Abstract
Volatility and instability of inputs price and products on the one hand and high marketing margins, on the other hand are the main characters of inefficient marketing of agricultural products. So in this paper we will consider the Prices Transmission of Inputs and Marketing Costs on Marketing Margin of Fisheries Products during 2004 to 2014. The variables examined in this study which were extracted from the website of Fisheries and Statistics Center of Iran, include hot and cold water fish prices (Larve and Fingerling), Fishmeal and Concentrate (inputs), transport and labor costs and amount of used inputs. The results show that Necessary and sufficient conditions for coincidence of inputs price transmission has rejected and mediators through asymmetrical transmission of input prices to retails increase marketing margin and thereby earn profits. The coincident test also in the transfer of marketing costs showed asymmetry coincidence of marketing costs. The variable of total amount of inputs that is considered as an explanatory variable to ensure assume constant returns to scale in marketing margin model, Its impact on marketing margins is incremental and statistically significant. The process trend variable coefficient also shows that market margins will increase over time. To improve this situation it is suggested to establish the Notification institutions of market.
Highlights
1.1 Introduce the ProblemStudy the marketing margin and price transmission have always been attractive in the food chain for researchers and agricultural economists and it is used to analyze the efficiency and utilize the market structure
In this period of time marketing margin growth for warm water fish, cold-water fish, fishmeal and concentrate on average were 7.84, 7.03, 12.61 and 17.45 percent respectively. Comparison of this growth with moderate inflation rate shows that the increase in marketing margin of fisheries inputs has been less than inflation rate in this period
In terms of marketing costs variables the results show that the increase in the cost of marketing indicator is positive which represents an increase of marketing expenses is directly related to marketing margin and reduction variable of marketing Costs expenses which is appeared with negative sign, Demonstrates that the decrease in marketing costs will decrease market margins and the differential of decrease in marketing costs is statistically significant
Summary
1.1 Introduce the ProblemStudy the marketing margin and price transmission have always been attractive in the food chain for researchers and agricultural economists and it is used to analyze the efficiency and utilize the market structure. That the average of wholesale prices of the north fish, south fish and farmed fish (warm and cool water fish), reached respectively from 12574.6, 12418.2 and 10 741 in 2004 to 76 106, 43 390 and 54 445 rials reached in 2014 and the average retail price of 15837.6, 15860.9 and 13198.8 rials in 2004 reached to 82504.3, 106072 and 61975 rials in 2014. Study the price paid by the final consumer with regard to the above figures show that the number of North fish, South fish and the farmed in 2004, are 20.6, 21.7 and 18.6 percent to 7.7, 59 and 12.1 percent in 2014, respectively. In 2014 about 7.7, 59 and 12.1 percent of the price paid by the final consumer (retail level) was the share of the marketing margin (Statistical Yearbook of the Iranian Fisheries Organization, 2014)
