Robert Shiller is a leading expert on US Home prices and is the co-creator of the widely cited Case-Shiller Home Price Indices. Here is the most interesting quote from the interview for mine;
"There's a lot of misconceptions about home prices, people think that there is a strong historical uptrend to them. In fact by my data there is not. In fact home prices in the United Sates if you correct for inflation, in 1990 were about the same as they were in 1890."
Well worth a watch.
