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).

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).
