The value of a statistical life (VSL) is a very controversial topic, but one which is essential to the optimization of governmental decisions. We see a great variability in the values obtained from different studies. The source of this variability needs to be understood, in order to offer public decision-makers better guidance in choosing a value and to set(More)
The views expressed here are those of the author(s) and not necessarily those of the Federal Deposit Insurance Corporation Abstract We explore the connection between the market for single-name credit default swaps (CDS) and the market for individual stock options. We find that the contemporaneous link between CDS spreads and option-implied volatilities is(More)
The relation of lexical and grammatical knowledge is at the core of many controversies in linguistics and psycholinguistics. Recent empirical findings that the two are highly correlated in early language development have further energized the theoretical debate. Behavioural genetics provides an illuminating new tool to explore this question, by addressing(More)
Recent studies do not agree on the possible relationship between medical conditions and traffic safety; most of them do not control for exposure factors. In this study, we estimate the effect of binocular vision problems on taxi drivers' distributions of crashes (frequency). Moreover, given a crash, we estimate the effect of binocular vision problems on the(More)
OBJECTIVE The U.S. and some Canadian government agencies have waived commercial license restrictions for some insulin-using diabetic drivers. However, the U.S. Federal Highway Administration is no longer giving waivers. Scientific evidence to support such regulations has been sparse. This article presents detailed analyses of crash risks for users and(More)
Recent studies do not agree on the possible relationship between medical conditions and traffic safety; most of them do not control for exposure factors. This problem has become more pertinent for scientific studies because of litigation that showed that present regulations about access to driver permits might contravene human rights legislation. In our(More)
In this research we studied the association between commercial motor vehicle drivers' medical conditions and crash severity. Some aspects of medical condition were considered. To our knowledge, no study has ever isolated this association. The severity of a crash was measured by the total number of victims (injured and dead). We estimated nonlinear(More)
This paper presents more empirical evidence on the geographical distribution of physicians. Probit procedure and data for the Province of Quebec were used. The results are consistent with the standard location theory and therefore with those of Newhouse et al. (1982a). They also show that quality of leisure, distance to central city areas, average income(More)
In this study, we address the question of patient mobility by defining three types of mobility and testing them with a Probit model. First, we have forced mobility (shortage of resources), second, physician-induced mobility (hospital affiliations) and finally, the mobility chosen by patients. We isolate explanatory variables for observed patient mobility(More)
