This research was aimed to analyze the impact of the Iraqi dinar exchange rates for the period 1990-2020 on the imported quantities of rice crop, and to measure the price elasticity of demand for this crop. The (ADRL) model was applied to measure the impact of these prices in addition to the (international price).After conducting the statistical tests (Dickie Fuller test) to examine the stability of the time series of the studied variables included in the model, which stabilized after taking the first difference for them, the results of the analysis showed that international prices had a weak effect on the imported quantities of rice crop, and that these quantities increased at an annual growth rate 6% more than the increase in the annual growth rate of foreign prices amounting to 2%, because the rice crop is one of the basic food crops in the Iraqi consumer list and that it is included in the items of the ration card distributed to individuals and therefore it is imported by the state to meet the need regardless of the rise in its prices. The private sector also imports high-quality brands regardless of prices. As for the equilibrium exchange rate, which is usually higher than the nominal exchange rate adopted by importers in obtaining foreign currency from unofficial markets, the higher the exchange rate, the lower the quantity imported, and the fixation of the nominal exchange rate for many years had a positive impact on the quantities imported by The government, so it is necessary to set an exchange rate for the Iraqi dinar that takes into account the purchasing power towards importing basic food commodities on which the community depends entirely for nutrition.

Foreign aid flows to poor, aid-dependent economies are highly volatile and pro-cyclical. Shortfalls in aid coincide with shortfalls in GDP and government revenues. This increases the consumption volatility in aid dependent countries, thereby causing substantial welfare losses. This paper finds that indexing aid flows to exogenous shocks like a change in the terms of trade can significantly improve the welfare of aid-dependent country by lowering its output and consumption volatility. Compared to the benchmark specification with stochastic aid flows, indexation of aid flows to terms of trade shocks can reduce the cost of business cycle fluctuations in the recipient country by four percent of permanent consumption. Moreover, use of indexed aid can allow donors to reduce the aid flows by three percent without lowering the level of welfare in the recipient country.

We combine georeferenced data on mining extraction of 14 minerals with information on conflict events at spatial resolution of 0.5° × 0.5° for all of Africa between 1997 and 2010. Exploiting exogenous variations in world prices, we find a positive impact of mining on conflict at the local level. Quantitatively, our estimates suggest that the historical rise in mineral prices (commodity super-cycle) might explain up to one-fourth of the average level of violence across African countries over the period. We then document how a fighting group's control of a mining area contributes to escalation from local to global violence. Finally, we analyze the impact of corporate practices and transparency initiatives in the mining industry.

This paper investigates the behavior of Korean trade flows during the last three decades and presents estimates of aggregate export and import equations. In particular, it considers different choices for scale and price variables and assesses the relative merits of these alternative specifications in terms of stability and forecasting performance. It also provides an assessment of the drastic change in the geographical destination of Korean exports during the 1990s.

This paper examines the impact of the 2003-05 oil price increase on the balance of payments positions and IMF financing needs of low-income country oil importers. It finds that stronger exports reflecting favorable global conditions, a compression of oil import volumes due to the pass-through of world prices to domestic consumers, and a large increase in capital inflows helped low-income countries cope with the oil price shock. Preliminary data suggest that reductions in oil import volumes have not harmed growth. While fiscal balances generally improved, quasi-fiscal liabilities may be building. Lower demand for IMF assistance may reflect broader trends, but further oil price increases could put pressure on additional countries in 2006 and beyond

This paper explores the role of trade instruments in globally efficient climate policies, focusing on the central issue of whether some form of border tax adjustment (BTA) is warranted when carbon prices differ internationally. It shows that tariff policy has a role in easing cross-country distributional concerns that can make non-uniform carbon pricing efficient and, more particularly, that Pareto-efficiency requires a form of BTA when carbon taxes in some countries are constrained, a special case being identified in which this has the simple structure envisaged in practical policy discusions. It also stresses-a point that has been overlooked in the policy debate-that the efficiency case for BTA depends critically on whether climate policies are pursued by carbon taxation or by cap-and-trade.

Based on a simple model, the paper provides an explanation for illegal oil trade between Nigeria and its neighboring countries. The analysis focuses on the linkages between the level of smuggling and changes in the Government's fiscal, monetary, and domestic pricing policies. It is shown that smuggling has implications for inflation and currency depreciation. A vicious circle emerges when financial policies are expansionary and policy makers attempt to hold the domestic sale price of oil constant. Macroeconomic indicators of Nigeria over the period 1986-1993 appear to support the predictions of the model. Policy implications of the analysis are also noted.
