Econodynamics is a part of applied economics. It covers knowledge on monetary value, the usage of money, and the money flow. It deals with labor, and capital.

The concept of econodynamics has been applied in macroeconomic models that examine interactions among debt, investment, and financial instability. Some researchers use the term to describe dynamic feedback systems in which monetary flows, credit expansion, and asset prices mutually influence each other over time. For example, studies of nonlinear financial dynamics show how credit growth and asset valuation can reinforce each other, potentially leading to instability in leveraged economies. Similar approaches also examine how monetary circulation interacts with production and consumption flows, using system-dynamics models to understand long-run disequilibria in capitalist economies.
