Could the bad old days of economic decline be about to return Since OPEC agreed to supply-cuts in March, the price of crude oil has jumped to almost $26 a barrel, up from less than $10 last December. This near tripling of oil prices calls up scary memories of the 1973 oil shock, when prices quadrupled, and 1979—80, when they also almost tripled. Both previous shocks resulted in double-digit inflation and global economic decline. So where are the headlines warning of gloom and doom this time

A. global inflation
B. reduction in supply
C. fast growth in economy
D. Iraq’s suspension of exports
