For all the questions below select the appropriate answer:
| a) | If the MPC is 3/4, the net tax rate is 1/3, and the government
increases spending by $100 million, then we would expect the result
to be:
|
| b) | Suppose the MPC and the slope of the AE function are 0.8,
giving a multiplier of 5.0. Then a newly formed government
introduces a net tax on national income, NT = 0.2Y. As a result:
|
| c) | In an open economy with imports described by the import
function: IM = 0.25Y and exports equal to X = 250:
|
| d) | In the diagram NT is tax revenue and G is government expenditure. All figures are in billions. In this economy:
|
| e) | An economy with household, business, government and
international trade sectors is described by the following
equations: Consumption: C = 75 + 0.85(Y - T) Investment: I = 125 Government expenditure: G = 75 Net taxes: NT = 0.2Y Exports: X = 25 Imports: IM = 0.18Y The multiplier, the equilibrium level of real GDP and the government's budget balance in this economy would be:

It appears that not all people are equally vulnerable to cancer. People from some ethnic groups have higher or lower than average chances of developing certain types of cancer. Jennifer’s manager Dr. Steinberg thinks that the company’s insurance policy should reflect this fact and constantly raises this question in the meetings. To be more convincing, he asked Jennifer Nguyen to take a random sample of those Healthy Life clients who belong to ethnic group X (at least on their maternal or paternal side) and a similar sample consisting of the clients without X ancestry. Then, Jennifer was asked to compare clients’ Y parameters indicating likelihood of developing W cancer. (As the matter is ticklish, we will not be naming the ethnic group, the type of cancer, the medical parameter, and the gender of sample members.) Then, it is known that in the general population Y parameters are distributed with the standard deviation of 3.0 (therefore the population variance is equal to 9.0). However in the X ethnic group the population standard deviation is about 2.1(and the population variance is equal to 4.41). As only 2-3% of Canadians have X ancestors, Jennifer and her manager assume that the standard deviation in the population of those who have no X ancestry is also around 3.0 as in the country in general. This assumption allows using z-distribution. The data are provided. Can we state at 1% level of significance that it matters whether a person belongs to X group or not in terms of the risk of developing W cancer? Or the chances are equal (on average Y parameters are the same)? Help Jennifer Nguyen to conduct the test. Use Data Analysis z-Test: Two-Sample for Means.

You are an executive in a large healthcare company with five lines of business. There are no economies of scope (this will be discussed in a future module). Those lines of business order services (accounting, information technology, and warehousing) from three "service divisions" of the company. You are given the following information for the revenues, direct costs (e.g., costs of production), and capital (e.g., value of the property, plant, and equipment) associated with these five lines of business, as well as the total variable costs from the three 'internal services' divisions. (You are ignoring fixed corporate overhead costs which will not change with a change in the size of the company.) All dollar amounts are in millions of dollars.
As an executive in this company you are concerned with the following: (1) the businesses have little incentive to reduce their request for services from the three service divisions; (2) the service divisions are unable to tie their requested budgets to the value of their services; and (3) some of the businesses may have low returns on capital and should be sold off. To initially address these issues you are imposing an internal pricing system, where each of the three service divisions charges the businesses for the services provided. The expected percentage allocation of the variable costs from each to service division to each business are given in the matrix below. Notice that the sum of any allocations from a service division sum to 1.0.
Use this information to allocate the service divsions' variable costs to the five businesses. Recalculate the return on capital for each of the five businesses. You will enter this information, to three decimal places, in Moodle. Suppose that the market rate of return for similarly risky investments is 14 percent. If you took the approach of Goizueta at Coca-Cola, which businesses should be sold? |

e.g. 1: a parcel with volume 4, the cost is $3+ $1 +$1 +$1 = $6
