Since fall of 2004, increasing oil prices [over $70 per barrel in the Spring of 2006] have frequently ended stock market rallies and led to refuse in all major stock indexes.
Make an AS/AD diagram which shows the effect on the United States macro-economy of oil at $70+/barrel versus oil at $40/barrel.
Label your diagram clearly and explain how higher oil prices impact either AS, AD, or both.
Finally, describe why rising oil prices have negatively impacted United States equity markets.
