The expansion of international trade has influenced deeply many economies to converge (Slaughter 1998). Now a question can be raised whether the establishment of an economic union (a currency union, for instance) can lead to income convergence or it may cause income divergence between members of that union.
This paper examines whether the membership of countries in a block for trade expansion enables their economies to move toward income convergence, while the result should be different between countries in north, or north and south. To this end, the objective, the paper uses a difference-indifferences (DID) analysis to measure the rate of income convergence (divergence) before and after establishing a currency union. The results obtained approve that the implementing of currency union affects significantly and directly income convergence in the world, while this effect in much more pronounced in North-South countries than of North-South ones.

The central banks holding of the international reserves serves as a means for financing the balance-of-payments deficit, but bears opportunity costs. Therefore, the optimal level of the international reserves is one of the monetary authorities’ major concerns. The special economic conditions of the country, such as the severe dependency of the economy on the oil exporting revenues, lacking of the necessary flexibility in the foreign exchange market, commercial limitations and controlling the capital flows, limited access to the international financial markets, poor management of the foreign debts, and various national and international shocks to the economy in recent years have made the determining of the optimal level of the international reserves very important to the Iranian economy. In this paper, we use the Frankel-Jovanovic model which is based on the Bamol’s and Tobin’s buffer stock model and apply dynamic optimization and GARCH model to determine the optimal level of the international reserves of Central Bank of the Islamic Republic of Iran for the period 1961-2004. Our findings show that the real reserves level, except for the periods of high oil revenues, have been lower than the optimal level.
