We study markets for sensitive personal information. An agent wants to communicate with another party but any revealed information can be intercepted and sold to a third party whose reaction harms the agent. The market for information induces an adverse sorting effect, allocating the information...

Testing for and measuring habitual brand loyalty (HBL) is one of the classic questions in quantitative marketing. We propose a nonparametric test for HBL using a ``dynamic potential outcomes'' model that resolves the classic identification challenge of decoupling state dependence and unobserved...

We study habitual brand loyalty, one of the earliest empirically-studied forms of switching costs and a classic source of structural state-dependence in consumer demand. Auxiliary instruments and economically-motivated restrictions can tighten nonparametric bounds on the extent of brand loyalty...

We discover that letting agents pairwise sequentially exchange at "wrong" prices has a robust effect on prices at convergence. If the initial relative price for a good is cheaper than the equilibrium walrasian price due to initial endowments, the initial excess demand effect pushes resource...

We present a novel approach to finite Rational Inattention (RI) models based on the ignorance equivalent, a fictitious action with state-dependent payoffs that effectively summarizes the optimal learning and conditional choices. The ignorance equivalent allows us to recast the RI problem as a...

The traditional information paradigm postulates that increasing the amount of information and establishing full transparency helps consumers with their decisions. We challenge this assumption and address criteria that good consumer information needs to fulfil. Based on the findings from research...

We study the consumption and investment model under time-varying liquidity constraints (TVLC) that are widely used in reality. We first develop a martingale method to analyze the case in which the borrowing limit is specified by the debt-to-income ratio limit and then extend this framework to...

Can stock price movements be traced back partially to interpersonal utility effects? That is, are shareholders also chasing nonfinancial goals apart from generating profit under risk that can be ascribed neither to findings of behavioral finance nor to traditional economical theories? Inspired...

In "Marketing Information: A Competitive Analysis,'' Sarvary and Parker (1997) (S&P) [Marketing Science, 16(1): 24-38] argue that, a reduction in the price of one information product can lead to an increase in demand for another information product -- information products can be gross...
