workers supplied regardless of the wage). Suppose there are two perfectly competitive industries/sectors with labour demand Da=107−Wa in sector A and labour demand Db=97−Wb in sector B. 1. On separate graphs, labour demand in sector A, labour demand in sector B. and vertical intercept . Aggregate supply and demand are equal when 3. Since both sectors have wage W there will be workers demanded in sector A and workers demanded in sector B. This answer must be workers will find a job in sector A, workers will find a job in sector B and workers will be unemployed.
