Agricultural Productivity in the United States AgEcon
Ahearn, Mary Clare; Yee, Jet; Ball, V. Eldon; Nehring, Richard F..
Increased productivity is a key to a healthy and thriving economy. Consequently, the trend in productivity, economywide, is one of the most closely watched of our common economic performance indicators. Agriculture, in particular, has been a very successful sector of the U.S. economy in terms of productivity growth. The U.S. farm sector has provided an abundance of output while using inputs efficiently. Agricultural productivity growth has been an important source of U.S. economic growth throughout the century, but the years since 1940 have seen an even faster growth in agricultural productivity. The annual average increase in productivity from 1948 to 1994 was 1.94 percent. This reflects an annual growth in output of 1.88 percent per year and an actual...

KRAM - A Sector Model of Danish Agriculture - Background and Framework Development AgEcon
Wiborg, Torben.
A model of the Danish agricultural sector named KRAM (KVL's Regionalized Agricultural Model) is developed in this paper. KRAM can be described as a spatial, dynamic, nonlinear, programming sector model. KRAM's purpose is to make policy analysis in the complex market conditions Danish agriculture is working under today. In order to do this in the best possible way the model optimizes the production functions on a very disaggregated level. This allows for analysis of changes in physical constraints to production, as well as price changes. The model is capable of calculating some environmental effects of agricultural production, and provides detailed spatial description of the agricultural economy and production. The time horizon is 10 years, and the model...

Research on “Growth Drag” of Water Resource on Agricultural Development in China AgEcon
Wang, Xueyuan.
Based on the “growth drag” conceptual model of Romer, this paper computes the growth drag of water resource on agricultural development through using panel data(1997~2006) of China’s all provinces. The result shows the growth rate of agricultural production value fell 0.1121% per year on average because of the shortage of water resource. The number is seemingly small, but according to calculation, under the drag of water resource, the ratio will be reduced by 2.66% in 2030. Furthermore, it will be 3.74% in 2040 and 4.82% in 2050.

Beginning Farmers and Ranchers AgEcon
Ahearn, Mary Clare; Newton, Doris J..
USDA defines beginning farmers and ranchers as those who have operated a farm or ranch for 10 years or less either as a sole operator or with others who have operated a farm or ranch for 10 years or less. Beginning farmers tend to be younger than established farmers and to operate smaller farms or ranches, some of which may provide no annual production. Beginning farmers often face obstacles getting started, including high startup costs and limited availability of land. USDA—through the Farm Service Agency and the Natural Resources Conservation Service—provides loans and conservation assistance to beginning farmers and ranchers. This report draws on data from annual surveys and the Census of Agriculture to provide policymakers with a better understanding...

Meta-Regression Estimates for CGE Models: A Case Study for Input Substitution Elasticities in Production Agriculture AgEcon
Boys, Kathryn A.; Florax, Raymond J.G.M..
The selection of appropriate parameters for computable general equilibrium (CGE) models critically affects the results of applied economic modeling exercises. Valid and reliable parameter selection models are needed, and typically comprise direct estimation, expert opinion, or copycatting of results from seminal studies. The purpose of this study is to use meta-analysis to summarize and more accurately estimate elasticities of input substitution, specifically between labor and other inputs in agricultural production. We construct a comprehensive database of elasticity estimates through an extensive literature review, and perform a meta-regression analysis to identify structural sources of variation in elasticity estimates sampled from primary studies. The...

The Effects of Rural Infrastructure Development on Agricultural Production Technical Efficiency: Evidence from the Data of Second National Agricultural Census of China AgEcon
Li, Zongzhang; Liu, Xiaomin.
This paper studies the effects of rural infrastructure development on agricultural production technical efficiency, using data from the second agricultural census of China. Employing Data Envelopment Analysis, this paper first estimates agricultural production technical efficiency of each administrative area of China. A Tobit model is then applied to study the effects on agricultural production technical efficiency of various types of rural infrastructures. Our empirical results suggest that transportation infrastructure plays the most substantial positive role on technical efficiency, followed by vocational/technical education infrastructure, electricity facilities and water supply systems. In addition, other potential factors influencing agriculture...

Measuring the Impacts of Prime-age Adult Death on Rural Households in Kenya AgEcon
Yamano, Takashi; Jayne, Thomas S..
Using a two-year panel of 1,422 Kenyan households surveyed in 1997 and 2000, we measure how primeage adult mortality affects rural households’ size and composition, agricultural production, asset levels, and off-farm income. First, the paper uses adult mortality rates from available data on an HIV-negative sample from neighboring Tanzania to predict the number of deaths that might have been expected in the absence of HIV, and compares this to the number of deaths actually recorded over the survey interval in the Kenyan sample. Based on this procedure, only a quarter of the prime-age female deaths in the 25-34 age range and about half of the male deaths in the 35-44 year age range age range could have been predicted on the basis of the HIV-negative...

