Left and right handedness of fermions and bosons
It is shown, by using Grassmann space to describe the internal degrees of
freedom of fermions and bosons, that the Weyl like equation exists not only for
massless fermions but also for massless gauge bosons. The corresponding states
have well defined helicity and handedness. It is shown that spinors and gauge
bosons of the same handedness only interact.Comment: 18 pages, LaTeX, no figures, typographical errors corrected and a few

The structure of the quantum mechanical state space and induced superselection rules
The role of superselection rules for the derivation of classical probability
within quantum mechanics is investigated and examples of superselection rules
induced by the environment are discussed.Comment: 11 pages, Standard Latex 2.0

Multinational Learning under Asymmetric Information
The aim of this paper is to analyze the competition between a multinational and the incumbent firm in a foreign market under asymmetric information about demand and unobservable outputs. It is shown that the incumbent firm increases its production in the first period to signal to the multinational that the demand is low. The multinational reduces its output in the foreign market in order to signal-jam. In addition, the multinational increases its production in the other market. However, total production of the multinational is lower. Implications for research and development expenditure by the multinational are examined
The Pauli Equation for Probability Distributions
The "marginal" distributions for measurable coordinate and spin projection is
introduced. Then, the analog of the Pauli equation for spin-1/2 particle is
obtained for such probability distributions instead of the usual wave
functions. That allows a classical-like approach to quantum mechanics. Some
illuminating examples are presented.Comment: 14 pages, ReVTe
