Authors argue the temperature-effect (TE) and fixed-effect (FE) specifications are the correct, less-downward-biased estimates; OLS-without-temperature is biased || 'coefficients of price controlled temperature effect (TE model) or fixed effect model (FE model) are larger and more significant in total, residential, commercial demand ... estimating price elasticity of electricity demand in South Korea is downward biased' (Abstract/Conclusion, p.219/226)
