The rising disparity in the price of healthful foods: 2004–2008

Nutrient-dense foods that are associated with better health outcomes tend to cost more per kilocalorie (kcal) than do refined grains, sweets and fats. The price disparity between healthful and less healthful foods appears to be growing.This study demonstrates a new method for linking longitudinal retail price data with objective, nutrient-based ratings of the nutritional quality of foods and beverages. Retail prices for 378 foods and beverages were obtained from major supermarket chains in the Seattle, WA for 2004–2008. Nutritional quality was based on energy density (kcal/g) and two measures of nutrient density, calculated using the Naturally Nutrient Rich (NNR) score and the Nutrient Rich Foods index (NRF_9.3). Food prices were expressed as $/100 g edible portion and as $/1000 kcal. Foods were stratified by quintiles of energy and nutrient density for analyses.Both measures of nutrient density were negatively associated with energy density and positively associated with cost per 1000 kcal. The mean cost of foods in the top quintile of nutrient density was $27.20/1000 kcal and the 4-year price increase was 29.2%. Foods in the bottom quintile cost a mean of $3.32/1000 kcal and the 4-year price increase was 16.1%.There is a growing price disparity between nutrient-dense foods and less nutritious options. Cost may pose a barrier to the adoption of healthier diets and so limit the impact of dietary guidance. Nutrient profiling methods provide objective criteria for tracking retail prices of foods in relation to their nutritional quality and for guiding food and nutrition policy.     

Whose Crystal Ball to Choose? Individual Difference in the Generalizability of Concept Testing

The product development literature has identified several individual characteristics that could influence how subjects respond to new products in concept tests. Few of these characteristics have been thoroughly investigated. The purpose of this research is to examine whether a number of personality traits (1) do influence concept evaluation scores and (2) can be used to identify respondents who provide substantially higher‐quality data in concept testing and whether the answers to these questions change for major versus minor innovations. The data quality of the concept testing data is defined using the generalizability theory, which provides a decision‐specific G‐coefficient. Higher quality means a G‐coefficient closer to 1 for a particular managerial decision. A Web‐based study to concept test 10 appliance innovations on multiple occasions was conducted among 105 panelists from the Institute for Online Consumer Studies (IOCS). During the concept testing, respondents' innovativeness, change‐seeking tendency, and propensity to exert cognitive effort were also measured. The results showed that the respondent characteristics influence the mean evaluation of the concepts and the psychometric quality of the concept testing data: (1) there is a significant linear relationship between concept scores and all of the innovativeness scales and change‐seeking measures; (2) the effect of innovativeness on concept testing outcomes is even more substantial for major innovations than for minor innovations; (3) the study provides evidence that the quality of concept testing data provided by respondents varies substantially with their innovativeness, whereas the differences are more modest when scaling just minor innovations; (5) there are also strong effects on data quality for the Need to Evaluate scale used to capture cognitive effort characteristics; and (6) there is little effect of segmenting on social desirability on data quality. Managerially, the current results indicate that a product manager wanting to concept test a pool of appliance concepts can benefit from screening for the respondents who will provide higher‐quality concept testing data. For example, respondents who are high on domain‐specific innovativeness provide the highest‐quality concept testing data for both minor and major innovations. The effects of traits are stronger for major innovations, supporting the claim that subject selection is a more critical issue in concept testing of major innovations. Product managers can improve the quality of their concept testing data without an increase in cost by screening the subjects they use in concept testing.     

Long-Run Implications for Developing Countries of Joint Implementation of Greenhouse Gas Mitigation

Joint Implementation (JI) calls for cooperation between industrialized and developing countries in the mitigation of greenhouse gas (GHG) emissions. However, a major concern of potential host countries is that, if they utilize their low-cost options for JI now, they will be left with only high cost options in the future, thereby penalizing them at a time when they may be obligated to mitigate GHGs themselves. This paper formalizes this hypothesis by utilizing an optimal control framework analogous to the Hotelling model of non-renewable resource extraction. The results are that cumulative abatement effects can impose costs on the future, but that they can be offset by technological change, market power, or compensation.     

