A small, upper-middle-income country in Central America, Costa Rica has pursued a market-led development strategy since the debt crisis of the 1980s. Free trade zones (FTZs) aiming to attract foreign investment and diversify exports were a cornerstone of the strategy. The successful diversification of production and exports is the result of the country’s accumulation of social capabilities in the past, a highly effective institutional support structure, generous tax incentives, and specificities of time and location. While the Costa Rican experience shows that industrial hubs/FTZs can be important vehicles for the creation of dynamic comparative advantages, it also highlights that a focus on industrial hubs with insufficient attention to national productive capabilities exacerbates a dualistic production structure, and that generous tax incentives for foreign investors tighten the fiscal constraint significantly. Governments need an overarching development strategy that articulates the roles and interactions of industrial hubs and SMEs, providing integrated industrial policies and a level playing field for domestic and foreign producers.
