Difference Between Solow-Swan and Endogenous Growth Theories

In the realm of economic growth theories, two prominent models are the Solow-Swan growth model and the endogenous growth model. The Solow-Swan model emphasizes the role of capital accumulation, labor or workforce, and technological advancement, attributing long-term economic growth primarily to these factors. Conversely, the endogenous growth model posits that economic growth is primarily generated from within the economy, mainly through factors such as human capital, innovation, and knowledge spillovers, which can lead to increasing returns to scale.
