Environmental regulations and innovation activity in UK manufacturing industries

We examine the relationship between environmental regulations and innovation, using data from UK manufacturing industry during 2000-2006. We estimate a dynamic model of innovation behaviour, and explicitly account for the likely endogeneity of our measure of the stringency of environmental regulations (pollution abatement costs). Our results indicate that while on the one hand environmental R&D and investment in environmental capital are stimulated by greater pollution abatement pressures, on the other hand there is not a positive impact of environmental regulation on total R&D or total capital accumulation. We find some evidence that this is because more stringent environmental regulations directly lower the optimal expenditure on non-environmental innovations. In addition, we find that environmental R&D may crowd out non-environmental R&D, although there is no evidence that environmental capital crowds out non-environmental capital.     

Green Innovation and Finance in Asia

Green innovation and green finance are two key components of sustainable development. In the most populous, fastest‐growing region in the world, Asian countries are pressed to maintain economic growth while addressing climate change and environmental externalities. Japan, South Korea, and China have each implemented policies to promote green innovation and finance conducive to such ends. While each country possesses unique capabilities, the extent to which they can promote environmentally adjusted multifactor productivity growth, green patent registrations, green bond issuances, green foreign direct investment, and environmental, social, and governance information disclosures stands to impact on their shifts to sustainable growth paradigms.     

Presidential Address: Mathematics in economics and econometrics

Abstract The paper discusses the choices of mathematical approaches in economics and econometrics, in particular, approaches that either (a) aim for a sharp result or (b) use the least restrictive assumptions. It is argued that, while the choice (a) often necessitates strong mathematical assumptions, choice (b) may lead to only partial identification and may require using less familiar mathematical techniques. This is discussed in the context of the problem of defining a probability density: existence may fail in function spaces; even after imposing assumptions that ensure existence, the problem is not well posed. A density function may not exist for economic variables as a consequence of institutional rigidity such as an income supplement. The apparatus of generalized functions provides the general solution to identification and well‐posedness of density, but at the cost of less sharp results and greater mathematical complexity.     

Presidential Address: Welfare Economics Beyond Welfarist-Consequentialism

Capitalizing on the recent work in social choice theory, I re-examine the foundations of post-Pigovian welfare economics and social choice theory. The structure of the "old" and "new" welfare economics is critically scrutinized, and the culprits of the poverty of welfare economics as well as of Arrovian social choice theory are boiled down to their common informational basis, referred to as welfarist-consequentialism . Alternative avenues that may be taken in an attempt to escape from the poverty of normative economics are identified and examined. These are focused on interpersonal comparisons of welfare levels, opportunity preferences and the procedural fairness of social choice.

The implications of heterogeneous resource intensities on technical change and growth

Abstract We analyze the long‐term dynamics of an economy in which sectors are heterogeneous with respect to the intensity of natural resource use. It is shown that heterogeneity induces technical change to be biased towards resource‐intensive sectors. Along the balanced growth path, the sectoral structure of the economy is constant as the higher resource dependency in resource‐intensive sectors is compensated by enhanced research activities. Resource taxes have no impact on dynamics except when the tax rate varies over time. Research subsidies and the sectoral provision of productivity‐enhancing public goods raise growth and provide an effective tool for structural policy.     

Marshallian Externalities in Innovation

A quality ladder model is used to test for Marshallian externalities in innovation. The model predicts that, in the absence of spillovers, the geographical distribution of research should be the same as that of production. This hypothesis is strongly rejected: innovation in two-digit industries exhibits strong spatial clustering independently of the distribution of employment. We find also, in support of Romer and Lucas, that there are strong spillovers from aggregate innovative activity in a region to the research intensity of individual industries. The location of a sector's R&D activity is determined more by the location of other sectors' innovation than by the location of its own production.     

Presidential Address: Antitrust restrictions on single-firm strategies

Abstract This article offers an overview of selected developments in the law and economics of antitrust regulation of single‐firm strategies. The strategy generating the most cases historically is resale price maintenance. Here, the law has moved sharply in both Canada and the U.S. towards more solid economic foundations. Yet a gap between the law and economics remains. The economics of resale price maintenance is reviewed within a framework that is much simpler and more general than the existing literature. The law on a second strategy, predatory pricing, represents in my view a success story for the influence of economic theory in spite of the absence of a single accepted theory of predatory pricing. The remaining single‐firm strategies are concerned largely with the exclusion by a dominant firm of rivals from a market. I review, with application to cases, the two most basic questions concerning exclusionary strategies. Are exclusionary, anticompetitive contracts ever entered into voluntarily by market participants? On the other hand, is complete or substantial foreclosure of a market through exclusionary strategies necessarily anticompetitive?     

