Problem #1: Aggregate Demand Saving the Jupiter (Continued from last time) Careful as he is, Michael was kidnapped (We’ve said: Use your imagination!). There is a reason why Michael is kidnapped! The economy in Jupiter is experiencing a severe recession. Though technically advanced, they don’t have any good economist. And there in this blue planet they found Michael and the 100 dollar bill in his pocket… The economy in the Jupiter is described by (take the planet in its entirety as a closed economy): Y = C + I + G, C = 2,000 + 0.5(Y-T), I = 10,000 – 40,000r, G = 2,000, T=0.2Y And the supply and demand in the money market (sorry we don’t know the name of their currency yet…) M s =1,000 M d = 5,000 – 20,000r Where r is the interest rate written as a decimal (e.g., if the interest rate r equals 10% then it would appear in the equation as 0.1) and the required reserve ratio for demand deposit is 20%.
