Abstract

Purpose

The purpose of this study is to prepare new pigments derived from Red Lake C (RLC) to be applied in the inks industry and to identify their chemical nature, as well as their physical properties.

Design/methodology/approach

A number of pigments that could be applied in special printing were prepared via the reactions of RLC with appropriate Ni(II) and Zn(II) salts in aqueous and ethanolic solutions. The obtained pigments were prepared as solid compounds and characterized using different instrumental analysis such as Ultraviolet-Visible, Fourier Transform Infrared Spectroscopy, 1H NMR spectra and magnetic measurements. The physical properties of these pigments were investigated using “American Standard Testing Methods” (ASTM). After that, the pigments were applied in ink formulations to test their performance and open the way to their real applications in the printing inks industry.

Findings

The results of this work revealed that the performance of the new prepared pigments is closer to the performance of the commercial pigments which are already used in ink industry.

Research limitations/implications

Red lake C, as well as the new pigments, can be applied in other different industries such as coated papers, crayons, rubber and baking enamels.

Originality/value

The prepared pigments will be economically feasible and a good alternative to the original expensive commercial pigments which are already used in the inks industry.

Abstract

Purpose

The primary purpose of this paper is to review and critique Taleb's notion of black swan blindness for a subset of the broader field of financial economics – the search for capital adequacy rules for financial institutions who invest in residential mortgages. This search entails the analysis and prediction of extreme events in housing and mortgage markets.

Design/methodology/approach

The focus of this paper concerns efforts to assess the likelihood and consequences of extreme and consequential economic events prior to their occurrence. The goal is to assess the criticism offered by Taleb that economists overstate the understanding of extreme events. One piece of evidence consists of a case study of the literature and policies regarding capital adequacy for financial institutions who invest in residential mortgages. The other is a review of recent literature about the crisis that offers similar conclusions.

Findings

The evidence suggests that the criticism is valid. The case study reviews a number of areas in which the search for capital adequacy reflected the traits of black swan blindness as described by Taleb. The review of the recent literature about the crisis highlights a number of papers that reach similar conclusions. These include high level overviews of the literature on the crisis, e.g. Lo, a number of papers that specifically focus on housing and mortgage markets, and some very recent work about agent based modeling and complexity theory presented at the 2012 ARES meetings.

Research limitations/implications

The conclusion suggests a number of ways in which economists can combat the potential of black swan blindness is our search for extreme events. One suggestion is to combat the error of confirmation with ongoing testing. Combating overly simplistic narratives can also be addressed by listening more carefully to the criticisms by people outside the field. Pay more attention to silent evidence by having more substantial and ongoing consumer testing of new products, more work to identify best practices, and more resources to enforce lending laws. Finally, more attention needs to be focused upon assumptions in the models that are based upon limited empirical evidence and, if found later to be false, may lead to dire outcomes.

Practical implications

These include more and ongoing evaluation of stress tests. New rules to adjust capital requirements over the business cycle are consistent with the suggestions of the paper. Economists need to spend more time exploring and learning from outliers in the models.

Social implications

The recent crisis has been driven by a wide variety of factors from within many sectors and agents. The outcome has been a major problem for people in many sectors and regions of the economy. The hope is that economists can do a better job in the future to help policymakers and others be more prepared for the potential of extreme events in the hopes of avoiding them in the future or at least reducing their likelihood and damage caused by them.

Originality/value

The paper draws upon a wide variety of literature to establish its main points. Central to it is a review of an issue on which the author had substantial experience – academic and professional – and that also played a major role in the crisis – inadequate capital for an extreme downturn in house prices.

Abstract

Taints of corruption in public procurement (PP) exist in both developed and developing countries alike- though in different scales and with different characteristics and impacts. Attempts to achieve a taint-free procurement regulation have failed even in the most robust and mature jurisdictions due to an inherent complexity and difficulty given the paradigms used. PP systems today remain fragile to various shocks2 coming mainly from markets and corruption. This paper proposes a paradigm shift in the way in which a PP System (PPS) should be designed and practiced rendering it as “antifragile”3 as possible to benefit from shocks, stresses and disorder. Antifragile PPS design revolutionizes not only the regulations but also the frameworks and institutional setups and the whole practice of the public procurement profession in a manner that permits growth and evolution at times of stress or distress. This paradigm shift is based on a design of the PPS as a complex system.

