FOOD INFLATION IN MALAWI: IMPLICATIONS FOR THE ECONOMY AgEcon
Ularo, Khonje Makaiko Gonapanyanja.
Despite consecutive years of good harvest, Malawi has experienced continuous price escalation of staple food commodities unsolved over the time. The real price of maize in Malawi has increased by 141 percent between 1998 and 2008, and has been rising along with the food prices of many other commodities over this period. This study therefore investigates the determinants of food inflation rate in Malawi and its effect on the economy. Monthly and annual data were collected from National Statistical Office and Reserve Bank of Malawi from 1978 to 2008. Data were analyzed by estimating an error correction model (ECM). The results show that fertilizer prices, crop diversification index, maize prices, diesel prices, real exchange rates and real interest rates...

Determinants of Selected Agricultural Export Crops in Nigeria: An Ecm Approach AgEcon
Yusuf, Sina A.; Yusuf, W.A..
This study examines the factors that determine the export performance of three major agricultural exportable commodities of cocoa, rubber and palm-kernel in the context of liberalization. Using time series data covering thirty three years and to avoid spurious result, error correction model was applied in the analysis. The unit root test is in line with the a priori expectation that macroeconomic variables are not stationary at their level. Virtually all the variables tested were differenced once before attaining stationarity. Each of the three equations indicated that the dependent variables cointegrated with their arguments at 1 percent level. There is the existence of short term and long term equilibrium relationships between the dependent variables and...

RAZÃO ÓTIMA DE HEDGE PARA OS CONTRATOS FUTUROS DO BOI GORDO: UMA ANÁLISE DO MECANISMO DE CORREÇÃO DE ERROS AgEcon
Zilli, Julcemar Bruno; Silva, Adriana Ferreira; Campos, Silva Kanadani; Costa, Jaqueline Severino.
A gestão dos resultados das atividades agropecuárias tem se tornado um constante desafio para os empresários rurais e a sua mensuração é imprescindível para o planejamento e análises de desempenho. No caso do mercado do boi gordo não tem sido diferente, principalmente, no que se refere às oscilações apresentadas nos preços. Nesse sentido, o mercado futuro tem se traduzido em um importante instrumento para reduzir os riscos de oscilação de preços. Porém, o pecuarista precisa identificar qual a proporção da produção que deve ser protegida. Assim, o objetivo principal do presente estudo consiste em estimar a razão ótima de hedge (ROH) para os pecuaristas da região de Cuiabá/MT e Campo Grande/MS utilizando o Mecanismo de Correção de Erros (MCE) para os dados...

Induced Innovation in Italy: An Error Correction Model for the Period 1968-2002 AgEcon
Baldi, Lucia; Casati, Dario.
In this work we utilise CES approach where factor ratios (mechanical power/labour and fertilizer/land) are regressed on price ratios and efficiency parameters (public and private R&D) to obtain a direct test of the induced innovation in Italian case for the period 1968-2002. Provided that inducement hypothesis implies a long run relationship an error correction model (ECM) is estimated to separate long-run effect, that is technological innovation, from short-run effects, that is factors substitution. The results corroborate the induced innovation hypothesis and underline the importance of private R&D in Italian agriculture.

Exportação brasileira de soja em grãos: evolução e considerações sobre seus determinantes para o período de 1980–2001 AgEcon
Figueiredo, Adelson Martins; Silva, Tania Araujo.
This work presents the results of the estimation of a soybean exportation function for Brazil, in the period between 1980 and 2001. The dynamics of the exportations were specifically analysed with focus on the 90s, due to the higher degree of economic opening of that decade, and the impacts of the fluctuating exchange rate over the determinants of the exports of this sector. The model proposed to estimate the exportation fuction of the soybeans was the Error Correction Model, which fit well to the variables that were specified and returned the expected relationships among the estimated parameters. The elasticities obtained were high and significant, which indicated that the exports react to variations in external price, internal price and internal revenue....
