متن کاملValue, Scarcity, and Preference Polarization Value and the Perception of Scarcity Experiment 2: the Interaction of Value and Scarcity in Music Experiment 3: Polarization of Preferences for Paintings
It is well established that consumers infer value from scarcity, which Cialdini (1984) called the scarcity principle. We demonstrate the reverse of this effect of scarcity on perceived value – consumers infer scarcity of product supply from product attractiveness. We show that this effect arises from the operation of what we call “the value heuristic”. In addition, we show that the value heuris...

We find a significant and positive average increase in Tobin’s Q among the Massachusetts treated firms, suggesting that staggered boards can be beneficial for early-life-cycle firms, which exhibit greater information as...
