Query: Spatial competition and price formation   We look at price formation in a retail setting, that is, companies set
prices, and consumers either accept prices or go someplace else. In contrast to
most other models in this context, we use a two-dimensional spatial structure
for information transmission, that is, consumers can only learn from nearest
neighbors. Many aspects of this can be understood in terms of generalized
evolutionary dynamics. In consequence, we first look at spatial competition and
cluster formation without price. This leads to establishement size
distributions, which we compare to reality. After some theoretical
considerations, which at least heuristically explain our simulation results, we
finally return to price formation, where we demonstrate that our simple model
with nearly no organized planning or rationality on the part of any of the
agents indeed leads to an economically plausible price.
