2011 Updated Arkansas Global Rice Model AgEcon
Wailes, Eric J.; Chavez, Eddie C..
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 gender performance indicator for irrigation: Concepts, tools and applications AgEcon
van Koppen, Barbara.
Although gender issues are today a priority on the agendas of irrigation policy makers, interventionists, farm leaders and researchers, there is still a considerable gap between positive intentions and concrete action. An important but hitherto ignored reason for this is the lack of adequate generic concepts and tools that are policy-relevant and can accommodate the vast variation in irrigation contexts worldwide. The Gender Performance Indicator for Irrigation (GPII) aims to fill this gap. In any particular scheme, this tool diagnoses the gendered organization of farming and gender-based inclusion or exclusion in irrigation institutions. It informs irrigation agencies what they themselves can do for effective change-if necessary. The tool also identifies...

A Growth-Focused Spatial Econometric Model of Agricultural Land Development in the Northeast AgEcon
Hailu, Yohannes G.; Brown, Cheryl.
Using county data for West Virginia, Maryland, and Pennsylvania, estimation of a system of simultaneous equations shows that population growth, higher taxes, high farmland value, and high initial per capita income accelerate farmland development, but return on farmland, government assistance to farmers, farmland conservation, and farming agglomeration reduce development pressure.

A Mixed Effects Model of Crop Yields for Purposes of Premium Determination AgEcon
Roberts, Michael J.; Tack, Jesse B..
Farm income is highly variable due to annual price and yield uncertainties. The federally subsidized crop insurance program is an important tool for managing this risk, and has grown from a relatively modest program to one that encompasses the majority of productive cropland in the country. The success of this program depends on identification of actuarially fair insurance premium rates, which in turn depends on accurate estimation of farm-level yield distributions. We use the confidential U.S. Department of Agriculture Risk Management Agency (RMA) panel dataset to estimate farm-specific distributions of yields and actually fair crop insurance premiums. Our ongoing work includes using the difference between our estimated actually fair premiums and RMA's to...

A plot of one's own: gender relations and irrigated land allocation policies in Burkina Faso AgEcon
Zwarteveen, Margreet Z..
Discusses the potential opportunities and pitfalls of introducing market forces into the process of water allocation. Proposes several preconditions for beneficial privatization of water allocation and argues for a more sophisticated form of analysis than that generally allowed by proponents of basic needs or of free market approaches.

A Review of Milk Production in Bangladesh with Particular Emphasis on Small-Scale Producers AgEcon
Hemme, Torsten; Garcia, Otto; Khan, A.R..
The purpose of the study is to assess the economics of dairy farming in Bangladesh and the prospects for improving the dairy income for small-scale producers, which currently form the backbone of the dairy industry. The document begins with a general overview of milk production in the country, followed by a detailed study of dairy farming in the in the northern district of Sirajganj. The study applies a method of farm-level economic analysis developed by the International Farm Comparison Network (IFCN) which is based on the concept of ‘'typical farms’'. Three farm types were identified as ‘'typical'’ in the district and were subjected to detailed analysis: A two cow farm with 0.4 ha of land, a ten cow farm with 1.6 ha of land and a 25 cow farm with 1.8 ha...

A SYSTEM DYNAMICS MODEL OF AGRICULTURE AND RURAL DEVELOPMENT: THE TOPMARD CORE MODEL AgEcon
Johnson, Thomas G.; Bryden, John Marshall; Refsgaard, Karen; Alva Lizarraga, Sara.
The goal of the TOPMARD project is to develop a model of agriculture and rural development to better understand the agronomic, ecological, economic and social dimensions of rural regions. The resulting model, (Policy Model of Multifunctional Agriculture and Rural Development) was built collaboratively and hierarchically by the research teams from the 11 countries. The model features eight subsectors (Land, Agriculture, Tourism, Region, Human Resources, Non-commodities, Capital, and Quality of Life). Imbedded in the model are a complete dynamic input-output model, and an agecohort education demographic model. The model has both supply-side and demand-side drivers. Land use is the key supply-side driver. Land use, coupled with production system choices,...

A Tale of Two Market Failures: Technology and Environmental Policy AgEcon
Jaffe, Adam B.; Newell, Richard G.; Stavins, Robert N..
Market failures associated with environmental pollution interact with market failures associated with the innovation and diffusion of new technologies. These combined market failures provide a strong rationale for a portfolio of public policies that foster emissions reduction as well as the development and adoption of environmentally beneficial technology. Both theory and empirical evidence suggest that the rate and direction of technological advance is influenced by market and regulatory incentives, and can be cost-effectively harnessed through the use of economicincentive based policy. In the presence of weak or nonexistent environmental policies, investments in the development and diffusion of new environmentally beneficial technologies are very likely...

