Casinos use Cash (Free Play), Direct Mail and E-Mail Blasts, Buffet coupons, and Hotel Marketing among other offers in order to retain their loyal customers and also to invite new players to join their loyalty club. This study assessed the effectiveness of such promotions in terms of generated gaming revenues. Data from two mid-size casinos are used for this purpose. The method of Bayesian general linear models is used to determine the effects of various promotions on gaming revenue streams. Several promotion types were shown to have a significant impact on gaming revenue streams.
赌场利用现金(免费游戏)、直邮和电子邮件群发、自助餐优惠券和酒店营销等优惠活动来留住忠实客户,并邀请新玩家加入其忠诚俱乐部。本研究评估了此类促销活动在创造博彩收入方面的效果。为此使用了两家中型赌场的数据。采用贝叶斯一般线性模型的方法来确定各种促销活动对博彩收入流的影响。结果表明,几种促销类型对博彩收入流产生了重大影响。

Betting Market-Based Expectations and NFL Coach Retention and Dismissal 基于市场的期望与 NFL 教练的去留
Pub Date : 2023-07-19 DOI: 10.5750/jgbe.v16i1.2038

Performance compared to expectations is important in evaluation of Chief Executive Officers, managers, and coaches. In many industries, expectation metrics are difficult to estimate or obtain. In professional sports, however, futures markets exist for season performance. In many sports, such as the NFL, there exists a wagering option on season win totals. A season win total is an over/under bet on the number of wins a team will have in a given season. We utilize this market to calculate actual versus expected performance and include this in a model of coach retention. The issue of treatment discrimination of minority coaches is explored.
在评估首席执行官、经理和教练时,绩效与期望值的比较非常重要。在许多行业,预期指标很难估计或获得。然而,在职业体育中,存在着赛季表现的期货市场。在许多体育项目中,如美国国家橄榄球联盟(NFL),都有赛季总胜场的投注选项。赛季总胜场是对一支球队在特定赛季中获胜场次的大小投注。我们利用这一市场来计算实际表现与预期表现,并将其纳入教练留任模型。我们还探讨了少数族裔教练的待遇歧视问题。

Power Imbalances, Market Concentration, and High Jackpots: The Case of EuroMillions 权力失衡、市场集中和高额奖金:欧洲百万彩票案例
Pub Date : 2023-07-19 DOI: 10.5750/jgbe.v16i1.2103
Álvaro Muñiz
While the EuroMillions game has been in operation since 2004, there has been limited analysis of its demand and no research on potential power imbalances within the organization and their dependence on jackpot size. This study utilizes EuroMillions sales data at the country level to examine the distribution of market power within the organization and its historical trends. Market concentration is evaluated using the Herfindahl Hirschman index (HHI), and the relationship between the HHI and jackpot size is assessed using sales data at the draw level for all game operators. Findings indicate that power imbalances exist within the EuroMillions organization, partly due to the impact of the jackpot size, which appears to stimulate demand for EuroMillions tickets more in certain countries than in others.
虽然 "欧洲百万 "彩票游戏自 2004 年开始运营,但对其需求的分析却十分有限,也没有对该组织内部潜在的权力不平衡及其对大奖规模的依赖性进行研究。本研究利用 "欧洲百万彩票 "在国家层面上的销售数据,研究该组织内部的市场力量分布及其历史趋势。使用赫芬达尔-赫希曼指数(HHI)评估市场集中度,并使用所有游戏运营商的抽签销售数据评估 HHI 与奖池规模之间的关系。研究结果表明,欧洲百万彩票组织内部存在权力不平衡现象,部分原因是大奖规模的影响,大奖规模似乎在某些国家比在其他国家更能刺激对欧洲百万彩票的需求。

Ashutosh Kumar Singh
The coronavirus epidemic or Covid-19 started in Wuhan, China in December 2019 and has severely impacted all aspects of life worldwide. It has resulted in 216 million infections and 4.5 million deaths so far globally, and  In the present article, the impact of coronavirus on gaming revenue of the state of Nevada will be investigated. Gaming revenue time series data for the period January 1988 – November 2020 was obtained from the Gaming Control Board of Nevada. In addition to the trend and seasonality components, the terrorist attack of September 2011, the recession of 2008, and the coronavirus pandemic are also included in the Machine Learning (ML) prediction models for gaming revenues. The goals of this study are to estimate the effect of the coronavirus pandemic on gaming revenue of the Las Vegas Strip casinos, and to forecast gaming revenue and predict time to recovery. The results of this analysis show that the impact of coronavirus has been drastic, but the economic recovery has been rather fast.

