Unit Sales and Price Effects of Preannounced Consumption Tax Reforms: Micro-level Evidence from European VAT
利用微观产品数据，研究了消费税变化对耐用品价格和单位销量的影响，发现税率变动完全传导至价格，预期税率上调导致实施前销量暂时上升，但随后被抵消，永久效应使销量下降约2%。
We study the effects of consumption tax changes on prices and unit sales of durables utilizing micro-level product data. The results show that tax rate changes are fully shifted into prices. An anticipated tax rate change causes a temporary shift in unit sales shortly before implementation, which is more than offset by adjustments upon and after implementation. If the tax rate increases by 1 percentage point, unit sales rise by 2.5 percent on average in the last month before implementation. The permanent effect is a drop in sales by 2 percent below their original level, implying relatively strong intertemporal substitution effects.
