Questions and Answers

What does the discounting formula W β Ulct imply when beta is between 0 and 1?

The level of social welfare is always finite.

$1000 in 100 years is worth $250 today at a 1% discount rate. (correct)

$1000 in 100 years is worth $10 today at a 4% discount rate. (correct)

There is no difference between policies A and B.

If beta equals 1, the level of social welfare is considered to be infinite.

True

What is the implication of policy A compared to policy B in terms of consumption over time?
