IMPLEMENTATION OF SINGLE AREA PAYMENT SCHEME IN THE EU NEW MEMBER STATES AgEcon
Davidova, Sophia.
The 2003 reform represents a significant shift in the EU policy, particularly in its movement to decoupled support. The potential impact of the reform depends on a range of factors including the modalities of its implementation and the structure of farming sectors in different countries. The then acceding countries had the flexibility to choose to implement the Single Payment Scheme (SPS) or to opt for the simplified Single Area Payment Scheme (SAPS). This paper attempts to provide a comparative overview of the level and distributional aspects of direct payments across seven New Member States (NMS) covering different sub-regions, the Baltics, Central and Eastern Europe, and the two most recent Member States from the Balkans – Bulgaria and Romania. Although...

A Framework for Estimating U.S. WTO Domestic Support to 2015 AgEcon
Quiroga, Jose.
The framework allows comprehensive and consistent measurement and classification of U.S. domestic support to 2015 under different assumptions. Projections of future U.S. domestic support patterns are made with estimates published in the USDA Agricultural Baseline Projections. We also use information from the OECD, FAPRI, NASS, and our own estimates. We present key elements and an overview of our analytical framework, assumptions of a baseline scenario, and some analytical results and observations arising from our analysis. The baseline scenario extends the classification of programs in WTO notifications to 2015. The framework consists of 65 spreadsheets, which are grouped into 4 analytical stages: calculation of program estimates by commodity; calculation...

STUDENT NUMBERS AND SUSTAINING COURSES AND FIELDS IN PH.D. PROGRAMS AgEcon
Davis, George C.; Perusquia, Ernesto.
Many agricultural economics departments are concerned about the vitality of their Ph.D. programs. A particular problem is insufficient student numbers to justify teaching certain courses or fields. As a consequence, much faculty time can be spent debating alternative program structures without any real idea of the likelihood that a proposed program structure will succeed. This article presents a framework for deriving some analytical and empirical results for alternative Ph.D. program structures. A downloadable program is used to generate some representative results that will hopefully help others minimize speculations and time spent in committee or departmental meetings.

Quality Certification by Geographical Indications, Trademarks and Firm Reputation AgEcon
Menapace, Luisa; Moschini, GianCarlo.
We study firm reputation as a mechanism to assure product quality in perfectly competitive markets in a context in which both certification and trademarks are available. Shapiro’s (1983) model of reputation is extended to reflect both collective and firm-specific reputations, and this framework is used to study certification and trademarks for food products with a regional identity, known as geographical indications (GIs). Our model yields two primary results. First, in markets with asymmetric information and moral hazard problems, credible certification schemes reduce the cost of establishing reputation and lead to welfare gains compared to a situation in which only private trademarks are available. Hence, certification improves the ability of reputation...

The 2005/06 South Dakota Grain Marketing Patterns Study: A Grain Elevator Survey Report AgEcon
Qasmi, Bashir A.; Hamda, Yonas; Fausti, Scott W..
This study reports the results of a survey of grain elevators in South Dakota completed in 2007 and focuses on the marketing patterns for spring wheat, winter wheat, oats, barley, corn, soybeans and sunflower seeds for the marketing year 2005/06. During the year, elevators’ market share in South Dakota was 54%, 83%, 91% and 83% for corn, soybeans, spring wheat, and winter wheat, respectively. Contrary to reports for Iowa and Indiana, the increase in ethanol production in the state did not have an adverse impact on elevators’ market share for corn in South Dakota. In terms of volume, cash purchase, delayed pricing, cash forward contracts, and hedge to arrive contracts, collectively, accounted for more than 95% of each of the grain and oilseed purchased by...

Philippine Rice and Rural Poverty: An Impact Analysis of Market Reform Using CGE AgEcon
Cororaton, Caesar B..
This paper looks at how Philippine trade reform which consists of tariff reduction and elimination of quantitative restrictions (QR) on rice imports will affect poverty within two world trade scenarios: Doha and free world trade. The impact of Doha is very small and generates biased effects against agriculture. The impact of Philippine trade reform within the Doha agenda magnifies this biased effect, making rural households worse-off compared to urban households. However, eliminating rice QR generates a set of effects where consumer price reduction dominates nominal income decline. Thus, real income improves and poverty declines across household groups, but the net effects are lower in rural than in urban households. The impact of a free world trade...

