Economic Impacts, Value Added, and Benefits in Regional Project Analysis

This paper addresses five issues encountered when estimating secondary benefits in regional project analysis: (a) the correction for opportunity cost of factors used, (b) the treatment of mobile factors, (c) the effect of economies of size, (d) the role of forward linkages, and (e) the role of spatial structure of economic regions. The first four are reasons that only a small part, if any, of regional impacts can be treated as regional net benefits. The fifth is a reason that, when secondary benefits or damages do exist, their correct estimation can depend on the spatial structure of the affected areas.
