This study investigates the relationship between corporate fraud and four typical components of costs associated with corporate bonds. Based on data from a booming corporate bond market in China, we confirm that fraudulent issuers have higher corporate bond costs. Specifically, they are more likely to push upward price revisions, pay higher issue fees and coupon spreads, and encounter larger underpricing after issuance. Moreover, we demonstrate that severe corporate fraud is also significantly related to the costs of corporate bonds. Furthermore, we find that investors pay more attention to fraud in accounting information and disclosure. These results remain robust to a strand of endogeneity and through the robustness tests. In additional research, we find that bonds issued by fraudulent firms tend to receive lower ratings and show inferior performance after issuance. We also demonstrate that the effects of corporate fraud on bond costs erode as time passes, although the mitigation speed is slow. Finally, we find that hiring reputable financial intermediaries can partially mitigate the negative effects of corporate fraud.

Corporate adoption of technology faces challenges such as resource constraints and litigation risk. To investigate if low litigation risk encourages technology adoption and its use, this paper investigates corporate financial reporting on Twitter, a voluntary corporate disclosure practice without obvious litigation risk in Australia. This study reviews 4,540 financial reporting related tweets from 222 ASX listed companies’ Twitter accounts. An examination of tweet sentiment reveals a positive reporting bias, as listed companies are more willing to disclose positive financial reporting information on Twitter. A comparison of corporate financial reporting tweets prior to and after 2013 reveals that use of Twitter for opportunistic voluntary disclosure is gaining popularity, a trend that warrants close attention by regulators in order to protect investors from selective disclosure with reporting bias.

Improving the transparency of corporate information disclosure is a key principle of corporate governance in Taiwan. This study uses the information disclosure assessment system established by the information disclosure and transparency ranking system to explore whether information transparency can reduce the degree of mispricing. The study uses the data of 10,686 listed companies in Taiwan for the period from 2005 to 2014. We find that a higher information disclosure ranking (IDR) of rated companies corresponds to a more substantial reduction in the degree of mispricing. Moreover, we discover that product market competition affects mispricing in that smaller degrees of mispricing reflect greater exclusivity; this suggests that lower industry transaction and competition costs lead to less substantial mispricing. Finally, we observe that the effect of information disclosure score on the degree of mispricing is lower in more exclusive industries. Furthermore, a regression process using instrumental variables reveals that IDRs have the significant effect of reducing the degree of mispricing.

Uber is a prominent example of the sharing economy and a key player in the transportation service market. In this paper, we investigate how Uber adopts a dynamic pricing system in its compensation structure design for driver rewards. A longitudinal and citywide comparison of the Uber driver reward system reveals that Uber reacts to local taxi conditions in China by creating different reward conditions in unique city environments in response to taxi possession rates. The dynamic pricing model embedded in the Uber driver reward system benefits hardworking drivers (particularly during peak periods) and those who provide a friendly and efficient service experience for passengers. In addition, we identify significant benefits introduced by Uber including significantly improvement of driver remuneration and reduction of the taxi plate subscription premium. These findings contribute evidences of the utility of dynamic pricing systems, especially in compensation structure design, as well as positive influences introduced by sharing economy in tackling taxi service market monopoly.
