Have housing costs turned the urban wage premium into a penalty?
Core argument: Non-college workers moving from low- to high-density U.S. areas earned a housing-inclusive wage premium above 10% in 1970, but faced an urban penalty of over 10% by 2015.
Over the past 50 years, non-college workers have experienced a significant decline in the urban wage premium, turning into a housing-inclusive urban wage penalty of nearly 20% between 2000 and 2015. In 1970, these workers could expect a housing-inclusive wage premium of over 10% when moving from low to high-density areas, but by 2015, this shift resulted in an urban penalty of over 10%. This trend is driven by escalating housing costs and declining relative wages, making high-density areas less attractive for non-college workers. Conversely, college-educated workers continue to enjoy a substantial urban wage premium, with hourly wages increasing by approximately 50% over the same period. The disparity highlights the economic challenges faced by non-college workers in urban settings, as housing costs negate potential wage benefits.

















Ed Comment:“I took a first read of your paper over the weekend (a topic that interests me greatly) and love where you are heading. Congrats. Two aspects of the data have always given me pause—differential real estate appreciation by relevant neighborhood/demographic (i.e., high-skilled vs low-skilled) and migration of non-native-borns. Obviously, an influx of high-skilled workers raises real estate prices on average, especially real estate desirable to high-skilled workers. Increased demand for real estate from an influx of high-skilled workers surely spills over into low-skilled neighborhoods at the margin. Although given the share of high-skilled workers (say 5%) to low-skilled workers (66%), one might suspect the spillover is smaller than the sky-is-falling media admits. We care more about the dynamics of low-skilled housing price appreciation relative to low-skilled wages, and why an increase in low-skilled real estate prices lowers low-skilled after-rent wages (rather than proportionately raising low-skilled wages), especially when real estate restricts the supply of low-skilled labor. We know from Moretti that low-skilled wages are significantly higher in faster growing cities (i.e., compensated for some of the higher costs). You would also think that as low-skilled wages and real estate prices rise, low-skilled workers would find it increasing economical to commute longer distances to capture higher wages and avoid higher priced real estate. Given these dynamics, I can’t help but wonder if an influx of non-native-born low-skilled workers willing to accept lower after-rent wages has squeezed low-skilled after-rent wages rather than an influx of high-skilled workers. It’s not hard to imagine low-skilled migration patterns being further exacerbated by ethnic non-native born immigrants finding ethic low-skilled neighborhoods (and schools) more desirable than native-borns, and vice versa.”
Ed Comment: “Housing expenditures as a share of income segregated by income level solves my concern about segregating the housing data.I’m still left looking for reasons/evidence why low-skilled urban after-rent wages have fallen, especially if the supply of real estate isn’t restricted by something other than replacement cost (i.e. unrestricted other than the cost of commuting). I suppose one reason could be changing preferences where people might spend a greater share of their income on housing (and healthcare) as other things grow cheaper (or they price the growing benefits of urbanization into real estate). But that doesn’t explain why native-borns are/seem to be affected differently (i.e. migrating away instead of to urban areas).One answer is native-borns owned houses in urban areas and are now selling them to consume their imbedded equity (probably as part of a retirement strategy) rather than suffering lower after-rent wages. But I still have a sneaking suspicion that without the non-native born low-skilled migration, we are missing an important part of the picture. What other than a growing demand for urban jobs and low-skilled urban real estate (in ethnic neighborhoods) would drive down low-skilled urban after-rent wages significantly?Whenever I try to hire domestic employees, they insist on working off the books unless I pay them their taxes. I suppose if they can work next door for more, I would have to pay the difference. But if I have to pay their taxes, why wouldn’t I have to equilibrate all the additional costs necessary for them to urbanize? It’s hard to imagine urban labor markets as monopsonies. Again, it leads you to believe the demand for urbanization must growing despite the increased cost—a contradictory conclusion if native-borns are moving away.”
Stan Comment:“Thanks for the note, Ed. We’re planning on looking at the migration issues a little more closely. Keep in mind though that there are still quite a few places where housing costs don’t exceed construction costs by much. I’m less concerned about residential segregation by income/skill because we use actual spending numbers. A separate issue I’m worried about is cost of living heterogeneity (besides housing) for college workers. Not quite sure yet how to think about that. See you soon Stan”
