There is considerable concern and debate about the economic impacts of environmental regulations. Jonathan Fisher, former Economics Manager at the Environment Agency in England and Wales, reviews the available evidence on this subject. Section 2 presents estimates of the costs and benefits of environmental regulations. Section 3 examines the impacts of environmental regulations on economic growth, innovation and technical change as well as impacts on competitiveness and any movement of businesses to less pollution havens. He questions call for greater certainty regarding future environmental regulations, whereas in fact there should be calls for less uncertainty. This section then suggests how this could be achieved. This section then finishes with an overview of the available evidence. This includes an examination of the Porter Hypothesis that environmental regulations can trigger greater innovation that may partially or more than fully offset the compliance costs. Section 4 then sets out principles for how better environmental regulation can improve its impacts on sustainable economic growth and illustrates how the European Union (EU) Water Framework Directive is a good example of the application of these principles in practice. Section 5 reviews current and recent political perspectives regarding developments in environmental regulations across the EU and shows how the United Kingdom (UK) has successfully positively managed to influence such developments so that EU environmental regulations now incorporate many of these principles to improve their impacts on economic growth. Section 5.1 then examines the implications of Brexit for UK environmental regulations. Finally, Section 6 sets out some best practice principles to improve the impacts of environmental regulation on sustainable economic growth, innovation and technical change.

The presumption that R&D is a key driver of economic growth is difficult to reconcile with empirical evidence. For example, in most studies, which identify technical change with total factor productivity (TFP), the link between TFP and measures of knowledge is found to be weak.This paper shows that a reconciliation may be possible in a model where R&D contributes to growth through investment-specific technical change. Such a model predicts that the empirical link between knowledge and productivty would be weak even if the generation of knowledge is the predominant factor of economic growth. The paper also shows that estimates of the production function for knowledge using patent data may be biased.

Economists often conflate the theory of economic development with the theory of economic growth. This practice has become increasingly popular since Robert Solow made elegant improvements to the Harrod–Domar growth model, but left it unclear whether it was meant to be applicable in developing countries. Solow’s model has one sector only and aggregates growth as increased GNP. It has no place for changes in the balance between economic sectors that characterize development. A related technique is growth accounting, which disaggregates growth into amounts generated by capital and labour inputs, and a residual attributed to technical change and all other influences on growth. The finding that the residual outweighs the effect of factor inputs is subject to measurement problems, and ignores the question of large productivity differentials between sectors.

By means of an endogenous growth model of directed technical change with vertical and horizontal R&D, we study a transitional-dynamics mechanism that is consistent with the changes in the shares of the high- versus the low-tech sectors found in recent European data. Under the hypothesis of a positive shock in the proportion of high-skilled labor, the technological-knowledge bias channel leads to unbalanced sectoral growth with a noticeable shift of resources across sectors. A calibration exercise suggests that the model is able to account for up to from 50 to about 100 percent of the increase in the share of the high-tech sector observed in the data from 1995 to 2007. However, the model predicts that the dynamics of the share of the high-tech sector has no significant impact on the dynamics of the economic growth rate.
