Enzymatic turnovers of single cholesterol oxidase molecules were observed in real time by monitoring the emission from the enzyme's fluorescent active site, flavin adenine dinucleotide (FAD). Statistical analyses of single-molecule trajectories revealed a significant and slow fluctuation in the rate of cholesterol oxidation by FAD. The static disorder and dynamic disorder of reaction rates, whi...

Recent fluorescence spectroscopy measurements of single-enzyme kinetics have shown that enzymatic turnovers form a renewal stochastic process in which the inverse of the mean waiting time between turnovers follows the Michaelis-Menten equation. We study enzyme kinetics at physiologically relevant mesoscopic concentrations using a master equation. From the exact solution of the master equation w...

Almost all real assets trade in decentralized markets, where trading frictions could inhibit the efficiency of asset allocations and depress asset prices. In this paper, I investigate how trading frictions vary as asset markets get thicker, and what implications market thickness has for asset allocations and prices. Intuitively, it is easier to sell assets that have a thicker market. As a resul...

We argue that mutual fund managers should trade actively only when the market presents opportunities to pick stocks with positive alpha. In this paper, we propose stock-selection opportunity measures and show a significant portion of funds time their active trading, i.e., they more opportunities. timers outperform negative by about 82 bps in annualized four-factor alpha over subsequent six-mont...

Prior research has indicated that employee turnover is detrimental to both individuals and organisations. Because a turnover intention in the workplace is detrimental, several factors have been suggested to better understand the reasons why employees may decide to leave their organisations. Some of the organizational-related factors that have been considered by previous research include perceiv...

We investigate the trading and yield effects of covenant-lite (cov-lite) high-yield bond contracts, which have a restricted (lite) set covenants. The excluded covenants often are those that use accounting performance measures. Although much research has focused on potential benefits as basis for debt contracting, little is known about settings where it may be optimal to exclude statistics from ...

Decarbonisation implies conversion to electrification with a subsequent increase in electricity consumption. The EU Emission Trading System (EU ETS) compensates firms for the higher costs. We exploit sectoral and country differences regulation unique dataset on beneficiaries evaluate impact of ETS indirect cost compensation performance aided firms. Receiving costs does not have statistically si...
