National income and products estimates are used extensively worldwide. During the 1950's P. Studenski's work `The Income of Nations' became a classic on the topic. With more extensive compilations, more sophisticated applications, the results and methodology and far reaching international agreements, the international comparability in accounts is now insured. This volume supplements the earlier research in national accounting with a historical overview that shows the development in national income and product accounts. Readers: researchers and professionals in economy, statistics and accounting.