Stimulating different types of eco-innovation in the UK: Government policies and firm motivations

In this paper, we adopt a recent OECD framework and examine the role of external policy tools and internal firm specific factors for stimulating three different types of eco-innovations that range on a spectrum of lower to higher technological and environmental impacts: End-of-Pipeline Pollution Control Technologies, Integrated Cleaner Production Technologies and Environmental R&D. Using a novel firm-level dataset from a DEFRA survey, we estimate a Tobit model, which provides empirical evidence showing that these eco-innovations are motivated by different external policy tools and internal firm specific factors. Our findings indicate that End of Pipeline Technologies and Integrated Cleaner Production Technologies are mainly driven by equipment upgrade motives with a view of improving efficiency while environmental regulations are effective in stimulating the End-of-Pipeline technologies and Environmental R&D. Interestingly, alongside government induced regulations, we find that market factors, mainly motivated by cost savings, are effective in driving Environmental R&D. Finally, ISO14001 certification is effective in strengthening the positive impact of environmental management systems on both End-of-Pipeline technologies and Environmental R&D while CSR policies have no significant impact on motivating any of the eco-innovations.

Innovation and Economic Growth in East Asia: An Overview

East Asia has been one of the most dynamic regions of economic growth and development. The past two decades have seen tremendous economic and technological catching up in the region. Using South Korea as a case to illustrate the process of technology catching up, we find that the process of graduating from imitation to innovation is a nonlinear one, and requires conscious efforts to invest in research and development and other technological capability‐enhancing activities. Successful technology upgrading also calls for policies and institutions that are relevant to technological innovation to evolve and adapt as an economy goes through the different stages of economic and technological development.     

Innovation and spillovers in regions: Evidence from European patent data

This paper estimates the effect of research externalities in generating innovation. We use R&D and patent data for European Regions in the 1977-1995 period. We find that spillovers are very localized and exist only within a distance of . The estimates are robust to simultaneity, omitted variable bias, different specifications of distance functions, country and border effects. However the size of these spillovers is small. Doubling R&D spending in a region would increase the output of new ideas in other regions within only by 2-3%, while it would increase the innovation of the region itself by 80-90%.     

Do resource dependent regions grow slower than they should?

A large literature documents a negative correlation between income growth and resource dependence. This correlation has been named the resource curse. We present evidence that suggests that the resource curse can be explained by a slow growing resource sector.     

Consumption risk, technology adoption and poverty traps: Evidence from Ethiopia

Much has been written on the determinants of technology adoption in agriculture, with issues such as input availability, knowledge and education, risk preferences, profitability, and credit constraints receiving much attention. This paper focuses on a factor that has been less well documented: the differential ability of households to take on risky production technologies for fear of the welfare consequences if shocks result in poor harvests. Building on an explicit model, this is explored in panel data from Ethiopia. Historical rainfall distributions are used to identify consumption risk. Controlling for unobserved household and time-varying village characteristics, it emerges that not just ex ante credit constraints, but also the possibly low consumption outcomes when harvests fail, discourage the application of fertilizer. The lack of insurance or alternative means of keeping consumption smooth leaves some trapped in low return, lower risk agriculture, one of the mechanisms through which poverty perpetuates itself in agrarian settings.     

Biodiversity conservation, loss of natural capital and interest rates

It is argued that there is neither regular relationship between changes in the level of the market rate of interest and variations in the rate of biodiversity loss nor does such a regular relationship occur between alterations in the market rate of interest and changes in the rate of natural resource extraction. However, some texts suggest otherwise. Microeconomic examples are given in which a rise in the market rate of interest results in increased biodiversity loss and others in which it does not. It is also posited that the rate of biodiversity loss (as well as the rate of natural resource extraction) tends to rise with the level of aggregate investment and aggregate economic activity. It is demonstrated, using macroeconomic models, that the market rate of interest can increase or decrease with a rise in aggregate investment and also with an increase in the level of aggregate economic activity. Therefore, changes in biodiversity loss (and in the rate of natural resource extraction) are independent of variations in the market rate of interest in macroeconomic models.     

The pollution terms of trade and its five components

Based on two extensions, this paper proposes a re-appraisal of the concept of the pollution terms of trade (PTT) introduced by Antweiler (1996). First, detailed data allows capturing the effect of differences in emission intensities across countries and over time. Second, relying on Johnson and Noguera (2012), the revised PTT index controls for trade in intermediate goods and is based on value-added rather than gross output figures. Applied to a database for SO₂ emission intensities for 62 developed and developing countries over the 1990–2000 period, it turns out that the first extension has a larger empirical importance than the second one. The global pattern is one in which the major rich economies exhibit a PTT index below one (higher pollution intensity in imports than in exports). Trade imbalances tend to exacerbate this asymmetry, allowing rich economies to further offshore their pollution through trade.
