It shows that English proficiency plays an important role in immigrants’ employment and its effects on employment patterns across genders are different.

This paper presents a joint discrete-continuousmodel for activity-travel time allocation by employing the ordered probit model for departure time choice and the hazard model for travel time prediction. Genetic algorithm GA is employed for optimizing the parameters in the hazard model. The joint model is estimated using data collected in Beijing, 2005. With the developed model, departure and tra...

I test, through an analysis of order aggressiveness, whether earnings announcements of firms listed on the Italian Stock Exchange limit order book have information content. I estimate an ordered probit rel...

The empirical analysis of smoking, exercising and diet show that the mechanisms determining people’s lifestyle are complex. We argue that the economic models on the demand for health is a meaningful framework for analysing this issue, but that it needs some refinements. A suggestion for further analytical wo...

Pedestrian-involved crashes that occurred in the city of San Francisco over a six-year period, 2002–2007, were analyzed to examine various influential factors on the injury severity of pedestrian crashes. The crash data extracted from the Statewide Integrated Traffic Records System (SWITRS) include five categorical levels of injury severity in traffic crashes also in addition to detailed inform...

In recent years, a growing concern related to large truck accidents has increased owing to the level of injury severity that can be sustained and to the related potential economic impact. Current studies related to large truck–involved crashes are scarce and do not address the human factors that can greatly influence accident outcomes. This study presents an analysis of data from the fusion of ...
