At best, they made a choice based on misinformation–they thought they were working at a mine that met safety standards. Those of us who are tenured professors have indeed been free to chose; we can even say whatever we want without fear of losing our jobs. But to think everyone has such freedom is just delusional.

It did not so much disappointment me that he didn’t know (although the distinction is pretty easy–the debt is a stock and the deficit is a flow). It disappointed me that given that he knew he didn’t know, he still thought he had something worthwhile to say about the issue.

In 1989, average household income among 45-54 year olds was $39,934; average mortgage debt outstanding among those who had debt was $39,300, so the ratio was about one-to-one.

In 2007, average household income among 45-54 year olds was $83,100; average mortgage debt outstanding among those who had debt was $154,000, so the ratio was just under two-to-one.

In 1989, the share of households in the age group with a mortgage was 58.3 percent; in 2007 it was 65.5 percent.

The only good news: interest rates have dropped from about 10.5 percent to 5 percent. So in 1989, an average income household that wanted to amortize an average mortgage in 15 years would need to pay 14 percent of gross income to do so; in 1989 it would need to spend 19 percent. So putting this all together, the ratio of debt service to income for amortization by retirement has increased by (.19*.655/.14*.583)-1 = 52 percent. Not good, but not quite as bad as I thought, either.

My generation is different. Even under the most benign circumstances, we refinance in a manner that slows amortization. I refinanced in Madison twice to take advantage of lower interest rates–this was, of course, the right thing to do financially. But each time, the amortization schedule reset, and so it extended the period at which the mortgage would pay off. Now yes, one can take the money one doesn’t put into home equity and put it in other savings vehicles, but it is not clear that everyone does that. Forced saving is slowed.

But this is not the worst of how people have handled their mortgages. A substantial fraction of borrowers pulled equity out of their houses, putting themselves on a lower savings path even in the absence of falling house prices.

I am going to run some American Housing Survey data on this, but it is hard for me to imagine that 70 percent of my generation will have no mortgage debt when we are elders. My parents’ generation has used housing wealth to, among other things, finance long-term care. I hope I am missing something here, but the lack of housing wealth in the future could become yet another challenge as we seek to fund the needs of the elderly.

The recent trend of immigrants arriving in mid-size metropolitan areas has received growing attention in the literature. This study examines the success of immigrants in the housing markets of a sample 60 metropolitan areas using Census microdata in both 2000 and 2005. The results suggest that immigrants are less successful in achieving homeownership and more likely to live in overcrowded conditions than native-born whites of non-Hispanic origin. The immigrant effect on homeownership differs by geography and by immigrant group. Finally, we find evidence that immigrant networks increase the likelihood of becoming a homeowner.

Has Blackberry become the new Kleenex? If so, they need to be careful. Aspirin was once a brand, but it became such a strong part of the lexicon, that Bayer lost the ability to retain it.

But our particular brand of single-use zoning has doubtlessly had an impact on settlement patterns. At minimum, we have insufficient land zoned for apartments. We know this because land zoned for multifamily use often sells for more (controlling for location) than land zoned for single-family use. This is not the market–this is local government holding back the supply of a certain type of land use. Moreover, minimum lot size, set back and street width requirements mean we use more land than necessary to build even single-family housing.
