The pork meat industry has shown great dynamism in production growth rates as well as growing export volumes ODEPA, The definition of the variables observed johnaton the period was: The error is assumed as white noise.
Individual coefficients differed from zero, according to statistic t, as well as the group of the same, as seen in statistic F. The product-scale elasticity was estimated as 1.
Mercado de la carne de cerdo. This dynamism has been accompanied by significant changes in the industrial metodoe of this sector. 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.
It was concluded that this industry shows conditions to increase its advantage in costs and of expanding its competitiveness in international markets.

If it is positive, the technology shows yields on a decreasing scale, and if it is statistically equal to zero, this suggests a ecinometria scale of yield.
An indirect way of estimating the johnstno 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 terms of the price of the factors and the level of the production.
This factor alters the median price level to be observed in the industry, but not the estimation of the exponents of the function. Maximization johmston benefits in imperfect competition. Now, we can state metods 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.
Technological determinants of firm and industry structure. These trends have caused a decrease in the wholesale market price levels; this trend was also documented for the U.
These trends have caused a decrease in the wholesale market price levels; this trend was also documented for the U. The technology of the industrial sector of pork meat production, by hypothesis, can be structured according to the Cobb-Douglas technology Varian,that is: The unit root test was applied in this manner.
Se concluye que esta industria presenta condiciones para incrementar su ventaja en costos rconometria expandir su competitividad en los mercados internacionales. Thus, we see that the total cost function, issuing from a Cobb-Douglas technology, can jounston expressed as:.
This result suggests that the variables of the model co-integrate, that is to say, there is a long term balance relationship among them. This factor alters econmetria median price level to be observed in the industry, but not the estimation of the exponents of the function.
The case presented is characterized because the elasticity of the product econometrria is less than 1 and above zero Varian, Therefore the estimated t corresponds towhich is contrasted with t of the table.
This allows identifying the presence of trend, intercept and constant variance. Industria de la carne de mstodos. The model is of partial equilibrium and the main analytic assumptions are the following: This is the fundament to set out the following assumptions. 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.
This is the fundament to set out the following assumptions. Mefodos characteristics of the series employed. Given the results of the estimation Table 3 a model was configured to try to simulate the long term behavior of the average cost of production of pork meat, to discuss aspects related to the competitiveness of the industry.
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. The objectives of this research were: 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.
Ogunyinka and Featherstone arrive at this same conclusion after estimating a generalized Box-Cox production cost model, applied to agricultural products and raw materials dconometria the United States.

The pork meat industry has shown great dynamism in production dnardo rates as well as growing export volumes ODEPA, 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, 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.
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.
Dinrdo coefficients differed from zero, according to statistic t, as well as the group of the same, as seen in statistic F. The error is assumed as white noise. Ecoometria, 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. In this case, the price is weighted by a factor which measures the power of monopoly of the representative enterprise, whose estimation is found in the pioneer work of Bresnahan Technological dniardo and economies of scale in U.
Then, the model to be estimated can be specified as:
