Agricultural Policy and Its Impact on Labor Migration from Agriculture AgEcon
D'Antoni, Jeremy M.; Mishra, Ashok K..
Recent generations of farmers have experienced considerable difficulties earning a consistent living wage to support the needs of themselves and their families. To meet these needs, many farmers and their spouses have increasingly left the agricultural industry to seek employment. Previous studies have found government policies intended to slow the migration of labor from agriculture have little influence. Using an autoregressive distributed lag model and adjusting for non-stationary variables in the labor migration equation, direct government payments were found to have a negative and significant effect on labor migration from agriculture.

Comparison of a time series analysis of bulk tank somatic cell counts of dairy herds located in Brazil and the United States. Repositório Alice
RODRIGUES, L. G.; AQUINO, M. H. C. de; SILVA, M. R.; MENDONCA, L. C.; MENDONÇA, J. F. M. de; SOUZA, G. N. de.
Abstract: Bulk tank somatic cell counts (BTSCC) is widely used to monitoring the mammary gland health at the herd and regional level. A time series of BTSCC from specific regions or countries can be used to compare the mammary gland health according to regions and estimate the trend of subclinical mastitis of dairy herds at the regional level. This data support economic decisions related to mastitis control at the regional herd level. Still, decisions at the regional or country level are mainly used to investigate the efficiency of the mastitis control program. Three time series of BTSCC from dairy herds located in the USA and the southeastern region of Brazil were evaluated from 1995 to 2014. The first and second USA time series presented an increasing...

Corn Price Behavior – Volatility transmission during the boom on futures Markets AgEcon
Ledebur, Oliver von; Schmitz, Jochen.
Since 2000 a number of factors impacted agricultural markets drastically. Among these are structural changes in global demand and repeated supply constraints that supported the observed positive development of agricultural prices. Given the increasingly interdependent global markets, the question arises of in how far an isolated view of a single market, when analysing price volatility, is sufficient? The paper is a contribution to the debate on the recent commodity price bubble and the relationship among commodity futures markets for agricultural raw materials. More particularly, the transmission of price volatility between commodity future markets is analysed. The background question is whether and to what extent the volatility of agricultural commodity...

Partial equilibrium model of Czech beef trade AgEcon
Maly, Michal; Mala, Zdenka; Sobrova, L.; Halova, P..
The paper is focused on the modeling of a partial equilibrium on the beef market in the Czech Republic. The goal of the paper is a construction and a quantification of a partial equilibrium model of mentioned trade, used for simulation purpose and enabling delimitation of main determinants of beef supply and demand. Data was gained from standard statistical reports of the Ministry of Agriculture and from Statistics of Households Accounts from the year 1995 – 2009. Proposed model respects three levels of beef chain – farmer, processer and consumer. Simultaneously, it respects trade flows on an open market. From the functional point of view, it respects nonlinearity of suppose relationships. The model was quantified by OLS with respects of recursive...

PROJEÇÃO DO PREÇO RECEBIDO PELO PRODUTOR DE MELÃO NO ESTADO DO RIO GRANDE DO NORTE: UMA ABORDAGEM ARIMA AgEcon
Costa, Genivalda Cordeiro Da; Maia, Ana Cristina Nogueira; Rodrigues, Fabio Lucio.
No Estado do Rio Grande do Norte, o agronegócio é uma atividade que está crescendo cada vez mais devido ao setor fruticultura irrigada, destacando-se a produção de melão, que é um dos principais produtos agrícolas da economia norte-riograndense. Neste sentido, o objetivo do presente trabalho é simular previsões dos preços médios mensais recebidos pelo produtor de melão no Estado do Rio Grande do Norte no período compreendido entre março e agosto de 2008. Para tanto, utiliza-se o método Box-Jenkins, geralmente empregado para análise de séries temporais univariadas. Para identificar o processo autoregressivo integrado com médias móveis (ARIMA) que melhor se ajusta à série temporal para fins de previsão são apresentados quatro modelos candidatos para a...

Structural Change via Threshold Effects: Estimating U.S. Meat Demand Using Smooth Transition Functions AgEcon
Rodriguez, Nestor; Eales, James S..
Structural change remains a contentious issue in the literature. This study focuses on analyzing structural change in consumer demand for meats, which are modeled over the past half century. A standard inverse demand model is combined with a variant of the Smooth Transition Autoregressive (STAR) model. Results indicate that structural change has occurred and that con- sumers' preferences for meat are sensitive to in ation.
