The Impact of Seed Policy Reforms and Intellectual Property Rights on Crop Productivity in India

The growth of private investment in developing‐country agriculture, new advances in the biological sciences, and rapid integration of developing countries into the global trading system has heightened interest in the topic of seed market and intellectual property rights’ (IPRs) policies among public policy‐makers, corporate decision‐makers and other actors in the agricultural sector. But there are still unanswered questions about whether emerging and evolving seed policy reforms and IPR regimes in developing countries will contribute to increasing crop productivity and improving food security. This paper attempts to answer some of these questions by focusing specifically on the case of India, the regional leader in implementing seed policy reforms and IPRs in agriculture. Findings indicate that maize and pearl millet yields grew significantly during the last two decades due partly to the combination of (1) public policies that encouraged private investment in India’s seed industry during the 1980s, and (2) biological IPRs conferred by hybridisation that conveniently married the private sector’s need for appropriability with the nation’s need for productivity growth. Although past lessons are not an indication of future success, this convergence of policy solutions and technology opportunities can be replicated for other crops that are vital to India’s food security.     

Policy reform and farmers' wheat allocation in rural China: a case study*

Market‐oriented policy reforms often have important effects on farm‐level grain production and utilisation decisions in developing countries. China's grain farmers are of particular interest because of China's importance in world grain markets and because of China's recent major agricultural policy advances and retrenchments. An empirical evaluation of market liberalisation among farmers located in two provinces in China on farm‐level wheat consumption, market sales and on‐farm storage during 1994 is presented. The results indicate that policymakers should account for such changes in farm household behaviour in designing and assessing the consequence of market liberalisation programs for agricultural sectors in developing countries.     

Do input subsidy programs “crowd in” or “crowd out” commercial market development? Modeling fertilizer demand in a two‐channel marketing system

Many governments in developing countries distribute fertilizer at subsidized prices in an effort to stimulate small farmers' agricultural productivity and food security. Prior fertilizer demand studies have largely failed to account for the effects of government programs on farmers' commercial purchases. Using a double hurdle model and nationally representative rural household panel data in Zambia, we distinguish between these sources and measure the contemporaneous "crowding in" and "crowding out" effects of government input programs on commercial fertilizer sales. Where the private sector is relatively active and average wealth is higher (areas seemingly more likely to be targeted by government programs), results indicate that subsidies have substantially crowded out the private sector, in some cases to the point that such programs could actually lower overall fertilizer use. On the other hand, in poorer areas where the private sector is relatively inactive, subsidies help to generate demand and crowd in private sector retailers. Empirical studies explicitly modeling farmers' fertilizer purchase behavior within a dual marketing framework can provide important insights for agricultural policy discussions in developing countries.     

Biofuels and developing economies: is the timing right?

In this article, we discuss some key aspects of biofuel production in developing countries, and where constraints and tradeoffs are likely to occur. We use the example of two countries, Senegal and India, to highlight some of the issues of cost competitiveness, problems with ensuring stable supply of feedstock as well as critical missing links in the biofuels value chain that pose problems to scaling up national programs in these countries. We discuss the particularly problematic nature of jatropha, as a biodiesel feedstock, and underline some helpful guiding principles that can help country‐level policy. We point to an underlying “duality” between a well‐functioning food system and favorable conditions for agribusiness enterprises, such as biofuels, and the relevance it has to achieving food security goals.     

The Contingent Tariff of the Special Safeguard Mechanism: What Happens When Markets are Imperfectly Competitive?

Contingent tariffs for agri‐food commodities have been proposed as a Special Safeguard Mechanism (SSM) in the Doha Round negotiations by the G33 group of countries as an instrument to control downward spikes in their border prices and/or surges of imports. The objective is to safeguard the livelihood security of farm households in poor countries. To date, most analysis of such tariffs uses stochastic partial equilibrium models with perfect competition. Yet in many markets for such commodities, imperfectly competitive market intermediaries play an important role in determining producers' prices, as do state trading enterprises (STEs). A stochastic partial equilibrium model of a typical importing country situation is specified in which there are either imperfectly competitive domestic intermediaries with a contingent tariff or an STE. The role of these intermediaries in influencing price behaviour and livelihood security in the presence of contingent tariffs alters the conclusion based on models of perfect competition. Using Monte‐Carlo simulation, it is shown that the efficacy of a contingent tariff is substantially reduced as the number of firms declines because increasingly they absorb the tariff, and the procurement price and producer surplus do not increase to the extent that they do under perfect competition.     

