Much of the money might have been donated anyway, but Mr. Buffett said the value of the pledges lies in the examples they set and in the sentiments expressed by the contributors in letters posted on the campaign's Web site.
Proof of theorem 3: According to Merton (1973), theorem 9, if the probability distribution of the pledged assets yield does not depend on the value of the pledged assets V, the value of the put option is a homogeneous function of the strike price and the current value of the pledged assets.
Theorem 3: If the probability distribution of the pledged assets yield does not depend on the value of the pledged assets V, then x does not depend on V, and the loanable amount is a linear function of the value of the pledged assets.
Suppose that the price of a pledged property follows a geometric Brownian motion, the value of the pledged property is P, the lending moment is 0, and the interest paid each time is RxV 0).
The economic implication is that if the value of the pledged property is greater than the value of the loan, the borrower should not give up the pledged property and should not default, and if the pledged property value is less than the value of the loan, the borrower should not continue to repay the loan and should default.
In his case, this cuts the value of the pledge by nearly £8,000.
This may involve higher margin payments or a bigger "haircut" shaved off the value of assets pledged as collateral.
Magistrate Judge Roanne L. Mann agreed to release Mr. Yushuvayev on $500,000 bond, but only after the court received proof of the value of homes pledged as security by his father, an immigrant from Uzbekistan.
He said he thought the real value of the pledge was found in the example that it set and in the sentiments expressed in the letters posted on the Web site.