FUTURES AND OPTIONS MARKETS, BASIS, AND THE TIMING OF GRAIN SALES IN MONTANA AgEcon
Mastel, Mike; Buschena, David E..
The performance of the grain transportation industry, historically low real grain prices, and decreasing government support for grain prices have renewed interest in local grain prices and shipping costs. An understanding of the relationship between local cash prices and futures prices is an important part of minimizing the price risk associated with growing and merchandising grain. The ability to recognize the seasonal patterns between these prices offers improved profit potential for marketing grain. A Montana producer's decision of when and how to market his/her crop can have a great impact on net profit. Farm managers can use cash sales at or after harvest, forward contracting with a local grain elevator, or hedging with the use of futures and options...

CAP Reforms and Total Factor Productivity Growth in Belgian Agriculture: A Malmquist Index Approach AgEcon
Coelli, Tim J.; Perelman, Sergio; Van Lierde, Dirk.
Have the 1992 and 2000 CAP reforms had any discernable effect upon agricultural productivity? In this study we derive detailed information on the total factor productivity (TFP) growth of arable farms in Belgium over a 16-year period from 1987 to 2002. Calculations are based on a carefully constructed high-quality detailed farm-level data set containing 1728 observations, involving over 100 farms in most years. Three output variables (cereals, other crops, other outputs) and four input variables (land, labour, capital and other inputs) are constructed, using multilateral Fisher index numbers where crop aggregation is required. The TFP measures are calculated using a Malmquist TFP index relative to a series of data envelopment analysis (DEA) frontiers....

Natural Protection from International Competition in the Livestock Industry: Analysis, Examples and Vietnam's Pork Market as a Case AgEcon
Tisdell, Clement A.; Lapar, Ma. Lucila A.; Staal, Steven J.; Que, Nguyen Ngoc.
In some countries, local agricultural products (particularly livestock products) are shielded from international competition by ‘natural’ factors influencing the purchase of products. These factors include strong local tastes (or preferences) that favour the local product and the absence (or relative absence) of complementary retail outlets or home appliances suitable for storing and preparing potential imported substitutes. The desire for fresh meat rather than chilled or frozen meat, the absence or limited accessibility of supermarket outlets and limited refrigeration possibilities in homes can limit imports into developed countries of meat supplied by developed countries. From consumer’s perspectives these fresh or raw products are significantly...

GMOs: Prospects for Increased Crop Productivity in Developing Countries AgEcon
Evenson, Robert E..
Genetically Modified Crops (GMO foods) have been widely available to farmers since 1996. The Gene Revolution, based on recombinant DNA (rDNA) genetic engineering techniques, is seen by proponents as both supplanting Green Revolution varieties, based on conventional plant breeding techniques, and potentially enabling “disadvantaged” production environments, unreached by Green Revolution varieties to achieve productivity improvements. This paper argues that the private firms supplying GM crop products have generally had little interest in selling products in disadvantaged production environments. The paper also argues that present rDNA techniques allow only static gains from specific “trait” improvements. But these GM products can be installed on Green...

Determining Key Factors of Influence on the Profitability of Retaining Cull Cows Beyond Culling AgEcon
Amadou, Zakou; Raper, Kellie Curry; Ward, Clement E.; Biermacher, Jon T.; Cook, Billy.
Factors influencing the profitability of retaining and feeding cull cows beyond culling were investigated. First, a price response function is estimated using 19 years of monthly price data as reported by Agricultural Market Services (AMS). Net returns are then estimated using data from a three year cull cow feeding experiment conducted at The Samuel Roberts Noble Foundation and used to examine the relative effect of various factors on net returns. Results showed the importance of average daily gain increases across feeding periods while feeding system is also an important contributing factor to net returns.

Potential Implications of a Special Safeguard Mechanism in the WTO: the Case of Wheat AgEcon
Hertel, Thomas W.; Martin, William J.; Leister, Amanda M..
The Special Safeguard Mechanism (SSM) was a key issue in the July 2008 failure to reach agreement in the WTO negotiations under the Doha Development Agenda. It includes both price (P-SSM) and quantity-triggered measures (Q-SSM). This paper uses a stochastic simulation model of the world wheat market to investigate the effects of policy makers implementing policies based on the SSM rules. As expected, implementation of the Q-SSM is found to reduce imports, raise domestic prices, and boost mean domestic production in the SSM regions. However, rather than insulating countries that use it from price volatility, it would actually increase domestic price volatility in developing countries, largely by restricting imports when domestic output is low and prices...

