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…

Comparison of biocides, allelopathic substances and UV-C as treatments for biofilm proliferation on heritage monuments

2018

Abstract UV-C and biocide treatments are frequently used to treat historical monuments contaminated by autotrophic biofilms. In this study, the authors compare for the first time the efficacy of these treatments against microorganisms such as cyanobacteria and algae proliferating in the Vicherey church (Vicherey, Vosges Department, France). To identify the most environmentally friendly and also efficient method, an allelopathic treatment was also tested. Colorimetric and physiological measurements of treated biofilms were thus monitored for 6 months. Fungi growing on necrotic matter from treated biofilms were sampled and sequenced. With biocides, results showed incomplete eradication of bio…

Stability of stationary solutions in models of the Calvin cycle

2017

Abstract In this paper results are obtained concerning the number of positive stationary solutions in simple models of the Calvin cycle of photosynthesis and the stability of these solutions. It is proved that there are open sets of parameters in the model of Zhu et al. (2009) for which there exist two positive stationary solutions. There are never more than two isolated positive stationary solutions but under certain explicit special conditions on the parameters there is a whole continuum of positive stationary solutions. It is also shown that in the set of parameter values for which two isolated positive stationary solutions exist there is an open subset where one of the solutions is asym…

Abstract A burgeoning body of literature suggests that poor childhood health leads to adverse health outcomes, lower educational attainment and weaker labour market outcomes in adulthood. We focus on an important but under-researched topic, which is the role played by infection-related hospitalization (IRH) in childhood and its links to labour market outcomes later in life. The participants aged 24–30 years in 2001 N = 1706 were drawn from the Young Finns Study, which includes comprehensive registry data on IRHs in childhood at ages 0–18 years. These data are linked to longitudinal registry information on labour market outcomes (2001–2012) and parental background (1980). The estimations wer…

Que disent les locutions : de, devant, et, en tant que, entre... ?

2011

Comme tous les termes d’une langue, les concepts philosophiques n’ont de sens que par leur relation à l’ensemble de la conceptualité à laquelle ils appartiennent. Mais cela signifie que la relation entre les concepts n’est pas moins essentielle que ces derniers. Et c’est cette relation que disent les éléments du langage que l’on appelle communément des particules de liaison comme de, et, après…, en dehors desquelles la parole serait pure nomination. Seulement, poser l’égale importance de ces ...

La cosmicité de l’existence : entre Patocka et Minkowski

2019

La convergence de deux dimensions des pensées de Patočka et de Minkowski en direction d’une phénoménologie non-égologique de la vie permet d’envisager la possibilité non tant d’une « comparaison » qui conduit bien souvent à juxtaposer des pensées de façon assez stérile, mais de lire Patočka à partir de Minkowski et inversement. S’ils se sont tous deux recommandés d’une phénoménologie dont le sens est assez différent, ils ont tous deux invité à reconnaître, plus, à interroger le caractère mouv...

Systemic Risk in a Structural Model of Bank Default Linkages

2018

Abstract We study a structural model of individual bank defaults across the banking sector; banks are interconnected through their exposure to a common risk factor. The paper introduces a systemic risk measure based on the default frequency in the banking sector; this measure depends non-linearly on the factor's loadings, in contrast to previous systemic risk measures that depend linearly on loadings. We estimate loadings in the U.S. banking system over the course of the last 36 years; we find that they have considerably increased over time and identify four major regimes. Our measure shows that systemic risk became critical in the last of our four regimes, covering the most recent time per…

Cross-autocorrelations in European stock returns

2016

This paper examines lead-lag relationships between monthly index returns from 18 European industries. Several interesting and clear relationships are found that call into question the efficiency of European stock markets. While the Automobiles & Parts sector lags more than half of the other sectors, the Financial Services, Technology, and Telecommunications sectors lead many others. In particular, the leadership of the Technology sector has strengthened in recent years.

Several Contemporary Economy Features, Consequences of Internet Expansion and I.C.T. Innovations in the World

2019

Abstract The Internet has reach half of the population of the planet and in the latest three years more than 700 millions users came on line from the emerging world. Most of them are coming now from the poorer population. This it may be a turning point for their economic development. This paper attempts to outline some possible future developments of the contemporary economy within the new digital transformation and development of internet firms in emerging markets, some of the pluses and minuses, some of the opportunities and threats brought by the expansion of the Internet and information and communication technologies at different levels. We will present some significant aspects about th…

Schatten über der Schwarzarbeit

2008

Die Diskussion uber Messung, Grosenordnung und Konsequenzen der Schwarzarbeit steht bereits deshalb unter einem Schatten, der den Blick dafur truben kann, weil Enste und Schneider trotz jahrelanger Befassung mit dem Thema Schwarzarbeit und Schattenwirtschaft nicht systematisch zu unterscheiden vermogen. Ihre Schatzungen fur die Dimension des Phanomens beruhen zudem generell auf wissenschaftlich nicht haltbaren Vorgehensweisen, die sie gleichwohl repetitiv anwenden. Die unterstellten Einnahmenverluste beim Staat ergeben sich im Ubrigen lediglich bei Vernachlassigung mikrookonomisch bedeutsamer Budgetrestriktionen sowie durch Auserachtlassung zwingender makrookonomischer Kreislaufzusammenhang…
