Q: Based on your index of American home prices going back to 10S0, where are we now in terms oj moving lower to earlier price levels? Are we back to 2002 home-price levels?

A: It's hard to be precise about these things. Looking at the plot, it looks like we're almost back to | the| average level for the century from 1890 to 1990 |see Figure i|. People would have imagined that there was an uptrend in that period. But in fact, there wasn't. There was virtually no change in real inflal ion corrected home prices between 1890 and 1990. And so I think it's meaningful to talk about the level - but only roughly, because we don't measure these things accurately.

But the thing is, that over the century, from 1890 to 1990, land was, of course, getting more scarce. So you might think that home prices would rise in real terms. But offsetting that were improvements in the technology of building homes. And actually, the percentage of home value that is accounted for by land is small - maybe 20 percent. So it just kind of canceled out and there was no change.

It looks like we are almost back ito the average real price for the century|. We are still high, but it's something like 20 percent, 10 percent. I have been quoted a lot for saying that home prices might fall another 10 ipercent] to 25 percent. That was just a guess of what might happen. But it's based on this chart (Figure 1). Actually, 1 said that [back| in February 2011 - I was referring to a decline from the first quarter of 2010. That idegree of potential decline in home prices is] the kind of fall that would get us back to where we were for 100 years.

Q: So that didn't include the decline that has occurred this year?

A: Our national index went down 4 percent in the firs! quarter. I don't know what home prices are going to do. As I said then, in real terms, they might well decline further. I just don't have any way of knowing. And if you look at this chart, it wouldn't be outlandish to see iprices) fall from fourth quarter of i2010] by 10 ipercent] to 25 percent in real terms. I just don't know what [they] will do.

Q: Could real prices go lower than the trend linethat s what you see in [Figure 1] for the period of the 1020s and 1930s? …
