This book addresses nine relevant questions: Will population growth reduce the growth rate of per capita income because it reduces the per capita availability of exhaustible resources? How about for renewable resources? Will population growth aggravate degradation of the natural environment? Does more rapid growth reduce worker output and consumption? Do rapid growth and greater density lead to productivity gains through scale economies and thereby raise per capita income? Will rapid population growth reduce per capita levels of education and health? Will it increase inequality of income distribution? Is it an important source of labor problems and city population absorption? And, finally, do the economic effects of population growth justify government programs to reduce fertility that go beyond the provision of family planning services?
This thesis covers a broad range of topics in the general area of economic growth theory and economics of technological change. It is primarily about the ultimate sources of growth and its ultimate limitations. We scrutinize the implications of several specifications of long-run growth “engines” found in the theoretical literature and put forward their generalizations and extensions. At the highest level of generality, we provide a formal proof that balanced (i.e. exponential) growth requires knife-edge assumptions which cannot be satisfied by typical values of model parameters. This result implies that at least one such knife-edge assumption must be made if a given model is supposed to deliver balanced growth over the long run. Next, we deal with the issue of resource-based limits to long-run growth. We propose to promote technological progress which would improve the substitutability between non-renewable and renewable resources: if the elasticity of substitution between the two kinds of resources exceeds unity, production will not fall down to zero even after the non-renewable resources will have been completely depleted. Another question asked is whether it is plausible that R&D-based growth, fueled by steady increases in the world’s population, can be extended into indefinite time. We answer this question by introducing endogenous fertility choice, with population entering the utility functional multiplicatively, into an R&D-based semi-endogenous growth model. The next issue addressed here are the idea-based microfoundations of aggregate production functions. We discuss the correspondence between the shape of production functions, the direction of technical change, and the possibility of sustained endogenous growth. A broad class of production functions, nesting both the Cobb-Douglas and the CES function, is derived. Finally, we discuss the impact of the heterogeneity of innovations on long-run economic dynamics: we augment the semi-endogenous growth model with a distinction between radical and incremental innovations. Total R&D output is assumed to depend on technological opportunity which is depleted by incremental innovations but renewed by radical innovations. The dynamic interplay of the arrivals of the two types of innovations is shown to give rise to transitional oscillations.
As improving energy efficiency and increasing energy R&D investment may be the main means for China's industrial sector to achieve sustainable growth, this book attempts to unify energy use efficiency and energy R&D inputs into a standardized economic analysis framework. By distinguishing between energy R&D inputs and non-energy R&D inputs, this book draws on the research paradigm of neoclassical economics to clarify the basic concepts and endogenous mechanisms of energy-saving technological progress as a logical starting point. Under the framework of the existing endogenous growth theory analysis, the heterogeneous R&D inputs are divided into two different mechanisms that affect energy use efficiency, namely factor substitution effect and energy-efficient input increase effect, and a heterogeneous R&D input is constructed. This book constructed an analytical framework for endogenous energy-saving technological progress in the industrial sector based on heterogeneous R&D inputs; it established a mathematical model for the endogenous energy-saving technological advancement of the industrial sector based on heterogeneous R&D inputs; it estimated the energy-saving technological progress rate of 37 Chinese industrial sub-sectors from 1980 to 2010; fourth, it has empirically examined the relationship between the heterogeneous R&D investment in China's industrial sector and its energy-saving technological advancement rate.
Technological change is today central to the theory of economic growth. It is recognised as an important driver of productivity growth and the emergence of new products from which consumers derive welfare. It depends not only on the work of scientists and engineers, but also on a wider range of economic and societal factors, including institutions such as intellectual property rights and corporate governance, the operation of markets, a range of governmental policies (science and technology policy, innovation policy, macroeconomic policy,competition policy, etc.), historical specificities, etc. Given that technology is explicitly taken up in the strategies and policies of governments and firms, and new actors both in the national and international arenas become involved, understanding the nature and dynamics of technology is on demand. I anticipate that this book will decisively contribute in this regard.
