Similarity of differential information with subjective prior beliefs

We present a complete, separable and metrizable topology on the product space of information and (subjective) beliefs. Such a topology formalizes similarity of differential information without the assumption of a common prior, but under the assumption that objectively impossible events are considered impossible by subjective beliefs. As an application to the theory of the consumer, we provide results on the continuity of expected utility and demand functions. We also provide continuity results for the value of information and the insurance premium as defined in the literature.     

Understanding strategic bidding in multi‐unit auctions: a case study of the Texas electricity spot market

We examine the bidding behavior of firms in the Texas electricity spot market, where bidders submit hourly supply schedules to sell power. We characterize an equilibrium model of bidding and use detailed firm‐level data on bids and marginal costs to compare actual bidding behavior to theoretical benchmarks. Firms with large stakes in the market performed close to the theoretical benchmark of static profit maximization. However, smaller firms utilized excessively steep bid schedules significantly deviating from this benchmark. Further analysis suggests that payoff scale has an important effect on firms' willingness and ability to participate in complex, strategic market environments.     

Green supply chain management – food for thought?

ABSTRACT

This paper investigates the impact of green supply chain management (GSCM) practices on the performance of UK food retail small and medium-sized enterprises (SMEs). A quantitative approach using a non-probability sampling of 84 participants was employed. Based on the literature review, five hypotheses were developed and tested using the partial least square-structural equation modeling (SEM-Smart PLS 2.03) approach. The reviewed literature revealed that key internal drivers (ID) and external pressures (EP) stimulate organizations to initiate GSCM practices in UK food retail SMEs. Though empirical findings strongly supported the statement that ID influence GSCM practices, they did not show a significant relationship between EP and GSCM practices. Literature also suggests that practicing GSCM can help improve the efficiency, brand image (BI) and profitability, and thus improve the overall firm performance which is also empirically proved. This study helps enrich existing theories on SCM and organizational performance. As to practical impact, this study should facilitate SMEs in GSCM practices and thus help green the economy. While the findings of this study have limited generalisability as the data were collected from UK SMEs only and the sample size was comparatively small, this research establishes a foundation for further study in this domain.     

Empirical Investigation of the Ability of Sensitivity of Stock Prices to Earnings News in Predicting Earnings Management and Management Forecast Errors

This paper presents an evidence that a firm’s Sensitivity of Stock Price to Earnings News (SSPEN), as measured by surplus stock demand over its supply, affects on incentives to manage earnings and, in turn, Management Forecast Errors (MFE). In particular, we find a tendency for firms rated a Sell (Buy) to engage more (less) frequently in extreme, income-decreasing Earnings Management (EM), indicating that they have relatively stronger (weaker) incentives to create accounting reserves especially in the form of earnings baths than other firms. In contrast, firms rated a Buy (Sell) are more (less) likely to engage in earnings management that leaves reported earnings equal to or slightly higher than management forecasts. The result of empirical evidence from Iranian firms in Tehran Stock Exchange (TSE) showing the existence of a meaningful relationship between SSPEN and EM. Generally, SSPEN can be used to predict EM and Forecast Errors (FEs).     

Industrial relations changes in the Maldives: critical events and actors

This paper analyses recent industrial relations (IR) and political changes in the Maldives. Critical incidents were compiled from interview and document data and analysed using a quasi‐grounded theory approach. The analysis shows that, precipitated by the political events of September 2003, profound democratic and IR changes took place, including the emergence of new IR actors and institutions. However, the outcomes of these changes proved short‐lived as old undemocratic practices were reasserted. The paper highlights the reasons why democratic and IR changes occurred as they did in the Maldives and why they reversed.     

The interplay of external punishment and internal rewards: An exploratory study of insurance fraud

Economic theories related to ethical consumer behaviour have for the most part examined the role of external incentives and deterrents, and relatively less focus has been given to the role of internal incentives. This study explores the independent and joint effects of internal rewards and external punishment mechanisms on the likelihood of consumers exhibiting unethical behaviour in insurance fraud (IF) contexts. By utilizing a data set consisting of survey data on over 43?000 consumers across 26 European countries, this study examines the interaction of internal moral values and external deterrents, affecting unethical consumer behaviour. Ordinal regression analysis and binary logistic regression were used to assess the role of internal rewards and external punishment mechanisms in the occurrence of IF. Attitudinal differences towards IF and perceptions of the probability of being caught were used to classify customers and to predict the incidence of IF. Demographic variables were also found to be correlated with IF. Perceptions of ineffectiveness of fraud investigation and detection systems by fraudulent customers significantly influences their likelihood to commit IF.     

