According to The Global Competitiveness Report 2015-2016, the failure, particularly by emerging markets, to improve competitiveness since the recession suggests future shocks to global economy could have deep and protracted consequences.
"However, there are bright spots: India ends five years of decline with a spectacular 16-place jump to 55th. South Africa re-enters the top 50, progressing seven places to 49th," WEF said.
Elsewhere, macroeconomic instability and loss of trust in public institutions dragged down Turkey (51st), as well as Brazil (75th), which posts one of the largest falls. While Russia was ranked 45th in the index down from 53 last year.
"This dramatic reversal is largely attributable to the momentum initiated by the election of Narendra Modi, whose pro-business, pro-growth, and anti-corruption stance has improved the business community's sentiment toward the government," WEF said.

WEF noted "the fact that most notable improvements are in basic drivers of competitiveness bodes well for the future, especially the development of the manufacturing sector. But other areas also deserve attention, including technological readiness: India remains one of the least digitally connected countries in the world (120th, up one)"
Meanwhile, among the South Asian Association for Regional Cooperation (SAARC) countries, India led the way at 55th, followed by Sri Lanka (68th, up five). Nepal (100th, up two), Bhutan (105th, down two), Bangladesh (107th, up two), and Pakistan (126th, up three) all rank 100th or below.
