t he objective of this study is using the markov switching vector autoregressive method and regime dependent impulse response functions to measure the pass-through of world food prices to consumer price index in iran from 1990 to 2013. with respect to information criteria and the log-likelihood ratio statistic, msia(2)-var(1) model has a better fit to data than other models. the magnitude of th...

We revisit the cost of the U.S. sugar program by analyzing the welfare implications of its removal. We use a multimarket model of U.S. sweetener markets, which includes raw crops, sugar extraction and refining, high-fructose corn syrup, and sweetener users (food-processing industries and final consumers). Our approach addresses the industrial organization of food industries using sweeteners and...

In this paper we use the frequency domain Granger causality test of Breitung/Candelon (2006) to analyse short and long-run causality between energy prices and prices of food commodities. We find that the oil price Granger causes all the considered food prices. However, when controlling for business cycle fluctuations this link exists especially at low frequencies. Thus, short-run phenomena like...

Food commodity price fluctuations have an important impact on poverty and food insecurity across the world. Conventional models have not provided a complete picture of recent price spikes in agricultural commodity markets, while there is an urgent need for appropriate policy responses. Perhaps new approaches are needed in order to better understand international spill-overs, the feedback betwee...

As public intervention is a pervasive influence on food prices, this paper asks whether and how the inefficiency of state institutions matters to food prices. In the context of the wheat subsidy scheme in India, the paper models the implications of quality differences between public and private grain supply. As both are procured at similar prices, the lower quality of public grain marks the ine...

This paper proposes a price index for artists based on the ratio between the average market price and the average estimated price of the paintings sold by an artist each year, adjusted for market dynamics. We apply this methodology to a group of selected artists and schools drawing from a database including auction prices and estimated prices of paintings presented in auctions world wide betwee...

Rational junk-food consumption is analyzed within an expected lifetime utility maximizing framework in which longevity and productivity rise with health, and health deteriorates with junk-food consumption. As long as the junk food’s relative taste-price differential is positive, the consumer’s rational diet deviates from the physiologically optimal one and generates lower than maximal levels of...

on one hand, oil is the greatest energy resource in the world and, on the other hand, because of the role of oil revenue in the economic of oil producer countries, such as iran,it is vital for these countries. so it is necessary to recognize different affective parameters on oil market for these countries. in this research, we try to forecast oil price as an important variable in world wide oil...

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...