Impact of CAP reform on agricultural production in the German federal state Baden-Wurttemberg: Scenario calculations with the regional model ACRE AgEcon
Henseler, Martin; Krimly, Tatjana; Dabbert, Stephan.
ACRE is an Agro-eConomic model for agricultural pRoduction at rEgional level. Based on an extension of Positive Mathematical Programming (PMP) this model was developed as a decision tool for politics with respect to questions of global change- and political scenarios. ACRE was applied in two interdisciplinary projects for simulation of agricultural production in two German river basins. Currently, the model was extended to calculate agricultural production for the federal state Baden-Württemberg in South West Germany. This paper introduces the results of CAP scenario calculations with the regional model ACRE for Baden-Württemberg.

Agriculture’s contribution to rural viability: An approach to estimate regional economic impacts of agricultural policy in Swiss case study regions AgEcon
Kopainsky, Birgit; Flury, Christian; Giuliani, Gianluca.
This paper develops a thorough yet easily implementable approach to measuring agriculture’s contribution to rural viability. The approach is based on input-output modelling. It adopts a number of concepts from input-output modelling such as determining the explicit geographical origin of input requirements and the geographical destination of farm household expenditures without formerly developing an input-output table. The approach is applied to four case studies in the Swiss mountain regions and tested for three scenarios. Our results clarify the role that agriculture still plays in the context of rural viability. They demonstrate that agriculture’s contribution to rural viability differs considerably between the case study regions and that future...

A JAPÁN GAZDASÁG NÉHÁNY JELLEGZETESSÉGE A XXI. SZÁZAD FORDULÓJÁN AgEcon
Tompe, Ferenc.
Japán és a Távol-Kelet évtizedeken keresztül a világ egyéb térségeinek csodá-latát vívta ki elsősorban az átlagot meghaladó, gyors gazdasági növekedésével. Az 1990-es években a korábbi „keleti motor”-ként tekintett Japán gazdasága kü-lönleges helyzetbe került: a növekedés nagy mértékben lecsökkent, sőt hosszú időn keresztül alapvetően stagnált, az általánosan jellemző inflációt defláció váltotta fel. Ezek a jelenségek újból felkeltették a szakemberek érdeklődését a japán gazdaság iránt, egyfelől az előállt helyzet okainak feltárására, másfelől a megol-dások keresésére. A japán gazdaság megújulásának feltételeit döntően azok a té-nyezők határozzák meg, amelyek az elmúlt tíz évben a gyengélkedés okaiként je-lölhetők meg, mint pl. a hosszú ideig tartó...

Excess Capital in Agricultural Production AgEcon
Kumbhakar, Subal C.; Guan, Zhengfei; Oude Lansink, Alfons G.J.M..
In this article we propose a theoretical model for analyzing capital requirement in agricultural production and define excess capital thereupon. We develop a two-step method that allows endogenous regressors in the maximum likelihood estimation. The two-step procedure is also capably of recovering the parameters of time invariant variables in fixed effect models. The model and method are applied to a capital requirement study using data from cash crop farms in the Netherlands. Empirical results show that excess capital widely exists on the farm. The implications of excess capital are further demonstrated with a production frontier analysis.

Agricultural policies in India: Producer Support Estimates 1985-2002 AgEcon
Mullen, Kathleen; Orden, David; Gulati, Ashok.
Since the early 1990s, India has undergone substantial economic policy reform and economic growth. Though reforms in agricultural policy have lagged those in other sectors, they have nonetheless created a somewhat more open economic orientation. In this study, we evaluate the protection and support versus disprotection of agriculture in India. Our methodology involves examining market price support (MPS) for eleven crops, the expenditures on input subsidies benefiting farmers (for fertilizer, electricity and irrigation), and product-specific and total producer support estimates (PSEs) over the period 1985-2002. We draw on the extensive price-comparison and subsidy-measurement data sets and analysis developed earlier by Gulati and his co-authors, often...

Generating Plausible Crop Distribution and Performance Maps for Sub-Saharan Africa Using a Spatially Disaggregated Data Fusion and Optimization Approach AgEcon
You, Liangzhi; Wood, Stanley; Wood-Sichra, Ulrike.
Agricultural production statistics reported at country or sub-national geopolitical scales are used in a wide range of economic analyses, and spatially explicit (geo-referenced) production data are increasingly needed to support improved approaches to the planning and implementation of agricultural development. However, it is extremely challenging to compile and maintain collections of sub-national crop production data, particularly for poorer regions of the world. Large gaps exist in our knowledge of the current geographic distribution and spatial patterns of crop performance, and these gaps are unlikely to be filled in the near future. Regardless, the spatial scale of many sub-national statistical reporting units remains too coarse to capture the...
