Options and sunspots in a simple monetary economy

Summary. We study sunspot immunity in a dynamic monetary economy in which consumers are allowed to trade put and call option contracts on the general price level. We define the concept of strong sunspot immunity to characterize economies that have no sunspot equilibria regardless of the number of extrinsic states and their probabilities of occurrence. We show that a small number of option contracts can make an economy strongly sunspot immune. In addition, we demonstrate how asset re-trading opportunities, and the associated capital gains and losses, reduce the number of options needed for this result to obtain.

On Sharing NATO Defence Burdens in the 1990s and Beyond

This article investigates NATO burden sharing in the 1990s in light of strategic, technological, political and membership changes. Both an ability‐to‐pay and a benefits‐received analysis of burden sharing are conducted. During 1990–99, there is no evidence of disproportionate burden sharing, where the large allies shoulder the burdens of the small. Nevertheless, the theoretical model predicts that this disproportionality will plague NATO in the near future. Thus far, there is still a significant concordance between benefits received and defence burdens carried. When alternative expansion scenarios are studied, the extent of disproportionality of burden sharing increases as NATO grows in size. A broader security burden‐sharing measure is devised and tested; based on this broader measure, there is still no disproportionality evident in the recent past.     

Gender and ethnic differences in factors that influence food intake

Abstract The objective of this research was to ascertain the gender-and ethnic-related factors that influence what one eats. This survey was conducted using a validated, pilot-tested questionnaire in 11 states and the District of Columbia, which were participating in the W-182 Western Regional Research project. The results indicated that the factors that influence what one eats differ by gender and ethnicity. Men were very much influenced by likes and dislikes, and by their spouse or significant other. Women were influenced by likes and dislikes, and health. Food likes/dislikes and concerns about health and weight were among the leading four factors for all ethnic groups. Food likes/dislikes were the top factor influencing what is eaten by 51% or more of Asians, Pacific Islanders, Caucasians and Hispanics. Concern about health was the top factor for 62% and 58%, respectively, of African Americans and Native Americans.     

All–Pay Auctions with Variable Rewards

We study all–pay auctions with variable rewards under incomplete information. In standard models, a reward depends on a bidder's privately known type; however, in our model it is also a function of his bid. We show that in such models there is a potential for paradoxical behavior where a reduction in the rewards or an increase in costs may increase the expected sum of bids or alternatively the expected highest bid.     

Do they Know it’s CSR at all? An Exploration of Socially Responsible Music Consumption

Porter and Kramer (Harv Bus Rev 84(12):78–92, 2006; Harv Bus Rev 89(1/2), 62–77, 2011) introduced ‘shared value’ as a ‘new conception of capitalism,’ claiming it is a powerful driver of economic growth and reconciliation between business and society. The idea has generated strong interest in business and academia; however, its theoretical precepts have not been rigorously assessed. In this paper, we provide a systematic and thorough analysis of shared value, focusing on its ontological and epistemological properties. Our review highlights that ‘shared value’ has spread into the language of multiple disciplines, but that its current conceptualization is vague, and it presents important discrepancies in the way it is defined and operationalized, such that it is more of a buzzword than a substantive concept. It also overlaps with many other (related) concepts and lacks empirical grounding. We offer recommendations for defining and measuring the concept, take a step toward disentangling it from related concepts, and identify relevant theories and research methods that would facilitate extending the knowledge frontier on shared value.
