The Intraday Pattern of Information Asymmetry,Spread, and Depth: Evidence from the NYSE

Studies suggest that investment flows, liquidity imbalances, and institutional trading may create intraday trading patterns and opportunities for investors to time their trades to reduce transaction costs. Motivated by these studies, we divide each trading day into 13 half‐hour trading intervals and measure information asymmetry from price changes, trade sizes, and trade directions. We find that information asymmetry starts high in the morning, drops continuously until it reaches a midday low during Interval 7, rises to a midday high during Interval 10, and drops continuously after. In contrast, neither the spread nor the depth exhibit similar midday extreme values. Essentially, we identify a 90‐min window in the afternoon when net valuable information arrives to the market in high frequency while liquidity is stable, and that may be an opportunity for some investors to time their trades. In addition, we show that market makers employ dynamic strategies that change the spread, the depth, or both to manage information asymmetry. This is particularly evident during the last three trading intervals, where the significant drop in information asymmetry is countered primarily by a significant increase in the depth while the spread is almost constant.     

Managing E-Procurement Solutions Portfolio: Case Study of an Indian Steel Manufacturer

ABSTRACT

Increasingly firms are using e-solutions to fulfill their procurement needs. In the last few years, various forms of e-Procurement solutions have emerged. This case study looks into the evolution of e-Procurement solutions at an Indian steel manufacturer, Tata Iron and Steel Company (TISCO). This case study raises questions about the determinants of each solution type and its consequences. This study argues that rather than sticking to one solution, firms need to manage a portfolio of e-Procurement solutions to realize the full potential of the Internet.

Interpersonal Orientation of Spouses and Household Purchase Decisions: The Case of Restaurants

Buyer Behaviour does not occur in isolation, but within a larger social context. The family being a social unit, its members are constantly influenced by a number of external agencies, including peers, friends and relatives. This paper investigates how interpersonal orientation of spouses affects their roles, children's and others' roles in five sub-decisions of visiting a fine dining restaurant. Data were collected from young, educated couples of Singapore, who, due to their affluence and spending power are the focus of marketers in the region. Interpersonal Orientation was measured by 'Susceptibility to Interpersonal Influence', as proposed by Bearden, Netemeyer and Teel [1989]. Results showed that interpersonal orientation of spouses is an important determinant of their influence in the decision of visiting a fine dining restaurant. Also, children and 'others' were seen to play negligible roles in the service sub-decisions. Implications for restaurant marketers are discussed.     

Environmental Management Accounting: A Case Study Research on Innovative Strategy

The aim of this paper is to conduct an in-depth study on environmental management systems developed in the ceramic tiles sector. This study is conceived as an improvement on a previous survey related to an environmental diagnosis of the ceramic tiles sector where some incongruities between environmental explicit speeches and environmental actions were detected. Such incongruities revealed that firms assumed to be highly environmental committed while from facts this commitment was not so high proved. So, it was necessary to introduce case study research methodology to clarify and to understand the reasons of these inconsistencies. The main objectives of our case study research are two. The first one consists in determining the relationship between firms and environment, analysing environmental positions in companies assumed in their environmental strategy and their environmental behaviour reflected in facts, while the second one attempts to establish the role played by the accounting information system in the environmental management systems of the companies in the sector. Our case study research reveals the elaboration of a larger amount of environmental accounting information for internal use than for external one. This fact is due not only to the inexistence of regulations about environmental disclosures in Spain, at that time, but also to the importance of environmental internal accounting information for management which supports the prevalence of decision-usefulness theory in the implementation of environmental management systems.Lecturer of Management Accounting in the Department of Finance and Accounting of the University Jaume I of Castellon (Spain).

新兴证券市场开放对收益波动性的影响

证券市场开放对收益波动性的影响是衡量新兴证券市场开放风险的重要标准。亚洲金融危机后,许多学者认为新兴证券市场对外开放使得国际短期投机资本频繁流动,显著地加剧了东道国市场的波动。本文采用非对称GARCH模型,从实证角度分析1984年12月至2000年3月间14个新兴证券市场开放前后股票月收益波动性的变化。结果显示,新兴证券市场开放并不必然导致收益波动性上升,主要取决于样本国不同市场基础条件。

Brand Management as an Internationalization Strategy for SME: A Multiple Case Study

ABSTRACT

This research examines the role of branding in the Portuguese SME internationalization process and how the internationalization and brand strategies are articulated in the search for a better business performance within a competitive framework and increasing competitiveness environment. The article aims specifically at: (a) the strategy of creation and brand management; (b) the relevance given to the brand; (c) the importance of brand creation and management in the internationalization strategy. We chose a qualitative methodology, based on four cases studies. Our results suggest that branding strategies of SME cannot be compared with the strategies of multinationals. Budgetary constraints and human resources lead companies to invest in low-cost strategies. The importance of the brand lies in the distinction that allows competition with similar products within the sectors. Management of the brand does not come up as an essential strategy for the internationalization of a Portuguese SME.     

The Born-Global Phenomenon: A Comparative Case Study Research

This qualitative, case-based research investigates the most relevant traits shown by several new, export-involved born-global firms and their entrepreneurs-managers versus other more traditional and also recently-established exporting SMEs in a specific geographic region inside Spain. More concretely, we aim to shed light on the type of factors and specific conditions underlying the emergence and further expansion of born-global exporters, as compared to other counterparts, which do not share their rapid internationalising character from inception. From our cross-comparison of four firm cases investigated in this setting against a number of factors generally associated with the born-global or gradual internationalisation paths, our results indicate that both constitute two consistent and distinctive patterns of international development. Another relevant finding in this research is that born globals seem indeed to be more entrepreneurial regarding their export entry behaviour into foreign markets than gradual exporters. Relevant academic, managerial, and policy-making implications are also outlined from these results.     

The Empirical Assessment of Corporate Ethics: A Case Study

Empirical analyses of the ethics of corporations with the aim to improve the state of corporate ethics are rare. This paper develops an integrated, normative model of corporate ethics by conceptualizing the ethical quality of organizations and by relating this contextual quality to various expressions of immoral behavior. This so-called Ethics Qualities Model for organizations, which contains 21 ethical qualities, allows one to assess the ethical content of institutional groups of individuals. A proper conceptualization is highly relevant both for the empirical corroboration of business ethics theories and for managerial purposes, such as judging individual and group performance or informing external stakeholders. The empirical applicability of the model is illustrated by an explorative case study of a large, globally operating financial institution. This case-study demonstrates that the corporate ethical qualities differ with respect to their perceived optimality as well as to their estimated impact on (un)ethical conduct. The various results provide managers with many clues to understand their organization and to take effective measures to improve the ethical content of their organization.
