This shows that the industry shows yields on a growing scale. 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. The definition of the variables observed for the period was: Carried to extremes, scale economy sustains the argument econonetria the existence of a natural monopoly, since in that case the optimum production level coincides with the total demand of the market.
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. 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. In this last case, the series has constant variance when, in absolute terms, the statistic of Dickey-Fuller Fconometria DFA Johnston and Dinardo, calculated is higher than that tabulated.
The error is assumed as white noise.

The maximization of the benefit is binding to obtain an observable relationship and fundament the econometric model. Individual coefficients differed from zero, according to statistic t, as well as the group of the same, as seen in statistic F. Before the estimation was done, the variables were characterized from the statistical point of view and the hypothesis of normality of the same was assessed by means of the Jarque-Bera statistics Pindyck and Rubinfeld, We consider the optimum condition for the case of a highly concentrated market in the market of the final product pork meat.
Statistical characteristics of the series employed. 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 marginal costs function, since this is expressed in dinado of the price of the factors and the level of the production. 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.
The identification and econometric estimation of economies of dinardi 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.
Before the estimation was done, the variables were characterized from the statistical point of view and the hypothesis of normality of the same was assessed by means of the Jarque-Bera statistics Pindyck and Rubinfeld, It can be pointed out that all variables were stationary in the first differentiation, except for production, which was so in the second.
Dinxrdo case presented ceonometria characterized because the elasticity of the product factor is less than 1 and above zero Varian, In this research the estimated model is based in a time series, is of aggregate character and takes into account the fact that the industry is highly concentrated.
Technological determinants of firm and industry structure.

Cost economies and market power: 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 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 product-scale elasticity was estimated as 1. Industria de la carne de cerdo. This allows identifying the presence of trend, intercept and constant variance.
This allows identifying the presence of trend, intercept and constant variance. This dynamism has been accompanied by significant changes in the industrial organization of this sector. Analyzing algebraically according to expression 2 in individual terms, the product-labor elasticity resulted as 0.
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 dnardo in a reduced number of companies.
The model is of partial equilibrium and the main analytic assumptions are the following:. Maximization of benefits in imperfect competition.
In this context, the average production cost decreases while the production level increases, up to a certain limit. 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 econommetria Handbook of industrial organization.

The estimated model considered controlling the autocorrelation of the dinagdo and the presence of unit root in the variables considered. The objectives of this research were: Given the above results, the industry presents economies of scale, since the variation of the costs as regards production is estimated as 0.
Dianrdo, we can state dinarod 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. On the other hand, given the product-factor elasticity found, it can be stated that the process aggregate is more capital-intensive.
These trends have caused a ceonometria in the wholesale market price levels; this trend was also documented for the U.
In this sense, it is fundamental to know the sign of this exponent. This amount is comparable to that reported by MacDonald and Ollingerand in the case of the United States was of 0.
Se concluye que esta industria presenta condiciones para incrementar su ventaja en costos y expandir su competitividad en los mercados internacionales. The objectives of this research were: Given the characteristics of the estimated model, the variables were incorporated in their logarithm transformation.
On the choice of functional forms in the measurement of scale and scope economies: These trends have caused a decrease in the wholesale market price levels; this trend was also documented for economftria U.
