Government Spending in a Simple Model of Endogeneous Growth
扩展了内生增长模型，纳入税收资助的政府服务，分析其对生产或效用的影响，发现生产性政府支出先提高后降低增长率和储蓄率，而效用型支出则持续降低两者。
One strand of endogenous-growth models assumes constant returns to a broad concept of capital. I extend these models to include tax- financed government services that affect production or utility. Growth and saving rates fall with an increase in utility-type expenditures; the two rates rise initially with productive government expenditures but subsequently decline. With an income tax, the decentralized choices of growth and saving are "too low," but if the production function is Cobb-Douglas, the optimizing government still satisfies a natural condition for productive efficiency. Empirical evidence across countries supports some of the hypotheses about government and growth.
