This paper investigates price-setting for truly homogenous products sold in markets without
any formal trade barriers. We use data from IKEA, a furniture company selling identical
products in an identical shopping environment in different EU countries. We get four
remarkable outcomes: 1) The law of one price does not hold. 2) Country-specific effects of
non-tradable cost components are important. 3) Pricing to the market surely occurs but price
discrimination is limited by incomplete information. 4) The unexplained part of betweencountry
price variation for identical products is about 75% which leaves most of the intercountry
price variation unexplained
