Heterogeneous household responses to energy price shocks
利用假设性能源价格冲击情景下的调查数据，研究能源需求价格弹性和支付能源账单后的边际消费倾向的非线性特征及家庭异质性，发现低收入家庭和计划装修的家庭弹性更高，而补贴比减税更有效。
We use survey evidence on reported spending in hypothetical energy price shock scenarios to study novel features of the price elasticity of energy demand and the marginal propensity to consume (MPC) after paying the energy bill. We document several nonlinearities depending on the sign and magnitude of the energy price shock that are economically relevant, including at the extensive and intensive margins. There is also considerable heterogeneity across households. For price increases, low-income families and those planning major home renovations over the next months report a higher price elasticity of energy demand. Conversely, households with more appetite to consume exhibit a lower elasticity. In contrast, MPCs depend on households’ income, saving buffer, financial uncertainty, appetite to consume, and gender of the household head. Yet household characteristics hardly matter when energy prices decline; we only find smaller MPCs for households with a greater saving buffer and younger families. Finally, we show that targeted price subsidies on energy for Belgian low-income households have been much more effective in supporting non-energy consumption than the general VAT reduction on energy prices.
