中国制造业资本偏好水平评价

构建了包括劳动密集型产业和资本密集型产业的政府目标函数,利用2005—2012年中国省际面板数据,测算了劳动密集型产业和资本密集型产业的权重区间。研究结果表明:中国政府目标函数中资本密集产业部门的权重介于0.564~0.623之间,资本密集型产业部门的权重显著大于劳动密集型产业部门;政府更重视资本密集型产业部门的福利。     

Disaggregating and reaggregating work: Workers,management and the struggle over creating coherency and purpose in a context of work degradation

The article argues that whilst there is a growing sense of degradation and worsening conditions (disaggregation) of work in the cleaning sector in general, there are some important contradictions which require complex organisational responses. In the main, there is a growing sense of isolation in this work, yet also a growing perception of autonomy and workers having to use discretion in new and challenging ways. This article focuses on these issues and management responses to reaggregate the nature of such work, creating new forms of identity and activities intended to enhance (or address) the levels of stability and sustainability at work as well as in operational processes. This management conundrum means that they need to deal with a range of job‐related, skill‐oriented worker learning and also representation issues. These responses bring to the fore the contested nature of such forms of work and how they are changing.

LIQUIDATION IN LIMIT ORDER BOOKS WITH CONTROLLED INTENSITY

We consider a framework for solving optimal liquidation problems in limit order books. In particular, order arrivals are modeled as a point process whose intensity depends on the liquidation price. We set up a stochastic control problem in which the goal is to maximize the expected revenue from liquidating the entire position held. We solve this optimal liquidation problem for power‐law and exponential‐decay order book models explicitly and discuss several extensions. We also consider the continuous selling (or fluid) limit when the trading units are ever smaller and the intensity is ever larger. This limit provides an analytical approximation to the value function and the optimal solution. Using techniques from viscosity solutions we show that the discrete state problem and its optimal solution converge to the corresponding quantities in the continuous selling limit uniformly on compacts.