This textbook covers the full range of topics and issues normally included in a course on economic growth and development. Both mainstream economic perspectives as well as the multi-paradigmatic, inter-disciplinary, and dynamic-evolutionary perspectives from heterodox economics are detailed. Economic development is viewed in terms of the long-run well-being of humanity, social stability, environmental sustainability, and just distribution of economic gains, not simply as the growth of GDP. Furthermore, this textbook explicitly recognizes the complexity of economic development by linking economic activity to our broader social and natural environments.The textbook's unique feature is its focus on the natural environment. Both the historical effects of economic development on the environment and the environmental constraints on future economic development are thoroughly discussed in two chapters on environmental issues and policies. In fact, because economic development is defined in terms of economic, social, and environmental sustainability, the natural environment is included in discussions throughout the book.The textbook is inter-disciplinary: knowledge from fields such as sociology, psychology, political science, economic history, and ecology is called on to enhance the economic analysis. A thorough historical account of the development of the principal paradigms of economic development is also included, and the important issues of institutional development and cultural change merit their own chapters. Two chapters on technological change holistically focus on production technologies as well as the dynamic performance of entire economic, social, and ecological systems. Also, the important relationship between economic development and globalization is presented in three chapters on international trade, international finance and investment, and immigration from both orthodox and heterodox perspectives.

The chapters in the book cover a broad range of aspects regarding the relationship between natural resource use and long-term economic development. The book surveys existing literature as well as adds to frontier research. In particular, the following topics are studied: incentives for adoption and diffusion of clean technology, resource scarcity and limits to growth, international convergence of energy intensity, and the social norms shaping resource depletion.
Economic Growth and the Environment explores the debate on how to reconcile economic growth with protection of the natural environment, and the closely related discussion on whether an increasing scarcity of natural resources will eventually force economic growth to cease. The debate focusses on whether environmental policies will benefit the economy or not, and is divided into growth optimists and growth pessimists. In general, economists have been optimistic and have pointed to the possibilities of technological progress and substitution, yet they also acknowledge that natural resources and environmental concern do restrict economic growth. The difficulty lies in quantifying the constraint to economic growth. Modern growth economists have constructed models to examine to what extent 'growth pessimism' is theoretically warranted. This book provides an introduction to some of these models, brings together the discussion between growth optimists and pessimists, and presents the theory behind their arguments. It aims to present models where both sides can meet and where both are able to derive expected results with the parameter values that they deem appropriate. From there, the discussions can turn to the empirical observations about these parameters. This book will be of interest to advanced undergraduates in economics, microeconomics, economic growth, sustainable development, and environmental economics. Each chapter concludes with a set of Exercises designed to help the reader master the models.
In this volume, a group of distinguished international scholars provides a fresh investigation of the most fundamental issues involved in our dependence on natural resources. In Scarcity and Growth (RFF, 1963) and Scarcity and Growth Reconsidered (RFF, 1979), researchers considered the long-term implications of resource scarcity for economic growth and human well-being. Scarcity and Growth Revisited examines these implications with 25 years of new learning and experience. It finds that concerns about resource scarcity have changed in essential ways. In contrast with the earlier preoccupation with the adequacy of fuel, mineral, and agricultural resources and the efficiency by which they are allocated, the greatest concern today is about the Earth‘s limited capacity to handle the environmental consequences of resource extraction and use. Opinion among scholars is divided on the ability of technological innovation to ameliorate this 'new scarcity.' However, even the book‘s more optimistic authors agree that the problems will not be successfully overcome without significant advances in the legal, financial, and other social institutions that protect the environment and support technical innovation. Scarcity and Growth Revisited incorporates expert perspectives from the physical and life sciences, as well as economics. It includes issues confronting the developing world as well as industrialized societies. The book begins with a review of the debate about scarcity and economic growth and a review of current assessments of natural resource availability and consumption. The twelve chapters that follow provide an accessible, lively, and authoritative update to an enduring-but changing-debate.
