Transport Infrastructure Investment and Interindustry Spillovers: The Effects on the Cost Structure of Australian Industries

No 2014-24, Discussion Papers from School of Economics, The University of New South Wales

Abstract: This paper examines the impact of the provision of public transport infrastructure on the cost structure of the Australian economy within a context that recognises industry agglomeration externalities. The paper extends the symmetric generalised quadratic cost functionby incorporating public transportation capital as an external input and adapting the spatial econometric techniques to an industrial context to allow for industry spillovers in the cost analysis. Using industry level data over the period 1990-2010, the paper finds that while public transport has a productive effect in reducing the cost of production, neglecting interindustry spillovers has noticeably overestimates this effect.
