Present value models follow a fundamental tenet of economics that states that individuals invest:

选项：

A.to defer consumption. B.based on the law of one price. C.for the expected future benefits.

解释：

Solution

1. Incorrect because, while people must defer consumption to invest, their motivation for doing so is that they expect a rate of return over the investment period that will create future benefits.

2. Incorrect because, while the law of one price is the economic rationale underlying the method of comparables for judging asset valuation, it is not the economic reasoning that explains why people invest.

3. Correct. Present value models follow a fundamental tenet of economics stating that individuals defer consumption—that is, they invest—for the future benefits expected.
