China, with the largest population in the world, has always been concerned about its food security. Recently, rapid economic growth in China has led to the disappearance of absolute hunger, but an increase in food consumption and environmental problems still threaten the maintenance of China’s food security. This study aims to analyze the effects of main factors on Chinese food security and investigates the inverted U-shaped relationship using the extended environmental Kuznets curve (EKC) on 1980-2013 time series data. The results found to be robust across different methods including vector autoregressive (VAR) model, impulse response function (IRF), and Granger causality test. The main findings of this study are (1) an inverted U-shaped relationship exists between Chinese food security and main factors (economic growth, agricultural trade, and CO2), (2) there is a positive impact of economic growth on food security but negative impact of agricultural trade and CO2 on food security with respect to the linear relationship, and (3) there is Granger causality between the main factors and food security. Based on the analysis, this study suggests that the Chinese government needs to continue investment in agriculture, environmental regulations, and the expansion of domestic agricultural production base to improve its food security.
中国是世界上人口最多的国家,始终关注粮食安全问题。近年来,中国经济的快速增长使绝对饥饿现象消失,但粮食消费的增加和环境问题仍然威胁着中国粮食安全的维持。本文利用扩展环境库兹涅茨曲线(EKC)对1980-2013年的时间序列数据进行分析,分析主要影响因素对中国粮食安全的影响,并考察其倒u型关系。通过向量自回归(VAR)模型、脉冲响应函数(IRF)和格兰杰因果关系检验,结果均具有鲁棒性。研究发现:(1)中国粮食安全与主要因素(经济增长、农产品贸易和二氧化碳)呈倒u型关系;(2)经济增长对粮食安全具有正影响,农产品贸易和二氧化碳对粮食安全具有负影响,呈线性关系;(3)主要因素与粮食安全之间存在格兰杰因果关系。在此基础上,本文建议中国政府应继续加大农业投资力度,加强环境监管,扩大国内农业生产基地,以提高粮食安全水平。

This paper explores how New Zealand should address agricultural greenhouse gas emissions: methane and nitrous oxide. The starting point is the internationally agreed-upon goal of limiting global warming to below two degrees, and New Zealand’s commitment to contribute its ‘fair share’ to the international climate-change mitigation effort. The report focuses on the role of mitigating biological agricultural emissions within that, and how New Zealand could most cost-effectively mitigate its own emissions and contribute to the mitigation of agricultural emissions abroad. This paper complements a partner paper (Hollis et al 2015) that discusses the science relating to agricultural greenhouse gases.
本文探讨了新西兰应该如何解决农业温室气体排放:甲烷和一氧化二氮。起点是国际社会商定的将全球变暖控制在2摄氏度以下的目标,以及新西兰承诺为国际减缓气候变化的努力贡献自己的“公平份额”。该报告侧重于减少农业生物排放在其中的作用,以及新西兰如何能够以最具成本效益的方式减少本国的排放,并为减少国外的农业排放作出贡献。本文补充了一篇讨论农业温室气体相关科学的合作论文(Hollis et al . 2015)。