COVID-19 has accelerated change in the casino sector, and it is likely to impact the performance of this industry for years. This study evaluates the potential for casinos to bounce back to pre-pandemic levels by addressing changing perceptions and priorities of their customers. A national survey of US casino customers was conducted to provide insight into what gamblers would like to see and, more importantly, what they expect from casinos when they return. The results offer implications for health and safety mitigation, vaccination protocols, and the preferences of loyal casino customers and “Big Spenders”. 
2019冠状病毒病加速了博彩业的变化,并可能在未来数年内影响该行业的表现。本研究评估了赌场通过解决客户不断变化的观念和优先事项,恢复到疫情前水平的潜力。一项针对美国赌场客户的全国性调查旨在深入了解赌客希望看到什么,更重要的是,了解他们重返赌场后对赌场的期望。研究结果为健康和安全缓解措施、疫苗接种方案以及忠诚的赌场客户和“大款”的偏好提供了启示。

Efficient Micro-Behaviors in Pari-mutuel Betting System and FL Bias Pari-mutuel投注系统中的有效微观行为和FL偏差
Pub Date : 2021-12-23 DOI: 10.5750/jgbe.v14i2.1946
Kazutaka Kurihara, Y. Tutiya
In this paper, we propose a model which simulates odds distributions of pari-mutuel betting system under two hypotheses on the behavior of bettors: 1. The amount of bets increases very rapidly as the deadline for betting comes near. 2. Each bettor bets on a horse which gives the largest expectation value of the benefit. The results can be interpreted as such efficient behaviors do not serve to extinguish the FL bias but even produce stronger FL bias.
在本文中,我们提出了一个模型,该模型在下注者行为的两个假设下模拟了对赌系统的赔率分布:随着投注截止日期的临近,投注金额迅速增加。2. 每个投注者都押注于一匹收益期望值最大的马。结果可以解释为,这种有效的行为不仅不能消除FL偏置,反而会产生更强的FL偏置。

A Multilevel Mixed Effects Model to Evaluate Effectiveness of Treatment for Problem Gambling 评价问题赌博治疗效果的多层次混合效应模型
Pub Date : 2021-12-23 DOI: 10.5750/jgbe.v14i2.1943
L. Pérez, Ana Rodríguez, A. Shmarev
Problem gambling treatment is a challenging present-day topic. This paper proposes an empirical model for evaluating the effectiveness of treatment for problem gambling using a sample of problem gamblers treated by a set of Spanish associations dedicated to gambling addiction issues. Data consists of multiple levels of nested groups (individuals and problem gambling recovery centres). A multi-level, mixed-effects logistic regression is used which permits controlling for unobserved heterogeneity across different problem gambling associations. The results seem to indicate that individual aspects such as age, family history, marital status or work situation, but also behavioural factors (previous dropouts, relapses during treatment, or consumption of other substances) are found to affect the effectiveness of treatment for gambling disorders. The analysis of the predictors for treatment efficacy may help treatment techniques to be adapted depending on the characteristics of individual patients and to evaluate programmes designed by treatment centres.
问题赌博治疗是当今一个具有挑战性的话题。本文提出了一个经验模型,用于评估问题赌博治疗的有效性,使用一组西班牙协会致力于赌博成瘾问题治疗的问题赌徒的样本。数据由多层嵌套组(个人和问题赌博康复中心)组成。一个多层次,混合效应的逻辑回归被使用,允许控制未观察到的异质性在不同的问题赌博协会。研究结果似乎表明,年龄、家族史、婚姻状况或工作情况等个人因素,以及行为因素(以前辍学、治疗期间复发或使用其他物质)都会影响治疗赌博障碍的效果。对治疗效果预测因素的分析可能有助于根据个别患者的特点调整治疗技术,并有助于评估治疗中心设计的方案。

