Option prices provide valuable information on market expectations. This paper attempts to extract market expectations, as conveyed by an implied risk-neutral probability distribution, from option prices for the dollar-euro exchange rate. Returns' volatilities are inferred from observed and...

Исследуется модель минимизации дефицита мощности в электроэнергетической системе. В модели учитываются нелинейные потери мощности в линиях электропередачи....

This article compares the properties of different non-linear Kalman filters: the well-known Unscented Kalman filter (UKF), the central difference Kalman filter (CDKF) and the new Quadratic Kalman filter (QKF). A small financial DSGE model is repeatedly estimated by several quasi-likelihood...

We propose an approximated penalized estimator (APE) that covers various statistical models and nonconvex penalties including the smoothly clipped absolute deviation (SCAD) penalty (Fan and Li, 2001) as a special case. The APE achieves the oracle property with a diverging number of parameters...

This paper evaluates monetary policy rules in a business cycle model with staggered prices and wage setting a la Calvo and asymmetric information in the credit market. Rules are compared in a utility based welfare metric, the effects of the model’s nonlinear dynamics are captured by a...

The computation of robust regression estimates often relies on minimization of a convex functional on a convex set. In this paper we discuss a general technique for a large class of convex functionals to compute the minimizers iteratively which is closely related to majorization-minimization...

This article compares properties of different non-linear Kalman filters: well-known Unscented Kalman filter (UKF), Central Difference Kalman Filter (CDKF) and unknown Quadratic Kalman filter (QKF). Small financial DSGE model is repeatedly estimated by maximum quasi-likelihood methods with...

This paper extends the framework of semi-analytical approximations to the valuation of American options by exploring the performance of competing functional forms for the value of an American option. The value function of the early exercise premium is modelled as a product of two functions, one...
