Companies encourage their employees to hold stock in the pany because it gives the employees the incentive to care about the firm’s profits, not just their own salary. Then, if employees see waste or see areas in which the firm can improve, they’ll take actions that benefit the pany because they know the value of their stock will rise as a result. And it also gives employees an additional incentive to work hard, knowing that if the firm does well, they will profit.But from an employee’s point of view, owning stock in the pany for which she or he works can be risky. The employee’s wages or salary are already tied to how well the firm performs. If the firm has trouble, the employee could be laid off or have her or his salary reduced. If the employee owns stock in the firm, then there’s a double whammy190。the employee is unemployed or gets a lower salary and the value of the stock falls as well. So owning stock in your own pany is a very risky proposition. Most employees would be better off diversifying190。owning stock or bonds in other panies190。so their fortunes wouldn’t depend so much on the firm for which they work. 5. To a macroeconomist, saving occurs when a person’s ine exceeds her consumption, while investment occurs when a person or firm purchases new capital, such as a house or business equipment.a.

When you use your $200 paycheck to buy stock in ATamp。T, that’s saving, because your ine of $200 isn’t being spent on consumption goods.c. When your roommate earns $100 and deposits it in her account at a bank, that’s saving, because the money isn’t spent on consumption goods.d. When you borrow $1,000 from a bank to buy a car to use in your pizzadelivery business, that’s investment, because the car is a capital good. 6. We’re given the numbers Y = 8, T = , Sprivate = = Y T C, Spublic = = T G. Since Sprivate = Y T C, then rearranging gives C = Y T Sprivate = 8 = 6. Since Spublic = T G, then rearranging gives G = T Spublic = = .Since S = national saving = Sprivate + Spublic = + = .Finally, since I = investment = S, I = . 8. a. Figure 252 illustrates the effect of the $20 billion increase in government borrowing. Initially, the supply of loanable funds is curve S1, the equilibrium real interest rate is i1, and the quantity of loanable funds is L1. The increase in governmen
