Intra- and international commodity market integration in the Atlantic economy, 1800-1913

In this paper, the course of intra- and international market integration in the nineteenth century Atlantic economy is investigated. The most fundamental contribution of the paper is in consistently sketching the course of commodity market integration over the long run. Additionally, this study suggests that the nineteenth century has been somewhat misread in terms of the development of markets as the evidence, especially on price convergence, points to dramatic improvements in intra- and international market integration in the years prior to the mid-century. A collective task for economic historians, then, is to link these developments with the revolutionary commercial and technological developments of the post-1850 period.     

INTENSIFICATION OF RAINFED LOWLAND RICE PRODUCTION IN WEST AFRICA: PRESENT STATUS AND POTENTIAL GREEN REVOLUTION

The objective of the current paper is to explore the factors influencing the expansion and intensification of rice production in rainfed lowland sites. The village/lowland‐level data show the following: (1) the expansion of lowland rice cultivation has been driven by population pressure and accessibility to the market; and (2) the adoption of water control technologies is enhanced by the existence of immigrants and accessibility to the market. Rice cultivator data show that investment in water supply canals is influenced by land tenure security and that the canals enhance yield. This suggests that investment in water control technologies in rainfed lowland is necessary to realize a rice Green Revolution. Considering the fairly high average yield already achieved with water control technologies and the vast area of lowlands without water control technologies in rural area, there is a high potential of a rice Green Revolution in rainfed lowland in West Africa.     

The role of agricultural cooperatives in sustaining the wheat diversity and productivity: the case of southern Italy

We hypothesize that institutions such as agricultural cooperatives influence regional levels of variety diversity through input supply, processing or marketing functions. This diversity can also affect yield, a partial measure of crop productivity. We test these hypotheses with data from southern Italy, a mega-diversity spot and centre of diversity for durum wheat. Cooperatives in the southern regions of Italy process farmers’ harvests of durum wheat into bread, label it, and sell it locally. In this relatively marginalized region of the country, cooperatives enable farmers to capture more of the value of the final product and reduce marketing costs. To test the hypothesis, we apply a two-stage estimation approach with a Cobb-Douglas production function and panel data analysis. Findings suggest that the density of cooperatives in a region is associated with greater spatial diversity in wheat varieties grown, and that, over a 14-year period, this diversity positively affected crop yields.     

The role of human resource management in cross-border mergers and acquisitions

Cross-border mergers and acquisitions (M&As) have become the dominant mode of growth for firms seeking competitive advantage in an increasingly complex and global business economy. Although human resource management (HRM) can play a value-adding role in the merger process, existing research and evidence does not clearly demonstrate how it can do so. This paper addresses the neglected human side of M&As by providing a strategic fit framework to assess the link between M&A strategy and HRM strategy. Because cross-border M&As are of an order of magnitude more complex than domestic mergers, we examine contingencies in national contexts that influence outcomes in the merger process. We draw on recent empirical evidence to highlight HRM roles in terms of resources, processes and values that reflect the influence of both strategic fit and national context in the integration stage of cross-border M&A.     

Plant variety protection in developing countries. A report from the field

The establishment of intellectual property rights (IPRs) for plant varieties has caused considerable controversy, but there is relatively little empirical evidence on performance and options in developing countries. This paper summarizes the results of a recent five-country study, concentrating on the conduct of plant variety protection (PVP) regimes. It examines PVP in the context of other mechanisms that provide incentives for plant breeding. It discusses the principal options available to developing countries and examines the ability of PVP to offer protection from competing firms and from on-farm seed saving. It also looks at the administrative and management requirements of PVP regimes. Although the paper does not discuss patent protection for biotechnology it examines the IPR requirements for the introduction of transgenic varieties. Developing countries need to establish an appropriate PVP system, but PVP should be seen as part of a broader strategy for seed system development.     

PRODUCTIVITY IMPACT OF THE MODERN VARIETIES OF RICE IN INDIA

The present paper analyzed the long‐term yield growth and total factor productivity (TFP) growth by applying Tornqvist‐Theil index method for two periods, namely, 1970–85 (early Green Revolution) and 1986–2000 (late Green Revolution), for major rice‐growing states of India. The yield data shows an increasing long‐term growth trend throughout the Green Revolution period in irrigated states where modern variety (MV) adoption was nearly complete. However, yield advances started to slow down for intensive irrigated rice systems in the 1990s, whereas rainfed ecosystems have increased during the late Green Revolution period. The domestic spillovers of MV from irrigated to rainfed states is likely to be one of the contributing factors to increased TFP growth in ranifed areas after the 1980s. This implies that the MV of rice developed for irrigated ecosystems have also benefited substantially the rainfed‐dominant eastern Indian states in the long run where partial irrigation facilities such as shallow tube wells were created after the mid‐1980s.     

留样盲测方法用于原粮质量控制的研究

本文检测了稻谷、玉米和小麦留样的水分及脂肪酸值,阐明了检测期间内留样水分及脂肪酸值的变化规律,探讨了采用留样盲测方法对原粮水分和脂肪酸值检测项目进行质量控制的有效性及适用性。研究结果表明：在温度20℃～25℃、相对湿度60％-80％的保管条件下,稻谷、玉米和小麦水分项目的留样盲测数值在60天的跟踪期均较稳定,适宜用该方法进行质量监控;而对于脂肪酸值检测项目,稻谷和玉米留样再测的有效期则分别缩短至50天和35天。
