It is believed that changes in the varieties of an imported product might have effects on the import price index for the product that are similar to the effects of new goods on the cost of living. Recently, a new index number formula that incorporates the effects of new goods has been suggested...

Recently Acemolgu, Aghion, Bursztyn and Hemous (AER 2012) formulated a model in which a high macroeconomic elasticity of substitution between clean and dirty production represents a crucial condition for green growth. Until now it has never been systematically estimated. Using a novel panel of...

Most studies in Vietnam use the Cobb-Douglas production function and its modifications for economic analysis. Extremely rigid presumptions are a main weak point of this functional form, particularly if the elasticity of factor substitution (ES) is equal to one, which hides the role of the ES for...

<Para ID="Par1">Despite substantial interest in the role of energy in the economy, the degree of substitutability between energy and other production inputs and the way energy should be included in the production function remain unresolved issues. This study provides industry-level parameter estimates of...</para>

By defining the Variable Output Elasticities Cobb-Douglas function, this article shows that a large class of production functions can be approximated by a Cobb-Douglas function with nonconstant output elasticity. Compared to standard flexible functions such as the Translog function, this...

A distribuição funcional da renda, com todas as suas implicações para a distribuição pessoal da renda, tem sido pouco avaliada, principalmente devido à falta de informações. Este trabalho busca, inicialmente, descrever a evolução dessa distribuição funcional da renda, sob o ponto de...

Estimation of the non-linear Constant Elasticity of Scale (CES) function is generally considered problematic due to convergence problems and unstable and/or meaningless results. These problems often arise from a non-smooth objective function with large flat areas, the discontinuity of the CES...

Despite substantial interest in the role of energy in the economy, the degree of substitutability between energy and other production inputs, and the way energy should be included in the production function remain unresolved issues. Our study provides industry-level parameter estimates of...
