Design and development of inventory knowledge discovery system

Inventory management (IM) performance is affected by the forecasting accuracy of both demand and supply. In this paper, an inventory knowledge discovery system (IKDS) is designed and developed to forecast and acquire knowledge among variables for demand forecasting. In IKDS, the TREes PArroting Networks (TREPAN) algorithm is used to extract knowledge from trained networks in the form of decision trees which can be used to understand previously unknown relationships between the input variables so as to improve the forecasting performance for IM. The experimental results show that the forecasting accuracy using TREPAN is superior to traditional methods like moving average and autoregressive integrated moving average. In addition, the knowledge extracted from IKDS is represented in a comprehensible way and can be used to facilitate human decision-making.     

Does freezing a defined benefit pension plan affect firm risk?

This paper examines the impact of a defined benefit (DB) pension plan freeze on the sponsoring firm's risk and risk-taking activities. Using a sample of firms declaring a hard freeze on their DB plans between 2002 and 2007, we observe an increase in total risk (proxied by the standard deviation of EBITDA and asset beta), equity risk (standard deviation of returns), and credit risk following a DB-plan freeze. The increase in credit risk is reflected in a decline in credit ratings and an increase in bond yields for freezing firms. When we examine investment strategies, we observe a shift in investment from capital expenditures before the freeze to more-risky R&D projects after the freeze, and an increase in leverage. These strategies (increased focus on R&D and higher leverage) increase the operating and financial risk the firm faces. Overall, we observe an increase in risk-taking following DB plan freezes, consistent with theories that DB plans act as “inside debt” that aligns managers’ interests with bondholders’.     

Contracts for dummies? The performance of investors in contracts for difference

Investors widely use contracts for difference (CFDs) to leverage and short sell underlying financial assets. We investigate the after cost performance of investors in Australian Securities Exchange listed share CFDs, and find that market order CFD trades earn small positive returns at the daily horizon, with negative returns reported for one month to one year horizons due to financing costs. Market orders also net sell positions, which suggests that investors use CFDs for shorting opportunities. Overall, we find that liquidity demanders in CFDs obtain favourable execution, which is inconsistent with the view that CFDs are used by naive individuals.     

Working with customers: Cooperation and competition in relational marketing

The relationship and interaction between salespeople and their customers may be usefiilly examined in terms of how they believe their goals and interests are related. Twenty‐five sales persons and 40 travel agents and managers in charge of corporate travel were interviewed on specific interactions. Results support previous theorizing that productive conflict management and resulting trust and personal bonds contribute to successful marketing relationships and suggest that these dynamics occur when sales representatives and clients have developed strongly cooperative goals, but not when they have competitive or independent goals. Results were interpreted that the constructive discussion of opposing views complements cooperative goals as important contributors for developing successful relational marketing.     

Japanese management in Singapore: Convergence of human resource management practices

This paper discusses the transfer and adaptation of Japanese human resource management practices to Singapore. By comparing Japanese parent companies, their subsidiary companies in Singapore, and comparable local Singaporean companies, the modifications to the practices of the Japanese parent companies and the adoption of local practices by Japanese management are made evident. The findings seem to uphold both the convergence and the contingency theses.Dr. Chong Li Choy is a Senior Lecturer in the School of Management, National University of Singapore. Prof. Hem C.

Trading costs and price discovery

The price discovery roles of a set of related markets or securities have been investigated in many different settings where trading costs effect is often commingled with other trading arrangement factors. In Hong Kong, regular futures and mini futures contracts as well as their underlying spot asset are all traded on a same electronic trading platform. The trading arrangements thus provide us with a unique setting where we can isolate the impacts of transaction costs on price discovery. Using Hasbrouck’s (J Finance 50:1175–1199, 1995) information share approach, it is found that in Hong Kong, the regular futures contracts market plays a dominant role in price discovery while the mini futures and cash index markets play minor roles. The results in this paper provide an unequivocal support to the trading costs hypothesis.     

The Determinants and Effects of Clients Following Audit Partners Who Switch Audit Firms

Abstract

We examine the determinants of clients’ decision to follow departing partners to new audit firms and the effect of this decision on the likelihood of financial restatements. Using Taiwanese audit partner turnover data from 1984 to 2010, we find that clients are more likely to follow departing partners when the partners have more clients, longer tenure, and when both lead and concurring partners leave simultaneously. By contrast, clients are more likely to stay with their incumbent audit firms when the firms are one of the Big Four or when only the concurring partners leave. The extended partner tenure due to clients following departing partners, however, does not enhance audit quality. In fact, clients that stay at the incumbent firm experience a significant decrease in the probability of financial restatements in the first year after the audit partners leave, but clients that follow do not.     

Factors influencing strategic alliance outcomes in a manufacturing supply chain: Role of alliance motives,interdependence, asset specificity and relational capital

Integration of various theories is essential to completely understand and explain strategic alliances in a supply chain. The purpose of this paper is to develop a framework by integrating the features of transaction cost theory, resource-based theory, contingency theory, social exchange theory, and Kelley's personal relationship theory and test the framework through empirical research. The present study addresses the impact of strategic alliance motives, environment, asset specificity, perception of opportunistic behavior, interdependence between supply chain partners, and relational capital on strategic alliance outcomes. Besides, the study has also tested the role of relational capital as a central mediating construct. A sample of 2156 companies representing different industries in manufacturing in Malaysia was selected for the distribution of questionnaire. We tested the structural model using structural equation modeling (SEM). Based on the results, we conclude the following significant relationships: (1) strategic alliance motives and perception of opportunistic behavior on interdependence and relational capital, (2) interdependence on relational capital, (3) environment on strategic alliance motives, (4) relational capital on strategic alliance outcomes, and (4) the mediating role of relational capital. The current study adds significantly to the body of knowledge on strategic alliances and can help managers identify factors that influence the success of strategic alliances and provide a proper direction to develop robust and effective collaborative relationships between supply chain partners.     

Off‐Market Buybacks in Australia: Evidence of Abnormal Trading around Key Dates

Off‐market share buybacks in Australia are often structured with the buyback price comprising a large dividend component (which may carry imputation tax credits) and a small capital component. This unique structure has the consequence that institutions on low tax rates stand to benefit most from selling shares into the buyback. In this article, we explore evidence of abnormal trading activities around key dates in the conduct of off‐market buybacks and investigate the drivers of these activities. We find evidence of abnormal trading activities around the initial announcement and the final announcement dates of the buyback. The significant differences in abnormal volumes between the buybacks with and without imputation tax credits highlight the importance of tax motivations in explaining abnormal trading activities in the shares of companies conducting off‐market buybacks, and are consistent with observed buying pressure around the announcement of the buyback.
