PurposeWe aimed to elaborate whether cycle threshold (Ct) values differ significantly between wild type SARS-CoV-2 (wtV) and certain viral variants and how strong or weak a potential significant effect might be.MethodsIn a retrospective study, we inv

Uncertainty-driven business cycles: Assessing the markup channel

Autor: Johannes Pfeifer, Benjamin Born

A growing recent literature relies on a precautionary pricing motive embedded in representative agent DSGE models with sticky prices and wages to generate negative output effects of uncertainty shocks. We assess whether this theoretical model channel

THE NEW KEYNESIAN WAGE PHILLIPS CURVE: CALVO VS. ROTEMBERG

Autor: Johannes Pfeifer, Benjamin Born

Publikováno v: Macroeconomic Dynamics. 24:1017-1041

We systematically evaluate how to translate a Calvo wage duration into an implied Rotemberg wage adjustment cost parameter in medium-scale New Keynesian DSGE models by making use of the well-known equivalence of the two setups at first order. We cons

The application of autonomous robots in agriculture is gaining increasing popularity thanks to the high impact it may have on food security, sustainability, resource use efficiency, reduction of chemical treatments, and the optimization of human effo

Strigolactones (SLs) are carotenoid‐derived phytohormones shaping plant architecture and inducing the symbiosis with endomycorrhizal fungi. In Petunia hybrida, SL transport within the plant and towards the rhizosphere is driven by the ABCG‐class
