Bank generic strategies: does Porter's theory apply in an international banking center

This study examines banks' competitive strategies and their relationship with performance in a highly internationalized banking center, Hong Kong. The factor analysis results have, by and large, provided support to Porter's three strategy typology. Nevertheless, the empirical findings from the cluster analysis and the subsequent inter-group comparison of performances have cast doubt on Porter's stuck-in-the-middle proposition by demonstrating that banks adopting a multi-strategic approach did outperform other strategically monotonous rivals. While the stuck-in-the-middle proposition is grounded in the premise of inherent inconsistencies for pursuing more than one generic strategy simultaneously, the resource-based view and the present empirical findings hint at the feasibility for well-resourced banks to combine apparently incompatible value creating activities in a synergistic way to achieve integrated flexibility and consequently, a sustainable multi-strategic position. It is suggested that this feasibility very much depends on a bank's organizing and coordinating capabilities that are developed and refined through managerial commitment, learning and experience, as well as a careful assessment of various organizational activities and its inter-relationships within the entire business system.     

A Study on Pollutant Emission Through Gas Consumption in the Hong Kong Hotel Industry

A survey of 11 hotels in Hong Kong was carried out to collect three years' energy consumption data. Regression analysis indicated that gross floor area was a major and statistically acceptable factor in explaining the gas consumption in new hotels. Based on past consumption data and some established pollutant emission factors, the amount of sulphur dioxides, nitrogen dioxides, carbon dioxides and particulate created by the Hong Kong hotel industry's gas usage during a 10-year period from 1989–1998 was estimated. The study predicts the increase in these amounts in 1999–2003 accompanying the rise in the number of hotels. The findings indicate that emissions will rise by nearly 40% in the next few years, requiring urgent discussions. The study also finds that a heat pump running on coal-fired electricity and with a coefficient of performance (COP) greater than 3 could produce lower level emissions than a gas-fired boiler. It is further suggested that an effective method to reduce the emissions is to substitute naptha with natural gas as the fuel for generating town gas and electricity. We believe the hotel industry should adopt a more proactive approach to reduce gas usage and propose the inclusion of environmental reporting in trade journals.     

Energy-saving Supporting Tourism Sustainability: A Case Study of Hotel Swimming Pool Heat Pump

Based on energy-related measurements, this article evaluates the thermal performance, energy-saving, indirect emissions and financial feasibility of using heat pumps for hotel out-door swimming pools in subtropical climates. A rooftop pool of a city-centre hotel was investigated. It was found that the average coefficient of performance (COP) was around 2.0. The measured electricity consumption was 24.6 MWh and the total heat output was 49.1 MWh for the heating season studied (mid-December to the late April). Compared with conventional electric boilers and gas-fired condensing/non-condensing boilers, the total energy savings during the heating season ranged from 26.5 to 32.5 MWh. Greenhouse and noxious emissions can also be indirectly reduced by about 12,000 kg. A discounting approach was adopted to compute the net present value of fuel costs over a lifecycle of 10 years. It was found that, over a 10-year lifecycle, the energy cost could be reduced by HK$226,400 when a heat pump with an average COP of 2.0 was used instead of a conventional electric boiler. Derived from the energy cost saving over other conventional type of water heating equipment, the simple pay-back period can be about 2 years and the lowest internal rate of return can be 39%.     

Game theoretic derivations of competitive strategies in conjoint analysis

While conjoint analysis has been applied in a wide variety of different contexts in Marketing, most applications fail to explicitly consider retaliatory reactions from competitors. In this paper, a methodological extension is developed for conjoint analysis by explicitly modeling competition in a game theoretic context. The Nash equilibrium concept is employed to model competitive reactions to produce design, and its implications for reactive product strategies are discussed. The optimal product design problem for each firm is formulated as a nonlinear integer programming problem, which is solved via a specialized branch and bound method combined with a heuristic. In order to compute a Nash equilibrium, a sequential iterative procedure is proposed. The proposed procedure is illustrated under several scenarios of competition using previously published conjoint data.This research has been supported by the Henry Rutgers Research Fellowship, Rutgers University.     

