Improving productivity in emergency services and managing limited resources of emergency room(ER) are key challenges for health managers of oil industry. One critical and costly resource is ER personnel  and its lack can lead to long queue of patients. Thus appropriate scheduling for nurses and physicians can help ER managers to  get maximum benefit of their current human resource and reduce th...

In this paper, we study the effect of insulating and non-insulating cost allocations on internal trade in a model of incomplete information. From the perspective of firm-wide profit, the allocation scheme that results in the least amount of rationing (forgone profitable trade) is the optimal one. If one thinks of internal trade as a form of cooperation, one might expect non-insulating allocatio...

In a high tax, high minimum wage labor market like France, payroll subsidies can reduce the minimum labor cost and expand employment opportunities for the low-skilled. Effects of these subsidies go beyond the directly affected. A particular concern is that high quality jobs may be replaced with lower quality ones, which hurts the employment opportunities of highly skilled workers and is costly ...

Yemen is currently undergoing a major political transition, yet many economic challenges—including fuel subsidy reform—remain highly relevant. To inform the transition process with respect to a potential subsidy reform, we use a dynamic computable general equilibrium and microsimulation model for Yemen; we show that overall growth effects of subsidy reduction are positive in general, but povert...

1. Aquatic insects emerging from streams can provide an important energy subsidy to recipient consumers such as riparian web-building spiders. This subsidy has been hypothesized to be of little importance where the primary productivity of the recipient habitat exceeds that of the donor habitat. 2. To test this hypothesis, we manipulated emerging stream insect abundance in a productive riparian ...

To reduce equilibrium unemployment targeted hiring subsidies and profiling techniques for long-term unemployed are often recommended. To analyze the effects of these two instruments, our model combines two search methods: the public employment service and random search, jobseekers choose between an active and a passive search strategy, while labour market policy has two options available. First...
