Change in equilibriums Apparently, change in policy variables or y parameter can change the equilibrium Consider a change in G, denoted as AG. Is e the change in GDP, denote as AY, will satisfy 2 △Y= △G 1-c(1-1) as we have described in chapter 32 2Change in Equilibrium • Apparently, change in policy variables or parameter can change the equilibrium • Consider a change in G, denoted as G.
