Abstract
A partial equilibrium, duality-based empirical model is used to measure the tariff and nontariff
barrier effects on fresh tomato prices, quantities, and labour demand in Florida, USA, and Sinaloa, Mexico.
Reduced-form estimates indicate that the US unit tariff has increased agricultural labour demand in Florida while
reducing field labour demand in Mexico. Nontari:ff barriers have had a less significant impact on labour demand.
Product heterogeneity may account for varying nontariff barrier impacts on fresh tomato supplies and derived labour
demand. Linkages between Mexican agricultural labour supply and Florida agricultural labour demand require
further analysis.
