The ability to predict business cycle activity is an invaluable skill for governments and policy makers alike, especially before an economy enters a downturn. We analyse causality relationships between key leading economic indicators and economic growth for three countries from 1970 to 2010. We...

Based on the two-lane traffic model proposed by Chowdhury et al., a highway traffic model with a blockage induced by an accident car is proposed, in which both symmetric lane changing rules and asymmetric lane changing rules are adopted. The fundamental diagrams and spatial-temporal profiles...

Following Henderson (1916) who developed a smoothing measure as a function of the weight system of a linear filter, Dagum and Luati (2002a) proposed a set of local statistical measures of bias, variance and mean square error which are intrinsic to the smoother and, thus, independent of the data...

We analyze the dynamics of the (non-drastic) patents which last for several periods when its owner is asymmetrically informed in relation to their users. These learn -by using the patent- its cost characteristics, and there is symmetric information among the users. In this setting, we show that...

The aim of this paper is to study the (non-drastic) patent dynamics when their users have private information with respect to the patent owner and the rival users. We found that, together with the sampling effect and the dissipation effect, an informational effect appears and, as a consequence,...
