Contagion Risk

PurposeThis paper offers an alternative approach to assessing contagions in price and load in the Australian interconnected power markets. This approach enabled us to identify a high-risk region and assess the direction of contagions from both buyers' and sellers' perspectives.Design/methodology/approachThe author used a multinomial logit method to measure contagions. Having identified the exceedance and coexceedances, the author estimated the multinomial logit coefficients of the covariates explaining the probability of a certain number of coexceedances.FindingsMarket participants should recognize the presence of contagion risk and scrutinize price and load dynamics in the NSW and VIC regions to anticipate any simultaneous extreme changes. Regulators need to stabilize the demand and supply sides in those regions to minimize any possible contagions.Originality/valueThis paper presents a pioneering study investigating contagion in the Australian interconnected power markets.

Purpose Benzene contamination has been reported in some food groups. This study aims to identify high-risk foods groups to assess exposure to benzene. Design/methodology/approach Benzene is a hazardous volatile organic compound commonly used in the production of chemicals, detergents, paints and plastics. In addition, benzene is present in food and beverages. Findings Citrus juice-based beverages are usually more contaminated with benzene than other beverages. Benzene was also detected in carbonated beverages, fruit juices, pickles, lime juices, mayonnaise and salad dressing. Smoked and canned products have higher content of benzene. Aromas that are used in food contained benzene. Food packaging is one of the sources of benzene contamination of food. One of the reasons for its formation in food staff is due to the reaction of vitamin C (or similar acid) with benzoate, which is mainly used as a preservative in various foods. Practical implications Foods contaminated with benzene were determined. Moreover, mechanisms of its formation and some preventive measures were discussed. Originality/value This review determined the amount of benzene in foods, mechanism of formation and suggestion for prevention of benzene contamination in food.

PurposeThe study aims to explore the possibility of redefining success in tourism and measuring such a phenomenon by considering alternatives to economic factors, and to identify the ways such measurement could be implemented.Design/methodology/approachThe study reviews and explains current approaches to defining and measuring success in tourism in the literature, followed by identification of alternative factors which could be measured and the implications of such a change in approach.FindingsThere has been a long-standing emphasis and priority placed on measuring tourism at the national level with a focus on economic criteria, and this has been followed at regional and local levels. The result has been that success has become equated with volume, supporting the aim of continued growth in tourism. Such an approach and attitude mitigate against achieving or moving towards sustainability, and other measures are needed to avoid problems such as overtourism.Originality/valueThere has been little discussion of moving to a wider range of indicators of success in tourism, and the previous focus has been on economic criteria and competitiveness as shown by tourist numbers. This paper presents a discussion of an alternative approach, showing that tourism stakeholders from national to local levels need to redefine success as including factors such as community and environmental well-being and focus on a wider concept of success. Using existing data and organisations would enable measuring such concepts to be done without major change or greatly increased costs to agencies.

Purpose – The purpose of the paper is to summarize the Commodity Futures Trading Commission's (CFTC) recent overhaul of its customer protection rules, which regulate how futures commission merchants (FCMs) and derivatives clearing organizations (DCOs) handle customer funds. Design/methodology/approach – The paper summarizes the most significant aspects of the CFTC's October 30, 2013 customer protection rulemaking, explains FCM and DCO obligations under the new regulatory regime, and sets forth a compliance timeline. Findings – The CFTC's recent overhaul of its customer protection rules impose significant new requirements on FCMs and DCOs in their handling of customer funds. Practical implications – All FCMs and DCOs that handle customer funds should review these new rules and begin putting into place policies and procedures to ensure their compliance as each new requirement comes into effect. Originality/value – The CFTC's overhaul of its customer protection regime is new and significant. FCMs and DCOs need to understand their new obligations under the rules. As these new rules are the CFTC's regulatory response to the events that led to the insolvencies of MF Global and Peregrine Financial Group, these developments also should be of interest to futures and swaps market participants generally.

Purpose The purpose of this paper is twofold: first, to investigate the motives of urban consumers when purchasing local food products using means-end chain (MEC) analysis and second, to introduce an alternative approach to segment the market based on consumers’ motivation using decision segmentation analysis (DSA). Design/methodology/approach DSA was used as advanced segmentation procedure of hierarchy value maps (HVMs) produced by MEC analysis. Findings The findings suggest that there are two main segments of local food consumers in urban Indonesia: value-for-money and health benefits. The value-for-money segment is dominant when making local food purchasing. Research limitations/implications This study sample is not representative of local food consumers in urban Indonesia as only three urban cities were interviewed. Practical implications An understanding of the motivation-based segmentation of local food in urban cities is a useful tool in order to reinforce and attract local food consumers to consume more locally grown food. Originality/value This study reveals the motivation-based segmentation of local food in urban cities in Indonesia.

Purpose The purpose of this paper is to discuss how a seller can use interactions to respond to public procurement needs for innovation when the buying side is restricted by public procurement regulations. Design/methodology/approach The authors collected data using qualitative semi-structured interviews of different empirical examples, in which private–public interactions of four different high-technological products are studied. Two products belong to the defence industry and two to the civil industry. Findings The findings point to three types of innovations in public procurement: product, service and business model. The empirical examples further indicate, as suggested in previous studies, that innovation is hindered by regulations that limit interaction between suppliers and the public. In addition, the empirical examples indicate that firms mobilize actors in their network when the buyer is restricted in regard to interaction. The findings also add to the IMP literature by comparing interactions in the three types of innovations in the public procurement context. Originality/value Public procurement is an area where innovations are lagging behind, compared with private procurement. Research points to limited interaction between actors as an obstacle to innovation in public sector collaborations. This paper extends the literature on how organizations interact in the setting of public procurement. The authors identify demand and supply triggers for three types of innovations: product, service and business model innovation.

