Why Have Unemployment Rates in Canada and the U.S. Diverged?

Throughout the post-war period, U.S. and Canadian unemployent rates moved in tandem, but this historical link apparently ended in 1982. During the past three years, Canadian unemployment rates have been some three percentage points higher than their U.S. analogues, and this gap shows no sign of diminishing. This paper is an empirical evaluation of a variety of explanations for this new unemployment gap. We first show that the demographic and industrial composition of the two countries is remarkably similar, so that no simple mechanical hypothesis explain the basic puzzle. It is also evident that the increase in Canadian unemployment relative to U.S. unemployment can not be fully attributed to output movements. We find that the gap between actual and predicted Canadian output, based on U.S. output, has fallen dramatically since 1982 while the unemployment gap has widened. We also find that unemployment in Canada was 2 to 3 percentage points higher in 1983 and 1984 than predicted by Canadian output. We have investigated a variety of hypotheses to explain the slow growth of employment in Canada after 1982. These hypotheses attribute the slow growth of employment to rigidities in the l
