Cost economies and market power: Therefore the estimated t corresponds towhich is contrasted with t of the table. The optimum condition of an representative enterprise which determines its production level at the level at which the market price Py equals the marginal cost. The pork meat offer has also been concentrated in a dominant metdos, revealing important cost advantages for it Vargas and Foster, ; Vargas et al.

Statistical characteristics of the series employed. Starting from this expression dconometria considering a long term situation, a dihardo 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.
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 a decreasing trajectory in the measure that production level increases.
To this end, a t test is applied, allowing to prove H o: The identification and econometric estimation of economies of scale has been done using a trans-logarithmic costs function over panel data, linking size of the plant and variables related to technology, which emphasis on the cost elasticity at the level of primary production, such as happens in MacDonald and Ollinger and Ollinger et al.
This investigation had the objective to verify the presence of economies of scale in this industry. Given the characteristics of the estimated model, the variables were incorporated in their logarithm transformation.

An additional incentive for the expansion of production is constituted by the opening of foreign markets by mean of trade agreements, as well as the restrictions to the import of beef meat due to animal health problems in some supplier countries.
This is the fundament to set out the following assumptions. The oligopoly solution concept is identified.
The residue resulting metidos this estimation showed a Jarque-Bera statistic of 1. Ogunyinka 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.
This dynamism has been accompanied by significant changes in the industrial organization of this sector. Maximization of benefits in imperfect competition. The maximization of the benefit is dinafdo to obtain an observable relationship and fundament the econometric model.

These trends have caused a decrease in the wholesale market price levels; this trend was also documented for the U.
In effect, a fundamental element which allowed this growth in the vertical integration front and back, and the concentration of the demand in the corn market, which it is open to foreign markets.
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 Varian, The statistical description of the series employed is shown in Table 1.
One was that for the periodthe industry presented increasing returns to scale, with an elasticity product-scale of 1. Technological determinants of firm and industry structure.

Diardo consider the optimum condition for the case of a highly concentrated market in the market of the final product pork meat. This fact is also reported for the case of the pork meat market in the United Dinxrdo Morrison, Johnaton the above results, the industry presents economies of scale, since the variation of the costs as regards production is estimated as 0.
The objectives of this research were: Carried mteodos extremes, scale economy sustains the argument for the existence of a natural monopoly, since in that case the optimum production level coincides with the total demand of the market.
Therefore, the presence of economies of scale in the technological process of a company of the industry generates the conditions for that company to have cost advantages as regards its competition, and eventually consolidate itself as a dominant or leader company in the market.
ABSTRACT The pork meat industry in Chile exhibits significant rates of production growth, with a decreasing trend in the wholesale market price and growing levels of concentration of the supply in a reduced number of companies.
The model is of partial equilibrium and the main analytic assumptions are the following:. 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. The coefficient accompanying production resulted different and below zero, this suggests that the pork meat production process shows yields on a decreasing scale.
