It has become one of the major problems that most countries of the world are exposed to، because of its significant effects on the economic، social، and political conditions. For the country، this research aims to investigate the determinants of unemployment over the time period (2004-2021)، by identifying the most important of these determinants، as well as contributing to the economic process and eliminating part of the unemployment rates that Iraq suffers from، which represent a security and economic threat، as The research problem is represented by the continuous rise in unemployment rates. The research is based on the hypothesis that “there is an inverse relationship between economic determinants and unemployment rates.” The study reached many results، the most important of which is the existence of an inverse relationship between inflation rates، gross domestic product، public expenditures، and exchange rates.

Therefore, it is possible to know the status of the country’s trade balance if it is in favor of exports, and this means achieving a surplus, and if it is in favor of imports, then it achieves a deficit. The exchange rate is one of the most important monetary policy tools that the state has to protect the national economy from the external influences to which it is exposed. Therefore, the importance of the research comes from the necessity of explaining the economic effects of exchange rate systems and their role in developing commodity exports. As for the research problem, it has shown the extent of the impact of exchange rate systems as a variable. It is independent in the dependent variable represented by merchandise exports, while the research hypothesis focused on an important question: Do exchange rate systems have an impact on the overall national economy? The research aimed to demonstrate the impact of the exchange rate on commodity exports to Iraq. The research methodology in the analysis was based on shifting from the deductive approach in analyzing the theoretical side of the research to the inductive approach that aims to estimate the efficiency of commodity exports through statistical data. The research concludes with the standard statistical approach and the use of standard analysis methods by relying on a program to analyze data on exchange rate fluctuations and their impact on commodity exports to Iraq. The research relied on temporal and spatial boundaries. The temporal boundaries covered the time period between 1990 and 2019, while the spatial boundaries focused on Iraq. The structure of the research consisted of three sections: The first section: The theoretical framework of the exchange rate system. The second section: The development of drainage systems in Iraq. The third topic: the reality of commodity exports in Iraq. The fourth topic: econometric analysis of the data under study.","PeriodicalId":181022,"journal":{"name":"Al Kut Journal of Economics and Administrative Sciences","volume":"42 173","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140237016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, these two variables are the tool for linking the value of goods, assets, and wages in the local markets, and their counterparts in foreign markets, and through them many relationships arise. International, the most important of which is the possibility of directing and transferring capital to one country and not another, as these two variables (interest rate, exchange rate) have a direct role in international transactions. Through the interaction of the interest rate and the exchange rate, we have an economic relationship that has a direct impact on the flow of foreign investments between countries. Therefore, these concepts and their relationship to the overall economy and what are the most prominent factors affecting them will be discussed. The study sought to demonstrate the impact of these two variables on the Iraqi economy through the research objective. The research aims to describe and analyze the paths of interest rates and exchange rates during the period (2004 - 2020) in order to determine their behavior during the research period. The most prominent conclusions reached by the research were that the exchange rate is considered a measure of international competitiveness, which exerts a major influence on the local economy, as does the interest rate, as it reflects the economic position in general, and commercial position in particular, because it represents the linking tool through which prices are determined. The relative proportion of local goods to foreign goods. That is, it is the linking tool through which the purchasing power of the local currency is determined against other foreign currencies, as the local currency is considered a commodity, and the foreign currency is its monetary price.

In this case, the organization resorts to reducing prices, and this is reflected in a decrease in its profits, which weakens its competitive ability.
