Non parametric study of the relationship between energy consumption, income and temperature

The main goal of this paper is to measure the efficiency in converting energy use in people’s earnings for some Rio de Janeiro municipalities, Brazil. We used CCR and BCC classical Data Envelopment Analysis (DEA) models, with one input (per capita energy use) and two outputs (average temperature and average monthly earnings). The results indicate that municipalities with higher GDP values have lower efficiency. When discussing the results, we present possible reasons for this fact.
