Constructing a SAMEA to analyze energy and environmental policies in Chile

In this study, a social accounting matrix with environmental accounts (SAMEA) for Chile is built based on the 2016 input-output tables, socioeconomic household survey, expenditure survey, among other information sources. The SAMEA has high disaggregation of the electricity sector that is not currently available in national accounts. Complementary information on the operating costs of different electricity subsectors (thermoelectric, solar, wind, hydro, and biomass) from national and international studies are obtained. Then, intersectoral indicators, accounting multipliers, and simulations of shocks (subsidy on the non-conventional renewable energy subsectors and environmental taxes) are calculated. The main findings of the study show that each electricity subsector has different production technology and emission intensity. In consequence, energy and environmental policies simulated with intersectoral models that do not disaggregate the electricity sector would produce significant biases in the results.

Automated summary

The study builds a SAMEA for Chile based on various data sources, with a high disaggregation of the electricity sector. It highlights the importance of considering the different production technology and emission intensity of each electricity subsector in energy and environmental policy simulations, as using models that do not disaggregate the electricity sector could lead to significant biases in the results.
