10. Suppose in our model, lifespans increased due to a productivity in- crease. What would likely happen to hours worked and leisure over the lifetime of a represent ative consumer. (a) Let's consider one of two common ways of implementing this change. Suppose the increase raised both lifespans and the amount of years consumers are healthy enough to work by the same amount, how would that likely affect the measured numbered of hours work by prime aged adults within a given year? What would likely hap- pen to the retirement age? (b) Let's consider the other way to implement it. Suppose the change in lifetimes came about changes in technology that delayed death but did not extend the amount of years consumers are healthy enough to work. What would likely happen to hours worked within a year? What would happen to the retirement age? (c) In the US, the generalized stylized fact is that the actual age of retirement is not increasing. Nor are hours worked per week. Why are both of the above…

3. Consider the economic model of an individual's labor-leisure choice with the following components: C represents units of the consumption good L represents hours of leisure H represents hours of paid work p represents the unit price of the consumption good w represents the hourly wage rate Y represents nonlabor income T represents total time available U(C, L) represents the individual's utility function MUC denotes the marginal utility of consumption MUL denotes the marginal utility of leisure Unless otherwise instructed, assume that consumption and leisure are normal goods. Whenever graphi the model, put C on the vertical axis and L on the horizontal axis. What is the slope of the budget line? -(MUC/MUL) O-(MUL/MUC) O-W O -(w/p) O-(w+Y)/p

Mary is a corn farmer in Iowa. If she does not irrigate his field, she can produce 120 bushels of corn per acre. If she applies 4 inches of irrigation water, she can produce 140 bushels of corn per acre. The application of 8, 12, and 16 inches of irrigation water can result in 160, 180, and 200 bushels of corn per acre, respectively. Graph the relationship between the amount of water applied and corn yield for Mary (Assume a straight-line relationship). Find and interpret the slope and Y intercept

C-town brewery brews two beers: Expansion Draft and Burning River. Expansion draft sells for $14 per barrel while Burning River sells for $10 per barrel. Producing a barrel of Expansion Draft takes 5 pounds of corn and 8 pounds of hops. Producing a barrel of Burning River requires 2 pounds of corn, 8 pounds of rice, and 7 pounds of hops. The brewery has 770 pounds of corn, 490 pounds of rice, and 320 pounds of hops. Assuming a linear relationship, use the Excel Solver to determine the optimal mix of Expansion Draft and Burning River that maximizes C - town's revenue. Decision for expansion draft Decision for burning river Total sales Resources Used Corn Rice Hops

(Use this information to answer qustion 13 - 16) Suppose a household solves the following two-period consumption-savings problem max u(c1) + Bu(c2) {C1,C2} s.t. aw Y1 - C1 C2Y2 = (1+r) a with u(c) = √c where c₁ is consumption at time 1, c2 is consumption at time 2, ₁ is houshold income at time 1, y2 is houshold income at time 2 and w is the initial wealth. Suppose the incomes of the household are $50 in time 1 and $210 in time 2. The initial wealth is $100, the discount factor is 0.975 and interest rate is 5%. Solve for the household's choice of C1.
