We study Hotelling’s classic duopoly location model in continuous time with flow payoffs accumulated over time and the price dimension made explicit. In an experimental setting, subjects chose price and location in treatments varying only by the speed of adjustment. We find that the principle of minimum differentiation generally holds, with little distance between subjects’ location decisions. ...

We investigate experimentally the impact of continuous time on a four-player Hotelling location game. The static pure strategy Nash equilibrium (NE) consists of firms paired-up at the first and third quartiles of the linear city. In repeated simultaneous move games (discrete time grid), we fail to obtain convergence to this distinctive NE, as have previous studies. However, with asynchronous mo...

We consider the Hotelling-Downs model with n ≥ 2 office seeking candidates and runoff voting. We show that Nash equilibria in pure strategies always exist and that there are typically multiple equilibria, both convergent (all candidates are located at the median) and divergent (candidates locate at distinct positions), though only divergent equilibria are robust to free entry. Moreover, two-pol...

This article creates a general class of perturbation models which are described by an underlying null model that accounts for most of the structure in data while a perturbation accounts for possible small localized departures. The goal is to develop theory and inferential methods for fitting the perturbation models including the general case when the null model contains a set of nuisance parame...

We propose exact simulation-based procedures for: (i) testing mean-variance efficiency when the zero-beta rate is unknown; (ii) building confidence intervals for the zero-beta rate. On observing that this parameter may be weakly identified, we propose likelihood-ratio-type tests as well as Fieller-type procedures based on a Hotelling-HAC statistic, which are robust to weak identification and al...

The construction of the Guangdong-Hong Kong-Macao Greater Bay Area requires establishment a comprehensive port cooperation mechanism. Coordination is key to integration. This paper establishes multi-group Lotka-Volterra model based on theory competition and study evolution relationships among Hong Kong Port, Shenzhen Guangzhou Port. results show that three major ports have predator-prey roles f...

Evaluation of flat-panel angiography equipment through conventional image quality metrics is limited by the scope of standard spatial-domain image quality metric(s), such as contrast-to-noise ratio and spatial resolution, or by restricted access to appropriate data to calculate Fourier domain measurements, such as modulation transfer function, noise power spectrum, and detective quantum efficie...
