one of the import indices of food security evaluation is food import capacity index. ratio of total exports to food imports is often thought to be a measure of the capacity of a country to finance its food imports using revenues from exports of goods and services. this study investigates food import capacity effects on rural households food security by calculated ahfci (aggregate household food...

according to amount of oil seeds import in iran are more than 80% of domestic needs, in this study, import comparative advantage in soybeans using rca and rsca index is calculated in 1961-2008 periods for iran and ten important importer countries. iran’s competition state is investigated. also long run relation between production and import comparative advantage index is estimated using johanse...

This paper investigates the behaviour of Indian aggregate imports during the period 1971-1995. In our empirical analysis of the aggregate import demand function for India, cointegration and error correction modelling approaches have been used. In the aggregate import demand function for India, import volume is found to be cointegrated with relative import price and real GDP. Our econometric est...

The level of price volatility should theoretically be confined to export parity price levels at the lower end and import parity price levels at the upper end of the price band, reflecting supply and demand conditions during surplus and deficit marketing seasons respectively. A greater gap between these export and import parity prices will reflect high marketing costs, often representing high tr...

In closed or open economy models with complete markets, targeting core inflation enables monetary policy to maximize welfare by replicating the flexible price equilibrium. We analyze this result in the context of developing economies, where a large proportion of households are credit constrained and the share of food expenditures in total consumption expenditures is high. We develop an open eco...

A drastic change in the marketing system of wheat in South Africa has taken place over the past decade. For the first time an import tariff on wheat was implemented in the form of a variable import levy. Traditionally, countries have implemented variable import levy schemes in order to protect domestic price guarantees by means of determining a reference price, which was generally above the dom...

We determine how the U.S. ethanol tax credit and import tariff affect the corn-ethanol-gasoline markets and how farm subsidies interact with these policies. We show how the ethanol tax credit and import tariff each uniquely affect the ethanol and gasoline prices. The ethanol import tariff alone increases the terms of trade in ethanol imports and corn exports, but decreases the terms of trade in...

Rice comes second after wheat in Iran`s food consumption economy. However Iran is one of the greatest rice importer countries all over the world because of its rising population and recent growth in GDP. This paper presents an analysis of cointegration test between rice import and it`s economic factors over the period 1990-2011, employing Engle-Granger model. At first, Dickey-Fuller test shows ...

A model of the Iranian wheat market is specified and fitted to data from 1981-2008. Severaldiagnostic tests were employed in the analysis to determine the specification of the model. Despitethe simplicity of the model and data problems, an examination of the econometric model leads toseveral conclusions with possible important policy implications for the wheat economy in Iran.The general result...
