The impact of agricultural policy distortions on the productivity gap: Evidence from rice production

This article explores how production and trade policy distortions affected rice productivity in 33 rice-producing countries. A rice-productivity index is constructed, and a model linking the productivity gap with policy distortions is presented. After controlling for the differences in infrastructure, access to inputs and equipment, openness, and human capital, this article shows that high levels of rice subsidies and protection in rich countries combined with taxation of rice farming in poor countries widened the gap in rice productivity between rich and poor rice countries.     

Biofuels and the poor: Global impact pathways of biofuels on agricultural markets

This study seeks to assess the future impacts of biofuel production on regional agricultural and related sectors over the next decade with a specific focus on the vulnerable regions of developing nations. Using a modification of the GTAP modeling platform to account for the global interactions of regional biofuel and food markets, the analysis shows that biofuel production levels depend on the assumption about the future price of energy and the nature of the substitutability between biofuels and petroleum-based transport fuels. Low energy prices reduce the demand for biofuels and thus require greater government support to meet the desired production targets. At the other extreme, when prices are high and there is scope for substituting biofuels for petroleum-based fuels, the volume of biofuels produced will exceed the mandates. Even when biofuels are being mainly produced in developed countries, our results indicate that there are impact pathways that extend far beyond the borders of the US, Brazil and the EU. Prices of feedstock and non-feedstock commodities rise in developing countries. There is also a rise in value added from the agricultural sector—a gain that is enjoyed by the owners of land and labor, including unskilled. Hence, to the extent that agriculture is a key sector in getting growth started and addressing poverty needs, the emergence of biofuels can (in this way at least) be a positive force.     

Land inequality,government ideology and agricultural protection

This paper presents an empirical investigation of how agricultural land ownership inequality and government ideology (right-wing vs. left-wing) affect agricultural protection. Theoretically, the links are quite ambiguous, switching from positive to negative depending on the structure of the underlying political economic model – i.e. pressure groups vs. median voter approach. The data show, overall, that protection is decreasing in land inequality and with left-wing government orientation, but not in a linear fashion: left-wing governments tend to support agriculture in more unequal societies. There is some evidence that the relationship holds better in democracies than in dictatorships.     

Wheat markets,food aid and food security in Afghanistan

In Afghanistan, after two decades of civil strife and successive droughts from 1998 to 2002, large inflows of food aid, distributed mainly to returning refugees and through food for work programs, have helped offset production shortfalls of wheat, the country’s major staple. At the same time, private international trade from neighboring countries, especially Pakistan, has also played a major role in augmenting wheat supply and stabilizing prices.     

The effects of manufacturer's organizational learning on distributor satisfaction and loyalty in industrial markets

The main objective of this study is to examine the effects of organizational learning (OL) on satisfaction and loyalty in industrial markets. A conceptual model, in which the unit for analysis is the dyadic relationship between manufacturers and their main distributor, is proposed and tested. The empirical results showed that the manufacturer's OL is an antecedent of the relational outcomes achieved in business relationships. Specifically, increased OL in the manufacturer has a direct effect on the main distributor's degree of satisfaction and an indirect effect on his loyalty. It is also confirmed that the manufacturer's OL has a direct effect on the manufacturer's business performance. However, we found that links between OL and satisfaction and OL and loyalty are not changed by market turbulence.     

US and EEC agricultural trade policies: A long-run view of the present conflict

This paper traces post-war agricultural policy in the USA and compares it with the developing policies of the EEC. It examines the reasons for, and the results of, the protectionist policies which have been adopted in each case, and how the present conflict between the two trading blocs were inevitable, due to the foundations laid in the 1950s. The grain sector is used to illustrate the dominant tendencies in US agricultural policies, which include a programme of food aid used as an outlet for US agricultural capacity. The conclusion outlines how the EEC, with its potential for further growth in grain exports, can learn from the US experience in this, and other, aspects of agricultural trade.     

A quantitative analysis of trade policy responses to higher world agricultural commodity prices

The worldwide spike in prices of agricultural commodities in 2007–2008 elevated food security and social stability issues to the forefront, especially in many food-deficit countries. In order to mitigate the global food commodity price pressure on domestic markets, several major exporting and importing countries, mostly developing economies, adopted trade policy changes such as export bans (or raising export restrictions) or reducing import tariffs during the same period. This paper estimates the potential impacts of these policies on the world prices and trade of major agricultural commodities using a set of multi-country, multi-commodity, and partial-equilibrium models. Our findings suggest that over all, the trade policy responses in various countries increased the prices of all agricultural commodities, although the impact on the total net trade varies by commodity. The simulation results show that the overall impact of trade policy distortions on the world rice price is most significant at 24%, followed by wheat (14%) and barley (9%). In general, the poorer food-deficit countries/regions, which have limited power to manipulate their trade policies, experienced higher price increases compared to those major trading countries that adopted policy interventions. Also, the developing countries that are net importers which did not implement trade policy interventions experienced significant welfare losses resulting from interventions implemented by other major trading countries.     

