The GDP being measured is that of the pair, not the man.

Before marriage: 175 I + 50 of consume (the man consumes 25 in the form of a clean home, his maid consumes 25 to buy shoes) = 225.

After marriage: 175I + 25 of consume (the 25 consumed by the wife to buy shoes) = 200.

By the way, your question is good, and I really wish HN wouldn't reflexively downvote stuff they don't agree with.

Let's say the man invests all his money in a socks business. In the first case his socks business will demand 25k less. The maid will demand 25k more. I still see effect 0. I think the problem is people are not considering savings in the equation...

In the first scenario, the income of the man is 200K and the income of the woman is 25K. For a total income of 225K. It doesn't matter where the money comes from or is going. That's the income both will write on the federal returns or whatever you want, for the sake of the example.

When they get married, the man's income stays the same. The woman's income evaporates. She's not getting paid anymore. So their combined income is now 200K.

But the situation is exactly the same! The same amount of work is being done.

GDP works exactly the same way. It's an account of money flows, not production or actual economic activity.

Again, in the first case the man is simply spending the 25k on the maid. In the second case he will spend the 25k in something else. That something else will then spend the 25k as the maid would have done. No change.

Again, in the first case the man is simply spending the 25k on the maid. In the second case he will spend the 25k in something else.

Again, you are looking at the GDP of the man, not of the pair of people.

Because the man first spends 25k, and then the maid spends 25k again, the 25k is counted twice in GDP statistics. In the second case, it is counted once.

This is why GDP != Income.

[viandante]

Well, let's say that now that he saves 25k for the maid, he hires a gardner. GDP 225 again? So basically the GDP depends on the number of transactions? Is that so?

[maratd]

Yes, that is so. GDP = Gross Domestic Product. It's gross. Not net. There is no saving, no subtraction of any kind. Just addition.
