The case for stadium and event subsidies is a weak one. The economic arguments in favour of such subsidies do not succeed. Evidence from a variety of sources suggests that government support for stadiums and events is unlikely to contribute to economic growth. Furthermore, subsidies are often directed at pleasing special interests rather than promoting the overall welfare of residents.
Many of the arguments for subsidies postulate significant social benefits from the stadium or event, in excess of the private investment return. However, events and stadiums have recourse to multiple means of finance, including admission fees, corporate sponsorship and donations. All or most of the social benefits from the stadium or event can be captured or 'internalised' through these means. If individuals value the outputs of a stadium or event, markets are likely to find a way of realising the relevant gains from trade.
