Heritage system of Vietnam has decline because of poor-conventional condition. For sustainable development, it is required a firmly control, space planning organization, and reasonable investment. M...

CREDIT RISK MODELING USING TIME-CHANGED BROWNIAN MOTION
credit derivative Credit risk default probability first passage time
2011/8/22
Motivated by the interplay between structural and reduced form credit models, we propose to model the firm value process as a time-changed Brownian motion that may include jumps and stochastic volatil...
Statistical Inference for Time-changed Brownian Motion Credit Risk Models
Credit risk structural model rst passage problem Levy process fast Fourier transform credit default spread maximum likelihood estimation
2011/3/23
We consider structural credit modeling in the important special case where the log-leverage ratio of the firm is a time-changed Brownian motion (TCBM) with the time-change taken to be an independent i...
IS BROWNIAN MOTION NECESSARY TO MODEL HIGH-FREQUENCY DATA?
Semimartingale Brownian motion jumps finite activity infinite activity discrete sampling high frequency
2014/3/13
This paper considers the problem of testing for the presence of a continuous part in a semimartingale sampled at high frequency. We provide two tests, one where the null hypothesis is that a continuou...
Truncated Variation, Upward Truncated Variation and Downward Truncated Variation of Brownian Motion with Drift - their Characteristics and Applications
Truncated Variation Brownian Motion Applications
2010/11/3
In [6] for c > 0 we defined truncated variation, T V c μ , of Brownian motion with drift, Wt = Bt+μt, t 0, where (Bt) is a standard Brownian motion.

2010/11/1
Motivated by the interplay between structural and reduced form credit models, we propose
to model the firm value process as a time-changed Brownian motion that may include
jumps and stochastic volat...
Stock Market and Motion of a Variable Mass Spring
Stock Market Motion of a Variable Mass Spring
2010/11/1
We establish an analogy between the motion of spring whose mass increases linearly with time
and volatile stock markets dynamics within an economic model based on simple temporal demand
and supply f...
