Yes, thank you for proving my point. How people elect to spend their income affects GDP, thus income does not equal GDP. Have you figured it out yet?

You are looking at this the wrong way, from an individual perspective. National economy is about production, not consumption. Income is something that has already been earned, not something you choose to spend. Production comes first, and then expenditure gives it value and turns it into income. The way GDP is defined, the sum of domestic production in a time period is always the same as the sum of domestic expenditure and the sum of domestic income. If someone buys Chinese goods, they contribute to Chinese production, expenditure, and income.

  If I earn a dollar and don't spend it, it results in a lower GDP than if I spent it. Thus income can not be treated as equivalent to GDP. We're talking about a very straightforward and obvious definition here. No need to confuse people

    You clearly misunderstand what income is then. If you receive an income, someone had to spend money (in this case your employer). So it does in fact contribute to GDP, as your employer spent money buying your service/finished work. So income you received already contributed to GDP, even if it just sits in your bank account. Now if you go onto spend it, it will further increase GDP, as you spending it will yield an income for someone else. If you leave it in the bank account, it will not further increase GDP, as it won't yield anyone an income. Additionally, when a US citizen buys a Chinese good, it does in fact contribute to GDP - namely China's GDP. If it's not clear to you by now, GDP is almost the same exact thing as money velocity, just divide it by the money supply and you have the velocity of money.

      I'm not sure how you all are misunderstanding adam_arthur. GP wrote: > If I earn a dollar and don't spend it, it results in a lower GDP than if I spent it. You disagreed. Here's the situation: Today I earn $10. I then do one of two things: 1 I save it for a rainy day. 2 I buy something with all $10. In scenario two, GDP went up $10 over scenario one.

        Define "save for a rainy day". Are you talking about permanently putting it under your matress, leaving it in your checking account, or investing it? It will eventually be spent, and the only thing that is changing is the velocity. Either way, that is not necessarily correct. GDP has multiple different calculations: Y = C + I + G + NX or GDP = Consumption + Investment + Government Spending + Net Exports Another calculation is Y = C + S + T GDP = Consumption + Saving + Net Taxes Saving either through investment and cash hoarding both count toward GDP. The percentage of GDP that is Saving is the Gross National Savings or National Savings Rate. tldr; In isolation, scenario 1, Investment is $10 as inventory and Savings is $10. Both add toward GDP https://en.wikipedia.org/wiki/National_saving https://en.wikipedia.org/wiki/National_saving

        The issue is the next sentence: > Thus income can not be treated as equivalent to GDP. GDP is defined as total income, calculated in a certain way. There are also other equivalent definitions. Income is the endpoint of economic activity. Your income contributes to the GDP when you earn it. Your spending is largely unrelated to your income. In any period of time, you can spend more than you earn or less than that. Spending creates new economic activity. That activity contributes to the GDP, which by definition means creating new income.

        I think you missed why I am failing to understand this one. The full context there is: > If I earn a dollar and don't spend it, it results in a lower GDP than if I spent it. Thus income can not be treated as equivalent to GDP. It's the second part that I don't understand. Those two sentences read to me like: "Spending decisions impact GDP, therefore income is not equivalent to GDP." I don't think anyone is claiming that spending would fail to increase GDP. But I still don't see how income is disconnected from GDP, since that spending would be someone else's income.
