No Vehicle Means No Aid—A Paradigm Change for the Humanitarian Logistics Business Model

The growing interest in humanitarian logistics is witnessed by an increasing focus of researchers and practitioners on that topic. Transportation in particular is emphasized as key to disaster relief. Despite its relevance, it suffers from a number of drawbacks, creating inefficiencies and limited effectiveness of aid. This article describes a paradigm change for fleet management in humanitarian organizations based on access‐based consumption. It further evaluates a case study among small‐scale producers in rural India, showing their acceptance for sharing vehicles. The newly created business opportunities will increase income and contribute to poverty alleviation. Taking part in the proposed vehicle‐sharing system can release them from ownership responsibilities and increase vehicle utilization, as well as improve vehicle availability, increasing the speed of aid from the perspective of humanitarian organizations. This article highlights the applicability of business models relying on the idea of access‐based consumption to not‐yet‐considered research fields, especially the transfer to rural areas of developing countries. © 2015 Wiley Periodicals, Inc.     

Common political culture: Evidence on regional corruption contagion

Although there are indications of common regional corruption characteristics, empirical studies of corruption have assumed that influences on corruption are country-specific. In this paper we report evidence based on a cross-section of 123 economies confirming that, with few specific exceptions, corruption is a regional phenomenon. Institutional change that reduces corruption in one country affects, therefore, neighboring countries.     

How to Coordinate Value Generation in Service Networks

The fundamental paradigm shift from traditional value chains to agile service value networks implies new economic and organizational challenges. As coordination mechanisms, auctions have proven to perform quite well in situations where intangible and heterogeneous goods are traded. Nevertheless, traditional approaches in the area of multidimensional combinatorial auctions are not quite suitable to enable the trade of composite services. A flawless service execution and therefore the requester’s valuation highly depends on the accurate sequence of the functional parts of the composition, meaning that in contrary to service bundles, composite services only generate value through a valid order of their components. The authors present an abstract model as a formalization of service value networks. The model comprehends a graph-based mechanism implementation to allocate multidimensional service offers within the network, to impose penalties for non-performance and to determine prices for complex services. The mechanism and the bidding language support various types of QoS attributes and their (semantic) aggregation. It is analytically shown that this variant is incentive compatible with respect to all dimensions of the service offer (quality and price). Based on these results, the authors numerically analyze strategic behavior of participating service providers regarding possible collusion strategies.     

On the Risk of a Sovereign Debt Crisis in Italy

The intention for the Italian government to stimulate business activity via large increases in government spending is not in line with the stabilisation of the public debt ratio. Instead, if such policy were implemented, the risk of a sovereign debt crisis would be high. In this article, we analyse the capacity of the Italian economy to shoulder sovereign debt under different scenarios. We conclude that focusing on growth enhancing structural reforms, would allow for moderate increases in public expenditure.     

Consumer confusion,obfuscation and price regulation

This paper studies firms’ obfuscation choices in a duopoly setting where two firms differ in their marginal costs of production. We show that the high‐cost firm chooses maximum obfuscation while the low‐cost firm chooses minimal (maximal) obfuscation if the cost advantage is large (small). We argue that in this setting there is a new role for price regulation as it leads to more transparent pricing. Moreover, a price cap benefits social welfare as it shifts production to the more efficient low‐cost firm.     

Is it the economy,stupid? The role of social versus economic factors in people’s support for hosting the Olympic Games: evidence from 12 democratic countries

Public referenda have gained momentum as a democratic tool to legitimize public mega projects such as hosting the Olympic Games. Interest groups in favour of hosting the Olympics therefore try to influence voters through public campaigns that primarily focus on economic benefits. However, recent studies find no or hardly any economic impact of hosting the Olympics, instead providing evidence for a positive social impact. This raises the question whether citizens consider economic or social factors when deciding on hosting the Olympics. Based on representative survey data from 12 countries, our results suggest that economic factors can influence voting behaviour, although the influence of social factors is stronger.     

Energy conservation, unemployment and the direction of technical change

This paper extends the model by Smulders and de Nooij (Resour Energy Econ 25:59–79, 2003), where technical change can be biased towards labour or energy, by assuming a monopolistic union and a government which pays unemployment benefits, collects wage taxes and sells emission permits. The extended model is applied to the analysis of environmental tax reforms. A reduction in the level of energy use yields a double dividend by lowering pollution and unemployment, while temporarily inducing energy-saving technical change. It moves the economy to a new balanced growth path where unemployment is permanently lower, but long-run growth is not affected. A reduction in the growth rate of energy use induces a persistent bias in technical change towards labour and reduces long-run growth.     

Do Industries Explain Momentum?

This paper documents a strong and prevalent momentum effect in industry components of stock returns which accounts for much of the individual stock momentum anomaly. Specifically, momentum investment strategies, which buy past winning stocks and sell past losing stocks, are significantly less profitable once we control for industry momentum. By contrast, industry momentum investment strategies, which buy stocks from past winning industries and sell stocks from past losing industries, appear highly profitable, even after controlling for size, book-to-market equity, individual stock momentum, the cross-sectional dispersion in mean returns, and potential microstructure influences.     

Data Science,Predictive Analytics,and Big Data in Supply Chain Management: Current State and Future Potential

While data science, predictive analytics, and big data have been frequently used buzzwords, rigorous academic investigations into these areas are just emerging. In this forward thinking article, we discuss the results of a recent large‐scale survey on these topics among supply chain management (SCM) professionals, complemented with our experiences in developing, implementing, and administering one of the first master's degree programs in predictive analytics. As such, we effectively provide an assessment of the current state of the field via a large‐scale survey, and offer insight into its future potential via the discussion of how a research university is training next‐generation data scientists. Specifically, we report on the current use of predictive analytics in SCM and the underlying motivations, as well as perceived benefits and barriers. In addition, we highlight skills desired for successful data scientists, and provide illustrations of how predictive analytics can be implemented in the curriculum. Relying on one of the largest data sets of predictive analytics users in SCM collected to date and our experiences with one of the first master's degree programs in predictive analytics, it is our intent to provide a timely assessment of the field, illustrate its future potential, and motivate additional research and pedagogical advancements in this domain.     

Industrial structure and preferences for a common currency – the case of the EURO referendum in Sweden

Attitudes for a common currency differ from nation to nation, or from region to region. We analyse regionally differing voting results of a referendum held in Sweden in lieu of joining the European Monetary Union. We put a special focus on the role of the industrial mix – being a potential factor influencing heterogeneous transmission – and find a significant, but subordinated, impact on voting behaviour.
