We examine whether managers’ activities in striving to reach earnings targets affect their firms’ product quality. We find that firms suspected of manipulating real activities in trying to meet earnings benchmarks exhibit a higher likelihood and frequency of product recalls. Other evidence...

The 2016 Tick Size Pilot Program is an exogenous shock that incentivized fundamental investors to become more informed by acquiring fundamental firm information. Building on these studies, we examine the effect of the pilot program on earnings guidance. We find that the treatment firms...

For inequality constrained optimization problem, we show the existence of local saddle point of generalized augmented Lagrangian under weak second-order sufficient conditions which are weaker than the second-order sufficient conditions in the literature. We further discuss the existence of...

Three groups of hydrate-bearing sediment samples with/without underlying gas were prepared using a three-dimensional middle-size reactor to investigate the favorable conditions for methane recovery from hydrate reservoir with gaseous CO2. The experimental results indicated that hydrate reservoir...
