Simulation results for concurrent change-change analysis with varying degrees of violation of the strict exogeneity assumption or the common trend assumption. Parameter \(\rho\) indicates the effect of the past outcome on the current outcome, thus representing the extent of violation of the strict exogeneity assumption. Parameter \(\omega\) indicates the effect of unobserved time-varying confounding, thus representing the extent of violation of the common trend assumption. The black dashed line represents the true causal effect of exposure on outcome
