Retail prices in Canada fluctuate with inflation, market integration at mid-century peak.
A new study looked at prices of goods in Canada from 1910 to 1950 and found that how often prices change depends on inflation rates, with more changes in the 1920s and 1970s. Surprisingly, retail prices were more similar across cities in the 1950s than in the 1990s. The study also found a connection between how often prices change and how different prices are between cities.
