When someone owns an asset (such as a share of stock) that rises in value, he has an “accrued” capital gain. If he sells the asset, he “realizes” the gains that have previously accrued. Under the U.S. income tax, realized capital gains are taxed, but accrued gains are not.

b. Some economists believe that cuts in capital gains tax rates, especially temporary ones, can raise tax revenue. How might this be so?
c. Do you think it is a good rule to tax realized but not accrued capital gains? Why or why not?
