Cost accounting is defined by the Institute of Management Accountants as "a systematic set of procedures for recording and reporting ... By behavior: fixed, variable ...
The behavior of both costs and revenues is linear throughout the relevant range of activity. (This assumption precludes the concept of volume discounts on either purchased materials or sales.) Costs can be classified accurately as either fixed or variable. Changes in activity are the only factors that affect costs.
The total cost curve, if non-linear, can represent increasing and diminishing marginal returns.. The short-run total cost (SRTC) and long-run total cost (LRTC) curves are increasing in the quantity of output produced because producing more output requires more labor usage in both the short and long runs, and because in the long run producing more output involves using more of the physical ...

Optimality models are used to predict optimal behavior (ex. time spent foraging). To make predictions about optimal behavior, cost-benefit graphs are used to visualize the optimality model (see Fig 1). Optimality occurs at the point in which the difference between benefits and costs for obtaining a currency via a particular behavior is maximized.
This grows worse with firm size and more layers in the hierarchy. Empirical analyses of transaction costs have attempted to measure and operationalize transaction costs. [5] [27] Research that attempts to measure transaction costs is the most critical limit to efforts to potential falsification and validation of transaction cost economics.
The transaction costs frameworks reject the notion of instrumental rationality and its implications for predicting behavior. Whereas instrumental rationality assumes that an actor's understanding of the world is the same as the objective reality of the world, scholars who focus on transaction costs note that actors lack perfect information ...
The majority of costly signaling explanations involve behaviors that broadcast beneficial traits about oneself to others. [17] In many instances, these signals are expected to be directed towards potential mates, with males often thought to benefit more from such signaling due to their relatively low levels of investment in offspring leading to greater fitness benefits in having multiple partners.
