The purpose of this study is to empirically examine the efficiency of Greek fixed-odds (offline) betting market as offered by OPAP for the period 2016–2019.

Using a four-year data sample of OPAP's opening and closing odds for football matches from all over the world and applying linear probability and probit models, the market efficiency is examined and the existence of possible anomalies is investigated.

The main findings of research suggest that although the odds are dominated primarily by favorite-longshot bias and secondarily by draw bias, this mispricing cannot prove profitable. However, the opening odds, the margin levels and the market structure provide information that is not fully captured by the closing odds, giving bettors profit opportunities. Thus, findings show that the semi-strong market efficiency is questionable. Finally, competition reduces commissions leading to more efficient odds.

The conclusions of this study are useful for football betting market and, particularly, for government authorities, bookmakers and bettors. Findings can be extended in future research to prediction tasks.

To the best of the authors’ knowledge, this is the first study about the Greek football betting market. The contribution to the literature lies on the one hand in the examination of a monopolistic land-based betting market, which is being squeezed and threatened by the more competitive online betting market, and on the other hand in the simultaneous examination of the opening and closing odds.

This paper aims to examine market inefficiencies in the National Football League (NFL) betting market from the 2003 season to the 2016 season.

The author examines the impact that division rivals and previously known determinants of inefficiencies have on the current NFL gambling market.

The results show that games against division rivals have a lower chance of the home team covering the spread and the chance the game will result in an over. This result demonstrates that the sportsbooks underestimate the familiarity that teams have with each other’s players, coaches and tendencies from playing each other twice per year. Moreover, using this result in conjunction with previous known inefficiencies, the author puts forth a model to test out of sample predictions. The results from these tests show profitable strategies in the point spread and totals market with a win rate of nearly 57 per cent.

Overall, this paper demonstrates inefficiencies in the NFL betting market that future bettors may be able to take advantage of.

The purpose of this paper is to examine the market demand of sport lottery in China from the following perspectives: available types and varieties of sport lottery, number of retail outlets, public welfare funds, promotion costs, per capita income, and population.

As the earliest province of issuing the sales of sport lottery and having one of the largest sales volumes in China, Guangdong Province was chosen for conducting the current study. Data were obtained from 14 sport lottery administration and distribution centers and statistics bureaus of 14 corresponding municipal cities. Multiple regression analysis was used.

Multiple regression analyses revealed that number of retail outlets, promotion cost, per capita income, and public welfare funds were positively (p<0.05) predictive of sport lottery sales; however, available types and varieties of sport lottery were not found to be significantly (p>0.05) related to total sport lottery sales. The findings are discussed in the context of theories and practices in the marketing and administration of sport lottery sales in China.

Similar studies are suggested to be conducted in provinces and regions beyond Guangdong Province.

This study combined socioeconomic characteristics of the population, lottery game characteristics and management factors for the first time.

The increasing globalization and technological advancements have increased the information spillover on stock markets from various variables. However, there is a dearth of a comprehensive review of how stock market volatility is influenced by macro and firm-level factors. Therefore, this study aims to fill this gap by systematically reviewing the major factors impacting stock market volatility.

This study uses a combination of bibliometric and systematic literature review techniques. A data set of 54 articles published in quality journals from the Australian Business Deans Council (ABDC) list is gathered from the Scopus database. This data set is used to determine the leading contributors and contributions. The content analysis of these articles sheds light on the factors influencing market volatility and the potential research directions in this subject area.

The findings show that researchers in this sector are becoming more interested in studying the association of stock markets with “cryptocurrencies” and “bitcoin” during “COVID-19.” The outcomes of this study indicate that most studies found oil prices, policy uncertainty and investor sentiments have a significant impact on market volatility. However, there were mixed results on the impact of institutional flows and algorithmic trading on stock volatility, and a consensus cannot be established. This study also identifies the gaps and paves the way for future research in this subject area.

This paper fills the gap in the existing literature by comprehensively reviewing the articles on major factors impacting stock market volatility highlighting the theoretical relationship and empirical results.

The purpose of this paper is to analyze different seasonal anomalies for the Israeli securities markets for the pre- and post-global financial crisis periods.

The closing values of six indices of the Tel Aviv Stock Exchange (TASE) of Israel have been considered. The time frame ranges from 2000 to 2018. Further, the overall time frame has been segregated into pre- and post-financial crisis periods. The study employs dummy variable regression technique for assessing different calendar anomalies.

The results show evidence pertaining to different seasonal anomalies for the Israeli markets. The results specifically show that the anomalies change considerably across the pre- and post-financial crisis periods. The results are more apparent for three anomalies including the day of the week effect, the month of the year effect and the holiday effect. However, anomalies including the Halloween effect and the trading month effect are found to be insignificant across both pre- and post-financial crisis periods.

The study is first of its kind that analyzes different seasonal anomalies across pre- and post-financial crisis periods for the Israeli markets. The study provides newer insights about the overall return patterns observed in different indices of the TASE.

