Estimating Pricing Rigidities in Bilateral Transactions Markets

Many price indices are constructed using bilateral transaction prices. This paper shows how the time series behavior of cross-sectional price moments can reveal useful information about pricing behavior in bilateral transactions markets. Inference is formalized in a microlevel price determination model that allows for rigid pricing at the level of individual buyer/seller transactions as well as asymmetries in bargaining power. The model is used to estimate pricing rigidities in Norwegian salmon export transactions. Results suggest a high rate of price revisions and an informative salmon price index. The moments suggest price revisions are conducted at fixed time intervals consistent with optimal price revisions under costly information and that price revisions are more likely when transaction prices are below the reference price in the market.
