This paper uses a CES function to estimate the constant elasticity of substitution in consumption for non-tradables relative to tradables in a dependent economy framework. The methodology for generating data on real consumption of tradable and non-tradable goods, real prices of tradable and non-tradable goods and real absorption is based on the Bolivian Input-Output Matrix, producing quarterly data for the period 1990.1 to 2002.4. The data identify Bolivia as a country highly open to trade, with an average ratio of 55 percent in the value of exports and imports relative to GDP, non-tradable production accounting for 52 percent of GDP, and differences in the behavior of the internal and external real exchange rates. The HEGY test is used to identify and separate out seasonal unit roots in the data. A cointegration relationship was found between real absorption, the non-tradable to tradable consumption ratio and the non-tradable to tradable price ratio, suggesting inelasticity of substitution.
This paper's main goal is to estimate the elasticity of substitution of non-tradable goods, paying special attention to empirical problems related to time-varying parameters, missing regressors and model misspecification. To that end, the paper creates a database and estimates, via three alternative methods, quarterly series of consumption and prices of tradable and non-tradable goods for Uruguay ...

Export Pioneers in Latin America analyzes a series of case studies of successful new export activities throughout the region to learn how pioneers jump-start a virtuous process leading to economic transformation. The cases of blueberries in Argentina, avocados in Mexico, and aircraft in Brazil illustrate how an initially successful export activity did not stop with the discovery of a single viable ...

This paper develops a two-country, general equilibrium model of oligopoly in which the degree of horizontal product differentiation is endogenously determined by rms` strategic investments in product innovation. Consumers seek variety and product innovation is more skill intensive than production. Stronger import competition increases innovation incentives, and thereby the relative demand for skil ...
