If not, that's probably the best google query for you to start learning more. My question to you is how do you know that the rise in interest rates wasn't from a "shift in investment" in the sense that at any interest rate firms are now investing relatively more than beforehand?

People would save more, the interest rate would be higher, and investment would also be higher. However, suppose the price of apples rises and apple sellers supply more apples. However, apple buyers will buy less so quantity demanded of apples will decrease. Hence quantity demanded is less than quantity supplied now. It might not be perfectly stated, but presuming that the interest rate rise is coming from the central bank this is a very deep and difficult question that most economists would struggle to answer.

Case 2: sticky prices. Improve this answer. Can there be exogenous shocks to prices? FooBar FooBar So people does not have as much income as before when the interest rate has not rose, so their saving is clearly also decreased.

Do you think it is an valid argument? Typically, investment now yields additional production in the future - there is some delay. Hence, a decrease in investment today will not decrease income today, but rather a decrease in income tomorrow. I mean the production of capital instead of what can be produced by the capital in the future. When a rise in interest rates causes less desired investment and more desired savings meaning less desired consumption , income will fall and keep falling until savings decline enough to restore equilibrium.

That extra financial capital will be invested abroad.

This connection of domestic saving and investment to the trade balance explains why economists view the balance of trade as a fundamentally macroeconomic phenomenon. As the national saving and investment identity shows, the performance of certain sectors of an economy, like cars or steel, do not determine the trade balance. The national saving and investment identity also provides a framework for thinking about what will cause trade deficits to rise or fall.

Begin with the version of the identity that has domestic savings and investment on the left and the trade deficit on the right:. Now, consider the factors on the left-hand side of the equation one at a time, while holding the other factors constant. As a first example, assume that the level of domestic investment in a country rises, while the level of private and public saving remains unchanged. Since the equality of the national savings and investment identity must continue to hold—it is, after all, an identity that must be true by definition—the rise in domestic investment will mean a higher trade deficit.

This situation occurred in the U. Because of the surge of new information and communications technologies that became available, business investment increased substantially. A fall in private saving during this time and a rise in government saving more or less offset each other. As a result, the financial capital to fund that business investment came from abroad, which is one reason for the very high U.

As a second scenario, assume that the level of domestic savings rises, while the level of domestic investment and public savings remain unchanged. In this case, the trade deficit would decline. As domestic savings rises, there would be less need for foreign financial capital to meet investment needs. For this reason, a policy proposal often made for reducing the U. As a third scenario, imagine that the government budget deficit increased dramatically, while domestic investment and private savings remained unchanged.

This scenario occurred in the U. The connection at that time is clear: a sharp increase in government borrowing increased the U. The following Work It Out feature walks you through a scenario in which private domestic savings has to rise by a certain amount to reduce a trade deficit. Step 1. Write out the savings investment formula solving for the trade deficit or surplus on the left:. Step 2. In the formula, put the amount for the trade deficit in as a negative number X — M.

The left side of your formula is now:. Step 5. The government budget surplus or balance is represented by T — G. Enter a budget deficit amount for T — G of — The question is: To reduce your trade deficit X — M of — to — in billions of dollars , by how much will savings have to rise? Step 7.

In the short run, whether an economy is in a recession or on the upswing can affect trade imbalances. A recession tends to make a trade deficit smaller, or a trade surplus larger, while a period of strong economic growth tends to make a trade deficit larger, or a trade surplus smaller.

As an example, note in [link] that the U. One primary reason for this change is that during the recession, as the U. However, buying power abroad fell less, and so U. Conversely, in the mids, when the U. As a result, there was considerable aggressive buying in the U. Thus, a trade deficit or a much lower trade surplus often accompanies a rapidly growing domestic economy, while a trade surplus or a much lower trade deficit accompanies a slowing or recessionary domestic economy.

When the trade deficit rises, it necessarily means a greater net inflow of foreign financial capital. The national saving and investment identity teaches that the rest of the economy can absorb this inflow of foreign financial capital in several different ways. For example, reduced private savings could offset the additional inflow of financial capital from abroad, leaving domestic investment and public saving unchanged.

Alternatively, the inflow of foreign financial capital could result in higher domestic investment, leaving private and public saving unchanged. Yet another possibility is that greater government borrowing could absorb the inflow of foreign financial capital, leaving domestic saving and investment unchanged.

The national saving and investment identity does not specify which of these scenarios, alone or in combination, will occur—only that one of them must occur. The national saving and investment identity is based on the relationship that the total quantity of financial capital supplied from all sources must equal the total quantity of financial capital demanded from all sources.

If S is private saving, T is taxes, G is government spending, M is imports, X is exports, and I is investment, then for an economy with a current account deficit and a budget deficit:. A recession tends to increase the trade balance meaning a higher trade surplus or lower trade deficit , while economic boom will tend to decrease the trade balance meaning a lower trade surplus or a larger trade deficit.

Using the national savings and investment identity, explain how each of the following changes ceteris paribus will increase or decrease the trade balance:. If domestic savings increases and nothing else changes, then the trade deficit will fall. In effect, the economy would be relying more on domestic capital and less on foreign capital. If the government starts borrowing instead of saving, then the trade deficit must rise. In effect, the government is no longer providing savings and so, if nothing else is to change, more investment funds must arrive from abroad.

If the rate of domestic investment surges, then, ceteris paribus, the trade deficit must also rise, to provide the extra capital. In all of these situations, there is no reason to expect in the real world that the original change will affect only, or primarily, the trade deficit. The identity only says that something will adjust—it does not specify what.

If a country is running a government budget surplus, why is T — G on the left side of the saving-investment identity? If domestic investment increases, and there is no change in the amount of private and public saving, what must happen to the size of the trade deficit? Both the United States and global economies are booming. Will U.
