Japan's concessions towards trade fairness: Mistaken western views

It is now acknowledged even by US officials that Japan's recent efforts to liberalize trade have been remarkable. Our author, who has recently published a book on “Japan's Options for the 1980s”, argues that the continuing EEC complaints about Japan's behaviour as a trading partner are unjustified: Japan is simply being made a scapegoat for the EEC's own failures.     

Are firms with state ownership greener? An institutional complexity view

This study investigates the role of state ownership in green innovation from the institutional complexity viewpoint. We posit that state ownership can be characterised by two seemingly competing logics: institutional logic, which emphasises that firms with state ownership can acquire resources to promote innovation; and efficiency logic, which states that firms with state ownership have low resource utilisation effectiveness. On the basis of the integration of both views, we suggest a U‐shaped curvilinear relationship between state ownership and green innovation. Data from Chinese listed firms from 2003 to 2015 confirm our hypothesis. Moreover, we also find two macro‐level contingencies that moderate this relationship: regional innovation readiness and industrial competition. The U‐shaped relationship between state ownership and green innovation is more pronounced when regional innovation readiness and industrial competition are higher. This study advances previous research on environmental innovation by arguing that state ownership is characterised by institutional complexity rather than being a monolithic construct.     

Differentiating Between Dimensionality and Duration in Multidimensional Measures of Poverty: Methodology with an Application to China

We develop a multidimensional poverty measure that is sensitive to the within‐individual distribution of deprivations across dimensions and time. Our measure combines features from a static multidimensional measure (Alkire and Foster, 2011a ) and a time‐dependent unidimensional measure (Foster, 2009 ). The proposed measure separately identifies—and can therefore be decomposed according to—the proportion of the poverty score attributable to: (i) the concentration of deprivations within periods; (ii) the concentration of deprivations within dimensions. In doing so it allows for a poverty ranking that is robust to assumptions about the trade‐off between the two components. Previous measures have not allowed for the features proposed here due to the inability to calculate the exact contribution of each dimension to overall poverty. We overcome this by adapting to our measure the Shapley decomposition proposed in Shorrocks ( 2013 ) (based on Shapley, 1953 ). The measure is applied to data from China, 2000‐2011.     

Evaluating Product‐Centric Continuous Improvements: Impact on Competitive Capabilities and Business Performance

Product‐centric continuous improvements (CIs) are actions via which firms modify the design of a product after the start of its production and release into the market. Product‐centric CIs are initiated to help build competitive capabilities and sustain competitive advantage throughout the product life cycle. This study complements the perspective pervasive in the extant literature that actions related to product‐centric CIs can be disruptive to firms and be associated with negative performance consequences. It investigates a topic that is relatively much less researched, namely the upside potential of product‐centric CIs. The empirical analysis is based on data collected from 144 plants in the United States representing process and discrete part manufacturing industries. Specifically, the study analyzes the impact of product‐centric CIs on competitive capabilities and business performance. The results of the empirical analysis indicate the following: First, there exist two categories of product‐centric CIs: (1) actions for quality improvement and (2) actions for cost reduction. Second, while there is a positive association between each type of CI and the intended competitive capability, there also is a trade‐off—i.e., actions for quality improvement increase quality capability but reduce cost capability, and vice versa. Third, there is a strong linkage between business performance and quality capability, but not cost capability. All in all, the study presents empirical evidence that product‐centric CIs have a significant impact on competitive capabilities related to quality and cost, and, in turn, have an impact on business performance. From the standpoint of practice, the study suggests that product‐centric CIs should be managed to develop competitive capabilities and improve business performance.     

Bus transportation crews planning by goal programming

In the present paper, an integer goal programming model formulation is presented for the bus transportation crews planning to find an optimal schedule in which each crew is assigned two days off (consecutive or non-consecutive) per week and several goals like upper and lower limits on the total number of crews having consecutive and/or non-consecutive days off on each day, lower limit on the number of crews having consecutive days off on the particular pairs of consecutive days, and minimization of the number of crews having non-consecutive days off, are taken into consideration. The model is demonstrated by a numerical example.

E-optimal minimally connected block designs under mixed effects model

Summary Considering a mixed effects model in a minimally connected block design set-up, we obtain designs which areE-optimal, uniformly in the ratio of the variance components, for inference on varietal contrasts which constitute the fixed effects in the model.
