Environmental Kuznets Curves - one of the most controversial issues of current environmental economics - suggest that economic growth may lead to environmental quality improvements. Why and under which circumstances this may be so, are the questions addressed in this book. The approach taken is formal, using techniques of static and dynamic optimisation. In addition, the main assumptions, arguments and conclusions are also presented in a non-formel way.

After decades of solid growth, the worldwide ocean cruise sector has become a noticeable economic factor and a significant employer. In the way it combines social, technological and natural systems to form its products, cruise tourism is an increasingly attractive area of study particularly with regards to the managerial challenges posed by the interaction of these systems. This book brings together industry know-how, managerial experience and academic rigor to cover some of the most important and interesting managerial challenges associated with ocean cruises.
