This paper examines the determinants and economic efficiency of corporate voluntary disclosure. The focus is on the trade-off for an individual firm when the costs and benefits of voluntary disclosure stem from the consequences of its investment decisions and the impact on its share price. Investment and voluntary disclosure decisions are intertwined. First, voluntary disclosure leads to more accurate pricing, which induces more efficient investment decisions. Second, the firm may affect the market pricing in its favor by strategically disclosing or withholding its private information. This opportunistic use of disclosure may cause the real investment to be distorted at the margin. My analysis shows that the efficiency of voluntary disclosure is influenced by both effects. Further, this paper investigates how the investment efficiency and the propensity for providing voluntary disclosure respond to various environmental variables. Two such key variables are the general economic outlook of the investment opportunity and the quality of firm private information.

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.

In this study, we show that when a firm needs external financing, information quality has real effects via financing contracts on the firm's input to influence its operational outcome. Interestingly, we find that higher information quality decreases overall efficiency. Our analysis highlights the importance of considering the role of information quality in the presence of the firm's input decision upon financing contracts. In particular, information quality has a feedforward effect on the firm's real input decision via financing contracts, which in turn has a feedback effect on financing contracts and overall efficiency.
