We formulate a variable cost function model in which certain inputs are treated as quasi-fixed, and develop a simple statistical test of whether optimization occurs for the quasi-fixed inputs. It is shown how to retrieve characteristics of the long-run cost function from the variable cost...

The objectives of this preliminary study are threefold. The first is to analyze empirically the production structure of the Bell System at the aggregate level. Particular attention is focused on the pattern of substitution among the factor inputs and the degree to which the aggregate production...

This paper proposes a framework which integrates convex costs of adjustment and expectations formation in the determination of investment decisions in R&D at the firm level. The model is based on cost minimization subject to the firm's expectations of the stream of output and the price of R&D,...

This paper provides a statistical test to assess the adequacy of static equilibrium models. The test is based on a restricted cost function framework together with the envelope conditions which characterize static equilibrium for the quasi-fixed factors. We also show how restricted cost function...

The international price linkage in a single commodity model can be explained trivially by the law of one price or the quantity theory of money. In this paper, we formulate a simple sectoral, general equilibrium model with money. The transmission of price pressures from the world market to...

Prucha and Nadiri (1982,1986,1988) introduced a methodology to estimate systems of dynamic factor demand that allows for considerable flexibility in both the choice of the functional form of the technology and the expectation formation process. This paper applies this methodology to estimate the...

In this paper, we examine the sources of the productivity growth in the U.S. computer industry from 1978 to 1999. We estimate a joint production model of output quantity and quality that distinguishes two types of technological changes: process and product innovations. Based on the estimation...

This paper formulates a multiproduct structural model to examine the evolution of the structure of production and demand and the dynamic interaction between the two in the context of the U.S. telecommunications industry over an extended period, from 1935 to 1987. We estimate the degree of scale...

In this paper we examine the effects of publicly financed infrastructure and R&D capital on the cost structure and productivity performance of twelve two-digit U.S. manufacturing industries. A general framework is developed to measure contribution of demand, relative input prices, technical...
