Stock markets, banks, and economic growth: Empirical evidence from the MENA region

Over the last four decades, a wide theoretical debate is concerned with the fundamental relationship between financial development and economic growth. Recent studies shed some light on the simultaneous effect of banks and financial system development on growth rather than a separate impact. The empirical study is conducted using an unbalanced panel data from 11 MENA region countries. Econometric issues will be based on estimation of a dynamic panel model with GMM estimators. Thus, peculiarities of MENA region countries will be detected. The empirical results reinforce the idea of no significant relationship between banking and stock market development, and growth. The association between bank development and economic growth is even negative after controlling for stock market development. This lack of relationship must be linked to underdeveloped financial systems in the MENA region that hamper economic growth. Then, more needs to be done to reinforce the institutional environment and improve the functioning of the banking sector in the MENA region. Based on these results, other regions at the same stage of financial development such as Africa, Eastern Europe or Latin America should improve the functioning of their financial system in order to prevent their economies from the negative impact of a shaky financial market.

The Balanced Scorecard: Slogans, Seduction, and State of Play

This paper outlines claims and evidence concerning the balanced scorecard (BSC) from the research literature, integrating current thinking about its substantive content and assumptions, strategic alignment, implementation issues, judgment and decision-making, organisational performance, compensation plans, and comparisons to other performance-measurement practices. In doing so, diverse localisations of the BSC are brought into view, as well as difficulties accompanying the practice of the BSC. Future directions for practitioners and researchers are indicated.     

Africa and The Global System Disaster

Abstract: The study proposes a critical review of the national modernization project on which every African country embarked as from 1960. Beyond the number of variants of this project based on the social content of the national liberation movement and the development strategy options implemented, the author reviews what he considers to be their common denominator, applicable to the entire third world for the whole post-war (1945-90) period which he calls the Bandoung period. He describes it as a bourgeois project, although there is no real national bourgeoisie: an attempt to build “capitalism without capitalists”. He then proposes a list of its achievements, on the basis of his own criteria, that of national construction and those of the populism of some experiences. He also proposes a classification based on the supreme criterion of the logic of capitalist globalization, that of the capacity of new industries to be competitive on world markets and explains Africa's failure from this standpoint by the delay caused by colonization in solving the agricultural problem. In the light of these considerations, he reviews the nature of the challenges raised today by globalization and outlines the main features of the transformations required in the design of national and regional policies and in the organization of the world system which could sustain a new departure for Africa. Résumé: L‘étude propose une lecture critique du projet national de modernisation dans lequel l'ensemble des pays africains se sont engagés à partir de 1960. L'auteur examine, par delà la variété des variantes de ce projet tenant au contenu social du mouvement de libération national et aux options de stratégie de développement mises en oeuvre, ce qui lui apparaît constituer leur dénominateur commun, caractéristique de toute la période de l'après guerre (1945-90) pour l'ensemble du tiers monde. II qualifie cette période de Bandoung. II catalogue ce projet de bourgeois, en dépit de l'absence d'une véritable bourgeoisie nationale, et l'analyse comme une tentative de construction “d'un capitalisme sans capitaliste”. II propose ensuite un bilan de ses réalisations, sur la base de ses propres critères, celui de la construction nationale et ceux du populisme de certaines expériences. II propose également un classement fondé sur le crière suprême de la logique de la mondialisation capitaliste, celui de la capacité des industries nouvelles de faire face à la compétition sur le marché mondial et explique l’échec africain de ce point de vue par le retard que la colonisation a apportée à la révolution agricole. A à lumière de ces considérations il examine la nature des défis que la mondialisation constitute aujourd'hui et brosse les grands traits des transformations que s'imposent dans la conception des politiques nationales et régionales et dans l'organisation du système mondial, susceptibles de soutenir un nouveau départ de l'Afrique.     

Ethical perceptions of Asian managers: evidence of trends in six divergent national contexts

Global link building is having a substantial impact in every sphere of Asian managerial activity. The economic upheavals of the Asian ?nancial crisis have cast a long shadow, and ethical clarity has become a social issue. For instance, corporate performance in terms of long-term survival, growth and global competency is seen to depend to a considerable extent upon the ethical infrastructur of managers and emerging managerial culture in Asia. One ?eld in which Asian managers and their managerial practices are often considered weak is the area of ethical clarity. Corporate managerial leaders in Asia need to develop new responses to the ethical complexities arising out of the increasing global interfaces. In spite of a growing awareness of the importance of ethical centrality in an intensely competitive international business arena, very little empirical work has been conducted to strengthen the relevant management literatures. The purpose of the research reported in this paper was to examine the perceptions of ethical probity among managers in six Asian countries. The results of the study indicate interesting convergences and divergences across countries and organisational demographies. The ?ndings lead to observations of the apparent similarities of ethical conceptualisation in global, societal and often in the organisational arena while revealing noticeable divergences in the domain of individual ethical perceptions.     

