b. Now show the immediate effect of the supply shock in your diagram.

c. Suppose wages and prices in this economy adjust instantly to shocks. Describe what happens to unemployment in this economy. Explain.

d. If wages and prices adjust only slowly to shocks, what happens to unemployment? Explain.
