Why Not Call a Margin Squeeze a Margin Squeeze?

The Economics of Margin Squeeze∗

The paper discusses economic theories of harm for anti-competitive margin squeeze by unregulated and regulated vertically integrated firms. We review both predation and foreclosure theories, as well as the mere exploitation of upstream market power. We show that foreclosure provides an appropriate framework in the case of an unregulated firm, whereas a firm under tight wholesale regulation shou...

Margin squeeze in fixed - network telephony markets : competitive or anticompetitive ?

How to squeeze a lexicon

Minimal acyclic deterministic finite automata (ADFAs) can be used as a compact representation of finite string sets with fast access time. Creating them with traditional algorithms of DFA minimization is a resource hog when a large collection of strings is involved. This paper aims to popularize an efficient but little known algorithm for creating minimal ADFAs recognizing a finite language, in...

Why the marriage squeeze cannot cause dowry inflation

It has been argued that rising dowry payments are caused by population growth. According to that explanation, termed the `marriage squeeze', a population increase leads to an excess supply of brides since men marry younger women. As a result, dowry payments rise in order to clear the marriage market. The explanation is essentially static; unmarried brides do not re-enter the marriage market. Th...

Two Different Squeeze Transformations

Lorentz boosts are squeeze transformations. While these transformations are similar to those in squeezed states of light, they are fundamentally different from both physical and mathematical points of view. The difference is illustrated in terms of two coupled harmonic oscillators, and in terms of the covariant harmonic oscillator formalism. The word “squeezed state” is relatively new and was d...
