Does gambling harm or benefit other industries? A systematic review.

The economic benefits of gambling may be offset by economic harm to other industries. This economic phenomenon, also known as substitution or cannibalization, refers to a new product that diverts consumption and profits from other products or industries. Gambling may displace revenue from other businesses, but economic impact studies on gambling do not consider such shifts between expenditures. This paper presents a systematic review of the available evidence (N = 118) on whether the introduction or expansion of gambling harms or benefits other business activity. Although the issue has been considered in previous review studies, no industry-level analysis is currently available. The results show that such an approach is necessary, as the impacts of gambling on other industries appear to depend strongly on the type of industry, as well as on the location and type of gambling. Industries that are negatively affected by gambling include other recreation, retail and merchandise, manufacturing, and agriculture and mining. Alcohol consumption, construction, and the finance, insurance, and real estate industries, as well as other services, appear to be positively affected by the presence of gambling. In other cases, the evidence is either mixed or inconclusive. These results nevertheless depend strongly on the type of gambling. Destination gambling appears to be more beneficial to other industries than recreational gambling. Overall, the results show that even in cases when gambling does substitute for other industries, the displacement is not complete. The reasons for this and the gaps in the existing evidence and literature are discussed
