  2. Fig. 11.01 Equilibrio generale Figure 11.1

  3. Fig. 11.01 IS Equilibrium in the goods market Changes in output will occur when we are not on the IS curve (as response to shortage to the left of IS and surplus to the right). Interest rate Output Figure 11.1

  4. Fig. 11.01 LM Equilibrium in the money market Changes in the interest rate will occur when we are not on the LM curve. Below LM there is an excess demand for money (bonds chase money). Above the LM there is an excess supply of money (money chases bonds). Interest rate Output Figure 11.1

  5. Fig. 11.01 LM IS Y1 General equilibrium A Interest rate Output Figure 11.1
