Continuous Differentiation: Hotelling Revisits the Lab

چکیده

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 moves in continuous time treatments, the NE clearly emerges.

Stability in Competition? Hotelling in Continuous Time

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. ...

The 2D Hotelling filter - a quantitative noise-reducing principal-component filter for dynamic PET data, with applications in patient dose reduction

BACKGROUND In this paper we apply the principal-component analysis filter (Hotelling filter) to reduce noise from dynamic positron-emission tomography (PET) patient data, for a number of different radio-tracer molecules. We furthermore show how preprocessing images with this filter improves parametric images created from such dynamic sequence.We use zero-mean unit variance normalization, prior ...

Welfare losses in models of horizontal And vertical differentiation

We study the percentage of welfare losses (PWL) in models of horizontal and vertical differentiation. In the Hotelling model, we show that PWL depends on the underlying parameters in a non-monotonic way. We also show that PWL can be calculated from market data-locations and market size-except when the market is covered and exhibits maximal product differentiation. PWL can be very large-up to 37...

Maximal or Minimal Differentiation in a Hotelling Market? A Fresh Perspective

A perplexing problem in spatial modelling—going back to Hotelling’s linear market—is whether firms will cluster together or separate themselves. Maximal differentiation is the prevailing equilibrium when travel costs are quadratic and minimal differentiation results when price competition is limited. The reality for most markets is that the force that draws firms together (maximize demand) and ...

Bandwagon, underdog, and political competition: the uni-dimensional case

The present paper studies the Hotelling-Downs and the Wittman-Roemer models of two-party competition when voter conformism is present and the policy space is uni-dimensional. We consider two types of voter conformism, bandwagon and underdog, and study their effects on political equilibrium of the two models. Even if voter conformism is present, the Hotelling-Downs parties propose an identical p...