The purpose of this paper is to use financial market prices formed in betting markets as a measure of uncertainty of outcome and other factors as it relates to hockey attendance in three top European leagues, the KHL, SHL, and Liiga. This is the first study of European hockey to use betting market odds to estimate the impact of home team win probability and uncertainty of outcome on attendance.

The design of this study is a multivariate regression model with log of attendance and percentage of arena capacity as dependent variables in two separate regressions. Controlling for other factors, the role of the home team win probability and its square are explored for individual game attendance.

Fans of the KHL and SHL are found to prefer to see their home team win, but also exhibit strong preferences for uncertainty of outcome. Fans of Liiga prefer to see the home team win, but do not exhibit as strong a preference for uncertainty of outcome. This differs from recent findings in the sport of baseball and from previous findings for the NHL.

Having a competitive league is not only important for television ratings, but also for in-person attendance in these European hockey leagues. Importance of uncertainty of outcome varies across leagues.

The paper uses financial market prices, betting market odds, as a measure of game expectations (home team win probability) and uncertainty of outcome and applies it to a new setting for three of the top European hockey leagues. The findings illustrate that uncertainty of outcome is important for the KHL and SHL, but statistically insignificant for Liiga.

As digital technologies expand access to new forms of legalized gambling, including sports betting and online gaming, it is important to assess the impact of macroeconomic and equity market outcomes on fund flows into gambling. The authors’ findings will be of interest to policymakers and the gambling industry, as various forms of gambling, including day trading, gain broad public acceptance.

The authors examine the impact of macroeconomic forces, business cycles, and financial market wealth on gambling. The authors propose a nonlinear model linking aggregate gambling expenditures to macroeconomic, stock market, and gambling industry variables. The authors estimate the proposed model using nonlinear estimation procedures.

The authors find that price of wagering, incomes, and supply of gambling opportunities are the primary determinants of wagering demand. Aggregate wagering is negatively impacted by realized stock returns and market volatility, but rises during recessions.

To the best of the authors’ knowledge, the questions posed and addressed in this manuscript have not been addressed in prior literature.

Horse racing occupies a significant but separate part of sports gambling provision. The historical importance of horse breeding as well as employment effects have been used to justify the necessity of betting revenue in the horse sector. In the Nordic countries, these arguments are used to organise horse racing separately from other sports betting. In this context, horse racing, and particularly trotting, remains a lucrative sector for horse owners and producers of racing. The current study focuses on the production chains and financial interests behind horse racing in the Nordic countries. We use financial statements and annual reporting of Finnish, Norwegian and Swedish horse betting companies to determine who benefits financially from racing, what kind of production-related interests are involved and whether horse racing produces surplus to societies or merely maintains its own function. The results are discussed in light of the intertwined organisation of horse racing in the Nordics and the role of horses and animal welfare in the production of racing.

This paper aims to examine how hybrid business models can help companies to survive in a constantly evolving digital world. The hybridization of business models is a promising approach to innovation.

The authors discuss the key elements of a successful business model hybridization along the Business Model Canvas (Osterwalder and Pigneur, 2010). In particular, the elements of value propositions, customer segments, channels and a company’s cost structures demonstrate the individual steps toward a hybridized business model. Using Paddy Power Betfair as an example, the authors showcase how the concept of a hybrid business model can be successfully implemented in practice.

By hybridizing its business model, Betfair not only expanded existing customer value propositions but also introduced new ways of co-creating value with customers. Simultaneously, the hybridization positively affects a company’s revenue model, hence evolving in new ways of capturing value.

To effectively hybridize and thus innovate a company’s business model, the two key factors are successful value creation and value capture. By hybridizing elements of existing business models, new value for customers can be generated. Companies capturing this additional value may achieve sustainable and successful business models and thereby gain a competitive advantage.

Analyzing how the post-Soviet transition interacts with the crisis of market finance exhibits a new “greed-based economic system” in the making. Asset grabbing is at its core and hinders capital accumulation. All the various privatization schemes have triggered off asset grabbing, asset stripping, and asset tunneling. A global contagion of such behavior has spread the power and cohesion of managers/shareholders (oligarchs) worldwide. Financial asset grabbing is less straightforward, though much widespread, and operates in financial markets through new financial products, securitization, firms buying their own shares, hedge funds, stock price manipulation, short selling, and the distribution of stock options.Shadow banking, and more generally a global informal economy, results from grabbing strategies in financial markets that breach the formal rules of capitalism. In alleviating and circumventing the rules, the oligarchy paves the way for economic malpractices and crime, calling capitalist laws into question.In such context, systemic greed underlies unconstrained maximization of relative wealth, for which asset grabbing is a rational means, in a winner-take-all economy. At the present stage of our research, a greed-based economy cannot yet be theoretically defined as a transition either to a new phase of capitalism or to another different system.
