Consumer psychology faces serious issues of internal and external relevance. Most of these issues originate in seven fundamental problems with the way consumer psychologists plan and conduct their research that could be called the seven sins of consumer psychology.
Markets for information products exhibit varying degrees of competition on both the supply and the demand side. This paper studies the potential complementarity of information products, equilibrium information buying behaviors and information price setting in such markets. Our game-theoretic model consists of two information providers selling imperfect information to two competing clients and allows for different information quality levels as well as varying degrees of client competition.
We track the evolution of financing of residential real estate through the housing boom in the early- to mid-2000s and the resolution of distress during the bust during the late 2000s. Financial innovation, in the form of non-traditional mortgage products and the expansion of alternative lending channels, namely non-agency securitization, fundamentally altered the mortgage landscape during the boom. We describe the impact of these changes in mortgage finance on borrowers and loan performance, as well as their impact on the resolution of distressed mortgages.
We posit that compared to the cognitive system, the affective system of judgment and decision making is relatively more engaged in the present. Specifically, we hypothesize that even if their accessibility is held constant, affective feelings are weighted more heavily in consumer judgments and decisions set in the present than in equivalent judgments and decisions set in the future or in the past.
Systemic risk is an issue of great concern in modern financial markets as well as, more broadly, in the management of complex systems. We propose an axiomatic framework for systemic risk. Our framework allows for an independent specification of (1) a functional of the cross-sectional profile of outcomes across agents in the system in a single scenario of nature, and (2) a functional of the profile of aggregated outcomes across scenarios of nature.
This paper formally analyzes the biases related to self-reporting in hedge fund databases by matching the quarterly equity holdings of a complete list of 13F-filing hedge fund companies to the union of five major commercial databases of self-reporting hedge funds between 1980 and 2008. We find that funds initiate self-reporting after positive abnormal returns that do not persist into the reporting period. Termination of self-reporting is followed by both return deterioration and outflows from the funds.
We consider a repeated newsvendor problem in which the decision-maker (DM) does not have access to the underlying distribution of discrete demand. We analyze three informational settings: i) the DM observes realized demand in each period; ii) the DM only observes realized sales; and iii) the DM observes realized sales but also a lost sales indicator that records whether demand was censored or not. We analyze the implications of censoring on performance and key characteristics that effective policies should possess.
As firms increasingly seek out consumers' ideas in various domains, they will encounter individuals with different levels of domain-specific knowledge. While both low- and high-knowledge consumers may be willing to share their ideas benevolently, the performance of the former is likely to be hindered by their lack of relevant knowledge in the problem domain. It is also well established that, despite their abundant knowledge, high-knowledge consumers may not perform in accordance with their full potential (due to factors such as shallow processing and inattention).
