ut economic growth has been disappointing for many years. Only a mild recovery is in store after the setback in 2005, when GDP rose by little more than 1%. Indeed, the economy is stuck in “a low-growth trap� says the OECD, chiefly because of weak gains in efficiency. The main reasons why productivity growth has been so sluggish are a lack of competition fuel dispenser in sheltered product markets together with a poorly performing public sector. Although Switzerland s record of innovation is among the best, it is weaker in smaller firms and is not being helped by low attendance at university. The OECD recommends reforms to reduce trade protection and to liberalise the postal services and electricity and gas industries. It also calls for more competition in the health system to promote greater efficiency. fuel dispenser © 2006 . Money and interest rates Jan 19th 2006 From The Economist print edition © 2006 . The Economist commodity price index Jan 19th 2006 From The Economist print edition © 2006 . Stockmarkets Jan 19th 2006 From The Economist print edition © 2006 . Trade, exchange rates and budgets Jan 19th 2006 From The Economist print edition © 2006 . Government bonds Jan 19th 2006 From The Economist print edition © 2006 . Overview Jan 19th 2006 From The Economist print edition China and South Korea hold more foreign-exchange reserves than ever before.
