To rationalize a substantial income share of labor despite progressive task automation over the centuries, we present a simple model in which demand moves along a vertically differentiated production structure toward goods of increasing sophistication. Automation of more sophisticated goods...

A new macroeconomic model is presented, which makes it possible to take a fresh look both at the long-term equilibrium growth process and at short-term deviations from it. Its key hypothesis is investment-to-profits equality. This hypothesis has classical roots and corresponds to the Ricardian...

Uzawa's steady-state growth theorem (Uzawa (1961)) is generalized to a neoclassical economy that uses current output, e. g., to create technical progress or to manufacture intermediates. The difference between aggregate final-good production and these resources is referred to as net output. The...

The Uzawa (1961) theorem applied to finance and growth suggests that a long-run positive correlation between financial efficiency and depth is only present when variations in the extent of access to financial services are considered. Improvements in financial efficiency can lead to new capital...
