[Show abstract][Hide abstract] ABSTRACT: An integrated inventory system supply chain comprising of a single vendor and a single buyer is formulated to maximise the total profit of the system as whole. The optimal solution for the system, however, may not be agreeable to both parties. To ensure mutual benefit, a negotiation factor is incorporated to share profit between the players according to their contributions. The effect of permissible delay in payments is studied for sharing profit in the integrated system. The units in inventory are subject to constant deterioration. The demand is stock dependent and production rate is proportional to the demand rate. A numerical example is provided to support the development of the model. The sensitivity analysis of model parameters is carried out, it is also established that the percentage of extra total profit is higher when the players of the supply chain opt for an integrated strategy.

[Show abstract][Hide abstract] ABSTRACT: In this paper, an attempt is made to derive the retailer's inventory policy for deteriorating items under two levels of trade credit in declining market in supply chain environment. It is assumed that the retailer is a powerful decision maker. Supplier offers credit period to the retailer which in turn, partially offered to the customers by the retailer. The objective is to minimise the total cost of the retailer's inventory system with respect to the cycle time. An easy-to-use algorithm is given to decide the best policy. The numerical examples are given to illustrate the developed model and managerial issues are derived.

[Show abstract][Hide abstract] ABSTRACT: It is widely speculated that Thailand witnessed a credit crunch situation after its severe economic crisis in 1997. In this paper, we study the prevailing dispute regarding the existence (or lack of it) of credit crunch after the 1997 economic crisis. The results of the analysis using both macro- and micro-level data do not support this existence. The micro-level data include 14 industries listed under the Stock Exchange of Thailand. The results show that credit extension just changed its form from short term to long term. Both exporting and non-exporting industries had similar patterns in this regard. This paper recommends revision of leverage studies that were based on assumption of existence of credit crunch in Thailand.

[Show abstract][Hide abstract] ABSTRACT: The Summer Internship Project (SIP) is an integral part of most MBA programmes in India. Indian business schools attach a great deal of importance to such mid-course internships because they accompany a two-year cohort programme wherein the student arrives either totally without or with miniscule work experience. Indian business schools neatly sandwich the SIP between the two years. Though it is acknowledged as vital and intrinsic to inculcating managerial skills, limited attempts have been made to evaluate the effectiveness of the SIP. In this paper, we focus on: (a) the identification of the key attributes of a successful SIP, and (b) the comparative evaluation of various factors as being paramount to their learning processes from their SIP.

[Show abstract][Hide abstract] ABSTRACT: Package downsizing is a practice where the package content is reduced without changing the package or the price of the product.
In a market that is defined by ‘hyper-competition,’ package downsizing is often practiced by marketers to effect an invisible
price increase for their products. Although marketers may maintain that providing, the legally required, quantity indication
on the package is adequate for customers to make logical and informed choices, research indicates that consumers often do
not consult quantity indications on packages but use alternative methods (e.g., visual impressions of the package size, total
package price, or previous purchase experience) to judge product quantity and to calculate product value. As a subtle means,
package downsizing therefore has the potential to mislead customers in the buying process due to an unfavorable balance of
information within the dyad. This could give rise to serious moral and ethical consideration. In this paper, we examined various
issues related to package downsizing, such as why sellers resort to this type of practice, consumer vulnerability to package
downsizing, as well as the extent of protection offered to consumers by the existing laws and regulations with respect to
product packaging. Finally, we examined the ethics of package downsizing using the existing legal, moral, and professional
ethical standards as well as the principle of equivalence. Our analysis indicates that package downsizing, as it is practiced
by the marketers and sellers today, is unethical as far as the consumers are concerned.
[Show abstract][Hide abstract] ABSTRACT: This paper examines some commonly hypothesised relationships between balance sheet composition and profitability, firm size and industry in the context of the Thai manufacturing corporate sector. These relationships are examined prior to, during, and after the 1997 economic crisis. Decomposition Measures (DM) are used to represent balance sheet composition. It is found that average DM during the crisis are higher than the pre- and post-crisis for all industries, because of the deterioration of the firms' financial conditions during the period. Average DM are significantly higher for the less profitable firms in all three sub-periods, with more pronounced effect during-crisis. Larger average DM are also seen in the durable goods industries in all three subperiods because the firms in those industries had more volatility in demand. Small firms are seen to have larger average DM prior to and after the crisis. However, the effect of size is not significant during the crisis, indicating that firms of all sizes were similarly affected.

