2011 Updated Arkansas Global Rice Model

Bitsch, Vera.

The Michigan State University (MSU) Dairy Team conducted an industry survey with the objectives of identifying and rating industry priorities. After holding discussion groups across the state, two questionnaires were developed and sent to 2,237 dairy farm owners and operators and 480 allied industry professionals in the state; 23.4% of the dairy farmers and 28.1% of the allied industry professionals returned questionnaires with useable data. This report summarizes respondents’ ratings of industry issues, as well as education and knowledge needs. In addition, educational preferences, management practices, Internet use and access, demographic information, and farm characteristics are outlined.

The Arkansas Global Rice Model is based on a multi-country statistical simulation and econometric framework. The model is disaggregated by five world regions: Africa, the Americas, Asia, Europe, and Oceania. Each region includes country models which have a supply sector, a demand sector, a trade, stocks and price linkage equations. All equations used in this model are estimated using econometric procedures or identities. Estimates are based upon a set of explanatory variables including exogenous macroeconomic factors such as income, population, inflation rate, technology development, and especially, government determined policy variables which reflect the various mechanisms by which countries intervene in their rice sector economy. Individual country...

A Comparative Study of China's and Australia's Cotton Production

Zhao, Xufu; Tisdell, Clement A..

After providing information about the global importance of cotton as a textile and China’s and Australia’s contribution to global cotton production, this paper examines and compares trends in the time-series of cotton production of China and Australia for the period 1980-2007. In doing so, it takes account of changes in the area planted with cotton and its yield. Correlation estimates and decomposition analysis are used to determine the relative contribution to variations in the total output of cotton of changes in the total area planted with cotton and its yield in both countries. These relative contributions are found to be quite different for Australia and China. In addition, there is a comparative analysis of fluctuations in the production of cotton,...

Herbicide-resistant (HR) rice technology is a potential tool for control of red rice in commercial rice production. Using an ex ante mathematical programming framework, this research presents an empirical analysis of HR rice technology adoption under uncertainty. The analysis accounts for stochastic germination of red rice and sheath blight to model a profit maximization problem of crop rotation among HR rice, regular rice, and soybeans. The results demonstrate that risk attitudes and technology efficiency determine adoption rates and optimal rotation patterns.

Agricultural insurance is considered to be an effective to manage rural risks. Surprisingly, its adoption by farmers is very limited all over the world. An outstanding exception is the United States of America, country in which this instrument has achieved remarkable success. Nevertheless, the process of diffusion of agricultural insurance in the USA was slow and expensive. It has also required significant government intervention through a variety of complementary actions. In this context, countries willing to introduce this instrument among other agricultural policy tools, as it seems the case of Brazil, should proceed with caution. Agricultural insurance success has important pre-requisites and its general diffusion may amplify its problems. The analysis...

A FARM LEVEL ANALYSIS OF THE RELATION BETWEEN CAP REFORMS AND LOCAL ENVIRONMENTAL LEGISLATIONS: HOW AND IN WHICH EXTENT FLEMISH DAIRY FARMERS CAN FILL UP EXTRA MILK QUOTA?

Van der Straeten, Bart; Buysse, Jeroen; Nolte, Stephan; Marchand, Fleur L.; Lauwers, Ludwig H.; Claeys, Dakerlia; Van Huylenbroeck, Guido.

The agricultural policies shift gradually from EU-level organised market interventions to local organised environmental policies. This paper explores the growth possibilities of the Flemish dairy sector with the outlook of a quota abolishment as a case study of this policy shift. The dairy quota policy seems very restrictive for the highly profitable Flemish dairy sector, but the environmental restrictions from the manure regulation can limit the growth of the dairy sector as well. The paper uses a spatial multi-agent simulation model applied to a sample of 40.000 farms to estimate price development of emission rights and their possible impact on the growth of the dairy production. The results show that a higher milk production leads to higher prices for...

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...

Elbehri, Aziz; McDougall, Robert; Horridge, Mark.

This paper describes a global model for agriculture and bioenergy (GLOMAB) that incorporates biomass, biofuels and bioelectricity sectors into the GTAP-Energy model by expanding the global GTAP database, production and consumption structures. Biofuels are separated between first- generation (sugar ethanol, starch ethanol) and second- generation (cellulosic ethanol) biofuels and associated biomass feedstocks (maize, sugar cane, crop residues, woody biomass). Beside biofuels, the model also incorporates bioelectricity (as separate form conventional electricity) which competes for the same biomass feedstocks with cellulosic ethanol sector (agricultural residues, woody biomass). With this broad-based representation of the bioenergy system likely to prevail...

This article introduces the Hedonic Metric (HM) approach as an original method to model the demand for differentiated products. Using this approach, initially we create an n-dimensional hedonic space based on the characteristic information available to consumers. Next, we allocate products into this space and estimate the elasticities using distances. What distinguishes our model from traditional demand models such as Almost Ideal Demand System (AIDS) and Rotterdam Model is the way we link elasticities with product characteristics. Moreover, our model significantly reduces the number of parameters to be estimated, thereby making it possible to estimate large number of differentiated products in a single demand system. We applied our model to estimate the...

A Model of Producer Incentives for Livestock Disease Management

Ranjan, Ram; Lubowski, Ruben N..

We examine the management of livestock diseases from the producers' perspective, incorporating information and incentive asymmetries between producers and regulators. Using a dynamic model, we examine responses to different policy options including indemnity payments, subsidies to report at-risk animals, monitoring, and regulatory approaches to decreasing infection risks when perverse incentives and multiple policies interact. This conceptual analysis illustrates the importance of designing efficient combinations of regulatory and incentive-based policies.

Lovo, Stefania; Magnani, Riccardo; Perali, Carlo Federico.

This paper develops a multi-regional general equilibrium model (MEG-R) to compare the social desirability of the CAP reform in the three Italian macro-regions: North, Center and South. The model employs a mixed complementary framework that allows for the decision of not producing a particular crop in one or more regions and presents an attempt to model interregional trade flows. The model incorporates the links between production and consumption that characterize farm household’s behavior and allows for heterogeneous household responses across regions. Results show a general tendency to reallocations from cereal crops to forage that appear more severe in the South. In this region, the reduction in crops cannot be translated into an effective expansion of...

This study identifies the effects of the 1992 and subsequent CAP reforms on arable farmland price in Belgium. We first propose a brief literature review of studies identifying the determinants of farmland price. Afterwards, we use a panel data set to estimate a capitalization model of farmland price. We first show that the compensatory payments introduce by the 1992 CAP reform exert a positive effect on the arable farmland price in Belgium. We also identify a structural break in the land price equation after the adoption of the new support instruments as well as a regional break between Wallonia and Flanders.

This research analyses the impacts of a scientific advance that improves animal welfare, upon the environment and trade in Scotland using partial equilibrium (PE) modelling. The science improves pig neonatal survival through improved (high fibre) sow diets used before mating. Our model simulates the effects of animal welfare changes on the pig production systems (pig meat) and further on trade flows (trade in pig meat) and environment (water and air pollution). We consider two animal welfare simulation scenarios, namely the status quo – no animal welfare change as regards pig neonatal mortality (baseline scenario) and the case of improving pig neonatal survival (alternative scenario) and compare the impacts on trade and environment between the two...
