Analysis of the mechanism of injury in non-fatal vehicle-to-pedestrian and vehicle-to-bicyclist frontal crashes in Sweden

The aim of this paper is to analyse and compare injuries and injury sources in pedestrian and bicyclist non-fatal real-life frontal passengercar crashes, considering in what way pedestrian injury mitigation systems also might be adequate for bicyclists. Data from 203 non-fatal vehicle-to-pedestrian and vehicle-to-bicyclist crashes from 1997 through 2006 in a city in northern Sweden were analysed by use of the hospitals injury data base in addition to interviews with the injured. In vehicle-to-pedestrian crashes (n = 103) head and neck injuries were in general due to hitting the windscreen frame, while in vehicle-to-bicycle crashes (n = 100) head and neck injuries were typically sustained by ground impact. Abdominal, pelvic and thoracic injuries in pedestrians and thoracic injuries in bicyclists were in general caused by impacting the bonnet. In vehicle-to-pedestrian crashes, energy reducing airbags at critical impact points with low yielding ability on the car, as the bonnet and the windscreen frame, might reduce injuries. As vehicle-to-bicyclist crashes occurred mostly in good lighting conditions and visibility and the ground impact causing almost four times as many injuries as an impact to the different regions of the car, crash avoidance systems as well as separating bicyclists from motor traffic, may contribute to mitigate these injuries.     

The dynamics of optimal abatement strategies for multiple pollutants—An illustration in the Greenhouse

We investigate optimal abatement strategies for cumulative and interacting pollutants. We show that different decay rates can cause non-monotonic behavior in the optimal paths of emissions, the aggregate level of pollution, and even the relative optimal price for emissions. This contrasts strikingly with the case of a single pollutant. The results are illustrated by numerical simulations, first for instructive fictitious and second for more realistic parameters mimicking the greenhouse problem. The results add to the skepticism existing about whether the concept of global warming potential is a useful indicator for the optimal relative abatement of different GHGs over time. In fact, we show that a constant index suitable for comparing dynamically different pollutants with respect to their economic harmfulness does not exist.     

Protester or non‐protester: a binary state? On the use (and non‐use) of latent class models to analyse protesting in economic valuation*

In the analysis of stated preferences studies, it is often assumed that protesting is a discretely measured item only occurring among those who are not willing to pay. However, various studies have recently shown that protest beliefs are as well held by respondents who state a positive willingness to pay (WTP). Using latent class (LC) models, we investigate the extent of heterogeneity with respect to protest beliefs among all respondents of two contingent valuation studies. The advantage of LC models is that classes of individuals are endogenously identified and no selection bias is introduced by ad hoc definitions of protesters. Further we investigate whether it is possible to identify a class of non‐protesters. Finding a group of pure non‐protesters could indicate how strongly stated WTP in the whole sample is affected by protest beliefs. For both samples, we find a class with strong protest beliefs but no pure non‐protest class. Overall, our results suggest that LC models might not be the first choice to determine unbiased WTP measures, but they provide valuable insights into the degree of protesting expressed by different groups and corresponding determinants of group membership.     

Testing structural equation models: the impact of error variances in the data generating process

Yet another paper on fit measures? To our knowledge, very few papers discuss how fit measures are affected by error variance in the Data Generating Process (DGP). The present paper deals with this. Based upon an extensive simulation study, this paper shows that the effects of increased error variance differ significantly for various fit measures. In addition to error variance the effects depend on sample size and severity of misspecification. The findings confirm the general notion that good fit as measured by the chi-square, RMSEA and GFI etc. does not necessarily mean that the model is correctly specified and reliable. One finding is that the chi square test may give support to misspecified models in situations with a high level of error variance in the DGP, for small sample sizes. Another finding is that the chi-square test looses power also for large sample sizes when the model is negligible misspecified. Other results include incremental fit indices as NFI and RFI which prove to be more informative indicators under these circumstances. At the end of the paper we formulate some guidelines for use of different fit measures.     

The sky is the limit? The determinants and constraints of European airports commercial revenues

This study investigates the determinants of commercial and retail airport revenues from real estate operations. Aviation revenues per passenger are mainly determined by the national income per capita in the area where the airport is located, the percentage of leisure travelers and the size of the airport. Main drivers of commercial revenues per passenger include the number of passengers passing through the airport, the ratio of commercial to total revenues, national income, the share of domestic and leisure travelers and the number of flights. These results are in line with previous findings of a negative influence of business travelers on commercial revenues per passenger. We also find that a large amount of retail space per passenger is generally associated with lower commercial revenues per square meter confirming decreasing marginal revenue effects. Real estate revenues per passenger are positively associated with national income per capita at airport location, share of intra-EU passengers and percent delayed flights.     

Virtuousness and the Common Good as a Conceptual Framework for Harmonizing the Goals of the Individual,Organizations, and the Economy

Despite the expansion of the regulatory state, we continue to witness widespread unethical practices across society. This paper addresses these challenges of ethical failure, misalignment, and dissonance by developing a conceptual framework that provides an explicit basis for understanding virtuousness and the common good directed toward the goal of eudaimonia or human flourishing. While much of the literature on virtuousness has focused on the organization, this paper uses a more comprehensive understanding that also incorporates the agent and the economy examined through their relational order. The common good provides direction for guiding behavior of all the various stakeholders and the context for understanding virtuousness, while it is through virtuousness that the common good is effectively realized. Virtuousness and the common good are therefore in effect ‘two sides of the same coin.’ This paper develops a virtuousness–common good conceptual framework which explores the basis for harmonizing the goals of the individual, organization, and the economy.     

Creating and consuming experiences in retail store environments: Comparing retailer and consumer perspectives

This article investigates the substance of arguments about an experience-oriented economy and experience-seeking consumption in retailing. Employing a case study research approach (n=7) and the Critical Incident Technique (n=252), we show how retailers as well as consumers relate to in-store experiences. The results point out that retailers’ use ever more advanced techniques in order to create compelling in-store experiences to their consumers. In contrast, the depiction given by consumers reveals that their in-store experiences to a large extent are constituted by traditional values such as the behavior of the personnel, a satisfactory selection of products and a layout that facilitates the store visit.     

Transfer Pricing and Hold-Ups in Supply Chains

Abstract. We reconsider the hold‐up problem under symmetric information when more than two parties form a ‘supply chain’. The parties are assumed to renegotiate bilaterally and sequentially. Potential trade distortions then arise in addition to the usual investment problem. Following Edlin and Reichelstein (1995, 1996), we consider fixed‐quantity contracts. First‐best allocations are shown to be attainable if the parties are able to commit to a ‘forced‐compliance’ regime where a central office monitors the consistency of the bilateral renegotiations.
