Price discrimination and rationing of low price customers can often be observed (viz. flight and theater tickets, sales of branded goods). We construct a monopoly model to explain this phenomenon. A firm has the option to charge a high price on a 'day 1', and a low price on a 'day 2', and ration...

In a general equilibrium macro model with wage bargaining, agents are divided into capitalists and workers. The markets for produced goods and money are competitive, but the wage rate is determined by negotiation between an employers' union and a trade union. Unions are supposed to be "long...

An overlapping generations, macro model where consumers are divided into workers and capitalists is analysed. In each period the wage rate is negotiated between an employers' union and a trade union. Other prices adjust competitively. The solution concept used is cooperative, the wage rate...

A multisectoral temporary general equilibrium macro model with wage bargaining is presented. In each sector agents are divided into capitalists and workers. The markets for produced goods and money are competitive, but the wage rate in a sector is determined by negotiation between an employers'...

Consider a labor market where the parties are able to write contracts contingent on the state of demand and productivity. If it is realistically assumed that the workers differ wrt. their reservation wages, then it becomes a natural presumption that firms on the market will offer several...

This paper investigates the effects on production and employment of an introduction of profit sharing in an economy initially stuck in unemployment. The economy considered is divided into many small production sectors. in each sector the wage rate is negotiated between an employers' union and a...
