Menu Costs
Menu costs are the costs and frictions of changing prices. Currency Chaos in Argentina (Summer School) explains the concept through Neo Tango, a tango shoe store in Argentina that repeatedly changed prices as the peso moved and imported input costs rose.
The episode broadens menu costs beyond printing new labels. Sebastian Galiani says frequent price changes hurt competition because consumers cannot reliably know which store is cheaper. In very volatile economies, some markets can disappear because sellers do not know what price is safe to charge.
Key Claims
- High inflation makes price updating a recurring operational task.
- Constant repricing weakens consumer comparison and therefore price competition.
- Imported inputs intensify menu costs when currency depreciation changes replacement cost.
- Sellers may stop selling if the risk of charging the wrong price becomes too high.
- Menu costs are one channel through which Monetary Volatility damages real market functioning.
