This paper develops a new simulation estimation algorithm that is particularly useful for estimating dynamic panel data models with unobserved endogenous state variables. The new approach can deal with the commonly encountered and widely discussed ``initial conditions problem,'' as well as the...

Two key issues in the literature on female labor supply are (i) whether persistence in employment status is due to unobserved heterogeneity or state dependence, and (ii) whether fertility is exogenous to labor supply. Until recently, the consensus was that unobserved heterogeneity is very...

Two key issues in the literature on female labor supply are: (1) if persistence in employment status is due to unobserved heterogeneity or state dependence, and (2) if fertility is exogenous to labor supply. Until recently, the consensus was that unobserved heterogeneity is very important, and...

This article develops a simulation estimation algorithm that is particularly useful for estimating dynamic panel data models with unobserved endogenous state variables. Repeated sampling experiments on dynamic probit models with serially correlated errors indicate the estimator has good small...

A review of the basic theory of optimal open-source software contributions points to three key factors affecting the decision to contribute to the open-source development process: nonpecuniary benefits, future expected monetary returns, and open-source licence type. This paper argues that...

This paper argues that drugs are expensive not because of a lack of competition among research-based pharmaceutical companies, but because of a lack of competition in the drug approval process. Lack of competition in the drug approval process has led to exceedingly high drug development costs....
