Abstract<\/strong><\/strong>. <\/em>The paper presents a comparative analysis of the classical Cobb-Douglas production function, its transcendental-logarithmic specification, and modern machine learning techniques used to model production processes.
Aim<\/strong>. The paper aims to show how increasing the complexity of the real-world production function leads to the superiority of machine learning methods for forecasting quality compared to the traditional Cobb\u2013Douglas function, while still allowing for economic interpretation through the use of explainable artificial intelligence techniques.
Research materials and methods<\/strong>. A computational experiment was conducted with data including technological heterogeneity and nonlinear interactions between factors, ensuring an objective assessment of the accuracy of various approaches.
Results<\/strong>. It has been shown that the strict form of the Cobb\u2013Douglas production function leads to systematic errors when applied to complex production structures, while the Translog model partially compensates for these limitations by incorporating interactions between quadratic terms. Machine learning methods, such as gradient boosting and multilayer neural networks, demonstrate the best forecast quality due to their ability to approximate complex, nonlinear relationships and account for hidden factors. The paper also discusses the potential of using SHAP techniques to interpret machine learning models, which helps to recover economically significant relationships and increase confidence in the results.
Conclusion<\/strong>: The outputs confirm the possibility of integrating machine learning algorithms into modern economic models of production functions<\/p>\n\n\n\n
