10. Suppose that the government increases expenditures by $150 billion while increasing taxes by $150 billion. Suppose that the MPC is .80 and that there are no crowding out or accelerator effects. What is the combined effects of these changes? Why is the combined change not equal to zero?
The increase of $150 billion in government spending changes the aggregate demand by 5 times to $750 billion. The tax increase decreases overall income by $150 billion which leads to an initial decrease in consumption by $120 billion due to the MPC of .80. This leads to a net change of $150 billion due to the multiplier effect of $600 billion ($120 x 6 = $600). The changes don't cancel each other out, because a tax increase decreases consumption by less than the tax increase
19. Some economists argue suddenly reducing money supply growth is a costly way to reduce inflation and that it may not work. For example, if a government cuts money growth but makes no real fiscal reforms, people will expect the government will eventually need to expand the money supply to pay for its expenditures. This, the promise to fight inflation will not be credible. Explain why credibility is important to a reduction in the inflation rate.
When the government proposes this idea, the people start to believe that they will honor this promise to reduce inflation and inflation expectations fall along with it. This change shifts the short-run Phillips curve left so that the actually unemployment and inflation rates will be lower. If the government reduces money supply growth and at the same time people reduce their inflation expectations, unemployment will rise less than if people retained their previous inflation expectations.
20. Explain how an increase in the price level changes interest rates. How does this change in interest rates lead to changes in investment and net exports?
When the price level increases, the purchasing power of money that is held by citizens declines. This causes money holders to feel poorer or less wealthy which causes them to lend less money to different outlets. The lowered lending makes the interest rate go up and this discourages spending. The aggregate quantity of goods and services decreases with this trend. As the interest rate increases, the supply of money in the market for currency exchange drops and people buy less foreign assets. This causes the dollar to appreciate which decreases net exports.
12. Suppose the Central Bank of Namdia Purchases 25 million días of Namdian Treasury Bonds from banks. Suppose also that both the reserve requirement and the percentage of deposits held as excess reserves stay the same. By how much would the money supply of Namdia change?
a. 200 million dias
5. Suppose points F and G on the right-hand graph represent two possible outcomes for an imaginary economy in the year 2012, and those two points correspond to points B and C, respectively. on the left-hand graph. Also suppose we know that the price index equaled 120 in 2011. The the number 115 and 130 on the vertical axis on the left-hand graph would have to be replaced by
b. 138 and 156, respectively
7. Suppose that in some tax year you earned a nominal interest rate of 6 percent. During the time you held these funds inflation was 1 percent. You compute that you made a real after-tax interest rate of 3 percent. What was your tax rate?
b. 33.3 percent

6. Suppose the price index was 100 in 2014, 109 in 2015, and the inflation rate was lower between 2015 and 2016 than it was between 2014 and 2015. The means that
