A typical U.S. family devotes about a quarter of its annual income and half or more of its net worth to housing. Both the level and volatility of house prices thus have important implications for household behavior and welfare, as well as for the aggregate U.S. economy. Recent research has emphasized the importance of housing supply in determining house prices in different U.S. markets. This di...

The high prevalence of childhood asthma in low-income, inner-city populations is not fully understood but has been at least partly attributed to the disproportionate exposures associated with socioeconomic disadvantage. The contribution of indoor allergens to asthma is well documented, but links between socioeconomic disadvantage and indoor allergen levels are not clear. We investigated levels ...

Compared to the control group who stayed behind in public housing, the MTO voucher group exhibited a harmful...

Sound waste management and optimisation of resource recovery require reliable data on solid waste generation and composition. In the absence of standardised and commonly accepted waste characterisation methodologies, various approaches have been reported in literature. This limits both comparability and applicability of the results. In this study, a waste sampling and sorting methodology for ef...

For more than three decades, the evolving social, demographic and economic situation in developed nations has presented important challenges for housing designers, planners and investors, including those involved in the field of public intervention in social housing. Despite their undeniable merits on a theoretical level, efforts to respond to these challenges through new approaches in housing ...

Executive Summary ore than 100 cities and counties have adopted some form of a growth boundary—a limit on land development beyond a politically designated area—to curb sprawl, protect open space, or encourage the redevelopment of inner-city neighborhoods. Statewide mandates for growth boundaries exist in Oregon, Tennessee, and Washington. Urban-growth boundaries, however, have potentially negat...

Many housing and welfare researchers in the last few decades have dealt with the so-called trade-off debate concerning the trade-off between welfare and home ownership. Countries with a high home ownership rate have lower welfare arrangements. The debate is about the causality of this statistical relationship; is welfare low because the home ownership rate is high or is it the other way around....
