Distribution and Growth in an Economy with Limited Needs: Variable Markups and ‘The End of Work’
构建了一个需求有限的经济模型，其中每种商品由垄断者拥有，工人可从事物质生产或知识创新。随着生产率提高，经济从工资随生产率增长的“索洛区域”转向工资反而下降的“马克思区域”。
This article studies a model of the distribution of income under bounded needs. Utility derived from any given is bounded from above and demand is therefore not isoelastic. On the other hand, introducing new varieties always increases utility. It is assumed that each variety is owned by a monopoly. Workers can specialise in material goods production or in the knowledge sector, which designs new varieties. As productivity increases, the economy moves from a 'Solovian zone' where wages increase with productivity, to a 'Marxian' zone where they paradoxically decline with productivity.
