When Mother Theresa accepted the Nobel prize for Peace in 1979 and decided to use the $190,000 award to construct a leprosarium, was she acting in her own interest? Was she behaving selfishly? Was she following economic principles? Explain.

Most people who give money away act on a combination of altruism, self-interest, and economic principles.

She obviously really believed in funding a leprosarium and was behaving altruistically in donating her prize.

She also probably felt good about donating her award to it and so had a selfish interest in this donation.

I have no idea about her tax structure -- but it's likely that she derived some economic benefit from this donation.
