The idea that certain economic variables are roughly constant in the long-run is an old one. Kaldor described them as stylized facts, whereas Klein and Kosobud labelled them great ratios. While such ratios are widely adopted in theoretical models in economics as conditions for balanced growth,...

The U.S. prewar output series exhibit smaller shock-persistence than postwar-series. Some studies suggest that this may be due to linear interpolation used to generate missing prewar data. Monte Carlo simulations that support this view generate large standard-errors, making such inference...

The aim of this work is to establish an interesting connection between the behavior of economic agents by means of complex systems approach and the long memory features that generally occur in a wide set of time series found in economic/financial problems. It is shown that heterogeneity between...

The aim of this paper is to find out the forecasting model that is the one, which gives the best output of forecasting. So that policy makers can be benefited from this research. Thus, this research will also evaluate the performance of ARMA, and Box-Jenkins (ARIMA) forecasting models for KIBOR...

This program helps to identification and aytomatic forecasting with ARMA models for forecasters and analysts.This program is compatible with EViews 3,3.1,4,4.1. For running it in EViews 5 and 5.1 simply check the box Version 4 compatible variable substitution

This paper deals with some technical fundamentals necessary to understand, at least heuristically, stochastic volatility processes and associated measures. I present the stylised facts of a financial dataset in order to explore its fundamental statistical properties, which are then used to...

Social science has come under a firestorm of criticism following the discovery that many findings cannot be replicated. This paper argues that increasing the use of out-of-sample tests would improve the reliability of findings in all fields, including “complex” fields such as macroeconomics....

The current paper experiments with the conception and analytical model of principle components. The analysis utilizes data of Sudan to test the model fitness and data suitability. All the country's economic sectors are used in the analysis which also integrates high, medium and low income strata...

In this paper, we review the recent econometric methods related to unit root tests. The central idea is the interaction between structural breaks and unit roots. We consider the standard Dickey-Fuller test and its modifications that allow under the alternative hypothesis one or multiple...
