The effects of profit-sharing plans, client importance, and reinforcement sensitivity on audit quality

Despite concerns that profit-sharing plans might have a detrimental effect on audit quality, there is little empirical evidence on this issue. We examine the effects of the type of profit-sharing plan, level of client importance, and auditor reinforcement sensitivity ( joint sensitivity to rewards and punishments) on auditor reporting decisions. By relying on agency theory and reinforcement sensitivity theory, we posit that the joint effects of profit-sharing and client importance on auditors’ decisions are contingent on reinforcement sensitivity. In an experiment with 450 audit partners and managers, we manipulate type of profit-sharing plan and client importance, and measure extroversion and neuroticism. We find the highest audit quality when profit-sharing is based on firm performance, client importance is low, and reinforcement sensitivity is high. Thus, instead of just modifying the type of profit-sharing plans, it is the mix of economic incentives and personality traits that affect audit quality.
