An economic growth which is wide-area scattered is one of the most important indicator
of social well-being and is such a strong factor that can induce long-range demographic
dynamics. Incoming migration fluxes are scattered across the national territory following patterns
that appear mostly relational rather than economically driven. The resulting effect can
be the well-known problem of Spatial Mismatch, SM. The institutionalist approaches permits
to use different scaled units of analysis, with different levels of integration but coexistent under
the very same historical-social pattern-determining context. This work will try to explain
the relationship between SM and the more general Transaction Costs. With this hypothesis it
will be possible to read from a (neo)institutionalist perspective the whole, empirical and theoretical,
body of Spatial Mismatch.
Trough the introduction of the temporal perspective the present work propose a theoretical
framework that shows that the increasing degree of spatial mismatch discussed in the
case study has appeared only when the redistributive action so important for the initial development,
and operated mainly trough the increasing of social capital stock, has declined. Therefore
upgrade policies of public goods are considered constantly needed in order to promote
growth itself
