Consumption and Disposable
Income
• Many households live paycheck to
paycheck and will spend money as it comes
in. Thus, consumption is a function of
disposable income which increases with
income.

Investment and Cash Flow
• Financial Accelerator Effect: Download
When business cycle conditions improve,
business cash flow also improves.
Businesses, especially those without access
to financial markets, rely on cash flow for
financing.

Determinants of Gross Private

• Level of real income and output in the
economy
• Real interest rates
• Business taxes
• Expected Profits and Business Confidence
• Capacity utilization rates
• Residential Investment Spending
• Inventory Investment

Multiplier Effect in the Open
Economy
• Multiplier feedback is moderated by international
trade.
• Some of the extra expenditure generated by extra
income/cash flow will be spent on imports and
thus not generate extra demand for domestic
goods.
• Multiplier effect smaller in economies that spend a
high fraction of their income on imported goods.

Expenditure is a Feedback Loop
• Expenditure is determined by household
and corporate income.
• Income is determined by the value added of
output in the economy.
• Output will be determined by demand for
expenditure.

Multiplier Effect
• Changes in autonomous expenditure will
have multiple impacts on output.
• The higher is the marginal propensity to
consume or invest, the larger is that multiple.
• The more open is the economy, the smaller
is that multiple.

Interest and Autonomous
Expenditure
• There is negative relationship between the
real interest rate and consumption and
expenditure.
• Real interest rate, r, is:
– the direct cost of financing corporate
investment, housing, or consumer durables.
– the return on saving and thus the opportunity
cost of consumption.
Interest Sensitive Autonomous
Expenditure
• Define IRE (r ) as the part of expenditure

which is interest sensitiv and NIRE as the noninterest sensitive component.
E0 (r )  IRE (r )  NIRE


• Autonomous expenditure is a negatively
related to the real interest rate. This means
that equilibrium expenditure is negatively
related to expenditure

Learning Outcomes
• Students should be able to name the main
components of expenditure and their
determinants.
• Students should be able to calculate
equilibrium expenditure as a multiple of
autonomous expenditure.
• Use the model of equilibrium expenditure to
explain the effect of events on demand for
goods.
