Medición de la desigualdad en el sector de la construcción del Ecuador en el 2017 en escala de Gini.

Abstract

The main objective of this investigation is to measure the inequality of incomes of Ecuadorian construction sector in 2017. For this purpose, the relevant literature about Lorenz Curve and Coefficient of Gini was carefully studied. Furthermore, valuable information about construction sector was gotten from Superintendencia de Compañías, Valores y Seguros. On the other hand, the result of Lorenz Curve shows high level of inequality of the construction sector’s incomes distribution. Also, this information was corroborated at the moment of calculating the Gini Coefficient, which outcome was 0.642 in 2017. In addition, this result was compared with the result of Gini Coefficient of Ecuadorian construction sector in 2012 (0.546). It can conclude that incomes distribution was less inequality than now. Equally important was the comparison with the Spanish and Chilean construction sector’s incomes distribution. The outcome of Gini index was 0.368 and 0.813, respectively which means Ecuadorian construction sector is less inequality about incomes distribution than Chilean sector, but more inequality than Spanish sector. Finally, this investigation makes mention of the existence of an oligopolistic market, therefore, it is necessary that regulatory agencies must enforce laws that avoid inequities in the market that affect negatively to the micro-enterprise, small and medium-size enterprise of construction sector.
