This book analyses the growth, development and crisis experiences of the Southeast Asian economies, in particular, Indonesia, Malaysia, the Philippines, Singapore and Thailand -- also known as ASEAN-5. The proposition is developed that the robust economic performance of the Southeast Asian economies during the past four decades has been attributed to the various factors, developments and independent national policies which have been pursued by the individual member countries rather than to any regional economic framework. The book covers eleven topics which is suitable for a one-semester course on the economics of Southeast Asia. Also, it has a narrower area coverage as it focuses only on the five economies, namely, Indonesia, Malaysia, the Philippines, Singapore, and Thailand. The sectoral treatment of the crisis impact and the analytical treatment of policy responses to the crisis differentiate this book from other publications on the same topic. Finally, the book provides an analysis of national developments, policies and factors which have contributed to the economic transformation of the respective Southeast Asian economies.
