With these limitations in mind, it is interesting to note that market incomes at the 75111 and 90Lh percentiles have grown less strongly in the United States than in several other countries.7 The gains in this income range appear very large in Norway, Sweden and, particularly, the United Kingdom (Great Britain). Since the mid-90s, higher incomes also rose quickly in Finland and Poland. The data points are spaced several years apart and therefore do not capture the full income dynamics over the cycle. It appears, however, that any disruptions in the upwards trends for high-income groups during the downturns of the early 1980s and 1990s were short-lived.
