## What causes the investment function to shift?

A **change in any other determinant of investment** causes a shift of the curve. The other determinants of investment include expectations, the level of economic activity, the stock of capital, the capacity utilization rate, the cost of capital goods, other factor costs, technological change, and public policy.

## What does the investment function show?

Aggregate Expenditure: Investment as a Function of National Income. Just as a consumption function shows the relationship between real GDP (or national income) and consumption levels, the investment function shows **the relationship between real GDP and investment levels**.

## What is the theory of liquidity preference How does it help explain the downward slope of the aggregate demand curve?

The theory of liquidity preference explains the downward slope of aggregate demand and supply as well as the **role of monetary policy in shifting aggregate demand curve**. According to Keynes the interest rate adjusts to bring money supply and money demand into balance.

## What factors shift the investment function and why is it so unstable?

Raising the money supply simply pushes up prices. Saving and investment are brought into equilibrium by changes in income. Investment is unstable **because it is strongly influenced by expectations of the future, which is uncertain**.

## What causes the investment demand curve to shift to the left?

As expectations change in a way that increases the expected return from investment, the investment demand curve shifts to the right. Similarly, **expectations of reduced profitability** shift the investment demand curve to the left. Firms need capital to produce goods and services.

## Why is the AD curve downward sloping quizlet?

Why is the aggregate demand curve downward sloping? The aggregate demand curve is downward sloping **because of the real wealth effect, the interest rate effect, and the open economy effect**. … A change in the price level causes a movement along the aggregate demand curve.

## Is a downward slope negative or positive?

Straight lines that are downward sloping **have negative slopes**; curves that are downward sloping also have negative slopes. We know, of course, that the slope changes from point to point on a curve, but all of the slopes along these two curves will be negative.

## What causes the downward swivel of an aggregate expenditure curve?

An increase in income tax rates will make the aggregate expenditures curve flatter and reduce the multiplier. **A higher income tax rate** thus rotates the aggregate expenditures curve downward. Similarly, a lower income tax rate rotates the aggregate expenditures curve upward, making it steeper.

## What is investment function discuss the factors affecting investment function?

Factors like **prices, wages and interest changes** which affect profits influence induced investment. Similarly demand also influences it. When income increases, consumption demand also increases and to meet this, investment increases. In the ultimate analysis, induced investment is a function of income i.e., I = f(Y).
