Title: Impact of Public Sector Investment on TFP in Agriculture in Punjab, Pakistan
Abstract: Agricultural productivity growth in underdeveloped countries is an important long-run source of real income growth and better living standards, and different sources of productivity have been identified in the empirical literature. In this study, we examine the relationship between productivity in agriculture and investments in agricultural research, extension, irrigation, and rural roads in Punjab province, Pakistan. Results show that agricultural research has a significant and positive impact on productivity with a long-run elasticity of 0.24; and the marginal internal rate of return to research is 27%. Public investments in agricultural extension, rural roads, and irrigation are also significant. Granger-causality tests show a unidirectional relationship from research to productivity.
