The main thrust of this Element is a critical assessment of the theory and evidence concerning the sources of scale effects. It is argued that the analysis of static scale effects is important because scale effects are embedding in our world, and new technologies associated with an evolving...

The paper is divided into two parts: one-dimensional markets and two-dimensional markets. Also, we develop both one and two-dimensional models. Within each, we distinguish (a) bounded, (b) unbounded but finite, and (c) unbounded, infinite spaces. Among other things, we show: in one dimension,...

On an infinitely-extensible plane (with uniform customer-density) the socially-optimal configuration of firms is a regular hexagonal lattice. Will the free market necessarily produce this configuration? We argue that the currently-accepted, affirmative answer has been erroneously derived from...
