Answer:
when valuing companies with temporarily high growth rates.
Explanation:
Discounted dividend models are methods to assess a company's share price based on the dividends that company will distribute in the future. Also known by its name in English dividend discount model (DDM).
These models are based on the theory that the price of a share must be equal to the price of the dividends that the company will deliver, discounted at its net present value.
If the price of the share in the market is lower than the result obtained by the discounted dividend model, the share is undervalued and therefore it is advisable to buy. If, on the contrary, the market price is higher than the model, it is understood that the share price is too high.
Multistage dividend growth models
It is very difficult for a company to experience the same growth every year as the Gordon model assumes, so multistage models assume different growths for each period.
The most common is to use two or three stage growths, where at first the growths are higher but then tend to stabilize at a smaller constant growth. As for example in early stage companies.
A is the answer
Because the rest do not make sense
Inventions usually start out with a small idea. Just like the story for honey bunches of oats, his daughter smiled because she knew he was up to something (and they never ever knew they would become very famous with their cereal).
Since many people are dying from diseases, you could make an invention that rates how close you are to get that disease. It could warn you on when you might get it (for example, it tells you that a person behind you has a flu, so make sure to stay away from that person.).
It would be called 'The-World-Is-Healthy' because it would decrease the spread of disease.
That would change the world.
