A Case Study of Regulation in Zambia’s Cotton Sector. AgEcon
Tschirley, David L.; Kabwe, Stephen.
Cotton is an unquestioned success of Zambia’s turn towards a market economy. After privatization in late 1994, seed cotton production rose from 32,000 metric tons (mt) to about 180,000 mt a decade later (three-year averages centered on 1994 and 2005). The number of farmers involved in the sector grew similarly, yields trended upwards (though slowly), and the country dramatically improved the quality of its lint, becoming the outstanding performer in Sub-Saharan Africa in this regard by the mid-2000s. Yet the sector has experienced two serious crashes since reform, both involving rampant credit default by farmers supported with seasonal input credit by ginning companies.

A Categorical Data Analysis on Risks in Agriculture AgEcon
Uematsu, Hiroki; Mishra, Ashok K..
This study compares farm operators’ risk perceptions and actual realization of risk attitudes revealed through off-farm labor, enterprise diversification, and use of contracts, crop insurance, and other types of insurance, using data from 2001 Agricultural Resource Management Survey (ARMS). Results from ordered logit model and multivariate probit models unexpectedly found that risk loving farmers are more likely to employ risk management strategies.

A Comparative Study of China's and Australia's Cotton Production AgEcon
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,...

A mosaic type of development - the Agri-food Districts experience in Italy AgEcon
Brasili, Cristina; Fanfani, Roberto.
The Italian Industrial Districts (IDs) are now considered in the national and international literature as one of the main factors of the successful and rapid industrial development of Italy after the Second World War. In this paper we outline the general characteristics of the IDs approach and then the distinctive figures of the agrifood districts. A mosaic type of development characterised the geographical distribution of the different agrifood districts in the Italian experience. The different origins of agrifood districts often determines their production and structural characteristics of firms, with a relevant role of SMEs. In many cases, these districts originated from handcraft traditions and specific local demand. Their specialized production is...

A Panel Data Analysis of the Determinants of Farmland Price: An Application to the Effects of the 1992 Cap Reform in Belgium AgEcon
Duvivier, Romain; Gaspart, Frederic; Frahan, Bruno Henry de.
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.

Actuarial Implication of Structural Changes in El Niño-Southern Oscillation Index Dynamics AgEcon
Chen, Shu-Ling.
The influence of climate variability on agricultural production and financial risks faced by an individual or an institution has been the center of the public discussion in the recent years. The changing weather patterns and environmental conditions could cause substantial unpredicted economic loss. Failure to capture the changing climate would underestimate the insurance contract’s expected indemnity and further create a major obstacle for insurance sectors. In this paper, we undertake a case study of El Niño-Southern Oscillation Index insurance for coastal Peru proposed by Skees. We examined the behavior of El Niño dynamics and found El Niño indices are changing over time. A class of generalized autoregressive conditional heteroskedasticity (GARCH)...

Agricultural Clusters in China AgEcon
Kiminami, Lily; Kiminami, Akira.
The purpose of this study is to assess the potential of clustering in the development of agriculture and rural communities in China. We shall examine in detail the food industry, which is the link in the food chain that propels the industrialization of agriculture, and identify instances of industrial agglomeration and business collaboration. Next, we shall analyze the externalities (i.e. spillovers) of clusters, demand conditions in cluster formation, and the effectiveness of business collaborations.

Agricultural Development in Traditional Asian Economies: Observations Prompted by a Livestock Study in Vietnam AgEcon
Tisdell, Clement A..
China began its economic reforms in 1979 and Vietnam followed in 1986. Since then both countries have experienced rapid economic growth, falling poverty rates and significant rises in per capita income. At the same time, substantial restructuring of their economies has occurred, a feature of which has been a decline in the relative contribution of agriculture to total employment and output. These changes are outlined. Significant changes have also occurred in the agricultural sectors of China and Vietnam and these are reviewed. In both countries, the livestock sector has grown in relative importance. Households are the main contributors to agricultural production but their individual holdings of land are small and households keeping livestock mostly only...

Agricultural Productivity Convergence: Myth or Reality? AgEcon
Poudel, Biswo N.; Paudel, Krishna P.; Zilberman, David.
We tested agricultural productivity convergence in the United States using the state level total factor productivity data and utilizing new estimation and cluster identification methods to identify convergence in the data. The empirical investigation did not indicate any evidence of agricultural total factor productivity (TFP) convergence at the state level. However, we found the evidence of TFP convergence at the regional level for some regions/clusters.

AGRI-ENVIRONMENTAL MEASURES ADOPTION: NEW EVIDENCE FROM LOMBARDY REGION AgEcon
Bertoni, Danilo; Cavicchioli, Daniele; Pretolani, Roberto; Olper, Alessandro.
As a consequence of the ‘greening’ process of the Common Agricultural Policy (CAP) the demand for evaluation of actual agri-environmental measures (AEMs) calls for a deeper analysis of this policy instrument implementation. The idea behind this paper is that farmers’ willingness to participate is a necessary but not a sufficient condition in explaining the AEMs local uptake. Specifically, we test whether AEMs adoption depends both on farms and farmers’ characteristics, and on the local political and institutional framework, as well. Discriminating between genuine farmer incentive and attitude towards AEMs from the role played by the local institutional environment, appears a crucial step toward a better understanding of agri-environmental schemes....

