Abstract

This study describes the structure and function of a new financial modeling technique, namely, the Artificial Neutral Network (ANN) in predicting financial markets’ behavior. With the advancement of the computer technology to date, ANN allows us to imitate human reasoning and thought processes in identifying the optimal trading strategies in the financial markets. The paper identifies the theory and steps involved in performing ANN and Generic Alogorithm in financial markets, the accuracy of the computer learning process, and the appropriate ways to use this process in developing trading strategies. It further discusses the superiority of ANN over traditional methodologies. The study concludes with the description of successful use of ANN by various financial institutions.

Abstract

Surveys African stock markets to find out if they are as efficient as developed markets, and follow the same “turn‐of‐the‐year” pattern as other markets. Compares Ghana, Zimbabwe and Nigeria, and focuses on the period between 1985 and 1995. Describes the environment of each, and computes monthly stock returns, testing them for seasonality. Finds evidence of the January effect only in Ghana, and there it is small. Notes that this may be the result of spillover from London.

Abstract

This study analyzes the effect of the North American Free Trade Agreement (NAFTA) process on two major segments of the world economy. Specifically, daily stock index returns in the North American markets and the selected Association of South East Asian Nations (ASEAN) markets during the entire agreement process are employed to analyze several NAFTA related events and their effect on respective financial markets. Using an event‐study framework, dummy variable regression analysis reveals that the significance of the events on each county appears random in nature. Joint testing of events, however, shows that except for Singapore, the overall effect of NAFTA is significant on the stock index returns of all countries.

Abstract

This study adds to the ongoing analysis of the long‐term impact of Asian financial crisis on the stock markets of eight Asian‐Pacific countries. Using current data to capture postcrisis behavior of returns, multivariate cointegration analysis reveals that a cointegrating relationship exists among the markets that transcend the financial crisis. Both vector error correction (VEC) and Granger causality tests demonstrate the profound effect of financial crisis in Korea on the returns of other countries. Granger causality tests further reveal that the events surrounding the crisis in Thailand and Indonesia largely dictate their own short‐run returns behavior since the advent of the crisis. Compared to earlier period, the post‐crisis era also experiences a closer relationship among the index returns of Hong Kong, Korea, and Singapore and a heightened degree of convergence among the returns of Asian markets.

Abstract

Traces the growth of US foreign direct investment (FDI) in India and the changing attitude of the Indian government towards it as part of its liberalization programme. Reviews previous research on the determinants of FDI and uses regression analysis on 1962‐1994 data to identify the factors affecting US FDI in India, current trends and the impact on the Indian economy. Finds that only the relatively weak exchange rate appears to be a significant factor and that US FDI has been increasing in dollar amounts and relative percentage growth, especially since the economic reforms of the 1990s. Calls for improvements in infrastructure and reductions in red tape and protectionism to encourage further growth.

Abstract

During the next decade and beyond, hospitality and leisure companies will embrace business models that focus on mass customizing travel experiences. As a result, in 2010, travel will be about engaging in powerful, seamless personal experiences that are carefully tailored to learning and catering to the tastes and demands of individual travelers. Two key forces are driving this trend on both the demand side and the supply side: globalization that allows more people to go more places, and technological advancements that will fuel economic growth and enable companies to provide experiences on demand. Most travel and leisure companies will need to make significant changes to be successful participants in this new experience marketplace. Travel companies that wish to offer differentiated experiences must do the following between now and 2010: promote customer‐experience centricity; brandish the brands: aggressively launch measures to re‐affirm the brand positioning; personalize with precision; focus on the fundamentals: guest service, revenue management, and brand building to offer a better quality product and more customized guest service with a lower cost structure; shift focus of personal: use technology for transactional tasks; refocus employees on value‐added guest services; reinvent sales and distribution using an integrated direct connect mechanism (IDCM); leverage technology advances in numerous aspects of the operations.

