Available in PDF, EPUB and Kindle. Book excerpt: This dissertation consists of three independent but related papers. All of them are devoted to estimate demand functions in presence of unobservable product attributes, such as quality, using different identification strategies. The first two exercises are based on a discrete choice model using the product-market approach developed by Berry (1994) with aggregate data information for gum and beer consumption. The third paper uses a control function approach as an identification strategy in order to estimate the choice model using disaggregated (micro level) data on household choices. These exercises reveal the importance of controlling for price endogeneity due to the existence of unobservable product attributes incorporating substantial bias in the coefficients when ignored.
