Accountability is the aspects of responsibility involving giving a statistical or judicial explanation for events. Judgement may follow.

Accountability classically appears (or should appear) in the ambit of accountancy.

In politics, and particularly in representative democracies, accountability is an important factor in securing good governance. Accountability differs from transparency in that it only enables negative feedback after a decision or action, while transparency also enables negative feedback before or during a decision or action. Accountability constrains the extent to which elected representatives and other office-holders can willfully deviate from their theoretical responsibilities, thus reducing corruption.
