Casino games are games of chance with a built-in house edge. No strategy, system or timing changes the odds in the player’s favor over time, and most players lose money over time. Nobody should gamble money they cannot afford to lose, and anyone struggling with gambling can contact a local support service. This article sets out the economic arguments that supporters make for casinos and explains what would be needed to judge them. It gives no figures, because any numbers would depend on a particular place and period.
Where the money comes from
An economic argument starts with a simple fact. When people play casino games, they are paying for an entertainment product, and on average that cost equals the house edge multiplied by the amount wagered. The amount a venue retains after paying winnings, discussed under hold percentage, is its revenue. Everything else in the economic story flows from that revenue: wages, supplier payments, profits and taxes.
So the real question is not whether a casino generates money for its owners and staff, which it clearly does when it operates. The question is whether the activity makes a community or country better off overall, compared with what would have happened otherwise. That is harder to answer.
The arguments usually made in favor
Employment. Casinos need dealers, machine technicians, security staff, surveillance operators, hospitality workers, cooks, cleaners and managers. Supporters point to these jobs, plus indirect jobs at suppliers, construction firms and nearby businesses. Large resorts with hotels, restaurants and entertainment venues can employ a broad range of workers.
Tax revenue. Governments may tax operators and use the proceeds for public services. The mechanisms are described in the general overview of operator taxation. Supporters argue that this revenue funds services without raising other taxes, or that gambling is a voluntary way to raise it.
Tourism and visitor spending. A casino can attract visitors who also spend on hotels, meals, transport and shopping. This idea underlies much of the thinking behind destination gambling, and it is the strongest in places where most players come from elsewhere.
Investment and development. Building a casino can involve construction, infrastructure upgrades and new commercial activity in an area. Supporters sometimes argue that a casino can revive a declining area or anchor wider development.
Supplier and technology industries. Game design, software, testing and equipment manufacturing form their own sector, described in the pieces on the game development process and industry technology.
Moving spending into regulated channels. Some argue that a licensed industry captures money that would otherwise be spent on unlicensed gambling, bringing it under oversight and taxation. Whether this happens in practice depends on how the legal market compares with illegal alternatives.
Why a claimed benefit is not a net benefit
Each argument above deserves a second question. Economists generally distinguish between gross effects, which count what a casino adds, and net effects, which subtract what it displaces or costs. Several issues come up.
- Substitution. If local residents spend money at a casino that they would otherwise have spent at local restaurants, shops or cinemas, then casino revenue partly replaces other businesses’ revenue rather than adding to it. The more of the casino’s customers come from outside the area, the less this matters.
- Where profits go. If the owners live elsewhere, a share of the profit may leave the local economy. Wages and local purchases stay, but the profit may not.
- Job quality and displacement. The number of jobs is one measure. Wages, hours, stability and whether workers were previously unemployed or moved from other jobs are others.
- Opportunity cost. The land, capital and public support used for a casino could have gone to something else. A fair comparison asks what the alternative would have produced.
- Social costs. Gambling harm has costs for individuals, families and public services, which are described in the discussion of gambling harm and problem gambling. A complete accounting would weigh them against the benefits, though they are hard to measure.
- Reliance on losses. Casino revenue comes from player losses in aggregate, and the share of that coming from people who gamble heavily or harmfully is a matter of continuing debate. Revenue that is concentrated among a small number of heavy players raises ethical questions that a revenue total does not show.
What evidence would be needed
To judge whether a casino delivers net economic benefits in a place, one would want data that is rarely simple to obtain:
- The origin of customers, to see how much spending is new to the area and how much is diverted from elsewhere.
- Employment records before and after opening, including who was hired, their previous status and wages, and the effect on other local businesses.
- Actual tax receipts and how they were used, compared with projections made before opening.
- Data on changes in gambling-related harm, such as use of support services, and the costs borne by public services.
- A credible comparison with similar places that did not open a casino, so that general economic trends are not mistaken for the effect of the casino.
Without comparisons of this kind, before-and-after claims can be misleading, since local economies change for many reasons at once.
Forecasts and results
Projections made when a casino is proposed come from the people with the most interest in the outcome, whether developers hoping for approval or officials hoping for revenue. That does not make them wrong, but it is a reason to look for independent assessments and, later, for evidence on what actually happened. The same caution applies to critics’ claims. Both sides can pick favorable examples.
Markets can also change. A casino that is novel in a region can attract many visitors at first, while later competition from other venues or from online casinos may spread the same spending among more providers, so early results may not persist.
A balanced reading
The reasonable conclusion is limited. Casinos do create jobs and can generate tax revenue, and some places have chosen to host them for those reasons. Whether the net gain is large, small or negative depends on local conditions: who the customers are, how the industry is taxed, what the alternatives were and how the social costs are handled. The effect on residents is considered separately in the discussion of community impact, and for the individual player the economics are simple: the games have a negative expected result, so entertainment spending on them should be limited to money that is truly spare.
