This study aimed at examining the relationship between public spending and economic growth and how the composition of government expenditure affects economic growth in Kenya using time series data from 1980 to 2014. To achieve the objectives, modified Granger causality and Autoregressive Distributed Lag model (ARDL) were used. The results revealed both short term and long term causality from economic growth to government expenditure but only short run causality from government expenditure to economic growth. Based on the economic classification, the long run ARDL regression results showed development expenditure promotes economic growth while government purchases have no significant effect on GDP. Other control variables such as inflation and unemployment had negative effect on economic growth. In terms of functional classification, the regression results showed that expenditure on education and infrastructure are important drivers of economic growth. The positive effect of health expenditure was not significant. Further, the regression results indicated that domestic savings and trade openness had significant positive effect on economic growth. Based on the empirical findings this study therefore recommends resources to be directed towards financing public infrastructure investment to improve economic performance. The study also recommends increasing resource allocation in the education sector to improve efficiency and support skills and human capital development that are important in promoting economic growth through increases in labor productivity. The study also recommends policymakers to enhance domestic resource mobilization and pursue favorable trade policies aimed at fostering robust economic growth.
