Pricing to market behaviour of India's high value agri‐food exporters: an empirical analysis of major destination markets

The pricing behaviour of India's high value agricultural and food exporters in their major destination markets is examined using a pricing‐to‐market (PTM) model for noncompetitive and exchange rate related pricing behaviour. The analysis was undertaken in a context where India is showing high commodity concentration in agricultural trade. The econometric analysis employed is panel corrected standard errors (PCSE) estimation technique. The results indicated evidence of a greater degree of imperfect competition either through price discrimination across destinations or through imperfect exchange rate pass‐through. The analysis of exchange rate effects showed that the local currency price stabilization by the Indian exporters were more prominent than the amplification of exchange rates. The analysis of the asymmetric effects of exchange rates on export prices showed that in most cases the depreciation of Indian rupee had a greater impact than the appreciation. Moreover the results showed that the exchange rate pass‐through is sensitive to the kind of exchange rate index utilised. In our analysis we found that the commodity specific exchange rate better predicts the pricing to market behaviour in most cases.     

Aggregate measures of support in the Uruguay round: Application to the EC cereals sector

Abstract

This paper examines the use of aggregate measures of support (AMSs) in the proposals for the long‐term reform of agricultural support tabled by the major participants in the Uruguay Round. The USA, the Cairns Group (CG) and the EC have proposed measures based on the OECD's Producer Subsidy Equivalent (PSE), adjusted to take account of only the most trade‐distorting policies, and using a fixed reference price to calculate the extent of market price support. If the proposed ‘adjusted PSEs’ are used, the reductions in internal support levels in the EC cereals sector from the base periods to 1995 range from 8 billion ECU under the US proposal to 4.5 billion ECU under the EC proposal. The resulting ‘producer prices’ would be almost 20% higher under the EC proposal than under the other two. In terms of percentage PSEs, support to farmers would be around 20 to 25 percentage points below present levels under the US and CG proposals and around 18 percentage points lower under the EC's plan.     

Wheat breeding,productivity and slow variety change: evidence from the Punjab of India after the Green Revolution*

Variety change and genetic diversity are important means of combating crop losses from pests and diseases in modern agricultural systems. Since the Green Revolution, genetic diversity among wheat varieties released in India has increased but variety change on farms continues to be slow. In this article, we define and summarise indices of variety change and genetic diversity for the wheat varieties released and grown in Indian Punjab during the post‐Green Revolution period. We evaluate the effect of each index on technical efficiency with a Cobb‐Douglas yield model after testing for exogeneity. Findings support the hypothesis that slow variety change has offset the positive productivity effects of diversifying the genetic base in wheat breeding during the post‐Green Revolution period. Policies that speed the rate of variety change and contribute to a more equitable spatial distribution of modern varieties could support wheat productivity in the Punjab of India, reinforcing plant breeding successes.     

How sensitive is U.S. agricultural trade to the bilateral exchange rate? Evidence from bulk,intermediate, and consumer‐oriented products

This article examines the dynamic effects of changes in bilateral exchange rates on changes in bilateral trade of bulk, intermediate, and consumer‐oriented agricultural products between the United States and its 10 major trading partners. We find that, for consumer‐oriented products, U.S. exports are highly sensitive to bilateral exchange rates in both the short and long run, while U.S. imports are mostly responsive only in the short run. For bulk products, on the other hand, U.S. exports and imports are relatively insensitive to exchange rate changes in both the short and long run. For intermediate products, exports and imports are responsive to exchange rate changes in the short run, but not in the long run. It is also found that income of the United States and its trading partners has a significant effect on U.S. exports and imports of the three types of agricultural products in both the short and long run.     

Linking of U.S. monetary policy and exchange rates to world soybean markets

The linkage between macroeconomic policies and agricultural commodity trade has become an important research issue of agricultural economists. This paper investigates the macroeconomic linkage of soybean trade competition between the exporting countries of the United States, Brazil, and Argentina in the EC-12 and Japan import markets. It is argued that U.S. monetary growth may have important impacts on the competitive position of U.S. soybean exports through exchange rates. Two relationships are investigated: (a) the effects of U.S. monetary growth on the agricultural trade weighted exchange rates, and (b) the responsiveness of agricultural commodity prices and U.S. exports to exchange rate movements. Results indicate that a weak dollar increases imports of soybeans and soymeal significantly which serves to increase the equilibrium world price and increase both U.S. and Brazil/Argentina exports in the long run. However, during periods of more expansionary U.S. monetary policy there is little evidence of significant increases in market share position for U.S. soybeans and soymeal in world markets.     

