The 19th century economist, Thomas Robert Malthus, hypothesized that the long-run supply of labor is completely elastic at a fixed wage-income level because population growth tends to outstrip real output growth. Dynamic equilibrium with constant income and population is achieved through...

This paper sketches a theory of the secular decline in morbidity and mortality that takes account of changes in human physiology since 1700. The synergism between technological and physiological improvements has produced a form of human evolution, much more rapid than natural selection, which is...

This paper examines the central hypothesis of the influential Malthusian theory, according to which improvements in the technological environment during the pre-industrial era had generated only temporary gains in income per capita, eventually leading to a larger, but not significantly richer,...

A recent endogenous growth literature has focused on the transition from a Malthusian world where real wages were linked to factor endowments, to one where modern growth has broken that link. In this paper we present evidence on another, related phenomenon: the dramatic reversal in...

This paper argues that the secular decline in mortality, which began during the eighteenth century, is still in progress and will probably continue for another century or more. The evolutionary perspective presented in this paper focuses not only on the environment, which from the standpoint of...

This paper argues that openness to new, unconventional and disruptive ideas has a first-order impact on creative innovations-innovations that break new ground in terms of knowledge creation. After presenting a motivating model focusing on the choice between incremental and radical innovation,...

Using international data starting in 1957, we construct a sample of cases where fast-growing economies slow down. The evidence suggests that rapidly growing economies slow down significantly, in the sense that the growth rate downshifts by at least 2 percentage points, when their per capita...

During the past two decades, there has been a dramatic change in IPO activity around the world. Though vibrant IPO activity, attributed to better institutions and governance, used to be a strength of the U.S., it no longer is. IPO activity in the U.S. has fallen compared to the rest of the world...

This paper presents evidence that public debts in the advanced economies have surged in recent years to levels not recorded since the end of World War II, surpassing the heights reached during the First World War and the Great Depression. At the same time, private debt levels, particularly those...

This paper documents industrial output and labor productivity growth around the poor periphery 1870-1975 (Latin America, the European periphery, the Middle East, South Asia, Southeast Asia and East Asia). Intensive and extensive industrial growth accelerated there over this critical century. The...