Modeling differentiated quality standards in the agri-food sector: the case of meat trade in the enlarged EU

Quality standards play an increasingly important role in international agri-food trade, and their functioning as nontariff barriers to trade is widely discussed. We argue that food quality standards imposed by importing countries are more than just border measures and can have profound effects on the market structure of the exporting industry, thereby significantly influencing the supply response. We develop a stylized oligopoly model that accounts for compliance costs (fixed and variable) and investigate alternative policy options to explore different mechanisms an importing county may use to enhance the quality of its imports. The model explicitly recognizes the coexistence of complying and noncomplying firms, which is a situation often found in low-income countries where a small modern export-oriented segment invests in meeting foreign quality standards. We use the adjustment of the Polish meat sector to the tight EU food quality standards as an empirical example. The simulations show that a subsidy scheme can promote compliance with standards and can contribute to an upgrade of the industry in the exporting country, but its marginal effectiveness is diminishing.     

Trade and agricultural development in the 1980s and the challenges for the 1990s: Asia

Asian developing countries have had varying experiences in trade and agricultural development in the 1980s, attributable in part to their differing stages of economic development and structural characteristics. Other important influences relate to the external economic environment and the policy choices made by their governments not only during the period but also in the preceding decade. The achievements of Asian developing countries under the adverse external conditions of the 1980s are discussed in terms of their macrocconomic and agricultural growth, the commodity structure of agricultural growth, their food production and trade, the expansion and diversification of their agricultural exports, and the policy and nonpolicy factors affecting them. Special attention is given to the role of policy reforms implemented in China and the South Asian countries, following similar policy developments in Northeast and Southeast Asia in the 1960s and 1970s, toward greater openness in their trade regime and increased private-sector participation in the economy. These reforms have contributed to the observed acceleration in gup , agricultural, and export growth in the 1980s. However, macroeconomic imbalances have emerged that threaten the sustainability of economic liberalization in those countries. The major challenges for the 1990s also differ among the Asian developing countries. In the industrially advanced Northeast economies of Taiwan and South Korea, the primary need is to ease the transition of the remaining rural population as farm incomes continue to fall and workers move to industrial and service activities. This challenge has to be addressed in the context of growing external pressure to further open their domestic market for agricultural imports. Among the Southeast and South Asian countries, there is a need to reduce the existing policy biases against agriculture, particularly against export crop production. Moreover, China and the South Asian countries face the additional challenges of continuing to deregulate their trade regime and internal markets, and of promoting macroeconomic stability. Despite the external trend recently toward regionalism, Asian developing countries generally seem committed to an open trading system, on which in fact their past impressive economic performance has been predicated. An important challenge for them in the 1990s is to play an active role in arresting and reversing any protectionist tendencies arising from the formation of regional trading blocs and to support multilateral initiatives such as the Uruguay Round that promote global trade liberalization.     

Trade,policy, and food security

Food insecurity is extensive throughout the world and hunger and malnutrition are expected to remain serious humanitarian and political concerns, both in the short term and for the foreseeable future, particularly in low income developing countries where many rural and urban households are both income and asset poor. In those countries, domestic agricultural production is expected to be especially vulnerable to the impacts of climate change over the next 30 years. Thus international markets for staple agricultural commodities, which have become increasingly important as sources of nutrition for both developing and developed countries over the past 60 years, are likely to become even more important in the future. Free trade policies allow countries to exploit their comparative advantages in economic activity, increasing average per capita incomes, longer term growth rates and a country's capacity to fund social safety nets for the poor. However, many countries abandoned those policies in favor of domestic protections in their efforts to mitigate the effects of short run food crises. The policy challenge is therefore to resolve the tension between optimal long run policies and short run initiatives to address food security concerns.     

Trade Reforms and the Efficiency of Firms in India

In this paper, we analyse the impact of reforms on manufacturing efficiency in India. The sector chosen--the cotton textile industry in India--is a very large employer and exporter and also has considerable historical significance. Its response to the reforms therefore is being watched with some concern. The paper concludes that while there was considerable dispersion in efficiency levels before the reforms, this dispersion has decreased since the reforms. To analyse this, we estimate a best practice frontier for the industry and then measure efficiency as the distance from this frontier. We find that efficiency has increased because the reforms have influenced other factors such as market shares, exports and imports and capital-labour ratios. Our results also indicate that geography--the location of the firm within a state and its proximity to a major urban centre--influences the efficiency levels of firms within it.     

