Outline of Final Research Achievements

We proposed a model and solution concepts that describe why stakeholders accept specific depreciation procedures using cooperative game theory. First, we considered the core concept as a solution that provides the scope of acceptable payoffs for the players. The result shows that the conventional straight-line (SL) method is always accepted under practical conditions. In contrast, the fair value measurement is accepted only if the firm can obtain a precise market value for the asset. Next, we simulated the conditions that the SL method is mainly accepted using the Shapley value. We proved that the Shapley value does not strictly explain the rationality of the SL method but we got a conjecture that the longer the depreciation period is, the smaller the unexplainable factor with the Shapley value is. We will prove this near future.
