This is opposite to the reactivity order observed for the SN2 mechanism. Allylic and benzylic halides are exceptionally reactive by either mechanism. Fourth, in order to facilitate the charge separation of an ionization reaction, as required by the first step, a good ionizing solvent will be needed.

So part of the temporary increase in income is consumed and part is saved. So a rise in future income leads to an increase in current consumption but a decrease in saving.

So an increase in wealth increases current consumption and decreases saving. So consumption and saving are the same in each period as in part 1 above.

So cl is constrained to be The effect on saving depends on whether the marginal propensity to consume MPC of veterans differs from that of the general population.

If there is no difference in MPCs, there will be no shift of the saving curve; neither investment nor the real interest rate is affected.

The Economy: Leibniz: Mathematics of income and substitution effects

If the MPC of veterans is higher than the MPC of the general population, then desired national saving declines and the saving curve shifts to the left; the real interest rate rises and investment declines. If the MPC of veterans is lower than that of the general population, the saving curve shifts to the right; the real interest rate declines and investment rises.

Saving and investment increase, as does the real interest rate. The rise of the future marginal productivity of capital shifts the investment curve to the right.

The result, as shown in Figure 4. Then the new equilibrium point is one with lower employment and a lower real wage. With lower employment and a lower capital stock, full-employment output will be lower.

On the other hand, since future output is also lower, people desire to save more today to make up for the loss of future income. Then the new equilibrium assuming no change in desired saving is at a higher level of investment and a higher real interest rate.

At equilibrium, there is a reduced real wage and lower employment. Because the shock is temporary, the only effect on desired saving or investment is due to the reduction in current output, causing desired national saving to fall. This shifts the saving curve to the left, raising the real interest rate and reducing the level of desired investment, as well as desired national saving, as shown in Figure 4.

The productivity shock results in a reduction of current output. Because the shock is permanent, it reduces future output as well, and reduces the future marginal product of capital.

The desired investment curve shifts to the left, from I1 to I2 in Figure 4. The effect on desired saving is ambiguous—the reduction in current income reduces desired saving, but the reduction in expected future income increases desired saving.

Then national saving and investment both decline. Again, the effect on the real interest rate is ambiguous. Alternatively, if the effects on desired saving of the reductions in current income and future income offset each other exactly, the desired saving curve does not shift. In this case, the leftward shift of the investment curve along an unchanged saving curve reduces the real interest rate, saving, and investment.

A temporary increase in government spending reduces national saving. Whether the spending is financed by current taxes or by borrowing and raising future taxesconsumption falls, but not by the full amount of the spending. This is shown in Figure 4. It makes no difference whether the temporary increase in spending is funded by taxes or by borrowing.

With upward shifts in both saving and investment, the new equilibrium is one with a higher real interest rate. However, saving and investment at the new equilibrium may be higher or lower. The effect on consumption is unclear as well. The higher real interest rate reduces consumption, but future income is higher, which increases consumption.

When there is a temporary increase in government spending, consumers foresee future taxes. As a result, consumption declines, both currently and in the future. Thus the real interest rate increases and consumption and investment both fall. But if there is an equal increase in current and future government spending, and consumers try to smooth consumption, they will reduce their current and future consumption by about the same amount, and that amount will be about the same amount as the increase in government spending.

So the saving curve in the saving-investment diagram does not shift, and there is no change in the real interest rate. Since the saving curve shifts upward more in the case of a temporary increase in government spending, the real interest rate is higher, so investment declines by more.Introduction.

The growing evidence of the negative health effects of sugar sweetened drinks has led to calls for action to limit consumption.1 2 Several options exist, including controls on the marketing of sugar sweetened drinks, limits on portion sizes, and taxation.3 In the United Kingdom, the sale of sugar sweetened drinks in schools and their advertisement during children’s television.

a) Use the concepts of income effect and substitution effect to explain why an increase in lump-sum taxes will increase the amount of labor supplied. (a) If the lump-sum tax is increased, there’s an income effect on labor supply, not a substitution effect (since the real wage isn’t changed).

Small income effect, small substitution effect: The amount of income that is spent on salt is relatively small, but since there are few substitutes for salt, consumers will not readily substitute away from it.

As the price of salt rises, real income will fall only slightly, thus leading to a small decline in consumption.
