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.     

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.     

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.     

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.     

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.     

CO2 emissions, research and technology transfer in China

Although the economy of China has grown very strongly over the last few decades, this spectacular performance has come at the expense of rapid environmental deterioration. Amidst animated debate on the issue of global warming, this study attempts to explore the determinants of CO₂ emissions in China using aggregate data for more than half a century. Adopting an analytical framework that combines the environmental literature with modern endogenous growth theories, the results indicate that CO₂ emissions in China are negatively related to research intensity, technology transfer and the absorptive capacity of the economy to assimilate foreign technology. Our findings also indicate that more energy use, higher income and greater trade openness tend to cause more CO₂ emissions.     

Insurance,credit, and technology adoption: Field experimental evidencefrom Malawi

Does production risk suppress the demand for credit? We implemented a randomized field experiment to ask whether provision of insurance against a major source of production risk induces farmers to take out loans to adopt a new crop technology. The study sample was composed of roughly 800 maize and groundnut farmers in Malawi, where by far the dominant source of production risk is the level of rainfall. We randomly selected half of the farmers to be offered credit to purchase high-yielding hybrid maize and groundnut seeds for planting in the November 2006 crop season. The other half of farmers were offered a similar credit package, but were also required to purchase (at actuarially fair rates) a weather insurance policy that partially or fully forgave the loan in the event of poor rainfall. Surprisingly, take-up was lower by 13 percentage points among farmers offered insurance with the loan. Take-up was 33.0% for farmers who were offered the uninsured loan. There is suggestive evidence that reduced take-up of the insured loan was due to farmers already having implicit insurance from the limited liability clause in the loan contract: insured loan take-up was positively correlated with farmer education, income, and wealth, which may proxy for the individual's default costs. By contrast, take-up of the uninsured loan was uncorrelated with these farmer characteristics.     

Political foundations of the resource curse

In this paper we argue that the political incentives that resource endowments generate are the key to understanding whether or not they are a curse. We show: (1) politicians tend to over-extract natural resources relative to the efficient extraction path because they discount the future too much, and (2) resource booms improve the efficiency of the extraction path. However, (3) resource booms, by raising the value of being in power and by providing politicians with more resources which they can use to influence the outcome of elections, increase resource misallocation in the rest of the economy. (4) The overall impact of resource booms on the economy depends critically on institutions since these determine the extent to which political incentives map into policy outcomes. Countries with institutions that promote accountability and state competence will tend to benefit from resource booms since these institutions ameliorate the perverse political incentives that such booms create. Countries without such institutions however may suffer from a resource curse.     

Savings growth and the path of utility

Abstract.  We derive an expression relating the change in instantaneous utility to the growth of net (genuine) saving in an economy with multiple stocks and externalities that maximizes welfare in the utilitarian sense. This result is then shown to hold for decentralized competitive efficient economies as well, to yield an extension of the Hartwick rule: instantaneous utility is non-declining along a development path if genuine saving is decreasing. By way of example the rule is applied as a constant genuine saving rate rule in a simple Dasgupta-Heal-Solow-Stiglitz economy. The rule yields a path with unbounded consumption and higher wealth than on the standard Hartwick constant consumption path.     

Environment, human development and economic growth

Over the last few years, environmental issues have entered into policy design, particularly development and growth policies. Natural resources are considered necessary production inputs and environmental quality is considered a welfare determinant. The integration of environmental issues into economic growth and development theories and empirics is currently widely analyzed in the literature. The effects of natural resources endowment on economic growth are mainly analyzed through the so-called Resource Curse Hypothesis (RCH) whereas the effects of economic growth on environmental quality are part of the Environmental Kuznets Curve (EKC). Furthermore, recent contributions on RCH and EKC have shown the important role of institutions and human development dimensions in building a sustainable development path. In this paper, we attempt to analyze the causal relationships between economic growth, human development and sustainability combining the RCH and EKC models and adopting a human development perspective. Results confirm the importance of high institutional quality and investments for human capital accumulation in order to build a sustainable development path.     

