Abstract

We augment an AK model by treating the units of time devoted to work as a choice variable and by introducing an environmental resource entering the households" utility function. In general, the resulting model does not generate endogenous growth in the absence of negative externalities: perpetual growth can be generated only when the resource deteriorates because of the consumer activities. In this case, indeed, the households keep their labor supply and saving rates relatively high in spite of their increasing private wealth in order to consume more private goods as substitutes for the declining quality of the environment.

National and international economic policy has usually ignored the environment. In areas where the environment is beginning to impinge on policy, as in the General Agreement on Tariffs and Trade (GATT) and the North American Free Trade Agreement (NAFTA), it remains a tangential concern, and the presumption is often made that economic growth and economic liberalization (including the liberalization of international trade) are, in some sense, good for the environment. This notion has meant that economy-wide policy reforms designed to promote growth and liberalization have been encouraged with little regard to their environmental consequences, presumably on the assumption that these consequences would either take care of themselves or could be dealt with separately. In this article, we discuss the relation between economic growth and environmental quality, and the link between economic activity and the carrying capacity and resilience of the environment.

Recent empirical research indicates that certain types of emissions follow an inverted-U or environmental Kuznets curve (EKC) as income grows. This regularity has been interpreted as a possible de-linking of economic growth and patterns of certain pollutants for developed economies. In this paper the empirical basis of this result is investigated by considering some statistical particularities of the various EKC studies performed. It is argued that the inverted-U relationship between income and emissions estimated from panel data need not hold for specific individual countries over time. Based on insights from `intensity-of-use' analysis in resource economics, an alternative growth model is specified and estimated for three types of emissions (CO2, NOx and SO2) in four countries (Netherlands, UK, USA and Western Germany). It is found that the time patterns of these emissions correlate positively with economic growth and that emission reductions may have been achieved as a result of structural and technological changes in the economy. `Sustainable growth' is defined as the rate of economic growth that does not lead to growth in emissions. Its rate is calculated for each type of emission and country, based on estimated parameter values. The resulting indicators reflect a balance between the positive influence of growth and negative influence of structural change and technological progress on emission levels.

The wide cross-country disparity in rates of economic growth is the most puzzling feature of the development process. This paper describes a class of models in which this heterogeneity in growth experiences can be the result of cross-country differences in government policy. These differences can also create incentives for labor migration from slow-growing to fast-growing countries. In the models considered, growth is endogenous despite the absence of increasing returns because there is a “core” of capital goods that can be produced without the direct or indirect contribution of factors that cannot be accumulated, such as land.

A Beckerian model of household production is developed to study the cyclical allocation of capital and time between market and home activities. The adopted framework treats the business and household sectors symmetrically. In the market, labor interacts with business capital to produce market goods and services, and likewise at home the remaining time (leisure) is combined with household capital to produce home goods and services. The model presented is parameterized and simulated to see whether it can rationalize the observed allocation of capital and time, as well as other stylized facts, for the postwar U.S. economy.

This paper explores some macroeconomic implications of including household production in an otherwise standard real business cycle model. The authors calibrate the model on the basis of microeconomic evidence and long-run considerations, simulate it, and examine its statistical properties. They find that introducing home production significantly improves the quantitative performance of the standard model along several dimensions. It also implies a very different interpretation of the nature of aggregate fluctuations. Copyright 1991 by University of Chicago Press.

Those who say that money can't buy happiness don't know where to shop. Anon. Do you think your children's lives will be better than your own? Probably not; nobody does these days… In all countries there is doom and gloom, a universal sense of decay. Norman Stone, historian. What we call happiness in the strictest sense of the word comes from the (preferably sudden) satisfaction of needs which have been dammed up to a high degree. Sigmund Freud, psychologist. Happiness is the sublime moment when you get out of your corsets at night. Joyce Grenfell, actress. Economic performance is not intrinsically interesting. No‐one is concerned in a genuine sense about the level of gross national product last year or about next year's exchange rate. People have no innate interest in the money supply, inflation, growth, inequality, unemployment, and the rest. The stolid greyness of the business pages of our newspapers seems to mirror the fact that economic numbers matter only indirectly.

