Several tests for nonlinear causality are available on the literature. In this paper we investigate the effects of temporal aggregation and systematic sampling using some well known linear and nonlinear Granger causality tests. The conducted Monte Carlo simulation experiments and the empirical...

One of the most enduring debates in economics is whether financial development causes in a linear or nonlinear manner, economic growth or whether it is a consequence of increased economic activity. Little research into this question has been done for the case of Greece especially in a nonlinear...

In this paper, we investigate the implications of measurement errors in the daily published stock prices on the creation and management of efficient portfolios. Using stochastic simulation techniques and the Markowitz Mean Variance approach in the creation of the weights of the various stocks of...

This short paper examines the nonlinear interaction between mutual fund flows and stock returns in Greece. We investigate the possibility of a nonlinear causality mechanism through which mutual funds flows may affect stock returns and vice versa. The statistical evidence derived from linear and...

This short paper examines the nonlinear interaction between mutual fund flows and stock returns in Greece. We investigate the possibility of a nonlinear causality mechanism through which mutual funds flows may affect stock returns and vice versa. The statistical evidence derived from linear and...

This short paper demonstrates that the use of temporally aggregated data may affect the power and the size of the well known the Ramsey's (1969) RESET test. This test is widely used for testing the functional specification of a model. Using Empirical data and Monte Carlo techniques we found that...

This paper examines the existence of a linear or nonlinear interaction between the Advance/Decline ratio index and the returns of the Athens General Index. We investigate the possibility of a nonlinear causality mechanism through which the Advance/Decline ratio index (the ratio of the number of...

In this paper, we examine the effects of data collection frequency on the computation of the Consumer Price Index (CPI). Using stochastic simulation techniques, we conclude that the frequency of data collection has a considerable effect on CPI values. Our findings confirm the need for high...

This paper considers the dynamics of the OECD macroeconomic forecasts for Greece. A Geometric Distributed Lags model is used to study the dynamic responses between the actual data and the forecasts supplied by OECD the last 15 years.
