This paper examines the impact of demand on the location decision of a
monopsonistic firm in the Weber-Moses triangle with one output and tw
o inputs. When the distance of the plant location from the product mar
ket is held constant and the expansion path is linear through the orig
in, the analysis shows that as demand for output increases, the monops
onist has an incentive to move the plant away from the monopsonized in
put market and towards other markets. When the distance of the plant l
ocation from the product market is a choice variable, the linearly hom
ogeneous production function is not sufficient to ensure that the loca
tion decision of the monopsonistic firm is independent of the demand f
unction, These results differ significantly from the well-established
results in location theory where the firm is a price taker in all the
input markets.
