Surges

This paper examines when and why capital sometimes surges to emerging market economies (EMEs). Using data on net capital flows for 56 EMEs over 1980−2011, we find that global factors, including US interest rates and investor risk aversion act as “gatekeepers” that determine when surges of capital to EMEs will occur. Whether a particular EME receives a surge, and the magnitude of that surge, however, depends largely on domestic factors such as its external financing need, capital account openness, and exchange rate regime. Differentiating between surges driven by exceptional behavior of asset flows (repatriation of foreign assets by domestic residents) from those driven by exceptional behavior of liability flows (nonresident investments into the country), shows the latter to be relatively more sensitive to global factors and contagion.     

Social Intermediation in Base‐of‐the‐Pyramid Markets

Our study explores the structuring decisions made by intermediaries seeking to alleviate poverty by connecting base‐of‐the‐pyramid markets with more developed markets. Using intermediation theory to ground our study, we collected qualitative data on 29 social intermediation projects located within Latin America, Africa, and Asia. Our findings suggest that ‘socializing’ intermediation theory to more accurately explain and predict structural outcomes across more diverse contexts requires three key modifications: (1) the attenuation of opportunism, which creates an internalizing social force; (2) the accommodation of non‐monetary objectives, which creates an externalizing social force; and (3) the perception of transaction capabilities as tractable, which serves as a guidepost for reconciling these two opposing social forces.     

Economic assessment of acquiring water for environmental flows in the Murray Basin*

This article is an economic analysis of reallocating River Murray Basin water from agriculture to the environment with and without the possibility of interregional water trade. Acquiring environmental flows as an equal percentage of water allocations from all irrigation regions in the Basin is estimated to reduce returns to irrigation. When the same volume of water is taken from selected low-value regions only, the net revenue reduction is less. In all scenarios considered, net revenue gains from freeing trade are estimated to outweigh the negative revenue effects of reallocating water for environmental flows. The model accounts for how stochastic weather affects market water demand, supply and requirements for environmental flows. Net irrigation revenue is estimated to be 75 million less than the baseline level for a scenario involving reallocating a constant volume of water for the environment in both wet and dry years. For a more realistic scenario involving more water for the environment in wet and less in dry years, estimated net revenue loss is reduced by 48 per cent to 39 million. Finally, the external salinity-related costs of water trading are estimated at around 1 million per annum, a quite modest amount compared to the direct irrigation benefits of trade.     

The contract,accounting and trust: A case study of an international joint venture (IJV) in the United Arab Emirates (UAE)

This paper reports on the results of a case study that examines the effect of the contract and accounting on inter-organisational trust in an international joint venture (IJV). The empirical setting of the research was an IJV relation between a United Arab Emirates (UAE) firm and its western partner. Data were gathered from multiple sources, including documents, observations, interviews and discussions with managers. The paper aims to explore the process of trust development and the role of the contract and accounting in this. We find that trust developed differently for the partners. Moreover the trust concerns of the partners were not the same. Based on this we conclude that trust was not automatically reciprocated. Instead it needs relating to other items such as the contract, accounting and also the institutional environment. The open-book accounting we observed could only be termed ‘partial’ because the western partner had access to the local partner's books but not the vice versa. But this partial open-book accounting created conflicts between the partners. We argue that developing one kind of trust through one particular medium may help one party but may damage the relationship between the partners.     

全球化与国家间的收入差距：来自81个国家面板数据的实证分析

本文运用面板数据通过基于回归的不均等分解框架，研究了全球化对国家间收入差距的影响。这一框架不但可以帮助识别决定不均等的因素，还能量化这些因素对总的不均等的贡献。实证结果表明，用贸易和外商直接投资代表的全球化带来了不均等的上升，而贸易对不均等的贡献要大于外商直接投资。另外，全球化指标的绝对和相对贡献一直在持续增加。有趣的是，当我们根据收入水平对样本进行分组研究时发现，在过去二十多年中，高收入组国家间的不均等基本保持稳定，而低收入组国家间的收入差距则扩大了。在贸易方式上的巨大差别可以解释低收入国家间的收入发散。     

An exact solution approach for vehicle routing and scheduling problems with soft time windows

A new column generation based exact optimization approach for the vehicle routing and scheduling problem with semi soft time windows (VRPSSTW) is presented. Elementary shortest path problem with resource constraints and late arrival penalties is solved as a subproblem, which rises from the Dantzig–Wolfe decomposition method. Exact solutions of VRPSSTW and hard time windows variant are compared on Solomon’s benchmark instances as well as on an instance based on Tokyo road network. It was found that the VRPSSTW solution results in fewer routes thus overall costs are reduced and late arrival penalties contribute only a small fraction to total cost.
