Remittances are one of the financial inflows that can affect the economic growth of emerging and developing countries through the exchange rate volatility channel. Many small open economies are vulnerable to volatilities and changes in capital inflows so that sudden changes in the exchange rate can affect economic growth negatively by declining investment, trade volume, and profitability. In this study, the effect of the factors that have an impact on the real exchange rate volatility has been investigated and empirically analyzed by using Generalized Autoregressive Conditional Heteroskedasticity (GARCH) and Panel Vector Autoregressive (P-VAR) approaches in the selected developing countries including Iran over the period 1980-2017. The results indicated that remittances had a positive and significant effect on the exchange rate volatility of the studied countries so that an increase in remittances caused volatilities in the real exchange rate. In addition, among other explanatory variables, foreign direct investment and government expenditures had the most negative and positive effects on real exchange rate volatilities respectively.

One of the issues discussed in geopolitics is the role of international straits (canals); as such, it is of great importance to investigate their geopolitical and strategic role. It is because the straits are the places of distribution of power, where the competition of governments is very evident in using the potential of geographic space to achieve greater benefits and ultimately to gain power in international relations. Even in some cases, countries not located around the straits enter many ways in order not to lag behind other countries. That is to say, there is a kind of conflict and competition between countries over the use of straits, especially the countries bordering the strait. Therefore, the strategic straits play a decisive role in the power of nations and their fate and also in the foreign policy of the coastal states along with the balance of regional and global power, as a result, their study is essential for political geographers and geopoliticians. One of the most important straits in the world is the Malacca Strait whose investigation strategically and geographically provides important points. Using descriptive-analytical method and also based on statistics and figures for plotting diagrams in this paper, it has been tried to study the role, geopolitical features, and importance of Malacca Strait for coastal states and conditions as well as factors causing challenges and crises for the strategic role of the strait. According to the results, as one of the major international straits, the Malacca Strait has strategic potentials in the regional and global arena and coastal governments need to rely on targeted and strategic plans to combat the challenging processes in this strait<strong>.</strong>
