2. Income statement

The income statement, also known as the profit and loss (P&L) statement, provides a snapshot of the financial performance of a company during a specified period of time. It reports a firm’s gross income, expenses, net income, and the income that is available for distribution to its preferred and common shareholders.

The income statement is prepared using the generally accepted accounting principles (GAAP) that match the firm’s revenues and expenses to the period in which they were incurred, not necessarily when cash was received or paid. Investors and analysts use the information given in the income statement and other financial statements and reports to evaluate the company’s financial performance and condition.

Consider the following scenario:

Green Caterpillar Garden Supplies Inc.’s income statement reports data for its first year of operation. The firm’s CEO would like sales to increase by 25% next year.

Complete the Year 2 income statement data for Green Caterpillar, then answer the questions that follow. Be sure to round each dollar value to the nearest whole dollar.

Given the results of the previous income statement calculations, complete the following statements:

Genetic change in bacteria can be brought about by conjugation
transduction.
vertical gene transfer.

The world comprises two countries, A and B. There is only one good, whose price is normalized to 1; hence nominal and real measures coincide. These two countries differ with respect to their production technology. In particular, ???? = 10 − 0.8?? and ???? = 7 − 0.7??, where ???? denotes the marginal product of capital and ?? the capital stock in country i = Α, Β. The total capital stock in the world is 10 units.

a) The initial allocation of capital is ?? = 5 and ?? = 5. Find each country’s total income as well as labor and capital income. What is the world income? [Mark: 0.75]

b) Next, consider the case where there is free capital mobility. Find the capital allocation between the two countries, each country’s total income, as well as labor and capital income. What happens to world income? Explain your answers. [Mark: 0.75]

c) Assume now that, succumbing to domestic pressure, the government of country A imposes a 30% tax on capital income. Show graphically the equilibria before and after taxation. Find the new capital allocation between the two countries, total income, tax revenue, as well as labor and net capital income in each country. Explain your answers. [Mark: 1.5] Note: Round your answers to the second decimal point.

Discuss the three types of communication in IPv4 network

1. Assume that GDP is Y = 150. Consumption is C = 50 + .8(Y-T), Investment is I = 100 – 500r, where r is the real interest rate. Taxes are T = 50 and government expenditures are G =20.
   1. Calculate the equilibrium values of C, I, and r.
   2. Calculate the equilibrium values of private saving, government saving, and total saving.
   3. Now suppose due to a war there is an increase in Government expenditures to G=70 without a corresponding increase in taxes (aka it is funded by deficit spending). Calculate C, I, and r.
   4. Calculate the new equilibrium values of private saving, government saving, and total saving.
   5. What happened as a result of the deficit funded ↑ in G? Think of which values have actually changed, was this discussed in class previously?

b. Are getters normally declared const?
c. Are setters normally declared const?
d. Can a const function call a non-const function?
