Many analyses of healthcare costs involve use of data with varying periods of observation and right censoring of cases before death or at the end of the episode of illness. The prominence of observations with no expenditure for some short periods of observation and the extreme skewness typical...

Health economists often use log models (based on OLS or generalized linear models) to deal with skewed outcomes such as those found in health expenditures and inpatient length of stay. Some recent studies have employed Cox proportional hazard regression as a less parametric alternative to OLS...

Limited evidence exists on whether expanding home care saves money overall or how much institutional long‐term care can be reduced. This paper estimates the causal effect of Medicaid‐financed home care services on the costs and utilization of institutional long‐term care using Medicaid...

SUMMARY When fitting an econometric model, it is well known that we pick up part of the idiosyncratic characteristics of the data along with the systematic relationship between dependent and explanatory variables. This phenomenon is known as overfitting and generally occurs when a model is...

SUMMARY Market‐based solutions are often proposed to improve health care quality; yet evidence on the role of competition in quality in non‐hospital settings is sparse. We examine the relationship between competition and quality in home health care. This market is different from other...

General health state classification systems, such as the EuroQol instrument, have been developed to improve the systematic measurement and comparability of health state preferences. In this paper we generate valuations for EuroQol health states using responses to this instrument's visual...
