Some economists have argued that assortative mating between men and women has increased over the last several decades. Sociologists have argued that educational homogamy has increased. The two are conceptually distinct but often confused. We clarify the relation between the two and, using both the Current Population Surveys and the decennial Censuses/American Community Survey, show that neither conclusion is correct. Both are sensitive to how educational categories are chosen. The former is based on the use of inappropriate statistical techniques.

This paper is the first to present empirical evidence consistent with models of signaling through unemployment and to uncover a new stylized fact using the 1988–2006 Displaced Worker Supplement (DWS) of the Current Population Survey (CPS), namely that, among white-collar workers, post-displacement earnings fall less rapidly with unemployment spells for layoffs than for plant closings. Because high-productivity workers are more likely to be recalled than low-productivity ones, they may choose to signal their productivity though unemployment, in which case the duration of unemployment may be positively related to post-displacement wages. Identification is done using workers whose plant closed as they cannot be recalled, and no incentives to signal arise.

This paper uses a representative sample of U.S. workers to examine how self-employment may reduce work-life conflict. We find that self-employment prevents work from interfering with life (WIL), especially among women, but it heightens the tendency for life to interfere with work (LIW). We show that self-employment is connected to WIL and LIW by different causal mechanisms. The self-employed experience less WIL because they have more autonomy and control over the duration and timing of work. Working at home is the most important reason the self-employed experience more LIW than wage and salary workers.
