Knowing the negative effect of sports manipulation for the sport and society, as well as the problems that is facing the Macolin Convention in its ratification, I decided to do this research in order investigate the phenomenon of match-fixing, controversial issues about the online gambling and potential effect of ratifycation of the convention and its entry into force. I was totally surprised when I found out so many International business law issues are covered in this topic. The sports betting markets are similar to the stock market, where odds movement de- pends on the performance of the teams and players. The insider trading is similar to the match-fixing, where a pre-match information for the result is used in order to achieve a great profit. Memorandums of understanding between betting companies, sports governing bodies and public authorities are used to cover the lack of regulation in this area. In the same time there is a need of acceleration of negotiations for the ratification of the convention due to the spreading of the phenomenon of sports manipulation.

Athletes are not roulette chips, but sports gambling treats them as such. If the dangers of state sponsored sports betting are not confronted, the character of sports and youngsters’ view of them could be seriously threatened… just as legalizing drugs would lead to increased drug addiction, legalizing sports gambling would aggravate the problems associated with gambling. As a society, we cannot afford this result, and… legalizing sports gambling would encourage young people to participate in sports to win money. They would no longer love the game for the purity of the experience. Key words: major manipulations, harmful aspects, existing problems, legalizing sports gambling, ethics of sports

The U.S

In recent years, there has been a substantial rise in interest among academics and policymakers in the economics of gambling. A concomitant trend has been the implementation of major regulatory changes and modifications to the taxation of gambling markets in several nations. Examples include a fundamental change in the U.K. in 2001 from a turnover-based tax on betting operators to a tax based on gross profits, resulting in the effective abolition of taxation levied directly on bettors, followed in 2005 by extensive reforms to the gambling sector resulting from introduction of the Gambling Act. In the U.S., passage of the Unlawful Internet Gambling Enforcement Act of 2006 had profound implications for the global online gambling sector. There have also been numerous regulatory changes to gambling in Europe, Asia, and Australia. These changes and rising concern regarding revenue generated from this activity have heightened interest in understanding the economics of this sector. Despite growing interest in the economics of gambling, there is no comprehensive source of path-breaking research on this topic. The purpose of this handbook is to fill this gap. Specifically, we divide the handbook into sections on casinos, sports betting, racetrack betting, betting strategy, motivation, behaviour and decision-making in betting markets, prediction markets and political betting, and lotteries and gambling machines.

Legislative Measures

Recent state legislation regulating fantasy sports contests may present a different type of threat to the nascent fantasy sports industry—the possibility that the U.S. Attorney General (or others) could invoke PASPA to enjoin the state law. This is the same law that prohibits states from legalizing traditional, single-game sports betting. Although PASPA has not yet surfaced as an obstacle to state legalization of DFS, it may emerge as an important issue as additional state legislative measures are introduced, particularly with a new U.S. Attorney General potentially taking a harder look at Internet gambling generally. Further, as more and more states begin passing laws legalizing daily fantasy sports contests, many have begun to question why some forms of sports gambling are allowed but not others. This chapter examines how PASPA could apply to state-sanctioned fantasy sports and provides an analytical framework for assessing the viability of such legislation under PASPA.

State Income

In May 2018, the Supreme Court overturned the Professional and Amateur Sports Protection Act, thereby allowing all states to offer sports betting. Prior to this, Nevada was the only state with unrestricted sports betting. Using sports betting data from Nevada, we estimate long-run and short-run income elasticities to determine the growth and volatility of sports betting as a tax base. Sports gambling grows at a similar rate as state income and is stable and insensitive to short-run shocks to income. However, the amount of money kept by casinos, and hence the state, is small compared to other traditional tax bases.

This paper transfers and adapts the Black-Litterman portfolio management model and its subsequent generalizations to the characteristics and specificities of assets quoted on sports betting markets. The results show that these assets are suitable for the application of portfolio management models with the possible inclusion of investors’ opinions. Information based on the variability of market prices and the attention received by NBA teams in Google Trends is successfully used to simulate the opinions expressed by a hypothetical portfolio manager. Furthermore, the assets are suitable for inclusion in portfolios in which managers are seeking returns uncorrelated with other assets.

