This study investigates the impact of trading volume on selected quantiles of the EUR/PLN return distribution. Empirical results obtained with the quantile regression approach confirm that an increase in the turnover is associated with a significant increase in the dispersion of the...

In incomplete markets replication strategies may not exist and pricing of derivatives is not an easy task. This paper presents an application of Bertsimas, Kogan and Lo’s algorithm of determining an optimal-replication strategy. In the Merton model the likelihood function is a product of a...

The aim of the research is analysis of short- and long-term international relations between stock exchanges in Central and Eastern Europe. The analysis is provided in 3 stages. In the first step the order of the variables integration is examined. In the second stage short-run relationships for...

In the article dating method for the four phases of economic activity is presented. Comparison of probabilities of recession occurrence in Poland based on the Hamilton switching model and the logit model was conducted in the empirical research. The study shows the convergence of indications...

The paper discusses the problem of migration in spatial and temporal perspective. The objective is to evaluate the intensity and direction of selected economic variables impact on the volume of interregional migration flows in Poland in 2004-2010. The analysis was performed using panel gravity...

Using the monthly sampled data on LIBOR US dollar interest rates and maturities ranging from 1 to 12 months from 1995 to 2009 we provide with a number of tests of the expectations hypothesis based on a 3-variable VAR allowing for a time-varying term premium. We find some evidence against the...

In the paper, I generalize the Asymmetric Autoregressive Conditional Duration (AACD) model proposed by Bauwens and Giot (2003) with respect to the generalized gamma and the Burr distribution for an error term. I derive the log likelihood functions for the augmented models and show how to check...

The concept of causality formulated in 1969 by C.W.J. Granger is mostly popular in the econometric literature. The central assumption of the concept is the fact that the cause precedes the effect and can help in forecasting the effect. Years of application of Granger causality idea have resulted...

The purpose of the article is to model the unemployment rate in Poland in its spatial and time dimensions. The spatial lag models with the neighbourhood matrix based on the common border of poviats were used in the study. The analysis of the changes over time of the parameters in the space...

The purpose of the paper it to compare the performance of both information and prediction criteria in selecting the forecasting model on empirical data for Poland when the data generating model is unknown. The attention will especially focus on the evolution of information criteria (AIC, BIC)...
