Post-Pandemic Price Flexibility in the U.S.: Evidence and Implications for Price Setting Models

Using the micro data underlying the U.S. CPI, we document several findings about firm price-setting behavior during and following the Covid-19 pandemic, a period with the highest levels of inflation seen in around forty years. 1) The frequency of price change increased substantially as inflation took off, and has declined markedly as inflation has receded. 2) The average size of price changes also increased as price increases became more common, while the absolute value changed little. 3) The dispersion of price changes did not fall, contrary to the prediction of state-dependent models. 4) A ...

Embedded Supervision: How to Build Regulation into Blockchain Finance

The spread of distributed ledger technology (DLT) in finance could help to improve the efficiency and quality of supervision. This paper makes the case for embedded supervision, i.e., a regulatory framework that provides for compliance in tokenized markets to be automatically monitored by reading the market?s ledger, thus reducing the need for firms to actively collect, verify and deliver data. After sketching out a design for such schemes, the paper explores the conditions under which distributed ledger data might be used to monitor compliance. To this end, a decentralized market is modelled ...

Stressed, not frozen: the Federal Funds market in the financial crisis

We examine the importance of liquidity hoarding and counterparty risk in the U.S. overnight interbank market during the financial crisis of 2008. Our findings suggest that counterparty risk plays a larger role than does liquidity hoarding: the day after Lehman Brothers? bankruptcy, loan terms become more sensitive to borrower characteristics. In particular, poorly performing large banks see an increase in spreads of 25 basis points, but are borrowing 1 percent less, on average. Worse performing banks do not hoard liquidity. While the interbank market does not freeze entirely, it does not seem ...

The pricing of FX forward contracts: micro evidence from banks’ dollar hedging

We use transaction-level data on foreign exchange (FX) forward contracts for the period 2014 through 2016 in conjunction with supervisory balance sheet information to study the drivers of banks? dollar hedging costs. Comparing contracts of the same maturity that are initiated during the same hour of the same day, we find large heterogeneity in banks? hedging costs. We show that these costs (i) are higher for banks with a larger FX funding gap, (ii) depend on banks? FX funding composition in terms of the source (interbank versus retail) and rollover structure (long-term versus short-term), ...

Macroeconomic Implications of Uniform Pricing

We compile a new database of grocery prices in Argentina. We find uniform pricing both within and across regions—i.e., prices almost do not vary within stores of a chain. In line with uniform pricing, prices in stores of chains operating in one region react to changes in regional employment, while prices in multi-region chains do not. Using a quantitative regional model with multi-region firms and uniform pricing, we find a one-half smaller elasticity of prices to a regional than an aggregate shock. This result highlights that some caution may be necessary when using regional shocks to ...

Accounting for persistence and volatility of good-level real exchange rates: the role of sticky information

Volatile and persistent real exchange rates are observed not only in aggregate series but also on the individual good level data. Kehoe and Midrigan (2007) recently showed that, under a standard assumption on nominal price stickiness, empirical frequencies of micro price adjustment cannot replicate the time-series properties of the law-of-one-price deviations. We extend their sticky price model by combining good specific price adjustment with information stickiness in the sense of Mankiw and Reis (2002). Under a reasonable assumption on the money growth process, we show that the model fully ...

Relative price dispersion: evidence and theory

REVISED: 8/1/18: We use a large data set on retail pricing to document that a sizable portion of the cross-sectional variation in the price at which the same good trades in the same period and in the same market is due to the fact that stores that are, on average, equally expensive set persistently different prices for the same good. We refer to this phenomenon as relative price dispersion. We argue that relative price dispersion stems from sellers? attempts to discriminate between high-valuation buyers who need to make all of their purchases in the same store and low-valuation buyers who are ...

What is the Value of Being a Superhost?

We construct a search model where sellers post prices and produce goods of unknown quality. A match reveals the quality of the seller. Buyers rate sellers based on quality. We show that unrated sellers charge a low price to attract buyers and that highly rated sellers post a high price and sell with a higher probability than unrated sellers. We fi nd that welfare is higher with a ratings system. Using data on Airbnb rentals, we show that Superhosts and hosts with high ratings: 1) charge higher prices, 2) have a higher occupancy rate and 3) higher revenue than average hosts.

Who bears the cost of a change in the exchange rate? The case of imported beer

This paper quantifies the welfare effects of a change in the nominal exchange rate using the example of the beer market. I estimate a structural econometric model that makes it possible to compute manufacturers' and retailers' pass-through of a nominal exchange-rate change, without observing wholesale prices or firms' marginal costs. I conduct counterfactual experiments to quantify how the change affects domestic and foreign firms' profits and domestic consumer welfare. The counterfactual experiments show that foreign manufacturers bear more of the cost of an exchange-rate change than do ...

Macroeconomic Implications of Uniform Pricing

We compile a new database of grocery prices in Argentina, with over 9 million observations per day. We find uniform pricing both within and across regions—i.e., product prices almost do not vary within stores of a chain. Uniform pricing implies that prices would not change with regional conditions or shocks, particularly so if chains operate in several regions. We confirm this hypothesis using employment data. While prices in stores of chains operating almost exclusively in one region do react to changes in regional employment, stores of chains that operate in many regions do not. Finally, ...