Abstract

We live in the Age of Knowledge, which is impelling us towards the Age of Imagination. The technological wave rises and with it rises a wave of change that will affect both the economy and society. When these two waves will reach the coast where knowledge meets ignorance, and how to ride them, are questions that require us to imagine the future. We must, therefore, embark on the vessel of imagination, leaving behind us the baggage of what we know and understand. Imagination is not just the springboard for ideas; it also acts to connect ideas in different ways that may blossom in the garden of an entrepreneurial renaissance. Symbols, metaphors and concepts that belong to our tacit knowledge come to light in our memory. It is from here that the imagination draws its lifeblood, broadening our horizons, inducing us to interact with others who may be the bearers of other cultures. Are we ready to engage in an imaginative learning process to join business with innovation and art? Are we prepared to design a wide-open white space where the actors of entrepreneurship, innovation and art can generate a constructive tension that will sweep away what appears to be mutual antagonism or incompatibility?

Abstract

Purpose

In this study, we explored the behaviour of two Canadian multinational companies operating in the context of Arab Spring events in Egypt in 2011.

Design/methodology/approach

We conducted a fine-grained analysis of 171 documents of various secondary sources to understand the behaviour of the two firms in Egypt between 25 January 2011 and 30 June 2012.

Findings

We suggest that corporate diplomacy should be viewed as portfolios of interdependent actions rather than reactions to discrete events. We also underline the importance for organisations to have a proactive, holistic and inclusive corporate diplomacy strategy, with the objective to secure and balance both explicit political/legal licence and implicit social licence.

Research limitations/implications

We intentionally focused our empirical analysis on two Canadian firms operating in the same host country and belonging to the same industry. It would be useful to carry similar research in different organisational and institutional contexts.

Abstract

Purpose

The goal of this chapter is to discuss the foundations of ‘modern finance’, its paradigm and conceptual framework, its methods and tools, its practices and results, its governance and regulation.

Approach

The first part presents the characteristics of ‘modern finance’ and its negative effects. The second part analyses the efforts made to remedy those effects and argue about the need for a real reform.

Findings

Several aspects are pointed, for example an unreasonable ‘normality’, incentives that encourage excess, the spread of subprime crisis, etc. The contemporary finance is a ‘giant with clay feet’.

Originality/value

We need to proceed with a dual reembeddedness of finance in the economy and economy in society.

Abstract

While Big Data offer marketing managers information that is high in volume, variety, velocity, and veracity (the 4Vs), these features wouldn’t necessarily improve their decision-making. Managers would still be vulnerable to confirmation bias, control illusions, communication problems, and confidence issues (the 4Cs). The authors argue that traditional remedies for such biases don’t go far enough and propose a lean start-up approach to data-based learning in marketing management. Specifically, they focus on the marketing analytics component of Big Data and how adaptations of the lean start-up methodology can be used in some combination with such analytics to help marketing managers improve their decision-making and innovation process. Beyond the often discussed technical obstacles and operational costs associated with handling Big Data, this chapter contributes by analyzing the various learning and decision-making problems that can emerge once the 4Vs of Big Data have materialized.

Abstract

In the last decades, many of the most talented and promising young graduates in the developed economies have joined the financial industry. Simultaneously, ill-designed incentives’ schemes have favored the development of a culture in which excessive greed, free-riders’ behavior, unreasonable appetite for risk, and short-term decision making have endangered the economy and, potentially, have laid the foundations for financial, economic, social, and environmental crises.

In this chapter, we review current challenges in the financial industry from the lens of human and social capital. We examine some of the factors that allowed unethical behavior and a short-term financial focus in the financial sector, examining how compensation and an extremely competitive culture became key elements that favored greedy and manipulative behavior and ultimately generated socially harmful human and social capital in the financial sector. Finally, we discuss the emergence of a number of game-changers (namely, Brexit, FinTech, the growing relevance of ethical standards, and the increasing participation of women and millennials in the industry) that might represent potential promotors of change and help restructure and reshape the financial industry.
