Expert Solution

1. Savings should be equal to Investment - Classical economists believe that interest rate brings the equality between savings and investment. If there is excess of saving then interest rate will fall down thereby increasing investment and dropping in savings till the point of equilibrium is achieved. Same way if savings are less then interest rate will move up so as to increase savings till the equilibrium point is achieved.

This means that economy will operate at full employment levels. However this idea got rejected later.

2. 2 sector model in economy is assumed: Only households are producers are there. Aggregate expenditure will depend upon (Consumption + Investment) and national income equals (Saving + Consumption). Therefore Savings will be equal to Investment.

Explain the relationship among output, saving, and investment. Suppose depreciation per worker is less than saving per worker. Given this situation, explain what will happen to each of the following variables over time: capital per worker, output per worker, saving per worker, and consumption per worker. During the latter half of the 1990s, the U.S. saving rate decreased. Will this reduction in the saving rate have a permanent effect on the rate of growth of output per worker? Explain. Graphically...

1. First, write out the equilibrium conditions in the Goods and Services market and the Loanable Funds Market for a closed economy (i.e. the “supply equals demand” equations for each). 2. As we’ve learned, a third market – the Labor Market – typically does not reach an equilibrium where supply of labor equals demand for labor. What do we call the “normal” unemployment rate that persists even when wages have [incompletely] adjusted? 3. Say that businesses in the economy collectively...
