Economic growth and structural change - the future of the world economy - is analysed in this book. Conditional forecasts are given for the economic development of the most important world market countries till the year 2000. The driving forces of economic growth are identified and forecasted, in connection with collaborating scholars in most of these countries and with international organizations. This information is used in solving a coherent world model. The model consists of linked growth models for each country (or groups of countries). The solutions show that the inequality in international income distribution will further increase and that the CMEA and OECD countries will approximately keep their relative positions, with some changes within these groups. Structural change is also analysed. Additionally separate forecasts prepared by each collaborating country group are given and may be compared with the forecasts by the world model. The book closes with chapters on special features of the future economic development: on the international debt problem, on long waves, on structural change in the world trade, on the emergence of service economics and on the comparison of GDP and NMP national accounting.
