2. At the command prompt, type cd samples and press Enter. At the command prompt, type ls -R and press Enter. Note the two empty directories todelete and undermysamples.

3. At the command prompt, type rmdir undermysamples todelete and press Enter. Did the command work? Why? Next, type ls –F at the command prompt and press Enter. Were both directories deleted successfully?

4. At the command prompt, type rm sample1* and press Enter. What message is displayed? Answer n to all three questions.

5. At the command prompt, type rm –f sample1* and press Enter. Why were you not prompted to continue? Next, type ls –F at the command prompt and press Enter. Were all three files deleted successfully?

6. At the command prompt, type cd .. and press Enter. Next, type rmdir samples at the command prompt and press Enter. What error message do you receive and why?

1. In our model from chapter 4, the supply of bonds to domestic and private sectors equals the demand for bonds, i.e.
   1. Plot this graphic, label the axis and explain why the supply of bonds to domestic and private sectors is a vertical line.
   2. Use this graphic to show and explain what happens to the interest rate if the central bank decides to reduce their holding of Domestic government Bonds .
   3. Can you say what happens, under this scenario, to the demand for foreign bonds, i.e. the demand for bonds issued by foreign governments.
   4. Show in the Monetary market the effect of the decision the central bank took. Explain in words why the curve(s) shift.

3. Consider the case of a gold-standard economy.
4. What effect would you expect an increase in the price of gold to have on the level of domestic real GDP, and why?
5. What effect would you expect the change in real GDP to have on net exports?
6. What is the net effect of the increase in the price of gold and the change in real GDP on net exports, and why?

Make up a case where molecular biology can be used to prosecute a suspect accused of growing and selling marijuana. How would molecular biology be used? What evidence or results would be needed to convict the suspect?

Firms make more investment in new artificial intelligence program that develops high caliber robots which can handle large amount of data and then deliver instructions to workers.

1. Explain how the investment plan affect the IS, LM and Ad curves?
2. Suppose the workers’ productivities and worker’s expected incomes are unaffected. How will this affect the AS curve with and without this assumption?
3. For simplicity, we keep the assumption in part (b). Use your answers in (a) and (b) to discuss the real interest rate, employment, real wages, nominal wages, consumption, investment, and the price level.
4. According to the misperceptions theory, modify the above AS-AD graph to show the short-term equilibrium.
