This paper investigates the impact of the desire to keep up with the Joneses (KUJ) on economic growth and optimal tax policy in a continuous time overlapping generations model with AK technology and gradual retirement. Due to the desire to KUJ, the propensity to consume out of total wealth rises...

This paper investigates the impact of externalities on economic growth in an AK model. In contrast to the existing literature, the paper considers finitely-lived agents along the continuous time, overlapping generations literature. A series of new results, not holding for infinitely-lived agent...

Assuming a production process with returns to scale that vary with the intensity it is operated at, an AK-model of endogenous growth with constant returns to scale in production is shown to arise due to replication driven by profit-maximization. If replication occurs at the efficiency-maximizing...
