What's the Difference?

发布时间:2019-10-09 17:32来源:凤凰彩票网采集侠字号:

If you spend much time listening to politicians or watching financial news programs on TV or on the internet, you’ve undoubtedly heard the terms “GDP” and “GNP”. The terms come up in discussions of the economy or big picture financial matters, and sometimes seem interchangeable. But what are GDP and GNP, and what is the difference between the two? 织梦好,好织梦

Both represent an attempt to measure the total economic output of a nation during a given period (usually one year), and serve as barometers to measure both the level and direction of a country’s economic activity. 本文来自织梦

GNP can be either higher or lower than GDP, depending on whether or not a country has a positive or negative result from net foreign inflows and outgo.Though GNP is still calculated, the United States shifted to GDP as its primary economic measure in 1991, in part because most countries in the world use GDP to measure the size and direction of their economies. As a result, GNP numbers are less common than GDP figures.

Both GDP and GNP are complicated, and best summarized in a side-by-side comparison: 织梦好,好织梦

Gross Domestic Product – GDP Gross National Product – GNP
What is it?   A measure of the total economyof a nation   Same as GDP  
How it’s calculated   Measuring all income earned within a country, or by measuring all expenditures within the country, which should approximately match   GDP, plus income from foreign sources, less income paid to foreign citizens and entities  
Why is it important?   It measures both the size and direction of economic activity (growth, stagnation or contraction) – expansions and recessions are based on changes in GDP   Same as GDP  
Who uses it?   Politicians, economists, large companies (especially multi-nationals)   Same as GDP  
What does it mean to me?   Shows the relative strength of the nations economy compared to that of other nations; provides a base from which to measure economic changes   Same as GDP

GDP/GNP Complications in Calculating

If you’re getting the sense that calculating either GDP or GNP is no small task, you’re absolutely right. It’s tough enough to accurately measure the true income of a household or a company, but doing so for an entire country is downright staggering. There are complications beyond simply amassing the data necessary to come up with an accurate figure. 本文来自织梦

GDP and GNP are calculated based on very specific time periods. But not all the information is available at the same time. This forces the Bureau of Labor Statistics (the agency that reports official GDP in the US) to rely on estimates, resulting in revisions after the fact.

Unreported income is another flaw, and one that is not easily remedied. Individuals may under-report income to minimize income tax liability, which will understate the GDP. This can be a problem between countries as well, since under-reporting of income is more prevalent in some countries than in others.

Still another problem — given that GDP and GNP is often used to measure economic strength from one country to another — is that reporting tends to be less reliable in some countries than in others. This is especially likely in less developed countries, leading to under-estimates of true national economic output. 织梦好,好织梦

Nominal vs. Purchasing Power Parity (PPP)

The lack of comparable reporting from one country to another has given rise to two methods of computing either GDP or GNP, nominal and purchasing power parity, or PPP. 织梦好,好织梦
