This paper examines the changes in the size distribution of firms in the abortion services market between 1978 and 1992 in the US. The results indicate that for the entire 15-year period, the market shares of large abortion providers were increasing in both restrictive and nonrestrictive states. Also clinics and physician offices appear to be gaining market share relative to hospitals. These increasing market shares could be due to many factors, such as changes in the technology of providing abortions on an outpatient basis and changes in the relative prices of abortions in hospitals and abortions in non-hospital settings. Furthermore, this paper includes an analysis of the impact of state-level Medicaid funding regulations on the number, size, and type of abortion provider. These results have important implications for women's access to abortion services and for infant and maternal health.

This paper develops a new class of Rosenbrock-type integrators based on a
Krylov space solution of the linear systems. The new family, called
Rosenbrock-Krylov (Rosenbrock-K), is well suited for solving large scale
systems of ODEs or semi-discrete PDEs. The time discretization and the Krylov
We calculate the optimal rotational configuration of N-fold rings on a hexagonal lattice and establish two related mechanisms for the promotion of maximum excitation energy transfer (EET). (i) For certain fold numbers, there exist optimal basis cells with rotational symmetry, extendable to the entir...
