OECD says lacklustre progress in productivity threatens Swiss prosperity. The OECD (Organisation for Economic Cooperation and Development) has just published a final version of its economic study of Switzerland, which analyses the situation in 2005. Although Switzerland is still a prosperous country its per capital growth is low and considerably below the OECE average over the last few years, mainly because of the low level in productivity. Without any significant increase in productivity, trend output growth will further decrease to as little as 0.5% by 2020 due to the ageing population. The OECD also states that the dynamics of social spending are not sustainable in the long term. Switzerland is now faced with the double challenge of raising growth performance and restoring better control over public spending.
