Relationship between Health Expenditure and GDP in an Augmented Solow Growth Model for Pakistan: An Application of Co-integration and Error-Correction Modeling

Abstract

This paper examines the temporal interdependence between gross domestic product and health expenditure per capita for Pakistan in an augmented Solow growth model suggested by Mankiw, Romer and Weil (1992) for the period of 1973-2001. This paper is an extension of the MRW model by incorporating health capital proxied by health expenditure to the augmented Solow model. Moreover, an openness variable is also included in the model in order to capture the effect of technological changes on growth. The paper employs co-integration, ECM methodology and several diagnostic and specification tests. The empirical findings show a significant and positive relationship between GDP and Health Expenditure, both in the long- and short-run.
