Foreign capital flows are important factors in the development of sustainable economies, especially in developing countries such as the OIC countries. Lately, the rapid development of the financial sector and macroeconomic stability became a serious concern by foreign investors, where financial inclusion and macroeconomics played an important role in attracting direct foreign capital flows (FDI). The study aims to investigate the role of financial inclusion and macroeconomic variables on the foreign direct flow of capital (FDI) by using data panels in 8 OKI member States during the 2012-2018 time span. The research uses the Fix Effect Model (FEM) Panel data Analysis tool, which is believed to be able to explain the correlation between independent variables and more accurate dependents. As for the results of the study showed that in partial only variable avaibility (the number of branches of the bank/100,000 adults) is a significant positive draws FDI in the OKI country. While on macroeconomic variables the exchange rates have significant negative effect on FDI, while interest rates and economic growth have significant positive relationships in attracting FDI.

The growth of Islamic finance in Indonesia has experienced very significant growth. The Indonesian government hopes that the financial sector will become an important instrument in promoting economic growth in Indonesia, but it seems that the percentage of economic growth in Indonesia has declined over the past decade. This study aims to analyze the impact of Islamic financial instruments on economic growth in Indonesia. This study uses a quantitative method with an Autoregressive Distributed Lag (ARDL) model analysis tool. The results of this study show that all Islamic financial instrument variables have a negative effect on economic growth in the short term. Meanwhile, in the long term, all independent variables have a positive effect on economic growth except for Sharia Mutual Funds which show a negative effect and Sharia Bank Financing and Sharia Stocks have no effect on economic growth in Indonesia. Thus, it can be concluded that Islamic financial instruments in the long term have a positive influence on encouraging economic growth in Indonesia.

-The presence of information asymmetry increases transaction costs and reduces liquidity, and reduces the quality of investment decisions taken by investors. So that in turn it weakens the overall function of the market. Accounting disclosure plays a role in mobilizing information from management and investors so as to reduce information asymmetry. In addition, it is hoped that the presence of a concentration of investor ownership can carry out internal monitoring of the company so as to reduce information asymmetry. On the other hand, institutional investors have many incentives to access company information for their trading purposes due to the conflict of interest between outside investors and the board of directors. This study aims to determine the effect of disclosure quality and ownership structure on information asymmetry in companies listed on the Jakrta Islamic Index (JII) during the 2015-2019 period. Based on the results of panel data analysis of the Fixed Effect Model (FEM), it was found that institutional ownership had a significant positive effect on information asymmetry, while the quality of disclosure and ownership concentration did not have a statistical effect on information asymmetry.
