Suppose the consumption function is C = ''+ c (Y – T), where | is a parameter called autonomous consumption and c is the marginal propensity to consume. a. What happens to equilibrium income when the society becomes more thrifty, as represented by a decline in C? b. What happens to equilibrium saving? c. Why do you suppose this result is called the paradox of thrift?
