Elevator pitch

Private charitable contributions play an essential role in most economies. From a policy perspective, there is concern that comprehensive government spending might crowd out private charitable donations. If perfect crowding out occurs, then every dollar spent by the government will lead to a one-for-one decrease in private spending, leaving the total level of welfare unaltered. Understanding the magnitude and the causes of crowding out is crucial from a policy perspective, as crowding out represents a hidden cost to public spending and can thus have significant consequences for government policies toward public welfare provision.

Public expenditure and giving

Key findings


If people are only concerned with the total level of welfare provided, they will treat government spending as a perfect substitute for their own donations.

Crowding-out behavior is observed in laboratory experiments, which show that tax-financed contributions largely crowd out individuals’ charitable contributions.

Even if crowding out is small, potential negative consequences of a reduction in private philanthropy must be considered.


The decision to contribute privately is determined by many other factors beyond the total level of welfare, such as the individual’s desire for earning respect or social prestige, the utility derived from the act of giving itself, or the expected success of giving.

Apart from the laboratory setting, there is hardly any empirical evidence to suggest that government spending largely crowds out individual charitable behavior.

Studies based on micro-level data from charities or donors as well as studies using regional or cross-country variation in private and public spending usually find small or incomplete crowding-out effects, or even some evidence of a crowding-in effect.

Author's main message

The empirical evidence investigating whether public spending crowds out private charitable donations is mixed. A number of studies find significant but small crowding-out effects, while others find no effects or even evidence of a crowding-in effect. Hence, while crowding out might exist, it is far from being perfect. Policymakers should therefore acknowledge that their own expenditure on social welfare influences private spending. However, they should not be too concerned that an increase in government spending will largely crowd out private contributions of time and money.
