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...

There is a potential bias in cross-sectional estimates of the effects of cigarette prices on cigarette consumption. States with the strongest antismoking sentiment will likely have the highest cigarette taxes, which result in the highest prices. Some of the lower consumption of cigarettes in...

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...

There are two broad classes of models used to address the econometric problems caused by skewness in data commonly encountered in health care applications: (1) transformation to deal with skewness (e.g., OLS on ln(y)); and (2) alternative weighting approaches based on exponential conditional...

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...
