This overcomes the problems faced by traditional demand analysis which neglects the influence of labour supply and thus assumes weak separability. The conditional approach allows for more exact tests of weak separability using more flexible functional forms than is possible when estimating an unconditional commodity demand–labour supply model. The impact of the conditioned demand responses and the relaxation of weak separability on measures of marginal tax reform is examined.736059 bytesapplication/pdfenPreliminary draft.
