What determines the speed of the technology diffusion? What are the consequences of diffusion? This paper presents a model to address these questions. Skilled machine-users adopt a new technology first, while unskilled users wait until machines become more reliable and accessible. The quality...

This paper presents a dynamic partial equilibrium model that endogenizes firms' investment decision on innovation: product innovation causes horizontal expansion growth, and process innovation causes vertical expansion growth. Market structure in different markets emerges as a consequence of...

This paper formulates dynamic R\&D investment decisions of private firms as an optimal stochastic control problem. It derives explicitly R\&D investment decision rule and the cross equations parameter restrictions imposed by the rational expectations hypothesis, using the Riccati equations only...

A growth model with endogenous innovation and accumulation of high-tech and low- tech human capital is developed. The model accounts for a recently established fact about human capital composition, which stated that \the richest countries are investing proportionally less than middle income...