Consumer support for environmental policies: An application to purchases of green cars

This paper focuses on how consumer motivation can be tapped in order to encourage the adoption of cleaner technologies. Consumers are heterogeneous — they may be guided by intrinsic motivation or extrinsic motivation. While information provision policies (such as the energy label for cars) may be effective in encouraging certain consumers to adopt green cars, financial incentive schemes (such as subsidies or fines) may be more persuasive for extrinsically-motivated consumers. We develop a dynamic theory of adoption of environmental innovations, in which information-provision policies are followed by financial incentives (first ‘carrot’, then ‘stick’ incentives). Analysis of a survey dataset of Swiss households observes considerable heterogeneity in terms of support of information-provision or financial incentive policies, in line with our conjectures. Our results will be of particular interest to policymakers interested in guiding consumers towards cleaner technologies.     

Efficiency and equity impacts of rural land rental restrictions: Evidence from India

Recognition of the potentially deleterious implications of inequality in opportunity originating in a skewed asset distribution has spawned considerable interest in land reforms. However, little attention has been devoted to the fact that, in the longer-term, the measures used to implement land reforms, especially rental restrictions, could negatively affect productivity. Use of state level data on rental restrictions, together with a nationally representative survey from India suggests that, contrary to original intentions, rental restrictions negatively affect productivity and equity by reducing scope for efficiency-enhancing rental transactions that benefit poor producers. Simulations suggest that, by doubling the number of producers with access to land through rental, from about 15 million currently, liberalization of rental markets could have far-reaching impacts.     

Economic Development, Trade and Wages

We present models that allow the use of unskilled and skilled labor as well as capital and land. Thus agriculture, important in developing countries, can be included as well as two types of labor and a single (or two) type(s) of physical capital. The models are related to the simple 3×2 specific factors structure by means of what is called the linear neighborhood structure, wherein no activity uses more than two factors, and the two types of labor work in separated sectors, using in common a type of physical capital. We discuss how wage rate changes are related when endowments change, when agriculture becomes traded and prices rise, and when unskilled labor becomes educated and joins the ranks of skilled workers.     

A model of technological breakthrough in the renewable energy sector

Models with induced technological change in the energy sector often predict a gradual expansion of renewable energies, and a substantial share of fossil fuels remaining in the energy mix through the end of our century. However, there are historical examples where new products or technologies expanded rapidly and achieved a high output in a relatively short period of time. This paper explores the possibility of a ‘technological breakthrough’ in the renewable energy sector, using a partial equilibrium model of energy generation with endogenous R&D. Our results indicate, that due to increasing returns-to-scale, a multiplicity of equilibria can arise. In the model, two stable states can coexist, one characterized by a lower and one by higher supply of renewable energy. The transition from the low-output to the high-output equilibrium is characterized by a discontinuous rise in R&D activity and capacity investments in the renewable energy sector. The transition can be triggered by a rise in world energy demand, by a drop in the supply of fossil fuels, or by policy intervention. Under market conditions, the transition occurs later than in the social optimum. Hence, we identify a market failure related to path-dependence and technological lock-in, that can justify a strong policy intervention initially. Paradoxically, well-intended energy-saving policies can actually lead to higher emissions, as they reduce the incentives to invest in renewable energies by having a cushioning effect on the energy price. Hence, these policies should be supplemented by other instruments that restore the incentives to invest in renewable energies. Finally, we discuss the influence of monopoly power in the market for innovations. We show that market power can alleviate the problem of technological lock-in, but creates a new market failure that reduces static efficiency.     

The environmental Kuznets curve when the environment exhibits hysteresis

The relevance and implications of the environmental Kuznets hypothesis are examined in the presence of stock effects and non-linearities associated with pollution generation. Stock effects lead to hysteresis and irreversibilities in environmental quality that are overlooked when emphasis is placed on the flow effects of pollutants only. It is demonstrated here that an optimal growth plan in the presence of stock effects shifts the focus away from prescribing economic growth as a panacea for environmental ills. Implications for currently industrializing economies are discussed.
