For the provision of better social services, the health sector has been an important part of national strategy for reducing poverty and income disparities among different income groups in Pakistan. The distribution of access to and use of health among households has been a long-standing concern among policy makers. In this study, government health expenditure is treated as a fixed factor that influences household health behaviour, conditional on such factors as household income, education, and family size. The results of the study suggest that government health expenditure is associated with higher use of both preventive and curative health services by children. The results also indicate that increased government expenditure is actually associated with lower use of health services by the children of the poor, although this negative association is generally weak. However, if increased government spending improves health care opportunities for the nonpoor more than for the poor, the total effect of government spending on the health outcomes of the poor could be less even though they have a higher marginal product of health care inputs.
