1.2. Activities Exercise No. 1 (60 points) Suppose an economy for which we know that there is a fixed exchange rate of 1500 diner/$. Explain and graph (IS/LM and money market) what effect it would have on the interest rate if the current exchange rate is 800 diner/$. Indicators / Levels of achievement Achieved Moderately achieved Not achieved Explanation Explain correctly Considering the relationship cause effect the model IS/LM and market monetary Taking into account the cause effect relationship (30 points) Explain correctly Considering the relationship the IS/LM model causes an effect Taking into account the cause effect relationship (15 points) Does not explain correctly and does not take into account the cause effect relationship (0 points) Chart Changes are identified produced in IS/LM and money market. (30 points) Change is identified produced in IS/LM. (15 points) No change is identified produced in IS/LM neither in market exchange rate.
