A number of accelerated vehicle-retirement programs have been implemented by private companies and public agents to reduce pollution and promote environment friendly technology. Our paper examines subsidy programs for the ...

Μελέτες που αφορούν την οικονομική ανάπτυξη θεωρούν ότι η θεσμική δομή της χώρας είναι ο κυριότερος παράγων της αναπτυξιακής δυναμικής. Τούτο σημαίνει ότι δημιουργείται ένα πλαίσιο μέσα στο οποίο η συμπεριφορά των οικονομικών ...

Στο παρόν κείμενο αναπτύσσεται ένας προβληματισμός σχετικά με την κινητικότητα του ατόμου προς την επιχειρηματική προσπάΘεια. Η κινητικότητα αυτής της έκφρασης της ανθρώπινης συμπεριφοράς προσεγγίζεται μέσα από τον μεθοδολ ...

Σ' οποιονδήποτε ζει ή ταξιδεύει στην Ελλάδα δίνεται σuχνά η ευκαιρία να διαπιστώσει με τα ίδια του τα μάτια τις διαφορές στο επίπεδο ζωής μεταξύ αστικών και αγροτικών περιοχών αφ' ενός και μεταξύ τη ς Αθήνας και όλης της ...

A crucial question to anyone engaged in analysing the inflationary process in a country, is how much has the Government contributed to the generation and maintenance of the high demand pressures. The creation of demand ...

This paper relates economic theorising and policy making in a context of people's changing behaviour, which makes economy to work in a different way. As economic theory is not adapting to these changes, it produces false ...

Στο κείμενο που ακολουθεί θα εντοπιστούν οι βασικές αρχές ενός συστήματος παρακολούθησης της αγοράς κατοικίας. Μέσω από αυτό θα μπορούν να γίνονται προβλέψεις και, αφού διαπιστώνονται οι μελλοντικές ελλείψεις, θα δίνονται ...

The crucial questions which center monetary analysis are : What determines the money supply? Can the Central Bank act to influence that supply? If yes, how? These questions have generated a good deal of controversy in the ...

Value at risk is becoming increasingly popular as a management and regulatory tool. But before this acceptance goes much further, we need to assess its reliability under financial market conditions. Most VAR models deal ...

Filtered historical simulation provides the general framework to our backtests of portfolios of derivative securities held by a large sample of financial institutions. We allow for stochastic volatility and exchange rates. ...

Value at Risk (VaR) is increasingly popular as a management and regulatory tool. To further its acceptance it is necessary to assess its reliability under conditions likely to be encountered in financial markets. A logical ...

Emerging risk-management techniques use Value at Risk (VAR) to assess the market risk of a portfolio. We propose a relative simple method to estimate VAR conditionallyto reflect new information about the volatility of ...

This book covers what the authors call the “full range of major forecasting methods.” These comprise of the traditional time series methods of decomposition, exponential smoothing, simple and multiple linear regression and ...

In 1982, the Journal of Forecasting published the results of a forecasting competition organized by Spyros Makridakis (Makridakis et al., 1982). In this, the ex ante forecast errors of 21 methods were compared for forecasts ...

In this study an alternative approach for assessing securities' risk is applied. Various authors have argued that security returns are not homoskedastic but exhibit variation over time. They have observed that large changes ...

Emerging risk-management techniques use Value at Risk (VAR) to assess the market risk of a portfolio. We propose a relative simple method to estimate VAR conditionally to reflect new information about the volatility of ...

Abstract The objective of this chapter is to examine the ARCH family of volatility models and its use in risk analysis and measurement. An overview of unconditional and conditional volatility models is provided. The former ...

We propose filtering historical simulation by GARCH processes to model the future distribution of assets and swap values. Options’ price changes are computed by full reevaluation on the changing prices of underlying assets. ...

This paper we backtest the FHS VaR model on three types of portfolios invested over a period of two years. The first set of backtests consists of LIFFE financial futures and options contracts traded on LIFFE. In the second ...

VaR (value-at-risk) estimates are currently based on two main techniques: the variance-covariance approach or simulation. Statistical and computational problems affect the reliability of these techniques. We illustrate a ...
