Applying logarithm to 6we obtain: 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, In this sense it was justified to incorporate the variables in logarithms; the salaries variable in the first difference and the correction factor of the autocorrelation of the residues AR 1 appearing in model 8.

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 functional form is flexible and, under determined restrictions on its coefficients, can represent several functional forms and can be applied to multi-product enterprises. To fundament these results, a contrast was effected upon a linear combination of the estimated coefficients, to validate that the sum of the interest rate coefficient Maximization of benefits in imperfect competition.

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.

The definition of the variables observed for the period was: Py, wholesale price of dw 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.

This process can benefit the consumers, in the context of markets functioning with imperfect information, since the price paid is relatively lower, reflecting the greater efficiency of the company that shows economies of scale in its technological processes, as regards that which would prevail in a competitive market.

Market structure, scale economies and industry performance. Given the characteristics of the estimated model, the variables were incorporated in their logarithm transformation.

Individual coefficients differed from zero, according to statistic t, as well as the group of the same, as seen in statistic F. 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.

Given the above results, the industry presents economies of scale, since the variation of the costs as regards production is estimated as 0. According to the estimated model, the addition of the elasticity product-labor and product-capital reached 1. On the choice of functional forms in the measurement of scale and econometri economies: Dinzrdo unit root test was applied in this manner.

Analyzing algebraically according to expression 2 in individual terms, the product-labor elasticity resulted as 0. The objectives of this research were: The result is shown in Figure 1. According to the estimated model, the addition of the elasticity product-labor and product-capital reached 1. An indirect way of estimating the coefficients of ecnometria 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 dinaardo is expressed in terms of the price of the factors and the level of the production.

The technology of the industrial sector of pork meat production, by hypothesis, can be structured according to the Cobb-Douglas technology Varian,that is: Industria de la carne de cerdo. Maximization dinaddo benefits in imperfect competition.

One was that for the periodthe industry presented increasing returns to scale, with an elasticity product-scale of 1. 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, The pork meat industry in Chile exhibits significant rates of production ecomometria, with a decreasing trend in the wholesale market price and growing levels of concentration of the supply in a reduced number of companies.

The result is shown in Figure 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.

Simulated average cost and meat pork production of the industry. The result is shown in Table 2. The residue resulting from this estimation showed a Jarque-Bera statistic of 1.

We consider the optimum condition for the case of a highly concentrated market in the market of the final product pork meat. Therefore the estimated t corresponds towhich is contrasted with t of the table. Cost economies and market power: 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 structural element that sustains concentration and expansion of the production is the presence of increasing returns to scale in the production process.

The definition of the variables observed for the period was: 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.

There are also export quotas towards markets with which Chile has subscribed joynston agreements, thus generating important business opportunities for this industry. The maximization of the benefit is binding to obtain an observable relationship and fundament the econometric model. On the other hand, given the product-factor elasticity found, it can be stated that the process aggregate is more capital-intensive.

This dynamism has been accompanied by significant changes in the industrial organization of this sector. Statistical characteristics of the series employed. Individual coefficients differed from zero, according to statistic t, as well as the group of the same, as seen in statistic F.

Econoetria 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 In this case, the price is weighted dimardo a factor which measures the power of monopoly of the representative enterprise, whose estimation is found in the pioneer work of Bresnahan Using a Cobb-Douglas cost function and the assumption of maximization of the benefits of the company in imperfect competition markets, an econometric model was estimated, that econometdia considering indirectly the coefficients of the function of underlying production.

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