An Effective Approach for Exploiting the Inefficiencies of the Italian Football Betting Market 利用意大利足球博彩市场低效率的有效途径
Pub Date : 2021-12-03 DOI: 10.5750/jgbe.v14i1.1857
Davide Alesina
In this paper, the author analyses the main inefficiencies of the Italian Serie-A betting market: in particular, using previous findings on the favourite-long shot bias, the team scoring home advantage and the league winner scoring advantage, a strategy aimed to outperform the market will be presented. By testing the betting scheme over the past 19 seasons, it was possible to obtain an average return per bet of 9.31%, with 16 of the 19 years resulting in positive financial returns. In order to verify the computations, different betting odds databases were used. The results obtained are particularly significant for two reasons: firstly all computations were performed on market average coefficients, leaving on the table an additional 3-4% of profit, which could be obtained by using best coefficients among bookmakers and secondly compared to market benchmarks and other betting strategies, the net profit is considerably higher. In particular other three strategies were used as a benchmark: the first one uses the favourite-long shot bias, the second one the Home factor and the third one the league favourite team advantage. All these betting schemes performed more poorly, with the second best strategy scoring on average 6% worse. After analysing possible future improvements, in the final section the author describes how the findings of this paper may be applied to other betting markets, such as different football leagues, basketball, hockey and tennis.
在本文中,作者分析了意大利意甲博彩市场的主要低效之处:特别是,使用先前的研究结果对最喜欢的远射偏见,球队得分主场优势和联赛冠军得分优势,旨在超越市场的策略将被提出。通过对过去19个赛季的投注方案进行测试,可以获得9.31%的平均投注回报,其中16年产生了正的财务回报。为了验证计算结果,使用了不同的投注赔率数据库。所获得的结果特别重要,有两个原因:首先,所有的计算都是在市场平均系数上进行的,在桌面上留下额外的3-4%的利润,这可以通过使用博彩公司之间的最佳系数来获得;其次,与市场基准和其他投注策略相比,净利润要高得多。特别是其他三种策略被用作基准:第一个使用最喜欢的远射偏见,第二个使用主场因素,第三个使用联盟最喜欢的球队优势。所有这些投注方案的表现都较差,第二好的策略平均得分差6%。在分析了可能的未来改进之后,在最后一节中,作者描述了本文的发现如何应用于其他博彩市场,如不同的足球联赛,篮球,曲棍球和网球。

iGaming versus Banking 游戏vs银行
Pub Date : 2021-12-03 DOI: 10.5750/jgbe.v14i1.1938
Dominic Cortis, Luke Spiteri
This work compares existing and emerging risks of the banking and iGaming industries. Moreover, whilst a solvency framework is established in the banking industry, this study researches the potential implementation of a solvency regime in the iGaming industry. Our literature review is complemented with semi-structured interviews held with 23 stakeholders working in risk management in Malta. The common risks identified were compliance with regulations, money laundering, liquidity and solvency risks. The banking industry highlighted credit, market and jurisdiction risks as specific risks faced by their industry – the latter being potential worry specific to the Maltese jurisdiction. iGaming experts highlighted financial, responsible gaming and market changes as specific risks for their industry. A formalised solvency framework would be beneficial to the iGaming industry by further enhancing its reputation. Finally, we find that more focus should be given to risk management in banks and iGaming operators to improve the relationship between both industries.
这项工作比较了银行和游戏行业现有的和新出现的风险。此外,在银行业建立偿付能力框架的同时,本研究还研究了在游戏行业实施偿付能力制度的可能性。我们的文献综述辅以与23位在马耳他从事风险管理工作的利益相关者进行的半结构化访谈。确定的共同风险是遵守法规、洗钱、流动性和偿付能力风险。银行业强调信贷、市场和司法风险是其行业面临的具体风险,后者是马耳他司法管辖区特有的潜在担忧。电子游戏专家强调,金融、负责任的游戏和市场变化是该行业面临的具体风险。一个正式的偿付能力框架将进一步提高游戏行业的声誉,从而有利于游戏行业。最后,我们发现银行和网游运营商的风险管理应该得到更多的关注,以改善两者之间的关系。
