با توجه به پیامدهای نامطلوبی که درماندگی مالی برای شرکتها، اقتصاد کشور و نهادهای پولی و مالی به همراه دارد، استفاده از روشهایی که بتواند وقوع ناتوانی مالی را پیش بینی نموده و از به هدر رفتن ثروت جلوگیری نماید از اهمیت ویژه ای برخوردار است. تاکنون مدلهای مختلفی برای پیش بینی احتمال نکول شرکتها ارائه شده است. عمده مدلهای ارزیابی ریسک اعتباری بر اطلاعات گذشته نگر متکی بوده و استفاده از مدلهایی که ...
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
Downgrade-triggered termination clause is a recent innovation in credit risk management to control counterparty credit risk. It allows one party of an over-the-counter derivative to close off its position at marked-to-market price when the other party’s credit rating downgrades to an agreed alarming level. Although the default risk is significantly reduced, the non-defaulting party may still su...
Economic theory tells us that market and credit risks are intrinsically related to each other and not separable. We describe the two main approaches to pricing credit risky instruments: the structural approach and the reduced form approach. It is argued that the standard approaches to credit risk management ± CreditMetrics, CreditRisk+ and KMV ± are of limited value when applied to portfolios o...

Let A be a finite abelian group and x an element of A. Let y be in the subgroup generated by x, so that y = nx for some positive integer n. Recall that the discrete logarithm problem is to determine n in a computationally efficient way. The computational complexity of solving this problem when the bit size of the inputs is large is the basis of many public-key encryption schemes used today. Two...
Since the paper [KM1] was released much progress has been made on the problem of bounding the analytic rank of automorphic forms on average. For example, in [KMV], a uniform bound for the square of the analytic rank of automorphic L-functions was obtained. This was used in getting a sharp numerical upper bound for average of the analytic rank. However, this improvement used only a slight varian...
abstract the present study was conducted to investigate the effect of using model essays on the development of writing proficiency of iranian pre-intermediate efl learners. to fulfill the purpose of the study, 55 pre- intermediate learners of parsa language institute were chosen by means of administering proficiency test. based on the results of the pretest, two matched groups, one as the expe...
