Abstract

BACKGROUND

A large body of research has pointed out that advertising has an impact on gambling behavior. However, little is known about how actual gambling marketing regulations impact online gambling behavior and marketing expenditure. Recently, a Spanish law-the Royal Decree 958/2020-came into force, which, in general terms, limits the marketing of gambling products. The current study aimed to examine the effect of the Spanish Royal Decree 958/2020 on gambling behavior (i.e., new accounts, active accounts, deposits, and total money bet) and marketing expenditure (i.e., advertising, bonuses, affiliation, and sponsorship) based on data from the Directorate General for Regulation of Gambling.

METHODS

We used Seasonal Autoregressive Integrated Moving Average (SARIMA) models to examine the impact of the implementation of Royal Decree 958/2020 on both online gambling behavior and marketing expenditure.

RESULTS

The entry into force of the Spanish Royal Decree (applied between November 2020 and August 2021) led to a permanent decrease in gambling behavior, in particular new accounts (-263k; p = .003) and total money bet (-€216M; p = .034). Additionally, regulatory measures had an impact on marketing strategies, specifically, reducing money earmarked for advertising (-€20M; p = .004), bonuses (-€2.6M; p = .048), and sponsorship (-€5.3M; p < .001).

CONCLUSION

These findings demonstrate that regulatory measures aimed at limiting gambling advertising, bonuses, and sponsorships impact new accounts (i.e., new gamblers) and total money gambled, but hardly active accounts (i.e., regular gamblers). This study can serve as a model for countries where gambling advertisements have not yet been regulated.

Drug Control Governance: Regulatory Bodies and Their Impact 01:03

146

Drug control governance involves the oversight and regulation of pharmaceuticals to ensure their safety and efficacy while preventing illegal drug use and trafficking. Regulatory bodies, including the US Food and Drug Administration (FDA) and the European Union's European Medicines Agency (EMA), play a central role in this process. These agencies evaluate the safety and efficacy of drugs before they can be marketed. They fund clinical trials and assess the benefits and risks associated with...

Drug Regulation 01:25

Drug regulation encompasses the management of drug usage by evaluating its safety and efficacy through assessments conducted by regulatory authorities. Regrettably, the history of drug regulation is marred by several catastrophic events. One such incident is the Elixir Sulfanilamide tragedy, in which the toxic compound diethyl glycol was included in a sweet-tasting medication, leading to numerous fatalities. This event prompted the enactment of the Food, Drug, and Cosmetic Act in 1938. Under...

Bias 01:22

Bias refers to any tendency that prevents a question from being considered unprejudiced. In research, bias occurs when one outcome or answer is selected or encouraged over others in sampling or testing. Bias can occur during any research phase, including study design, data collection, analysis, and publication.
In statistics, a sampling bias is created when a sample is collected from a population, and some members of the population are not as likely to be chosen as others (remember, each member...

Framing Effects 03:26

Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in...

Longitudinal Research 02:20

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches 01:23

Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...
