Regional valuation of infrastructure improvements. The case of Swedish road freight
Erik Bergkvist ()
and Lars Westin ()
Abstract: Is it possible to identify regional differences among
shippers in their valuation of infrastructure improvements? The question is
analysed within a random utility approach where parameters are estimated by
a logit model. Data consists of a Swedish stated preference study from
1992. The results indicate that regional differences may exist but a
considerable heterogeneity in the empirical material prohibit robust
results in some cases. However, regional differences seem to exist when
industrial mix, shipping distance and goods values are held constant.
Independent of the limitations, the results should render implications to
any infrastructure benefit analysis where parameters from spatial averages
are used. The results are based on short term decisions and one should
recognise that parameters may vary under mid- and long- term.
