Economic Considerations
Business investment is of significant interest to economists
because it can affect the short-term and long-term growth of
the economy.
In the short term, an increase in business investment
directly increases the contemporary level of gross domestic
product (GDP), because business investment is included in
GDP. Similarly, a decrease in business investment will
decrease GDP. Business investment is one of the more
volatile components of GDP and tends to fluctuate
significantly from quarter to quarter.
In the long term, business investment, specifically the size

of the capital stock, can impact the long-term growth of the

Saving and Investment
One of the long-term determinants of business investment is
the level of savings available to the economy. For financial
institutions to loan funds to businesses that the businesses
in turn use to make investments, other individuals must be
depositing their savings into those financial institutions.
Because of the global nature of the U.S. economy, firms in
the United States have access to savings from within the
United States and from abroad; thus, interest rates in the
United States are influenced by the supply of global in
addition to national savings. A higher supply of savings
results in lower interest rates, and a lower supply of savings
results in higher interest rates, all else equal. As such, an
increase in the supply of savings should lead to an increase
