Capital in the Twenty-First Century

by Thomas Piketty

the return on capital, net of taxes (and losses), fell to 1–1.5 percent in the period 1913–1950, which was less than the rate of growth. This novel situation continued in the period 1950–2012 owing to the exceptionally high growth rate. Ultimately, we find that in the twentieth century, both fiscal and nonfiscal shocks created a situation in which, for the first time in history, the net return on capital was less than the growth rate. A concatenation of circumstances (wartime destruction, progressive tax policies made possible by the shocks of 1914–1945, and exceptional growth during the three decades following the end of World War II) thus created a historically unprecedented situation, which lasted for nearly a century. All signs are, however, that it is about to end.
