The study examine whether a link exists between the Naira real exchange rate and macroeconomic performance and test for the existence of 'Balassa-Samuelson ' (1964) hypothesis in Nigeria. Using data covereing 1970 to 2009, the Parsimonious ECM result shows that the one period lag value of technological productivity has a negative sign and is statistically significant. This suggests the existence of the Balassa-Samuelson hypothesis in Nigeria. The Johansen Cointegration Test suggests a long run relationship among technological productivity, foreign private investment, the ratio of government expenditure to GDP and the real effective exchange rate. It is thus recommended that the government and policy makers should continue to employ policies that could increase productivity in all sectors of the economy to enhance exchange value of the Naira Keywords: Real exchange rate, cointegration, Balassa-Samuelson and Macroeconomic performance
IntroductionThe role of the real exchange rate in the economic performance of both developed and developing economies such as Nigeria constitutes one of the greatest macroeconomic policy debate. There is increasing agreement among economists and policy makers that while stability in the real exchange rate promotes economic growth and improved standard of living, misaligned real exchange rate hinders export growth and generates macroeconomic instability (Chowdhury, 1999). Thus, getting the exchange rate right or maintaining relative stability is critical for both internal and external balance and, hence growth in an economy. Failure to properly manage the real exchange rate induces distortions in consumption and production patterns particularly for an import dependent country. Fluctuations in real exchange rate have a destabilizing effect on the macro economy (Obadan, 2006). Private operators are also concerned about the exchange rate's fluctuations because it impacts on their portfolios, and may result in capital gains or losses (Balogun, 2007). This is because the real exchange rate reflects the international competitiveness as well as serves as nominal anchor for domestic prices. Real exchange rate misalignment affects economic activity in developing countries primarily due to the dependence of imported capital goods and specialization in commodity exports. Exchange rate policy guides investors in the best way they can strike a balance between their trading partners, and investing at home or abroad (Balogun, 2007).Despite various efforts by the government to maintain exchange rate stability in Nigeria (as well as avoiding its fluctuations and misalignment) in the last two decades, the naira exchange rate to the American dollar depreciated throughout the 1980s. For example, the naira depreciated from N0.61 in 1981 to N2.02 in 1986 and further to N8.03 in 1990. Although the exchange rate became relatively stable in the mid 1990s, it depreciated further to N120. 97, N129.36 and N133.50 in 200297, N129.36 and N133.50 in , 200397, N129.36 and N133.50 in and 200497, N129.3...