A TRADE LIBERALIZATION IN INTERNATIONAL DAIRY MARKETS AgEcon
Langley, Suchada V.; Blayney, Donald P.; Stout, Jim; Somwaru, Agapi; Normile, Mary Anne; Miller, James J.; Stillman, Richard.
International dairy industries remain among the most distorted agricultural sectors. Dairy average bound tariffs remain among the highest of all agricultural commodities, and dairy trade is characterized by a large number of megatariffs and tariff-rate quotas (TRQs). The objective of our study is to examine how the international dairy markets might respond to policy changes under various assumptions, using a partial equilibrium, multiple-commodity, multiple-region model of agricultural policy and trade. Our results indicate that liberalization will reduce supplies, increase dairy trade, and raise world prices.

Access to Land and Poverty Reduction in Rural Zambia: Connecting the Policy Issues AgEcon
Jayne, Thomas S.; Zulu, Ballard; Kajoba, Gear; Weber, Michael T..
Key Policy Message: - Despite having relatively low population densities, inadequate access to land is one of the major causes of rural poverty in Zambia. - The apparent paradox of inadequate access to land for many rural households in a country of low population density is partially reconciled when taking into account that economically viable arable land requires at least some degree of access to basic services, water, road infrastructure, and markets. The basic public investments to make settlement economically viable have yet been made in many areas of Zambia. - Depending of future land allocation policy, access to good quality land with a market potential may become increasingly beyond the reach of many small-scale farm households, making it more...

Aggregate Milk Supply Response to the Milk Income Loss Contract Program AgEcon
Bryant, Henry L.; Outlaw, Joe L.; Anderson, David P..
This research tests for changes in aggregate milk production due to the operation of the Milk Income Loss Contract (MILC) program since 2002. Aggregate production is decomposed into the size of the dairy herd and milk production per cow. We find no statistically significant response in either variable. This finding implies that the simultaneous operation of income and price support programs in the United States has not, thus far, proven self-defeating.

Agricultural Productivity and Policies in Sub-Saharan Africa AgEcon
Yu, Bingxin; Nin Pratt, Alejandro.
We analyze the evolution of Sub-Saharan Africa’s agricultural total factor productivity (TFP) over the past 45 years, looking for evidence of recent changes in growth patterns using an improved nonparametric Malmquist index. Our TFP estimates show a remarkable recovery in the performance of Sub-Saharan Africa’s agriculture between 1984 and 2006 after a long period of poor performance and decline. That recovery is the consequence of improved efficiency in production resulting from changes in the output structure and an adjustment in the use of inputs. Policy interventions, including fiscal, trade and sector specific policies, appear to have played an important role in improving agriculture’s performance. Despite the improved agricultural performance, SSA...

Agricultural science and technology policy for growth and poverty reduction AgEcon
Omamo, Steven Were; Naseem, Anwar.
This paper argues that the largely unrealized potential of agricultural science and technology (S&T) in promoting growth and poverty reduction in developing countries results from deeply rooted incompatibility among policy environments, institutional arrangements, and micro conditions and behavior in agricultural research and development (R&D). Achieving growth and poverty reduction based on greater agricultural productivity therefore means achieving greater compatibility among these three dimensions of agricultural innovation systems. Research is sorely needed to build understanding of (1) the “big picture” influencing agricultural S&T policy design and implementation in developing countries, (2) strategies for sustainable funding and delivery...

ALBERTA AGRICULTURE AND FOOD TRADE: RECENT TRENDS AgEcon
Rosario, Joe A..
Exports have been an integral and essential feature of the agriculture and food industry in Alberta. This is a product of the province’s relatively low population and consumption base on the demand side juxtaposed with a large resource base of prime agriculture land for crop production and an abundance of range and pasture for grazing and forage for raising livestock on the supply side. A host of factors influence the disposition of surplus production or exports including global supply/demand balances, relative cost/price relations, structural changes through farm consolidation and scale economies, market access, exchange rates, sanitary and phyto‐sanitary standards and regulations, disease and pest related issues. The inherent nature of agriculture means...

Alternative Instruments for Ensuring Food Security and Price Stability in Zambia AgEcon
Dorosh, Paul A.; Dradri, Simon; Haggblade, Steven.
Given heavy dependence on rainfed maize production, Zambia must routinely cope with pronounced production and consumption volatility in their primary food staple. Typical policy responses include increased food aid flows, government commercial imports and stock releases, and tight controls on private sector trade. This paper examines recent experience in Zambia, using a simple economic model to assess the likely impact of maize production shocks on the domestic maize price and on staple food consumption under alternative policy regimes. In addition to an array of public policy instruments, the analysis evaluates the quantitative impact of two key private sector responses in moderating food consumption volatility— private cross-border maize trade and...
