According to thisâ theory, what happens after a temporary increase in government purchases to each of the followingâ variables? a. Employment
b. The real wage
c. Average labor productivity
d. Investment
e. The price level

The answer is given below

Explanation:

The IS-LM model, simply is an acronym which represents "investment-savings" and the "liquidity preference of money supply". The model indicates the interaction between market for economic goods and the loanable funds market which is also called the money market.

The variables are explained below:

a. Employment: A rise in the spending expenditure will result into an increase in the current or future taxes which will have an effect on the workers by making them poorer and therefore making them offer their services to the labor market. This will lead to a rise in labor supply.

b. The real wage: Due to the increase in labor supply, the real wage will reduce because the supply of labor will be more than the demand.

c. Average labor productivity: The marginal productivity of labor or production function is not influenced by fiscal policy changes.

d. Investment: There will be a leftward upward shift of the LM curve. Due to increase in price of goods and services, and the fall in real money supply, the interest rate will rise therefore making investment to reduce.

e. The price level: Demand for output is more than the full employment level of output. This will bring about increase in price.
