Decentralization tends to increase both total and subnational spending on public infrastructure.
Those services have been decentralized in many countries, and many others are rapidly decentralizing. The central government is still responsible for many other infrastructure services, such as power and telecommunications, but this too is changing as the responsibility is increasingly transferred to subnational governments. Recent technological innovations reduce the need for services to be provided by monopolistic utilities. Power generation and distribution can now be handled competitively by decentralized units, and parts of some local telephone monopolies will increasingly meet competition from wireless telephones and rival wireline systems. The outcome reflects the net outcome of opposing effects.
