Sustainable growth and financial markets in a natural resource-rich countryJournal articleEmma Hooper, Structural Change and Economic Dynamics, Volume 51, pp. 341-348, 2019

This paper studies the optimal growth path of a natural resource-rich country, which can borrow from international financial markets. I explore to what extent international borrowing can overcome resource scarcity in a small open economy, in order to have sustainable growth. First, a benchmark model with a constant interest rate and technical progress is set up to see if the economy's growth can be sustainable in the long run. Secondly, the case of a debt elastic interest rate is analysed. The main finding of this paper is that borrowing on international capital markets does not permit sustainable growth for a country with exhaustible natural resources, when the interest rate is constant. Nevertheless, when the interest rate is endogenized, the consumption growth rate can be positive before declining.

Growth and agglomeration in the heterogeneous space: a generalized AK approachJournal articleRaouf Boucekkine, Giorgio Fabbri, Salvatore Federico et Fausto Gozzi, Journal of Economic Geography, Volume 19, Issue 6, pp. 1287-1318, 2019

We provide an optimal growth spatio-temporal setting with capital accumulation and diffusion across space to study the link between economic growth triggered by capital spatio-temporal dynamics and agglomeration across space. The technology is AK, K being broad capital. The social welfare function is Benthamite. In sharp contrast to the related literature, which considers homogeneous space, we derive optimal location outcomes for any given space distributions for technology and population. Both the transitional spatio-temporal dynamics and the asymptotic spatial distributions are computed in closed form. Concerning the latter, we find, among other results, that: (i) due to inequality aversion, the consumption per capital distribution is much flatter than the distribution of capital per capita; (ii) endogenous spillovers inherent in capital spatio-temporal dynamics occur as capital distribution is much less concentrated than the (pre-specified) technological distribution; (iii) the distance to the center (or to the core) is an essential determinant of the shapes of the asymptotic distributions, that is relative location matters.

Popper à Vienne. L’éducatrice et son témoinBook chapterGilles Campagnolo, In: Apprentissage et découverte : Ecrits de jeunesse (Vienne, 1925-1935), 2019-11, pp. 221-302, Rue d'Ulm, 2019
Apprentissage et découverte : Ecrits de jeunesse (Vienne, 1925-1935)BookKarl Popper, « Versions françaises », 2019-11, 320 pages, Rue d'Ulm, 2019

Après la publication du Soi et son cerveau (Rue d’Ulm, oct. 2018), ce volume vient clore la publication des œuvres de Popper en langue française (à l’exception de textes datés consacrés quasi exclusivement à la physique quantique). Les écrits de jeunesse montrent la genèse de l’œuvre poppérienne dans une Vienne éducatrice et matrice de savoirs neufs (réforme scolaire, néopsychologie, Cercle de Vienne) au sein d’un milieu cosmopolite progressiste, et l’environnement d’un penseur enthousiaste dans ses premières réalisations. Ils traitent aussi bien de la relation élève-enseignant que du processus de mémorisation, de l’idée de patrie que de l’« expérience vécue de la règle ».

The positive effect of workplace accommodations on employment five years after a cancer diagnosisJournal articleCaroline Alleaume, Alain Paraponaris, Marc Karim Bendiane, Patrick Peretti-Watel et Anne-Deborah Bouhnik, European Journal of Public Health, Volume 29, Issue Supplement_4, 2019

Background:
Each year, almost 400,000 new individuals are diagnosed with cancer in France and nearly half of them are in the working age. The disease was found to have a negative impact on professional life, especially for the most vulnerable cancer survivors. Literature reviews have pointed out the lack of studies focusing on the evaluation of interventions. In France, workstation layouts are recommended by the French law, but not mandatory to facilitate return to work. The aim of this study was to explore the effect of having a workstation layout after a cancer diagnosis on maintenance in employment five years after diagnosis.

Methods:
We used the French VICAN survey carried out in 2015/2016 on living conditions five years after a cancer diagnosis. Using propensity score matching, we matched two subsamples (with and without workstation layout) to investigate the effect of workstation layout taking into account the characteristics associated with the access to these arrangements.

