On the contribution of reconstruction labor wages and material prices to demand surge
Anna H. Olsen, Keith A. Porter
2011, SESM 11-1
Demand surge is understood to be a socio-economic phenomenon of large-scale natural disasters, most commonly explained by higher repair costs (after a large- versus small-scale disaster) resulting from higher material prices and labor wages. This study tests this explanation by developing quantitative models for the cost change of sets, or...
