Initial Enlargement in a Markov chain market model
2011
Enlargement of filtrations is a classical topic in the general theory of stochastic processes. This theory has been applied to stochastic finance in order to analyze models with insider information. In this paper we study initial enlargement in a Markov chain market model, introduced by Norberg. In the enlarged filtration, several things can happen: some of the jumps times can be accessible or predictable, but in the original filtration all the jumps times are totally inaccessible. But even if the jumps times change to accessible or predictable, the insider does not necessarily have arbitrage possibilities.
Portfolio performance evaluation with loss aversion
2011
In this paper we consider a loss-averse investor equipped with a specific, but still quite general, utility function motivated by behavioral finance. We show that, under certain concrete assumptions concerning the form of this utility, one can derive closed-form solutions for the investor's portfolio performance measure. We investigate the effects of loss aversion and demonstrate its important role in performance measurement. The framework presented in this paper also provides a sound theoretical foundation for all known performance measures based on partial moments of the distribution.
Childcare, height and BMI among female Polish university students, 2005
2007
The aim of this study is to consider whether socio-economic factors are related to the type of childcare and whether the type of childcare, in turn, affects adult stature and BMI. The sample includes 783 female students aged 20-24 (birth cohort of 1981-1985) from the south of Poland. Those whose parents have university education, live in a city and have no siblings attend day-care facilities more frequently than others of the same age, while those who grew up at home under their mothers' care, most frequently live in villages, come from large families and their parents have vocational education. Variables which are associated with being taller include material conditions and the type of chi…
Exposure to psychosocial work factors in 31 European countries
2012
Background Although psychosocial work factors are recognized as major occupational risk factors, little information is available regarding the prevalence of exposure to these factors and the differences in exposure between countries. Aims To explore the differences in various psychosocial work exposures between 31 European countries. Methods The study was based on a sample of 14,881 male and 14,799 female workers from the 2005 European Working Conditions Survey. Eighteen psychosocial work factors were studied: low decision latitude (skill discretion and decision authority), high psychological demands, job strain, low social support, iso-strain, physical violence, sexual harassment, bullying…
Factors associated with GPs' knowledge of their patients' socio-economic circumstances: a multilevel analysis.
2015
A paraître; International audience; Background. To determine appropriate management for individual patients, GPs are supposed to use their knowledge of the patient's socio-economic circumstances.Objective. To analyse factors associated with GPs' knowledge of these circumstances.Methods. Observational survey of GPs who were internship supervisors in the Paris metropolitan area. Each of 52 volunteer GPs completed a self-administered questionnaire about their own characteristics and randomly selected 70 patients from their patient list. Their knowledge was analysed as the agreement between the patients' and GPs' responses to questions about the patients' socio-economic characteristics in quest…
Benefits of Direct Colposcopic Vision for Optimal LLETZ Procedure: A Prospective Multicenter Study.
2015
International audience; Objective The aim of the study was to assess whether direct colposcopic ă vision (DCV) of the cervix during large loop excision of the ă transformation zone (LLETZ) is associated with a decrease in the volume ă and dimensions of specimens or affects margin status at histology. ă Materials and Methods A prospective multicenter observational study of ă 216 women who underwent LLETZ for grades 2 and 3 cervical ă intraepithelial neoplasia was conducted. The volume and dimensions ă (circumference, length, and thickness) of the surgical specimens were ă measured before fixation. Data were compared according to the use of ă colposcopy during LLETZ. The following 3 groups we…
Did the Finnish depression of the early 1990s have a silver lining? : The effect of unemployment on long-term physical activity
2022
This paper studies the impact of long-term unemployment on physical activity. We examined the effects 6 and 15 years following a severe business cycle downturn in Finland over the period 1991–1994. The study sample comprised residents of Northern Finland. The unemployed individuals were 23–26 years old during the downturn. Physical activity, measured by MET minutes and meeting WHO guidelines, was higher 15 years later among those people who experienced the longest periods of unemployment in 1991–1994. Physical activity was somewhat lower among people with relatively shorter periods of unemployment. peerReviewed

Cost and Financing of Education and its Impact on Coverage and Quality of Services and Efficiency and Equity in Sub-Saharan African Countries
2007
07052; In this chapter, we take mostly an international comparative perspective limited to Sub-Saharan African countries. First, we analyse first the macro picture and the public finance dimension, analyzing the systemic choices made in the distribution of public resources across levels and types of education. Second, we move to unit cost estimates and the factors accounting for their level in a given country and to their variation across the different countries of the region. Finally, we examine the implication of the choices made in the financial dimension upon outcomes (coverage and quality of educationl services), birnging issues of efficiency and equity into the analysis.
