We study a dynamic moral hazard setting where the manager has private ev- idence that predicts the firm's cash flows. When performance is low, bad news disclosure is rewarded by a lower borrowing cost relative to the no-evidence case. In contrast, no disclosure is associated with higher...

Research on the statutory license for certain types of copyright-protected content has revealed an unlikely symbiosis between uncertainty and efficiency. Contrary to received wisdom, which tells us that in order to increase efficiency, we must increase stability, this Article will show that...

This paper investigates and developed credit risk models. Specifically, it focuses on the Merton model, its extensions model and the way to survey new structural approach. First, this paper describes Merton model. Second, reviews the first-passage model along with more focus on default point....

Investment-grade tranches of pools of assets by design suffer losses only rarely. The rarity of the events, or equivalently, the size of the tail, depend crucially upon the correlation between the assets. We here study the asymptotics of a model for credit assets, where correlations are due to a...

We extend the model presented in Bonollo et al. by introducing a multiscenario framework that allows for a richer and more realistic specification, including non-static (stochastic) probabilities of default and losses given default. Though more complex from a computational point of view, the...

In classical contagion models, default systems are Markovian conditionally on the observation of their stochastic environment, with interacting intensities. This necessitates that the environment evolves autonomously and is not influenced by the history of the default events. We extend the...

Under the IFRS 9 impairment model, entities must estimate the PD (Probability of Default) for all financial assets (and other elements) not measured at fair value through profit or loss. There are several methodologies for estimating this PD from market or historical information. However, in...

We develop an envelope condition method (ECM) for dynamic programming problems -- a tractable alternative to expensive conventional value function iteration. ECM has two novel features: First, to reduce the cost, ECM replaces expensive backward iteration on Bellman equation with relatively cheap...

We present a stochastic simulation model for estimating forward-looking corporate probability of default and loss given default. We formulate the model in a discrete time frame, apply capital-budgeting techniques to define the relationships that identify the default condition, and solve the...

We introduce Dirac processes, using Dirac delta functions, for short-rate-type pricing of financial derivatives. Dirac processes add spikes to the existing building blocks of diffusions and jumps. Dirac processes are Generalized Processes, which have not been used directly before because the...