Economy-wide reform and agricultural recovery: Observations of economic Darwinism among transition economies

The fitness of an economy and its prospects for continued prosperity will be measured and determined by its robustness and its ability to adapt to changing circumstances. Some countries in transition are adapting much more easily than others to rapid changes in the orientation of their economy, the common objective of which is to achieve economic growth through the adoption of a range of characteristics generally associated with a market economy. Economic growth does not have to be very fast, but it must be efficient and sustainable. Policy adjustments must address political economy concerns, while seeking to achieve macroeconomic equilibrium and price stabilization, competitiveness, efficiency and flexibility, and the protection of the living standards of the most vulnerable population The process of agricultural sector reform will be determined both by economy-wide policies and sector-specific policies. This paper first outlines a taxonomy of the objectives of agricultural sector reform, and then discusses the way in which indirect price interventions (specifically exchange rate and interest rate policies, expansive fiscal policies and industrial protection policies), influence agricultural growth. Lessons of experience drawn from the UNDP/World Bank Trade Expansion Program structural and sectoral adjustment operations in Poland, and the cases of New Zealand and Chile are employed to illustrate not only the constraints that countries face in this regard, but also in identifying targets for further action. The third section presents what is called the architecture of incentives for agriculture'. In defining a strategy of agricultural sector reform, experience has shown that a structure of incentives can be developed that creates an environment ripe for agricultural growth-incentives relating, for example, to taxation, prices, foreign investment, privatization and demonopolization, decentralization and institutional reform. Special considerations that will require additional attention by policy-makers outside of this structure include the maintenance of GATT-legal principles in trade policies, issues relating to tariffication (including concerns about price risk management, food supply, and the role of food aid), input and credit subsidies as a means to correct for market failures, and the role of regional trading blocks in world trade.     

Pass-through of exchange rates and tariffs in Greek-US tobacco trade

The paper examines the extent to which exchange rate and unit tariff changes are passed-through in US import prices ot unmanufactured Greek oriental tobacco. The results indicate partial pass-through of exchange rates and tariffs. Exchange rate pass-through is about 0.272 and tariff pass-through about 0.185. One possible reason for the partial pass-through is oligopoly in tobacco exporting. Oligopoly would imply that depreciation of the drachma relative to the US dollar benefits tobacco exporters operating in Greece. A second possible reason is a possible correlation between exchange rates premiums paid to tobacco exporters in previous agricultural policies. An important implication ot this possible correlation is that Greek tobacco prices may be more sensitive lo exchange rate changes under the current agricultural policy.     

Economic development, institutional change, and the political economy of agricultural protection An econometric study of Belgium since the 19th century

This empirical study uses 100 years of annual data on 11 agricultural commodities from Belgium to measure the impact of structural changes coinciding with economic development and changes in political institutions on agricultural protection. The analysis shows that changes in agricultural protection are caused by a combination of factors. Governments have increased protection and support to farmers when world market prices for their commodities fell, and vice versa, offsetting market effects on producer incomes. Other economic determinants were the share of the commodities in total consumer expenditures (negative effect) and in total output of the economy (positive effect). With Belgium a small economy, there was no impact of the trade position. Changes in political institutions have affected agricultural protection. Democratic reforms which induced a significant shift in the political balance towards agricultural interests, such as the introduction of the one‐man‐one‐vote system, led to an increase in agricultural protection. The integration of Belgian agricultural policies in the Common Agricultural Policy in 1968 coincided with an increase in protection, ceteris paribus. Both institutional factors, related to changes in access to and information about the decision‐making at the EU level, and structural changes in the agricultural and food economy may explain this effect.     

Exchange Rate Uncertainty and Agricultural Trade

Using a sample of bilateral trade flows across ten developed countries between 1974 and 1995, this article explores the effect of exchange rate uncertainty on the growth of agricultural trade as compared to other sectors. Based on a gravity model that controls for other factors likely to determine bilateral trade, the results show that real exchange rate uncertainty has had a significant negative effect on agricultural trade over this period. Moreover, the negative impact of uncertainty on agricultural trade has been more significant compared to other sectors.     

Does the Exchange Rate Matter to Agricultural Bilateral Trade between Canada and the U.S.?

This study examines the effects of the Canada–U.S. exchange rate on bilateral trade of agricultural goods between the two countries and on U.S. farm income. Special attention is given to agricultural trade between the two countries under the Canada–U.S. Free Trade Agreement (CUSTA). This study utilizes two time series models: the vector error correction model (VECM) and the vector moving average model (VMA) with quarterly time series data from 1983 to 2000. It is found that the exchange rate has a significant impact on U.S. agricultural trade with Canada, but the impact on U.S. agricultural price and income is insignificant. The exchange rate between the two currencies is found to be weakly exogenous in the U.S. agricultural sector, which answers a fundamental question about the role of the exchange rate in Canada–U.S. bilateral trade for agricultural products. In addition, the results point to a significant, though minimal, effect on bilateral trade due to CUSTA.     

