Medicare Part D provides prescription drug coverage through Medicare approved plans offered by private insurance companies and HMOs. In this paper, we study the role of current prescription drug use and health risks, related expectations, and subjective factors in the demand for prescription...

In discrete choice labor supply analysis, it is often reasonably expected that utility will increase with income. Yet, analyses based on discrete choice models sometimes mention that, when no restriction is imposed a priori in the optimization program, the monotonicity condition is not fully...

This paper derives a revealed preference test for utility maximization under rationing and can detect, for which goods rationing is binding without specifying a functional form or imposing rationing constraints prior to estimation. For UK data from 1920–55, we find evidence of utility...

This paper develops and evaluates a rationing linear programming procedure that uses an “efficiency index” to allow for violations of revealed preference to be attributed to “almost” optimal choices. The procedure detects rationing using U.K. data. Various Monte Carlo simulations are...
