Due to population aging, GDP growth per capita and GDP growth per working-age adult have become quite different among many advanced economies over the last several decades. Countries whose GDP growth per capita performance has been lackluster, like Japan, have done surprisingly well in terms of...

What sparked humanity's leap from stagnation to prosperity? What lies at the core of inequality among nations? Unified Growth Theory explores the evolution of societies over the entire course of human history. It uncovers the universal wheels of change that have governed the journey of humanity,...

In many developing countries today, the structural transformation is a shift of employment out of agriculture into the service sector. By contrast, industrial employment is mostly stagnant. Is the service sector an engine of growth and hence growth service led? Or is its expansion a mere...

New ideas are often combinations of existing goods or ideas, a point emphasized by Romer (1993) and Weitzman (1998). A separate literature highlights the links between exponential growth and Pareto distributions: Gabaix (1999) shows how exponential growth generates Pareto distributions, while...

This paper considers growth and fluctuations in a standard Overlapping Generations (OLG) model with rational expectations, with land (a non-produced asset), credit frictions, and endogenous growth. Under plausible conditions, there can be multiple momentary equilibria, with the multiplicity...

Technological advance is often embodied in capital inputs. This paper develops a model where capital innovations occur on two margins: (1) vertically, where a capital input becomes more productive at a given task; and (2) horizontally, where a capital input replaces labor at a given task. These...

We examine the dynamics of a country's growth, consumption, and sovereign debt, assuming that the government is myopic and wants to maximize short-term, self-interested spending. Surprisingly, government myopia can increase a country's access to external borrowing. In turn, access to borrowing...

This paper studies China's four-fold increase in per capita GDP relative to the U.S. between 1995 and 2019. First, we argue that China's growth pattern is very similar to that of several other East Asia economies that initially grew very quickly. Second, we show that a minimalist...

We augment Henderson, Storeygard, and Weil (2012)'s two-signal model of true income growth with a third signal to overcome its underidentification problem. The additional moment conditions from the third signal help fully identify all model parameters without ad-hoc calibrations of the GDP's...

Previous research finds correlation between sentiment and future economic growth, but disagrees on the channel that explains this result. In this paper, we shed new light on this issue by exploiting cross-country variation in sentiment and market efficiency. We find that sentiment shocks in G7...
