CHAPTER ONE INTRODUCTION 1.1 BACKGROUND OF THE STUDY Since exportation has a special share in the economic growth of many advanced and developing countries; as far as making those countries as the strongest countries, the effective factors; in turn, could pave way for progress of countries, particularly the developing countries. Since increase or decrease in currency exchange rate leads to the decrease or increase in export. Nigeria is endowed with various kinds of resources needed to place her amongst the top emerging economies of the World. Unfortunately, the nation has not adequately benefited from the economic prosperity expected of a nation so richly blessed. Non-oil exports are products, which are produced within the country in the agricultural, mining, quarrying and industrial sector that are sent outside the country to generate revenue for the growth of the economy, excluding oil products. These non-oil exports include products like coal, cotton, timber, groundnut, cocoa, beans, gum arabic etc. while real exchange rate basically, can be defined as the nominal exchange rate that takes the inflation differentials among the countries into account. Its importance stems from the fact that it can be used as an indicator of competitiveness in the foreign trade of a country. Exchange rate is used to determine an individual country’s currency value relative to the other major currencies in the index, as adjusted for the effects of inflation. All currencies within the said index are the major currencies being traded today: U.S. dollar, Euro pounds, etc. This is also the value that an individual consumer will pay for an imported good at the consumer level. This price includes tariffs and transactions costs associated with importing the good. It is imperative to note that exchange rate, whether fixed or floating, affects macroeconomic performance such as import, export, national price level, output, interest rate etc as well as economic units such as individuals’ purchasing power, firms’ performance etc (Chong and Tan, 2008). Chong and Tan (2008) empirical analysis revealed that the real exchange rate volatility is responsible for changes in macroeconomic fundamentals for the developing economies. Export earnings assume vital importance not only for developing, but also for developed countries. Developed countries mainly export capital and final goods, while the main part of export of developing countries consists of mining-industry goods especially natural resources. According to export-led growth hypothesis increased export can perform the role of “engine of economic growth” because it can increase employment, create profit, trigger greater productivity and lead to rise in accumulation of reserves, allowing a country to balance their finances (Emilio (2001), Goldstein and Pevehouse (2008), Gibson and Michael (1992), McCombie and Thirlwall (1994)). In this context there are some challenges for countries with natural resource abundance such as oil in comparison with other countries. The main point is that in parallel with windfall of oil revenues these countries have to pay more attention to the development 2 of the non-oil sector as well as its export performance (Sorsa, 1999). Because in the most of the cases oil driven economic development leads to some undesirable consequences such as Dutch Disease in the oil rich countries. In this regard Dutch Disease concept provides certain link between the real exchange rate and non-oil export. According to this concept the appreciation of a country’s real exchange rate caused by the sharp rise in export of a booming resource sector draws capital and labour away from a country’s manufacturing and agricultural sectors, which can lead to a decline in exports of agricultural and manufactured goods and inflate the price of non-tradable goods Corden (1982) and Corden and Nearly (1984). The discovery of oil and the realization that foreign exchange could comparatively be easily derived from relegated attention to the non-oil sector to the background. There are some motivations for conducting this research. The main motivations is that some seminal theoretical and empirical studies predict that most natural resource rich countries suffer from serious socio-economic problems caused by their resource revenues and in this regard these natural revenues are a curse rather than a blessing for these countries (Sachs and Warner, 1997; Auty, 2001; Gylfason, 2001; Gylfason and Zoega, 2002 ). One of these resources causes, the so called Dutch disease, is mainly related to an appreciation of the real exchange rate, sourced from inflow of resource revenue into country, which undermines the competitiveness of the non-resource sector’s (manufacturing and agriculture) export and therefore deteriorates this sector while it leads to higher demand for imports and services ...
