3 Copyright © 2002 Pearson Education, Inc. Slide 24-3 A Model for Goods and Assets Markets: Assumptions General equilibrium occurs when all the markets are in simultaneous equilibrium. The goods market includes trade in all goods and services that the economy produces. The money market includes trade in all assets used as the medium of exchange. Nonmoney asset market includes trades of nonmonetary assets that are stores of value.

5 Copyright © 2002 Pearson Education, Inc. Slide 24-5 Determinants of National Saving National saving increases when current income or current output rise. A rise in expected future income causes national saving to fall. National saving increases with the interest rate, although the effect probably isn’t large. Holding current output constant, an increase in government purchases reduces saving.

10 Copyright © 2002 Pearson Education, Inc. Slide 24-10 Determining Output: The Full Employment Line Full-employment output is the production level when all production factors are used. On the IS diagram, full employment is represented as a vertical line at Y *.

12 Copyright © 2002 Pearson Education, Inc. Slide 24-12 The LM Curve In the asset market: M d + N d = M s + N s. Equilibrium in the nonmoney asset market implies equilibriumin the money market. The LM curve is the set of combinations of current output and the real interest rate for which the money market is in equilibrium.

16 Copyright © 2002 Pearson Education, Inc. Slide 24-16 The IS-LM-FE Model The financial and goods market are both in equilibrium when IS, FE, and LM intersect. The economy will restore equilibrium if the IS curve, the LM curve, or the FE line shifts. The neutrality of money implies that a one- time change in the nominal money supply affects only nominal variables.
