A two factor production function with a variable elasticity of substitution is considered. The note describes the relation between the elasticity and the behavior of the marginal products and the output per unit input as the factor ratio approaches zero or infinity.

We propose a set of comprehensive axioms that seek to capture our intuitive understanding of the properties of an emission-generating technology (EGT). We show that an EGT that satises these axioms can be parametrically represented by more than one implicit production function that are derived...

Cobb Douglas production function parameters are not identified from cross-section variation when inputs are perfectly flexible and chosen optimally, and input prices are common to all firms. We consider the role of adjustment costs for inputs in identifying these parameters in this context. The...

The formation of the European Union (EU) is the one of the biggest political – economic events of the last 50 years. The aim of this study is to develop EU economy functioning system dynamic model. Main research method is system dynamics. General scheme of EU economy system dynamic model is...

This paper provides a simple proof of the result that if a production function is homogeneous, displays non-increasing returns to scale, is increasing and quasiconcave, then it is concave. If the function is strictly quasiconcave or one-to-one, homogeneous, displays decreasing returns to scale...

This article proposes an identity regarding economic outcomes when producers maximize profits, with free entry and exit of firms. The identity links consumer and producer theory and leads to several results that contribute to understand what should -and should not- be expected under the...

En este documento se evalúa el desempeño del sector metalmecánico en Colombia,durante el período 1998-2007, utilizando técnicas de frontera estocástica (SFA)que, a través de la estimación de las desviaciones de una función ideal de costos,permiten medir los niveles de eficiencia...

The paper enumerates the factors that determine the production potential of the company, points out the references to the opinions of economic experts in terms of productive investment. The criteria are "inferred" and economically interpreted. Decision making is based on initial information, on...
