Most of the world is now at the point where the support ratio is becoming adverse, and the growth of the global workforce is slowing. This column argues that these changes will have profound and negative effects on economic growth. This implies that negative real interest rates are not the new normal, but rather an extreme artefact of a series of trends, several of which are coming to an end. By 2025, real interest rates should have returned to their historical equilibrium value of around 2.5–3%.

The CEPR Press eBook on secular stagnation has been viewed over 80,000 times since it was published on 15 August 2014. The PDF remains freely downloadable, but as the European debate on secular stagnation is moving into policy circles, we decided to also make it a Kindle book. This is available from Amazon; all proceeds will help defray VoxEU expenses.

Thomas Piketty’s new book has been widely praised for its empirical contribution, but his prediction of rising inequality rests on economic theory. This column argues that Piketty’s pessimistic forecast is based on an extreme – and unrealistic – assumption about households’ saving behaviour. According to standard theory, the wealth–income ratio would increase only modestly as growth falls, so declining growth would not be a powerful force for generating high inequality.

Household savings in China are high by international standards, and the young save as much or more than the middle-aged – a fact at odds with the standard life-cycle savings model. This column argues that neither old-age support by the middle-aged nor the one-child policy can satisfactorily explain this phenomenon. Rather, currently high housing costs and the prevalence of inter-generational shared housing are key reasons for the higher savings rates of the urban young in China.

Corporate saving has sharply increased over the last two decades, but there has been relatively little research on its determinants. This column presents recent work that estimates Asian firms’ cash flow sensitivity of cash. The impact of cash flow on the increase in firms’ cash holdings is positive and statistically significant, and larger and more highly significant for smaller firms. Since smaller firms are more likely to be financially constrained, these results suggest that Asian firms – especially smaller ones – save more when their cash flow increases in order to finance future investments

Since China is growing rapidly, one might expect Chinese households to borrow against their future income. In fact, Chinese households save 30.5% of their income – compared to about 5% in OECD countries. This column discusses recent research linking the Chinese saving puzzle to China’s one-child policy. The savings rate of households with twins is about 6–7 percentage points lower than that of households with an only child. Demographic factors can explain an estimated 35–45% of the 20 percentage-point rise in China’s household saving rate between 1983 and 2011.

Latin America and the Caribbean have less infrastructure than the rest of the world. What they have is also of much poorer quality. This column argues that to reap the rewards of good infrastructure, Latin American and Caribbean countries must increase both investment and saving over the long-term by creating institutional capacity, strengthening the rule of law, and building stable macroeconomic-policy frameworks. It won’t be easy.

Policymakers in many commodity-exporting countries confront the question of how much to consume, save, and invest out of revenues from commodity exports. This column says policy should focus on improving productivity in the tradeable sector and reducing volatility through diversifying this sector. This would lower precautionary saving needs, increase investment, raise consumption, and improve welfare.

Uncertainty rose sharply during the Great Recession, as did saving rates. This column shows that these two developments were related. Using a panel of OECD countries, it estimates that at least two-fifths of the increase in households’ saving rates between 2007 and 2009 was due to increased uncertainty about labour-income prospects. It adds that restoring higher levels of consumption and aggregate demand will require employment-friendly social insurance and reduced policy-induced uncertainty.