A Multi-Agent Model for Overlapping Negotiations

In the last few years, research on multi-agent systems has addressed different aspects of intelligent negotiations using methods developed in different domains including game theory, decision theory, and economic models. The research proposed in Andersson and Sandholm (1999), Sandholm (1993), Sandholm and Lesser (1995) and Aknine et?al. (2004), Aknine (2002) are significant examples. However, only some of this work focuses on problems related to complex negotiations, particularly those concerning new generation applications. This new research raises fundamental difficulties we have encountered, especially in overlapping negotiations and combined negotiations. This article is interested essentially in overlapping negotiations, which include several agent roles in a same negotiation. One or more agents may play each of these roles. This work shows that the high-level negotiation models are necessary in order to control the execution of overlapping negotiation processes, since, in these negotiations we are facing both classical problems of multi-agent negotiations based on two agents’ roles and the problems concerned with the interdependence of these negotiations. Synchronization of these different processes is thus necessary because of the multiplicity of the roles. Thus, this paper presents a formalized negotiation model, which deals with this problem. It gives a theoretical analysis of the suggested model and discusses the results of the experimental evaluation. To perform this evaluation, we use the application of intelligent service agencies on the Internet.     

A proposed configurable approach for recommendation systems via data mining techniques

This study presents a configurable approach for recommendations which determines the suitable recommendation method for each field based on the characteristics of its data, the method includes determining the suitable technique for selecting a representative sample of the provided data. Then selecting the suitable feature weighting measure to provide a correct weight for each feature based on its effect on the recommendations. Finally, selecting the suitable algorithm to provide the required recommendations. The proposed configurable approach could be applied on different domains. The experiments have revealed that the approach is able to provide recommendations with only 0.89 error rate percentage.     

A machine-learning method for improving crash injury severity analysis: a case study of work zone crashes in Cairo,Egypt

Abstract

The quality of vehicular collision data is crucial for studying the relationship between injury severity and collision factors. Misclassified injury severity data in the crash dataset, however, may cause inaccurate parameter estimates and consequently lead to biased conclusions and poorly designed countermeasures. This is particularly true for imbalanced data where the number of samples in one class far outnumber the other. To improve the classification performance of the injury severity, the paper presents a robust noise filtering technique to deal with the mislabels in the imbalanced crash dataset using the advanced machine learning algorithms. We examine the state-of-the-art filtering algorithms, including Iterative Noise Filtering based on the Fusion of Classifiers (INFFC), Iterative Partitioning Filter (IPF), and Saturation Filter (SatF). In the case study of Cairo (Egypt), the empirical results show that: (1) the mislabels in crash data significantly influence the injury severity predictions, and (2) the proposed M-IPF filter outperforms its counterparts in terms of the effectiveness and efficiency in eliminating the mislabels in crash data. The test results demonstrate the efficacy of the M-IPF in handling the data noise and mitigating the impacts thereof.     

The impact of external forces on cartel network dynamics: Direct research in the diamond industry

This paper describes the impact of external environmental forces on cartel networks. Using a case research approach, this report examines two leading business networks within one industry, over time. The results suggest that (a) bargaining power of intermediaries increases with the advent of new and powerful actors, (b) process activities that cartels previously controlled are being outsourced to new actors sometimes based in developing countries, (c) other actors are acquiring resources once dominated by a cartel, (d) external forces triggered by the illegal diamond trade, such as international regulatory constraints, no longer favour cartels like De Beers, and (e) over time, these and additional environment factors are forcing actors like De Beers who perform rigid process activities to become more flexible. For example, forces are moving cartels which relied previously on hand-picked intermediaries in highly controlled networks to market their products to adopt a flexible market-focused expansion of operations in retail contexts.     

Are consumers' financial needs and values common across cultures? Evidence from six countries

Are consumers' financial needs, and financial values, the same or different across cultures? Two studies, with student (Study 1; n = 988) and non‐student (Study 2; n = 959) participants, explore the extent of equivalence, across six countries (Brazil, Russia, China, Taiwan, Tunisia and US), in financial need belief, and financial value, measurement models. The financial need beliefs, derived from self‐determination theory (SDT) principles, include financial self‐efficacy, financial autonomy, financial community trust and support; the financial values include materialism and financial altruism. Both the financial need and financial value constructs evidence configural invariance (similar factor structure), and factor invariance among student but not non‐student samples. The financial need constructs evidence full, and the financial value constructs evidence partial, metric (factor loading) invariance. Factor covariance invariance obtains for the financial need beliefs constructs but not the financial value constructs. Finally, neither financial need nor financial value constructs evidence scalar (intercept) invariance. These results provide partial support for extending SDT's hypothesis of universal human needs to the financial domain. In contrast, the financial value constructs of altruism and materialism are largely instable across cultures, suggesting that consumer views of giving, and the role of wealth in social status, differ between countries.
