Cecchetti et al. (2002) estimate the half-life to price index convergence among U.S. cities to be approximately nine years. Although they correct for the small-sample bias in their panel estimate of the half-life, they do not adjust for biases that may potentially arise due to heterogeneity in the dynamic behavior of prices across cities, and time aggregation of price indices. This paper finds ...

ABX.HE indexed credit default swaps on baskets of mortgage-backed securities are now the main benchmark used by financial institutions to mark their subprime mortgage portfolios to market. However, we find that current prices for the ABX.HE indices are inconsistent with any reasonable assumption for mortgage default rates, and that ABX.HE price changes are only very weakly correlated with obser...

INTRODUCTION The role of craving in nicotine dependence remains controversial and may be a function of measurement challenges. The current study used behavioral economic approach to test the hypotheses that subjective craving from acute withdrawal and exposure to tobacco cues dynamically increases the relative value of cigarettes. METHODS Using a 2 (1-hr/12-hr deprivation) × 2 (neutral/tobacc...

We create a hedonic price model for house prices for six geographical submarkets in the Netherlands. Our model is based on a recent data mining technique called boosting. Boosting is an ensemble technique that combines multiple models, in our case decision trees, into a combined prediction. Boosting enables capturing of complex nonlinear relationships and interaction effects between input varia...

In several studies, hedonic methods have been used successfully for the ex post assessment of the accuracy of inflation measurement. Most of these studies relate to high-tech products, with respect to which traditional methods of compiling price indices often fail. We apply hedonic methods to rental housing services, which display less quality progress. However, as German households spend about...

We apply two non-parametric methods to test further the hypothesis that log-periodicity characterizes the detrended price trajectory of large financial indices prior to financial crashes or strong corrections. The analysis using the so-called (H, q)-derivative is applied to seven time series ending with the October 1987 crash, the October 1997 correction and the April 2000 crash of the Dow Jone...

Statistical offices use the matched models method to compile consumer price indices (CPIs) to measure inflation. Price collectors record the prices of a sample of models or varieties of selected products existing in period t, and then continue to record the prices of these same matched models in subsequent periods t+n. The matched models method is designed to control for quality changes by ensu...
