That whether expansionary government spending crowds out private consumption is examined by evaluating the intra-temporal elasticity of substitution between them. Using annual data (1981–2000) of 23 OECD countries, a linear deterministic cointegration relation between private consumption, government spending and their relative price is supported. We have two findings: first, the panel estimators plausibly compute the parameter estimates in general. Second, when cross-sectional correlation is considered by using a SUR estimator, the statistical significance of panel cointegration is improved. Thirdly, the intra-temporal elasticity of substitution indicates that government and private consumption are found to be complements, which shows that expansionary government spending does not crowd out private consumption.
