Financial Leverage, Information Quality, and Efficiency*
研究了企业家在需要融资进行风险项目时，信息质量与财务杠杆如何共同影响其努力投入和投资决策，发现杠杆与最优信息质量正相关。
ABSTRACT We examine information quality and financial leverage when an entrepreneur needs financing to undertake a risky project and his effort input affects the project's outcome. We show that information quality and financial leverage interact to play active roles in both investment and effort decisions. Our analysis shows a positive association between leverage and optimal information quality—when leverage is low (high), low (high) information quality is optimal. This is because with low leverage, the entrepreneur is already motivated by his large share of the outcome to exert effort, and high information quality is not efficient as a precise bad signal discourages the entrepreneur's effort. In contrast, when leverage is high and thus the entrepreneur is less motivated by his residual cash flows, high information quality is optimal, because a precise good signal encourages the entrepreneur's effort. Our study highlights the joint effect of information quality and financial leverage on overall efficiency through firms' effort inputs as well as on defining investment efficiency.
