The purpose of this paper is to develop and estimate a model of production with endogenous technological change. Technological change arises from R&D capital accumulation decisions. These decisions respond to market and government incentives and generate R&D capital spillovers. A spillover...

This paper is an attempt to assess the contribution of R&D to growth of output in U.S. manufacturing industries. The important issues to address are: whether the slower growth of R&D expenditures in recent years has been the cause of slowdown in the growth of productivity, and what the factors...

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...

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 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...

In this stuy a dynamic model of firm behavior is developed which integrates real and financial decisions. The model combines the effects of capital structure and input adjustirent costs on the process of capital accumulation. The existence, uniqueness and stability conditions of the long-run...

We estimate and compare the production structures of the US, Japanese, and Korean total manufacturing sectors for the 1974-1990 period. We employ a translog variable cost function that includes such inputs as labor, materials, physical and R&D capital with the physical and R&D capital treated as...

Numerous studies on production and cost, the sources of productivity and studies on endogenous growth have recognized the pivotal role of the physical capital stock. Also there is a clear recognition by economists and policy makers that knowledge capital approximated by R&D capital is crucial...
