How a bubble is built?

Once there was a little island country. The land of this country was the tiny island itself. The total money in circulation was 2 dollars as there were only two pieces of 1 dollar coins circulating around.
1) There were 3 citizens living on this island country. A owned the land. B and C each owned 1 dollar.
2) B decided to purchase the land from A for 1 dollar. So, now A and C own 1 dollar each while B owned a piece of land that is worth 1 dollar.
* The net asset of the country now = 3 dollars.
3) Now C thought that since there is only one piece of land in the country, and land is non producible asset, its value must definitely go up. So, he borrowed 1 dollar from A, and together with his own 1 dollar, he bought the land from B for 2 dollars.
* A has a loan to C of 1 dollar, so his net asset is 1 dollar.
* B sold his land and got 2 dollars, so his net asset is 2 dollars.
* C owned the piece of land worth 2 dollars but with his 1 dollar debt to A, his net residual asset is 1 dollar.
* Thus, the net asset of the country = 4 dollars.
4) A saw that the land he once owned has risen in value. He regretted having sold it. Luckily, he has a 1 dollar loan to C. He then borrowed 2 dollars from B and acquired the land back from C for 3 dollars. The payment is by 2 dollars cash (which he borrowed) and cancellation of the 1 dollar loan to C. As a result, A now owned a piece of land that is worth 3 dollars. But since he owed B 2 dollars, his net asset is 1 dollar.
* B loaned 2 dollars to A. So his net asset is 2 dollars.
* C now has the 2 coins. His net asset is also 2 dollars.
* The net asset of the country = 5 dollars. A bubble is building up.
(5) B saw that the value of land kept rising. He also wanted to own the land. So he bought the land from A for 4 dollars. The payment is by borrowing 2 dollars from C, and cancellation of his 2 dollars loan to A.
* As a result, A has got his debt cleared and he got the 2 coins. His net asset is 2 dollars.
* B owned a piece of land that is worth 4 dollars, but since he has a debt of 2 dollars with C, his net Asset is 2 dollars.
* C loaned 2 dollars to B, so his net asset is 2 dollars.
* The net asset of the country = 6 dollars; even though, the country has only one piece of land and 2 Dollars in circulation.
(6) Everybody has made money and everybody felt happy and prosperous.
(7) One day an evil wind blew, and an evil thought came to C's mind."Hey, what if the land price stop going up, how could B repay my loan.
There is only 2 dollars in circulation, and, I think after all the land that B owns is worth at most only 1 dollar, and no more."
(8) A also thought the same way.
(9) Nobody wanted to buy land anymore.
* So, in the end, A owns the 2 dollar coins, his net asset is 2 dollars.
* B owed C 2 dollars and the land he owned which he thought worth 4 dollars is now 1 dollar. So his net asset is only 1 dollar.
* C has a loan of 2 dollars to B. But it is a bad debt. Although his net asset is still 2 dollars, his Heart is palpitating.
* The net asset of the country = 3 dollars again.
(10) So, who has stolen the 3 dollars from the country? Of course, before the bubble burst B thought his land was worth 4 dollars.
Actually, right before the collapse, the net asset of the country was 6 dollars on paper. B's net asset is still 2 dollars, his heart is palpitating.
(11) B had no choice but to declare bankruptcy. C as to relinquish his 2 dollars bad debt to B, but in return he acquired the land which is worth 1 dollar now.
* A owns the 2 coins; his net asset is 2 dollars.
* B is bankrupt; his net asset is 0 dollar. (He lost everything)
* C got no choice but end up with a land worth only 1 dollar
* the net asset of the country = 3 dollars.
************ **End of the story; ************ ********* ******
BUT
There is however a redistribution of wealth.
A is the winner, B is the loser, C is lucky that he is spared.

A few points worth noting -
(1) when a bubble is building up, the debt of individuals to one another in a country is also building up.
(2) This story of the island is a closed system whereby there is no other country and hence no foreign debt. The worth of the asset can only be calculated using the island's own currency. Hence, there is no net loss.
(3) An over-damped system is assumed when the bubble burst, meaning the land's value did not go down to below 1 dollar.
(4) When the bubble burst, the fellow with cash is the winner. The fellows having the land or extending loan to others are the losers. The asset could shrink or in worst case, they go bankrupt.
(5) If there is another citizen D either holding a dollar or another piece of land but refrains from taking part in the game, he will neither win nor lose. But he will see the value of his money or land goes up and down like a see saw.
(6) When the bubble was in the growing phase, everybody made money.
(7) If you are smart and know that you are living in a growing bubble, it is worthwhile to borrow money (like A) and take part in the game. But you must know when you should change everything back to cash.
(8) As in the case of land, the above phenomenon applies to stocks as well.
(9) The actual worth of land or stocks depends largely on psychology (or speculation)

Actually story did not stop there. Since bubble burst, there was not food, no vegetable or anything to sell in the market. The fellow with a dollar tried hard to get some from fellow with land who had no surplus and so he d**d of hunger ultimately.. So was the fellow , who lent money but could not get it back. The fellow with land went back to grow some foodgrain and vegetables and survived and had to take care of of the other two. He could get one dollar for that which was useless as there was no market to buy anything.

This is exactly what happened with the sub-prime loans. The MTM valuations of the sub-prime tranche never showed any losses initially because there were greater fools to buy these loans.
The moment the buyers disappeared, banks had to start writing down the losses as the valuation of these sub-prime loans started falling down.

And then there were fools who were outbidding each other to buy stocks - unlike land, stocks can be easily produced (manufactured) via rights, follow-on issue, convertible debentures etc.

In 2000, 25 shares of Reliance would buy you 1 sq.ft of property in Central Mumbai. Today, (adjusting for splits, bonuses and dividends) 15 shares of Reliance would buy you 1 sqft. At the peak of the bubble (Jan 2008), 6 shares of Reliance would allow you to buy 1 sqft of the same property.

Thanks Adheer, very nice Article!!!!

Can we explain Japan's real estate boom in 90's with to this model?Japan's savings rate had always been high[the national debt doesnt increase], but for a bubble to form speculative cash should be there.
