| Abstract: | Accounting discretion and the principle of conservatism are two salient features embedded in financial reporting systems. Arguably, the practice of conservative accounting choices can never be well understood without incorporating their effect on future periods (the intertemporal effect). This paper provides one explanation for managerial conservatism in a two‐period agency model with hidden information (a binary project type) and hidden actions (the agent's efforts). A piece‐wise linear incentive scheme with accounting earnings as the performance measure is employed. The agent's discretion is the choice of a depreciation method. Discretion is valuable if and only if the agent's marginal productivity of a “bad” project is greater than that of a “good” project, but not to an extreme degree. A conservative depreciation method decreases current compensation in exchange for a “bet” on future compensation and, hence, serves as a commitment device for the agent to signal that the prospect is indeed good. The accounting mechanism replicates the performance of the optimal direct mechanism. |
