The article introduces a simple behavioral model for simulating the dynamics of a small economy, that is a member of the Economic and Monetary Union (EMU). The model takes account, among others, of the process of nominal convergence of prices in the EMU and its impact on the trade balance, the evolution of prices depending on the level of stocks and flows of financial capital. With the help of certain methods of analysis of systems of differential equations, we are examining the conditions for stability of the economy. We show that they have the form of certain restrictions on behavioral parameters, which reflect the strength of the reaction of economic agents to imbalances. To illustrate these proposals, we carry out computer simulations. Finally, we present a dynamic analysis of the process of transition between two states of equilibrium, induced by fiscal expansion.
