abstract="The importance of &quot;broader&quot; economic effects of transportation infrastructure has recently become apparent. &quot;Broader&quot; refers to impacts beyond the geographic boundaries within which the infrastructure investments are undertaken. Approaches to estimate &quot;broader&quot; impacts in production and cost function models are evaluated. A contribution of this paper is the empirical demonstration with a cross-section of US states' manufacturing data that ignoring broader effects of a spatially lagged dependent variable can lead to mis-statements of the overall productive impacts of public infrastructure. These inaccuracies can arise because of missing indirect effects and from specification bias that may directly impact the infrastructure elasticity.<p />",