Policy Space in Agriculture Under the WTO Rules on Domestic Support WTO国内支持规则下的农业政策空间
Pub Date : 2015-07-28 DOI: 10.2139/SSRN.2659406
L. Brink
A concept of policy space is formulated under the domestic support rules of the WTO Agreement on Agriculture. This policy space is dyadic, comprising two kinds of space: exemption space and limited space. The two kinds are available differently for different countries. Exemption space derives from the entitlement to exempt policies that meet given criteria from those policies under which support counts against the country’s limit(s), i.e., exemption space allows limitless support. The criteria are those of Annex 2, Article 6.2 and Article 6.5 of the Agreement (green, development and blue boxes). Limited space derives from the entitlement to provide support under non-exempt policies up to the country’s limit(s). For most countries the limits are the de minimis levels calculated from the value of production of each product and of agriculture as whole, using the country’s de minimis percentage. For 32 countries (15 developed and 17 developing) the limit is the Bound Total Aggregate Measurement of Support (BTAMS) and the de minimis levels are thresholds above which support counts against the limit. Some acquisition of foodstuffs at administered prices is subject to special rules, now subject to negotiations with implications for both exemption space and limited space and the interaction between these two kinds of space. The Agreement’s criteria are reviewed to interpret the factors determining a country’s exemption space. In determining limited space, the centrality of a country’s values of production is illustrated by tracking limited space from 1995 to 2012 for the EU, the US, India and China under assumptions of perfect management of maximum support. China’s rapidly rising values of production have generated limited space that now greatly exceeds that of the EU. The US limited space has been rising but India’s limited space is growing faster and approaches the US level. In recent years these four countries have used only a small part of their limited space. As values of production rise in individual countries and in the world, the relative importance of BTAMS as a component of limited space declines since it stays fixed in nominal terms. The amount and the share of non-exempt support that can be accommodated within the de minimis provisions are thus increasing for individual countries and in total for the world. Some countries with declining values of production in agriculture are the exceptions, e.g., Japan. The different entitlement of different countries to limitless exemption space, in combination with limited space growing faster in some countries than in others, means that the picture of countries’ policy space for domestic support to agricultural producers is rapidly changing from the picture when the Doha negotiations started.
根据WTO《农业协定》的国内支持规则,提出了政策空间的概念。这种政策空间是二元的,包括豁免空间和限制空间两种。这两种在不同的国家有不同的规定。豁免空间源于对符合特定标准的政策的豁免权利,根据这些政策,支持将计入国家的限制,即豁免空间允许无限制的支持。标准为协议附件2第6.2条和第6.5条(绿色、发展和蓝色方框)中的标准。有限的空间源于在非豁免政策下提供不超过国家限额的支持的权利。对大多数国家来说,限额是根据每个产品的产值和整个农业的产值,利用该国的最低百分比计算出的最低水平。对于32个国家(15个发达国家和17个发展中国家),限额是支持的绑定总汇总测量(BTAMS),最低限额是超过该限额的支持计数的阈值。以管理价格收购的一些食品受特殊规则的约束,现在需要就豁免空间和限制空间的影响以及这两种空间之间的相互作用进行谈判。对协定的标准进行审查,以解释决定一国豁免空间的因素。在确定有限空间时,可以通过追踪1995年至2012年欧盟、美国、印度和中国的有限空间,在最大支持的完美管理假设下,来说明一个国家生产价值的中心地位。中国生产价值的迅速上升产生了有限的空间,目前已大大超过欧盟。美国有限的空间一直在增加,但印度有限的空间增长得更快,接近美国的水平。近年来,这四个国家只利用了其有限空间的一小部分。随着个别国家和世界的生产价值上升,BTAMS作为有限空间组成部分的相对重要性下降,因为它在名义上保持固定。因此,在最低限度规定范围内可以容纳的非豁免支助的数额和份额对个别国家和对全世界总的来说都在增加。一些农业产值下降的国家是例外,例如日本。不同国家享有无限豁免空间的权利不同,加上有限的豁免空间在一些国家比其他国家增长得更快,这意味着各国国内支持农业生产者的政策空间与多哈谈判开始时的情况正在迅速发生变化。

A Value Chain Approach to Measuring Distortions to Incentives and Food Policy Effects (with Application to Pakistan's Grain Policy) 衡量激励扭曲和粮食政策影响的价值链方法(应用于巴基斯坦的粮食政策)
Pub Date : 2015-04-01 DOI: 10.2139/ssrn.2595156

We develop an extended Nominal Rate of Assistance (NRA) methodology to disentangle the welfare impacts of policies for various interest groups along the value chain (to disaggregate effects within the “producer” and “consumer” umbrellas). We apply our value chain NRA methodology to the case of Pakistan’s price and trade policy. We analyse the welfare implications for various agents in the wheat-flour value chain from 2000 to 2013, a period characterized by major global price volatility and by regular adjustments of domestic policies. We find that the wheat price policy has generally benefitted flour consumers and wheat traders at the expense of wheat farmers and to a lesser extent flour millers. Our findings illustrate that the welfare implications of policies can be quite different within the “producer” and “consumer” umbrellas, which has potentially important implications for economic and political economy analyses and for the design of policies that aim to target the poorest groups along value chains.
我们开发了一种扩展的名义援助率(NRA)方法,以理清政策对价值链上各种利益集团的福利影响(在“生产者”和“消费者”伞内分解影响)。我们将价值链NRA方法应用于巴基斯坦的价格和贸易政策。我们分析了2000年至2013年小麦面粉价值链中各主体的福利影响,这一时期的特点是全球价格大幅波动,国内政策定期调整。我们发现,小麦价格政策总体上有利于面粉消费者和小麦贸易商,而牺牲了麦农和面粉加工商的利益。我们的研究结果表明,在“生产者”和“消费者”伞下,政策对福利的影响可能大不相同,这对经济和政治经济分析以及针对价值链上最贫困群体的政策设计具有潜在的重要意义。

The Effects of IBGE and USDA Announcements on BM&FBOVESPA Soybean and Corn Futures Prices IBGE和USDA公告对BM&FBOVESPA大豆和玉米期货价格的影响
Pub Date : 2015-03-09 DOI: 10.2139/ssrn.2576780

