Livestock in China: Commodity specific total factor productivity decomposition using new panel data
Provedor de dados: 31
Autores: Rae,   Allan N.; Ma,   Hengyun; Huang,   Jikun; Rozelle,   Scott.
Studies of total factor productivity in livestock production are rare, but when available provide useful information especially in the context of developing countries such as China where livestock is becoming more important in the domestic agricultural economy. We estimate total factor productivity (TFP) for four major livestock products in China employing the stochastic frontier approach, and decompose productivity growth into its technical efficiency and technical progress components. Efforts are made to adjust and augment the available livestock statistics. The results show that growth in TFP and its components varied between the 1980s and the 1990s as well as over production structures. While there is evidence of considerable technical innovation in...

The Impact of Situation and Outlook Information in Corn and Soybean Futures Markets: Evidence from WASDE Reports
Provedor de dados: 31
Autores: Isengildina-Massa,   Olga; Irwin,   Scott H.; Good,   Darrel L.; Gomez,   Jennifer K.
The purpose of this study was to examine the impact of situation and outlook information from World Agricultural Supply and Demand Estimates (WASDE) in corn and soybean futures markets over the period 1985 to 2006. Results indicate that WASDE reports containing National Agricultural Statistics Service (NASS) crop production estimates and other domestic and international situation and outlook information have the largest impact; causing return variance on report sessions to be 7.38 times greater than normal return variance in corn futures and 6.87 times greater than normal return variance in soybean futures. WASDE reports limited to international situation information and domestic and international outlook information have a smaller impact. The results show...

VARIATION IN MARGINAL RESPONSE TO NITROGEN FERTILIZER BETWEEN LOCATIONS
Provedor de dados: 31
Autores: Graybeal,   Dale K.
A logistic growth equation with time and location varying parameters was used to model corn response to applied nitrogen. A nonlinear dummy-variable regression model provided a parsimonious representation of site and time effects on parameter values. The model was used to test for the equality of the mean marginal product of nitrogen fertilizer between locations on the coastal plain of North Carolina. Monte Carlo simulation and bootstrap simulation were used to construct finite sample covariance estimates. Results support rejection of the hypothesis that mean marginal products are equal when nitrogen is applied at 168 kg/ac. A comparison of bootstrapped errors and asymptotic errors suggests that results based on asymptotic theory are fairly reliable in...

LIVESTOCK PRODUCTIVITY IN CHINA: DATA REVISION AND TOTAL FACTOR PRODUCTIVITY DECOMPOSITION
Provedor de dados: 31
Autores: Ma,   Hengyun; Rae,   Allan N.; Huang,   Jikun.
Studies of total factor productivity in livestock production are rare, but when available provide useful information especially in the context of developing countries such as China where livestock is becoming more important in the domestic agricultural economy. We estimate total factor productivity (TFP) for four major livestock products in China and by employing the random coefficient frontier approach, decompose productivity growth into its technical efficiency and technical progress components.  Efforts were made to adjust and augment the available livestock statistics. The results show that growth in TFP and its components varied between the 1980s and the 1990s as well as over production structures. While there is evidence of considerable technical...

Provedor de dados: 31
Autores: Nemessalyi,   Zsolt; Madai,   Hajnalka; Nabradi,   Andras.
The aim of this paper is to give an overview of the risk attitudes of Hungarian sheep producers regarding the changes they have had to go through since the political changes of 1989-1990. Moreover, the objective of this study is to strengthen the empirical basis for risk analysis by identifying the importance of farmers' risk attitudes. The results of a nationwide survey of over 500 sheep farmers presented a framework of risk attitudes, risk sources and applied risk management techniques of livestock producers..

Adjustment Capacity of Korean Farm Household
Provedor de dados: 31
Autores: Kim,   Hanho; Kim,   Jae-Kyung.
Structural adjustment is defined as the farm household’s behavior of changing its existing farm asset distribution toward more specialized or diversified directions. Farm households are classified into agricultural or non-agricultural based ones. Estimated expected income through switching regression model reveals that higher revenue is expected when adjustment paths toward more specialization and more non-agricultural based activities are chosen.

The Food Problem and the Evolution of International Income Levels
Provedor de dados: 31
Autores: Gollin,   Douglas; Parente,   Stephen L.; Rogerson,   Richard.
This paper examines the effect of agricultural development on a country’s overall development and growth experience. In most poor countries, large fractions of land, labor, and other productive resources are devoted to producing food for subsistence needs. This “food problem” can delay a country’s industrial development for a long period of time, causing its per capita income to fall far behind the world leader. Once industrialization begins, this trend is reversed. The extent to which a country catches up to the leader depends primarily on factors that affect productivity in non-agricultural activities: agricultural productivity is thus largely irrelevant in the very long run. But in the short run, a country that experiences large improvements in...

U.S. Cotton Prices and the World Cotton Market:  Forecasting and Structural Change
Provedor de dados: 31
Autores: Isengildina-Massa,   Olga; MacDonald,   Stephen.
The purpose of this study was to analyze structural changes that took place in the cotton industry in recent years and develop a statistical model that reflects the current drivers of U.S. cotton prices.  Legislative changes authorized the U.S. Department of Agriculture to resume publishing cotton price forecasts for the first time in 79 years.  In addition, systematic problems have become apparent in the forecasting models used by USDA and elsewhere, highlighting the need for an updated review of price relationships.  This study concluded that a structural break in the U.S. cotton industry occurred in 1999, and that world cotton supply has become an important determinant of U.S. cotton prices.  China’s trade and production policy also continues to be an...

Provedor de dados: 31
Autores: Black,   J. Roy; Nugent,   James; Rothwell,   Nikki; Thornsbury,   Suzanne; Olynk,   Nicole J.
The weighted average cost of producing tart cherries in Michigan on a representative farm in 2009 is $0.36/lb. This cost was averaged across the three main production regions in Michigan and weighted by average per acre production for each region as published by the Michigan Agricultural Statistics Service. --Costs vary across the main production regions and by farm size. Costs are about $0.04/lb less for mid-sized farms in Northwest Michigan and $0.08/lb and $0.10/lb in West Central and Southwest Michigan, respectively. --This report was developed through interviews with tart cherry growers and other experts in each of the three main growing regions in 2005 and 2006. Many of the numbers were updated in 2009. --The cost of production calculation is based...

Traceability -- A Literature Review
Provedor de dados: 31
Autores: Trautman,   Dawn; Goddard,   Ellen W.; Nilsson,   Tomas K.H.
In light of recent food safety crises and international trade concerns associated with food or animal associated diseases, traceability has once again become important in the minds of public policymakers, business decision makers, consumers and special interest groups. This study reviews studies on traceability, government regulation and consumer behaviour, provide case studies of current traceability systems and a rough breakdown of various costs and benefits of traceability. This report aims to identify gaps that may currently exist in the literature on traceability in the domestic beef supply chain, as well as provide possible directions for future research into said issue. Three main conclusions can be drawn from this study. First, there is a lack of a...

Economic Returns to Different Stocking Rates for Cattle on Ryegrass under Contract Grazing and Traditional Ownership
Provedor de dados: 31
Autores: Zaragoza-Ramire,   Jose-Luis; Bransby,   David; Duffy,   Patricia A.
Economic returns to stocker production were estimated using results of a grazing experiment.  If resources to buy cattle are not limited, traditional ownership was superior to contract grazing under all but extremely unfavorable price spreads.  If capital to purchase stockers is limited, contract grazing may provide more returns.
