We identify and quantify the effect of food tastes on international trade flows. Based a novel data set including all ingredients in national dishes 171 countries, we construct measure for similarity between countries. bilateral flows by exploiting that migrants’ differ from their host country. Our results show migration decreases more similar are migrant’s country origin her Thus, can do matte...

To identify and classify musical tastes, researchers have extensively relied on the use of music-genre labels. However, validity reliability such a method remain unclear. In this study, we examined extent to which 873 high school students felt able assess their tastes based Participants were expressly asked evaluate usability Results showed that majority respondents uncomfortable with labels, m...

Umami taste is responsible for sensing monosodium glutamate, nucleotide enhancers, and other amino acids that are appetitive to vertebrates and is one of the five basic tastes that also include sour, salty, sweet, and bitter. To study how ecological factors, especially diets, impact the evolution of the umami taste, we examined the umami taste receptor gene Tas1r1 in a phylogenetically diverse ...

The taste of foods, in particular the palatability of these tastes, exerts a powerful influence on our feeding choices. Although the lateral hypothalamus (LH) has long been known to regulate feeding behavior, taste processing in LH remains relatively understudied. Here, we examined single-unit LH responses in rats subjected to a battery of taste stimuli that differed in both chemical compositio...

Ageing affects taste perception as shown in psychophysical studies, however, underlying structural and functional mechanisms of these changes are still largely unknown. To investigate the neurobiology of age-related differences associated with processing of basic tastes, we measured brain activation (i.e. fMRI-BOLD activity) during tasting of four increasing concentrations of sweet, sour, salty...

Molecular and behavioral studies have identified heterodimers of the T1R family as receptors for detecting the tastes of sweet (T1R2 + T1R3) and umami (T1R1 + T1R3). However, behavioral studies have reported conflicting findings with T1R3 knockout (KO) mice. One study showed a complete or nearly complete loss of preference for sweet and umami substances by KO mice, whereas KO mice in another st...

Multi-attribute auctions play a very important role in our economy: (i) they are widely used in industry procurement; (ii) many markets for services are organized in a form reminiscent of private multi-attribute auctions; (iii) recently many Internetbased markets adopted multi-attribute structure. Multi-attribute auctions differ from standard low price auctions in that (a) a buyer chooses a win...

This paper provides a novel method for identifying informed institutional trading. I argue that, given an information signal about a stock, an investor’s tastes for certain characteristics of that stock can influence his decision to trade on the information. Thus, trades which deviate from an investor’s tastes are more likely to reflect information. I test this hypothesis with respect to invest...
