Providing free health insurance to low-income individuals may increase health careaccess, and thus improve objective measures of health (e.g., blood pressure, heartrate, blood sugar levels) among low-income individuals.a) Why can't we test this hypothesis by simply comparing the objective healthmeasures of low-income individuals who have free health insurance to those who donot have free health insurance? Explain.b) What would be a better method to credibly test this hypothesis using quasi-experimental methods? Explain.
