Spillovers and the Locational Effects of Public Infrastructure
研究了公共基础设施投资可能产生的负面产出溢出效应，发现加州各县的高速公路资本增加会吸引其他县的生产要素流入，导致后者产出下降。
This paper examines the possibility of negative output spillovers frompublic infrastructure. A model of productive public capital shows that when input factors aremobile, public infrastructure investments in one location can draw production away from otherlocations. In a linear production‐function framework, this effect would be manifested as anegative output spillover from public capital. Using data for California counties from 1969through 1988, such negative spillover effects are shown to exist in the case ofstreet‐and‐highway capital. The data show that changes in county output are positivelyassociated with changes in street‐and‐highway capital within the same county, but outputchanges are negatively associated with changes in street‐and‐highway capital in other counties.