tainability is based on the balance between the ever-changing types and quantities of environmental life support used by society, and the long-run ability of natural ecosystems to provide life support. This bal-ance can be evaluated by criteria that combine the strengths of social indicators, which measure the economic and technical factors that determine the use of life support, and natural science indicators, which model the long-run ecological effects of using life support.
Article
We examine the reduced-form relationship between per capita income and various environmental indicators. Our study covers four types of indicators: urban air pollution, the state of the oxygen regime in river basins, fecal contamination of river basins, and contamination of river basins by heavy metals. We find no evidence that environmental quality deteriorates steadily with economic growth. Rather, for most indicators, economic growth brings an initial phase of deterioration followed by a subsequent phase of improvement. The turning points for the different pollutants vary, but in most cases they come before a country reaches a per capita income of $8000.

Advanced economies have experienced a tremendous increase in material well-being since the industrial revolution. Modern innovations such as personal computers, laser surgery, jet airplanes, and satellite communication have made us rich and transformed the way we live and work. But technological change has also brought with it a variety of social problems. It has been blamed at various times for increasing wage and income inequality, unemployment, obsolescence of physical and human capital, environmental deterioration, and prolonged recessions. To understand the contradictory effects of technological change on the economy, one must delve into structural details of the innovation process to analyze how laws, institutions, customs, and regulations affect peoples' incentive and ability to create new knowledge and profit from it. To show how this can be done, Philippe Aghion and Peter Howitt make use of Schumpeter's concept of creative destruction, the competitive process whereby entrepreneurs constantly seek new ideas that will render their rivals' ideas obsolete. Whereas other books on endogenous growth stress a particular aspect, such as trade or convergence, this book provides a comprehensive survey of the theoretical and empirical debates raised by modern growth theory. It develops a powerful engine of analysis that sheds light not only on economic growth per se, but on the many other phenomena that interact with growth, such as inequality, unemployment, capital accumulation, education, competition, natural resources, international trade, economic cycles, and public policy.
Book
In this book, Jon Conrad and Colin Clark develop the theory of resource economics. To begin, they provide an introduction to the required techniques of dynamic optimization. Throughout the book they build the reader’s understanding with many fully-worked problems and numerical examples. The authors have written this text in the belief that the theory and concepts of resource are more quickly learned, more effectively made operational, and more truly understood if the reader is exposed to carefully explained numerical examples. By working through the problems at the end of each chapter, students will learn the techniques to be used in empirical studies of natural resource systems. The first chapter provides an introduction to optimization, including constrained optimization, dynamic allocation problems, dynamic programming, continuous time problems, and the maximum principle, and a discussion of various numerical and graphical techniques. The remaining chapters deal in depth with the economics of renewable resources, nonrenewable resources, with environmental management and with stochastic resource models.

First published in 1973, this is a radical interpretation, offering a unified explanation for the growth of Western Europe between 900 A. D. and 1700, providing a general theoretical framework for institutional change geared to the general reader.
Article
This paper considers the prospects for constructing a neoclassical theory of growth and international trade that is consistent with some of the main features of economic development. Three models are considered and compared to evidence: a model emphasizing physical capital accumulation and technological change, a model emphasizing human capital accumulation through schooling, and a model emphasizing specialized human capital accumulation through learning-by-doing.

The nonrivalry of technology, as modelled in the endogenous growth literature, implies that high population spurs technological change. This paper constructs and empirically tests a model of long-run world population growth combining this implication with the Malthusian assumption that technology limits population. The model predicts that over most of history, the growth rate of population will be proportional to its level. Empirical tests support this prediction and show that historically, among societies with no possibility for technological contact, those with larger initial populations have had faster technological change and population growth. -Author

