A test of the fisher effect in Nigeria
The â€œFisher Effectâ€ has stimulated enormous research interest, especially in monetary policy. Expectedly, empirical evidence has varied greatly â€“ from absence of effect to strong effect. This has kept the debate alive, with the benefit of fresh policy-relevant insights and clues especially in developing countries where the literature on the subject is fast growing. This paper contributes to the debate by using the state space model to investigate the dynamic relationship between real interest rate and inflation in Nigeria. The paper reveals varying degrees of effect across interest rate and time horizons.