A tale of two tails: Explaining extreme events in financialized agricultural markets

The substantial booms and busts in agricultural prices marked by extreme events across commodities lead to heated debates about the effects of speculative trading on commodity price fluctuations. This study proposes a new approach to understanding extreme events and boom–bust processes in agricultural markets. Using weekly futures data for twelve indexed agricultural commodities during 2006 to 2016, we find that extreme price changes, located in the 10% tails of the distribution, cluster across agricultural markets. We then implement a multinomial logit model to investigate which factors are associated with the propagation of extreme events. Specifically, we disentangle three transmission conduits. (1) The macroeconomic conduit captures the possibility that the synchronized extreme price events are generated by business-cycle driven demand shifts mainly in emerging economies. (2) The financial conduit refers to potential links between extreme returns and the increasing flow of money from financial participants into agricultural futures markets. (3) Finally, the energy conduit accounts for possible spillover effects due to oil price shocks. Our results indicate an important role of managed money positions and oil prices while the real demand channel remains mostly insignificant.     

Urban cassava markets: The impact of fresh root storage

The authors explain how although fresh cassava is important in rural nutrition, its importance in urban areas is limited and declining. In Colombia, the third most important cassava-producing country in Latin America, both the structure of the marketing channel and consumer preferences are considered in explaining this difference. The principal factor limiting urban market volume and demand is identified as the rapid root post-harvest deterioration which necessitates high margins to cover marketing risks. Appropriate storage techniques which overcome this problem are evaluated and their possible positive impact, through reduction of marketing margins, on retail and farmgate prices and on urban consumption is estimated. A strategy for storage technology adoption is discussed.     

National grain policies: The international dimension

Government intervention in the pricing and marketing of grains has led to increased use of restrictive trade practices to preserve domestic price levels and ensure orderly marketing of domestically produced and imported grain. The author examines this relationship between domestic agricultural and trade policies of a selected group of grain importing and exporting countries. The article suggests that, because of the strong link between domestic and trade policies, it will be difficult to reduce trade restrictions in international grain markets in future trade negotiations.     

Distributional effects of agricultural cooperatives in China: Exclusion of smallholders and potential gains on participation

This paper examines the treatment effects of the agricultural cooperative and publicly funded extension services on individual household economy, using data collected by the author from watermelon-producing farm households in rural Nanjing. The cooperative addressed in this study restricts the participation of small-scale farmers, implying that selection into the program must be taken into consideration for an accurate assessment of the treatment effect. The econometric analysis revealed that government extension services have a modest effect on farm income. In contrast, the treatment effect of the agricultural cooperative is robust and substantially large, accounting for nearly 70% of the pre-matching difference. This suggests that the agricultural cooperative system is an important avenue for farmers to improve their economic status. The treatment effect of the agricultural cooperative is highly heterogeneous; the economic benefits arising from the cooperative are significant only for small-scale farms. We can argue that a coexistence of smallholder exclusion and the treatment effect in favor of small-scale farms poses serious challenges to pro-poor agricultural growth in China.     

Linking agricultural policies with obesity and noncommunicable diseases: A new perspective for a globalising world

In light of the shift in policy paradigm in agriculture from state intervention to market liberalisation and globalisation, this paper develops a series of hypotheses on the relationship between agricultural policies and consumer diets. The first hypothesis is that the paradigm shift has led to greater specialisation of production, so changing the ability and incentive for producers to supply certain foods relative to others. Second, the shift has affected farmgate prices (both up and down), so creating opportunities for the industries which purchase farm commodities (the food consuming industries – FCIs) to substitute lower priced ingredients, thereby influencing the nutritional quality and content of foods available in the marketplace. Third, it has increased the ability of the FCIs to “add value” through product innovation and marketing, creating a market characterised by highly differentiated products targeted to individualised preferences, thus increasing the acceptability of a wider variety and quantity of food products.     

