A growing number of studies suggest that accounting information risk, primarily idiosyncratic in nature, can be diversified away in the capital market. In this dissertation, I show that accounting information risk, proxied by accruals quality, is priced even if it is entirely idiosyncratic. In particular, building on a model from the ambiguity literature, I demonstrate that (1) in an under-diversified market, idiosyncratic information risk is priced even if it is diversifiable, and (2) in a well-diversified market, idiosyncratic information risk is priced when information is subject to managers' discretion and thus ambiguous. The empirical results corroborate the predictions from the model. Specifically, although an association is observed between (unambiguous if risky) innate accruals quality and cost of capital, the association can be largely mitigated through diversification. However, diversification has little impact on the association between (ambiguous) discretionary accruals quality and cost of capital. Taken together, these findings strengthen our understanding of the fundamental role of accounting information as a basis for capital allocation.