This paper analyzes the impact of USDA and IBGE crop forecast announcements in the Brazilian corn and soybean futures market. Futures prices were obtained from BM&FBOVESPA from 2009 to 2014 and announcements days were collected from IBGE and USDA historical reports. Expected value of absolute price changes (EABS) of four days before and four days after were calculated. Univariate and multivariate tests were performed to assess if the information on the reports affected prices. Results using EABS show that the high illiquidity of soybean March contract does not allow prices to reflect information and corn futures prices are influenced only by USDA announcements. Results also show that Brazilian market participant expectations tend to overestimate both USDA and IBGE forecasts. The conclusion of this work is that USDA announcements bring new information only for corn futures market and the lack of liquidity in the market might deteriorate the information transfer capacity of corn and soybean futures prices
本文分析了美国农业部和IBGE的作物预测公告对巴西玉米和大豆期货市场的影响。2009年至2014年的期货价格来自BM&FBOVESPA,公告日期来自IBGE和USDA历史报告。计算前后4天的绝对价格变动期望值(EABS)。进行了单变量和多变量测试,以评估报告中的信息是否影响价格。使用EABS的结果表明,大豆3月合约的高非流动性不允许价格反映信息,玉米期货价格仅受美国农业部公告的影响。结果还表明,巴西市场参与者的预期往往高估了美国农业部和巴西农业和农业研究所的预测。本研究的结论是,美国农业部的公告只会给玉米期货市场带来新的信息,市场流动性不足可能会恶化玉米和大豆期货价格的信息传递能力

Rural Policies, Price Change and Poverty in Tanzania: An Agricultural Household Model-Based Assessment 坦桑尼亚农村政策、价格变化与贫困:基于农户模型的评估

Exogenous shocks to farmers’ consumption, production and labour market decisions are rarely considered accurately. For farm households, under labour market imperfections, such decisions are often interlinked. This calls for non-separable agricultural household models. According to this framework, second-order (or behavioural) effects include a direct (i.e., supply or demand reactions due to an exogenous shock) and an indirect (i.e., supply or demand adjustments to the endogenous variations in the shadow wage generated by the exogenous shock) component. Under large price changes or following structural interventions, such as those concerning land redistribution or mechanization practices, neglecting such second-order effects on consumption and production can bias the final impact on household welfare. The main objective of this study is thus to develop a robust and comprehensive tool to evaluate the effect on household welfare of different agricultural policies in Tanzania and food price changes. A two-stage estimation strategy is adopted: the shadow price of labour is first estimated and then used to estimate production and demand systems as well as labour market functions. These models are subsequently used to simulate the effect on household welfare of a hypothetical 40% increase in the price of cereals and other crops and a hypothetical 10% increase in the hectares of arable land and in the use of ox-ploughs.

对农民消费、生产和劳动力市场决策的外生冲击很少得到准确考虑。对于农户来说,在劳动力市场不完善的情况下,这些决定往往是相互关联的。这就需要不可分离的农业家庭模式。根据这一框架,二阶(或行为)效应包括直接(即,由于外生冲击引起的供给或需求反应)和间接(即,供给或需求对外生冲击产生的影子工资内生变化的调整)成分。在价格大幅变化或结构性干预之后,如涉及土地再分配或机械化做法的干预,忽视这种对消费和生产的二级影响可能会影响对家庭福利的最终影响。因此,本研究的主要目标是开发一个强大而全面的工具,以评估坦桑尼亚不同农业政策和粮食价格变化对家庭福利的影响。采用两阶段估计策略:首先估计劳动力的影子价格,然后用于估计生产和需求系统以及劳动力市场功能。这些模型随后被用来模拟假设谷物和其他作物价格上涨40%、假设耕地面积和牛犁使用量增加10%对家庭福利的影响。最后与采用可分离模型的情况进行了比较。

Food Inflation in India: The Role for Monetary Policy 印度食品通胀:货币政策的作用

Indian food and fuel inflation has remained high for several years, and second-round effects on core inflation are estimated to be large. This paper estimates the size of second-round effects using an estimated reduced-form general equilibrium model of the Indian economy, which incorporates pass-through from headline inflation to core inflation. The results indicate that India's inflation is highly inertial and persistent. Due to second-round effects, the gap between headline inflation and core inflation decreases by about three fourths within one year as core inflation catches up with headline inflation. Large second-round effects stem from several factors, such as the high share of food in household expenditure and the role of food inflation in informing inflation expectations and wage setting. Analysis suggests that in order to durably reduce the current high inflation, the monetary policy stance needs to remain tight for a considerable length of time. In addition, progress on structural reforms to raise potential growth is critical to reduce the burden on monetary policy.
印度食品和燃料的通货膨胀已经持续了好几年,对核心通货膨胀的第二轮影响估计很大。本文使用估计的印度经济的简化一般均衡模型来估计第二轮效应的大小,其中包括从总体通货膨胀到核心通货膨胀的传递。结果表明,印度的通货膨胀是高度惯性和持续的。由于第二轮效应,随着核心通胀赶上总体通胀,总体通胀与核心通胀之间的差距在一年内缩小了约四分之三。较大的第二轮效应源于几个因素,例如食品在家庭支出中的高份额以及食品通胀在通知通胀预期和工资设定方面的作用。分析认为,为了持久地降低当前的高通胀,货币政策立场需要在相当长的一段时间内保持紧缩。此外,在提高潜在增长率的结构性改革方面取得进展,对于减轻货币政策负担至关重要。
