Testing for bubbles in housing markets: some evidence for Brazil

Abstract

Purpose Housing prices in Brazil have displayed an impressive growth in recent years, raising some concerns about the existence of a bubble in housing markets. In this paper, the authors implement an empirical methodology to identify whether or not there is a bubble in housing markets in Brazil. Design/methodology/approach Based on a theoretical model that establish that, in the absence of a bubble, a long-run equilibrium relationship should be observed between the market price of an asset and its dividends. The authors implement two methodologies. First, the authors assess whether there is a cointegration relationship between housing prices and housing rental prices. Second, the authors test whether the price-to-rent ratio is stationary. Findings The authors’ results show that there is evidence of a bubble in housing prices in Brazil. However, given the short span of the data, the authors perform a Monte Carlo simulation and show that the cointegration tests may be biased in small samples. Therefore, the authors should be caution when assessing the results. Research limitations/implications The results obtained from the cointegration analysis can be biased for small samples. Practical implications The information on the excessive increase of the prices of the properties in relation to their fundamental value can help in the decision-making on investment of the economic agents. Social implications These results corroborate the hypothesis that Brazil has an excessive appreciation in housing prices, and, as Silva and Besarria (2018) have suggested, this behavior explains, in part, the fact that the central bank has taken this issue into account when deciding about the stance of monetary policy of Brazil. Originality/value The originality is linked to the use of the Gregory-Hansen method of cointegration in the identification of bubbles and discussion of the limitations of the research through Monte Carlo simulation.

“…There is extensive literature that investigated housing price overvaluation (bubbles) in various regions and countries of the world. [see, for instance, Hou, 2010; Asal, 2019; Reiss, 2009; Micallef, 2018; Andreas Claussen, 2013; Wang et al , 2018; Ciarlone, 2015; Besarria et al , 2018; Taltavull and McGreal, 2009; Kok et al , 2018; Levin et al , 2011; Krakstad and Oust, 2015; Hott (2012)].…”

An examination of house price bubble in the real estate sector: the case of a small island economy – Fiji

“…Arestis et al (2017) reveal that Hong Kong house prices were overvalued by 31% relative to disposable income in 2013Q2 qualifying for the possibility of a bubble. Similarly, Besarria et al (2018) concluded evidence of a bubble in Brazil.…”

News shocks, government subsidies and housing prices in Brazil

“…Although the recent literature has reported the importance of including news shocks to explain the behavior of the real estate market, none of the studies applied to the Brazilian economy include this component. Recently, Besarria et al (2018a) explored the significance of overoptimism for house prices in Brazil using a theoretical model that establishes that, in the absence of a bubble, a long-run equilibrium relationship should be observed between the market price of an asset and its dividends. The authors implement two methodologies.…”
