In this paper, based on error correction model by using panel data, an empirical analysis of demand for international reserves for 16 Islamic countries is investigated. Besides addressing conventional issues, the model explicitly incorporates the impact of expected export revenues and the impact of the exchange rate system on reserve demand. The results reveal that, short run money market diseq...

the purpose of establishing foreign reserves account in iran was mainly to secure iran's economy from the oil's price changes. it was to compensate for oil price reduction. but foreign reserves account withdrew excessively and did not allocate it optimally. that's why; it went for away from its practical purpose. this study focuses on the use of official assessment pattern to rev...

Wildlife corridors can help maintain landscape connectivity but novel methods must be developed to assess regional structural connectivity quickly and cheaply so as to determine where expensive and time-consuming surveys of functional connectivity should occur. We use least-cost methods, the most accurate and up-to-date land conversion dataset for East Africa, and interview data on wildlife cor...

In the post-COVID-19 era, market for emergency medical supplies has shrunk, and related production capacity is rapidly overcapacity.The supply chain at risk of interruption. First, we analyzed decision-making behavior members from perspective evolutionary game, used probability density function to transform game model into a sharp mutation model; secondly, simulated impact factors such as coope...
