Economic essence and method of elasticity coefficient calculation

Research relevance: in the economic literature and scientific works of domestic and foreign researchers, the issues of assessing elasticity indicators based on the actual materials of economic entities are poorly researched. At the same time, the study of elasticity is an urgent task, as it contributes to the adoption of rational management decisions. Research objectives: is to identify the relationship between the productive and factor signs of socio-economic phenomena, namely between advertising costs and revenue from the sale of products based on materials of the same type of enterprises for making optimal management decisions. Research materials and methods: economic-mathematical, statistical methods were applied to calculate coefficient of elasticity. Research results: elasticity coefficients and beta coefficients were calculated, allowing to determine a moderate relationship between them, and based on the results of the analysis, an economic interpretation of the obtained indicators was given. Conclusions: there is a moderate relationship between advertising expenses and sales volume based on the Chaddock scale.
