Lump sum subsidy : one-time payment :: Per unit subsidy : ?

A lump sum subsidy is a one-time payment given to help someone financially, while a per unit subsidy is a payment made for each unit of a product or service sold or produced. This means that instead of receiving all the money at once, a person or business gets a specific amount of money for every unit they sell. For example, if a farmer receives a per unit subsidy of $2 for every bushel of corn they sell, they will get $2 each time they sell a bushel, rather than a single payment for all their corn at once. This approach encourages production because the more they produce, the more subsidy they receive. So, you can think of the relationship as lump sum subsidy being to one-time payment as per unit subsidy is to recurring payments based on production.