Do rural public works influence agricultural wages? The case of the employment guarantee scheme in India

Abstract

Since growth alone will not make a significant difference to agricultural wages in an oligopsonistic labour market, a case is made out for special employment programmes along the lines of the Employment Guarantee Scheme (EGS) in the Indian state of Maharashtra. The EGS has a substantial effect on agricultural wages—especially long‐term. Diminution of income supplementation through this scheme, following a sharp reduction in the share of poor participants, was thus partly offset by higher agricultural wages. To the extent that this income diminution reflected exclusion of the poor from the EGS because of deficiencies in its design and implementation, prompt remedial action would enhance significantly their bargaining power vis‐a‐vis that of large landholders.     

Agent‐based Modelling of Climate Adaptation and Mitigation Options in Agriculture

Computer simulation models can provide valuable insights for climate‐related analysis and help streamline policy interventions for improved adaptation and mitigation in agriculture. Computable general equilibrium (CGE) and partial equilibrium (PE) models are currently being expanded to include land‐use change and energy markets so that the effects of various policy measures on agricultural production can be assessed. Agent‐based modelling (ABM) or multi‐agent systems (MAS) have been suggested as a complementary tool for assessing farmer responses to climate change in agriculture and how these are affected by policies. MAS applied to agricultural systems draw on techniques used for Recursive Farm Programming, but include models of all individual farms, their spatial interactions and the natural environment. In this article, we discuss the specific insights MAS provide for developing robust policies and land‐use strategies in response to climate change. We show that MAS are well‐suited for uncertainty analysis and can thereby complement existing simulation approaches to advance the understanding and implementation of effective climate‐related policies in agriculture.     

Impact and implications of price policy and land degradation on agricultural growth in developing countries

In many developing countries, a high proportion of the population resides and works in rural areas. Agriculture is the dominant sector in rural areas and has the greatest concentration of poverty: landless workers, small tenant farmers, and small farm owners. Thus, any development strategy that is directed towards increasing employment and alleviating a country's hunger must concentrate on sustainable agricultural growth. Historically, economic development in most countries has been based on exploitation of natural resources, particularly land resources. Soil erosion and land degradation have been serious worldwide. Due to reasons such as high population pressure on land and limited fossil energy supplies, land degradation is generally more serious in the developing world. Empirical studies show that soil erosion and degradation of agricultural land not only decrease the land productivity but they can also result in major downstream or off-site damage which may be several times that of on-site damage. In promoting industrialization, governments of many developing countries adopt a package of price and other policies that reduce agricultural production incentives and encourage a flow of resources out of agriculture. Increasing evidence shows that these policies cause a substantial efficiency or social welfare loss, and a great loss in foreign exchange earnings. In addition, a World Bank study on the effect of price distortions on economic growth rates concluded that neither rich resource endowments, nor a high stage of economic development, nor privatization are able to make up the adverse effects caused by high price distortions. This analysis is primarily concerned with identifying the factors that determine the agricultural production growth rate and in testing the effects these factors have on agricultural growth in developing countries. Specifically, this study involves statistical estimation of an aggregate agricultural growth function based on cross-country data for 28 developing countries. Special attention is devoted to land degradation and agricultural pricing policy, and to the policy implications resulting from the effects these variables have on agricultural and food production growth. The overall results of this study show that price distortions in the economy and land degradation had statistically significant negative impacts while the change in arable and permanent land was positively related to the growth of agricultural production and food production in 28 developing countries from 1971 to 1980. These results emphasize the importance of ‘getting prices right’ and implementation of sustainable land and water management practices if future growth in food and agricultural output is to be realized and sustained in developing countries.     

Land use dynamics in the central highlands of Vietnam: a spatial model combining village survey data with satellite imagery interpretation

The paper investigates geo‐physical, agro‐ecological, and socio‐economic determinants of past land use change in two districts of Dak Lak province in the Central Highlands of Vietnam and assesses the influence of rural development policies on land cover change. Landsat satellite images from the years 1975, 1992 and 2000 are interpreted to detect land cover in two time periods. A survey in randomly selected villages provides primary recall data on socio‐economic and policy variables hypothesised to influence land use change. Secondary data on rainfall, soil suitability, and topography was obtained from meteorological stations and from a digital soil map and digital elevation model. All data were spatially referenced using geographic information systems (GIS) software. A reduced‐form, multinomial logit model is used to estimate the influence of hypothesised determinants on land use and the probabilities that a certain pixel has one of five land classes during either of the two periods. Results suggest that the first period from 1975 to 1992 was characterised by land‐intensive agricultural expansion and the conversion of forest into grass and agricultural land. During the second period, since 1992, the rapid, more labour‐ and capital‐intensive growth in the agricultural sector was enabled by the introduction of fertiliser, improved access to rural roads and markets, and expansion of the irrigated area. These policies, combined with the introduction of protected forest areas and policies discouraging shifting cultivation during the second period reduced the pressure on forests while at the same time increasing agricultural productivity and incomes for a growing population. Forest cover during the second period mainly increased due to the regeneration of areas formerly used for shifting cultivation.     

