Revisiting The Quiet Life Hypothesis In The Indonesian Banking Industry, Samuel Sumartoyo, Chaikal Nuryakin

Bulletin of Monetary Economics and Banking

This study explores the Quiet Life Hypothesis (QLH) in different bank groups based on market-dominant and state ownership. The instrumental-variable regression results confirm the quiet life hypothesis at the industry level. At the group level, there is no different tendency to act quiet life between the dominant and non-dominant banks. On the other hand, the State-Owned Banks (SOBs) show a more potent act of quiet life than private banks. While the results for SOB were backed by theory and previous empirical studies, they raised the question of why the private banks conduct such “lazy” behavior.

Simulation Based Model For Canine Distemper Virus In Prey-Predator Dynamics, Mussa A. Stephano

Tanzania Journal of Science

This study investigates the dynamic interactions of a prey-predator ecosystem infected with Canine Distemper Virus (CDV), focusing on predation and disease transmission. A deterministic model, coupled with Monte Carlo simulations (MCS), employed to capture both stochastic variability and environmental fluctuations. The findings indicate that classical prey-predator cycles provide the baseline for population dynamics, but the introduction of CDV and environmental noise fundamentally alters system behavior. Initially, populations exhibit oscillations that gradually stabilize into dynamic equilibria. However, the disease persists within both prey and predator populations, suggesting endemicity rather than extinction. Predation plays a dual role in disease dynamics, while it …
