Pricing dynamics in US fresh produce channels: new empirical evidence

Despite many valuable contributions, prior research has not completely explained retail pricing behavior. This study employs scanner data for 36 fresh produce items analyzing the relationship between costs of goods sold and retail prices to provide further insight into retail pricing behavior. Implications include: (1) where ‘natural’ variation in produce prices do not already exist from the supplier, retailers appear to introduce the variation themselves, independent from shipping point price; and (2) to the extent that supplier-retailer contracts for fresh produce develop, the resulting stabilizing influence on costs may have the preserve effect of increasing retail price variability to consumers.     

A Documentary Theory of States and Their Existence as Quasi-Abstract Entities

This article is concerned with the existence of states as a matter of fact, and it approaches that subject within the context of the ontology of social reality as a whole. It argues, first, that states do not have a place in the traditional Platonist duality of the concrete and the abstract. Second, that states belong to a third category – the quasi-abstract – that has received philosophical attention with a recently emerging theory of documentality. Documentality, derived from Austin’s theory of performative utterances, claims that documents acts can bring quasi-abstract objects, such as states into being. Third and finally, it argues that the existence of quasi-abstract states should not be rejected on the basis of the Principle of Parsimony, because geopolitical theories that recognise the existence of quasi-abstract states will have greater explanatory power than theories that deny their existence.     

Taking,giving, and impure altruism in dictator games

We show that, if giving is equivalent to not taking, impure altruism could account for List’s (in Journal of Political Economy 115(3):482–493, 2007) finding that the payoff to recipients in a dictator game decreases when the dictator has the option to take. We examine behavior in dictator games with different taking options but equivalent final payoff possibilities. We find that recipients tend to earn more as the amount the dictator must take to achieve a given final payoff increases, a result consistent with the hypothesis that the cold prickle of taking is stronger than the warm glow of giving. We conclude that not taking is not equivalent to giving and agree with List (in Journal of Political Economy 115(3):482–493, 2007) that the current social preference models fail to rationalize the observed data.     

Cheating to win: Dishonesty and the intensity of competition

We argue that the intensity of competition within a group or organization can have an important influence on whether or not people cheat. To make this point we first work through a simple model of strategic misreporting in the workplace. For low and high levels of competition we show that, in equilibrium, few are predicted to misreport. It is for medium levels of competition that misreporting is predicted to be highest. We test this prediction experimentally and find good support for it. This finding has implications for the design of incentive structures within groups and organizations.     

The Idealized Electoral College voting mechanism and shareholder power

Increasing concern over corporate governance has led to calls for more shareholder influence over corporate decisions, but allowing shareholders to vote on more issues may not affect the quality of governance. We should expect instead that, under current rules, shareholder voting will implement the preferences of the majority of large shareholders and management. This is because majority rule offers little incentive for small shareholders to vote. I offer a potential remedy in the form of a new voting rule, the Idealized Electoral College (IEC), modeled on the American Electoral College, that significantly increases the expected impact that a given shareholder has on election. The benefit of the mechanism is that it induces greater turnout, but the cost is that it sometimes assigns a winner that is not preferred by a majority of voters. Therefore, for issues on which management and small shareholders are likely to disagree, the IEC is superior to majority rule.     

On the County-Level Credit Outcome Beta

In their pioneering work, Musto and Souleles (Journal of Monetary Economics 53(1):59–84, 2006) apply portfolio theory to consumer lending. This paper extends their work by analyzing three county-level credit outcome betas. We use the probability of default calibrated from the credit score, the actual default rate, and the actual bankruptcy rate to compute ‘score’, ‘default’, and ‘bankruptcy’ betas for each U.S. county. The correlation between default and bankruptcy betas is quite low. Counties in states in which a borrower has a right to take action against aggressive collection practices tend to have higher default betas but lower bankruptcy betas. These findings suggest the possibility of an ‘informal bankruptcy’ option for consumers. The effects of county score, default, and bankruptcy betas on the county average revolving credit line per borrower are negative. For small lenders that do not have access to the detailed historical credit files on individual consumers, the county-level beta approach of this paper might be helpful for diversifying portfolios geographically and managing risk on existing accounts.     

Establishing Maintenance Resource Levels Using Selective Maintenance

We address the performance of a repairable system that is required to perform a sequence of equally spaced, identical missions with breaks between missions. The system is series-parallel in structure, and component repair can only be performed during breaks between missions. Due to limitations on maintenance resources, it may be impossible to make all necessary repairs before the next mission. Such situations require the use of selective maintenance, the process of identifying the subset of maintenance actions to perform from a set of desirable maintenance actions. We build upon previous research in selective maintenance by addressing decisions related to establishing capacities for the limited maintenance resources. We model mission-to-mission changes in maintenance resource capacity, and we develop a methodology for establishing constant resource capacities for a sequence of missions. Finally, we develop a methodology for integrating redundancy allocation and maintenance resource allocation decisions.     

Analyzing the volume and nature of emergency medical calls during severe weather events using regression methodologies

An effective emergency medical service (EMS) response to emergency medical calls during extreme weather events is a critical public service. Nearly all models for allocating EMS resources focus on normal operating conditions. However, public health risks become even more critical during extreme weather events, and hence, EMS systems must consider additional needs that arise during weather events to effectively respond to and treat patients. This paper seeks to characterize how the volume and nature of EMS calls are affected during extreme weather events with a particular focus on emergency preparedness. In contrast to other studies on disaster relief, where the focus is on delivery of temporary commodities, we focus on the delivery of routine emergency services during blizzards and hurricane evacuations. The dependence of emergency service quality on weather conditions is explored through a case study using real-world data from Hanover County, Virginia. The results suggest that whether it is snowing is significant in nearly all of the regression models. Variables associated with increased highway congestion, which become important during hurricane evacuations, are positively correlated with an increased call volume and the likelihood of high-risk calls. The analysis can aid public safety leaders in preparing for extreme weather events.
