    Software architecture evaluation involves evaluating different architecture design alternatives against multiple quality-attributes. These attributes typically have intrinsic conflicts and must be considered simultaneously in order to reach a final design decision. AHP (Analytic Hierarchy Process), an important decision making technique, has been leveraged to resolve such conflicts. AHP can help provide an overall ranking of design alternatives. However it lacks the capability to explicitly identify the exact tradeoffs being made and the relative size of these tradeoffs. Moreover, the ranking produced can be sensitive such that the smallest change in intermediate priority weights can alter the final order of design alternatives. In this paper, we propose several in-depth analysis techniques applicable to AHP to identify critical tradeoffs and sensitive points in the decision process. We apply our method to an example of a real-world distributed architecture presented in the literature. The results are promising in that they make important decision consequences explicit in terms of key design tradeoffs and the architecture`s capability to handle future quality attribute changes. These expose critical decisions which are otherwise too subtle to be detected in standard AHP results.

    This study examines how the termination of superannuation investment mandates contributes to the departure of top fund managers in companies delegated the portfolio management role. Terminations of superannuation plan mandates increase the probability of a fund company changing the responsible fund manager. Objective-adjusted returns are also significant managerial turnover considerations. These results illustrate that significant losses of superannuation fund clients act as an external control mechanism in the investment management industry that complements internal managerial performance measures.

    This study investigates the alleged disintermediation of banks’ traditional deposit-taking in favour of investment management activities. Using data on Australian bank-affiliated funds and a nine-year record of the parent banks’ liability balances, this study finds that managed funds do not displace bank liabilities. Prudential capital adequacy requirements dissuade banks from using in-house managed investments as indirect conduits for raising funds in the same manner as deposit-taking.

    We examine the impact of several factors on the selection of portfolio managers for Australian pension plan mandates. Performance measures do not affect the probability of a mandate allocation. Pension sponsors tend to choose managers with top-quartile five-year performance who have recently beaten a market benchmark. Management expenses have a negative impact on a manager’s chances. A surprising result is sponsors’ tolerance for high portfolio trading costs. Mandates are spread across manager investment styles. The style and institutional attributes of preferred managers suggest trustees’ reputation and prudential concerns matter, particularly for the aggregate annual mandate allocations.

    Journal Article
    Purpose – To provide a social-theoretic framework which explains how e-commerce affects social conditions, such as availability of information and equality of access to information, influences actors’ behavior, shapes e-commerce business models, and in turn impacts industry structure. Design/methodology/approach – Empirical investigation based on one-hour interviews with owners/managers of nine vehicle dealerships and six vehicle buyers in a large US metropolitan region. The hermeneutic method of understanding was used, involving a circular process from research design and attentiveness to data, to data collection and interpretation. This circular process exemplified the dialectic relationship between the theoretical framework (derived from Habermas’s Theory of Communicative Action) and empirical data, through which interpretation and theoretical explanations grounded in the data emerged. Findings – Demonstrates that e-commerce gives rise to increasing competition among the dealers, decreasing prices and migration of competition to price, decreasing profitability of the average dealer, and erosion of traditional sources of competitive advantage. Moreover, e-commerce emancipates and empowers vehicle purchasers while reducing the power of automobile dealers. Research limitations/implications – The research findings focus on the effects of e-commerce on the automobile distribution industry. However, one could argue that a number of the findings extend to other retailing-based industries. Practical implications – The paper illustrates a research methodology that may be useful to study other e-commerce applications. Originality/value – This paper illustrates the application of Habermas’s Theory of Communicative Action to studying the effect of e-commerce.

    This paper investigates the nature of the stock market linkages in the advanced Asia-Pacific stock markets of Australia, Hong Kong, Japan and Singapore with the US and the information leadership of the US and Japan in the region since the early 1990s. It has been found that both the contemporaneous return and volatility linkages were significant and tended to be more intense after the 1997 Asian crisis period. However, the investigation of the dynamic information spillover effects in terms of returns, volatility and trading volume from the US and Japan did not produce such time-varying influence. In general, significant dynamic information spillover effects from the US were found in all the Asia-Pacific markets, but the Japanese information flows were relatively weak and the effects were country specific.

    Journal Article
    We examine the influence of the European Monetary Union (EMU) on the dynamic process of stock market integration over the period 2 January 1989-29 May 2003 using a bivariate EGARCH framework with time-varying conditional correlations. We find that there has been a clear regime shift in European stock market integration with the introduction of the EMU. The EMU has been necessary for stock market integration as unidirectional causality was found. Linear systems regression analysis shows that the increase in both regional and global stock market integration over this period was significantly driven in part, by macroeconomic convergence associated with the introduction of the EMU and financial development levels.

    We investigate the impact of scheduled government announcements relating to six different macroeconomic variables on the risk and return of three major US financial markets. Our results suggest that these markets do not respond in any meaningful way, to the act of releasing information by the government. Rather, it is the `news` content of these announcements which cause the market to react. For the three markets tested, unexpected balance of trade news was found to have the greatest impact on the mean return in the foreign exchange market. In the bond market, news related to the internal economy was found to be important. For the US stock market, consumer and producer price information was found to be important. Finally, financial market volatility was found to have increased in response to some classes of announcement and fallen for others. In part, this result can be explained by differential `policy feedback` effects.

    This paper provides empirical evidence on the linkage between foreign exchange market volatility and daily 90-day covered interest rate parity (CIP) conditions of the three major exchange rates against the US dollar (US$). Markov regime shifting models were utilized to generate time series of volatility regime probabilities and these were used to explain the first and second moments of the daily deviations from and the transaction cost bands around the covered parity conditions. We find a significant positive relationship between the deviations and the regime probabilities, indicating an increasing probability of higher volatility state being associated with rising deviations (both first and second moments) from the parity condition. Similar positive relationship is found for the transaction bands. Rising (falling) probabilities of high (low) volatility regimes increased the first and second moments of the bands. Furthermore, we find a higher volatility state combined with a US$ depreciation is associated with significantly higher volatility in the daily deviations than an appreciation. Also, US$ depreciation is associated with widening transaction bands. This suggests that the level of market uncertainty was higher when the US$ was depreciating.

    This paper investigates the nature of information leadership of the US and Japan in the advanced Asia-Pacific stock markets. Instead of just relying on return and return volatility spillovers from major markets, specific and disaggregated news events are also utilized. In particular, the aim is to examine the nature of spillover effects of scheduled announcements of the US and Japanese macroeconomic variables in the advanced Asia-Pacific stock markets of Australia, Hong Kong and Singapore for the period 2 January 1991 to 31 May 1999. The investigation reveals that both US and Japanese announcement news elicit significant first and second moment influences on the returns of the other markets, in general, and that there is a complex array of significant market responses to various news announcements. There is also strong evidence of markets responding differently to bad news announcements compared to overall news (including both good and bad news) announcements which indicate that the information content of each economic announcement is a source of tradable information rather than the act of releasing economic figures. Thus, this paper contributes to the literature by shedding light on the important drivers of the documented information leadership of the US and Japanese stock markets.