Abstract

Purpose

Supplier selection (SS) is one of the prime competencies in a sourcing decision. Taking into account the key role played by suppliers in facilitating the implementation of green supply chain management (GSCM), it is somewhat surprising that very little research attention has been imparted to the development of a strategic sourcing model for GSCM. This research aims to develop a strategic sourcing framework in which supplier organizations are prioritized and ranked based on their GSCM performance. Accordingly, the benchmark organization is identified and its strategy is explored for GSCM performance improvement.

Design/methodology/approach

The research develops an innovative GSCM performance evaluation framework using six parameters, namely, investment in corporate social responsibility, investment in research and development, utilization of renewable energy, total energy consumption, total carbon-di-oxide emissions and total waste generation. An integrated multicriteria decision-making (MCDM) approach is proposed in which the entropy method calculates criteria weights. The Complex Proportional Assessment (COPRAS) and the Grey relational analysis (GRA) methods are used to rank supplier organizations based on their performance scores. A real-world case of green supplier selection (GSS) is considered in which five leading India-based automobile manufacturing organizations (Supplier 1, Supplier 2, Supplier 3, Supplier 4 and Supplier 5) are selected. Surveys with industry experts at the strategic, tactical, and operational levels are carried out to collect relevant data.

Findings

The results reveal that total carbon dioxide emission is the most influential parameter, as it gains the highest weight. On the contrary, investment in research and development, and total waste generation have no significant impact on GSCM performance. Results show that Supplier 5 secures the top rank. Hence, it is the benchmark organization.

Research limitations/implications

The proposed methodology offers an easy and comprehensive approach to sourcing decisions in the field of GSCM. The entropy weight-based COPRAS and GRA methods offer an error-free channel of decision-making and can be proficiently used to outrank various industrial sectors based on their GSCM performances. This research is specific to the automobile manufacturing supply chain. Therefore, research outcomes may vary across supply chains with distinct characteristics.

Practical implications

The basic propositions of this research are based on a real-world case. Hence, the research findings are practically feasible. The less significant parameters identified in this study would enable managers to impart more attention to vulnerable areas for improvement. This research may help policymakers identify the influential parameters for effective GSCM implementation. As this research considers all aspects of sustainability, the strategies of the benchmark supplier have a direct impact on organizations' overall sustainability. The study would enable practitioners to make various strategies for GSCM performance improvement and to develop a cleaner production system.

Originality/value

The originality of this research lies in the consideration of both economic, social, environmental and operational aspects of sustainability for assessing the GSCM performance of supplier organizations. Quantitative criteria are considered so that vagueness can be removed from the decision. The use of an integrated grey-based approach for developing a strategic sourcing model is another unique feature of this study.

Abstract

The service industry is a major component of the economy. Raw material, components, assemblies, and finished products are shipped between suppliers, manufacturers, distributors, and retailers. Accordingly, timely receipt of shipped goods is crucial in maintaining the efficiency and effectiveness of such service processes. A service provider offers an incentive to the customer by specifying a competitive target time for delivery of goods. Further, if the delivery time is deviant from the target value, the provider offers to reimburse the customer for an amount that is proportional to the value of the goods and the degree of deviation from the target value. The service provider may set the price to be charged as a function of product value. This price is in addition to the operational costs of logistics that are not considered in the formulated model. For protection against deviation from target due dates, the service provider agrees to reimburse the customer. The reimbursement could be based on an asymmetric loss function influenced by the degree of deviation from the target due date as well as product value. The penalties could be different for early and late deliveries since the customer may experience different impact and consequences accordingly. The chapter develops a model to determine the amount (price) that the provider should add to the cost estimate of the delivery contract for protection against delivery deviations. Such a cost estimate will include the operational costs (fixed and variable) of the shipment, to which an amount is added to cover the expected payout to customers when the delivery time deviates from the target value. The optimal price should be such that the expected revenue will at least exceed the expected payout.
