基本解釋

That slope is the marginal propensity to consume.
這個斜率就是邊際消費傾曏。
It is about the marginal propensity to consume (MPC), which is the extra consumption generated by a dollar of extra income.
而是與邊際消費傾曏（MPC）有關(guān)，即收入每增加一美元帶來的相應消費增量。
The more tax breaks and transfers go to those with a greater marginal propensity to consume, the bigger the economic boost.
有更高消費傾曏的人獲得的稅收減免越多，對經(jīng)濟的提振作用就越大。

If the marginal propensity to consume were 100 percent, there would be no investment, and, soon, no income.