Trade Creation and Diversion Effects of Preferential Trade Associations on Agricultural and Food Trade

Agricultural market distortions remain a major focus of contention in world trade negotiations. Estimates of the effects of liberalising current agricultural trade restrictions indicate an approximately $385 billion increase in global welfare, with the disproportionate share of the benefit being enjoyed by developing countries. In response to difficulties in adopting agricultural trade reforms, individual groups of countries have formed multiple bilateral and regional preferential trade agreements (PTA) to enhance trade among members. Few sectoral analyses exist of the effects on agricultural and food product trade of PTAs. This research uses a gravity model to isolate the effects of various PTAs on both intra‐ and extra‐bloc agricultural and food product trade for three time periods: 1995, 2000 and 2004. Findings strongly support PTA benefits in terms of increased intra‐bloc trade in both sectors. The findings also generally support trade creation in agricultural products. PTA membership was also associated with food trade creation in most cases, although diversion was observed for several associations composed primarily of developing countries.     

Enhancing Access to the Global Food Manufacturing Value Chain: The Role of a Food Safety Technical Regulation in Ghana

Demonstrating compliance with food safety requirements of the global food economy is a prerequisite for access. This article presents an overview of the governance within global value chains and their impact on the prospects of developing countries accessing and participating in the global food manufacturing value chain. Based on fieldwork undertaken in Ghana, the article investigates the issues that hinder compliance of the Ghanaian food manufacturing sector with the basic requirements of food safety and investigates the potential role of a technical regulation in enhancing compliance, and therefore participation, in the global food manufacturing economy.     

The linkage between the U.S. ethanol market and developing countries’ maize prices: a panel SVAR analysis

The major expansion of U.S. ethanol production raises concerns about the potential detrimental impacts on developing countries’ agricultural prices, farm income, and food security. To assess the sensitivity of maize prices to ethanol production, this study explores the linkage between the U.S. ethanol market and developing countries’ maize prices. The econometric approach, based on a panel structural vector autoregression model, captures market interdependencies and the likelihood that developing countries’ responses are both heterogeneous and dynamic. The results indicate that the U.S. ethanol market's impacts on maize prices in developing countries are heterogeneous and that coastal countries are more susceptible to U.S. economic shocks. The estimates also suggest that countries more dependent on food imports and/or receiving U.S. food aid are at a higher risk of being affected by such shocks. Overall, the results indicate that those countries with the greatest sensitivity and exposure to global agricultural commodity markets could benefit from domestic policies and international assistance, which reduce their exposure to impacts from the U.S. maize market.     

The Effects of Maize Market and Policy Reforms on Price Discovery and Competitiveness in Zimbabwe, 1991–1997

Abstract

Maize is Zimbabwe's staple food. An adequate supply of maize is essential to food security and domestic stability. A series of droughts and government mismanagement of the economy led to a maize production and food security problem in the 1980s. Zimbabwe's maize marketing system was transformed dramatically from a government monopoly to a competitive market system in which prices are determined by market forces in the 1990s. This paper examines the steps that Zimbabwe took towards maize market reform and the benefits of that reform. The movement to a competitive market led to formation of a commodity exchange to improve price discovery and increase price transparency. De-regulation has increased entry and competitiveness from new private sector hammer millers and traders. Farmers, millers, and traders face new profit opportunities and new price and financial risks that have increased management responsibilities. Consumers enjoy lower cost maize meal products and more convenient service. The benefits of the 1991–1997 reforms indicate what could be achieved in the long run if prices are determined by the market, rather than by the government.     

Enhancing food security in South Sudan: the role of markets and regional trade

South Sudan faces serious problems of food insecurity due to low levels of domestic food production, periodic droughts, widespread poverty, and since late 2013, renewed armed conflict. This article explores market price behavior using cointegration analysis and estimates the effects of production and trade shocks through multimarket model simulations. We show that market prices in the capital city, Juba, of both maize and sorghum are cointegrated with import parity prices of these cereals sourced from Uganda, consistent with observed trade flows. Model simulations, using econometrically estimated demand parameters, suggest that private sector imports of maize and wheat would greatly mitigate the potential fall in consumption in the case of a decline in domestic cereal production. Other simulations indicate that if total imports of cereals are reduced by one‐third (still more than two times the levels of food aid in 2013) because of disruptions to private market flows, domestic prices of cereals could rise by 45% or more. The article concludes that whatever measures are taken involving national food security reserves, it is crucial that government policy serves to maintain incentives for private sector imports to avoid destabilizing market supplies, domestic prices, and ultimately, food consumption of the poor.     

