In this paper we derive an analytical expression for the regional neoclassi
cal economic base marginal employment multiplier. The model that we adopt i
s a variant of the 1-2-3 general equilibrium model used in trade analysis.
Its specific neoclassical characteristics are that labor supply is a positi
ve function of the real consumption wage and that factor and product demand
s are price sensitive. We calculate the employment multipliers associated w
ith both a demand and supply stimulus to the basic sector. We demonstrate t
hat it is possible for the marginal economic base multiplier to take any po
sitive or negative value. However; the value of the marginal multiplier is
likely to approximate the value of the conventional average multiplier the
closer production and utility functions are to Cobb-Douglas specifications
and the more elastic is the labor supply function.
