What Is Gross National Product?

Gross National Product (GNP) is a macroeconomic indicator that measures the total market value of all finished goods and services produced by a country's residents, regardless of their location, in a given period, typically a year. It falls under the broader financial category of national income accounting, which tracks the economic activity and wealth of a nation. Unlike other common measures, GNP includes income earned by domestic residents from their investments abroad, while excluding income earned by foreign residents within the domestic economy. This provides a perspective on the economic output attributable to a nation's citizens and corporations. Understanding GNP is crucial for economic analysis and evaluating a country's overall economic performance.

History and Origin

The concept of national income measurement gained prominence in the early 20th century, particularly during the Great Depression, when policymakers needed better data to understand and address economic downturns. In the United States, Gross National Product was the primary measure of the nation's total economic output for many decades, notably from 1934 until 1991. During this period, the Bureau of Economic Analysis (BEA), an agency of the U.S. Department of Commerce, extensively used and reported GNP figures. However, in November 1991, the BEA made a significant shift, replacing GNP with gross domestic product (GDP) as its featured measure of U.S. production. This change was largely driven by the increasing globalization of economies and the need for a measure that more accurately reflected domestic production, aligning the U.S. with international standards like the System of National Accounts (SNA). The BEA outlined this change in its reporting, highlighting the advantages of GDP for short-term economic monitoring and international comparisons.⁷

Key Takeaways

• Gross National Product (GNP) quantifies the total market value of final goods and services produced by a country's residents, both domestically and abroad.
• It includes income from overseas investments by domestic residents and excludes income earned by foreign residents within the country.
• GNP was historically a key economic indicator in the U.S. before being largely replaced by Gross Domestic Product (GDP) in 1991.
• While less frequently used than GDP today, GNP can still offer unique insights into a nation's economic ties to the global economy.

Formula and Calculation

The Gross National Product can be calculated using various approaches, but a common method is to adjust the Gross Domestic Product (GDP) to account for net factor income from abroad. The formula is:

Where:

• GDP (Gross Domestic Product) represents the total monetary value of all final goods and services produced within a country's geographical borders during a specified period.
• Net Factor Income From Abroad (NFIA) is the difference between the income that a country's residents earn from their investments and labor abroad, and the income that foreign residents earn within the country. This can include wages, profits, and interest payments.

Alternatively, GNP can be calculated using an expenditure approach, similar to GDP:

Where:

• C = Consumption (personal consumption expenditures)
• I = Gross Private Domestic Investment
• G = Government Spending (government consumption expenditures and gross investment)
• (X - M) = Net Exports (exports minus imports of goods and services)

Interpreting the Gross National Product

Interpreting the Gross National Product involves understanding what the figure represents and how it reflects a nation's economic standing. A higher GNP generally suggests a nation's residents and businesses are generating substantial income, both from domestic activities and from their operations and investments in other countries. It emphasizes the income earned by a country's citizens, providing a measure of economic strength that accounts for global economic engagement. For example, if a country's multinational corporations have significant operations abroad, their profits repatriated to the home country would contribute to a higher GNP. While GNP is not as widely used as GDP for short-term economic monitoring, its value lies in providing insights into the economic well-being of a nation's citizens, including those living or working overseas, and the impact of foreign investment on the national income.

Hypothetical Example

Consider the hypothetical country of "Diversifia." In a given year, Diversifia's Gross Domestic Product (GDP) is calculated to be $10 trillion. This represents all the goods and services produced within its borders.

However, Diversifia's citizens and companies also own numerous factories and businesses in neighboring countries, from which they earn $500 billion in profits and wages that are sent back to Diversifia. Simultaneously, foreign companies operating within Diversifia's borders send $200 billion in profits back to their home countries.

To calculate Diversifia's Gross National Product (GNP):

1. Start with GDP: $10 trillion
2. Calculate Net Factor Income From Abroad:
   • Income earned by Diversifia's residents abroad: $500 billion
   • Income earned by foreign residents in Diversifia: $200 billion
   • Net Factor Income From Abroad = $500 billion - $200 billion = $300 billion
3. Add Net Factor Income From Abroad to GDP:
   • GNP = $10 trillion + $300 billion = $10.3 trillion

In this scenario, Diversifia's GNP of $10.3 trillion indicates that the total economic output attributable to its citizens and businesses, considering their global activities, is greater than its domestic output alone. This highlights the importance of analyzing factors like cross-border trade when assessing a nation's economic reach.

