This book is authored for those interested in economic topics and addresses various branches of economics in some chapters to make the audience familiar with the concepts and principles of economics. Both the limitation of the scope and the necessity of covering essential and fundamental economic contents made the writer present the content succinctly. In addition to the explanations and descriptions, attempts are made to provide an overview of the economic status in Iran; therefore, Iran's economic statistics are presented in line with the subjects of different sections. Considering Iran’s Islamic culture, Islamic economic issues are also brought for each topic.