[Show abstract][Hide abstract] ABSTRACT: With an enormous amount of data stored in databases and data warehouses, it is increasingly important to develop powerful tools for analysis of such data and mining interesting knowledge from it. Data mining is a process of inferring knowledge from such huge data. The main problem related to the retrieval of information from the World Wide Web is the enormous number of unstructured documents and resources, i.e., the difficulty of locating and tracking appropriate sources. In this article, a survey of the research in the area of web mining and suggest web mining categories and techniques. Furthermore, a presentation of a web mining environment generator that allows naive users to generate a web mining environment specific to a given domain by providing a set of specifications.
[Show abstract][Hide abstract] ABSTRACT: The central sales tax (CST) in India results in a differential sales tax structure. This contributes significantly to distribution network decisions that build logistics inefficiencies in firms operating in India. In this paper, we develop a model for determining distribution centres (DCs) locations considering the impact of CST. A non-linear mixed integer-programming problem that is formulated initially is approximated to a mixed integer-programming problem. Using a numeric example, the effect of CST rates and product variety on DC locations is studied and found to be having impact. It is felt that the Indian Government proposal to switch over from the present sales tax regime to value added tax (VAT) regime would significantly contribute to reducing the logistics inefficiencies of Indian firms.

[Show abstract][Hide abstract] ABSTRACT: This research investigates the moderating impact of mogul's/entrepreneurs' persona such as innovativeness, risk-taking propensity, perseverance, and flexibility on the relationship between users' ease of use and usefulness perceptions and system usage. Perceived usefulness and ease of use are important constructs in the Technology Acceptance model (TAM), which have been generally linked to the usage of technologies-directly and indirectly. However, unique user persona, such as found among entrepreneurs, may have different implications on these relationships. This research explores such implications among the Chinese, the Indians, and the Malay entrepreneurs. Findings and implications of the research are discussed.

[Show abstract][Hide abstract] ABSTRACT: Both researchers and practitioners have recognised the salience of effective supplier selection and supplier management strategies on manufacturing flexibility. Although both agree that if the right supplier is selected and managed well, the manufacturer would be able to function more efficiently. However, there is an opposing opinion as to what supplier selection and management strategies that a manufacturer pursues and the situation that accompanies it. For example, would the manufacturer who is interested in achieving product flexibility execute similar supplier selection and management strategies compared to those seeking for launch flexibility or volume flexibility? In order to address this issue, which has remained unresolved until now and a topic of protracted debate, this study investigates the moderation effect of supplier management strategies on the relationship between supplier selection strategies and manufacturing flexibility namely, product flexibility, launch flexibility, and volume flexibility. A total of 120 manufacturers were identified from companies listed in the factory directory published by the Penang (Malaysia) Development Corporation (PDC), and a copy of the research questionnaire mailed to each of them. Out of this number, 92 usable responses were received and analysed. The results reveal that selection of supplier based on technology is important when the manufacturer is emphasising on product and launch flexibilities, but when emphasis is on volume flexibility, quality is more important. Results further show that early supplier involvement and technology roadmap are moderators of launch flexibility. In sum, the key observation from this study is that different types of manufacturing flexibility require different supplier selection and supplier management strategies. The outcome of this research adds a new insight to the current supplier selection and management-manufacturing efficiency debate, as well as provides practitioners with vital information for managing inbound activities. Details of the findings and the implications are discussed.

[Show abstract][Hide abstract] ABSTRACT: This paper discusses about the enterprise resource planning (ERP) market in India and the world. The current extension of ERP is e-CRM. The ERP market has become saturated and is on the decline; and emerging from it is the market for small and medium scale enterprises. ERP, especially in India, is being offered by small-localized players to small and medium sized firms customizing it to the needs and their pockets. Taking this cue, the big ERP players have also started offering complete solutions to the small firms. The paper illustrates this point by using the case example of Prathma, a modern blood bank in India. Prathma has been the first blood bank in India to use ERP to integrate its functions using a customized ERP. This has installed a quality check in its day-to-day operations and has significantly lowered costs. The findings of this study indicate that ERP systems promises benefit from increased efficiency to improved quality, productivity, and profitability.

