This paper provides an overview of the treatment of technological change in economic models of environmental policy. Numerous economic modeling studies have confirmed the sensitivity of midand long-run climate change mitigation cost and benefit projections to assumptions about technology costs. In general, technical progress is considered to be a noneconomic, exogenous variable in global climat...

This paper introduces dynamics in the R&D to innovation and innovation to productivity relationships, which have mostly been estimated on cross-sectional data. It considers four nonlinear dynamic simultaneous equations models that include individual effects and idiosyncratic errors correlated across equations and that differ in the way innovation enters the conditional mean of labor productivit...

Environmental regulation is increasingly judged on its ability to stimulate innovation. While prior studies focus primarily on the direct effect on innovation by regulated firms, this paper examines the importance of indirectly induced innovation by both regulated and unregulated firms. Two channels for indirect effects are considered: passthrough of regulation-imposed costs into output prices ...

In this paper we study the welfare effect of a monopoly innovation. Unlike many partial equilibrium models carried out in previous studies, general equilibrium models with non-price-taking behavior are constructed and analyzed in greater detail. We discover that technical innovation carried out by a monopolist could significantly increase the social welfare. We conclude that, in general, the cr...

Innovation is the major instigator in competitive industry. The competition for innovation is traditionally analyzed within the framework of deterministic and stochastic models (Reinganum, 1989). Boone (2001), Fethke and Birch (1982) have respectively analyzed the standard models of competitive strategies in a duopoly and oligopoly industry. By focusing our analysis on deterministic models that...

This paper provides a systematic methodology to identify general innovation diffusion patterns in a given case study: First, an analytical framework is introduced which structures a review of innovation diffusion research. This framework may be used to structure the analysis of a case study. Second, a classification of innovation diffusion models is developed by focusing on the analytical hypot...

This study models the evolution of technology innovation network. Results argue that the growth of hybrid rice innovation network fellows S-curve by time; the innovation network fits preferential attachment as amended aging Lognormal distributions. And it implies that the degree distribution of the technology innovation network follows a power law distribution.