Regulating prices in two-sided markets: The waterbed experience in mobile telephony

The distinguishing feature of two-sided markets is that the pricing structure, that is, the relative prices charged to each side, matters. Regulators need to understand and account for the interdependence of prices in both sides. Some interventions that lower the prices on one side can result in higher prices on the other side of such markets. This article reviews the recent literature analyzing this waterbed phenomenon in mobile telephony and draws some more general lessons for policy interventions in two-sided markets.     

Economic environment and agricultural development: The importance of macroeconomic policy

This article explores the ways in which the macroeconomic balance of the economy, and related policies, impinge on agriculture in developing countries, and considers implications for the design of policies. It argues that the extent of macroeconomic balance, and the quality of the policies influencing that balance, to a large extent define the scope for effective agricultural policies. The avoidance of severe balance-of-payments deficits and rapid inflation are seen as a necessary condition for the promotion of agricultural growth. They also have an important influence on the nature and range of agricultural policy options available to governments.     

The impact of agricultural research on productivity and poverty in sub-Saharan Africa

While it is widely recognized that agricultural research is a key driver of broad-based technological change in agriculture that benefits the poor in many different ways, little is known about its aggregate impacts on productivity growth and poverty reduction in sub-Saharan Africa (SSA). Using a polynomial distributed lag structure for agricultural research within a simultaneous system of equations framework, this paper first demonstrates that agricultural research contributes significantly to productivity growth in SSA. Productivity growth is again shown to raise per capita incomes, with income increases finally having significant poverty-reducing effects. With an aggregate rate of return of 55%, the payoffs to agricultural research are also impressive. Agricultural research currently reduces the number of poor by 2.3 million or 0.8% annually. While the actual impacts are not large enough to more than offset the poverty-increasing effects of population growth and environmental degradation, the potential impacts of agricultural research are far greater. Apart from low research investments, SSA faces several constraints outside the research system that hinder realization of potential research benefits. The results show that doubling research investments in SSA would reduce poverty by 9% annually. However, this would not be realized without more efficient extension, credit, and input supply systems.     

Policies to promote cereal intensification in Ethiopia: The search for appropriate public and private roles

Over the past decade, policymakers have been searching for an appropriate blend of public and private sector roles to accelerate the intensification of food staple production, smallholder commercialization, and sustainable market development in sub-Saharan Africa. In Ethiopia, steps taken to liberalize markets in the 1990s and promote fertilizer and seed packages have yet to generate payoffs in terms of higher cereal yields, lower food prices, or reduced dependency on food aid. This raises concern about the performance of the agricultural sector, specifically in terms of the systems for providing improved seed, fertilizer, credit, and extension services. This paper examines the evolving roles of the public and private sectors in intensifying cereal production in Ethiopia. Findings suggest that while Ethiopia has an admirable record of supporting agriculture, its state-led policies has now outlived their usefulness. These findings for Ethiopia offer lessons that are potentially applicable to other sub-Saharan African countries facing similar challenges.     

政府在医药产业集群竞争力提升中的作用

1产业集群定义产业集群作为产业发展的重要方式是一种世界性的经济现象,自20世纪80年代以来在世界范围内日益引起经济学家和各国政府的关注。按照哈佛大学波特（Porter,1998）的定义,产业集群（1ndustrial Clusters）是指在某一特定领域中（通常以一个主导产业为核心）,大量产业联系密切的企业以及相关支撑机构在空间上集聚,并形成强劲、持续竞争优势的现象。     

The role of government in broadband access

This paper discusses the role of governments in broadband. It is divided into five sections. Following an introduction in section one, section two discusses the diffusion of broadband Internet. Section three deals with competition-based and public-goods views on regulation and the corresponding roles and issues for governments. To gain deeper insights into the role of government in broadband, section four analyses market regulation and public activities in furthering broadband deployment in the US, Korea and Europe. These insights are evaluated in relation to the theoretical considerations established in section three. Section five closes with a discussion of our results and some conclusions. It becomes obvious that national broadband strategies benefit from considering both public good and competition-related aspects.

The USA as a developing country: Historical insights into contemporary agricultural development

Students in developed countries preparing for overseas careers in agricultural development may not appreciate the value of studying their own country's agricultural system, especially its history. Three topics chosen from the agricultural development of the USA show the relevance of such studies: disposition of the public lands, programmes to help sharecroppers in the cotton-producing South in the 1930s, and interagency conflicts and institutional factors in the overall agricultural programme of the 1930s. All involve generic issues now being faced by many agriculturally developing nations, and the US record in each offers valuable and sometimes surprising insights into their subtleties.
