The gas price brake increases gas prices: Empirical evidence
研究德国在俄乌冲突后实施的天然气价格补贴政策，发现该政策反而使德国天然气总成本上升，主要原因是现有供应商将价格提高了高达90%。
In the aftermath of the Russian invasion in Ukraine and rising gas prices, the ’gas price brake’, a subsidy scheme for retail consumers and firms, was implemented in Germany. We employ a difference-in-differences approach and analyze data on offered gas contracts from two countries with comparable gas markets, where one country (Germany) has implemented the gas price brake and the other (Austria) has not. We find that the gas price brake led to an increase in total annual gas costs in Germany. This increase is entirely attributable to incumbents increasing counterfactual gas prices by up to 90%. Non-incumbents do not ’milk‘ the brake.