This paper analyses the equilibrium dynamics of an endogenous growth model with physical and human capital in which leisure enters the utility function. The inclusion of leisure introduces a potential source of non-convexities in our optimization problem and leads to the possible existence of multiple balanced growth paths. This multiplicity of optimal stationary solutions is linked to the assumption that education has no effect on the quality of leisure, and hence a relatively more educated economy may choose to grow faster, and devote more time to income-directed activities. To characterize the set of optimal solutions in our non-concave optimization framework we develop a new method of analysis that should be of interest in related applications.
Article
The authors argue that many goods and decisions are not allocated or made through markets. They interpret an agent's status as a ranking device that determines how well he or she fares in the nonmarket sector. The existence of a nonmarket sector can endogenously generate a concern for relative position in, for example, the income distribution so that higher income implies higher status. Moreover, it can naturally yield multiple equilibria. It is thus possible to explain differences in growth rates across countries without recourse to differences in underlying preferences, technologies, or endowments. Different social organizations lead to different reduced-form preferences, which lead to different growth rates. Copyright 1992 by University of Chicago Press.
Article
A new measure of 'voraciousness' in leisure activities is introduced as an indicator of the pace of leisure, facili-tating a theoretical linkage between the literature on time pressure, busyness and harriedness in late modernity, and the literature on cultural consumption. On the methodological side it is shown that time use diaries can pro-vide at least as good a measure of the pace of leisure as survey based measures. Respondents with a high score on the voraciousness measure ('harried' respondents) are not less likely to complete their diaries than less harried respondents. In accord with the findings from the literature on cultural omnivorousness, the most voracious groups are those with high levels of social status and human capital. However, these associations are not due to these groups having either higher income or greater quantities of available leisure time. The pace of leisure ac-tivities must therefore be due to other factors, for example, could a fast pace of out-of-home leisure participation be conceived of as a new marker of status distinction?

The main goal in this paper is to analyze an economic model of endogenous growth where human capital accumulation acts as the engine propelling economic activity. The added ingredient in our model is that agents derive utility from consumption and leisure, where leisure is defined as the amount of time devoted to those activities augmented by the level of education. Under regular conditions we show that there is a unique globally stable balanced growth path. We also provide a characterization of the behavior of our economic variables along the transition.

Traditional growth theory emphasizes the incentives for capital accumulation rather than technological progress. Innovation is treated as an exogenous process or a by-product of investment in machinery and equipment. Grossman and Helpman develop a unique approach in which innovation is viewed as a deliberate outgrowth of investments in industrial research by forward-looking, profit-seeking agents.

Endogenous growth is generally built on a positive externality hypothesis which is the opposite of a negative externality caused by pollution. We study a linear technology with simple assumption: an aggregate capital stock which represents a learning by doing effect and a pollution flow proportional to production. In this framework, we analyse the precise effects on growth of the disutility of pollution and its interaction with the utility of consumption in an economy without abatement technology. The decentralized equilibrium always leads to unlimited growth, but optimal growth is often limited (the negative effect of pollution dominating the positive effect of learning by doing). In this case, the optimal policy which leads the decentralized economy to follow the optimal growth path is to tax capital; in contrast with the optimal subsidy policy in an economy without pollution. When an abatement technology is introduced, the optimal solution can lead the economy to unlimited growth, whatever the form of the utility function. Copyright Kluwer Academic Publishers 1995

A simple theoretical model of pollution is developed that generates an inverted U-shape relationship between per capita income and environmental quality. This model is then used to study long-run growth. The same inverted U-shape is shown to appear in time series and the prospects for sustained growth are shown to hinge on whether increasingly strict environmental regulation is compatible with a constant rate of return on capital. Implementation is also studied. Tax and voucher schemes are shown to have an advantage over direct regulation because they provide the correct incentives for capital accumulation.

If individuals are interested in their relative wealth position, they engage in contests for wealth. This leads to a steady state with overaccumulation. In a simple growth model it is shown that, if some individuals are engaged in wealth seeking activity, but others are not, the latter might benefit. However, wealth seeking is not welfare enhancing under usual assumptions concerning production technology. The steady-state equilibrium is characterized by a marginal productivity of capital that is below the steady-state rate of time preference and by emergence of a class structure.
Article
A model of endogenous growth is developed in which growth is driven by vertical innovations that involve creative destruction. Equilibrium is determined by a forward-looking difference equation, according to which the amount of research in any period depends negatively upon the amount expected next period. The paper analyzes positive and normative properties of stationary equilibria, and shows conditions for the existence of cyclical equilibria and no-growth traps. The growth rate may be more or less than optimal because a business-stealing effect counteracts the usual spillover and appropriability effects. In addition, innovations tend to be too small.
