Maximization of benefits in imperfect competition. The coefficient accompanying production resulted different and below zero, this suggests that the pork meat production process shows yields on a decreasing scale.

The unit root test was applied in this manner. The objectives of this research were: Mercado de la carne de cerdo. We consider the optimum condition for the case of a highly concentrated market in the market of the final product pork meat. The model is of partial equilibrium and the main analytic assumptions are the following: We consider the optimum condition for the case of a highly concentrated market in the market of the final product pork meat. Market structure, scale economies and industry performance.

This fact is also reported for the case of the pork meat market in the United States Morrison, The result is shown in Table 2. If a company shows yields in a growing scale of econometra technology and the perfect information conditions are not present, this company can increase its participation in the market and in this way modify the structure of it, as is argued by Panzar and Amir This functional form is flexible and, under determined restrictions on its coefficients, can represent several functional forms and can be applied to multi-product enterprises.

This investigation had the objective to verify the presence of economies of scale in this industry. These results suggest that the utilization of the factors in econoemtria industry is found in the rational steps, according to the theory of production, that is, the concave zone of the production function, where the benefit of the enterprise is positive.

There are also export quotas towards markets with which Chile has subscribed trade agreements, thus generating important business opportunities for this industry. In this context, the average production cost decreases while the production level increases, up to a certain limit.

The optimum condition of an representative enterprise which determines its metodls level at the level at which the market price Py equals the marginal cost. In this way, there is a direct observation of the marginal cost through the market price of pork meat.

In this last case, the series has constant variance when, in absolute terms, the statistic of Dickey-Fuller Augmented DFA Johnston and Dinardo, calculated is higher than that tabulated. Given the characteristics of the estimated model, the variables were incorporated in their econometrja transformation. There are also export quotas towards markets with which Chile has subscribed trade agreements, thus generating important business opportunities for this industry.

Given the above results, the industry presents economies of scale, since the variation of the costs as regards production is estimated as 0.

Estimación de Economías de Escala en la Industria de la Carne de Cerdo en Chile

One was that for the periodthe industry presented increasing returns to scale, with an elasticity product-scale of 1. On the other hand, Coffey and Featherstone employ non-parametric techniques to estimate scale economies with crossed section data, fundamentally because it is not necessary to restrict the technology employed to a specific functional form.

This fact is also reported for the case of the pork econometrja market in the United States Morrison, Starting from this expression and considering a long term situation, economwtria technology shows yields in a growing scale when the sum of the exponents accompanying the variables labor and capital is greater than one, so that said technology shows economies of scale. This shows that the industry shows yields on a growing scale. The true process sustaining the behavior of the port meat industry is its deep technological transformation, supported by the behavior of decreasing corn prices, a most important supply for pig feeding; this has taken place mainly since It was concluded that this industry shows conditions meyodos increase its advantage in costs and of expanding its competitiveness in international markets.

Industria de la carne de cerdo. One of the theoretical conditions for a market to respond to competition conditions is that the technology present in the industry should show yields at constant rates, both for the factors market as well as for the end product, since the companies will produce their optimum economic level in such quantities as will not have an influence in the balance Jonston, The model is of partial equilibrium and the main analytic assumptions are the following:.

Real interest jognston placements 1 to 3 years, yearly average. This investigation had the objective to verify the presence of economies of scale in this industry. To this end, a t test is applied, allowing to prove H0: The AR 1 factor allows the introduction into the model of the systematic part which links the residues in t and t-1, generating a new econometrai term which complies with the assumptions of the classic model. An indirect way of estimating the coefficients of function 1 is by the estimation of the costs function obtained from the Cobb-Douglas technology, more specifically, by means of the ecoometria costs function, since this is expressed in terms of the price of the factors and the level of the production.

Johnxton and Featherstone arrive at this same conclusion after estimating a generalized Box-Cox production cost model, applied to agricultural products and raw materials in the United States.

The pork meat offer has also been concentrated in a dominant company, revealing dinard cost advantages for econonetria Vargas and Foster, ; Vargas et al. On the other hand, given the product-factor elasticity found, it can be stated that the process aggregate is more capital-intensive.

On the choice of functional forms in the measurement of scale and scope economies: Analyzing algebraically according to expression 2 in individual terms, the product-labor elasticity resulted as 0.

These trends have caused a decrease in the wholesale market price levels; this trend was also documented for the U. Then, the model to be estimated can be specified as: To this end the model was estimated with the Cochrane-Orcut correction Johnston y Dinardo,to attenuate the effect of the autocorrelation in the residues of the model. If it is positive, the technology shows yields on a economeetria scale, and if it is statistically equal to zero, jkhnston suggests a constant scale of yield.

One was that for the periodthe industry presented increasing returns to scale, with an elasticity product-scale of 1.

This is important in terms of competitiveness of the sector, as the mean costs follow metodoos decreasing trajectory in the measure that production level increases. The result is shown in Table 2. Estimating model result for period The structural element dinado sustains concentration and expansion of the production is the presence of increasing returns to scale in the production process.

In the present work, the interest is centered in the exponent accompanying the production level, as it reflects the type of yield to scale present in the pork meat production process.

Now, we can state that the market price of pork meat Py is equal to the marginal cost CMga condition of the first order for the maximization of the benefit. Estimation of the econometric model The estimated model considered controlling meodos autocorrelation of the residues and the presence of unit root in the variables considered.

In the present work, the interest is centered in the exponent accompanying the production level, as it reflects the type of yield to scale present in the pork meat production process.

This is important in terms of competitiveness of the sector, as the mean costs follow a decreasing trajectory in the measure that production level increases.
