with the strongest growth at the top; again, as in the other cities, the household income distribution, which includes the unemployed, is more unequal than the earnings distribution. Although some industries associated with globalization have increased their size, as in Tokyo upper-level occupations have not expanded. Thus, Preteceille (1997) does not find in Paris the professionalization of the workforce that Hamnett discovered in London. Preteceille finds that the most important reason for income growth at the top results from the return on assets. Nevertheless, the range of salary inequality has also increased; the lowest level has received a decreasing share but stable wages, while the top has made disproportionate gains. Unexpectedly within the context of both globalization and regulation theory, the size of the public sector has increased. There has been a limited but noticeable enlargement of intermediate groups and increased stability of their share. Opposite to the other four regions, salary inequality has increased more quickly outside the core area of the Ile-de-France than within it.
