The national income identity is given by n=q+n+m+ardm [H where l" is real actual output. (2': is consumption. 1; is investment. G, is government spending, EX, is expons. and 1M; is imports (all in period t}. Assume that the \"demand\" variables are given by: q=g [a 0:1,? 5, +91"; [31 H%=% m 1mk=mm [ W=mRm @ Where is . g , Eu , rm . ; , g and E are given positive parameters. Moreover, E represents potential output}; is short-run output, RI is the real interest rate, and F is the marginal product of capital or just the long run interest rate. I of 5) Combine equations (2)46} with (1} to obtain the [5 curve. This curve should have short run output on the left-hand side and the real interest rate on the right~hand side. Recall from the lectures '"VP: 1"; difference of actual output from the potential. (10 points) that we dened short run output as ll} = . In other words. short run output is the percentage