Nonfarm employment,agricultural intensification,and productivity change: empirical findings from Uganda

This article uses panel data from the Living Standards Measurement Study‐Integrated Surveys on Agriculture for Uganda to assess the farm‐level effects of nonfarm employment on agricultural intensification and productivity change. A sample selection model is used to account for both unobserved heterogeneity and potential simultaneity between agricultural production and nonfarm income. Results show that nonfarm employment can have differential impacts on farm technology intensity and productivity. Nonfarm income is found to have a positive impact on farm hired labor and improved seed intensity; a negative effect on on‐farm family labor use; and no significant impact on fertilizer, soil water management, and joint use of farm technologies. The econometric evidence also indicates that agricultural productivity declines as nonfarm income increases. Taken together, our findings reveal important trade‐offs between nonfarm employment and income and farm productivity growth under smallholder agriculture. The results indicated that targeted policies are required to reduce these potential trade‐offs between nonfarm employment and agricultural intensification and productivity change.     

Decomposing Changes in Agricultural Producer Prices

This article develops a method for decomposing changes in agricultural producer prices. The method builds on a procedure used by the World Bank, with the main variables in the decomposition being trade prices, exchange rates and trade policies. We expand on the World Bank decomposition procedure by broadening the analysis of policy effects, adding the effect from incomplete transmission of changes in trade prices and exchange rates to producer prices, and handling the effect on prices from interactions between variables as they change simultaneously. Decomposition results are presented for various commodities for the major emerging markets of Brazil, China and South Africa.     

Returns to spending on agricultural extension: the case of the National Agricultural Advisory Services (NAADS) program of Uganda†

The aim of this paper is to assess the direct and indirect impacts of the agricultural extension system of Uganda, the National Agricultural Advisory Services (NAADS) program, on household agricultural income. Data from two rounds of surveys of Ugandan rural farm‐households conducted in 2004 and 2007, as well as different program evaluation methods and model specifications, are used to estimate impacts and compute a rate of return. The direct and indirect impact of the program is estimated at 37–95% and 27–55% increase in per capita agricultural gross revenue between 2004 and 2007 for households participating directly and indirectly in the program, respectively, compared to nonparticipants. The rate of return on the program's expenditures is estimated at 8–49%. The program has been relatively more effective among male‐headed, larger, and asset‐poor households, as well as those taking up noncrop high‐value enterprises and living further away from financial services, all‐weather roads, and markets or located in the Eastern and Northern Regions. Policy implications of the results are drawn.     

Effects of international shocks and domestic macroeconomic policies upon Brazilian agriculture

An identified vector-autoregressive model is used to analyze the transmission of external commodity shocks to the Brazilian economy. The effects of the interaction between domestic macroeconomic (monetary and exchange rate) policies and external shocks to agricultural commodity (raw material and food) prices and crude oil price upon domestic (agriculture/industry) terms of trade are estimated.     

What agricultural and food policies do U.S. consumers prefer? A best–worst scaling approach

Consumer welfare effects from policy changes are traditionally calculated using estimates of consumer preferences for the underlying goods and services affected. This conventional approach is indirect, does not consider preferences people may have for the policies themselves, and makes it difficult to easily compare relative preferability of a large set of policy options. In this paper, we use the best–worst scaling approach to determine consumers’ preferences for 13 policies. A nationwide survey of 1,056 U.S. consumers indicates the highest levels of support for investments in agricultural research and requirements of food and agricultural literacy standards in public education. Fat, calorie, and soda taxes are the least popular; fewer than one-third of respondents are in favor of these three policies.     

农地流转区域差异及其成因分析 ——以江苏省为例

研究目的：分析农地流转发展的区域差异,以及这种差异的主要成因。研究方法：文献分析,计量经济分析。研究结果：（1）江苏省农地流转发展水平存在区域差异,苏南地区的农地流转比例最高,而苏北地区的农地流转增速最快,且已超过苏中地区的农地流转比例;（2）农地流转的区域差异是多种因素共同作用的结果,地区经济发展和农村劳动力非农就业都对农地流转具有显著的推动作用,鼓励和扶持农地流转的农村土地政策有效促进了农地流转的发展,农地产权安全性对农地流转的影响并不显著,而紧张的农村人地关系和与种植面积（承包面积）挂钩的农业补贴政策对农地流转具有一定的阻碍作用。研究结论：为了进一步促进农地流转和实现农业适度规模经营,应该因地制宜引导农村劳动力非农转移,完善农业补贴制度,并逐步探索农地流转专项补贴。
