ENVIRONMENTAL DYNAMICS AND THE LINKS BETWEEN GROWTH,VOLATILITY AND MORTALITY

I construct a model of a growing economy with pollution. The analysis of the model shows that the interactions between capital accumulation, endogenous lifetime and environmental quality determine both the long‐run growth rate and the pattern of convergence (i.e., monotonic or cyclical) towards the balanced growth path. I argue that such interactions can provide a possible explanatory factor behind the, empirically observed, negative correlation between growth and volatility. Furthermore, the model may capture the observed pattern whereby economic growth and mortality rates appear to be negatively related in the long run, but positively related in the short run.     

Quantifying the impact of economic crises on infant mortality in advanced economies

Policy makers rely on a mix of government spending and tax cuts to address the imbalances in the economy during an economic crisis, by promoting price stability and renewed economic growth. However, little discussion appears to focus explicitly on quantifying the cost of economic crises in terms of human lives, especially the lives of the most vulnerable members of society, infants. Using a statistical approach that is robust to the increases of mortality in outlying years, we quantify the effect that economic crises, periods of prolonged economic recession, have on infant mortality. Moreover, we investigate whether different levels of public spending on health across advanced industrialized democracies can mitigate the impact of crises on infant mortality. We find that economic crises are extremely costly and lead to a more than proportional increase in infant mortality in the short-run. Substantial public spending on health is required in order to limit their impact.

HEALTH IMPROVEMENTS AND THE TRANSITION OUT OF MALTHUSIAN STAGNATION

The central component of most economic models that analyse the transition from the Malthusian regime to self-sustaining developed economies is education. Improved health is normally envisaged as simply a by-product of economic growth. Whereas growth does, indeed, tend to improve health status, the reverse is also true, namely that health improvements are a dynamic force capable of driving economic expansion. This paper underlines the importance of health improvements in escaping from Malthusian stagnation. Further, and in contrast to existing literature, which emphasizes the effects of changes in mortality rates, this paper focuses on the relationship between health status and the efficiency of human capital technology. Through this channel, health improvements stimulate investments in child quality in terms of both nourishing and schooling and drive the economy towards the Modern Growth regime.

Cost Benefit Analysis of European Air Quality Targets for Sulphur Dioxide, Nitrogen Dioxide and Fine and Suspended Particulate Matter in Cities

The European Commission has proposed air quality standards for NO₂, SO₂ and PM₁₀ to be in force by 2010. The present paper presents a study that gauged their costs and benefits. An analysis of the expected emissions for 2010 (reference emission scenario), using simplified air quality models, showed that non-compliance with these standards will occur in cities only, not in rural areas. Most compliance problems are expected for PM₁₀, least for SO₂. Central estimates of the costs to meet standards range from 21 MECU (SO₂), to 79 MECU (NO₂) to 87--225 MECU (PM₁₀). The estimated benefits are 83--3783 MECU (SO₂), 408--5900 MECU (NO₂), and 5007--51247 MECU (PM₁₀). Uncertainties are high, due to errors and incertitude in various steps of the methodology, mainly the estimation of the human health effects, in particular effects on mortality, and in the valuation of a statistical life. In the case of PM₁₀, additional uncertainty results from the small size of the air quality database. Notwithstanding the uncertainties, the indications are that the benefits exceed the costs.     

Dynamics of environmental quality and economic development: the regional experience from Yangtze River Delta of China

This article investigates the dynamic relationship between economic progress and environmental quality at a regional level. An important economic intuition in this context is that environmental degradation will be limited by human behaviour if costs and benefits of such degradation are local since economic agents will then be incentivized to choose appropriate corrective action. Therefore, we note the likelihood that regional economic development can help regions ‘grow out of’ environmental problems. Using a new data set from Yangtze River Delta of China, we find a strong confirmation of the intuition that human can and will resolve the environmental problem by altering the damaging behaviour of economic agents. A very interesting finding of this study is that the relationship between environmental quality and economic progress measured by per capita income can display a wave-like function in the case of water pollution, as opposed to the much dramatized environmental Kuznets curve, with significant policy implications.

On Impatience, Economic Growth and the Environmental Kuznets Curve: A Dynamic Analysis of Resource Management

The paper presents a dynamic analysis of natural resource management and investigates some key factors that affect optimal management and resource conservation.Using a recursive specification of time preferences, we show how endogenous discounting and impatience can affect the motivation for both capital investments and environmental preservation. We examine the relationships between economic growth and environmental quality. Endogenous discounting provides new insights in the economic dynamics underlying the environmental Kuznets curve. By treating growth as endogenous, we examine how externalities and economic growth interact with each other. We investigate how economic development can contribute to an increased demand for environmental preservation. As an important new result, we also show how poverty can contribute to environmental degradation.     

INTEGRATED ENVIRONMENTAL AND ECONOMIC ACCOUNTING: FRAMEWORK FOR A SNA SATELLITE SYSTEM

National accounts have provided the most widely used indicators for the assessment of economic performance, trends of economic growth and of the economic counterpart of social welfare. However, two major drawbacks of national accounting have raised doubts about the usefulness of national accounts data for the measurement of long-term sustainable economic growth and socio-economic development. These drawbacks are the neglect of (a) scarcities of natural resources which threaten the sustained productivity of the economy and (b) the degradation of environmental quality from pollution and its effects on human health and welfare. In the present paper, the authors attempt to reflect environmental concerns in an accounting framework which maintains as far as possible SNA concepts and principles. To this end, the accounting framework is used to develop a "SNA Satellite System for Integrated Environmental and Economic Accounting" (SEEA). Environmental costs of economic activities, natural asset accounts and expenditures for environmental protection and enhancement, are presented in flow accounts and balance sheets in a consistent manner, i.e. maintaining the accounting identities of SNA. Such accounting permits the definition and compilation of modified indicators of income and expenditure, product, capital and value added, allowing for the depletion of natural resources, the degradation of environmental quality and social response to these effects. A desk study of a selected country is used to clarify the proposed approaches, to demonstrate their application in future country studies and to illustrate the quantitative effects of the use of modified concepts on the results of analysis.

