本文构建了一个在给定中心购物的最佳频率的效用最大化模型，当有机会通过与非购物目的的旅行（例如上班的旅行）共享来降低旅行成本时，其频率是有规律的和外生的。由于如果这些频率相同，联合经济的可能性会造成成本的不连续性，因此开发了一种特殊的算法来计算最佳购物频率。该算法通过求解模型关键参数的一系列变化来说明。结果表明，最佳购物频率虽然能够随这些参数连续变化，但却是不连续变化的。
The paper constructs a utility-maximizing model of the optimum frequency of shopping at a given centre, when there are opportunities for reducing travel costs by sharing with trips for non-shopping purposes, such as the trip to work, whose frequency is regular and exogenous. Because of the discontinuity in costs, created by the possibility of joint economies if these frequencies are the same, a special algorithm is developed for calculating the optimal frequency of shopping. The algorithm is illustrated by solving the model for a series of variations in the crucial parameters of the model. It is shown that the optimal frequency of shopping, although able to vary continuously with such parameters, varies discontinuously.
