ABSTRACT
Several objections to the market clearing approach to unemployment have already been raised in chapter four. In this chapter we will explore some alternative approaches to non-natural unemployment which rely upon the notion that market disequilibrium is not only the normal state of affairs but also that correcting forces may be so weak or even non-existent that non-natural unemployment persists over a sufficiently long period for it to be a matter of concern to policymakers. Initially we consider the traditional Keynesian approach to unemployment but later in this chapter more recent disequilibrium analysis is examined.