Sustainable Product and Market Development for Subsistence Marketplaces: Creating Educational Initiatives in Radically Different Contexts*

Developing products and business processes to serve subsistence marketplaces (or the roughly 4 billion poor around the world referred to as the bottom of the pyramid) is a significant challenge for businesses. Despite the importance of subsistence marketplaces, most product development educational curricula have been focused on relatively resource‐rich and literate consumers and markets. We teach an innovative year‐long product development course which includes an international immersion experience and which covers a broad spectrum of learning from understanding poverty, to consumer behavior, to product development and engineering design specifically for subsistence consumers. This unique course represents a pioneering effort to focus attention and create knowledge about product development, marketing, management, and engineering practices for subsistence marketplaces. Our two‐semester course sequence for graduate‐level students in a variety of business and engineering disciplines and industrial design combines in‐class pedagogy with experiential learning and results in useful and marketable product concepts and prototypes. Working on projects with multinational companies or startups, students identify an opportunity of general need, conduct field market research to better understand subsistence consumer needs and contexts through an international immersion experience, develop a product concept, convert the concept to a workable prototype, and develop a manufacturing plan, marketing strategy, and overall business plan for the product. Overlaying the content found in a typical new product development lab course we develop a contextual understanding of subsistence marketplaces, setting the stage for new product development. A central aspect of the learning experience is travel to subsistence markets for actual immersion in the context and to conduct market research. Our course is at the confluence of two of the most important issues facing humanity, subsistence and sustainability. Lessons learned here can also be extended to other radically different contexts, such as future scenarios involving severe energy shortages or climate change consequences. Such educational initiatives provide challenging learning experiences in preparing students for the unique demands of the 21st century.     

Sustainable finance: A new paradigm

We argue that our current approach to shareholder wealth maximization is no longer a valid guide to creation of sustainable wealth: An emphasis on short-term results has had the unintended consequence of forcing many firms to externalize their social and environmental costs. An unwavering faith in markets' ability to efficiently uncover long-term value implications of short-term results has created many unacceptable outcomes. Given the social and environmental challenges ahead, such practices and their unacceptable outcomes cannot be sustained. Therefore, a shift in paradigm is called for. We propose a sustainable value creation framework, within which all social and environmental costs and benefits are to be explicitly accounted for.     

Does living in the vicinity of heritage tourism sites influence residents’ perceptions and attitudes?

Abstract

This study investigates whether the perceptions and attitudes of residents living within the vicinity of heritage tourism sites differ from those living further afield. It examines residents’ attitudes toward tourism development; community attachment; environment and culture attitudes; economic gain; and involvement, alongside the moderating role of distance from heritage tourism sites. In doing so, it investigates how the aforementioned factors influence residents’ perceptions of tourism development in their city. Data was collected from inhabitants of Kashan and Tabriz, two historic cities couched within Iran’s growing heritage tourism sector, and analyzed using partial least squares - structural equation modeling. The findings demonstrate significant differences between the perceptions of tourism impacts, economic gain, environmental and cultural attitudes, and involvement between residents living within the vicinity of heritage tourism sites and those living further afield. However, these findings contradicted the hypotheses; identifying higher positive perceptions, environmental and cultural attitudes, economic gain, and involvement for residents living far from heritage tourism sites. Further, the findings did not support the moderating role of distance for the effects of influencing factors on residents’ perceptions. Therefore, this study proffers significant theoretical contributions and practical implications with regards to developing sustainable tourism in Iran.     

The Effects of Securitization on Mortgage Market Yields: A Cointegration Analysis

Securitization of the residential mortgage market has completely transformed the process of financing home loans in the U.S. over the last two decades. We examine the effects of securitization on yield spreads in the primary mortgage market. Cointegration techniques are employed to test the relationship between the increasing volume of mortgage securities over time and the yield spread on mortgage loan rates. We find that a 10% increase in the level of mortgage securitization as a proportion of total mortgage originations decreases yield spreads on home loans by as much as 20 basis points. Other results indicate that, while prepayment speed has a significant effect on mortgage yield spreads, default risk does not. We conclude that securitization of the residential mortgage market plays an important role in decreasing the cost of home loans.
