Abstract: The levels of spatial interactions with certain types of public services, such as libraries and recreation facilities, may vary with the total numbers of opportunities available. Two partially constrained gravity models are developed that provide for this possibility of elastic demand. Circulation data for public libraries in Indianapolis, Indiana, are used to estimate the parameters of these models. The results show the presence of elasticity in the demand for library services.
