There are a number of studies which consider the relation between military spending and economic growth using Granger causality techniques rather than a well-defined economic model. Some have used samples of groups of countries, finding no consistent results. Others have focused on case studies...

A recent paper by Barkoulas et al. (Applied Financial Economics, 10, 177-84, 2000), examining long memory of returns in the Athens Stock Exchange (ASE, hereafter), finds evidence in favour of long memory. In this paper, long memory of returns in the ASE along with volatility are examined, using...

This paper examines hedging in Greek stock index futures market. The focus is on various techniques to estimate constant or time-varying hedge ratios. For both available stock index futures contracts of the Athens Derivatives Exchange (ADEX), a variety of econometric models are employed to...

A number of studies consider the relation between military spending and economic growth using Granger causality techniques. Some studies have used samples of groups of countries, finding no consistent results. Other studies have focused on individual countries, which permits greater knowledge of...

The finite-sample size properties of smooth transition unit root tests are examined when applied to unit root processes subject to breaks in either level or drift. In contrast to the weighted symmetric and recursively mean-adjusted unit root tests which have been shown to be robust in these...

A class of smooth transition momentum-threshold autoregressive (ST-MTAR) tests is proposed to allow testing of the unit root hypothesis against an alternative of asymmetric adjustment about a smooth nonlinear trend. Monte-Carlo simulation is employed to derive finite-sample critical values for...
