ABSTRACT Two competing models, gravitational instability-driven transport and stellar feedback, have been proposed to interpret the high velocity dispersions observed in high-redshift galaxies. We study major mechanisms drive turbulence star-forming galaxies using a sample of from xCOLD GASS survey, selected based on their star formation rate (SFR) gas fraction be regime that can best distingui...

This paper studies the impact of competition on the degree of inefficiency in lemons markets. More precisely, we characterize the second-best mechanism (i.e., the optimal mechanism with private information) in a stylized lemons market with finite numbers of buyers and sellers. We then study the relationship between the degree of efficiency of the second-best mechanism and market competitiveness...
