Between 1965 and 1985, the Western world and the United States in
particular experienced a staggering amount of social and economic
change. In Birth Quake, Diane J. Macunovich argues that the common
thread underlying all these changes was the post-World War II baby
boom--in particular, the passage of the baby boomers into young
adulthood.
Macunovich focuses on the pervasive effects of changes in relative
cohort size, the ratio of young to middle-aged adults, as masses of
young people tried to achieve the standard of living to which they had
become accustomed in their parents' homes despite dramatic reductions in
their earning potential relative to that of their parents. Macunovich
presents the results of detailed empirical analyses that illustrate how
varied and important cohort effects can be on a wide range of economic
indicators, social factors, and even on more tumultuous events including
the stock market crash of 1929, the oil shock of 1973, and the Asian flu
of the 1990s. Birth Quake demonstrates that no discussion of business
or economic trends can afford to ignore the effects of population.
