It remains unclear how long the current investment environment will last in Silicon Valley.

目前尚不清楚这种投资环境会在硅谷持续多久。

That is to say, the addition to the carry-over is an addition to current investment.

也就是说，对结转的追加是对当期投资的追加。

That is to say, what is taken from the carry-over involves a corresponding reduction in current investment.

也就是说，从结转中提取的部分涉及当前投资的相应减少。

For the amount of this excess neither directly gives rise to current investment nor is available to pay for consumption.

因为这个超额部分既不能直接引起经常性投资， 也不能用于支付消费。

It follows that the aggregate saving of the first individual and of others taken together must necessarily be equal to the amount of current new investment.

因此，第一个人和其他人的总储蓄必然等于当前新投资的数额。

For the 'marginal efficiency of capital' partly depends on the scale of current investment, and we must already know the rate of interest before we can calculate what this scale will be.

因为“资本的边际效率”部分取决于当前投资的规模，而我们必须已经知道利率才能计算出这个规模。

The sum has three moving parts: the value of the current investment pot, the discount rate used to calculate the present value of future payouts, and the stream of those expected future payments.

该总和包含三个移动部分： 当前投资底池的价值、用于计算未来支出现值的贴现率， 以及这些预期未来支出的流。

Even to-day it is important to pay close attention to the part played by changes in the stocks of raw materials, both agricultural and mineral, in the determination of the rate of current investment.

即使在今天，密切关注原材料（包括农业和矿产）库存的变化在确定当前投资率方面所起的作用也很重要。

But the daily revaluations of the Stock Exchange, though they are primarily made to facilitate transfers of old investments between one individual and another, inevitably exert a decisive influence on the rate of current investment.

但是，证券交易所的每日重估，虽然主要是为了促进个人之间旧投资的转移，但不可避免地对当前投资率产生决定性影响。

Thus, to justify any given amount of employment there must be an amount of current investment sufficient to absorb the excess of total output over what the community chooses to consume when employment is at the given level.

因此，要证明任何给定就业量的合理性，必须有一定数量的当前投资足以吸收总产出超过社区在给定就业水平时选择消费的部分。

The remedy would lie in various measures designed to increase the propensity to consume by the redistribution of incomes or otherwise; so that a given level of employment would require a smaller volume of current investment to support it.

补救办法在于采取各种旨在通过收入再分配或其他方式提高消费倾向的措施；因此，给定的就业水平需要较少的当前投资来支持它。

Now it is obvious that the actual rate of current investment will be pushed to the point where there is no longer any class of capital-asset of which the marginal efficiency exceeds the current rate of interest.

现在很明显，当前投资的实际利率将被推高到不再有任何类别的资本资产的边际效率超过当前利率的程度。

Thus whilst the multiplier is larger in a poor community, the effect on employment of fluctuations in investment will be much greater in a wealthy community, assuming that in the latter current investment represents a much larger proportion of current output.

因此，虽然贫困社区的乘数更大，但假设富裕社区的当前投资占当前产出的比例要大得多，投资波动对就业的影响将大得多。
