The RAND health insurance experiment randomly assigned subjects to one of four health insurance plans where the plans varied in the coinsurance rate. Listed below are mean outcomes for two measures of health care use for subjects in each of the four different health insurance plans. Using data from the free care and 95% coinsurance rate plans, calculate the elasticity of demand for total medical care and doctor visits. ("Estimating Price Elasticity of Demand") Plan Coinsurance Rate Outcome 0% (free care) 25% 50% 95% Total Medical care $1410 $1160 $1078 $1016 Annual doctor visits 4.55 3.33 3.03 2.73
