The effect of Si addition (0.2 wt%) on the precipitation evolution, hardness and electrical conductivity of Cu-2.2Ni-0.4Be alloy were investigated, and the influencing mechanism was also discussed. The results show that Si can not only form γ phase with Ni, but also promote the nucleation and...

This paper studies the effects of moral hazard on employment and wage dynamics using a continuous-time competitive search model with aggregate productivity shocks. Unobservable idiosyncratic shocks require employers to design dynamic optimal contracts to incentivize workers to exert effort. To...

We introduce sentiments under incomplete information into an otherwise standard real business cycle model. Individual firms receive signals about their idiosyncratic demand shocks which are confounded by sentiments. Sentiments coordinate optimal decisions of individuals through their extraction...

The traditional literature treat wage dispersion and firm dynamics, which are closely connected to each other, in isolation. This paper delivers a unified treatment to wage dispersion and firm-size distribution by developing a real-option-theoretic approach. The model is tractable with analytic...
