(exercise 15.5) consider a variation of the television station broadcast game of exercise 4 in chapter 7. suppose the stations interact sequentially. first, mbc chooses between 6: 00 and 7: 00. then, after observing mbc’s choice, rbc decides between 6: 00 and 7: 00. finally, after observing the behavior of both mbc and rbc, cbc chooses either 6: 00 or 7: 00. payoffs are as given before. draw the extensive form of this sequential game and compute the subgame perfect equilibrium. is the outcome different from that in the simultaneous-play game? explain.

What could explain why a decrease in taxes could lead to a less-than-proportionate increase in output? a. as a result of diminishing returns to current consumption, consumers may choose to spread the extra spending over the long term rather than consuming the proceeds of a tax cut all at once. b. consumers may choose to save much of the tax cut in anticipation of having to pay higher taxes in the future. c. a decrease in taxes will necessitate lower government outlays, thus largely offsetting the higher consumption expenditures of households. d. all of the above. e. a and b only.
