It has been recently emphasized that, if individuals have heterogeneous dynamics, estimates of shock persistence based on aggregate data are significatively higher than those derived from its disaggregate counterpart. However, a careful examination of the implications of this statement on the various tools routinely employed to measure persistence is missing in the literature. This paper formal...

Incorporating spatial econometric tools in Hedonic Pricing (HP) models for environmental valuation has become the standard approach in the literature. The effect of house prices on other house prices is taken into account and usually measured by distance or contiguity in spatial weight matrices. Disaggregate house sale datasets are composed from observations each at a specific location and time...

The passage of welfare reform renewed a long-standing debate over whether improved public transit would significantly lessen the length of time that people remain on welfare. Language of the act reflects an assumption that it would. On the other hand, the automobile provides such a high level of service and is so widely available even to the poor that it is difficult to comprehend how improved ...

Longitudinal models are becoming increasingly prevalent in the behavioral sciences, with key advantages including increased power, more comprehensive measurement, and establishment of temporal precedence. One particularly salient strength offered by longitudinal data is the ability to disaggregate between-person and within-person effects in the regression of an outcome on a time-varying covaria...

these potential relationships. The results have been mixed, with some finding net substitution and some finding complementarity [refer to Mokhtarian and Salomon (4) for a review]. Most of those studies, however, have taken a disaggregate approach and have been conducted on small samples, often focusing on just a single application such as telecommuting, teleconferencing, or Internet shopping. A...

According to the predominant theories, soluble amyloid-beta (Aβ) aggregates are the principal neurotoxic agents in Alzheimer's disease pathology, making them a popular target for the development of therapeutics and diagnostic markers. One of the most commonly used methods for determining the concentration of Aβ is ELISA. However, ELISA was developed for monomeric proteins and may be ill-suited ...

We conduct an empirical comparison of nine representative statistical pavement performance models, which have been estimated using serviceability data from the AASHO Road Test. The purpose of the study is to understand the effect of different statistical assumptions and estimation techniques on the models’ predictive capabilities. The study consists of using the models to predict the serviceabi...
