我们分析了由领先地区和落后地区组成的总体经济中的空间溢出效应，其中溢出效应源于当地公共产品的提供。具体来说，如果领先地区提供公共物品，那么落后地区就会获得一些溢出效益，反之亦然。我们首先求解当公共投资决策同时进行时两个地区地方公共产品的纳什均衡水平；接下来，我们确定每个地区的均衡福利水平。其次，假设公共投资决策是集中的，我们计算了使总福利最大化的地方公共产品的水平。最后，我们描述了一种区域间转移计划，该计划导致每个区域在纳什均衡中非合作地选择与总福利最大化时出现的公共投资水平相同的公共投资水平。
We analyze spatial spillovers in an aggregate economy consisting of a leading and a lagging region where the spillovers stem from the provision of a local public good. Specifically, if the leading region provides the public good then the lagging region obtains some spillover benefits and vice versa. We first solve for the Nash equilibrium levels of the local public goods in the two regions when public investment decisions are simultaneous; next, we determine the equilibrium welfare levels in each region. Second, on the assumption that the public investment decisions are centralized, we compute the levels of the local public goods that maximize aggregate welfare. Finally, we describe an interregional transfer scheme that leads each region to choose non-cooperatively in a Nash equilibrium the same public investment levels as those that arise when aggregate welfare is maximized.
