The indirect effects of highway investment.

Gwilliam K. M. (1970) The indirect effects of highway investment, Reg. Studies 4, 167–176. Both in the context of developed and developing economies there has been controversy concerning the way in which the indirect or secondary effects of road investment should be handled. This paper reviews some recent contributions to the discussion and examines the theoretical basis for including indirect effects in the project appraisal scheme. The role of impact studies in producing the relevant basic data is discussed. The paper concludes with some suggestions concerning the way in which consideration of re-organization effects might be introduced into the appraisal without abandoning the present established general form.
