Inter-temporal and Inter-industry Effects of Population Ageing: A General Equilibrium Assessment for Canada

The objective of this paper is to examine the inter-industry and labour market occupational effects of future demographic changes, using a dynamic general equilibrium overlapping-generations model. The model is calibrated along a balanced-growth path, taking into account labour-augmenting (Harrod-neutral) technical progress. It also accounts for heterogeneity at the household level, using 25 occupations-specific earnings profiles. In addition to the impact of slower labour force growth, the model captures the shift in sectoral composition of final demand. The latter is due to different consumption preferences of older individuals. Moreover, a wage curve is introduced to explore the impact of population ageing on the unemployment rate. The simulation results indicate that the growth in real GDP per capita could decline by nearly one percentage point between 2006 and 2050. Besides, the production of services, in percent of total GDP, is projected to increase in the long-run, although the analysis shows more modest changes in production shares than in previous studies. The results also suggest that the equilibrium unemployment rate is likely to decline by more than 2 percentage points in the long run. The impact also varies quite significantly at the occupational level.
