The Japanese economy has seen a decline in the contribution of capital accumulation to economic growth since 2000. This column uses over 30 years of national productivity data to explore this trend. It finds that the fall in tangible capital accumulation has largely been offset by investment into intangible capital. However, the growth in tangible and intangible capital accumulation has been imbalanced, calling for support of both types of asset accumulation.

It is often argued that for poor countries, increases in agricultural productivity result in higher non-agricultural output, but the theory is ambiguous and the empirical evidence is limited. This column presents evidence from a natural experiment provided by China’s early 1980s agricultural reforms. Higher agricultural output induced by the reforms led to quantitatively important growth in non-agricultural output. This growth appears to be primarily due to rural savings increasing the supply of capital to the non-agricultural sector.

The extent to which lifetime incomes are determined by inherited wealth is a politically sensitive issue, but long-run evidence on this question is limited. This column presents evidence on Swedish inheritance flows since the early 19th century. Despite a long history of aristocracy, accumulated capital was small relative to income in pre-industrial Sweden. In more recent times, Sweden stands out as a country where the return of capital has not automatically translated into a return of inherited wealth.
