Spain and Switzerland: observation of the management of the Covid-19 crisis and its economic impact

Poch, Julien ; Pasche, Cyril (Dir.)

Mémoire de bachelor : Haute école de gestion de Genève, 2021 ; TDEE 455.

Under normal conditions, economies go through boom-and-bust cycles. Covid-19 highlighted the problem of uncertainty in the economy that authors such as Frank Knight have proposed, particularly the unpredictable nature of economic systems. It is in this aspect that the analysis of the phenomenon is of particular interest, with the aim of understanding the repercussions that the response, in the...

Das House Kapital

Grossmann, Volker ; Larin, Benjamin ; Steger, Thomas

(Working Papers SES ; 523)

The housing wealth-to-income ratio has been increasing in most developed economies since the 1950s. We provide a novel theory to explain this long-term pattern. We show analytically that house prices grow in the steady state if i) the housing sector is more land-intensive than the non-housing sector, or ii) technological progress in the construction sector is weaker than in the non-housing...

Magical Milk Stones?

Dasen, Véronique

In: Plutarco, entre dioses y astros. Homenaje al profesor Aurelio Pérez Jiménez de sus discípulos, colegas y amigos, 2019, no. 2, p. 1035-1048

In the Roman imperial period, a large series of so-called magical stones are carved with the image of the lion-headed snake Chnoubis. The figure is often associated with the order pesse, or pepte “digest!”, and seems to avert stomach ailment. This paper investigates other possible competences which focus on the protection of children in the form of an alternative type of milk stone,...

Inference of natural selection from ancient DNA

Dehasque, Marianne ; Ávila‐Arcos, María C. ; Díez‐del‐Molino, David ; Fumagalli, Matteo ; Guschanski, Katerina ; Lorenzen, Eline D. ; Malaspinas, Anna‐Sapfo ; Marques‐Bonet, Tomas ; Martin, Michael D. ; Murray, Gemma G. R. ; Papadopulos, Alexander S. T. ; Therkildsen, Nina Overgaard ; Wegmann, Daniel ; Dalén, Love ; Foote, Andrew D.

In: Evolution Letters, 2020, vol. 4, no. 2, p. 94–108

Evolutionary processes, including selection, can be indirectly inferred based on patterns of genomic variation among contemporary populations or species. However, this often requires unrealistic assumptions of ancestral demography and selective regimes. Sequencing ancient DNA from temporally spaced samples can inform about past selection processes, as time series data allow direct...

Ancient mitogenomics clarifies radiation of extinct Mascarene giant tortoises ( Cylindraspis spp.)

Kehlmaier, Christian ; Graciá, Eva ; Campbell, Patrick D. ; Hofmeyr, Margaretha D. ; Schweiger, Silke ; Martínez-Silvestre, Albert ; Joyce, Walter G. ; Fritz, Uwe

In: Scientific Reports, 2019, vol. 9, no. 1, p. 1-7

The five extinct giant tortoises of the genus Cylindraspis belong to the most iconic species of the enigmatic fauna of the Mascarene Islands that went largely extinct after the discovery of the islands. To resolve the phylogeny and biogeography of Cylindraspis, we analysed a data set of 45 mitogenomes that includes all lineages of extant tortoises and eight near-complete sequences of all...

Species delimitation in the East Asian species of the relict tree genus Zelkova (Ulmaceae): A complex history of diversification and admixture among species

Naciri, Yamama ; Christe, Camille ; Bétrisey, Sébastien ; Song, Yi-Gang ; Deng, Min ; Garfì, Giuseppe ; Kozlowski, Gregor

In: Molecular Phylogenetics and Evolution, 2019, vol. 134, p. 172–185

Zelkova species, trees of the elm family (Ulmaceae), are part of the Cenozoic relict flora. In western Eurasia, the genus comprises three species that are restricted to disjunct areas (Z. sicula on Sicily, Z. abelicea on Crete and Z. carpinifolia in Transcaucasia). The situation is different in East Asia, where three species (Z. serrata, Z. schneideriana and Z. sinica) have at least partly...

Cyclostratigraphy of shallow-marine carbonates – limitations and opportunities

Strasser, André

In: Stratigraphy & Timescales, 2018, vol. 3, p. 151–187

The sedimentary record of ancient shallow-marine carbonate platforms commonly displays a stacking of different facies, which reflects repetitive changes of depositional environments through time. These changes can be induced by external factors such as cyclical changes in climate and/or sea level, but also by internal factors such as lateral migration of sediment bodies and/or changes in the...

Sensitivity checks for the local average treatment effect

Huber, Martin Huber

In: Economics letters, 2014, vol. 123, no. 2, p. 220-223

The nonparametric identification of the local average treatment effect (LATE) hinges on the satisfaction of three instrumental variable assumptions: (1) Unconfounded assignment of the instrument, (2) no average direct effect of the instrument on the outcome within compliance types (exclusion restric- tion), and (3) weak monotonicity of the treatment in the instrument. While (1) often appears...
