In the second edition of this user-friendly book, Olivier de La Grandville provides a clear and original introduction to the theory of economic growth, its mechanisms and its challenges. The book has been fully updated to incorporate several important new results and proofs since the first edition. In addition to a progressive treatment of dynamic optimization, readers will find intuitive derivations of all central equations of the calculus of variations and of optimal control theory. It offers a new solution to the fundamental question: How much should a nation save and invest? La Grandville shows that the optimal savings rule he suggests not only corresponds to the maximization of future welfare flows for society, but also maximizes the value of society's activity, as well as the total remuneration of labour. The rule offers a fresh alternative to dire current predictions about an ever-increasing capital-output ratio and a decrease of the labour share in national income.
In the 12th edition of Psychology and the Challenges of Life: Adjustment and Growth, authors Jeffrey Nevid and Spencer Rathus continue to reflect on the many ways in which psychology relates to the lives we live and the important roles that psychology can play in helping us adjust to the many challenges we face in our daily lives. Throughout this text, the authors explore applications of psychological concepts and principles in meeting life challenges such as managing our time, developing our self-identity, building and maintaining friendships and intimate relationships, adopting healthier behaviors and lifestyles, coping with stress, and dealing with emotional problems and psychological disorders. The text increases student's understanding by breaking down lengthy chapters into individualized study units designed to fit the busy lifestyles of today's students.
Economic growth and the environment is a complex and much debated issue. Per Kageson's book has a broader approach than earlier studies on this subject as he relates the analysis of present-day problems and trends (1960-2010) to clearly defined long-term objectives based on the concept of sustainable development. The present volume covers the use of non-renewable resources in the OECD countries in a global perspective, while the regional environmental impact of economic growth is discussed in a European context. The book also includes an analysis of the potential conflict between pollution abatement costs and economic growth.
