Nominal rigidities: how often do retailers really change prices?

Martin Eichenbaum of Northwestern University talks to Romesh Vaitilingam about his research on nominal rigidities and reference prices, which analyses a new weekly scanner data set from a major US retailer containing information on prices, quantities and marginal costs for every item in over 1,000 stores. The interview was recorded at the American Economic Association meetings in San Francisco in January 2009.
