This text examines the foundations and properties of the Generalized Production Functions frequently used in the literature devoted to the analysis of employment and duration of work in decentralized competitive economies. In order to improve the representation of the productive process, it introduces the concept of Output Density Function, then sketches some of its most direct applications : analyzing the determination of a two dimensional labor demand, explaining the impact of legally enforced working hour limits on employment and interpreting the Hicksian notion of "optimal working day".
