marginal propensity

基本解释

That slope is the marginal propensity to consume.
这个斜率就是边际消费倾向。
It is about the marginal propensity to consume (MPC), which is the extra consumption generated by a dollar of extra income.
而是与边际消费倾向（MPC）有关，即收入每增加一美元带来的相应消费增量。
The more tax breaks and transfers go to those with a greater marginal propensity to consume, the bigger the economic boost.
有更高消费倾向的人获得的税收减免越多，对经济的提振作用就越大。

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