1. Solow Model Assumptions and Purpose

Key Concepts & Definitions

  • Solow model: Model explaining the proximate causes and mechanics of long-run economic growth and cross-country income differences.

★ Must-know

  • The main assumptions are: one good and a closed economy, no government sector, production using capital K, labor L, and knowledge or technology A, full employment of inputs, exogenous constant growth of labor, technology, saving, and depreciation, identical technology across firms, publicly available, non-excludable, and non-rival technology

Further detail

  • The Solow model studies long-run growth over years rather than short-run movements over months, beginning from a low capital level and converging toward a steady state through capital accumulation.
