Oil price forecasting under asymmetric loss

Based on the approach developed by Elliott et al. (2005), we found that the loss function of a sample of oil price forecasters is asymmetric in the forecast error. Our findings indicate that the loss oil price forecasters incurred when their forecasts exceeded the price of oil tended to be larger than the loss they incurred when their forecast fell short of the price of oil. Accounting for the asymmetry of the loss function does not necessarily make forecasts look rational.     

Managing uncertainty in on-demand air travel

Fractional management companies (FMCs) that provide on-demand air travel services experience frequent changes in aircraft availability and flight requests. We propose scheduling heuristics which are both cost-effective and persistent (i.e., close to the original schedule) to address the uncertainty. The heuristics include pro-actively enforcing idleness of aircraft in creating the original schedule, strategically repositioning aircraft to serve yet-unknown demand and dense scheduling. Computational experiments are conducted in a simulator that mimics FMCs’ daily operations. Simulation results quantify the value of each heuristic, which can be easily incorporated into existing computational methods used in FMCs for static scheduling problems.     

‘Never take pity’: an average French boxer’s ethnobiography

Based on a long-term ethnographic study of a group of French boxers, this article retraces the biography of one of its members. Éric was an average boxer who never truly mastered the art of dodging his opponents. He never left the ranks of amateur boxing either, although in fact he never truly hoped he would step into the limelight reserved for the very few champions who make it. His anonymous and relentless commitment to boxing was in fact filled with a different meaning that his ethnobiography brings to light. His commitment to boxing can be better understood in light of the trials he faced in “the poor life”, a life he described as flavorless, mired in unemployment and survival delinquency. Despite his repeated defeats in the ring, for him boxing was the only part of his identity that elevated his status and set him apart from those who only had the streets to hang out on. By revealing the meaning he gave to his pugilism, Éric’s ethnobiography offers a new perspective on the links between boxing, violence, and poverty. It also paves the way for exploring the dark side of a leisure activity and its struggles that extend far beyond the ring itself.     

The Heckscher–Ohlin model and the network structure of international trade

This paper estimates for 28 product groups a characteristic parameter that reflects the topological structure of its trading network. Using these estimates, it describes how the structure of international trade has evolved during the 1980–2000 period. Thereafter, it demonstrates the importance of networks in international trade by explicitly accounting for their scaling properties when testing the prediction of the “Heckscher–Ohlin” model that factor endowment differentials determine bilateral trade flows. The results suggest that factor endowment differentials increase bilateral trade in goods that are traded in “dispersed” networks. For goods traded in “concentrated” networks, factor endowment differentials are less important.     

Integrating art as a trans‐boundary element in a radical innovation framework

Companies have learned that radical innovations (RIs) are a prerequisite to grow organically. However, companies struggle to identify and introduce RIs, as their inherent high uncertainties and novelty challenge established organisations and management routines. To address the first challenge, companies need to take a holistic approach and design a trans‐boundary environment of creativity, trans‐disciplinary and entrepreneurial spirit. This environment attracts and retains visionary people, fosters generation of new opportunities and cultivates adaptability. By adapting evaluation metrics for RI, setting up flexible processes, and promoting trans‐disciplinary exchange, the second challenge can be addressed. Increased research has concentrated on several aspects of RI lately, but so far a combining framework is missing. Our paper bridges this gap by developing an improved theoretical framework, enhancing the existing literature and introducing art as a method to advance trans‐disciplinary interchange. In a case‐study approach, we have applied our framework to the research and development department of Vodafone Research and Development, Germany, as they integrate art methodically in their research and development process. Analysing their RI capabilities, we identify the trans‐disciplinary exchange with artists as a novel initiator and driver of RI, which has not yet been adequately considered.

Comparing Innovation Capability of Small and Medium‐Sized Enterprises: Examining the Effects of Organizational Culture and Empowerment

This study analyzes the impact of organizational culture and empowerment on innovation capability, and examines the peculiarities of these effects. The study's hypotheses are tested by applying both individual and firm‐level analyses to survey data collected from 743 employees from 93 small and medium‐sized firms located in Turkey. For medium‐sized enterprises on both the individual and firm level of analysis, results suggest that collectivism and uncertainty avoidance are positively associated with empowerment, whereas power distance is negatively related to empowerment. Assertiveness focus has no relations with empowerment and innovation capability, yet among cultural dimensions, only uncertainty avoidance is related to innovation capability. For small‐sized enterprises, findings suggest that both power distance and uncertainty avoidance are linked to both empowerment and innovation capability on the individual level, whereas two new paths between collectivism and innovation capability and between assertiveness focus and empowerment are found on the firm level. Also, empowerment is found to be positively related to innovation capability for both small and medium‐sized enterprises (SMEs) on both the individual and firm level. In terms of managerial practice, our study helps clarify the key role played by cultural dimensions in the process of shaping an empowering and innovative work environment. Findings also reveal that managers should focus on participative managerial practices (e.g., empowerment) to promote innovation capability of SMEs.
