The “product” travel cost model (PTC) improves supply and substitution specification in travel cost
models (TCM), eliminating common biases in estimating welfare effects of qualitative changes at specific
sites. Angling sites and participation are modeled as a system of product supplies and demands; changes
in angling quality at specific sites...
