📖 1. Conceptual framework for measuring national wealth and economic activity

🔑 Key Concepts & Definitions

• Economic system : A structure that defines how an economy operates, including its functioning and objectives, necessary for describing economic processes.
• Economic activity : The production, income generation, consumption, investment, and wealth within a country, measured through national accounts.

📝 Essential Points

• Describing how an economy functions requires a conceptual framework that defines what an economic system is, how it operates, and what its objectives are.
• Appropriate measurement tools alone are insufficient without a conceptual framework to interpret economic phenomena.
• The aspiration to increase national wealth reflects a broader societal desire to improve living conditions.
• The definition chosen for a country’s wealth shapes the way that wealth is measured.
• • Describing how an economy functions is by no means straightforward.

💡 Key Takeaway

Describing how an economy functions requires a conceptual framework that defines what an economic system is, how it operates, and what its objectives are.

📖 2. Historical perspectives on the origin and measurement of wealth

🔑 Key Concepts & Definitions

• Origin of wealth : A fundamental question in economic theory concerning the foundations of a nation's wealth and the means by which it can be increased.
• Paris 1 – Ecole d’économie : The economics school of the University of Paris 1, also known as Ecole d’économie de la Sorbonne, where economic theories on wealth have been studied and taught.
• University of Paris 1 – Ecole : An institution of higher education, specifically the University of Paris 1, which includes the Ecole d’économie de la Sorbonne.

📝 Essential Points

• Human beings can increase wealth through production, conquest, or theft, but only production leads to absolute growth.
• Early economic thought aimed to establish a single standard to express different components of wealth.
• The circulation of wealth among social classes and nations was an early focus, leading to flow-based conceptions of wealth.
• The aspiration to increase wealth has been a recurring question throughout economic history.
• 10 15/01/2026 6 Isabelle HIRTZLIN – University of Paris 1 – Ecole d’économie de la Sorbonne (EES)
• The objective then becomes to establish a single standard by which the different components of wealth can be expressed,
• and to demonstrate how this wealth circulates among social classes and across nations—hence the emergence of a conception framed in terms of flows of wealth.
• 8 15/01/2026 5 Isabelle HIRTZLIN – University of Paris 1 – Ecole d’économie de la Sorbonne (EES) History of the conception of wealth 29/09/2015 9 Isabelle HIRTZLIN – University of Paris 1 – Ecole d’économie de la Sorbonne (EES)
• Quite early on, it becomes apparent that human beings are capable of increasing their wealth through various means:
• by stealing,
• by conquering territories (that is, not through absolute growth but by dispossessing others),
• and above all, through human production (Initially, through the cultivation of land, the exploitation of forests, and livestock farming).

💡 Key Takeaway

Historical views on wealth emphasize its origins and the challenge of expressing diverse wealth components in a unified measurement system.

📖 3. Physiocratic model and François Quesnay's Tableau Économique

🔑 Key Concepts & Definitions

• Tableau Économique : 11 Isabelle HIRTZLIN – University of Paris 1 – Ecole d’économie de la Sorbonne (EES) François Quesnay (1694-1774)

• The Tableau Économique by François Quesnay is considered the first systematic model of an economy, created in 1758– 1759.

• Physiocratic school : It represents the circulation of wealth within a nation and laid the foundations of the Physiocratic school of thought.

📝 Essential Points

• Quesnay’s Tableau Économique (1758–1759) is the first systematic economic model representing wealth circulation within a nation.
• Physiocrats argued that only agriculture produces a net product (surplus), while other sectors merely transform wealth.
• The economy is divided into three social classes: productive (farmers), proprietary (landowners), and sterile (artisans, merchants).
• The Tableau emphasizes the circular flow of income through rents, consumption, and reinvestment sustaining the economy.

💡 Key Takeaway

Quesnay’s Tableau Économique (1758–1759) is the first systematic economic model representing wealth circulation within a nation.

📖 4. Classical, Neoclassical, and Keynesian views on wealth and value

🔑 Key Concepts & Definitions

• Classical school : An economic tradition that considers the quantity of labor embodied in goods as the determinant of their value, with key figures including Adam Smith and David Ricardo.
• Labor theory of value : A theory stating that the exchange value of commodities is created by the labor time required to produce them, which becomes embedded in the commodity itself.

📝 Essential Points

• Neoclassical economists reject the labor theory of value, defining value based on utility and market efficiency.
• Marx critiqued classical views, highlighting surplus value produced by the proletariat as the source of social power.
• Keynes shifted focus from produced wealth to consumed wealth, emphasizing demand and final consumption.

💡 Key Takeaway

Diverse economic schools offer contrasting foundations for wealth and value, shaping how economic activity is understood and measured.

