Rule-Based Profit Taxation in Dynamic Cournot Oligopoly: Transmission, Stability and Welfare - replication code

This dataset contains the MATLAB replication package for the article *“Rule-Based Profit Taxation in Dynamic Cournot Oligopoly: Transmission, Stability, and Welfare”*. The code implements the discrete-time bounded-rationality Cournot oligopoly model with a welfare-based, rule-updated profit tax rate and an effective tax transmission parameter. It reproduces the numerical simulations reported in the paper, including time-series dynamics of outputs, profits, welfare and the endogenous tax rate, bifurcation diagrams with respect to the transmission parameter, and chaos diagnostics based on the 0–1 test. It also generates the shock experiments (demand-intercept shocks), including firm-exit/persistence outcomes across shock magnitudes and timing. The package includes the main scripts and a README with instructions to run the code and reproduce figures/tables.
