Recall that ˙ k = sBk - ( x + n + δ ) k ˙ k k = sB - ( x + n + δ ) g Y/L = g y + g A = sB - ( x + n + δ ) + x = sB - n - δ Which clearly does not depend on the growth rate of technological progress at all! Recognizing that the savings rate will also aﬀect the growth rate of Y/L is also suﬃcient. A2 : False. MV = PY so if M goes up that means that PY must go up. This means
