Trends in men's earnings volatility

"Using Panel Study of Income Dynamics data for 1969 through 2004, we examine movements in men's earnings volatility. Like many previous studies, we find that earnings volatility is substantially countercyclical. As for secular trends, we find that men's earnings volatility increased during the 1970s, but did not show a clear trend afterwards until a new upward trend appeared in the last few years. These patterns are broadly consistent with the findings of recent studies based on other data sets"--National Bureau of Economic Research web site.
