Saving and Investment in the Twenty-First Century cover

The economy of the 21st century in the OECD countries and in China, is characterized by a new phenomenon: the structural surplus of private savings in relation to private investment. This is true even in a situation of prosperity and very low interest rates. On the one hand, this excess saving is due to people's increasing inclination to save in light of rising life expectancy, driven by the desire to have sufficient assets in old age. On the other hand, the demand for capital is not increasing to the same extent, so that investment is not keeping pace with the rising desire to save. The resulting gap between the private desire for wealth and private investment can only be closed by increasing public debt. 

This open access book offers a new, capital-theoretical perspective on the macroeconomic relationship between desired wealth and investment, and it presents new empirical data on private wealth and its composition in the OECD plus China area. The authors arguethat a free economic and social order can only be stabilized if the wealth aspirations of individuals are met under conditions of price stability. This is not possible without substantial net public debt. A new way of thinking about the economy as a whole is required. By way of an in-depth theoretical and empirical analysis, the book demonstrates this new way of thinking and describes the current challenges facing economic policy. It will appeal to economists and students of economics who are interested in macroeconomic theory and its economic policy implications.


An impressive, and convincing theoretical dive into the fundamentals behind secular stagnation, with very strong implications for actual debt policy. Public debt may be needed to improve welfare.

Saving and Investment in the Twenty-First Century gives a wholly new perspective on macroeconomics. (...) Weiz­säcker and Krämer describe a simple, practical solution to the underemployment that has plagued Southern Europe for more than a decade.
