Mishael Milaković's work focuses on statistical equilibrium economic modeling. The concept of statistical equilibrium rests on the observation that economies are made up of a large number of heterogeneous agents whose interactions give rise to aggregate regularities in the form of statistical distributions, which routinely are neither foreseen nor intended by individual optimizing agents. The aim of his research is to detect distributional regularities and to understand which agent interactions are macroeconomically crucial in the sense that they do not cancel out in the process of aggregation.
Dr. Milaković has addressed these questions in the fields of finance and industrial organization, where key economic variables like financial returns, firm profit and growth rates, firm sizes, or income and personal wealth exhibit clearly non-Gaussian distributions. He also investigates how the network structure connecting agents influences distributional market outcomes, and how or why empirically observed economic networks come into existence in the first place.
