La teoría del consumidor: dualidad, elasticidades, restricciones de la demanda y bienestar
[Consumer theory: duality, elasticities, constraints of the demand and welfare]


  • Ávalos, Eloy


In this paper we explore the minimization of expenditure, less important theorems of this approach, which must be met given the conditions of the preferences and the budget set. We will study the conditions of constraints of the demand, relating them to the different elasticities of Marshallian and Hicksian demands. Finally we will discuss the analysis of consumer welfare when prices change.
