Answer:
speed money
Explanation:
"Speed money" refers to paying money in order to speed up the process. This is different from "bribery" in a sense that bribery is paying somebody the money to do something illegal.
In the case of Brain Wing Inc., the speed money is used in a "lawful way." It has legally won the bid to build airplanes for the host country, thus, using the speed money will just hasten its process so it can overcome the problem it faces in the less developed nation.
So, this explains the answer.
