the agricultural products’ market has always been faced with many structural problems such as marketing weakness, price fluctuations and inadequate infrastructure and transportation in iran. a major cause of such structural problems has been referred to the traditional and inefficient structure of the agricultural products’ market. hence, iran mercantile exchange started its activity since 2007...

Analysis of the characteristics of agricultural product price volatility and trend forecasting are necessary to formulate and implement agricultural price control policies. Taking wholesale cabbage prices as an example, a multiple test methodology has been adopted to identify the nonlinearity, fractality, and chaos of the data. The approaches used include the R/S analysis, the BDS test, the pow...

The response of agriculture to changes in relative prices is an important factor in the success of structural adjustment programs in Africa. In this paper I estimate supply functions for total agricultural output, food crops and export crops in 14 African countries for the years 1975 to 1990. Food and export crops are substitutes in production in the short run. Total agricultural output respond...

 Growth in the productivity of staple nontradable food production is associated with consumption increases or poverty reduction across a number of settings, although the study of these relationships is complicated by the specific market dynamics that determine food prices. The relationship between productivity growth in tradable or export-oriented production and poverty alleviation is less cle...

Advances in nonlinear dynamics have resuscitated interest in the theory of endogenous price fluctuations. In this paper, we enrich the traditional cobweb model by incorporating vertical linkages between agricultural markets, an important aspect of agricultural production in less developed countries that has been largely ignored by the existing literature on chaotic cobweb models. To this end, u...

Farmers earn their main income from selling agricultural commodities. Stabilityas well as the level of income are determined by the amount of production and marketprices. Prices and price policies on the agricultural market could have a great impact onthe success of programmes themselves. This paper focuses on research of relationshipsbetween prices at the regional level. The ai...

This paper develops a Tobin’s q model of house prices which shows that changes in interest rates, demography, and income are likely to have only temporary effects on house prices while house prices in the long run are determined by prices of developed land, value added taxes, stamp duties, and construction costs. Empirical estimates show that agricultural land prices are a proxy for urban land ...

Agricultural commodity futures prices play a significant role in the change tendency of these spot prices and the supply–demand relationship of global agricultural product markets. Due to the nonlinear and nonstationary nature of this kind of time series data, it is inevitable for price forecasting research to take this nature into consideration. Therefore, we aim to enrich the existing researc...

In recent years, food security, especially supply, has been an important issue in China’s agricultural production. The stability of grain prices is related to the stability and development of the grain market. Based on agricultural production data from 1970 to 2015, this paper explores the influence of agricultural product price fluctuation on grain production by using the cobweb theory and vec...

oil prices may be having a direct and indirect effect through the exchange rate on the price of agricultural commodities. in this paper, the impact of world oil prices and exchange rate shocks on prices of specific agricultural commodities including wheat, corn, soybeans and sunflowers in iran is discussed. for this purpose, vector autoregressive model with monthly data over the period 2010-199...
