This paper analyses two aspects of environmental regulations triggered by ecoinnovations. First, whether there are long term effects of regulation on innovation. Second, whether the impact of different types of regulation differ by type of the environmental benefit of the innovations. To answer...

We examine impacts of different types of environmental innovations on firm profits. Following Porter's (1991) hypothesis that environmental regulation can improve firms' competitiveness we distinguish regulation induced and voluntary environmental innovations. We find that innovations which...

The performance of market based environmental regulation is affected by patents and vice versa. This interaction is studied for a new type of innovation where new technologies reduce emissions of a specific pollutant but at the same time cause a new type of damage. A robust finding is that the...

The literature on environmental R&D frequently studies innovation as a two-stage process, with a single R&D event leading from a conventional polluting technology to a perfectly clean backstop. We allow for uncertainty in innovation in that the new technology may turn out to generate a new...

This survey reviews the empirical literature on the impact of environmental policy instruments on the rate and direction of technological change. The survey is explicitly focused on the empirical identification of the hypothesis to expect a stronger impact from market-based incentives than from...

Die vergleichende Analyse umweltpolitischer Instrumente kommt regelmäßig zu dem Ergebnis, dass Emissionsabgaben einen höheren Innovationsanreiz auslösen als Emissionsauflagen. Demgegenüber weisen neuere Studien der empirischen Innovationsforschung auf keine eindeutige Rangfolge zwischen den...

It has long been argued that the implementation of market-based environmental policy instruments such as environmentally-related taxes and tradable permits is likely to lead to greater technological innovation than more direct forms of regulation such as technology-based standards. One of the...

Since governments can influence the demand for a new abatement technology through their environmental policy, they may be able to expropriate innovations in new abatement technology ex post. This suggests that incentives for environmental R&D may be lower than the incentives for market goods...

The pollution haven hypothesis affirms that an open market regime will encourage the flow of low technology polluting industries toward developing countries, due to potential comparative advantages related to low environmental standards. In contrast, the hypothesis suggested by Porter and van...

The paper looks at a model of directed technical change in an environmental-economics context. Firms can do conventional or 'green' R&D or they can abate emissions at the end of pipe. The paper has two main foci. On the one hand, it investigates the impact of environmental regulation on the...
