Abstract

fetched live from OpenAlex

The study examines the optimum threshold effects of interest rates, inflation rates, and exchange rates in stimulating economic growth in Nigeria. The study adopts the threshold regression technique to ascertain the optimal benchmark beyond which these macroeconomic variables hurt growth. The results of interest rate-economic growth thresholds suggest targeting an average monetary policy rate of 16.5%, a prime lending rate of 20%, and a maximum lending rate of 30%. The results of inflation-economic growth thresholds suggest targeting a headline inflation rate of 9%, while core inflation of 8.7% and food inflation of 12.7% are all growth-enhancing for Nigeria. Lastly, the results of exchange rate-economic growth thresholds suggest that targeting a quarterly depreciation of not more than 2.4% for the official exchange rate and a quarterly depreciation of not more than 2.5% for the unofficial exchange rate are growth-enhancing for Nigeria. The results offer policymakers valuable insights, emphasising the significance of exchange rate management, interest rate management, and inflation rate management in promoting growth and emphasising the necessity of reforms to diversify exports, strengthen institutions, and improve the efficacy of monetary policy. Therefore, the study suggests that the Nigerian government should target the obtainable thresholds for growth to become sustainable.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
