This thesis extends the literature on institutional accounting by providing a new channel---proprietary information leakage between competitors---through which institutions affect accounting attributes and information disclosure. Weak property rights protection exacerbates outflow of proprietary information on operation, thus reduces managers' incentive to disclose financial information and other operation related information since the disclosed information will be helpful for competitors to learn more about proprietary information on operation of the firm. The channel is built with two links. One is the link between property rights protection and R&D spillovers, which proxy for proprietary information disclosure, and the other is the link between R&D spillovers and transparency. Empirical results show that R&D spillovers are negatively associated with regional property rights protection. In addition, I find that innovation output depends less on in house R&D investment and more on R&D spillovers from competitors in regions with weak property rights protection than in regions with strong protection and that the level of R&D expenditures is positively associated with property rights protection. Some evidence is found that firms with more R&D spillovers are more likely to have opaque earnings and disclose less firm-specific information. The relationship is stronger in regions with weak property rights protection than in regions with strong protection, indicating that firms are more likely to utilize opacity to prevent proprietary information leakage when R&D spillovers are large. / Yu, Xin. / Adviser: Joseph P.