Results:
Among the 1,514 individuals aged between 18 and 54 at diagnosis and employed in a salaried job at this time, three in five (61.2%) had a workstation layout within the five years following the diagnosis: 35.5% had a position type layout, 41.5% had a schedule layout, and 49.2% had a working time layout. Among those who had a workstation layout, 89.7% were still in employment five years after diagnosis against only 77.8% of those who did not so (p.value<0,001). After matching, having a workstation layout increased maintenance in employment from 77.8% to 95.0% (Average workstation layout effect on the treated of 0.172, 95% CI = [0.114; 0.229]).

Conclusions:
Having a workstation layout after a cancer diagnosis strongly increases maintenance in employment of five years cancer survivors. More research is needed to better understand the differences in access to these arrangements and the related
selection effect.

Key messages:
Workstation layout increases maintenance in employment of survivors five years after a cancer diagnosis. Therefore, it should be used more systematically to facilitate work with a chronic disease. Having a workstation layout may constitute a disadvantageous selection bias for more vulnerable workers. It can also lead to discrimination feelings.

An analytical framework for retailer price and advertising decisions for products with temperature-sensitive demandJournal articleRégis Chenavaz, Octavio Escobar et Xavier Rousset, Applied Economics, Volume 51, Issue 52, pp. 5683-5693, 2019

The demand for weather-sensitive products, such as beverages, ice creams, or chocolate varies with changes in temperature. Yet, retailers lack a framework to adapt the marketing mix elements, such as price and advertising, in line with such changes. We provide a theoretical framework to fill this gap by developing an analytical model to derive the optimal marketing mix when product demand depends on temperature. The model prescribes how price and advertising for different demand characteristics should be set following a temperature change. Integrating the temperature element in the marketing mix offers an original profit-enhancing strategy.

Predicting musculoskeletal disorders risk using tree-based ensemble methodsJournal articleAlain Paraponaris, A. Ba, Ewen Gallic, Q. Liance et Pierre Michel, European Journal of Public Health, Volume 29, Issue Supplement_4, 2019

Background:
Musculoskeletal disorders (MSD) can cause short-term disorders and permanent disabilities which may all result in serious limitations in ac

« Dis-moi ce que tu penses de la propriété intellectuelle, je te dirai qui tu es »Journal articleRémy Guichardaz, Thomas Coudert, Herrade Igersheim, Mathieu Lefebvre et Julien Pénin, Revue Économique, Volume 70, Issue 6, pp. 1213-1226, 2019

L’objet de cet article est d’analyser de manière expérimentale les liens supposés entre les préférences sociales des individus et la manière dont ils conçoivent la propriété intellectuelle, en opposant en particulier les approches utilitaristes et déontologiques. Pour ce faire, nous avons mis en place un protocole expérimental original à l’interface de deux courants de littérature : l’un, bien établi, traitant des préférences sociales ; l’autre, naissant, tentant de capter les différentes justifications de l’existence de la propriété intellectuelle. Notre expérience aboutit à deux enseignements majeurs : 1) les sujets utilitaristes semblent changer de conception de la justice sociale dès lors que la question de la propriété intellectuelle est posée ; 2) les sujets rawlsiens sont en parfaite cohérence avec l’approche déontologique de la propriété intellectuelle, donnant la priorité aux droits des auteurs et des inventeurs, tout en minimisant les inégalités pouvant en résulter en optant, par exemple, en faveur d’une durée courte de propriété intellectuelle.

Trade Policy and Market Power: Firm-Level EvidenceJournal articleAlan Asprilla, Nicolas Berman, Olivier Cadot et Mélise Jaud, International Economic Review, Volume 60, Issue 4, pp. 1647-1673, 2019

This article identifies the effect of trade policy on market power through new data and a new identification strategy. We identify market power by observing how exporting firms price discriminate across markets following variations in bilateral exchange rates. Pricing-to-market is prevalent in all countries in our sample, even among small firms, although it is increasing in firm size. More importantly, we find that the effect of nontariff measures (NTMs) is not isomorphic to that of tariffs. Whereas tariffs reduce the market power of foreign firms through rent-shifting effects, NTMs reinforce the market power of nonexiting firms, domestic and foreign alike.
