SCAFFOLDING EFFECT

psychology

Diseconomies of Scale

Diseconomies of scale refer to the phenomenon where, as a firm expands its production scale, marginal benefits gradually decline, even falling below zero and becoming negative. This may be caused by the increasing complexity of internal structures as scale expands, which consumes internal resources, offsetting the benefits that scale expansion should bring, thus leading to diseconomies of scale. In economics, there are total cost curves and average cost curves, both of which are concave upward. The intersection of these two curves signifies the existence of an optimal scale.
