This paper estimates and compares methods of constructing disaggregated house price indices from existing house price models using individual sales data for Sydney. Nine alternative house price models are selected to cover the most frequently used methods in the literature: the mean model,...

The average price of treating a colorectal cancer patient with chemotherapy increased from about $100 in 1993 to $36,000 in 2005, due largely to the approval and widespread use of five new drugs between 1996 and 2004. We examine whether the substantial increase in spending has been worth it....

The paper discusses the impact of distressed sales on recent estimates of house price changes in California. Using information from Notice of Default (NOD) filings in that state, the paper compares the usual FHFA HPI against an index computed after removing sales occurring after NOD filings. The...

It is often argued that price indexes do not fully capture the quality improvements of new goods in the market. Because of this shortcoming, price indexes are perceived to overestimate the actual price increases that occur. In this paper, I argue that the quality bias in price indexes is just as...

Statistical offices try to match item models when measuring inflation between two periods. For product areas with a high turnover of differentiated models, however, the use of hedonic indexes is more appropriate since they include the prices and quantities of unmatched new and old models. The...

We begin with a description of three house price panel data sets for the period 1982 to 1991. Next, we estimate a model that assumes the three sources are derived from an underlying unobserved price series, and we construct composite indexes that report house prices for 135 locations. These...

Trends in residential house values can be expressed by changes in House Price Indexes (HPIs). HPIs are based on observed prices and help guide real estate activities. Since the recent housing crash, distressed sales have increased in numbers and have led to concerns about their effects on market...

Changes in product characteristics on the extensive margin are an important and hitherto neglected dimension of quality change. Standard techniques for quality-adjusting price indices cannot handle such changes satisfactorily, which leads to an economically and statistically significant bias in...

The constant-quality assumption in repeat-sales house price indexes (HPIs) introduces a significant time-varying attribute bias. The direction, magnitude, and source of the bias varies throughout the market cycle and across metropolitan statistical areas (MSAs). We mitigate the bias using a...
