This paper provides a critique of the ?unemployment invariance hypothesis,? according to which the behavior of the labor market ensures that the long-run unemployment rate is independent of the size of the capital stock, productivity, and the labor force. Using Solow growth and endogenous growth...

This study provides a uni ed growth theory to correctly predict the initially negative and subsequently positive relationship between child mortality and net reproduction observed in industrialized countries over the course of their demographic transitions. The model captures the intricate...

We present a tractable model for analyzing the relationship between economic growth and the intensive and extensive margins of technology adoption. The “extensive" margin refers to the timing of a country's adoption of a new technology; the “intensive" margin refers to how many units are...

A core mechanism of unified growth theory is that accelerating technological progress induces mass education and, in interaction with child quantity-quality substitution, a decline in fertility. Using unique new data for 21 OECD countries over the period 1750-2000, we test, for the first time,...

We introduce a growth model of technology diffusion and endogenous Total Factor Productivity (TFP) levels both at the sector and aggregate level. At the aggregate, the model behaves as the Neoclassical growth model. Our goal is for this model to bridge the gap between the theoretical and...