Price Dispersion Over the Business Cycle: Evidence from the Airline Industry

This study provides empirical evidence documenting how price dispersion moves with the business cycle in the airline industry. Performing a fixed‐effects panel analysis on seventeen years of data covering two business cycles, we find that price dispersion is highly pro‐cyclical. This effect is especially pronounced for legacy carriers relative to low‐cost carriers. We show that our empirical result is consistent with firms' implementing second‐degree price‐discrimination tactics.     

The knowledge problem,determinism, and <Emphasis Type="Italic">The Sensory Order</Emphasis>

The arguments presented in Hayek's The Sensory Order suggest that the mind/brain is a decentralized spontaneous order. The decentralized nature of decision-making and the central role of classification in perception, cognition, and action, are solutions to the knowledge problem that confronts the system. The nature of this decentralized complex system suggests that the ordering is deterministic and that free will in the sense of a decision-maker being able to stand outside the circle of cause and effect is an illusion. If determinism is correct, how can we hold individuals responsible for their actions? It is argued that the evolution of responsibility, blame and credit are the products of a second Hayekian spontaneous order. Responsibility and the allocation of credit and blame are part of an implicit social contract that facilitates cultural evolution, political freedom, and economic growth. It is responsibility, not the existence of free will, that makes freedom possible.     

The role of brand communications on front line service employee beliefs,behaviors, and performance

Frontline service employees often vary in their delivery of the brand promise, leaving service firms with less direct control on other stakeholders’ brand perceptions. Internal branding efforts have been suggested as a way to improve employee performance. With this in mind, we develop a two-process model based on identification and internalization theories to explain how internally disseminating brand-relevant information to frontline employees enhances performance. Using multi-source data from the employees, managers, and customers of a business-to-business firm in the hospitality industry, we find that providing brand-specific information directly to frontline employees increases their identification with the brand (as evidenced in perceptions of firm authenticity) and enhances their internalization of brand values. Additional results suggest that firms should make an extra effort to communicate brand-specific information to frontline employees if they desire brand-consistent performance that is observable to managers and customers alike.     

A model of liability dollarization and myopic governments

Abstract

Liability dollarization of the domestic banking system represents a source of vulnerability for emerging market countries. The root cause is a lack of faith in the domestic currency, which ultimately stems from the belief that the government will not follow policies that promote long-run currency stability. This paper presents a model in which government myopia determines the unofficial dollarization of bank credit. Specifically, myopic politicians will choose low interest rates to expand short-run output in order to get re-elected, but this choice has the long-run consequence of increasing dollar lending. Increased liability dollarization is shown to force the hand of future decision-makers into choosing fixed exchange rates because of the fear that large depreciations will destroy balance sheets. The results imply that institutional reforms are necessary to reverse liability dollarization.     

Talent responses to talent status awareness—Not a question of simple reciprocation

How to manage talent effectively is a key question in organisations. Yet we still know relatively little about talent's psychological reactions to their exclusive status. Based on psychological contract theory and research on status, this study analyses a sample of 321 employees identified as talent by their organisations, only some of whom were aware of their exclusive talent status. The results provide evidence that talent status awareness moderates the relationship between a range of employer inducements and talent obligations, such that it increases the importance of some inducements while diminishing that of others. The study contributes to the talent management literature by isolating specific effects of talent status awareness and calling into question extant evidence of its direct positive effects on talent attitudes. The findings also have implications for talent status communication, talent management, and future theorising of talent reactions to their exclusive status.     

Distortionary fiscal policy and monetary policy goals

We reconsider the role of an inflation conservative central banker in a setting with distortionary taxation. To do so, we assume monetary and fiscal policy are decided by independent authorities that do not abide to past commitments. If the two authorities make policy decisions simultaneously, inflation conservatism causes fiscal overspending. But if fiscal policy is determined before monetary policy, inflation conservatism imposes fiscal discipline. These results clarify that in our setting the value of inflation conservatism depends crucially on the timing of policy decisions.
