1.If the household does not change its consumption of
gasoline,it will be unaffected by the tax-rebate program,
because in this case the household pays 0.20*800=$160 in
taxes and receives $160 as an annual tax rebate.The two
effects would cancel each other out.To the extent that the
household reduces its gas consumption through substitution,
it must be better off.The new budget line (price change
plus rebate) will pass through the old consumption point of
800 gallons of gasoline,and any now affordable bundle that
contains less gasoline must be on a higher indifference curve.
The household will not choose any bundle with more gasoline
because these bundles are all inside the old budget line,and
hence are inferior to the bundle with 800 gallons of gas.
2.In filling a vacant position,you should be concerned
with the marginal product of the last worker hired because
the marginal product measures the effect on output,or total
product,of hiring another worker.This in turn will help to
determine the revenue generated by hiring another worker,
which can then be compared to the cost of hiring another
worker.
The point at which the average product begins to decline is
the point where average product is equal to marginal
product.When average product declines,the marginal
product of the last worker hired is lower than the average
product of previously hired workers.
Although adding more workers results in a further decline in
average product,total product continues to increase,so it
may still be advantageous to hire another worker.

1. 如果一户家庭不改变他的汽油消费,那么他将不会受到退税的影响,因为在这种情况下,每户需支付0.20 × 800 = 160美元的税款,以及每年160美元的退税,这两个影响将相互抵消.在一定程度上说,家庭通过替代减少天然气消费量,他的境况会变得更好.新的预算线（价格变化和退税）将通过800加仑汽油这个旧的消费点,现在消费较少汽油的消费束一定在更高的无差异曲线上.
家庭不会选择消费更多汽油的消费束,因为这些消费束在旧预算线以内,次于800加仑的汽油消费束.
2. 在填补一个空缺职位的过程中,你应该主意最后一个雇佣工人的边际产量,因为边际产品测度的是雇佣其他工人对产出或总产量的影响.反过来这将有助于确定雇佣其他工人的收益,然后与雇佣其他工人的成本相比.
平均产量开始下降的点是平均产量等于边际产量的点,当平均产量下降时,最后的雇佣工人的边际产量低于以前的雇佣工人的平均产量.
尽管雇佣更多的工人会引起平均产量的进一步下降,但总产量继续增加,所以继续雇佣工人可能仍然是有利的
