The purpose of the present paper is to expand on the algebraic break-even point analysis relaxing the linearity assumption. Moreover, the model developed in the paper takes into account two potential situations concerning the volume of production: Production exceeds demand, a situation which bears implications for inventory considerations, i.e., part…

"Scheme rearrangement" was initially proposed to improve the fit and the robustness of a genetic algorithm. It was hypothesized that, in a problem comprising non linear or epistatic interactions, a greater efficiency would result from bringing closer the parameters of the interacting variables. The method was assessed, with mild success,…

Using the Panel Study of Income Dynamics data on the period 1982-1992, this paper investigates some mechanisms of the labor market in the United States. This market is analyzed as a stable structure constituted of segments which present contrasted characteristics under the usual distinction between primary and secondary sectors. Using…
