Economists have come to believe that using resources efficiently can lead to differences in the growth rates of economies. Efficient use of resources is known to improve the standard of living of the people thereby increasing their welfare. However, initially ‘capital’ and later on ‘labour’ attracted the attention of the economists. The need for the efficient use of resources was only recognized as an important determinant in the growth of economies in the fifties. Economists believe that the developing countries in particular need to concentrate on improving the efficiency of their use of resources, since these economies have an increasing number of people to feed and proportionally little resources at their disposal. Whenever there is talk of efficiency regarding the use of resources it means that all the resources that are used in the process of production should be used efficiently. These resources are: capital, labour, raw materials, power, fuel and the skills of the entrepreneur. Efficiency is reflected in the unit or average cost of production and in the quality of goods. Before the introduction of the reforms, the Indian industrial sector was characterized by numerous controls, which restricted internal as well as external competition. However, after the reforms such controls were loosened and it is now simply expected that the Indian industrial sector uses its resources efficiently. The present study examines whether there have been significant reductions in the components of the average variable cost in the post-reform period as compared to the pre-reform period. Furthermore, it analyses whether there has been any noticeable increase in advertising expenditure of the firms in the post-reform period.

This book highlights methodological approaches for the economics of sustainable development and brings together recent empirical work done in India, especially by Dr. Surender Kumar and Dr. Shunsuke Managi. Various chapters in this book use Indian data to show the very wide applicability of methodologies in the theory of production for dealing with many empirical issues of environmentally sustainable development in a developing country. I congratulate the authors for the time and effort devoted to compiling this very useful reference on the subject and the publishers for publishing this volume. The methodologies of cost functions, distance functions, and production fu- tions have been used in many recent studies and in the studies reported in this book for environmental valuation. Environmental valuation is required for designing policy instruments like pollution taxes for sustainable development and for meas- ing green GDP. The UN methodology of integrated environmental and economic accounting provides ways of measuring the cost of maintaining environmental resources at sustainable levels or the maintenance cost for estimating green GDP. Some of the chapters in this book show that the methodology of distance functions could be used for estimating the cost of environmentally sustainable development.

This volume comprehensively captures trends in productivity and its determinants in the post-reform period for Indian manufacturing. It provides an up-to-date survey of different methods employed in measuring productivity and their applications across organized and unorganized sectors, including food, beverages, furniture, gems, chemicals, petroleum and rubber, metals and minerals, paper products, publishing, textiles, etc. The essays examine the uneven impact of economic reforms and growth on the performance of the manufacturing sector. This will be especially useful to students and scholars of economics, business and management, policymakers and governmental agencies, particularly those interested in Indian economy and manufacturing.

1.1 Production: Cost of production is the deciding factor for supply which depends upon prices of raw materials and its physical relation between input and output. It is the physical relation between input and output which determines the cost of production. Production represents functional relationship between quantities of inputs and amount of output produced. Production is an economic activity. Production is used for an activity of making some material. In economics, production is used in a wider sense. 1.2 Importance of Production: Price theory plays an important role in the theory of production. This provides a base for analysis of relationship between costs and amounts of output. Cost along with demand and supply of a product determine the price of a product. Cost of production is determined by the prices of inputs of production and thereby the price of product. Secondly, the basis of theory of firm demand for factors of production is theory of production. The theory of production plays a pivotal role in theory of firm. The theory of firm deals with the level of output whichwill produce in turn the maximum profits. The firm’s marginal and average costs of production decide the profits maximizing output besides the demand conditions. In addition to the prices of inputs, the changes in marginal and average costs of production as a result of increase in output are determined by the physical relationship between inputs and output.

Impact of liberalization on informality has been a subject of intense debate for many years and the major issue that has come up is whether liberalization helps to grow informal sector and informality in the economy or it is an obstruction for informal sector’s growth. Thus, in the light of the recent liberalization measure, this book sets to examine general presumptions of the development of informal sector in the context of the Indian economy. The book begins with a broad framework for analysis of output contribution and growth of the informal sector. Liberalization is measured by openness indices and inter-sectoral linkages. Impact of liberalization on growth contributions of informal sector is captured by openness indices (i.e. degree of openness to trade and principal component scores), technical efficiency (measured by Data Envelope Analysis and estimated by Tobit Censored Regression model) and components of productivity (computed by Malmquist total factor productivity index) of the informal enterprises by inter-sectoral linkages. The linkages are modeled theoretically in a neo-classical growth theory and empirically measured by sub-contracting arrangements between formal and informal enterprises. In addition, the book also provides implications on promotion of informal sector from the viewpoint of employment generation. The description and analyses of the book will help with policy implications and enlighten the readers on the development of informal sector.

Environmental Sustainability, Growth Trajectory and Gender focuses on three major issues affecting developing economies: environmental sustainability, growth trajectory and gender. Awareness is increased through an exploration of policies and actions that will enhance gender equality and sustainable development.

The book pays tribute to the celebrated economist Professor Suresh Tendulkar’s contribution and scholarship to economics, economic-policy making, and economic reforms in India. Professor Tendulkar served on numerous panels and commissions set up to reform diverse aspects of India’s economy. To name a few, he served as the Chairperson of the Prime Minister’s Economic Advisory Council, Chairman of the National Commission of Statistics, National Sample Survey Organisation, Committee on National Accounts, and as a member in the Fifth Pay Commission, the Disinvestment Commission (1996). He is credited with devising the new method to estimate poverty in India which resulted in India’s poverty estimates being scaled up. This book primarily focuses on Professor Tendulkar’s contributions on economic planning in India, the political economy of economic reforms, and his important conceptual and policy-relevant work on poverty measurement. The three sub-themes of the book – Economic Reforms and Policy Formulation, Poverty and Inequality, and Development and Trade – are indicative of his specific research interests, namely poverty and well-being, and India and the world economy. It covers both micro and macro aspects relevant to the Indian economy. The econometric techniques utilized encompass state-of-the-art microeconometric as well as macroeconometric models. The book contains contributions from eminent economists associated with Professor Tendulkar, and is useful for readers from the undergraduate through the Ph.D. level as well as researchers and practitioners of economics.
