<p>You have make a simple model to understand it more easily:</p>

<p>Jack, Diane and you all bought coupons called "share of the cake".
If you go to redeem it you will get 1/3 of the cake, because there are 3 coupons in existence.</p>

<p>But then you had your laundry disaster and suddenly there are only 2 coupons so Jack and Diane can now get 1/2 of the cake for one coupon.</p>

<p>So the answer is: other money holders benefit.
By the same principle the money holders lose purchasing power when inflation strikes. </p>

This is exactly right.  To the OP:  You had exactly the right intuition --- clearly nothing of actual value has been destroyed, so your loss must be offset by someone else's gain.  And you had exactly the right instinct --- namely, that one ought to be able to figure out who that other person is.  This answer does that.  Note in particular that the total gain to all the other moneyholders must come to exactly $100.  You can prove this with a bunch of algebra, but you can prove it more simply by noticing, as before, that nothing's been destroyed so their gain must exactly equal your loss.

It's not that easy. In partial equilibrium, yes - but what if monetary authorities respond?

If the price of a 1/3 of the cake is 1 note, why would the price of a piece of cake fall? Issue a new note? Keep a third of the cake? The answer is intuitive but builds on non-state assumptions.

@FooBar:   Yes, the monetary authorities might respond,in which case the gain is transferred to whoever gets the seignorage.  But of course, one could make the same objection to any answer to any question. "What would happen if I flipped this switch?"  "The light would go on".  "Yes, in partial equilibrium --- but what if the light attracts a burglar who cuts off the main electrical line?".  You could (quite reasonably) argue that the monetary authorities are more ubiquitous than burglars, but it still seems to me that they are outside the spirit of the question.

*"they can now issue an additional $100"* - yes, but how do they know they can? By statistics monitoring the average rate of the flow of money, and if that drops by a significant enough amount, they know that enough money has been withdrawn from circulation that they can issue more?

obviously its hard to notice $100, but if you destroy enough currency it will start deflating prices and that will act as a signal to print more money.

<p>Nobody won, you have just lost 100 \$  :) you made a contractionnary monetary policy with a $10^{-1000000000000}$ amplitude on economy. It means that you have reduced the quantity of money in whole economy which will have the same effects (but very very tiny) of a contractionnary monetary policy of a central bank.</p>

I'd like very much to know a) what "amplitude on the economy" means, b) how you calculated that exponent, and c) whether the same exponent would apply to any other transfer of $100.

I think you are deviating the conversation :) I don't think that you are naive to believe that destroyed 100 \$ (as OP said in his question) could have some considerable effects on whole economy. The effect is so minor. Also, there does not exist any transfer according to OP's question. The money is destroyed in laundry which means that there is a reduction of quantity of money in circulation.

@BCLC Nobody won this money (in the sense that there is not a transfer and nobody took this 100 \$ ) because it is destroyed. However, there is a very very tiny effect on the whole economy beaucause the amount of money in circulation decreases. That's the idea.

@BCLC yes no one won the whole 100 \$ but agents in economy will see the effect on their wallet ! As this 100 \$ is destroyed, the quantity of money in circulation is decreased, which will increase the value of \$ with respect to other currencies
Let' say person A holds 10.000 € and person B holds 10.000 \$. In this case, person B will win (By the way, I don't think the word win is appropriate) and person A will loose as the value of \$ increases according to €.

@EnergyNumbers Arguably, real output should be uneffected, so if no real output is wasted, this should have redistributive effects. I think this is a really good question.

You have make a simple model to understand it more easily:

Jack, Diane and you all bought coupons called "share of the cake".
If you go to redeem it you will get 1/3 of the cake, because there are 3 coupons in existence.

But then you had your laundry disaster and suddenly there are only 2 coupons so Jack and Diane can now get 1/2 of the cake for one coupon.

So the answer is: other money holders benefit.
By the same principle the money holders lose purchasing power when inflation strikes.

My intuition says that theoretically the disappearance of 100 $ from the money supply should increase the value of all other money in circulation so everyone else with any money gains a marginal benefit that is higher the more money they have.

The benefit a person gains = (100$/total money supply)\*(amount of money held by the person)

The disappearance has to be public knowledge, though, so the market can take it into account.
