ECON 105 Lecture Notes - Lecture 12: Exchange Rate, Price Level, Money Supply

An economy with zero net exports is described below:

A. Find short-run equilibrium output.

Instruction: Enter your response as an integer value.

Short-run equilibrium output: .

B. Economic recovery abroad increases the demand for the country's exports; as a result, NX rises to 80.

Instruction: Enter your response as an integer value.

Short-run equilibrium output (Click to select)decreases/ increases to ________ .

C. Assume that foreign economies are slowing, reducing the demand for the country's exports so that NX = -80. (A negative value of net exports means that exports are less than imports.)

Instruction: Enter your response as an integer value.

Short-run equilibrium output (Click to select)increases/decreases to ___________ .

D. Which of the following best describes the tendency of recessions and expansions to spread across countries?

1. Lower planned aggregate spending in one nation will reduce the amount of goods it exports abroad, thereby lowering the value of imports for its trading partners, which will reduce its short-term equilibrium output as well.

2. Lower planned aggregate spending abroad means that fewer goods will be exported from a specific nation, leaving more goods available for domestic consumption (C) in that nation, which will increase its short-term equilibrium output.

3. Lower planned aggregate spending abroad will reduce the amount of investment that flows into domestic industries from other countries, thereby reducing domestic short-term equilibrium output.

4. Lower planned aggregate spending in a nation means fewer imports of foreign goods, thereby reducing the short-term equilibrium output of its trading partners through lower net export (NX) values in those nations.

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

An open economy interacts with the rest of the world through its involvement in world markets for goods and services and world financial markets. Although it can often result in an imbalance in these markets, the following identity must remain true:

In other words, if a transaction directly affects the left side of this equation, then it must also affect the right side. The following problem will help you understand why this identity must hold.

Suppose you are a software engineer living in the United States, and you just sold your latest product to a Russian consumer for RUB 7,000.

Determine the effects of this transaction on exports, imports, and net exports in the U.S. economy, and enter your results in the following table. If the direction of change is "No change," enter "0" in the Magnitude of Change column.

Hint: The magnitude of change should always be positive, regardless of the direction of change.

Because of the identity equation that relates to net exports, the in U.S. net exports is matched by in U.S. net capital outflow. Which of the following is an example of how the United States might be affected in this scenario? Check all that apply.

You store the rubles in your safety deposit box at home.

You purchase RUB 7,000 worth of stock in a Russian corporation.

You buy RUB 7,000 worth of Russian bonds.