Abstract Introduction Children are susceptible to problems with gambling because of developmental and cognitive immaturities, as well as a sensitivity to peer pressure and marketing. Sources of data This review uses recent UK data from the Gambling Commission and from the Avon Longitudinal Study of Parents and Children, and evidence from recent reviews of gambling in children and adolescents. Areas of agreement The prevalence of gambling in children worldwide and in the UK is stable, having generally decreased since 2013. Online gambling is increasing in children and young people. A small minority of adolescents who gamble develop a gambling disorder. Adolescents who have problems with gambling tend to have lower self-esteem and a history of hyperactivity and impulsivity, are more likely to have parents who gamble, report less parental supervision and to use more alcohol than their peers. Areas of controversy Children’s access to slot machines, the relationship between gaming and gambling, and social media advertizing of gambling targeting children. Growing points An increase in online gambling and in-play sports betting by adolescents and the use of skins betting in video gaming. Areas timely for developing research: impact on young people of betting on e-gaming. How best to protect children from early exposure to gambling in the current internet age. Implications for clinicians Need to be aware of the growing and complex phenomenon of gaming and gambling, and implications for the mental health of children and adolescents. The effective management of gambling disorders in children and adolescents requires close working with families.

Gambling disorder is of great clinical and social relevance since it seriously affects people who suffer from it. More recently, the Internet has exacerbated the problem with online casinos, poker, and sports betting. However, there is little evidence of this problem, and we know of no diagnostic questionnaire. The main objectives of this study were to develop the Online Gambling Disorder Questionnaire (OGD-Q) for adolescents, evaluate its main psychometric properties, and establish diagnostic criteria to differentiate pathological from non-pathological online gamblers. We conducted a study in 16 schools across seven regions of Spain, sampling 2691 adolescents, 883 of whom had reported some online gambling experience. Of those, 602 were boys (68.2%) and 281 were girls (31.8%) Sampling was non-probabilistic and incidental. Mean age and standard deviation were 14.25 ± 1.55 (11–19 years). Confirmatory factor analysis yielded a one-dimensional model with a good fit. The reliability indicators were satisfactory (>0.94). The scores on the OGD-Q were related to other constructs, such as Internet gaming disorder, problematic Internet use, and nomophobia. Participants classified as having problems or being at risk of online gambling disorder presented significantly more stress, anxiety, and depression. Participants categorized as having online gambling disorder comprised 0.89% (n = 24) of the total sample and 2.71% of those who have gambled at some time. We discuss these findings and their practical implications in this article and propose future lines of research.

There is a wide literature on sports betting markets, a literature that examines the informational efficiency of these markets and uses them as laboratories to test for possible impacts of psychological factors on financial markets. The innovation of this study is the examination of price behaviour in an in-play betting market – namely that for one-day cricket. Cricket provides an ideal construct in which to examine in-play market behaviour, as it is a sport where outcomes can be calibrated as good news or bad news on a play-by-play basis. The results from an examination of over 8000 balls corresponding to over 8000 “news events” shows that the in-play betting market is one in which news is impounded rapidly into betting odds. There is also evidence that odds have a level of predictive ability with respect to outcomes from balls before they are bowled. Further, there is evidence of a drift in odds subsequent to the outcome of balls being known.

The international sports betting markets are becoming more global, but there is still a large concentration of local bettors in gambling markets of individual countries. Home loyalty and other patterns of human behavior might lead to odds for international competitions being different in different countries with less favorable odds being quoted in the home country; the home bias effect. In this paper we explain the logic of this phenomena and examine a small data set to show the existence of the bias in three different sports: tennis, golf, and European football. We also suggest ideas for a more thorough investigation of the home bias phenomenon.

REVISITING THE “HOT HAND” HYPOTHESIS IN THE NBA BETTING MARKET USING ACTUAL SPORTSBOOK BETTING PERCENTAGES ON FAVORITES AND UNDERDOGS

The “hot hand” hypothesis was first investigated in sports betting markets by Camerer (1989) and Brown and Sauer (1993), who examined if professional basketball teams truly could become “hot”, implying a change in their actual skill level, and if the betting market believes teams become “hot” and over bet the teams on winning streaks.   Both assumed that book makers operated a balanced book.  Recent evidence suggests that book makers do not set point spreads to balance betting on either side of games.  Book makers may price as a forecast or shade point spreads to exploit known biases.  The “hot hand” could exist, but closing point spreads may not reflect this bias due to an unbalanced book.   Using a 6 season sample of NBA betting market data, we show wagering against the “hot hand” does not win more than implied by efficiency.  However, OLS and two-stage least squares regression models show that bettors believe in the hot hand, as teams on streaks attract a significantly higher number of bets.  This illustrates that the public believes in the hot hand, reflecting an actual behavioral bias.  This bias exists even though the closing price serves as an optimal and unbiased forecast of outcomes.
