“…Monte Carlo simulations are conducted under 112 different settings, each repeated 5,000 times, and the results of the simulations show that MIRDDs perform well in terms of bias, root mean squared error, coverage, and interval length in comparison with the standard RDD method. Also, additional simulations exhibit promising results compared to the state-of-theart RDD methods by Calonico, Cattaneo, and Titiunik (2014) and Branson et al (2019).…”
