Retail Prices of Gasoline and Asymmetric Adjustment to Wholesale Prices in Colombia
Jaime Carabalí,Luis Meneses,Alex Perez,Manuel Rodriguez 중앙대학교 경제연구소 2022 Journal of Economic Development Vol.47 No.3
This study examines the pass-through between retail and wholesale prices of gasoline in Colombia. Data from 2017 to 2019 were available on prices and characteristics of gasoline sold by service stations in the main cities of Colombia. Information on the location of the stations is also available, which is used to georeference the stations and obtain the potential number of competitors for a station. The study results show an asymmetric pass-through behavior between retail and wholesale prices. Furthermore, the potential number of competitors of the stations has a direct effect on the retail prices and an indirect effect because it alters the stations’ pass-through.

The spectroscopic investigation of new fluoreno-thiophene azomethines revealed that these compounds are fluorescent. However, they exhibit reduced fluorescence compared to native fluorene owing to competitive deactivation of the singlet excited state by nonradiative means involving both internal conversion and intersystem crossing. The absorption and emission wavelengths can be tuned and the HOMO-LUMO energy gap modulated from 2.0 to 3.2 eV by incorporating various electronic groups, number of azomethine bonds, and the fluorene-thiophene sequence. Electrochemical investigation confirmed that both oxidation and reduction occur resulting in irreversible radical ion formation.
