Fig 1

In the above figure, vertical axis shows interest rate and horizontal axis shows quantity of loanable funds.
andrepresents demand and supply curve for loanable funds respectively. The intersection of demand and supply curve gives equilibrium point where the interest rate is and quantity of funds is
Due to reduction in deficit the demand curve will shift from toThere is no change in supply curve. The new equilibrium is achieved at point where the new interest rate isand. quantity of fund demanded is Hence, interest rate as well as quantity of loanable fund decreases at new level of equilibrium.
Due to decrease in interest rate and income, private savings will decrease as the opportunity cost of saving has decreased. Private investment spending will increase because at lower interest rate people will borrow more to invest.

Conclusion:

Thus, private saving and interest rate decreases and private investment spending increases.

b. Consumers save more.

Due to increase in saving by consumer supply curve will shift from toThere is no change in demand curve. The new equilibrium is achieved at point where the new interest rate isand. quantity of fund demanded isHence, interest rate has decreased and quantity has increased at new level of equilibrium.
Due to decrease in interest rate private savings will decrease as the opportunity cost of saving has decreased and due to increase in output income will increase which will induce more saving.
Hence, savings will increase or decrease, this cannot be concluded. Private investment spending will increase because at lower interest rate people will borrow more to invest.

Conclusion:

Thus, interest rate decreases and private investment spending increases. Private saving may decrease or increase.

Due to an increase in interest rate, income private savings will increase as the opportunity cost of saving has increased. Private investment spending will decrease because at higher interest rate people will borrow less to invest.

Conclusion:

Thus, private saving and interest rate increases and private investment spending decreases.

1. Suppose that the two nations face the following benefits of pollution, B, and costs of abatement, C: BN = 10, Bs = 7; CN = 5, Cs = 4. Further assume that if the nation chooses to abate pollution, it still receives the benefits of pollution but now must pay the cost of abatement as well. a. Identify the payoffs that accrue to each nation under the four different possible outcomes of the game and present these payoffs in the normal form of the game. b. Recall that the term dominant strategy defines the condition that a player in a game would prefer to play that strategy (in this case either pollute or abate) regardless of the strategy chosen by the other player in the game. Does either nation have a dominant strategy in this game? If so, what is it? c. Identify the Nash equilibria, or non-cooperative equilibria, of this game.

The new equilibrium is achieved at point where the new interest rate isand. quantity of fund demanded is Hence, interest rate as well as quantity of loanable fund decreases at new level of equilibrium.
Due to decrease in interest rate and income, private savings will decrease as the opportunity cost of saving has decreased. Private investment spending will increase because at lower interest rate people will borrow more to invest.

Conclusion:

Thus, private saving and interest rate decreases and private investment spending increases.

b. Consumers save more.

In the above figure, vertical axis shows interest rate and horizontal axis shows quantity of loanable funds.
andrepresents demand and supply curve for loanable funds respectively. The intersection of demand and supply curve gives equilibrium point where the interest rate is and quantity of funds is
Due to increase in saving by consumer supply curve will shift from toThere is no change in demand curve. The new equilibrium is achieved at point where the new interest rate isand. quantity of fund demanded isHence, interest rate has decreased and quantity has increased at new level of equilibrium.
Due to decrease in interest rate private savings will decrease as the opportunity cost of saving has decreased and due to increase in output income will increase which will induce more saving.
Hence, savings will increase or decrease, this cannot be concluded. Private investment spending will increase because at lower interest rate people will borrow more to invest.

Conclusion:

Thus, interest rate decreases and private investment spending increases. Private saving may decrease or increase.

c. Businesses become optimistic for future profitability.

andrepresents demand and supply curve for loanable funds respectively. The intersection of demand and supply curve gives equilibrium point where the interest rate is and quantity of funds is
Businesses are optimistic about future profitability which means that the investment will increase. This will lead to rise in demand for loanable fund. As a result the demand curve will shift from to
There is no change in supply curve. The new equilibrium is achieved at point where the new interest rate isHence, interest rate as well as quantity of loanable fund increases to a new level of equilibrium.
Due to an increase in interest rate, income private savings will increase as the opportunity cost of saving has increased. Private investment spending will decrease because at higher interest rate people will borrow less to invest.

Conclusion:

Thus, private saving and interest rate increases and private investment spending decreases.