Practical Applications

While Gross National Product has largely been superseded by Gross Domestic Product as the primary measure of economic growth, it still holds practical applications in specific contexts, particularly in macroeconomic analysis. GNP can be particularly useful when a country's citizens and companies have significant economic activities and investments overseas. It provides a more accurate picture of the income accruing to the residents of a country, regardless of where that income is generated. For instance, countries with substantial outward foreign direct investment or a large diaspora sending remittances often find GNP a valuable metric for understanding national income. International organizations like the World Bank continue to collect and provide data on Gross National Income (GNI), which is closely related to GNP and often used interchangeably for international comparisons, reflecting the total income received by a country from its residents and businesses, including those abroad.⁶

Limitations and Criticisms

Despite its utility, Gross National Product faces several limitations and criticisms. One significant drawback, shared with GDP, is that GNP does not fully account for factors such as income inequality, environmental degradation, or the value of unpaid work, such as household services or volunteer efforts.⁵ For example, a country's GNP might rise due to increased production, but this growth could come at the cost of depleted natural resources or a wider gap between rich and poor, none of which are reflected in the aggregate figure. Critics argue that GNP, like GDP, primarily measures economic output rather than true societal well-being or standard of living.

Furthermore, calculating GNP accurately can be challenging due to the complexities of tracking international income flows, particularly in a globalized economy with intricate multinational corporate structures and global supply chains. Issues such as transfer pricing and the mobility of capital can make precise measurement difficult. There are also arguments that a focus solely on aggregate measures like GNP can incentivize short-term growth at the expense of long-term sustainability or broader social indicators.⁴ The difficulty in precisely measuring improvements in the quality of goods and services or accounting for depreciation of capital stock also poses challenges for accurate GNP estimation.

Gross National Product vs. Gross Domestic Product

The key difference between Gross National Product (GNP) and Gross Domestic Product (GDP) lies in their scope concerning geographical boundaries versus ownership.

For instance, if a U.S.-owned company operates a factory in Mexico, the output of that factory would contribute to Mexico's GDP because it's produced within Mexico's borders. However, the profits repatriated by that U.S. company would contribute to the U.S.'s GNP, as it represents income earned by a U.S. entity, regardless of location.³ Conversely, profits earned by a Japanese company's factory in the U.S. would count towards U.S. GDP but Japanese GNP.² While GDP is now the more commonly used measure for comparing national economies, especially for short-term economic monitoring and analyses of domestic economic activity, GNP remains relevant for understanding a country's total income derived from its national factors of production, both at home and abroad. The choice between using GNP or GDP often depends on the specific aspect of economic performance being analyzed, with the trade balance being a critical component in both calculations.

FAQs

What does a higher GNP indicate for a country?

A higher Gross National Product (GNP) generally indicates that a country's residents and businesses are generating more income, both from domestic production and from their investments and activities in other nations. It suggests a strong global economic footprint for the nation's entities.

Why did the U.S. switch from GNP to GDP as its main economic indicator?

The U.S. switched from GNP to GDP in 1991 to align its primary economic measurement with international standards. GDP was considered a more appropriate measure for analyzing domestic production, particularly in an increasingly globalized economy where cross-border production activities were becoming more significant.¹

Is GNP still used today?

While Gross National Product (GNP) is not as widely publicized or used as Gross Domestic Product (GDP) for general economic reporting, it is still a relevant metric. It is often considered by economists and policymakers who need to understand the total income accruing to a nation's residents, including income from foreign sources, and its role in assessing a country's economic stability.

How does GNP relate to a country's balance of payments?

GNP is closely related to a country's balance of payments because it incorporates net factor income from abroad. This component directly reflects the difference between income flows into and out of a country due to foreign investments and remittances, which are key elements of the current account in the balance of payments.
