We shall examine the impact of investment on the economy in the context of the model of aggregate demand and aggregate supply. Investment is a component of aggregate demand; changes in investment shift the aggregate demand curve by the amount of the initial change times the multiplier.

Macroeconomics is the study of the behavior of the economy as a whole. This is different from microeconomics, which concentrates more on individuals and how they make economic decisions. While microeconomics looks at single factors that affect individual decisions, macroeconomicsstudies general economic factors. Macroeconomics is very complicated, ...
Output, the most important concept of macroeconomics, refers to the total amount of goods and services a country produces, commonly known as the gross domestic product (GDP). This figure is like a snapshot of the economy at a certain point in time. When referring to GDP, macroeconomists tend to use real GDP, which takes inflation into account, as o...
The unemployment ratetells macroeconomists how many people from the available pool of labor (the labor force) are unable to find work. Macroeconomists agree when the economy witnesses growth from period to period, which is indicated in the GDP growth rate, unemployment levels tend to be low. This is because, with rising (real) GDP levels, we know t...
The third main factor macroeconomists look at is the inflation rate, or the rate at which prices rise. Inflation is primarily measured in two ways: the Consumer Price Index (CPI) and the GDP deflator. The CPI gives the current price of a selected basket of goods and services that is updated periodically. The GDP deflatoris the ratio of nominal GDP ...
What ultimately determines output is demand. Demand comes from consumers, from the government, and from imports and exports. Demand alone, however, will not determine how much is produced. What consumers demand is not necessarily what they can afford to buy, so to determine demand, a consumer's disposable incomemust also be measured. This is the am...
There are two ways the government implements macroeconomic policy. Both monetary and fiscal policy are tools the government uses to help stabilize a nation's economy. Below, we take a look at how each works.
The performance of the economy is important to all of us. We analyze the economy by primarily looking at the national output, unemployment, and inflation. Although it is consumers who ultimately determine the direction of the economy, governments also influence it through fiscal and monetary policy.
- Interest rates. Investment is financed either out of current savings or by borrowing. Therefore investment is strongly influenced by interest rates. High interest rates make it more expensive to borrow.
- Economic growth. Firms invest to meet future demand. If demand is falling, then firms will cut back on investment. If economic prospects improve, then firms will increase investment as they expect future demand to rise.
- Confidence. Investment is riskier than saving. Firms will only invest if they are confident about future costs, demand and economic prospects. Keynes referred to the ‘animal spirits’ of businessmen as a key determinant of investment.
- Inflation. In the long-term, inflation rates can have an influence on investment. High and variable inflation tends to create more uncertainty and confusion, with uncertainties over the future cost of investment.
Investments, and the factors influencing investments, are a central component of any macroeconomic theory. In macroeconomic models, investments are described by an investment function, i.e. a behavioural equation that shows the dependence of aggregate investment demand on other variables.
In some research, investment is modeled as an increasing function of the gap between the optimal capital stock and the current capital stock. Here the optimal capital stock is modeled as that which maximizes profit.
This section examines eight additional determinants of investment demand: expectations, the level of economic activity, the stock of capital, capacity utilization, the cost of capital goods, other factor costs, technological change, and public policy.
