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.

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...

The aim of this article is to underline the development of the Evolutionary Theory starting from the original book of Nelson and Winter [1982]. This book is inspired by the Shumpeterian and Simonian traditions even if these authors are abandoning some of their core hypothesises. Nelson and...

We analyse the contribution of land to production activity for Japanese manufacturing industries employing panel data of the firms. Since land is not necessarily held for production purpose, we check the concavity of the cost function to see whether production is conducted efficiently.

Distinguishing between intended ("good") production and unintended or residual ("bad") generation, we introduce the concept of by-production. In by-production technologies, pollution is an output that satises a "costly disposability" assumption and violates standard free disposability with...

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...

Este trabajo contrasta la hipótesis de que, en la ciudad de Santa Cruz de la Sierra (Bolivia), las empresas continúan concentradas de forma monocéntrica. Para ello se estima un modelo estadístico que compara densidades locales para contrastar la hipótesis monocéntrica. Los índices de...
