All monetary' amounts are expressed in 2010 constant dollars. Model results were found to be within the ranges reported in the literature and in conformance with the theoretical expectation that small firms would have a more elastic demand for health insurance than would larger firms. Sensitivity analysis, where different combinations of potential covariates were used to estimate firm utility, was undertaken and the base case model specification was determined to be the most appropriate. A sensitivity analysis was undertaken where the probability of offering a new insurance option (one of the options available through the new insurance exchanges) estimated from the model was adjusted downward to match other estimates in the literature.