📖 5. Development and institutionalization of national accounts after World War II

🔑 Key Concepts & Definitions

• National accounts : A systematic framework developed after World War II to provide precise data on a country's economic activities, enabling governments to manage wartime economies and plan post-war recovery.
• Simon Kuznets : An economist who developed the first systematic national income estimates for the United States in 1934.
• Richard Stone : An economist who, in the United Kingdom during World War II, introduced double-entry principles to national income accounting to provide quantitative frameworks for wartime resource mobilisation and peacetime reconstruction.
• Marshall Plan : 22 15/01/2026 12 Isabelle HIRTZLIN – University of Paris 1 – Ecole d’économie de la Sorbonne (EES) The Link with the Marshall Plan
• The Marshall Plan, named after a United States Secretary of State, was an extensive programme of financial aid from the United States and Canada to the European countries that had been devastated byWorldWar II.

📝 Essential Points

• The Marshall Plan, providing financial aid from the U.S. and Canada to Europe after World War II, accelerated the development of standardized national accounts.
• The OEEC published the first international System of National Accounts in 1952, which was adopted and revised by the United Nations in 1953.
• • The result of Stone’s work, A Standardised System of National Accounts published by the OEEC in 1952, can fairly be described as the first international system (1953 System of National Accounts).

💡 Key Takeaway

The urgent post-World War II need for precise economic data catalyzed the creation and international standardization of national accounts, making them essential tools for economic management.

📖 6. Gross Domestic Product (GDP) as the central indicator and emerging concepts in wealth measurement

🔑 Key Concepts & Definitions

• Gross Domestic Product (GDP) : An international economic indicator that summarizes the total value of goods and services produced within a country's borders, used to assess the health of the economy through the rate of production growth.
• Ecological footprint : A concept related to wealth measurement that reflects concerns about sustainability and the environmental impact of economic activities.
• Green GDP : A concept emerging in wealth measurement that attempts to incorporate environmental and ecological considerations into the traditional GDP indicator.

📝 Essential Points

• GDP is the dominant international indicator summarizing economic health through production growth.
• Modern GDP includes diverse production, notably services which now constitute over three-quarters of national output.
• • This indicator still relies on the classical authors’ central notion of production, but today very different things can be produced, notably services (market or non-market—free or nearly free), which now account for more than three- quarters of national production.

💡 Key Takeaway

GDP is the dominant international indicator summarizing economic health through production growth.

📖 7. European System of Accounts (ESA), Eurostat, and national institutions in France

🔑 Key Concepts & Definitions

• European System of Accounts (ESA) : A European regulation adopted in 1996 that standardizes national accounts across EU member states, binding all members to a common framework.
• Eurostat : The statistical office of the European Union, based in Luxembourg, responsible for coordinating, harmonizing, and publishing comparable economic statistics across EU member states.
• Directorate General of the Treasury : A directorate of the French Ministry of the Economy, Industry, and Employment responsible for managing accounts of the rest of the world, economic forecasts, and macroeconomic policy analysis.

📝 Essential Points

• ESA95, adopted in 1996 and revised as ESA2010, is a binding European regulation standardizing national accounts across EU member states.
• Eurostat coordinates and harmonizes economic statistics to ensure comparability within the EU.
• In France, INSEE prepares business and household accounts and summary tables, operating under the Ministry of Economy.
• The Directorate General of the Treasury manages accounts of the rest of the world and economic forecasts in France.

💡 Key Takeaway

ESA95, adopted in 1996 and revised as ESA2010, is a binding European regulation standardizing national accounts across EU member states.

📖 8. Methodological approaches in national accounts: production and income approaches

🔑 Key Concepts & Definitions

• Production approach : An approach in national accounting that measures economic activity by the value of goods and services created and destroyed, reflecting the creation of value embodied in these goods and services.
• Income approach : An approach in national accounting that presents income flows generated by production, such as wages paid by corporations, representing the distribution of national income among institutional sectors.
• Monetary flows : Flows measured in monetary units representing the circulation of goods and services in national accounts, enabling aggregation despite the heterogeneous units of measurement of actual goods and services.
• Resident units : Institutional units recorded in ESA 2010 that have their center of predominant economic interest in the economic territory of a country, regardless of nationality, legal form, or presence at the time of transaction.

📝 Essential Points

• Monetary units are used to measure heterogeneous goods and services flows, enabling aggregation in national accounts.
• Economic activity units recorded in ESA 2010 are resident units with predominant economic interest in the country, regardless of nationality.

💡 Key Takeaway

Economic activity units recorded in ESA 2010 are resident units with predominant economic interest in the country, regardless of nationality.
