The book "Measures of National Income and Output" by Alphascript Publishing provides a comprehensive analysis of the various methods for measuring a country's or region's national income and economic output. It addresses key concepts such as Gross Domestic Product, Gross National Income, and Net National Income, all aimed at quantifying total economic activity within specific boundaries. These boundaries can be defined geographically or by citizenship, and the book highlights the challenges and limitations associated with capturing production data, particularly concerning non-monetary transactions. The authors Frederic P. Miller, Agnes F. Vandome, and John McBrewster offer an informed perspective on economic indicators and their significance for analyzing a country's economic health.
