Episodes of Exuberance in Housing Markets: In Search of the Smoking Gun

In this paper, we examine changes in the time series properties of standard housing market indicators (real house prices, price-to-income ratios, and price-to-rent ratios) for a large set of countries to detect episodes of explosive dynamics. Dating exuberance in housing markets provides a timeline as well as empirical content to the narrative connecting housing exuberance to the global 2008?09 recession. For our investigation, we employ two recursive univariate unit root tests developed by Phillips et al. (2011) and Phillips et al. (2015). We also propose a novel extension of the Phillips et ...

exuber: Recursive Right-Tailed Unit Root Testing with R

This paper introduces the R package exuber for testing and date-stamping periods of mildly explosive dynamics (exuberance) in time series. The package computes test statistics for the supremum ADF test (SADF) of Phillips, Wu and Yu (2011), the generalized SADF (GSADF) of Phillips, Shi and Yu (2015a,b), and the panel GSADF proposed by Pavlidis, Yusupova, Paya, Peel, Martínez-García, Mack and Grossman (2016); generates finite-sample critical values based on Monte Carlo and bootstrap methods; and implements the corresponding date-stamping procedures. The recursive least-squares algorithm that ...

Taking the Global Housing Market’s Temperature: Is It Running a Fever (Again)?

The current trajectory prompts the question: Do markets face the prospect of a housing bubble once again? Alternatively, are price increases in step with housing market fundamentals?

Detecting Periods of Exuberance: A Look at the Role of Aggregation with an Application to House Prices

The recently developed SADF and GSADF unit root tests of Phillips et al. (2011) and Phillips et al. (2015) have become popular in the literature for detecting exuberance in asset prices. In this paper, we examine through simulation experiments the effect of cross-sectional aggregation on the power properties of these tests. The simulation design considered is based on actual housing data for both U.S. metropolitan and international housing markets and thus allows us to draw conclusions for different levels of aggregation. Our findings suggest that aggregation lowers the power of both the SADF ...
