The Pass-Through of Minimum Wages into U.S. Retail Prices: Evidence from Supermarket Scanner Data
利用2001-2012年间美国各州最低工资上调事件和超市扫描数据,发现最低工资每提高10%,食品杂货价格平均上涨0.36%,且价格调整主要发生在立法通过后而非实施后,表明定价具有前瞻性。
Abstract This paper estimates the pass-through of minimum wage increases into the prices of U.S. grocery and drug stores. We use high-frequency scanner data and leverage a large number of state-level increases in minimum wages between 2001 and 2012. We find that a 10% minimum wage hike translates into a 0.36% increase in the prices of grocery products. This magnitude is consistent with a full pass-through of cost increases into consumer prices. We show that price adjustments occur mostly in the three months following the passage of minimum wage legislation rather than after implementation, suggesting that pricing of groceries is forward-looking.
