Li & Yao: Your House Just Doubled in Value? Don't Uncork the Champagne Just Yet!

Overview

"Your House Just Doubled in Value? Don't Uncork the Champagne Just Yet!" is an article by Wenli Li, an economist in the Research Department of the Federal Reserve Bank of Philadelphia, and Rui Yao, then an assistant professor of finance at Baruch College's Zicklin School of Business, published in the Philadelphia Fed's Business Review, Q1 2006 (pp. 25–34).[1] It summarizes for a general audience the results of the authors' companion working paper, "The Life-Cycle Effects of House Price Changes" (Philadelphia Fed Working Paper 05-7, 2005), later published in the Journal of Money, Credit and Banking (2007).[1][2] The paper builds a dynamic life-cycle model in which households choose whether to rent or own, how large a house to buy, and how to invest and borrow over their lifetimes, then asks how a permanent house-price change affects each household's welfare — measured as the change in lifetime consumption needed to make a household indifferent to that price change.

The central finding is sharply distributional: a permanent 10 percent increase in house prices produces a lifetime-welfare loss of about 4.5 percent for renters and about 2 percent for young homeowners, while middle-aged homeowners are roughly unaffected (break-even around age 50) and only homeowners past about age 65 gain more than 2 percent in welfare.[1] Aggregated across the whole economy, the same 10 percent price rise produces a slight net welfare loss of 0.9 percent, because the losses to renters and young households are not fully offset by the gains to older owners.[1] The authors summarize the mechanism plainly: rising house prices "effectively transfer wealth from renters to homeowners and from young to old."[1] This directly complicates the popular framing that a hot housing market makes homeowners — and by extension "us" — straightforwardly richer, a framing discussed in Harrison's Ricardo's Law, which cites this research (Ch. 12.1) as part of its account of who wins and loses from the land-price cycle.
