Price movements of stock market are not totally random. In fact, what drives the financial market and what pattern financial time series follows have long been the interest that attracts economists, mathematicians and most recently computer scientists [17]. This paper gives an idea about the...

We analyze the role of imitation and innovation in promoting technological progress in new members of European Union: the Czech Republic, Hungary, Poland and Slovakia. The two modes of technological development - innovation and imitation - are distinguished from one another by identifying the...

We analyze the role of innovation in the technological development of four new EU members: the Czech Republic, Hungary, Poland and Slovakia. For that purpose, we use a novel approach by modeling the empirical relationship between intra-industrial bilateral trade flows, which proxy the level of...

"This paper investigates the effects of labour market institutions on wage persistence among young European workers at the beginning of their careers. We use ECHP data from 1995 to 2001 for 13 EU countries and estimate a three-level random intercept probit model that allows for unobserved...

In this paper we use Portuguese data on individual (multiple) unemployment spells and apply semi-parametric duration models to investigate the effects of different types of disabilities on (re)employment probabilities. We find that disabled persons with muscular, skeletal, geriatric and...

We analyze the efficiency and productivity growth of a representative sample of Portuguese hospitals from 1997 to 2004, using an innovative approach by employing the directional distance function and the Luenberger productivity indicator. The primary advantage of our approach is that both input...

This paper compares the fitting of the normal, generalized hyperbolic, normal inverse Gaussian and Student t distributions to the daily returns of the Portuguese Stock Index PSI-20 over the period 1992-2013. We find that the distribution of the actual returns of the PSI-20 exhibits much higher...
