Diversificación productiva y cambio estructural en economías cerradas y abiertas

Productive diversification has been the main determinant of structural change of the economies. This hypothesis is analysed for nine countries under a relatively closed trade regime, and for nine Latin American countries under a relatively open trade regime with the United States. The equations of structural change that are tested are derived from a multisector dynamic general equilibrium model. The negative impact of productive diversification on the relative allocation of resources to the primary sector cannot be rejected for closed economies: greater diversification increases the relative productivity of manufacturing activities. The impact of a country’s comparative advantages on the allocation of resources to agriculture cannot be rejected: the relative agricultural productivity has a positive impact; the relative capital endowment has a negative impact; and the real exchange rate has a positive impact. In the last case, it is argued that low diversification induces a deterioration in the terms of trade, which favours specialization in primary activities.
