Family size, increasing block tariff and economies of scale of household electricity consumption in Vietnam from 2010 to 2014

This paper uses data from Vietnam Household Living Standard Survey (VHLSS) in 2010, 2012 and 2014 to investigate whether there are economies of scale for Vietnam household electricity consumption in that period. The data will be tested formally by an OLS model and checked robustness by visualization of local linear regressions.
