This paper reconsiders the two/one-class model of economic growth, att
ributable to Kaldor, Pasinetta, Meade, Samuelson, Modigliani, and Sate
, under the assumptions that part of corporate profits may not be dist
ributed as dividends. Using results of Baranzini (1998), the distribut
ion of property between the workers and capitalists is related to the
rates of return on capital, Implications of a positive retention ratio
are briefly considered.
