CORE DEFINITION

A neoclassical economic growth model developed by Robert Solow, which posits that long-run economic growth is driven by technological progress, capital accumulation faces diminishing marginal returns, and the economy eventually reaches a steady-state equilibrium where the growth rate of output per capita equals the rate of technological progress.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Growth accounting. It provides a theoretical framework for understanding the sources and mechanisms of economic growth. In policy-making, it emphasizes the key role of technological progress in long-run growth, supporting policies that promote technological innovation and human capital investment to enhance the long-run growth rate of the economy.

Anchor fast decisions

Neoclassical framework: output is determined by capital, labor, and technology, with diminishing marginal returns to capital and labor. The economy tends toward a steady state, where the saving rate affects only the level of the steady state, not the long-run growth rate per capita; only technological progress (exogenous) generates sustained per capita growth. This is the structural basis for growth accounting.
