The maximum likelihood estimator for the regression coefficients, β, in a panel binary response model with fixed effects can be severely biased if N is large and T is small, a consequence of the incidental parameters problem. This has led to the development of conditional maximum likelihood...

We examine the effect of an income-based mandate on the demand for private hospital insurance and its dynamics in Australia. The mandate, known as the Medicare Levy Surcharge (MLS), is a levy on taxable income that applies to high income individuals who choose not to buy private hospital...

We examine variation in US hospital quality across ownership, chain membership, and market concentration. We use a new measure of quality derived from the penalties imposed on hospitals under the flagship Hospital Readmissions Reduction Program. We document a robust and sizable negative...