Indian Farmers' Valuation of Crop Yield Distributions: Will poor farmers value 'pro-poor' seeds? AgEcon
Lybbert, Travis J..
Potential poverty traps among the rural poor suggest a need to reduce poor farmers' vulnerability by stabilizing crop yields and limiting yield losses. Advances in agricultural biotechnology enable breeders to address this need more directly than ever before with crops that reduce production risk by tolerating climate fluctuation or resisting biotic stresses. Will poor farmers who could benefit most from less vulnerability choose to purchase such risk-reducing seeds? I use data from a household survey and experiment involving farmers in India to infer their valuation of changes in the mean, variance, and skewness of yield distributions. I conclude that these farmers value increases in expected yield in the yield distribution but seem indifferent about...

Brand Information Mitigating Negative Shocks on Animal Welfare: Is It More Effective to “Distract” Consumers or Make Them Aware? AgEcon
Dentoni, Domenico; Tonsor, Glynn T.; Calantone, Roger J.; Peterson, H. Christopher.
To create and sustain a competitive advantage in markets that increasingly value animal welfare attributes, meat companies need to meet public and private production standards while communicating to final consumers through their brands. Data are collected from a representative sample of 460 U.S. residents through an on-line experiment on McDonald’s chicken breast sandwiches and analyzed with Latent Growth Modeling. This study assesses which content of positive brand information effectively mitigates the risk of negative information shocks on animal welfare. On average, brand information has the same positive impact on consumers’ beliefs and attitudes, regardless of whether it is related or unrelated to animal welfare. However, there is strong market...

The 2003 Mid Term Review of the Common Agricultural Policy: A Computable General Equilibrium Analysis for Ireland AgEcon
Dixon, Janine.
A Computable General Equilibrium (CGE) model of the Irish economy is built and used to analyse the 2003 Mid Term Review (MTR) of the Common Agricultural Policy. The MTR represents significant reform of agricultural policy in the EU, and has generated widespread interest and numerous studies of its anticipated effects. Economists have employed a variety of modelling approaches, encompassing single and multi-country general and partial equilibrium models. This research contributes a dedicated single country CGE modelling analysis of the MTR for Ireland. IMAGE2 is a CGE model with particular emphasis on the agriculture and food processing sectors, and the careful representation of CAP instruments. The database is the most detailed and current CGE database of...

Coordinating to Eradicate Animal Disease, and the Role of Insurance Markets AgEcon
Hennessy, David A..
Farmed animal production has traditionally been a dispersed sector. Biosecurity actions relevant to eradicating infectious diseases are generally non-contractible, and might involve inordinately high transactions costs if they were contractible. If an endemic disease is to be eradicated within a region, synchronized actions need to be taken to reduce incidence below a critical mass so that spread can be contained. Using a global game model of coordination under public and private information concerning the critical mass required, this paper characterizes the success probability in an eradication campaign. As is standard in global games, heterogeneity in private signals can support a unique equilibrium. Partly because of strategic interactions, concentrated...

CLIMATE CHANGE AND PRODUCTION RISK IN CHINESE AQUACULTURE AgEcon
Holst, Rainer; Yu, Xiaohua.
Drawing on the method developed by Just and Pope (1978, 1979), this paper separately analyzes the marginal contributions of both regular input factors and climate factors to mean output and to production risk in Chinese inland aquaculture. Furthermore, the net change in output following a 1°C increase in annual average temperature will be determined. According to the results obtained, the impending changes in global climate will have both positive and negative impacts. While an increment in annual average temperatures will increase mean output and decrease production risk, an increase in temperature variability will reduce mean output and cause a higher level of production risk. The corresponding measures of precipitation however have no significant impact...

Relational Contracting and Allocation of Decision Rights in the Agri-Food Industry: Producer Contracts and Food Safety AgEcon
Karantininis, Kostas; Graversen, Jesper T.; Rasmussen, Hans Jacob Nymann.
We apply a formal theoretical model of adaptation to two empirical settings within the agri-food industry: specialized pig production and food safety in Denmark. The objective is to allocate decision rights ex ante so that actual decisions taken ex post will optimize the profit accruing to the two parties in a contractual or integrative relation. Two applications are presented in this paper: First an actual partnership between two pork producers in Denmark. Based on detailed budgets we develop detailed schedules for the “reneging temptations” of the two partners- These are the temptations to renege on the contract during the evolution of the partnership. Using a model developed by Baker, Gibbons and Murphy (2006) we calculate equilibria using the Folk...