An Analysis of Global Timber Markets AgEcon
Sohngen, Brent; Mendelsohn, Robert; Sedjo, Roger A.; Lyon, Kenneth S..
This paper presents a model of global timber markets that captures the evolution of a broad array of forest resources and timber market margins over time. These margins include the inaccessible northern and tropical margins, plantation establishment, and timberland management. A baseline case is presented and discussed. Five alternative scenarios are then presented. These scenarios allow us to consider several important questions about timber market behavior and the future supply of industrial fiber: (1) What happens along the northern and the tropical inaccessible margins? (2) What role do timber plantations play? and (3) How do shifts in management intensity interact with market forces? The baseline case suggests that both prices and harvests rise over...

AN IMPACT ASSESSMENT OF THE FUTURE CAP REFORM ON THE ITALIAN TOMATO SECTOR AgEcon
Arfini, Filippo; Donati, Michele; Petriccione, Gaetana; Solazzo, Roberto.
The Health Check (HC) document traces the path for a new revision of the CAP. The communication content can be summarised in the following points: decoupling at regional and not at historical level, a more intensive modulation mechanism differentiated according to the total volume of subsidy received by the farm and a new implementation of the art. 69. The aim of this paper is to assess the effect of the HC on the farms producing fruits and vegetables in Italy, with a particular emphasis on the processed tomato production. The model based on the PMP approach simulates the regionalisation mechanism and the new modulation per brackets. The analysis carried out on a FADN sample of farms located in Emilia-Romagna region highlights as the HC new measures affect...

An Investigation of Significant Factors Influencing Western Australian Wool Producers to Produce Wool: A Structural Equation Modelling Approach AgEcon
Quaddus, Mohammed; Islam, Nazrul; Stanton, John.
Why Australian wool producers remained in the business despite the hardship they have experienced for much of the 1990s from low prices of wool? This question was raised frequently by research scientists and policymakers of the wool industry. A recent exploratory study gives a notion that Australian wool production could be a 'lifestyle' choice and/or a choice other than economic reasons. To validate this notion this paper investigates the factors that drive and motivate the Western Australian wool producers, as identified in the exploratory study, by applying a Structural Equation Modelling approach. An innovative mixed research method is adopted in this study. Telephone survey is conducted among a random selection of 290 wool producers in WA. The results...

Análise da participação da agropecuária no PIB dos EUA de 1960 a 2001 AgEcon
Brugnaro, Ricardo; Bacha, Carlos Jose Caetano.
This paper analyses the evolution of agriculture’s participation in the US gross domestic product (GDP) from 1960 to 2001. An econometric model is run in order to identify the main variables that determine this participation. From 1960 to 2001, there is a downward trend of agriculture’s participation in the US GDP with a break from 1971 to 1973, in other words, agriculture’s participation in the US GDP decreased from 1960 to 1970, increased from 1971 to 1973 and decreased again from 1973 to 2001. The 1971-1973´s break in the downward trend of agriculture’s participation is econometrically proved. Dataset organized in graphs show grain and meat production steadily enlarged from 1970 to 2001, what is closely related to the productivity increase and federal...

Análisis económico de la “bio-carbonización” como práctica de manejo agrícola AgEcon
Ramirez, Juan Andres; Rosales Alvarez, Ramon.
Las altas concentraciones de gases de efecto invernadero, específicamente CO2, han sido señaladas como la principal causa del cambio climático. La adopción de prácticas agrícolas capaces de incrementar el contenido de carbono en el suelo, ha sido propuesta como una estrategia de bajo costo y disponibilidad inmediata para enfrentar este fenómeno. La Bio-carbonización es una de estas prácticas agrícolas, la cual implica la aplicación de carbón vegetal al suelo, de modo que el carbono queda capturado en una forma altamente recalcitrante al tiempo que se mejora la calidad del suelo. Este artículo es el primero en evaluar la viabilidad financiera y considerar algunos de los efectos económicos de la práctica, estimados para una finca tipo en la altillanura...

Analisis Malmquist y DEA intertermporal de las agriculturas de la Union Europea AgEcon
Aldaz, Natalia; Millan, Joaquin A..
En este trabajo se realiza un análisis comparado de dos métodos no paramétricos de medida de productividad total de los factores con datos de panel basados en programación: índices de Malmquist y un modelo DEA intertemporal que permite acotar las medidas de eficiencia y progreso técnico, suponiendo cambio técnico no regresivo. La aplicación se realiza sobre las agriculturas de los países de la Unión Europea, encontrándose algunas diferencias importantes entre ambos enfoques. Los resultados sugieren menor crecimiento de productividad agraria y, sobre todo, una ordenación distinta de países en relación con dichos crecimientos que los encontrados en otros trabajos.
