6. Suppose we have a quantity x that varies with time t, which we write x(t) to indicate that it can be different at different times. Define dx(t)/dt to stand for that quantity's rate of change with time. (Don't blame me: blame Newton and Liebnitz.) If x(t) follows the equation: dx(t)/dt = -(0.06)x + 0.36, at what level of x will it be constanti.e., not changing over time? Call that equilibrium value x*. If x(t) > x*, is x growing or shrinking over time? If x(t) < x*, is x growing or shrinking over time? Is x* a stable equilibrium or an unstable equilibrium?

3. Suppose that the appliance store buys a refrigerator from the manufacturer on December 15, 2010 for $600, and that you then buy that refrigerator on February 15, 2011 for $1000: a. What is the contribution to GDP in 2010?

b. How is the refrigerator accounted for in the NIPA in 2010?

c. What is the contribution to GDP in 2011?

d. How is the refrigerator accounted for in the NIPA in 2011?

4. Is real GDP per worker a good measure of material welfare? Of human well being? Why do you think it is or is not?

5. Suppose a quantitylike real GDP per workergrows at a steady proportional rate of 2.4% per year. How long will it take to double? Quadruple? Grow 1024-fold?

To evaluate a government training program that provides low-income, low-skilled, disadvantaged persons job-specific training, members of the target population who live in the southern part of council are assigned to a treatment group that is eligible to receive services under the program, while members of the target population who live in the areas in the northern half of the state are assigned to a comparison group that is not. Information is collected on the earnings, welfare receipts, and so forth of both groups for one year prior to the beginning of training, during the training period, and for two years thereafter. Decide which type of research design it is advised to use.
