Abstract The key result of the so-called "New Trade Theory" is that countries gain from falling trade costs by an increase in the number of varieties available to consumers. Though the number of varieties in a given country rises, many models predict that global variety decreases as imported varieties drive out local varieties. This is potentially worrisome when consumers care about non-exported foreign varieties either due to tourism (especially when foreign varieties are highly desired) or through an existence value (a common tool in environmental economics where simply knowing that a species exists provides utility). Since lowering trade costs induces additional varieties to export and drives out some non-exported varieties, these modifications result in welfare losses not accounted for in the existing literature. Nevertheless, it is only through the existence value that welfare falls as a result of declining trade barriers
