I’m often asked why my research is economics and not sociology. Justin Wolfers and Betsey Stevenson give one answer as part of a longer Q&A on their research:
Your other areas of research focus include marriage, divorce, and family. Why would these areas interest economists? Or business leaders?
Dr. Stevenson: Economics is about how people make decisions optimally, given that they’re facing constraints. That framework can be applied anywhere, not just to things that are about dollars and cents and the economy. Families and labor markets are intimately connected, and to understand one, it’s helpful to understand the other. That’s because decisions about labor force participation and about what kinds of jobs to take and what kind of hours to keep are made within the context of family lives. What happens in families affects the way people make those kinds of decisions. And what happens in labor markets affects the decisions people make about families. Economists are also interested in families because we have come to realize that there are many parallels between family and labor markets.
Dr. Wolfers: The first place that people notice the similarities between family and economics is in what some have called the marriage market, which looks a whole lot like the labor market. People search for partners the same way they search for jobs. When you find a spouse or a job that looks like a good fit, you take it. And you must make a decision about how much time to spend searching for the perfect spouse or the perfect job before accepting a job or a spouse.