PurposeThe authors investigate whether matchings in equity crowdfunding are more likely to happen if homophily exists between investors and investees. They focus on gender, age and geographical proximity as crucial dimensions of similarity among individuals and thus of homophily. Furthermore, they investigate whether the effect of homophily depends on the risk of opportunism, which investors allegedly attribute to proponents basing on their area of residence.Design/methodology/approachThe authors analyze a hand-collected database of 13 equity crowdfunding campaigns launched by Italian innovative start-ups from January 2013 to June 2016, which includes information about 384 equity crowdfunding investments carried out by 361 different investors.FindingsThe authors find a significant effect of geographical proximity and age similarity in explaining the probability that an investor finances a campaign. Moreover, these effects are particularly relevant if the proponent is located in areas characterized by a high risk of opportunistic behavior. Interestingly enough, they do not detect any significant effect related to gender.Originality/valueIn this paper, the authors have the unique opportunity to analyze a whole market (the Italian market) during three years, from inception (2013–2016), and to collect the identities of the investors in all successful campaigns.

Purpose – Intra and inter-organisational learning holds important consequences for official agencies’ capabilities to reduce harm, particularly in the field of safeguarding children. A range of formal learning mechanisms exist but as these can be limited there is a case for expanding the learning opportunities relied upon. The concepts of “red teaming” and “alternative analysis” though relatively well established in other sectors are under-developed, under-used and under-promoted within policing. They offer flexible conceptual and practical resources that aim to challenge established models, thinking and practices. Policing organisations would benefit from institutionalising alternative forms of analysis though this would involve an attitudinal commitment and shift. This paper aims to discuss these issues. Design/methodology/approach – Documentary analysis and reflection. Findings – Consideration of the red team approach by police and partners offers an alternative approach to effective organisational learning to prevent repeating similar mistakes uncovered by Serious Case Reviews. Originality/value – This paper will allow practitioners to reflect upon current serious reviews of cases and offers an alternative and effective way of improving partner agencies capabilities to reduce harm.

Purpose The article offers an innovative process for collaborating with people you don’t agree with or like or trust . Design/methodology/approach Based on his experience as a collaboration facilitator in national and regional conflicts and stalemates, the author explains how to achieve success through what he terms “stretch collaboration.” Findings Stretch collaborations requires participants to take three unconventional approaches. Practical implications Unconventional “stretch collaboration” abandons the assumption of control. It gives up unrealistic fantasies of harmony, certainty, and compliance, and instead embraces messy realities of discord, trial and error and co-creation.” Originality/value Managers and leaders increasing must collaborate with stakeholders who have opposing interests. This stretch collaboration process offers a way to make progress even in volatile, hostile, high-risk situations.

Productive Activities

Purpose – Since Baumol (1990), the economic literature has distinguished between two broad categories of entrepreneurship: productive and unproductive. The purpose of this paper is to introduce another subcategory: indirectly productive entrepreneurship. Sometimes, profit-seeking entrepreneurs allocate their talents to indirectly productive activities to mitigate the new costs market participants endure as a result of a government regulation. The resources used to mitigate these costs must be diverted from other uses. Design/methodology/approach – This paper uses the example of cell phone storage outside New York City’s high schools to illustrate an indirectly productive entrepreneurial activity that mitigates the inefficiencies or costs created by a regulation. These costs and the resulting entrepreneurship would not have arisen absent the regulation. Findings – These profit opportunities do not result from market entrepreneurial errors or successes but emerge from inefficiencies or unintended consequences produced by government regulations. When evaluating such entrepreneurship, the question is whether such regulation is desirable from an efficiency viewpoint because such entrepreneurship, while making such regulation less inefficient or less costly, diverts resources from other lines of production. Originality/value – This paper identifies a new category of entrepreneurship: indirectly productive entrepreneurship. This paper also shows that government regulation often deters productive entrepreneurship. However, under some circumstances, regulation can indirectly encourage productive entrepreneurship by creating artificial profit opportunities that would not have existed otherwise.

Insight Into

Purpose The purpose of this paper is to gain insight into enterprise resource planning (ERP) research by framing ERP intellectual contributions using a knowledge-centric taxonomy that was originally proposed as an organizing framework for classifying conceptual contributions in marketing. Thus the paper provides a better understanding of existing gaps and future opportunities in ERP research. Design/methodology/approach Using MacInnis framework, the authors classified a sample of 300 ERP articles published during the period 2000-2014 into a topology of four generic contributions types and eight sub-types. Findings The findings indicate that whereas the explicating type received the most attention by researches, the debating type received the least. It also seems that there is a temporal dimension to the different types of conceptual contributions. Identification of usefulness of the ERP systems to business was not addressed as would have been predicted by the build-evaluate lens of March and Smith framework. Research limitations/implications The main limitation of this research is that only used articles from scholarly journals, and did not include conference proceedings, books, and other outlets. Another limitation is that the search criteria was title-based, which may have missed some relevant papers. Research implications include highlighting the importance of a knowledge-centric view of ERP research, and practical implications include the call for robust measurement criteria for ERP benefits and rigorous ERP comparison schemes. Originality/value The main contribution is providing an alternative approach to framing the ERP intellectual contributions. The proposed taxonomy revealed major areas of focus and opportunities for future ERP research emphasis. To the best of the authors’ knowledge, this is the first instantiation of MacInnis framework into ERP research.
