Fixed coecients State-Space and VARMAX models are equivalent, meaning that they are able to represent the same linear dynamics, being indistinguishable in terms of overall fit. However, each representation can be specifically adequate for certain uses, so it is relevant to be able to choose...

Рассмотрена задача построения канонических форм нелинейных систем, описываемых непрерывными и дискретными динамическими моделями.

There are a number of econometrics tools to deal with the different types of situations in which cointegration can appear: I(1), I(2), seasonal, polyno- mial, etc. There are also different kinds of Vector Error Correction models related to these situations. The authors propose a unified...

This paper introduces heterogeneity of cross-technologies interactions into the double-differentiated R&D-based endogenous growth model. In this model new technologies appear continuously and older are outdated generating structural change. All technologies may interact with each other through...

The article develops a systematic method of calculation of an approximate price for a wide range of securities with the help of instruments of spectral analysis, singular and regular wave theory. Price of options depend on stochastic volatility, which depends on a method. Finding the price is...
