- 2. SHORT 1-2 Quarters MEDIUM 2-3 Years LONG 3-4+ Decades Accuracy Policy relevance/ Interest 2 The merits of forecasting at different horizons Good & Improving ? For Nerds! Poor & Little Improvement Usually Miss Downturns Fiscal & mopo credibility Quantifying uncertainty … tricky Planning rather than the Plan Timing of cycle less important Natural horizon: • Structural reforms • Mega-trends like ageing • Debt sustainability
- 3. • All OECD + non-OECD G20 countries • Core is production function for potential output • Linked to short-term Economic Outlook projections • Saving & Investment equilibrated through R Long-term scenarios model: key features 3
- 5. Fiscal block: spending pressures • Health spending per capita projections depend on – Growth in real GDP per capita – Change in the share of population aged 65+ – Baumol effect: 1.3% per year • Pension expenditure from EC Ageing Report and S&P’s projections • Other primary expditure constant on real per capita basis. – Additional channel demographics public finances – Structural reforms that boost employment rate fiscal dividends. 5

- 9. Demographic change weighs on growth in OECD living standards The positive contribution from a rising employment rate declines and the contribution of the working-age population share turns negative -0.5 0.0 0.5 1.0 1.5 2.0 -0.5 0.0 0.5 1.0 1.5 2.0 2005 2010 2015 2020 2025 2030 2035 2040 2045 2050 2055 2060 Trend real GDP per capita growth in the OECD, % 9
- 10. Living standards converge slowly • GDP per capita advances in all countries and gradually converges toward those of the most advanced countries, but to varying degrees. • Living standards in high-growth emerging market and Eastern European converge most, driven by catch-up in trend labour efficiency, • But GDP per capita in the BRIICS and some low-income OECD countries remains below half that of United States in 2060. 0 40 80 120 160 200 0 40 80 120 160 200 IND IDN ZAF COL BRA CRI CHN MEX ARG CHL RUS GRC LVA TUR HUN POL PRT EST LTU SVK SVN CZE ISR ESP ITA NZL KOR FRA JPN GBR FIN BEL CAN AUS DEU AUT DNK SWE ISL NLD CHE NOR IRL LUX 2018 2060 C.
