A TIME-SERIES ANALYSIS OF THE U.S.  DURUM WHEAT AND PASTA MARKETS
Provedor de dados: 31
Autores: Babula,   Ronald A.; Rich,   Karl M.
A quarterly, partial-equilibrium vector-autoregression model of the U.S. durum wheat and pasta markets was estimated and simulated under three trade-barrier changes that are of potential relevance for the current round of WTO agricultural negotiations: a rise in the U.S. market-clearing durum wheat quantity from increased imports; a policy- or tariff- reduction-induced decline in U.S. durum wheat price; and a tariff-induced rise in U.S. pasta product prices.  In response to each shock, an array of quarterly dynamic response characteristics are examined: response reaction times, direction and pattern of quarterly responses, response durations, response multipliers, and strength of durum/pasta market interrelationships.

Factor Demand, Output Supply Elasticities and Supply Projections for Major Crops of India
Provedor de dados: 31
Autores: Kumar,   Praduman; Shinoj,   P.; Raju,   S.S.; Kumar,   Anjani; Rich,   Karl M.; Msangi,   Siwa.
Policy planners face the challenge of formulating suitable agricultural policy by which the required growth in domestic production can be achieved. To attain effective food security policy, one needs reliable empirical knowledge about the degree of responsiveness of factor demand and output supply for commodities. This paper is an attempt in this direction and estimates the factor demand and output supply elasticity for major crops grown in India. These elasticities are used to project the domestic supply of major commodities, viz. rice, wheat, pulse grains, nine major edible oilseeds, and sugarcane under various scenarios with and without acreage expansion and TFP growth. The results of supply projections are compared with the food demand and policy...

The Role of Public-Private Partnerships and Collective Action in Ensuring Smallholder Participation in High Value Fruit and Vegetable Supply Chains
Provedor de dados: 31
Autores: Narrod,   Clare A.; Roy,   Devesh; Okello,   Julius Juma; Avendano,   Belem; Rich,   Karl M.
Many developing countries have moved into the production of non-traditional agricultural products to diversify their exports and increase foreign currency earnings. Accessing developed country markets and urban domestic markets requires meeting the food safety requirements due to several demand and supply side factors. Food retailers have developed protocols relating to pesticide residues, field and packinghouse operations, and traceability. In this changing scenario where food safety requirements are getting increasingly stringent, there are worries regarding the livelihood of the poor since companies that establish production centers in LDCs might exclude them. Poor producers face problems of how to produce safe food, be recognized as producing safe...

A SPATIAL MODEL OF ANIMAL DISEASE CONTROL IN LIVESTOCK: EMPIRICAL ANALYSIS OF FOOT AND MOUTH DISEASE IN THE SOUTHERN CONE
Provedor de dados: 31
Autores: Rich,   Karl M.; Winter-Nelson,   Alex.
This paper presents a multi-market model of animal disease control that extends the current literature by accounting for spatial and inter-temporal relations in both epidemiological and economic variables. The model is applied to Foot and Mouth Disease control in Argentina, Uruguay and Paraguay, but it is broadly generalizable.

Concepts, applications, and extensions of value chain analysis to livestock systems in developing countries
Provedor de dados: 31
Autores: Rich,   Karl M.; Baker,   Derek; Negassa,   Asfaw; Ross,   R. Brent.
The analysis of value chains has augmented our knowledge on the complexities, inter-linkages, distributional benefits, and institutional arrangements of production and marketing channels in developing countries.  However, the analysis remains relatively qualitative and case-specific, with limited ability to rank or assess the impact of alternative interventions or to analyze sufficiently the complex market dynamics and feedbacks present in livestock systems.  This paper offers insights on ways to improve the analytical rigor of the value chain methodology that combines both qualitative and quantitative approaches.

New Methods for Integrated Models of Animal Disease Control
Provedor de dados: 31
Autores: Rich,   Karl M.
Accurate assessments of the epidemiological and economic impacts of an animal disease require the incorporation of feedbacks between disease spread and production incentives. This paper motivates a new modeling framework that is sensitive to the dynamics of disease, production decisions and incentives, different livestock production systems, and their interaction through the use of an integrated system dynamics framework.  Preliminary simulation results are provided to demonstrate proof-of-concept of such an approach, with additional discussion given on extensions and implications of integrated methods.

THE CASSAVA STARCH INDUSTRY IN VIETNAM: CAN SMALL FIRMS SURVIVE AND PROSPER?
Provedor de dados: 31
Autores: Goletti,   Francesco; Rich,   Karl M.; Wheatley,   Chris.
The paper focuses on the starch industry in Vietnam.  That industry is mainly composed of small firms that adapted to rapid change over the past decade.  There are also large firms and multinationals in the industry.  Based on 1998 field survey data, an analysis of microefficiency and transaction costs suggests that small and medium firms can survive and prosper in the industry.  A policy strategy that promotes small and medium firms increases rural incomes, important in a country that is still mainly rural and where the income gap between urban and rural areas is growing.

Commodity-based Trade and Market Access for Developing Country Livestock Products: The Case of Beef Exports from Ethiopia
Provedor de dados: 31
Autores: Rich,   Karl M.; Perry,   Brian D.; Kaitibie,   Simeon.
While Ethiopia is Africa’s largest livestock producer, sanitary and phytosanitary (SPS) barriers and animal diseases have traditionally constrained market access. A system dynamics model examined the feasibility of a proposed SPS certification system under a number of scenarios. Model results indicate that the system may not be viable for beef exports to Middle Eastern markets. However, the binding constraint is high domestic input costs rather than the costs of SPS compliance. Sensitivity analyses reveal that while investments in feed efficiency and animal productivity would enhance Ethiopia’s export competitiveness, the competitive nature of international beef markets may still prevent market access.
