Abstract
The article identifies differences between the ex ante treatment of costs in an Activity Based Costing (ABC) model and a model based on managerial economics. Under the ex ante model, ABC operates with both a consumption model and a spending model in activity-based budgeting. A numerical example is used to examine the significant differences between the models during periods of idle as well as scarce capacity in cases where costs are non-linear and, in practice, a compromise on the “ideal managerial economics” model is warranted.
