PRODUCTIVE GOVERNMENT EXPENDITURE AND ECONOMIC GROWTH
综述了生产性政府支出与经济增长关系的最新文献，指出政策建议常依赖临界假设，建议未来研究关注基于思想的内生增长模型及未探索的政府支出类型。
Abstract We provide a comprehensive survey of the recent literature on the link between productive government expenditure and economic growth. We show that an understanding of the core results and the ensuing contributions can be gained from the study of their respective Euler equations. We argue that the existing literature incorporates many relevant aspects; however, policy recommendations tend to hinge on several knife‐edge assumptions. Therefore, future research ought to focus more on idea‐based endogenous growth models to check the robustness of policy recommendations. Moreover, the inclusion of hitherto unexplored types of government expenditure, e.g. on the ‘rule of law’, would be desirable.
