Abstract	The two primary approaches to estimate marginal willingness-to-pay (MWTP) are hedonic (Rosen, 1974) and discrete choice models (McFadden, 1974). This paper provides a tractable framework to investigate the relationship between MWTP in these models. By deriving the hedonic price gradient implicitly from the share function in the discrete choice model, I present an analytical mapping between the hedonic gradient (hence, the hedonic MWTP) and choice probabilities in the discrete choice model. Intuitively, the hedonic MWTP depends on weighted averages of marginal utilities where higher weights are assigned to individuals whose choice probabilities indicate more uncertain choices (marginal individuals). As this choice becomes more certain, the weights start to decrease. Since the hedonic method relies on tangencies between indifference curves and the hedonic price function to identify MWTP, inframarginal individuals (whose bid functions are not tangent to the hedonic price function) have low weights (they have choice probabilities that are close to 0 or 1 and low choice variances). This novel analytical mapping between the hedonic gradient and the share function can be used to identify conditions when MWTP in the two models are similar.
