Abstract:

The thesis dealing with topics under model uncertainty consists of two main parts. In the first part, we introduce a reduced-form framework in the presence of multiple default times under model uncertainty. In particular, we define a sublinear conditional operator with respect to a family of possibly non-dominated priors for a filtration progressively enlarged by multiple ordered defaults. Moreover, we analyze the properties of this sublinear conditional expectation as a pricing instrument and consider an application to insurance market modeling with non-linear affine intensities.

Abstract:

In this study Jarrow Turnbull (1995) Model, which is a reduced form approach for credit risk models, is employed to estimate the default intensity of US corporate bonds conditionally based on a fixed recovery rate. The estimations are performed with respect to the ratings of the bonds and the results were consistent with the ratings. US Treasury Bills are also used to since zero coupon default free prices, modeled by Svensson (1994) are necessary for pricing the default risky coupon bonds.

Sensitivity analysis based on a chemical transport model (CTM) serves as an important approach towards better understanding the relationship between trace contaminant levels in the atmosphere and emissions, chemical and physical processes. Previous studies on ozone control identified the high-order Decoupled Direct Method (HDDM) as an efficient tool to conduct sensitivity analysis. Given the growing recognition of the adverse health effects of fine particulate matter (i.e., particles with an aerodynamic diameter less than 2.5 micrometers (PM2.5)), this dissertation presents the development of

Abstract:

Since the default of Lehman Brothers in 2008, it has become increasingly important to measure, manage and price the default risk in financial derivatives. Default risk in financial derivatives is referred to as counterparty credit risk (CCR). The price of CCR is captured in Credit Valuation Adjustment (CVA). This adjustment should in principle always enter the valuation of a derivative traded over-the-counter (OTC). To calculate CVA, one needs to know the probability of default of the counterparty. Since CVA is a price, what one needs is the risk-neutral probability of default. The typical way

Abstract:

Across all engineering disciplines, the differences found between experimental results and computational simulations gives rise to various degrees of uncertainty in the solutions. In fluid dynamics these differences can be broadly split into issues of boundary conditions and numerical accuracy. Within the computational fluid dynamics (CFD) community a great deal of effort has been invested in reducing numerical error, yet large discrepancies with experimental data persist. The nature of experimental and computational studies often dictates the application of different boundary conditions appli

The thesis covers a wide range of topics from the credit risk modeling with the emphasis put on pricing of the claims subject to the default risk. Starting with a separate general contingent claim pricing framework the key topics are classified into three fundamental parts: firm-value models, reduced-form models, portfolio problems, with a possible finer sub-classification. Every part provides a theoretical discussion, proposal of self-developed methodologies and related applications that are designed so as to be close to the real-world problems.

This dissertation contains work that addresses both theoretical and numerical aspects of reduced order models (ROMs). In an under-resolved regime, the classical Galerkin reduced order model (G-ROM) fails to yield accurate approximations. Thus, we propose a new ROM, the data-driven variational multiscale ROM (DD-VMS-ROM) built by adding a closure term to the G-ROM, aiming to increase the numerical accuracy of the ROM approximation without decreasing the computational efficiency. The closure term is constructed based on the variational multiscale framework. To model the closure term, we use d

Head-Related Impulse Responses (HRIRs) are used in signal processing to implement the synthesis of spatialized audio. They represent the modification that sound undergoes from its source to the listener's eardrums. HRIRs are somewhat different for each listener and require expensive specialized equipment for their individual measurement. Therefore, the development of a method to obtain customized HRIRs without specialized equipment is extremely desirable. A customizable representation of HRIRs can be created by modeling them in terms of an appropriate set of time delays and a resonant frequenc

This thesis concerns itself with a finite element model of nonproportional viscoelastic damping and its subsequent reduction.

Unlike previous models, it incorporates physical data into the model in the form of a curve fit of the complex modulus. This curve fit is expressed by minioscillators. The frequency dependence of the complex modulus is accounted for by the addition of internal, or dissipation, coordinates. The dissipation coordinates make the viscoelastic

博士<br>國立政治大學<br>金融研究所<br>95<br>Valuing mortgage-related securities is more complicated than valuing regular defaultable claims due to the borrower’s prepayment behavior as well as the possibility of default. In general, the methods that are applied to investigate mortgage value and termination risk can be divided into two categories: a structural-form approach and a reduced-form approach. Some researchers use a structural-form model to obtain the closed-form formulae for the mortgage value. With this method, however, it is difficult to identify the critical region of early exercise and deal w

碩士<br>臺灣大學<br>數學研究所<br>98<br>In the recent decades, literatures on credit risk measurement evolved dramatically. According to modeling techniques, they can be roughly grouped into two major categories, “structural models” and “reduced form models.” This thesis is based mainly on reduced form models and connects with structural models which include the advantages of the economic intuition to set up two models of evaluating credit risk, Jarrow04 Model and Jarrow09 Model. With the criteria of no-arbitrage pricing of bonds, pricing formulae of the two proposed reduced form models are derived for z
