We introduce a computationally tractable dynamic equilibrium model of the automobile market where new and used cars of multiple types (e.g. makes/models) are traded by heterogeneous consumers. Prices and quantities are determined endogenously to equate supply and demand for all car types and...

We present a fast and accurate computational method for solving and estimating a class of dynamic programming models with discrete and continuous choice variables. The solution method we develop for structural estimation extends the en- dogenous grid-point method (EGM) to discrete-continuous...

This paper compares the performance of the Howard (1960) policy iteration algorithm for infinite-horizon continuous-state Markovian decision processes (MDP's) using alternative random, quasi-random, and deterministic discretizations of the state space, or grids. Each grid corresponds to an...

This paper uses a life cycle model to predict the induced entry effects of a reduction in the effective tax rate applied to Social Security Disability Insurance recipients from 100% under the status quo to a 50% tax rate (i.e. $1 dollar benefit reduction for every $2 earned over a disregard...
