We derive a method to econometrically estimate the tariff equivalent and foregone trade effects of a prohibitive technical barrier to trade (TBT) based on Wales and Woodland's Kuhn-Tucker approach to corner solutions in consumer choice. The method overcomes the lack of observed data on bilateral...

The price-wedge method yields a tariff-equivalent estimate of technical barriers to trade (TBT). An extension of this method accounts for imperfect substitution between domestic and imported goods and incorporates recent findings on trade costs. We explore the sensitivity of this revamped TBT...

Time delays due to inefficient customs and administrative procedures have become a leading non-tariff barrier (NTB) that restrict international trade and impair social welfare. This paper investigates how time delays affect product quality, product price, trade flow, and social welfare, using...