Energy Saving and Tourism Sustainability: Solar Control Window Film in Hotel Rooms

This paper investigates solar control film as an energy saver in the fast growing hotel sector in southern China. It investigates claims made for this low-cost retrofitted material in hotel rooms, calibrating reductions in solar gain in summer. It provides reliable and independent data about the performance and economic viability of solar control film in real hotel environments. The study found that, by limiting solar gain, the film helps limit tourism's impact on global warming and climate change. The paper also foreshadows new technical glazing developments.     

Spillover Effects of Internal Control Weakness Disclosures: The Role of Audit Committees and Board Connections

We find that firms are less likely to report an internal control material weakness (as mandated by the Sarbanes‐Oxley Act) in a given year if one of their audit committee members is concurrently on the board of a firm that disclosed a material weakness within the prior three years. We find a similar spillover effect for financial restatement disclosures. The spillover from material weakness disclosures is evident only if a shared director has more experience with the disclosing firm or can channel more information about the disclosed material weakness. Our findings suggest that prior director experiences outside the firm influence the work of audit committees inside the firm. One rationale is that a director's prior experience with an adverse disclosure helps diffuse important insights and serves as a catalyst for improvements in a firm's internal control and financial reporting practices. An alternative explanation, which we cannot dismiss, holds that a director's prior experience helps a firm to underreport material weaknesses and financial restatements without any attendant improvements in the underlying practices.

Influential Journals, Institutions and Researchers in Real Estate

A threshold citation approach is used to measure the research influence of academic real estate journals, institutions and individual researchers. Real Estate Economics followed by The Journal of Real Estate Finance and Economics and Journal of Real Estate Research are the most influential real estate journals. Almost 63% of heavily cited works in core real estate journals are published in real estate journals. Twenty-one percent of the heavily cited works are published in Real Estate Economics . An overwhelming 80% of the citations of the 21 most heavily cited papers in real estate come from articles published in real estate journals. Even when real estate articles are published in top-tier finance and economics journals, the majority of the citations associated with these articles come from top real estate journals. This provides strong evidence of the existence of a distinct real estate research discipline. As compared to prior studies, an expanded universe of institutions is found to influence real estate research. Research-extensive universities generating high-quality economics, statistics and finance research influence the real estate discipline. The individuals that are most influential, however, are generally those with substantial real estate discipline specific research.     

Gas storage valuation under limited market liquidity: an application in Germany

Natural gas storages may be valued by applying real options theory. However, it is crucial to take into account that most evolving gas markets, like the German spot market, lack liquidity. This implies that large-scale operation of storages reduces the achievable operating margin since storage operators will pay higher prices for injected gas and earn less on withdrawn gas. Optimal storage operation will take this into account. In this context, considering storage operators as price takers does not account for interdependencies of storage operations and market prices. This paper offers a novel approach to storage valuation taking into account the effect of management decisions on market prices. The methodology proposed within this paper determines the optimal production schedule and value by determining the stochastic differential equation describing the storage value and then applying a finite difference scheme. We find that limited liquidity lowers the storage value and reduces withdrawal and injection amounts. Further, we observe decreasing reservation prices for injection and withdrawing for growing illiquidity resulting in a left shift of injection and withdrawing threshold prices.     

Twenty-Five Years after the Fall of the Berlin Wall: An Empirical Revisit of West German Consumers' Attitudes Toward Products and Brands from Former East Germany

More than 25 years after the German reunification, data show that products/brands from the eastern regions of Germany (“Neue Länder”) still do not have significant shares in the country's western part (“Alte Länder”). To analyze potential reasons for this phenomenon, our current study replicates a previous study that investigated selected attitudes of Alte Länder consumers toward products/brands from the Neue Länder. It is shown that factors such as consumer ethnocentrism, product judgment, willingness to buy, and economic animosity continue to influence consumer behavior and as such our study offers potential explanation for the failure of Neue Länder products/brands in the western regions of Germany.
