Stuck in the middle' is never a good ending to a story. Especially
 when it comes to economics, we like clear stories of good and evil. 
"The  Soviet Union
 collapsed because it banned private enterprise", or "the US is the 
world's biggest economy, because it encourages innovation", are the 
kinds of stories we like.  Less compelling is an  
economy
 which grew strongly, then stopped growing, well before it became rich. A
 country which just runs out of steam altogether somehow seems less 
interesting. 
 Yet that's the real danger that the  
International Monetary Fund
 (IMF) points to, in its regional economic outlook for Asia which it 
released last week. It pointed out that the fast-growing economies of 
Asia — from China to India to  
Vietnam to Malaysia — faced the risk of falling into a 'middle-income trap'. 
 Which means that average incomes in these countries, which till now had
 been growing rapidly, will stop growing beyond a point — a point that 
is well short of incomes in the developed West. Effectively these 
countries could become 'middle class', and stay that way.  
Falling into the Trap 
 The idea of a 'middle-income trap' is not new. Before Asia, the 
countries believed to have suffered most from the middle-income trap 
phenomenon were the hitherto fast-growing economies of Latin America, 
during their famous 'lost decade' of the 1980s, when growth stalled, 
industrial production stagnated and  
unemployment and  
inflation both remained high.
   
  "The lesson from what happened in  Latin America
 is that you cannot get complacent about growth," says Shekhar Aiyar, a 
co-author of an IMF paper ("Growth Slowdowns and the Middle-Income 
Trap") on which the IMF outlook was based. "Just because you are seeing 
fast growth doesn't mean it will last." The bottomline: just because you
 made the transition from a low-income economy to a middle-income one, 
don't expect to easily clear the next hurdle, from a middle- to 
high-income economy.
   Growth Slowdowns 
 Indeed, as the research shows, once a country reaches the middle-income
 stage (defined as anything between $2,000 and $15,000 per annum per 
person in what are called 'international dollars' which enable 
cross-country comparisons), the stakes and risks actually go up. 
Middleincome economies are far more prone to slowdowns in growth than 
either low- or high-income economies. The effects of a middle-income 
trap were there for all to see after the Asian crisis of 1997. 
 
The IMF report points out that while the Asian Tiger economies - Taiwan,
 Singapore, South Korea and Hong Kong — reached high-income levels, "the
 experience of several other Asian middle-income economies (MIEs) has 
been more mixed, reflecting in part the transitory but large effect on 
living standards of the Asian crisis of the late 1990s. 
 
Malaysia has been more success- ful than Indonesia, with Thailand 
falling in between, but in all three cases convergence to living 
standards in advanced economies stalled for a decade after the Asian 
crisis, regaining momentum only in recent years." 
 But what 
causes such growth slowdowns and middle-income traps? The IMF paper and 
report identify a number of causes — none of which are surprising — from
 infrastructure to weak institutions, to less-than-favourable 
macroeconomic conditions. 
 But the broad, overall cause, says 
the research, is a collapse in the growth of productivity — the ability 
for a given amount of labour and capital to produce ever-increasing 
amounts of output. Such productivity is driven by, along with 
technological innovations, a range of other factors from  
higher education and skill levels (more skilled workers are more productive), and also the state of institutions and infrastructure.
