Essentials Final x + s/Microeconomic%20Essentials%20Final%200SA.pdf W 8 / 18 90% + QUESTION 12 Consider the following scenario: Q (4 Marks) Steven owns his own auto repair shop. He uses his own premises as a workshop. If he had rented his premises to someone else, he would have received R18 000 in rent. He initially invested R50 000 in his business to buy tools and machines. If he had invested the money, he could have earned 10% per year on the money, which is R5 000 per year. If he did not work for himself, he could have earned a salary of R60 000. His expenditure for the year consisted of the following: Oil, petrol, sparkplugs, fan belts and other materials: R70 000 Salary for two junior mechanics: R35 000 Admin costs: R15 000 Assume that the total revenue of the auto shop is R230 000. Calculate Steve's economic profit. a) R203 000 b) R110 000 c) R27 000 d) R32 000 DOLL 11 ENG 2024/0

13) With the money stock growing and assuming that the endowment of the young is time, the following consequence(s) proceed: A) The youngs' desire to work increases. B) The youngs' leisure consumption increases C) The youngs' demand for money increases D) All of the above.

1) Sharon spends her time (20h) between leisure (L) and work and he consume Y product from his working income (Py=1). Assume that she gets W$ per hour of working and has the following utility function: U (L, Y)=LY+2L a. b. C. Calculate the demand function for L and show it on a graph (L vs W). Calculate the labor supply (H) and show it on a graph (H vs W). What will happen to L, Y and H if the wage per hour (W) will decrease? =

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
