Discussion :
I choose to elaborate on scenario 1 which is the Affordable Care Act. This Act has been the target of many debates mainly because it is free which according to many would see an increase in health care visits which could affect tax payers pockets. To take a more indebt look at the statute I think the random field experiment model would be ideal as it tries to avoid biases (Langbien, 2012).
In utilizing the random field experiment a large sample size like an entire state would be effective with a combination of the mixed method way of collecting data. Participants should be randomly chosen but it is important that participants identify whether they currently have health insurance or not. This could no doubt influence the outcome of the research (Langbein, 2012).
Because the sample would be so large I think questionnaires would be the best way to collect data but it is imperative that the questions are based on the two above mentioned issues with the statute. Therefore, participants should give an idea about the amount of times they visit the doctor since the act came in effect and whether it was just for regular checkups or they were legitimately sick. They should also give an idea as to whether they visit the doctor more since health care becomes free versus when they had to pay. Depending on their answers and the ratio of one answer to another one can conclude whether free health care does influence health care visits and the effects it would have on tax payers pockets.
