Using a unique market setting in Hong Kong, where (i) all firms release earnings and dividend information in the same announcement; (ii) corporate transparency is low; (iii) dividend income is non‐taxable and (iv) corporate ownership is highly concentrated, we re‐examine the corroboration effects of earnings and dividends. We use the control firm approach to avoid the return estimation bias resulting from observation clustering. We also add in variables and use econometric procedure to control for the potential impacts of earnings management, special dividends and heteroskedasticity. Our findings show that there exists a corroboration effect between the jointly announced signals. 相似文献

Tourism is a major industry in Pennsylvania, second only to agriculture. This paper examines their nexus, the rural agricultural fair. The Bloomsburg Fair provides an opportunity to explore risk management for tourism. This event, now in its 150th year, inundates a town of 12,000 with 500,000+ visitors in an 8-day period. Employing a survey of fairgoer behavior, this study explored contrasts between fairgoer and management concerns over a variety of natural and human-induced threats. It also investigated the challenges present in maintaining a quality recreational experience while simultaneously providing adequate fairgoer protection. The findings indicate that fairgoers place greater emphasis on high-probability, low-consequence events while the fair emergency management plan is largely focused on low-probability, high-consequence events such as terrorism. This disconnect suggests that a failure to understand the concerns of the fairgoer or to recognize other threats facing a destination while focusing heavily on low-probability events may create a recreation environment that is relatively less safe overall. 相似文献

This paper studies a non-preemptive two-stage flowshop scheduling problem to minimize the earliness and tardiness under the environment of a common due window. The window size and the window location are considered to be given parameters. The just-in-time problem exists naturally and has many practical applications. The problem is shown to be NP-complete in the strong sense. We develop a branch and bound algorithm and a heuristic to solve the problem. We conduct the computational experiments to test the performances of the algorithms. A strong lower bound is derived for the branch and bound algorithm that can efficiently solve 15 jobs problem for about 5 minutes. The heuristic is shown to be efficient and effective, which can solve the problem of 150 jobs for about 20 seconds and provide near-optimal solution. We justify that the heuristic is an excellent solution approach for large problem instances. We also show that four special cases are either polynomial solvable or NP-complete in the ordinary sense. 相似文献

This paper reports on a qualitative, grounded theory research project conducted in the United States, Sweden, and The United Kingdom designed to explore logistics innovation as perceived by leaders of logistics service provider firms and logistics business functions within product focused firms. Analysis of 33 depth interviews conducted within seven organizations revealed activities that reflect multiple aspects of being innovative, including: (1) setting a stage for innovation; (2) identifying clues to shifts in what customers value; (3) negotiating, clarifying, and reflecting upon insights; and (4) managing inter‐organizational learning. 相似文献

We investigate net buying pressure in the Hong Kong Hang Seng Index options market during the Asian financial crisis from July 1997 to August 1998. Our findings suggest that during this period, the dramatic changes in volatility overwhelmed the dynamics of supply and demand in the options market. The extremely high realized volatility drove market participants' expectations about future market volatility in the early months of the crisis. Findings during the late‐crisis, pre‐crisis, and post‐crisis periods are consistent with the net buying pressure hypothesis. 相似文献

Much research over the last 30 years has provided evidence that individuals display accounting fixation; that is, their cognitive process does not appropriately adapt to cross‐sectional or temporal differences in an accounting method. This paper presents the results of a quasi‐experimental test of the hypothesis that cognitive adaptation to a change in accounting method is an ordinal interactive function of three person characteristics: relevant accounting knowledge, general problem‐solving ability, and intrinsic motivation to appropriately engage in the decision task. Based on a product‐pricing decision task in which participants are provided with product costs reported by two generally employed product‐costing methods (activity‐based costing [ABC] and volume‐based costing), the results show that the majority of participants did not change their cognitive behavior when there was a change in the costing method. Further, those participants who did adapt to the change in accounting method, and thus avoided accounting fixation, did so by debiasing costs reported by volume‐based costing but not by ABC. Finally, these adapters generally exhibited high values for all three of the person characteristics compared with those who did not adapt. 相似文献

We examine the lead‐lag relation between index futures and the underlying index under three types of short‐selling restrictions on stocks in Hong Kong. Our results indicate that lifting short‐selling restrictions can enhance the informational efficiency of the stock market relative to the index futures. We also investigate the impact of two market characteristics, market conditions and the magnitude of mispricing on the lead‐lag relations under different short‐selling regimes. Our findings suggest that if we remove restrictions, the contemporaneous price relation between the futures and cash markets becomes stronger particularly in the falling market and when the cash market is relatively overpriced. 相似文献

This paper empirically assesses the suitability of the East African (EA) countries for a regional monetary union by testing for symmetry of the underlying structural shocks. The results indicate that supply and demand shocks are generally asymmetric, which does not lend strong support for forming a currency union in the EA region at the moment. However, the speed and magnitude of adjustment to shocks is similar across the countries. Therefore, further integration of the economies might lead to more favorable conditions for a monetary union. Although evidence in favor of linking an EA currency to an external anchor is weak, such support seems to favor the Euro. 相似文献

The experience of British bus deregulation has resulted in less on-the-road competition than anticipated, and a high degree of industry concentration We argue that the specific form of deregulation in Britain has created a property rights problem in the cultivation of passenger congregations at the kerb. The result has been schedule jockeying and route swamping . From a property rights perspective, the disappointing results can be seen as a commons problem. A nuanced approach to property rights at bus stops, permitting scheduled service to appropriate its investment in cultivating passenger congregations, and allowing freewheeling jitneys to compete on the route, could bring the benefits that many had expected from deregulation. 相似文献
