The Japanese economy has experienced a prolonged slowdown in growth and persistent declines in the real interest rate, while at the same time the country’s labour force has been rapidly ageing. This column explores a novel causal link between the ageing labour force and the low-frequency declining trend in the real interest rate since the 1970s, and suggests that the ageing of the labour force accounts for 40% or more of the declines in the real interest rate observed between the 1980s and 2000s in Japan.

Population ageing reduces labour supply and burdens pension systems. At the same time, delaying the statutory retirement age may have an impact on firms’ productivity and risks crowding out younger workers. This column exploits an unexpected pension reform in Italy in 2012 which sharply increased the full retirement age for workers aged 55 or above to show that such concerns may not be warranted. A rise in employment of older workers led to an increase in value added while holding labour costs constant. Employment in other age classes also increased. This suggests older workers are valuable to employers and that pension reforms postponing retirement can remove a constraint rather than placing a burden on firms.

This columns asks what the people think, focusing on a survey from the Netherlands. It turns out that most people are in favour of global population decline, but “not in my backyard”.
