Aggregation Problems in Estimates of Armington Elasticities and Pass-Through Effects

This article examines the level of aggregation problem for which Armington price elasticity of substitution and pass-through effects are usually estimated. On the basis of U.S. import data from 1995 to 2004 of wood products from Brazil and Mexico, it is argued that the usuallevels of aggregation used in the estimates for the elasticity of substitution are too high, since they tend to aggregate perfectly elastic products together with products whose elasticities vary from zero to any negative number. Analogously, the elasticity of relative prices with respect to the exchange rate, a measure of the pass-through effect, tends to be underestimated in the U.S. by the presence of homogeneous products whose prices are set in dollars and tend to equalize through arbitrage. Therefore, pricing-to-market estimates may be grossly overestimated for some industries in the U.S.Homogeneous Products, Differentiated Product, Pass-Through, Pricing-to-Market, Law of One Price

Validation of the Portuguese Version of the Healthy Lifestyle Questionnaire

The main objective of this study was the validation of the Healthy Lifestyle Questionnaire (EVS II), using a confirmatory factorial analysis of the measurement model, with veteran athletes. A total of 348 veteran Portuguese athletes of both genders, aged between 30 and 60 years (M = 41.64, SD = 9.83), of whom 200 were males and 148 were females, from several sports. The results of the confirmatory factor analysis demonstrate the adequacy of the adapted version of the EVS II, as the factorial structure (6 factors/24 items) has acceptable validity indexes: χ2 = 305.925, p = 0.000, df = 120.017, χ2/df = 2.549, NFI (Normed Fit Index) = 0.909, TLI (Tucker Lewis Index) = 0.918, CFI (Comparative Fit Index) = 0.944, GFI (Goodness of Fit Index) = 0.944, AGFI (Adjusted Goodness of Fit Index) = 0.909, SRMR (Standardized Root Mean Square Residual) = 0.048, RMSEA (Root Mean Square of Approximation) = 0.060, allowing evaluation of the dimensions of balanced diet, respect for mealtime, tobacco and alcohol consumption, other drugs consumption and resting habits. The adaptation to sport of the Portuguese version of EVS II can be used with reasonable confidence in the evaluation of healthy lifestyles in the context of sportinfo:eu-repo/semantics/publishedVersio

Latin American Export Specialization and Growth: An Inquiry into the Nature of Product Competition between Different Exporters

Given Latin America general specialization in resource-based products, this paper focus on the question as to whether or not it is possible for a country specialized in resource-based products to have high rates of export and growth. To do that, an attempt is made to develop and apply a new taxonomy to a sample of resource-based products exported by Latin American countries to the US. This taxonomy is based on the role played by prices in the mechanism through which countries compete in specific international product markets. Resource-based products are then classified as homogeneous, differentiated or highly-differentiated goods. The paper argues that exports of countries specialized in differentiated or highly-differentiated goods tend to be much more dynamic than of those specialized in homogeneous goods.Trade specialization, Export growth, Resource-based goods, Law of one price, Homogeneous goods and differentiated goods
