In the following table, indicate whether the researcher in the scenario is collecting experimental data or observational data. Experimental Scenario Data A pediatrician randomly assigns babies to two different groups, giving one group a new type of infant formula and the other group conventional formula, in order to study the effects of the new formula. O An oncologist randomly assigns rats into two groups, giving one group a new drug intended to fight cancer and giving the other group a placebo, in order to study the effects of the new drug. A sociologist conducts interviews with former protestors and activists in order to study the struggles of the civil rights movement. The issue of reverse causality is more likely to be present in data sets than in O data sets. Observational Data O O

Exercise 2. Describe the difference between allocative efficiency and productive efficiency in theproduction of health. Assume researchers prove beyond a shadow of doubt that allocative efficiencyand productive efficiency are both causal mechanisms for the production of health. Should theUnited States spend more money educating its citizens if the goal is to become the healthiest nationin the world? [

Suppose, as an economist, you are asked to analyze an issue unlike anything you have ever done before. Also, suppose you do not have a specific model for analyzing that issue. What should you do? Hint: What would a carpenter do in a similar situation?
Is the economic model of decision-making intended as a literal description of how individuals, firms, and the governments actually make decisions?
1. What is the advantage of an experimental study? a. Experimental studies are less expensive to conduct than observational studies b. The researcher can eliminate bias by removing the influence of confounding factors c. The results of an experimental study are usually more generalizable than the results of an observational study d. Experimental studies identify correlation instead of causation 2. Researchers conduct a study measuring how house prices jump across school zone boundaries. They find that houses on the lower-ranking side of a school zone boundary have distinctly lower prices than houses on the higher-ranking side of a school zone boundary. This is an example of: a. An experimental study b. An instrumental variables study c. A regression discontinuity study d. A difference-in-differences study

5. 7) Fifteen years ago, the town of Easton decided to increase its annual spending on education so that its high school graduates would be able to earn higher wages. Now Easton has asked you to evaluate the effectiveness of the spending increase. Their data show that before the spending increase, the average salary of recent high school graduated was $25,000 and that now the average salary has risen to $28,500. Fortunately for your analysis a neighboring community did not change its annual spending on education. In the other town 15 years ago high school graduates earned an average of $22,500, and now the average is $23,750. a) Use a differences-in-differences estimator to determine whether Easton’s spending increase potentially caused the wages of high school graduates to rise. b) What underlying assumption do you have to make in order for your estimate to be valid? What might cause that underlying assumption to not be valid?
# 10 An example of efficiency in economics is Select one: Satisfying wants with as many resources as possible Simplifying reality in economic models as much as possible Minimising outputs given inputs Maximising outputs given inputs
When using the social ecological model, which of the following would be considered part of the "exosystem" of influence on an individual's physical activity? O Personal factors O public policy O Institutional factors O Exosystem does not exist in the social ecological model If you have a client who wants to work out on his own, which of the following method of prescribing exercise intensity you should recommend to be more accurate? O Rating of perceived exertion (RPE) O Talk test O % Age predicted HRmax O % Heart rate reserve (measured)
Show how a consumer would choose between medical care and health(y) behavior activities using the graphical representation of the consumer choice model (assume that “amounts” of healthy behavior have “costs” or prices). How might health education affect this choice? What if medical care becomes more productive (more health benefit per “unit” of medical care consumed)? What if medical care becomes cheaper? Explain in terms of the model (i.e. what does it change in the model).
12.Which of the following is true of an economic theory? a. It uses complex mathematical equations to explain the problem of scarcity of resources b.It seeks to prove political ideals and establish a moral code of conduct c. It seeks to strengthen the role of the government in an economy d. It is a deliberate simplification of factual relationships
In an article on how exercise improves health, the New York Times reported on an observational study that found that each hour spent running added two hours to a person's life expectancy [Brody. 20061 A week later, a letter to the editor questioned whether the results really proved anything about the impact of exercise on health, and suggested that the study could just as well be showing that "those with a strong heart and good health are otherwise more likely to enjoy running and do it more regularly." How does this challenge to the exercise study relate to the problems faced by economists trying to &slims the causal effects of economic policy? How could you design an experimental study to estimate the impact of running on life expectancy?
