Several types of constraints must be satisfied by schedules of real world sports leagues, e. g. stadium unavailability … constraints are considered as 'soft' ones. There are various models appropriately describing the environment of real sport leagues … here a model which satisfies the demands of many sports leagues. We solve our model by a method which consists in …

Empirical evidence reveals that unemployment tends to increase property crime but that it has no effect on violent … crime. To explain these facts, we examine a model of criminal gangs and suggest that there is a substitution effect between … property crime and violent crime at work. In the model, non-monetary valuation of gang membership is private knowledge. Thus …
