La recherche en finance d’entreprise:quel positionnement méthodologique ?

2008

(VF)Après avoir effectué, dans une première partie, un état des lieux permettant de préciser notamment la nature des questions que se posent les chercheurs en finance d’entreprise et les méthodes qu’ils emploient, la seconde partie est consacrée au positionnement de la recherche en finance d’entreprise et gouvernance sur le plan méthodologique. L’analyse fait ressortir tant l’importance de la modélisation sous ses différentes formes, qu’elle se rattache à la tradition de l’économie néoclassique ou à celle de l’économie néo-institutionnelle, que des travaux empiriques s’inscrivant dans le prolongement de cette modélisation. Sur le plan épistémologique, la recherche en finance d’entreprise se…

Structure and determinants of production in Textile-Clothing-Leather-Skins (TCLS) craft industry in Benin: a study based on investigations of the val…

2014

Lieu et date de la conférence modifiées. Prétoria 31Juillet au 2 Août 2014 (Au lieu de Kigali -Rwanda); International audience; Sustainable economic growth in Benin requires a better understand of the informalsector, which contributes to two-thirds of GDP. Particularly, craft industry and TCLSsubsector is one of informal activity sector to be handled. The objectives of this work wereto identify the structure and factors that determine the production in TCLS craft industry.This study was based on a survey carried out in February 2011 on value creationdata in craft industry of TCLS in Benin. Lack of data induced by informal activities wascircumvented using an imputation method. A Multiple Cor…

Effects of a 12‐month home‐based exercise program on functioning after hip fracture – Secondary analyses of an RCT

2022

Background Long-term functional limitations are common after hip fractures. Exercise may alleviate these negative consequences but there is no consensus on an optimal training program. The objective was to study the effects of a 12-month home-based supervised, progressive exercise program on functioning, physical performance, and physical activity. Methods Secondary analysis of a randomized controlled trial targeting patients with surgical repair of a hip fracture, aged >= 60 years, Mini-Mental State Examination (MMSE) score of >= 12. The participants were randomized into Exercise (n = 61) or Usual care (n = 60). Assessments at baseline, 3, 6, and 12 months included Lawton's Instrumental Ac…

Development and Preliminary Validation of Social Media as an Educational and Professional Tool Student Perceptions Scale (SMEPT-SPS)

2021

Although social media has an increasing presence both in university and sports settings, in the sports-management education context, no instruments (without being focused on one particular social-media platform, e.g., Facebook and Twitter) have been developed and validated that globally allow the academy to explore the perceptions of sports-management students concerning the educational and professional learning potential that these tools offer. Therefore, this research’s main objective is to develop and perform a preliminary validation of the social media as an educational and professional tool student perceptions scale (SMEPT-SPS). This study sample was composed of 90 Spanish undergraduat…

Returns to Schooling in Spain: How Reliable are Instrumental Variable Estimates?

2002

This paper studies the ordinary least–squares (OLS) and instrumental variable (IV) estimates of the returns to schooling for male workers in Spain. OLS estimates are often biased due to the endogeneity of schooling, measurement errors or omitted variables. Proper IV estimates correct this bias. The reliability of family background, natural experiments (based on changes in the education system and season of birth) and the availability of a college in the province is checked using Spanish data. The results suggest that background and college availability are valid instruments and that the IV estimates of the returns to schooling are higher than OLS estimates. These results are in line with th…

Stature and long-term labor market outcomes: Evidence using Mendelian randomization.

2017

We use the Young Finns Study (N = ∼2000) on the measured height linked to register-based long-term labor market outcomes. The data contain six age cohorts (ages 3, 6, 9, 12, 15 and 18, in 1980) with the average age of 31.7, in 2001, and with the female share of 54.7. We find that taller people earn higher earnings according to the ordinary least squares (OLS) estimation. The OLS models show that 10 cm of extra height is associated with 13% higher earnings. We use Mendelian randomization, with the genetic score as an instrumental variable (IV) for height to account for potential confounders that are related to socioeconomic background, early life conditions and parental investments, which ar…
