The Solow Growth Model is described in detail at a level suitable for undergraduates in Charles I. Jones, Economic Growth, Second Edition, W.W. Norton and Company, 2002.

Production is given by the production function Y = K^{a}(AL)^{1-a},
where Y is output, K is capital, L is labor, and A is a labor-augmenting
technology factor. The capital stock increases in a given period by the
amount sY - dK, where s is the savings rate and d is the depreciation rate.
The labor force grows at rate n, and the technology factor A grows at rate g.
