Identifying the Degree of Collusion Under Proportional Reduction

Oleksandr Shcherbakov & Naoki Wakamori
Proportional reduction is a common cartel practice in which cartel members reduce their output proportionately. We develop a method to quantify this reduction relative to a benchmark market equilibrium scenario and relate the reduction to the traditional conduct parameter. Our measure is continuous, allowing us to have an intuitive interpretation as the “degree of collusion” and nesting the earlier models in the existing literature. Furthermore, our methodology addresses Corts’ (1999) critique by estimating time-varying degree...

A Possible Magnetic Structure of the Cluster-Based Haldane Compound Fedotovite K2Cu3O(SO4)3

Masashi Hase, Kirrily C. Rule, James R. Hester, Jaime A. Fernandez-Baca, Takatsugu Masuda & Yukari Matsuo
We carried out neutron powder diffraction experiments on the cluster-based Haldane compound fedotovite K2Cu3O(SO4)3. Weak magnetic reflections caused by a magnetic long-range order appeared below an antiferromagnetic transition temperature TN =3.1 K. We propose a possible magnetic structure that is consistent with the magnetic properties reported in the literature.

Monitoring of Methane Emissions at Southern Hydrate Ridge using Deep-Sea Cabled Observatory

Yann Marcon , Deborah Kelley , Blair Thornton , Dana Manalang & Gerhard Bohrmann
Natural methane gas release from the seafloor is a widespread phenomenon that occurs at cold seeps along most continental margins. Since their discovery in the early 1980s, seeps have been the focus of intensive research, partly aimed at refining the global carbon budget. However, deep-sea research is challenging and expensive and, to date, few programs have successfully monitored the variability of methane gas release over several weeks or more. Long-term monitoring is necessary to study...

Reduction of the Ordered Magnetic Moment by Quantum Fluctuation in the Antiferromagnetic Spin-5 2 Dimer Compound FeVMoO7

Masashi Hase, James R. Hester, Kirrily C. Rule, Vladimir Yu. Pomjakushin, Akira Matsuo & Koichi Kindo
We investigated the magnetism of FeVMoO7 by performing magnetization, specific heat, electron spin resonance, and neutron diffraction experiments. We observed an antiferromagnetically ordered state below T_N = 10.8 K. We consider that the probable spin model is an interacting antiferromagnetic spin-5/2 dimer model where spin dimers are connected by interdimer interactions. The intradimer interaction was evaluated to be J = 10.5 +- 0.5 K. The magnitude of ordered magnetic moments is 4.00(7) mu_B at 4...
