The exchange maker-taker pricing scheme affects incentives to take or make markets resulting in narrower bid-ask spreads. This study traces the effect of maker-taker pricing on stock quotations. The analyses consider distributions of quotation sizes, values implied from these sizes, and changes in these sizes and values.

In this study, supercritical carbon dioxide (scCO2) extractions of cannabinoids were conducted at four different densities (231, 590, 818, and 911 kg/m3) using ethanol (5% w/v) as a co-solvent. The chemical profiles these analysed via reverse-phase high-performance liquid chromatography (RP-HPLC). It was determined that scCO2, low density (231 kg/m3), produced an extract yield 6.1% w/v. At high...
