Recent studies of cartel operation show that in most cartels both sales and price data were private information, and side payments between firms were used in addition to price wars to enforce collusion. This paper proposes a simple mechanism for collusion enforcement that incorporates these features. The mechanism applies to both price and quantity competition, and it allows for multi-product f...

In this note, we show that the pull-back of a fibration by a formal map is formal. The fibration is required to be totally non-homologous to zero, and to be a formal map as well. We are here referring to the notion of formality in the setting of rational homotopy theory. This result extends a theorem of Vigué-Poirrier, [10], where it is proved that the fibre of such a fibration is a formal spac...

Abstract Conventional and hybrid light quark baryons are constructed in the non-relativistic flux-tube model of Isgur and Paton, which is motivated by lattice QCD. The motion of the flux tube with the three quark positions fixed, except for center of mass corrections, is discussed. It is shown that the problem can be reduced to the independent motion of the junction and the strings connecting t...

‡ The George Washington University, MS 335, NASA Langley Research Center, Hampton, VA, 23681. ABSTRACT The dual-pump coherent anti-Stokes Raman spectroscopy (CARS) method is used to measure temperature and the relative species densities of N2, O2 and H2 in two experiments. Average values and rootmean-square (RMS) deviations are determined. Mean temperature measurements in a furnace containing a...
