The global economy is likely to be stuck in the
 “twilight zone” of sluggish growth in 2013, Morgan Stanley has warned, 
but if policymakers fail to act, it could get a lot worse.
“More
 than ever, the economic outlook hinges upon the actions taken or not 
taken by governments and central banks,” Morgan Stanley said in a 
report.
Under the 
bank’s more gloomy scenario, the U.S. would go over the “fiscal cliff” 
leading to a contraction in U.S. GDP for the first three quarters of 
2013. In Europe, the bank’s pessimistic scenario assumes a failure of 
the European Central Bank (ECB) in cutting rates and a delay of its 
bond-buying program.
