Controlling for transactions bias in regional house price indices

Transactions bias arises when properties that trade are not a random sample of the total housing stock. Price indices are susceptible because they are typically based on transactions data. Existing approaches to this problem rely on Heckman-type correction methods, where a probit regression is used to capture the differences between properties that sell and those that do not sell in a given period. However, this approach can only be applied where there is reliable data on the whole housing stock. In many countries—the UK included—no such data exist and there is little prospect of correcting for transactions bias in any of the regularly updated mainstream house price indices. Thispaper suggests a possible alternative approach, using information at postcode sector level and Fractional Probit Regression to correct for transactions bias in hedonic price indices based on one and a half million house sales from 1996 to 2004, distributed across 1200 postcode sectors in the South East of England

Argentina's Housing Market in the 2000s

In the last three decades, the supply of housing in Argentina has not kept pace with demand. This study analyzes the main drivers of Argentinas housing market and relates them to the macroeconomic environment in order to advance a policy agenda for housing policy reform. The demand for housing was calculated and tenure choice was analyzed. Structural characteristics affecting Argentinas housing market include the high concentration of the urban population in a few large metropolitan areas, the association of urban poverty with the housing deficit, and overcrowding. The mortgage market lost its appeal following the 2001-02 crisis due to widespread breaches of contract legitimized through protective legislation (still in place), insufficient long-term financing, and high inflation. The housing deficit could be eliminated in five to eight years if well-coordinated policy initiatives to develop the mortgage market and provide low-income housing were adopted under a decentralized, demand-driven, subsidized program

Modelling UK house prices with structural breaks and conditional variance analysis

This paper differs from previous research by examining the existence of structural breaks in the UK regional house prices as well as in the prices of the different property types (flats, terraced, detached and semi-detached houses) in the UK as a whole, motivated by the uncertainty in the UK housing market and various financial events that may lead to structural changes within the housing market. Our paper enhances the conventional unit root tests by allowing for structural breaks, while including structural break tests strengthens our analysis. Our empirical results support the existence of structural breaks in the mean equation in seven out of thirteen regions of the UK as well as in three out of four property types, and in the variance equation in six regions and three property types. In addition, using a multivariate GARCH approach we examine both the behaviour of variances and covariances of the house price returns over time. Our results have significant implications for appropriate economic policy selection and investment management

Fertility Timing of Unmarried and Married Mothers: Evidence on Variation Across U.S. Cities from the Fragile Families and Child Wellbeing Study

In this paper, we examine the determinants of fertility timing of unmarried and married mothers using a rich new birth cohort study, the Fragile Families and Child Wellbeing Study, drawn from 20 medium and large U.S. cities. We find considerable variation in the time to next birth among comparable mothers who live in different cities. Some of this variation is explained by variation in labor markets, housing costs and availability, and welfare policies. City variation is particularly important for unmarried women who already have two or more children, whose fertility is more sensitive to these contextual variables than is the fertility of married women, or unmarried women with just one child
