  • The purpose of this study is to empirically analyze whether the influence of foreign investors from the monitoring role in Korean capital market is observed differently in accordance with the global financial crisis situation. We collected a total of 2,919 firm data from 2003 to 2015 and performed the empirical tests between foreign investor ownership and firms' cost of equity capital separately according to the situation of the global financial crisis. From the empirical results, foreign investors in general were playing a positive function in the Korean capital market by effectively performing the monitoring role for companies. However, we observed that their monitoring role is not effectively performed when the risk level of capital market is maximized, such as during the global financial crisis. The study suggested that the influence of foreign investors may vary depending on the level of risk in the capital market, which is expected to contribute to the market participants and academia.

  • To implement crowdsensing system in reality, trustiness between service provider server and user is necessary. Service provider server could manipulate the evaluation of sensing data to reduce incentive. Moreover, user could send a fake sensing data to get unjust incentive. In this paper, we adopt private blockchain on crowdsensing system, and thus paid incentives and sent data are unmodifiablely recorded. It makes server and users act as watcher of each others. Through adopting smart contract, our system automates sensing data evaluation and opens to users how it works. Finally, we show the feasibility of proposing system with performance evaluation and comparison with other systems.
