This paper investigates the economic value of trade when prices of transportation services are endogenous to cross-market … price spreads. This is relevant for liquefied natural gas (LNG) exports. LNG transportation capacity is limited in the short … transportation costs and market integration. We use this method to quantify the effect of endogenous transportation costs on the …
