The book Quantitative Techniques is basically a treatise written to train the readers to use the techniques of mathematical and statistical analysis, which are commonly applied to understand and analyse economic problems. The thrust is on understanding the economic concepts with the help of mathematical methods rather than learning mathematics itself. The subject matter of the book is specially designed for use by students/teachers, who have got a rudimentary knowledge of mathematics and as such it is presumed that the readers are aware of only with elementary algebra and geometry. This book also deals with simple tools and techniques, which may help readers in the collection, compilation, presentation, analysis of data and drawing inferences about statistical hypotheses. The book contains six modules (Three of mathematical methods and three of statistical methods) which run in Twenty One chapters. Various mathematical concept like Functions, Limits and Continuity, differential and Integral Calculus, Input-output analysis, Game Theory, linear programming, etc. are dealt with the help of illustrations from economics. Similarly, various statistical tools like Correlation and Regression analysis, Estimation and Testing, Probability, Census and Sample investigations, etc., are also dealt in separate chapters in last three modules. The book is supposed to fulfill the object in all its perfection, but no one can claim for complete perfection, so is the case with this book also.

The distinctive features of the present book are-one, besides serving as textbook for B.A./B.Sc./B.Com. (Pass & Hons.), M.A. (Econ.)/M.Com./ M.Sc. (Maths & Stat.) of Indian and Nepalese Universities; C.A.; I.C.W.A.; M.B.A.; it also covers the syllabi of different competitive services like I.A.S./I.E.S./I.S.S./P.C.S. etc. Two, it is a treatise on the statistical methodology discussing theoretical, practical and applied aspects in clear and lucid manner to serve in better way to students, teachers, administrators and general readers. The contents of the book have been organized in five parts. In part I, introduction, meaning and scope of statistics is discussed widely. Part II deals with Statistical Research Methodology, enveloping problems of investigations, viz., collection, tabulation, editing, presentation of data. Part III, the Statistical Paradigms-The Descriptive Statistics studies Central Tendencies, Dispersions, Moments, Skewness and Kurtosis; Index Numbers; Time Series, Correlation; Regression; Interpolation; Association of Attributes; Probability and Mathematical Expectation; Theoretical Frequency Distribution, exhaustively. Part IV: Theory of Estimation and Hypothesis-Testing the Inductive Statistics deals with different tests like Students t-distribution; F-test; Z-transformation; Chi-Squared; Analysis of Variance; S.O.C.; Business Forecasting; Design of Experiments; and Interpretation of Data. In Part V: Indian Statistics-attempts have been made to apprise the readers with different statistical systems of India and its States, and different official statistics like Population, Agriculture, Industry, Labour, Price, Trade, etc.

The book in hand intends to provide the readers as well as graduate/post-graduate students of economics, environmental economics some insights into the application of economic theory in designing and implementing the public policies related to the management of the environment and social sectors. This finds roots in welfare economics, national income accounting, macro-economic policies, trade and development. The subject matter of the book, which is related to the issues of environmental economics, environmental and social services and their valuation, and designing of instruments and institutions for the management of environment, the models of optimal use of natural resources, macroeconomic issues, sustainable development; environmental resource problems in India, the economics of health and education, is widely discussed in eighteen chapters incorporated in seven modules. Environmental demand theory (covering both revealed preference and stated preference): Household production model, contingent valuation method; Pigouvian fees; Coase's theorem of property rights; Monitoring and enforcement of regulation and related acts, etc. are various captions which may draw special attention of the readers. In this way the book fills a particular niche in the market for post-graduate texts.

The small-scale sector is an effective instrument of social change and economic growth in a number of countries.

In modern India the Small-scale Industries have been a success story. The have emerged vibrantly in the face of rising threats from large-scale sectors inside the country and multinationals from abroad. At the micro-level the small-scale sector has succeeded in diffusing entrepreneurship culture and played a prominent role in converting the physical, material and human resources into productive assets. The post-liberalization business environment has turned harsh for the small scale sector due to increased internal and external competition. The far reaching impact of various WTO norms has also posed a threat to the future of small scale sector in India. This book, presented in four sections, contains articles written by different scholars and experts in their respective fields. Section-I deals with an overview of the SSI policy perspectives during the era of planning and the growth of the sector. Section-II presents a brief account of WTO and Small industry development in India. Section-III analyses the genesis, scope and role of District Industries Centres (DICs) and various issues confronting them. Section-IV provides an insight into the role of Government institutions in the development of infrastructure to motivate and encourage small entrepreneurs with special reference to Andhra Pradesh.
