Funding Liquidity and Market Liquidity

Recent empirical studies have shown an increasing co-movement between fund and market liquidity, which is driven by common factors such as monetary shocks. Modeling this comovement becomes desirable to evaluate policies relating to liquidity and financial instability. This paper establishes a monetary model with capital to explain the dynamic interactions between funding and market liquidity in...

Asset Liquidity and Stock Liquidity

We study the relation between the liquidity of the firm’s assets and the liquidity of financial claims on the assets, thereby linking corporate finance decisions to stock liquidity. Our model highlights an ambiguous relationship. While greater asset liquidity reduces uncertainty regarding valuation of assets-in-place, it increases future investments and the associated uncertainty. The model sho...

Lift force in bubbly suspensions

Closure relations are presented for the lift coe.cient for ordered arrays of 2-D and 3-D bubbles at various bubble volume fractions. These were determined via lattice Boltzmann simulations of bubble rise in periodic boxes, where the bubbles were also subjected to shear. The single-bubble lift coe.cient, determined by low-shear computational experiments, varies in a systematic manner with the as...