TRADE REFORM AND THE PROSPECTS FOR PROCESSED FOOD EXPORTS FROM DEVELOPING COUNTRIES

This paper draws attention to the relative neglect of the consequences of barriers to processed food exports from developing countries in the literature examining the effects on these countries of agricultural trade liberalisation. These barriers are of three kinds: trade policy barriers; differing health, food safety and environmental standards; and, barriers arising from the evolving market structure in food processing and distribution in developed country markets. The paper discusses the likely significance of the gains to developing countries from reduction of tariffs on processed food commodities and examines the consequences of the EU single market programme for developing country food exports.     

The effect of barge and ocean freight price volatility in international grain markets

Short‐run responses of export and domestic shares of total agricultural output to changes in stocks of domestic savings (SAV), development assistance (ODA), private foreign commercial capital (PFX) and other variables is investigated. A profit function approach is used. Time series data for 19 sub‐Saharan African countries are pooled into three panels using similarities in changes in economic policy regime. Statistical evidence suggests that for the panel of countries that were undertaking liberalized economic reforms, the slope coefficients of some of the variables in the models have changed significantly between 1970–1980 and 1981–1993. For the 1981–1993 period, the impacts of ODA, PFX and SAV on export and domestic shares were different for this panel. The effect of increases in agricultural labor was different across the three panels. There is also evidence that productivity growth in the export agriculture sub‐sector is negative in all the groups. It is recommended that to halt the decline in export share of agricultural output in the group of countries that have undertaken substantial improvements in economic policy environment, efforts must be made to reduce the negative impact of domestic savings and agricultural labor, while at the same time working to reduce the bias of development assistance against food security.     

Sudan's agricultural sector diversity and policy reforms with reference to devaluation and food self‐sufficiency

Abstract

Sudan's agricultural sector is characterized by division into three structurally and institutionally distinct sub‐sectors. This paper discusses the likely impact of exchange rate reform on the structure of incentives, relative competitiveness and food self‐sufficiency, both intersectorally and intrasectorally. Employing domestic resource cost analysis and a simple framework for calculating expected net revenue for staple foodgrain, results indicate that policy reforms, particularly devaluation, appear to have affected the various sub‐sectors differently, and overall devaluation has met inadequately the challenge of sustaining a viable agriculture. The pursuit of food self‐sufficiency strategy may be explained in terms of expected net revenues and risk aversion; both are largely related to policy reforms and efficiency of the marketing system.     

高水平开放下我国粮食安全的非传统挑战及政策转型

当前我国粮食安全已经迈入新的发展阶段,一方面国内的粮食安全保障程度处于历史最佳时期,另一方面农业对外开放也处于全球领先水平,国际粮食市场日益成为保障国内粮食供应的重要组成部分,但同时也为维护国家粮食安全带来了一系列前所未有的非传统压力和挑战,包括以高产量、高进口、高库存为代表的过度进口冲击粮食自给率的“想挡挡不住”、粮食生产国内支持政策与WTO国际规则存在一致性纷争的“想做不能做”、世界市场风险与贸易动荡加剧国际粮源不确定性的“想进有风险”,以及在全球粮食安全治理体系中的作用仍待加强的“想为难作为”。在新一轮高水平开放下,亟需转型思维、构建“三元平衡”的开放型国家粮食安全战略保障体系,积极推动我国粮食安全目标由产量导向向竞争力导向转型,农业国内支持政策设计由国内外分轨向内外对接转型,外部粮食市场与资源利用由单方自主开合向主动风险管控转型,主动参与全球粮食安全治理与制度变革,全面升级对内与对外的粮食安全治理能力。     

玉米补贴政策调整对宏观经济的影响*——基于CGE模型的分析

[目的]寻求玉米补贴政策改变对宏观经济和粮食安全的影响,并厘清影响的幅度,寻求玉米政策调整的合理方向。[方法]对现有的中国可计算一般均衡模型进行了改进,引入库存积累、临时存储库存入市、库存销售和顺价机制,加入玉米实物量模块。通过设定政策模拟情景,运用2012年中国投入产出表、农业农村部、中国统计年鉴等资料将数据库进行了更新,对农业部门的玉米补贴减少政策的影响进行了模拟。[结果]降低玉米种植补贴后,玉米种植面积和产量都将改变。短期内,补贴减少将减少财政压力。中长期来看,减少补贴政策将对GDP产生负面影响,且远大于财政补贴减少的幅度。而玉米占经济量的份额很小,玉米相关行业的变化,对宏观经济的影响较弱。[结论]实现去库存、调结构、降低种植面积,进行市场化决策,就要坚持玉米价格市场化改革,注重政策的时效性和针对性,加强信息监测预警。提高政府对玉米市场的宏观调控能力,实施多策并举的政策,有助于实现宏观经济改善,保持农业生产持续健康良好运行。
