Crowding-out and crowding-in effects of the components of government expenditure

We examine the effects of disaggregated government expenditure on investment using fixed- and random-effect methods. Using the government budget constraint, we explore the effects of tax- and debt-financed expenditure for the full sample, and for sub-samples of developed and developing countries. In general, tax-financed government expenditure crowds out more investment than debt-financed expenditure. Expenditure on social security and welfare reduces investment in all samples while expenditure on transport and communication induces private investment in developing countries.
