Abstract

The main objective of this paper is the estimation of market power of the farmed rainbow trout in Iran. For this purpose we do the analysis of the statistical information relating to the MARKETING MARGIN and the amount of the Rainbow trout Pool, the distribution on the market and also the transport and packaging costs Rainbow trout. The period of this paper is between 1986 to 2014. The way of investigating in this paper is the nonlinear least square. After confirming the normality and the absence of serial autocorrelation in the residuals, to resolve the problems of HETEROSKEDASTICITY of regression was used to estimate appropriate weight. finally, after estimating model with appropriate weight and estimating MARKETING MARGIN function, elasticity and expected changing at the retail level and in pools are calculated. The F and Durbin-Watson statistics and the coefficient of determination also represent the appropriateness of the estimated regression model. Results can be expressed as: The effect of transport costs and the production of trout (which will be available in the market) are negative and significant on the MARKETING MARGIN. Rainbow trout production (in the pool) and a significant positive effect on MARKETING MARGIN. As well as the effect of packaging on the cost of MARKETING MARGIN is statistically valid. The amount of market power obtained for the trout ponds and the same product at retail are small although the amount of market power obtained for the trout ponds is far less than the strength in retail sales.
