  • Valuation of a repriceable executive stock option

    Takahiko Fujita, Masahiro Ishii

    Asia-Pacific Financial Markets   17 ( 1 )   1 - 18   2010.2

     More details

    Language:English  

    We introduce a path-dependent executive stock option. The exercise price might be reduced when both the firm's stock price and a stock market index fall greatly. The repriceable executive stock option has a simple payoff that may be used for realistic executive rewards. We show the valuation formula, and compute the probability of the repriceable executive stock option expiring in-the-money. Both price and probability are important pieces of quantitative information when choosing an executive compensation package. © Springer Science+Business Media, LLC. 2009.

    Language:English  

    This article will be started with a fundamental observation on consecutive nonnegative integers. Based on the observation, we will demonstrate that the sequence of nonnegative integers is regarded as a uniformly distributed sequence in the ring of the p-adic integers. As a result, the sequence provides us with a faster rate of convergence than the one obtained by simply applying law of the iterated logarithm. © de Gruyter 2008.

  • A random walk analogue of Lévy's Theorem

    Studia Scientiarum Mathematicarum Hungarica   45 ( 2 )   223 - 233   2008.6

     More details

    Language:English  

    In this paper we will give a simple symmetric random walk analogue of Lévy's Theorem. We will give a new definition of a local time of the simple symmetric random walk. We apply a discrete It formula to some absolute value like function to obtain a discrete Tanaka formula. Results in this paper rely upon a discrete Skorokhod reflection argument. This random walk analogue of Lévy's theorem was already obtained by G. Simons ([14]) but it is still worth noting because we will use a discrete stochastic analysis to obtain it and this method is applicable to other research. We note some connection with previous results by Csáki, Révész, Csörg and Szabados. Finally we observe that the discrete Lévy transformation in the present version is not ergodic. Lastly we give a Lévy-type theorem for simple nonsymmetric random walk using a discrete bang-bang process. © 2008 Akadémiai Kiadó.

    A new class of s-dimensional uniformly distributed sequences called the generalized van der Corput sequence is defined. The sequence is constructed by using the generalized number system based on an integer matrix whose all eigenvalues reside out of the unit circle. In this talk, we show that by using the generalized van der Corput sequence we can calculate numerical integrations with the convergence speed O(l/N) when integrands satisfy some regularity conditions. We also apply the sequence to a numerical Integration problem and test effectiveness of the sequence. © KSP 2002.
