Sharing contracts in franchising the marginal benefit of the effort

Assuming initially that the required reserve ratio = 10%, the currency-deposit ratio = 40%, and the excess reserve ratio = 0, an decrease in the currency-deposit ratio to 30% causes the M1 money multiplier to ________, everything else held constant

A) increase from 2.8 to 3.25 B) decrease from 3.25 to 2.8 C) increase from 2.8 to 3.5 D) decrease from 3.5 to 2.8

C) this suggests the presence of a deterministic trend in addition to a stochastic trend. D) forecasting, but not inference, is unaffected, if the break occurs during the first half of the sample period.
