There have been heated debates on the negative interest rate policy (NIRP) since it was first introduced in major economies. Critics argue that deposit interest rates cannot break through the zero lower bound (ZLB) and that banks' interest margins can be heavily squeezed under the NIRP. The...

In this paper, we consider dynamic panel data models where the autoregressive parameter changes over time. We propose the GMM and ML estimators for this model. We conduct Monte Carlo simulation to compare the performance of these two estimators. The simulation results show that the ML estimator...

Metal oxide nanoparticles (MONPs) with a large specific surface area are expected to bind with antibiotic resistance genes (ARGs), thereby controlling ARGs’ contamination by reducing their concentration and mobilization. Here, adsorption experiments were carried out and it was found that...
