The paired comparison (PC) method is used to investigate reliability, transitivity, and decision time for binary choices among goods and sums of money. The PC method reveals inconsistent choices and yields individual preference order over the set of items being compared. The data reported support the transitivity assumption and demonstrate high reliability for individual preference order. The p...

We consider a market in which sellers can exert an informationgathering effort to advise buyers about which of two goods best fits their needs. Sellers may steer buyers towards the higher margin good. We show that for sellers to collect and reveal information, profits on both goods must be sufficiently close to each other, i.e., lie within an implementability cone, which competition or regulati...

Household scale economies are plausibly attributed to shared household public goods that make larger households better off at the same level of per capita resources. Larger households should therefore have higher per capita consumption of private goods, such as food, provided that they do not substitute too much toward the effectively cheaper public goods. The evidence shows exactly the opposit...

We measure the causal effects of income and wealth on the demand for private-label products. Prior research suggests that these effects are large and, in particular, that private-label demand rises during recessions. Our empirical analysis is based on a comprehensive household-level transactions database matched with price information from store-level scanner data and wealth data based on local...

I study the optimal regulation of a …rm producing two goods. The …rm has private information about its cost of producing either of the goods. I explore the ways in which the optimal allocation di¤ers from its one dimensional counterpart. With binding constraints in both dimensions, the allocation involves distortions for the most e¢ cient producers and features overproduction for some less e¢ c...

The Tiebout hypothesis (residential choice depends solely on local public goods) is extensively applied to explain geographic segregation, and the related literature finds that residents are segregated according to their heterogeneous preferences for public goods. This paper further examines the heterogeneous preferences for private goods in a spatial economy without public goods. Specifically,...

MULTIPLE KERNEL AND MULTI-LABEL LEARNING FOR IMAGE CATEGORIZATION By Serhat Selçuk Bucak One crucial step in recovering useful information from large image collections is image categorization. The goal of image categorization is to find the relevant labels for a given image from a closed set of labels. Despite the huge interest and significant contributions by the research community, there rema...

W develop a framework for the optimal bundling problem of a multiproduct monopolist, who provides goods to consumers with private valuations that are random draws from a distribution with heavy tails. We show that in the Vickrey auction setting, the buyers prefer separate provision of the goods to any bundles. We also provide a complete characterization of the optimal bundling strategies for a ...
