Vietnam’s economy: Achievements and perspective

In last several years, Vietnams economy has reached significant achievements. Those are clearly seen by analyzing economic growth, economic structure transformation, trade and investment and Vietnams economy competitiveness. However, in the process of development, Vietnams economy is still facing many difficulties and challenges. Vietnam is accelerating speed of innovation process, is active and quicker in international economic integration in order to complete the economic – social objectives in the period of 2001–2005 with annual average economic growth rate of 7.5%.     

A Mathematical Model of Service Failure and Recovery Strategies*

Understanding the nature of service failures and their impact on customer responses and designing cost‐effective recovery strategies have been recognized as important issues by both service researchers and practitioners. We first propose a conceptual framework of service failure and recovery strategies. We then transform it into a mathematical model to assist managers in deciding on appropriate resource allocations for outcome and process recovery strategies based on customer risk profiles and the firm's cost structures. Based on this mathematical model we derive optimal recovery strategies, conduct sensitivity analyses of the optimal solutions for different model parameters, and illustrate them through numerical examples. We conclude with a discussion of managerial implications and directions for future research.     

Wavelet‐Based Testing for Serial Correlation of Unknown Form in Panel Models

Wavelet analysis is a new mathematical method developed as a unified field of science over the last decade or so. As a spatially adaptive analytic tool, wavelets are useful for capturing serial correlation where the spectrum has peaks or kinks, as can arise from persistent dependence, seasonality, and other kinds of periodicity. This paper proposes a new class of generally applicable wavelet‐based tests for serial correlation of unknown form in the estimated residuals of a panel regression model, where error components can be one‐way or two‐way, individual and time effects can be fixed or random, and regressors may contain lagged dependent variables or deterministic/stochastic trending variables. Our tests are applicable to unbalanced heterogenous panel data. They have a convenient null limit N(0,1) distribution. No formulation of an alternative model is required, and our tests are consistent against serial correlation of unknown form even in the presence of substantial inhomogeneity in serial correlation across individuals. This is in contrast to existing serial correlation tests for panel models, which ignore inhomogeneity in serial correlation across individuals by assuming a common alternative, and thus have no power against the alternatives where the average of serial correlations among individuals is close to zero. We propose and justify a data‐driven method to choose the smoothing parameter—the finest scale in wavelet spectral estimation, making the tests completely operational in practice. The data‐driven finest scale automatically converges to zero under the null hypothesis of no serial correlation and diverges to infinity as the sample size increases under the alternative, ensuring the consistency of our tests. Simulation shows that our tests perform well in small and finite samples relative to some existing tests.     

基于微观结构视角的非经常性损益噪音研究

以证监会对非经常性损益的修订为事件,选择深市2004年度披露的非经常性损益的上市公司为研究对象,采用非经常性损益的定价误差方法以及加入虚拟变量的日内收益和隔夜收益的回归分析方法,并将非经常性损益区分为非经常性收益和非经常性损失后分组进行分析,从市场微观结构角度对非经常性收益和损失的信息噪音进行研究。研究结果表明,事件日后的非经常性损失定价误差明显降低,其信息噪音降低,而非经常性收益只有最大值组的定价误差明显降低。日间收益和隔夜收益的回归结果表明,由于非经常性收益和损失造成暂时偏离价值的价格会迅速得到修正,非经常性收益和损失的信息噪音降低。证监会对非经常性损益的修订在一定程度上降低了其信息噪音,政策实施后具有一定的效果。