[Show abstract][Hide abstract] ABSTRACT: In this paper we study how organizational learning impacts organizational behavior, and how vendor support quality enhances
product adoption and usage behavior. These constructs were verified using Application Software Packages (ASP) — a prewritten,
precoded, commercially available set of programs that eliminates the need for individuals or organizations to write their
own software programs for certain functions. The relationship between ASP usage, usage outcomes and use processes were also
investigated. Two hundred and ninety-five Chinese, Indian, and Malay entrepreneurships were studied. It was found that usage
outcome strongly determines usage, while use process has only an indirect relationship (via outcome) on usage. The impact
of organizational learning and vendor service quality on usage, usage outcome, and use process were robust. Theoretical and
practical implications of the research are discussed.

[Show abstract][Hide abstract] ABSTRACT: Theoretical exposition of the trade-environment linkage (in the form of Environment Kuznets Curve) has been extensive. While one set of studies show that with the increase in per capita income environmental degradation would decline, the other set of studies has shown that no such trend exists for developing countries. Though environmental laws are in place, firms display a very low level of compliance in developing countries. This article brings out the low level of compliance to environmental regulations in India while trying to identify the main causes.
[Show abstract][Hide abstract] ABSTRACT: Mobile phones, mobile internet access, and mobile commerce are growing much faster than their fixed counterparts. A projected number of hand-held (mobile) devices will exceed the number of stationary terminals in the world in the next few years. Nevertheless, people are unlikely to buy things using a mobile phone if there is no immediate benefit; they are likely to wait until they get to a PC, with better interface. However, successful e-commerce and solutions do not simply translate into successful mobile solutions by adding a mobile interface. Those m-commerce applications that generate significant revenue will be those specifically developed around the mobile experience; those that understand how the customer interacts with their device, the type of things the customer wants to buy, and when they want to buy them. This paper attempts to describe the fast-growing trend for tools to access the internet that will be more popular in the future than the predominant use of personal computers at the present time. A survey was conducted to understand consumer attitudes toward mobile communication and factors that would contribute to adaptation and success of this emerging technology. The outcome of this research could provide a productive strategy for managerial decision-making in this emerging wireless environment.

[Show abstract][Hide abstract] ABSTRACT: This paper provides a theoretical and empirical analysis of optimal hedging under output price uncertainty. The theoretical analysis is facilitated by exploiting the duality between production and cost while the empirical implementation uses the envelope theorem and the indirect expected utility function. Empirically estimable equations are derived by approximating the indirect expected utility function by a Taylor series approximation. The model is tested by using live cattle data as output while using prices of corn, soybeans, and the feeder cattle as inputs. The results support the theoretical predictions and the evidence shows that live cattle farmers exhibit decreasing absolute risk aversion.

[Show abstract][Hide abstract] ABSTRACT: Empirical evidence, including a recent field study in Northwest Indiana, indicates that supermarkets and other retail merchants frequently incorporate quantity surcharges in their product pricing strategy. Retailers impose surcharges by charging higher unit prices for products packaged in a larger quantity than smaller quantity of the same goods and brand. The purpose of this article is to examine the business ethics of such pricing strategy in light of empirical findings, existing government regulations, factors that motivate quantity surcharges and prevailing consumer perceptions.

[Show abstract][Hide abstract] ABSTRACT: Companies have traditionally relied on taking advantage of
price-quantity discount (PQD) on large purchases. With the adoption of
just-in-time (JIT) philosophy companies are encouraged to purchase
materials in small lots to synchronize production with deliveries. This
raised a question whether PQD is applicable in a JIT purchasing
environment. Argues that though seemingly inconsistent, JIT and PQD can
coexist. Develops an integrated JIT-PQD model to allow a buyer to decide
how much to purchase and how many shipments be placed per order.
