The California Simulation of Insurance Markets (CalSIM) model was developed by the UC Berkeley Center for Labor Research and Education and the UCLA Center for Health Policy Research to estimate the impacts of the Affordable Care Act on employer decisions to offer insurance coverage and individual decisions to obtain coverage in California. The model was funded by The California Endowment. The report's authors are Laurel Lucia, Ken Jacobs, Miranda Dietz, Dave Graham-Squire, Nadereh Pourat, and Dylan H. Roby. The report acknowledges the involvement of Daphna Gans, Christina Kinane, Gerald Kominski, Jack Needleman, Greg Watson, and Xiao Chen in developing CalSIM, as well as support and helpful input from Claire Brindis and the UCSF Philip R. Lee Institute for Health Policy Studies. The authors also thank Len Finocchio, Neelam Gupta, Peter Lee, Richard Thomason, and Lucien Wulsin for their helpful comments, and Jenifer MacGillvary for her help in preparing the report.
