  An event weighting method for simulating Bose-Einstein effects in hadronic
final states is presented. The weight for an event depends on the momentum
distribution of identical bosons in the event. By using a theoretically
motivated parametrisation allowing weights below as well as above unity, the
necessity of a weight-rescaling procedure is eliminated. A single parameter is
used to adjust the average event weight to unity. Once adjusted, the same value
of the parameter gives average event weights that are essentially independent
of energy, initial quark flavour, multiplicity and jet topology. The influence
of Bose-Estein correlations on various measurable quantities in W pair
production is found to be small. In particular, none of the scenarios
considered resulted in a W mass shift larger than 20 MeV.
