Question：Which of the following is an example of cyclical unemployment?
　　A.The entry of school leavers into the labour pool each year
　　B.Lay-offs among agricultural labourers in winter
　　C.Automation of ticketing services in tourism
　　D.Recession in the building industry
　　Answer：D
        Rationale: Recession is part of the business cycle: demand for output and jobs falls, and unemployment rises until recovery is well under way. Option A is an example of frictional unemployment; option B of seasonal unemployment; option C of technological unemployment.
　　Pitfalls: It is easy to confuse cyclical with seasonal unemployment, or frictional unemployment that occurs on a seasonal basis (eg option A). You need to associate cyclical employment firmly with business cycles.
