Research Article of Journal of Theoretical and Applied Economics ESTIMATION OF THE SACRIFICE RATIO BETWEEN INFLATION AND GROWTH IN NIGERIA Abidemi S. Abdulsalam; Samuel F. Onipede; Godday U. Ebuh West African Monetary Agency; Central Bank of Nigeria. Relying on the adaptive expectations Augmented Phillips Curve approach, the study estimated the sacrifice ratio for inflation that is conducive for growth in Nigeria and found the ratios for the constructed models I and II to be positive. The sacrifice ratio measures how much output is lost in the country when inflation is reduced by 1 percentage point through monetary policy action. The outcome of our study suggests that a 1 percent disinflation accomplishment leads to an output loss of 0.07%. Also, for a given period, power of persistence effect coefficient is 0.71 on the average, suggesting that, disinflation policy has a more robust and long-lasting impact on the country’s real GDP.

Research Article of Journal of Theoretical and Applied Economics Studying the Correlation of Stocks via Copula Function Yishuai Tian1, Boying Lv1, Botao Liu1 1College of Hydraulic & Environmental Engineering, China Three Gorges University, Yichang 443002, China. Many factors affect the value of stocks, but there are few studies on the correlation between stocks and stock indexes. Therefore, this paper selects the closing prices of 4 industries related to Everbright Bank (601818) and 15 sectors related to the market index from 2017 to 2018, carries on the correlation analysis based on the Copula function, and compares the correlation coefficient by calculation. The stocks closely related to Everbright Bank are mainly bank stocks such as Bank of China and Ningbo Bank, while those greatly affected by the Shanghai Composite Index are Yunnan germanium industry, Tongji Technology, Futian Automobile and other technology and manufacturing stocks. Based on the Copula function to explore the correlation between stocks and the influencing factors, to provide a specific research basis for stock correlation analysis.
