Reopening the convergence debate: A new look at cross-country growth empirics

There are two sources of inconsistency in existing cross-country empirical work on growth: correlated individual effects and endogenous explanatory variables. We estimate a variety of cross-country growth regressions using a generalized method of moments estimator that eliminates both problems. In one application, we find that per capita incomes converge to their steady-state levels at a rate of approximately 10 percent per year. This result stands in sharp contrast to the current consensus, which places the convergence rate at 2 percent. We discuss the theoretical implications of this finding. In another application, we perform a test of the Solow model. Again, contrary to prior reults, we reject both the standard and the augmented version of the model.

A Study on Strategic Value Chain and Cost Driver and PEST Analysis Method

Strategic value chain analysis method can be adopted to analyze the existing cost causality so as to confirm and optimize the value chain. Strategic cost driver analysis method that is used on the income of the owners and daily operators, production and operating activities, administration, resources, culture, etc in an enterprise can further enlarge the strategic cost scope. For analysis of the enterprise and its external environment factor, PEST analysis is represented as the extroversive analysis of cost causality. Three analytical methods of different kinds having some commonness on cost causality analysis can be combined together to form the causality analysis method, which will expand the visual angle of analysis and help to establish the integral frame of strategic cost causality analysis.     

How to improve scenario analysis as a strategic management tool?

Scenarios are claimed to support strategic decision makers. They are especially effective in dealing with uncertainties. This paper addresses some drawbacks of the conventional scenario method, which is especially directed at handling these uncertainties, and indicates possible avenues for methodological adaptations. We take the approach, which rests in the Shell tradition, as exemplary for our discussion on the mainstream scenario methodology. This approach has some limitations when it comes to dealing with simultaneous trends and countertrends, and trends or clusters of trends that are not thought of beforehand, especially the methodological requirements of causality and consistency, which might be limiting factors in this respect. This paper indicates alternative ways for scenario construction. It discusses the use of either recombinant scenarios, context scenarios, or inconsistent scenarios and/or combinations of these scenarios. These options explicitly incorporate the notion of ‘paradoxical trend’ as the codriver of future developments into the methodology.

把案例教学引入英语课堂的必要性和可行性

中国加入WTO以后，要求高等教育培养出更多的适应经济全球化需要的、能够进入国际市场进行竞争的复合型人才．这种需求对于与之不相适应的教育观念、教育结构、人才培养模式、教育内容与方法等提出了严峻的挑战。在此大背景下．对案例教学——这种培养学生实际能力的教学方法．是否可以运用到大学英语教学中来的研究就显得尤为重要。该文从案例教学的性质特征出发．阐述了运用案例教学的必要性和可行性，有助于推动英语教学方法的改革。     

DIC in variable selection

Model comparison is discussed from an information theoretic point of view. In particular the posterior predictive entropy is related to the target yielding DIC and modifications thereof. The adequacy of criteria for posterior predictive model comparison is also investigated depending on the comparison to be made. In particular variable selection as a special problem of model choice is formalized in different ways according to whether the comparison is a comparison across models or within an encompassing model and whether a joint or conditional sampling scheme is applied. DIC has been devised for comparisons across models. Its use in variable selection and that of other criteria is illustrated for a simulated data set.
