It has been observed that most of the agricultural time series data in general and price particular are non-linear, non-stationary, non-normal heteroscedastic nature. Therefore, application usual linear nonlinear parametric models like Autoregressive integrated moving average (ARIMA), Generalized autoregressive conditional (GARCH) their component fail to capture variability present series. is a...

Agricultural growth is closely associated with sustainable economic development. This especially true from the perspective of developing countries, such as Indonesia and Pakistan, where significant portions labour force are dependent on agriculture for their livelihood. paper aims to examine effects macroeconomic policy (i.e. monetary policy) employment, food inflation, agricultural by analysin...

iran has experienced high food prices in recent years. this paper examines the welfare impacts of rising major food groups' prices on iranian urban households using quadratic almost ideal demand system (quaids) approach. the elasticity coefficients derived from quaids are used to estimate compensated variations (cv).the study uses iranian household expenditure and income survey (heis) raw data,...

Growing crops for bio-fuels is often criticized because of its direct competition for land for food production. The recent price increases on world food markets are partly a result of this competition. For instance, cereals prices have increased by more than 60% percent since 2005 and in 2006 sugar prices peaked on a level twice as high as the level of previous years. There are concerns whether...

a r t i c l e i n f o The main purpose of this paper is to identify the effects of exogenous factors, which have been somewhat controversial , on the price links between the energy and agricultural commodity markets. Our study differs from other studies by employing multivariate normal mixture models to capture the structural properties of the price dependencies in the underlying states. This p...

The link (or lack of link) between food commodity prices and consumer prices is an important issue not only for academics but also for policymakers. This paper asks how and to what extent changes in food commodity prices spill over to consumer prices, using a new data set for the euro area as well as a new empirical approach. The authors find that there is a statistically significant link betwe...

the amount of impacts of changes in world prices on economic indices of a country can be studied focusing economy's openness level and volume of the country's interaction with other countries. the increase in world prices in recent years, in one hand and the consistent increase of domestic inflation in the other hand put special importance upon surveying the impacts level of the world...
