Uncertain Demand, Consumer Loss Aversion, and Flat-Rate Tariffs

The so called flat-rate bias is a well documented phenomenon caused by consumers' desire to be insured against fluctuations in their billing amounts. This paper shows that expectation-based loss aversion provides a formal explanation for this bias. We solve for the optimal two-part tariff when contracting with loss-averse consumers who are uncertain about their demand. The optimal tariff is a flat rate if marginal cost of production is low compared to a consumer's degree of loss aversion and if there is enough variation in the consumer's demand. Moreover, if consumers differ with respect to the degree of loss aversion, firms' optimal menu of tariffs typically comprises a flat-rate contract

On the Economics of Industrial Safety

Diabetic foot complications are associated with substantial costs and loss of quality of life. This article gives an overview of available and emerging devices for the monitoring of foot temperature as a means of early detection of foot disorders in diabetes. The aim is to describe the technologies and to summarize experiences from experimental use. Studies show that regular monitoring of foot temperature may limit the incidence of disabling conditions such as foot ulcers and lower-limb amputations. Infrared thermometry and liquid crystal thermography were identified as the leading technologies in use today. Both technologies are feasible for temperature monitoring of the feet and could be used as a complement to current practices for foot examinations in diabetes.Original Publication: Kerstin Roback, An overview of temperature monitoring devices for early detection of diabetic foot disorders, 2010, EXPERT REVIEW OF MEDICAL DEVICES, (7), 5, 711-718. http://dx.doi.org/10.1586/ERD.10.35 Copyright: Expert Reviews http://www.expert-reviews.com/</p

Pricing and Information Disclosure in Markets with Loss-Averse Consumers

Abstract: We develop a theory of imperfect competition with loss-averse consumers. All consumers are fully informed about match value and price at the time they make their purchasing decision. However, a share of consumers are initially uncertain about their tastes and form a reference point consisting of an expected match value and an expected price distribution, while other consumers are perfectly informed all the time. We derive pricing implications in duopoly with asymmetric ?rms. In particular, we show that a market may exhibit more price variation the larger the share of uninformed, loss-averse consumers. We also derive implications for ?rm strategy and public policy concerning ?rms’ incentives to inform consumers about their match value prior to forming their reference point

Modeling the Psychology of Consumer and Firm Behavior with Behavioral Economics

Marketing is an applied science that tries to explain and influence how firms and consumers actually behave in markets. Marketing models are usually applications of economic theories. These theories are general and produce precise predictions, but they rely on strong assumptions of rationality of consumers and firms. Theories based on rationality limits could prove similarly general and precise, while grounding theories in psychological plausibility and explaining facts which are puzzles for the standard approach. Behavioral economics explores the implications of limits of rationality. The goal is to make economic theories more plausible while maintaining formal power and accurate prediction of field data. This review focuses selectively on six types of models used in behavioral economics that can be applied to marketing. Three of the models generalize consumer preference to allow (1) sensitivity to reference points (and loss-aversion); (2) social preferences toward outcomes of others; and (3) preference for instant gratification (quasi-hyperbolic discounting). The three models are applied to industrial channel bargaining, salesforce compensation, and pricing of virtuous goods such as gym memberships. The other three models generalize the concept of gametheoretic equilibrium, allowing decision makers to make mistakes (quantal response equilibrium), encounter limits on the depth of strategic thinking (cognitive hierarchy), and equilibrate by learning from feedback (self-tuning EWA). These are applied to marketing strategy problems involving differentiated products, competitive entry into large and small markets, and low-price guarantees. The main goal of this selected review is to encourage marketing researchers of all kinds to apply these tools to marketing. Understanding the models and applying them is a technical challenge for marketing modelers, which also requires thoughtful input from psychologists studying details of consumer behavior. As a result, models like these could create a common language for modelers who prize formality and psychologists who prize realism

Information as a Substitute for Bailouts in Sovereign Debt Markets

This paper argues that multilateral financial institutions (MFIs), such as the International Monetary Fund, play an important informational role in international financial markets. By providing low-cost and high quality information, that is otherwise very costly for private lenders to obtain, the MFI allows a private lender to form a more accurate estimate of the credit-worthiness of a sovereign borrower. This creates a positive externality for private lenders and for sovereign borrowers with low risk credit ratings that are revealed by the provision of MFI information. The MFI can choose to internalize the negative externality created for sovereign borrowers who are revealed to be a higher credit risk by providing stand-by commitments to the sovereign. We construct a formal model of the private lenders decision to purchase costly information about the sovereign borrower. The model suggests that the free provision of MFI information has greater positive effects on financial markets the less risk-averse the private lender, the less information the private lender already has, the greater the size of the loan, and the smaller the expected default probability of the sovereign borrower.information default bailouts IMF

Deterrence of a criminal team: how to rely on its members' shortcomings?

In this paper, we modelize a criminal organization as an agency where the Principal and the Agent have different sensibilities towards the risk of arrestation and punishment, and at the same time have different skills with respect to general organization tasks, crime realization or detection avoidance activities (i.e. allowing to reduce the probability of detection). In this set up, we first compare two regimes of exclusive sanctions (either the sanctions are borne by the Principal/beneficiary of the crime, or they are borne by the Agent/perpetrator of the crime), and we analyze the comparative efficiency of the various instruments which are at the disposal of public authorities to prevent corporation in criminal activities (frequency of control and level of monetary penalties). Finally, we study a case with joint liability.Criminal teams, corporate criminality, state dependent risk aversion, deterrence, monetary penalties versus detection

Sick Pay Provision in Experimental Labor Markets

Sick pay is a common provision in most labor contracts. This paper employs an experimental gift-exchange environment to explore two related questions using both managers and undergraduates as subjects. First, do workers reciprocate sick pay in the same way as they reciprocate wage payments? Second, do firms benefit from offering sick pay? Firms may benefit in two different ways: directly, from workers reciprocating higher sick pay with higher efforts; and indirectly, from self-selection of reciprocal workers into contracts with higher sick pay. Our main finding is that the direct effect is rather weak in terms of effort and negative in terms of profits. However, when there is competition among firms for workers, sick pay can become an important advantage. Consequently, competition leads to a higher provision of sick pay relative to a monopsonistic labor market.