Interrelationships between income,health and the environment: extending the Environmental Kuznets Curve hypothesis

This paper examines the link between the health indicators and the environmental variables for a cross-section of countries widely dispersed on the economic development spectrum. While environment and income are seen to have an inverted-U shaped relationship (Environmental Kuznets Curve (EKC) hypothesis), it is also well established that environment and health are positively related. Our study focuses on the implications of this for the relationship between health and income. In the early phases of income growth, the gains in health and the losses in environmental quality could cancel each other out and this challenges the idea that as incomes increase health would always improve. To empirically analyse these issues, we estimate a two-stage least squares model that focuses on the impact of income and the environment on health status, with environment being an endogenous variable. Our results show that the environmental stress variable has a significant negative effect on health status. At the same time, gross national product (GNP) levels are shown to vary positively with health status variables. We find that the health gains obtained through improved incomes can be negated to a significant extent if the indirect effect of income acting via the environment is ignored. Research findings in this regard would be a useful policy instrument towards maximising both the environmental and health gains that come with economic growth and development.     

Energy consumption,economic growth and environmental degradation in OECD countries

The interdependence among energy consumption, economic growth and environmental degradation has become an important public policy priority among OECD countries. Yet, the related literature provides conflicting results when describing the dynamic nature of such a relationship and the way it affects countries' development path. Using a sample of 35 OECD countries over the period 2000–2014, we find that economic growth and energy consumption patterns contribute to the enhancement of countries' environmental performance levels. In contrast to a large stream of empirical research, our findings highlight that countries' economic development path and their energy consumption patterns have started to align with their environmental policies. The results are robust since we utilize different aspects of countries' environmental degradation such as carbon dioxide emissions, ecological footprints and countries' environmental performance levels. Finally, the analysis of the dynamic interrelations among countries' energy consumption, economic growth and environmental degradation levels, reveals the necessity to promote sustainable development through a coexistence rather than through a trade-off mechanism.     

Health benefits of tunneling through the Chinese environmental Kuznets curve (EKC)

In this paper, we first add to what is a growing literature on the existence and nature of the environmental Kuznets curve (EKC) model for developing countries, by testing for the existence of an EKC for China using a panel data set of city-specific, annual ambient levels of SO₂ pollution. We find some support for both the typical inverted-U-shaped relationship and an N-shaped, cubic configuration. More significantly, we then explore the possibility of China's “tunneling” through the EKC, by using newer, cleaner technologies, and thereby avoiding some of the environmental degradation that had often accompanied economic growth. Specifically, we estimate and economically value the health benefits realizable to Chinese cities from successful efforts to “tunnel” under the EKC over the next generation.     

Does Improved Environmental Policy Enhance Economic Growth?

The environmental impacts on an economy is studied over time using endogenous growth theory. Externalities from the environment on production are central in the analysis, and we examine whether an optimal path realizes more rapid economic growth. The paper focuses mainly on developing countries, where production is largely influenced by the environmental quality. The result of the analysis indicates that the economic growth rate may not depend on the internalization of the environmental externality, but rather on the internalization of the human capital externality. The level of economic activity, however, generally seems to depend on the internalization of both externalities.     

Evolution of infant and child mortality in Chile: a model

The author contends that birth rate and infant and child mortality rates are jointly determined by demographic, economic, health care, and other influences. Working under this structural assumption, a multiequation model is developed, estimated, and simulated, in which real earnings, unemployment, midwife visits, access to cheap energy, public health expenditures, and degree of urbanization are determinant factors of declining infant and child mortality in Chile. Most notably, mortality declined during a period of increasing unemployment and falling living standards for at least part of the population. The study found all 3 rates to be jointly determined, but by different variables. Specifically, unemployment affected birth rate and child mortality rate, while declining infant mortality was based upon midwife visits, health expenditure, and access to cheap energy. At the policy level, trade-offs often result between infant and child mortality, especially where high birth rates prevail. Where movement along the Phillips curve is possible, higher earnings should be preferred over lower unemployment for the benefit of infant and child mortality. Preferred policy would week to provide a carefully balanced combination of better earnings and more midwife visits.

Biodiversity Loss and Economic Growth: A Cross-Country Analysis

This article empirically examines the relationship between biodiversity loss and economic growth in light of the current debate on the effects of economic growth on environmental quality. The basic premise is that biodiversity belongs to a special class of environmental degradation because it involves complex ecosystems, the loss of which cannot be recovered by technological advances. The main finding is that although economic growth has an expected adverse effect on biodiversity, the composition of economic output can also be significant, particularly in low-income countries. The study highlights the need to develop appropriate institutions and macroeconomic policies that allow biodiversity values to be internalized in decisionmaking processes.     

Channels of transmission of environmental policy to economic growth: A survey of the theory

Economists generally hold that environmental regulations impose constraints on the production possibilities set and are therefore potentially harmful to economic growth. In recent years, however, it has been recognized that environmental regulation can enhance the prospects for growth if improved environmental quality increases the productivity of inputs or the efficiency of the education system. It is also held that environmental regulation promotes pollution abatement activity and can lead to the exploitation of increasing returns to scale in abatement. Furthermore, expectations of a better environment may encourage households to save. Finally, it has been conjectured that environmental regulations can stimulate innovation because R&D is a relatively clean activity and because the market share of clean innovations increases. Future empirical research should shed light on the relative importance of these different channels of transmission of environmental policy to the growth rate of the economy.
