The price of financial derivative with unilateral counterparty credit risk can be expressed as the price of an otherwise risk-free derivative minus a credit value adjustment(CVA) component that can be seen as shorting a call option, which is exercised upon default of counterparty, on MtM of the...

A class of mean reverting positive stochastic processes driven by alpha-stable distributions, 1=alpha2, are discussed. They are referred to as alpha-root processes in analogy to the square root process or the Cox-Ingersoll-Ross process derived from the Brownian motion. They are affine models in...

Looking at the valuation of a swap when funding costs and counterparty risk are neglected (i.e., when there is a unique risk free discounting curve), it is natural to ask "What is the discounting curve of a swap in the presence of funding costs, counterparty risk and/or collateralization". In...

Most popular approaches for modeling electricity prices rely at present on microeconomics rationale. They aim to study the interaction between decisions of agents in the market, and usually represent the impact of uncertainty in such decisions in a simplified way. The usual methodology of...

We study how the inclusion of growth rates of monetary aggregates or changes in stock market indices affects the stabilization performance of optimal monetary policy rules when there is uncertainty about the structure of the economy. With a simulation model of the U.S. economy we show that the...

The purpose of this paper is, through a system of software, to analyze some theoretical aggregate models. We suggest to build a disaggregated model to compare its results with these of the aggregated one. The disaggregated model uses an analogical mechanism of the individual behaviors so that a...

This paper examines the performance of prediction intervals based on bootstrap for threshold autoregressive models. We consider four bootstrap methods to account for the variability of estimates, correct the small-sample bias of autoregressive coefficients and allow for heterogeneous errors....

Introduction. The objects of investigation of this work are micro-level behaviors in stock markets. We aim at better understanding which strategies of market participants drive stock markets. The problem is that micro-level data from real stock markets are largely unobservable. We take an...

At the beginning of the transition period, the public debt in Romania was insignificant. However, during the following years, the accumulating process accelerated. Although the indebtedness degree continues to be smaller than registered levels in other European countries, more dangerous could be...
