Using quarterly data for 42 products over the period from 1990 to 2015, we find that there has been a large and growing dispersion of purchasing power across U.S. cities since 1990 and the dispersion varies widely across products. We also find that total factor productivity shock precedes or predicts the rise in regional inequality of purchasing power. We view that the growing regional inequality found in the purchasing power among U.S. cities might have proceeded after nationwide productivity shocks mainly by the cities with higher share of skilled workers through the products with more flexible price adjustments.
