The evolution of a regional container port system: the Pearl River Delta   总被引:3,自引:0,他引:3  
This study investigates the progress of container port system development in South China, focusing particularly on the interplay between Hong Kong and the other ports in the Pearl River Delta (PRD) region. After identifying the downgrading trend of Hong Kong from a transshipment hub port for Asia and for China as a whole to a regional load center and the emergence of other deep-sea direct-service ports, the paper looks into the causes of this structural change of the port system. Four major causes are identified: the cost-base competition, the impact of the unique “one-country two-systems” policy, the impact of globalization and container standardization, and the impact of multi-modal accessibility and connectivity. The paper reveals that the interplay between different governments and between the governments and port operators are the local mechanisms that together as a whole respond to the shippers’ needs and the shipping lines’ pressure. It confirms that the interdependencies and competitive relations between terminals are being played out at a regional level. While the particular situation of the PRD is unique in many regards, the features emerging there, with its dominant hub, its network of feeder ports and its emerging direct-service non-hub terminals, are being replicated elsewhere.  相似文献

A commonly held view is that the frequency and value of pre-trial settlements in civil disputes are greatly influenced by the cost allocation regime that is in place if the case goes to trial. There is a large and growing theoretical literature on this subject but almost no empirical evidence. This is due simply to the scarcity of relevant data owing to the confidentiality generally associated with such matters. However, the area is an ideal one to analyse experimentally. In this paper we consider the effect of the British and American rules for cost allocation using such an experimental methodology. We find that the two rules produce no difference in the frequency of pre-trial settlements but that the British rule produces higher settlements (pro-pursuer) if the probability of the pursuer winning is large.  相似文献

NEW YORK For Tony Hsieh, CEO at Zappos, meeting up with a customer at a bar in midtown Manhattan was perfectly natural. Most execs with 1,600 employees and doing over $1 billion in annual sales would probably pass on having drinks with an individual customer, but Hsieh is not your typical CEO. In the past week alone he had given away shoes on Twitter, sent out an open invitation to a company barbecue and solved a service problem a customer left in a blog comment. If this seems exhausting, Hsieh sees it as part of a larger strategy to build Zappos into a brand on par with Virgin.  相似文献

Fresh Juice Incorporated (FJI) is in the process of determining whether it should launch a new fruit juice, Genetically Enhanced (GE) Juice. The GE Juice meets consumers' demands for a tasty, nutritious product and it would be the first new juice product in the last fifteen years. Before FJI decides to launch GE Juice, it must analyze the uncertainty surrounding market size, market share, and price of GE Juice. Finally, if FJI decides to launch GE Juice, then they must decide if they will bottle the juice themselves or outsource this process. This case teaches students how to discuss the strategic implications of launching a new product and develop a net present value and financial feasibility simulation model given limited information.  相似文献

A fixed rate loan commitment that is binding on the lender but not on the loan applicant is equivalent to a put option. This article uses the Black-Scholes option pricing model to establish a value for fixed rate loan commitments and to derive the hedge ratio for the lending institution to hedge the interest rate risk associated with the commitments in the FHLMC forward market for mortgages. The effectiveness of the resulting hedge is tested in a simulation, where it is found that the result is a 71% reduction in the variance of the value of the lender's gain or loss associated with the commitment period.  相似文献

The debate about whether beta is dead or alive has heated up once again. We believe the empirical work supporting either side of the argument is limited because market frictions are not adequately addressed. This study clarifies the controversy about the issue by creating a new moving-average beta and analyzing two market anomalies: the turn-of-the-year and the Monday effects. What is discovered in this research is (1) that a fundamental source of the problem underlying the two types of market anomalies is the persistence of market frictions that retard the arbitrage process; (2) that beta is seriously ill if the effects of market frictions are ignored; and (3) that beta is alive and well if the effects of market frictions are accommodated. Also, we show, by using an optimal lead/lag structure, the moving-average beta provides significantly higher explanatory power for the turn-of the-year and the Monday effects than betas created from ordinary least squares regression and Scholes-Williams and Fama-French methods because the moving-average beta accommodates the effects of market frictions into the body of beta itself. This new type of beta, a moving-average beta, is demonstrated to be robust.  相似文献

AbstractThis paper outlines three ways of looking at decision processes, and relates them to problems of research management. A classification of decisions is suggested, based on three dimensions of complexity. On each dimension, innovative decisions are normally more complex than operating decisions, but since the latter are more common, there is a danger that the former will be inadequately treated, as shown in an example. These dangers may be mitigated, first, by regarding complex decision-making as an explicitly cyclical process, and, second, by recognizing the significance of reference standards. Four types of reference standard—historical, external, planning, and imaginative—are noted, and brief consideration is given to their origins and to their influence on the perception not only of problems but also of solutions. It is argued that the range and quality of the reference standards used are likely to be significant factors in the success of research management.  相似文献

Management succession and financial performance of family controlled firms   总被引:1,自引:0,他引:1  
This paper examines the immediate and long-term impacts on financial performance of 124 management successions within Canadian family controlled firms. When family successors are appointed, stock prices decline by 3.20% during the 3-day (−1 to +1) event window, whereas there is no significant decrease when either non-family insiders or outsiders are appointed. However, a cross-sectional analysis indicates that the negative stock market reaction to family successors is related to their relatively young age which may reflect a lack of management experience rather than their family connection per se. Investors are uncertain about the “management quality” of family successors who have less established reputations than more seasoned non-family insiders and outsiders. Non-family member appointments tend to follow periods of poor operating performance implying that there might be more scope for improvement when a non-family successor is appointed. Unlike the US sample in McConaughy et al. [McConaughy, D.L., Walker, M.C., Henderson, G.V., Mishra, C.S., 1998. Founding family controlled firms: efficiency and value, Review of Financial Economics 7, 1–19.], which indicates that the median percentage of votes held by controlling families is less than 15%, the Canadian sample indicates a more concentrated ownership with the median percentage of family controlled votes exceeding 51%. Of the firms in our sample, 62% use dual class capitalization to maintain control within the family.  相似文献

Commentators from diverse fields and backgrounds have argued the present innovation environment is one constituted by unprecedented levels of uncertainty. National Foresight programmes recently have emerged as a means of co-ordinating science and technology policies and responding to a condition of uncertainty and change. Perhaps the most systematic Foresight programme is that of the United Kingdom. This article discusses the response the UK Foresight programme offers to the present and future innovation environments. In doing so, it is argued we should examine how the ‘need' for the programme is constructed and how that need is defined and shaped in relation to past UK science and technology policies. It is suggested that Foresight presents an ambivalent response to many of the concerns it proposes to address.  相似文献

To value mortgage-backed securities and options on fixed-income securities, it is necessary to make assumptions regarding the term structure of interest rates. We assume that the multi-factor fixed parameter term structure model accurately represents the actual term structure of interest rates, and that the values of mortgage-backed securities and discount bond options derived from such a term structure model are correct. Differences in the prices of interest rate derivative securities based on single-factor term structure models are therefore due to pricing bias resulting from the term structure model. The price biases that result from the use of single-factor models are compared and attributed to differences in the underlying models and implications for the selection of alternative term structure models are considered.  相似文献
