-initiated violence, as well as being subjected to larger numbers of dominating and controlling behaviors, and greater intimidation secondary to their partner's size. Understanding contextual differences in partner violence for women and men has significant implications for policy development, identification, treatment, and referral of patients identified as living in violent relationships.     

ENVIRONMENTAL POLICY AND VEHICLE SAFETY: THE IMPACT OF GASOLINE TAXES

Policies to reduce carbon emissions by vehicles, such as fuel economy standards and gasoline taxes, have impacts on vehicle weight and thus on safety. This paper develops a model that separately identifies the impact of vehicle weight on mortality and selection effects that impact accident propensity. The main results are that (1) the safety externalities associated with heavy vehicles are greater than the environmental ones; (2) under fuel economy standards, vehicle weights have recently decreased with little likely effect on accident deaths; and (3) similar environmental benefits could be combined with substantial reductions in deaths by implementing higher gasoline taxes.
