Essays on pre-commitment in Germany
(2019) Strohäker, Tanja; Becker, Tilman
As a superordinate topic, the thesis analyzes and evaluates selected pre-commitment tools that are available in the German gambling context. Pre-commitment is a form of self-binding that allows gamblers to limit money and time spent on gambling before they start a session. This is based on the underlying idea that gamblers will benefit from the fact that expenses and duration of stay are determined before commencing a gambling session, when they are not yet in a state of emotional arousal and hence more capable of deciding rationally. The most extreme form of limitation is the exclusion from gambling. While other countries established formalized pre-commitment systems allowing gamblers in arcades to limit time and money spent on gambling and/or self-exclude from establishments, Germany has not established such a comprehensive scheme yet. There are, however, certain types of gambling, for which at least exclusions are regulated, enforced and externally binding. To further improve the exclusion schemes, it is important to understand the drivers of exclusions. Hence, the second and third chapter of this thesis analyze the drivers for the variation of the number of exclusions between municipalities. Next to sociodemographic characteristics, the models also contain availability measures. Other than most countries, Germany distinguishes between casinos and gambling arcades. Casinos offer table games as well as automated gambling, whereas gambling arcades only provide electronic gambling machines (EGMs hereafter). Both establishments naturally attract different clientele, hence, a thorough examination of these two different types of gamblers is important. Chapter two concentrates on analyzing which variables drive the differences in the number of exclusions from casinos throughout German municipalities. This chapter aims to analyze the degree to which sociodemographic factors and proximity measures can be used to explain the variation in the number of excluded gamblers across German communities. At the time of the analysis, the exclusion file consisted of 31,118 unambiguously assignable entries distributed among 3,091 communities. The results of the study suggest that excluders are more likely to be male, between 30 and 39 years old, and less likely to be single. As only few of the sociodemographic variables yield significant results, we can only partially confirm the well-established risk factors for problematic or pathological gambling. Additionally, the results show that the number of exclusions increases with close proximity to gambling establishments. The distance to the closest casino has a negative impact on exclusions. This is backed up by the finding indicating that in relation, there are more exclusions in communities where casinos are located directly. Chapter three deals with a similar research question, which this time is tailored to excluders from gambling arcades in Hesse, Germany. The aim of the paper is to identify significant predictors that are useful in explaining the variation of exclusions between different Hessian communities. This data set contains 11,902 exclusions that are distributed among 191 Hessian communities. Next to sociodemographic factors, we control for three different accessibility measures in two models: the number of electronic gambling machines in model I as well as the number of locations and density of gambling machines at a location in model II. Considering the sociodemographic variables, the explanatory power of the cross-sectional models is rather low. Only the age group of 30 to39-year-olds and those who are not in a partnership (in model I) yield significant results. Hence we are again not able to determine a specific sociodemographic background for self-excluders. The accessibility variables, on the other hand, turn out to be significantly associated with the number of exclusions. All three of them are statistically significant and their association is positive. The fourth chapter deals with self-limitation, which is another type of pre-commitment. As there has existed no formalized limit scheme in Germany, it is left to evaluate voluntary and self-initiated limits that are frequently used as self-management strategies by gamblers, independent of their gambling severity. The analysis yields promising results. 50 percent of gamblers use at least one limit. There are significant differences in most variables concerning gambling behavior. Gamblers with limits consistently spend significantly less time and money in gambling arcades. The overarching goal of this doctoral thesis is to provide insights considering pre-commitment tools that can be used in the German gambling context. It shows that pre-commitment is an accepted and widely used instrument with positive consequences for gamblers. It is therefore worthwhile in any case to further expand the existing programmes.
