Emulation funds are a potentially cost-effective way for multi-manager funds to improve their investment performance by delaying and netting trade signals from underlying managers. We develop a model to represent the expected sources of differential performance in an emulation fund relative to...

An emulation fund is designed to reduce trading activity, thereby lowering costs, for a multi-manager fund. It does this by delaying, and potentially combining, trading decisions from each employed fund manager to eliminate offsetting trades (e.g. one manager may buy a stock for her fund while...

Media-aware stock performance has been a hot issue in asset pricing. Numerous studies have focused on the impact of news content. However, few studies have paid attention to the form of news releases. In this paper, using data from 126,784 news of Chinese listed companies from 2013-2018, we...

This paper presents the analysis and design optimization of a coaxial surface-mounted permanent-magnet magnetic gear. The magnetic field distribution in the coaxial magnetic gear is calculated analytically in the polar coordinate system and then validated by the finite element method (FEM). The...

This study presents the auxiliary damping control with the reactive power loop on the rotor-side converter of doubly-fed induction generator (DFIG)-based wind farms to depress the sub-synchronous resonance oscillations in nearby turbogenerators. These generators are connected to a series...

Grid-connected wind turbines are fluctuating power sources that may produce flicker during continuous operation. This paper presents a simulation model of a MW-level variable speed wind turbine with a full-scale back-to-back power converter and permanent magnet synchronous generator (PMSG)...

This paper describes a frequency domain approach for evaluating the impact of tower shadow and wind shear effects (TSWS) on tie-line power oscillations. A simplified frequency domain model of an interconnected power system with a wind farm is developed. The transfer function, which relates the...

This paper provides the first systemic study of China’s policy and legal responses to security-related actions and disputes in the international trade regime. It starts with a brief review of the law and practices relating to the security exceptions under the World Trade Organization to...

We examine potential sources of measurement error when evaluating the after-tax performance of fund managers based on periodic snapshots of their holdings alone, compared to when daily transactions data are also available. To do this, we compare portfolio return estimates based on imputed trades...
