The geographic and sectoral patterns of large-scale farmland investments in sub-Saharan Africa

Following the food and energy price crises of the mid 2000s, sub-Saharan Africa has become one of the largest recipients for large-scale farmland investments. While much has been written on the phenomenon, scant reliable empirical evidence is available as to the precise geographic and sectoral patterns and underlying drivers. Employing strict data quality requirements, this paper addresses these knowledge gaps by analyzing 563 farmland projects that have been established between 2005 and 2013 in sub-Saharan Africa. Findings show that the investment intensity and associated risks are not geographically uniform. Moreover, the study highlights a number of popular misconceptions regarding investor origin and their sectoral interests and motives.

产品市场竞争、流动性与公司投资

本文基于产品市场竞争的视角,探讨了公司流动性对投资的影响。使用中国A股上市公司1999~2012年的面板数据,通过联立方程组和三阶段最小二乘法进行实证检验,本文研究发现,当公司相对于行业竞争对手持有更多的流动性时,公司下一期的投资相对于行业竞争对手增加得也更多,同时相比于低掠夺风险行业,流动性对投资的正向作用在高掠夺风险行业中表现得更为明显。本文的研究表明,公司流动性具有战略价值。持有一定流动性的储备有助于公司在产品市场竞争中更好地抓住投资机会,从而获得竞争优势。     

WTO内“潜在利益”的保护:一种新的贸易干涉工具

在美国投诉欧共体"香蕉贸易体制案"中,专家组和上诉机构均支持了美国基于"潜在利益"所享有的"投诉资格"。联合国秘书长将此案作为WTO援引国家责任条款草案第42条和第48条的例证。在此背景基础上,考虑到国家基于某些WTO协议所承担的义务具有"对一切"的性质,以及WTO内既存"非违法之诉"的事实,"潜在利益"有被用作贸易干涉工具的可能性。作为贸易干涉工具的"潜在利益",既有利于促进国家更好地履行WTO义务,也可能被贸易强国用作扩张自身利益的工具。     

企业资本结构与产品市场竞争——一种新的理论视角

直到 2 0世纪 80年代 ,企业资本结构对产品市场竞争的影响才引起经济学家的广泛关注。对于这一问题的研究 ,存在着两种截然不同的理论结论 :一种观点认为企业债务水平的提高会使其在产品市场竞争中更为强硬 ,增强其竞争力 ;另一种观点则恰好相反。借鉴前人理论成果的基础上 ,尝试着提出了一种较为一般的分析框架 ,并将不同的理论成果作为这一分析框架的不同侧面。     

乡镇企业群落的市场结构、竞争与治理

乡镇企业群落在发展过程中,不同阶段均会出现一些问题,但现阶段广东乡镇企业群落中最普遍的问题就是群落内各个企业合作不足,竞争过度,即出现了局部过度竞争现象。采用梅森等人创立的SCP范式,分析企业群落内的过度竞争现象,提出群落内过度竞争问题的解决,有赖于正式治理、非正式治理及行业协会治理等模式的建立。

Brand competition in CPG industries: Sustaining large local advantages with little product differentiation

In direct competition between national brands of consumer packaged goods (CPG), one brand often has a large local share advantage over the other despite the similarity of the branded products. I present an explanation for these large and persistent advantages in the context of local competition on perceived quality or brand image. The main result of the analysis is a relation between varying degrees of product similarity and equilibrium outcomes of local share advantages. Namely, I find that asymmetric quality positioning and associated local share advantages emerge especially when competing brands are objectively similar. Conversely, local share asymmetries based on brand positioning occur less when brands are dissimilar. This paper provides two reinforcing intuitions for this result. First, if brands are objectively similar, different levels of investment in local quality perceptions co-exist in equilibrium in the same market, because this investment is often borne as fixed cost. Also, early movers will invest in high perceived quality, whereas late movers have less incentive to invest because of demand sharing and increased price competition. Second, if the local advantages are shared by competitors across markets, the persistence of these advantages is reinforced by multimarket contact. Even when local brand building is free, firms may not want to improve perceived quality in their “weak” markets if it initiates retaliation by the competition in their “strong” markets. The increase in multimarket profits from collusion is large when the products are similar, because price competition looms large.
