5. Saving and net flows of capital and goods In a closed economy, saving and investment must be equal, but this is not the case in an open economy. In the following problem, you will explore how saving and investment are connected to the international flow of capital and goods in an economy. Before delving into the relationship between these various components of an economy, you will be asked to recall some relationships between aggregate variables that will be useful in your analysis. Recall the components that make up GDP. National income (Y) equals total expenditure on the economy's output of goods and services. Thus, where C = consumption, I = investment, G = government purchases, X = exports, M = imports, and NX = net exports: Y = Also, national saving is the income of the nation that is left after paying for . Therefore, national saving (S) is defined as: S = Rearranging the previous equation and solving for Y yields Y = . Plugging this into the original equation showing the various components of GDP results in the following relationship: S = This is equivalent to S = , since net exports must equal net capital outflow (NCO, also known as net foreign investment). Now suppose that a country is experiencing balanced trade. Determine the relationships between the entries in the following table, and enter these relationships using the following symbols: > (greater than), < (less than), or = (equal to). Outcomes of Balanced Trade Imports Exports 0 Net Exports Y C+I+G Investment Saving Net Capital Outflow 0

51.The Fed is conducting expansionary monetary policy if it:

A increases the discount rate, buys bonds, and sets a lower target for the federal funds rate.

B decreases the discount rate and sells bonds.

C sets a lower target for the federal funds rate and buys bonds in the open market.

D increases reserve requirements and buys bonds in the open market.

E buys bonds in the open market and raises the discount rate.

52.If banks become concerned about future conditions and decide to hold larger excess reserves, which of the following is a likely result?

A A rise in interest rates

B An increase in bond prices

C An increase in aggregate demand

D An increase in the money supply

E Both C and D

53.The Fed is under no obligation to coordinate its actions with fiscal policy. And in fact, the Fed may take actions specifically designed to counteract some piece of fiscal policy. An example of fiscal and monetary policies with opposite effects is:

A an increase in taxes and increased sales of bonds by the Fed.

B a decrease in government spending and an increase in the discount rate.

C a decrease in taxes and a decrease in the target for the federal funds rate.

D an increase in government spending and an increase in reserve requirements.

E a decrease in taxes and increased purchases of bonds by the Fed.

54.In the fictitious nation of Zagora, a worker can produce either 5 books or 10 televisions in an hour. In neighboring Plovdiv, a worker can produce either 3 books or 5 televisions in an hour. Which statement about this situation is true?

A Zagora has comparative advantage in the production of books.

B Zagora has comparative advantage in the production of televisions.

C Workers in Plovdiv can’t possibly compete against the super-productive workers in Zagora.

D Workers in Zagora can’t be expected to compete against the low-wage workers in Plovdiv.

E None of the above

55.Given the U.S. has a current account deficit, a large increase in the demand for U.S. computer programs among Japanese residents will have all the following effects except:

A an increase in the exchange rate, expressed in yen per dollar.

B an increase in the U.S. capital account surplus.

C an increase in investment in Japan.

D an decrease in the U.S. trade deficit.

E It may have all the above effects.

56.Fiscal policy affects exchange rates because:

A as government spending increases, the government must buy more and more goods and services from foreign countries.

B as government debt increases, interest rates rise, and the value of the currency rises.

C as government debt increases, interest rates rise, and the value of the currency falls.

D as the money supply increases, interest rates fall, and the value of the currency rises.

E as the money supply increases, interest rates fall, and the value of the currency falls.

57.There are many kinds of trade restrictions, and trade restrictions are put into place for many reasons. Which of the following is not a reason to use trade restrictions?

A To save natural habitats from over-use

B To protect the jobs of workers in certain industries

C To make a political statement regarding the labor policies of another nation

D To compensate for higher taxes placed on domestic producers

E To create a lower prices for domestic consumers

58.If the value of the U.S. dollar in foreign exchange markets rises:

A U.S. exports will become relatively less expensive.

B capital inflows into the United States will increase.

C people in the U.S. will purchase fewer imports.

D U.S. exports will likely decrease.

E All of the above

59.Saying that leakages equal injections give the equation:

A T + S + X = G + I + M

B Y = C + S + T

C Y = C + I + G + X - M

D T + S + M = C + G + I + X

E T + S + M = G + I + X

Real GDP (Y) can be decomposed into the sum of spending by consumers (C), firms (I), the government (G) and net exports (X-M). Y = C + I + G + NX. A common approach taken in exploring real GDP developments is to explore how each of these four spending components identified will develop in the near future. For example, if consumer confidence (an example of a forward looking indicator) is increasing, this is usually taken as a signal that C will be increasing at a 'healthy' growth rate in the near future. If consumer confidence is decreasing, then C is expected to be flat. Since the spending components feed into real GDP (go back to the circular flow diagram), the development of C gives some indication about near future developments in real GDP or economic growth. Thus, one can explore expected changes in C, I, G, and NX to get a handle on the expected real GDP growth for the next quarter or year. Your assignment is to develop a report that describes expectations for US RGDP in the short term (6 months to 1 year) and medium term (2 to 3 years). This type of macroeconomic outlook report is important and of interest to every type of business enterprise as it is the basic indicator of future output and input market conditions. Your report should be addressed to someone who has only a basic understanding of economics; thus, you should as part of your report, explain the definition of each of the spending components (an any other technical terms you use). You may use charts and graphs as appropriate. The finished report should be 3 to 5 pages, and include a Executive Summary of no more than 200 words. While you are free to use whatever references you want (please make sure that your report appropriately documents any resources)
