Broad‐based Agricultural Development versus Food Self‐sufficiency: A General Equilibrium Analysis in India

Intersectoral linkages are analysed using a CGE model based on a SAM constructed from Indian national accounts data for 1988–89. The model includes the rural non‐farm sector, public sector production and aspects of public policy. Evidence supports the arguments of Chakravarty (1987) and Ahluwalia (1986) regarding the importance of broad‐based agricultural development as opposed to increased production in the food sector alone aimed at achieving food self‐sufficiency.     

山西票号的衰亡与金融危机的防范

山西票号衰亡的主要原因是外国直接入侵诱发金融危机和新式金融对旧式金融的浸蚀两个方面。在现阶段,外国通过直接的战争形式诱发金融危机的方式已转变为间接的经济入侵,以史为镜我国规避金融危机的方式是完善金融制度和堵塞危机产生的通道。文章研究的结果对于中国的转型经济有现实意义。     

金融集聚的区域实践、模式构建与发展对策研究

影响区域金融集聚的因素有很多,诸如政府政策、金融产业特性、资源禀赋、信息流动、金融地理运动、实体经济等。我国的区域金融中心大都处在积累建设期,区域金融集聚发展处于起步阶段。梳理我国各城市在金融集聚发展中结合自身情况走出的不同发展路径,其中存在一些不足,在反思的基础上可对我国不同区域金融集聚提出相应的发展对策和建议。     

Is it better to have loved and lost than never to have loved at all? The effect of changes in product features over time

This article examines how feature additions and removals affect consumers' preferences and the attributions they make regarding why these changes occurred. In two experiments, using a range of hypothetical and real products, we find that consumers' preferences for current product formulations are influenced by prior formulations and that changes in consumer preference are more extreme for feature removals than for feature additions. We further find that consumers attribute feature additions to causes that are more external to the firm and more stable over time than those for feature removals. Consumers' product evaluations are more negative when the cause of a feature removal is attributed more internally to the firm. However, consumers' product evaluations are not significantly affected by their attributions for feature additions. Finally, the degree to which the changing feature is linked to a brands' equity moderates these findings.     

Capital Accumulation and Convergence in a Small Open Economy

Outward‐oriented economies seem to grow faster than inward‐looking ones. Does the literature on convergence have anything to say on this? In the dynamic Heckscher–Ohlin–Samuelson model, with factor‐price equalization, there is no convergence of incomes. This is because with identical preferences and return to capital, irrespective of initial levels, the growth rates of consumption are the same. In the specific factors' model, there is factor‐price equalization in the long run, but incomes depend on endowments of non‐accumulable factors. Different specifications for the intersectorally mobile factors have different implications for development (as well as convergence).     

A neural network approach to the prediction of going concern status

The assessment of a firm's going concern status is not an easy task. To assist auditors, going concern prediction models based on statistical methods such as multiple discriminant analysis and logit/probit analysis have been explored with some success. This study attempts to look at a different and more recent approach—neural networks. In particular, a neural network model of the feedforward, backpropagation type was constructed to predict a firm's going concern status from six financial ratios, using a data set containing 165 non-going concerns and 165 matched going concerns. On an evenly distributed hold-out sample, the trained network model correctly predicted all 30 test cases. The results suggest that neural networks can be a promising avenue of research and application in the going concern area.

International Trade and Manufacturing Employment in the South: Four Country Case Studies

This paper investigates the impact of international trade on manufacturing employment in developing countries, by undertaking a comparative study of four countries—Bangladesh, Kenya, South Africa and Vietnam. It does so by employing a variety of methodological approaches: factor content; growth accounting; and econometric modelling. The main empirical finding is that international trade seems to be associated with the net creation of jobs in Bangladesh and Vietnam, with female workers being the key beneficiaries. In contrast, international trade has been associated with adverse employment outcomes in Kenya, and possibly in South Africa. This suggests that there may be crucial differences between Asia and Africa in terms of the impact of globalization on employment opportunities in manufacturing. Some alternative explanations for such differences are offered in the paper.
