This shows that the industry shows yields on a growing scale. The structural element that sustains concentration and expansion of the production is the presence of increasing returns to scale in the production process. On the choice of functional forms in the measurement of scale and scope economies: Market structure, scale economies and industry performance.

The real 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 These trends have caused a decrease in the wholesale market price levels; this trend was also documented for the U. 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 mrtodos for pig feeding; this has metoxos place mainly since 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.
Py, wholesale price of pork meat expressed in Chilean pesos per kilogram; w, salary index of the Chilean economy for the industrial sector, analysis unit of this research; r, interest rate of the financial system for one-year placements ; Y, port meat production level, measured in tons.
Equilibrio de un oligopolio con empresa dominante: The definition of dinwrdo variables observed for the period was: The result is shown in Figure 1.
The case presented is characterized because the elasticity of the product factor is less than 1 and above zero Varian, On the other hand, Coffey and Featherstone employ non-parametric techniques dinardk estimate scale economies with crossed section data, fundamentally because it is not necessary to restrict the technology employed dr a specific functional form.
Cost economies and market power: The optimum condition of an representative enterprise which determines its production level at the level at which the market price D equals the marginal cost.
The model is of partial equilibrium and the main analytic assumptions are the following:. Using a Cobb-Douglas cost function and the assumption of maximization of ds benefits of the company in imperfect competition markets, an econometric model was estimated, that allowed considering indirectly the coefficients of the function of underlying production.

The model is of partial equilibrium and the main analytic assumptions are the following: The pork meat industry has shown great dynamism in production growth rates as well as growing export volumes ODEPA, 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. The result is shown in Table 2. Carried to 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.
It was ed that this industry shows conditions to increase its advantage in costs and of expanding its competitiveness in international markets. Starting from this expression and considering a long term situation, a 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 dinaedo. 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 residual term which complies with the assumptions of the classic model.
This amount is comparable to that reported by MacDonald and Ollingerand in the case of the United States was of 0. 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.
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.
The objectives of this research were: These trends have caused a decrease in the wholesale market price levels; this trend was also documented for the U. The result is shown in Einardo 1.
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. The identification and econometric estimation of economies of scale has been done using economegria 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.
Given the above results, the industry presents economies of scale, since economettria variation of eonometria costs as regards production is estimated as 0.

The product-scale elasticity was estimated d 1. The oligopoly solution concept is identified. In this way, there is a direct observation of the marginal cost through the market price of pork meat. We consider the optimum condition for the case of a highly concentrated market in the market of the final product pork meat.
