Abstract

To explicitly explain the cost-reducing effects of technical progress experienced by each firm, we assume that technical progress, namely, the prevalence of particular equipment, can be expressed by a function of logarithmic physical capital. Regarding the technology cost structure, we propose a modified dynamic cost function model that consists of the above equation, the translog variable cost equation containing technical progress as one of the factors, and Euler equations with respect to physical and research and development capital stocks. Using data on eight firms in the Japanese electric-furnace steel industry for the period 1970–1998, the model was empirically validated using the generalized method of moments. An elasticity of production cost with respect to technical progress showed a cost-reducing effect. This fact was influenced by the type of product and the extent of each firm’s R&D. Also derived from this model is one reasonable phenomenon of business-cyclically changing the use of endogenous capacity. This economic information supports the appropriateness of the above model, including the assumption of transforming technical progress into an endogenous variable, and the methods of analysis.

  1. See Sect. 2.

  2. The iron- and steel-making industries in Japan can be divided into two main groups. One of these is an integral iron and steel industry that specializes in mass production, while the other is an electric-furnace steel-making industry that deals primarily with large items that are typically produced on a small scale.

  3. In the period considered in this study, blast furnace manufacturers in Japan were represented by four leading firms, in which the production and marketing administration could be managed in a similar manner because there were few differences in the types of product and the efficiency of production. In contrast, the electric-furnace manufacturers could be divided into three groups by the type of steel that they exclusively produced and there were large differences among these groups with respect to the efficiency of production and the opportunity of equipment investment.

  4. To avoid the possibility of multicolinearity during the estimation, we omitted the square of K and the cross term between CCR and R from the cost function G.

  5. Recently, the AB method (Arellano and Bond 1991) has been recommended for the estimation of models in which lagged dependent variables are used as explanatory variables in rental and adjusting costs within the Euler equations. We attempted to use the AB method to estimate the model using 2- and 3-year lagged instrumental variables of rental cost and adjusting cost with respect to physical capital K, and R&D capital R. However, no stable results were obtained. It was difficult to obtain reliable values for the parameters because the use of six equations did not allow for model estimation in comparisons of eight samples (i.e., firms), despite the 29 years of data. We considered that the necessity of using the AB method should be low in the case of such panel data.

  6. In this research, we use a function that is non-linear in time, i.e., a translog-type function. Therefore, we believe that the time trend should also be written as approximately quadratic. First differencing results in the exclusion of the constant term B 0 and the first time-trend term B t t t from the variable cost function. In addition, the constant term A 0 is added to the differenced variable cost equation.
