This paper considers the application of long memory processes to describe inflation with seasonal behaviour. We use three different long memory models taking into account the seasonal pattern in the data. Namely, the ARFIMA model with deterministic seasonality, the ARFISMA model, and the...

Long memory in variance or volatility refers to a slow hyperbolic decay in auto-correlation functions of the squared or log-squared returns. GARCH models extensively used in empirical analysis do not account for long memory in volatility. The present paper examines the issue of long memory in...

Experience from the United Kingdom and the United States suggests that expert evidence is often reshaped and repackaged by governments so that it supports existing policy rather than informing policy decisions. The Australian government based its decision to introduce FuelWatch on evidence in...

The adhesion to the European Union in January 2007 induced significant changes in the Romania’s foreign trade. In the new circumstances, the Romanian firms have to face an increased competition, but they could also fructify the opportunities of the European single market. Other changes could...

This paper considers the embedded dynamics of conditional volatility in five selected exchange rates vis-à-vis Indian Rupee. Specifically, it explores the possible asymmetric response of volatility towards good and bad news and inquires whether it is sensitive to breaks in volatility. Using a...

The Pedroni method is used to estimate the Feldstein-Horioka equation from 1960-2007 with a panel of 13 OECD countries. It is found that the Feldstein-Horioka puzzle exists in a weaker form with a much reduced saving retention coefficient. The Bretton Woods agreement in particular has weakened...

A systems GMM estimation method is used to estimate the Feldstein-Horioka equation from 1960-2007 with a panel of 12 OECD countries. It is found that the Feldstein-Horioka puzzle exists in a weaker form with a much reduced saving retention coefficient. The Bretton Woods agreement in particular...

The aim of the following work is to exploit principal econometric tecniques to test the Capital Asset Pricing Model theory in Italian equity markets. CAPM is a financial model which describes expected returns of any assets (or asset portfolio) as a function of the expected return on the market...

The purpose of this paper is to test both short- and long-run implications of the (rational) expectations hypothesis of the term structure of interest rates using Portuguese data for the interbank money market. The results support only a very weak, long-run or "asymptotic" version of the...

A contribution to the study of volatility and country risk is made in order to achieve a successful crosscountry comparison. We present a methodology for the evaluation of country risk that include endogenous detection of multiple structural breaks (also identifying its different kinds),...
