摘要：
Coal heating in residential houses is an important source of outdoor and indoor air pollution in many countries. Switching to electric heating can greatly reduce air pollution and improve health. We conduct a field experiment to investigate channels of aversion to electric heating by sending 3 types of information containing either electricity cost, or health consequences of indoor coal heating, or social information on the heating methods adopted by others to households in rural villages in Northern China. We find that majority of households overestimate their electricity expense, and underestimate the health consequence of coal heating. We also find that, when households are given feedback on accurate electricity expense, the demand for electric heating decreases by 32 percent, and this effect is stronger for households who are concerned about the heating price, while it significantly increases the demand for electric heating for those who overestimate the energy cost. Providing information on the health consequences of coal heating increases the demand for electric heating by 15 percent, and the effect is more pronounced for those who are concerned about the health impact from coal heating, or underestimated the health consequences from coal heating. Moreover, providing social information on the heating methods chosen by others increases the demand for electric heating by 25 percent. The treatment effect of cost SMS, health SMS, and social SMS appears to be persistent even after 1 year. Overall, our results suggest that cost concern and underestimation of health consequences are the two main reasons for aversion to electric heating, and the latter can be mitigated by providing households with correct health information.
