Measuring Production and Irrigation Efficiencies of Rice Farms: Evidence from the Punjab Province,Pakistan

We employ a non‐parametric approach, data envelopment analysis, to estimate the technical and irrigation efficiency of rice farms in the Punjab Province of Pakistan. We use a cross‐sectional dataset of 80 rice growers, including 45 tube‐well owners and 35 water buyers. Mean technical efficiency scores show that tube‐well owners and water buyers are operating at fairly high efficiency levels, indicating that access to technology is not a major constraint. However, irrigation inefficiency is pronounced, with water buyers being more inefficient than tube‐well owners. A bootstrap truncated regression is used to investigate the determinants of technical and irrigation efficiency. We suggest that groundwater management policies should be designed to address efficiency enhancing factors such as knowledge of crop water consumption requirement, better credit opportunities, outreach extension services and training programs.     

How Productive Is Workplace Health and Safety?

In this paper, we investigate the causal impact of workplace health and safety practices on firm performance, using Danish longitudinal matched employer–employee data merged with unique cross‐sectional representative firm survey data on work environment conditions. We estimate standard production functions, augmented with workplace environment indicators, addressing both time‐invariant and time‐varying potentially relevant unobservables in the production process. We find positive and large productivity effects of improved physical dimensions of the health and safety environment, specifically, “internal climate” and “monotonous repetitive work”.     

增值税转型对我国微观经济的影响

增值税的全面转型是振兴经济的一大利好消息，力度大、范围广，对企业来说，不仅能够直接减轻税收负担，改善生存环境，更能够增加流动资金，扩大企业固定资产投资需求，因而有利于促进企业的设备更新改造和高新技术企业的发展，促进利润的提升和产业升级。在这种经济背景下，文章论述了增值税转型后给企业带来的一系列影响以及应采取的相应对策。

全球价值链与国内价值链——基于投入产出表的新方法

价值链作为组织和协调经济活动的微观机制,已使经济全球化和增长模式发生了深刻的变化。本文利用来自投入产出表的新方法,测度了广东省和江苏省全球价值链和国内价值链的水平。结果表明,粤苏两省切入全球价值链的倾向高于切入国内价值链的倾向,而对其它省份关联效应较大的行业基本上是中间品行业,且具有自然资源密集的特征。全球价值链与国内价值链之间的互动关系,则关系到我国产业升级的前景和区域经济协调发展的基础。     

Causal Ambiguity in Lean Production Implementation in Malaysia

The success of the lean production system in Japan has led other companies to attempt to adopt it. Yet lean production system initiatives have seen a low success rate. This study draws on the theory of causal ambiguity and its role in the transfer of knowledge to argue that causal ambiguity can impede interfirm transfer of knowledge during lean production system implementation. The authors argue that causal ambiguity undermines motivation during lean production system implementation. Several variables are proposed as moderating the relationship. The findings of a survey are presented here.

Vertical Specialization and Trade Growth in Northeast Asia

As the global economy has become further integrated, the international production chain has become more sophisticated, with diversified stages of production located in different countries. Economic theorists have argued that the fragmentation of the global production chain is partly attributable to the high growth in international trade over the past several decades. In this study, we examine vertical specialization in China, Japan and Korea, and its contribution to these nations' trade. Using a multilevel model, it is illustrated that vertical specialization has encouraged increases in trade among all three countries. In particular, China's outcome is remarkable considering how recently it became a member of the WTO.
