The betting industry has been transformed by the Internet. Growth of person-to-person betting, mediated through online betting exchanges, has been a key element of this transformation. Betting exchanges enable traders to either back (buy) or lay (sell) bets on a wide range of sporting events. Such continuously operating online betting markets have ensured the transition of the use of high-frequency data (sub-daily sampling) from the financial setting into the betting market context. This chapter reviews recent academic research on the topic of information efficiency in high-frequency, in-play football betting markets. Several studies have reported evidence violating weak-form information efficiency, in the form of a favorite-longshot bias in in-play betting prices. However, there is evidence in the literature in favor of semi-strong form information efficiency. One study reports interesting evidence in support of strong-form information efficiency. As in-play betting markets continue to develop, driven by further improvements in computing power, parallel growth is anticipated in research on information transfer and price formation in financial markets, an exciting new arena for academic study.

Sports betting markets have attracted a fair amount of research over the years. For association football, most of this research has focused on predicting the outcome of single matches and hence on the evaluating the efficiency of the match results betting markets. This paper presents a study on the betting market for league winners, a market that operates for almost a full year and therefore operates under different conditions than the relatively short-lived match results markets. Attempts are made to analyze both weak and semi-strong forms of information efficiency. Although the results are mixed, there are some indications that the market is inefficient with respect to both forms of information.

This chapter evaluates the record of media forecasters in selecting winners, with returns judged against the benchmark of information efficiency as specified in the efficient-market hypothesis, updating in particular prior analyses of the well-established Pricewise tipping column in the industry newspaper the Racing Post with a new and bigger dataset. Most notably, the analysis seeks to establish whether or not the feature’s previously impressive record had been maintained and to exploit new market information sources which permit insights into the dynamics of horse race betting markets over time to reveal the extent of arbitrage opportunities with respect to the Pricewise selections. This is used to permit a more comprehensive evaluation of the degree of information efficiency with respect to these “events.”

The Internet and social media are crucial platforms for health information. Factors such as the efficiency of online health information, the outcomes of seeking online health information and the awareness of reliable sources have become increasingly important for the elderly during the COVID-19 pandemic. This study aimed to examine differences between elderly individuals’ income above and below the average monthly wage in relation to their online health information efficiency and the outcomes of seeking online health information; to evaluate types of online information sources with online health information efficiency and the outcomes of seeking online health information; and to explore online health information efficiency as a mediator between health status and awareness of online sources. A cross-sectional study design was conducted with 336 elderly participants age 65 or older. The participants volunteered to complete a questionnaire. No differences were found between the two groups regarding efficiency in retrieving health information from official online health sites and Google. Perceived efficiency mediated health status and awareness of online sources. In these challenging times, it is important to provide a tailor-made education strategy plan for reliable sources of online health information for the elderly, in order to enhance their technology safety skills. It is also important to explore other mediating variables between health status and awareness of online sources.
