Long-term labour productivity and GDP projections for the EU25 Member States : a production function framework

This paper presents the results of long run labour productivity and GDP growth rate projections (until 2050) for each of the 25 EU Member States and provides a detailed overview of the forecast methodology used. These projections were undertaken in order to provide an internationally comparable macroeconomic framework against which to assess the potential economic and fiscal effects of ageing populations. The projections presented in this paper, using a common production function methodology for all 25 countries, show the GDP growth rate effects of an assumptions-driven extrapolation of recent trends in employment and labour productivity. These base case projections reflect the working assumption of “no policy change”.Various sensitivity tests are carried out to check the GDP per capita impact of some factors which have been excluded from the baseline scenario for reasons of simplicity or because of a lack of consensus in the academic literature. Some of the interesting conclusions that emerge from these sensitivity tests include : • Firstly, the GDP per capita impact of changes in the participation rate assumption used in the projections is much greater than for assumed changes in the share of part-time employment (i.e. in average hours worked per worker). • Secondly, the negative effect of a change in the age-structure of the population is fairly limited, although it is accepted that the labour productivity of an individual is likely to decline after the age of 55. A very strong fall in the productivity of older workers compared with that of prime-age workers would be required to significantly depress total labour productivity. Such an outcome, on the basis of current evidence, appears rather unlikely. • Thirdly, changing the TFP growth rate targets (e.g. use of the 1990’s average instead of the long-term 1970-2004 average) could strongly affect the projections. • Finally, an assumption of productivity convergence in levels substantially alters the projections for most EU10 countries but leaves the EU15 almost unchanged.
