Cyclical Dimensions of Labour Mobility after EU Enlargement

This paper explores the influence of the economic cycle on labour mobility within the EU, focusing on the likely impact of the present economic crisis. To do so, we use an econometrically calibrated simulation and a case study of Ireland. We find that, in the short run, the crisis is likely to lead to a somewhat lower stock of migrants from the new member states in the EU15 than would have been the case without the crisis on account of diminished job opportunities for migrants. By contrast, in the longer run the crisis might lead to a moderate increase in migration from some of the new member states compared to what would have been the case without the crisis. The latter is driven by the observation that the crisis may have undermined the economic growth model of some of the new member states, thereby slowing down their economic catching-up process.labour mobility; economic cycle; crisis; European Union

Cyclical dimensions of labour mobility after EU Enlargement

At a time of symmetric global slowdown, migration cannot contribute as much to absorbing economic shocks as it could if the shock were asymmetric. Early evidence suggests that the crisis has led to a drop in immigration and even net return migration from some countries. This has helped the adjustment of former EU15 host countries and has exacerbated adjustment in former source countries in the new member states. In the short run, the authors believe that the stock of new member-state migrants in the EU15 will fall owing to diminished job opportunities for migrants. In the longer run, the crisis is set to increase migration from the new member states compared to what would have been the case without the crisis.

Towards large scale software based network routing simulation

Software based routing simulators suffer from large simulation host requirements and are prone to slow downs because of resource limitations, as well as context switching due to user space to kernel space requests. Furthermore, hardware based simulations do not scale with the passing of time as their available resources are set at the time of manufacture. This research aims to provide a software based, scalable solution to network simulation. It aims to achieve this by a Linux kernel-based solution, through insertion of a custom kernel module. This will reduce the number of context switches by eliminating the user space context requirement, and serve to be highly compatible with any host that can run the Linux kernel. Through careful consideration in data structure choice and software component design, this routing simulator achieved results of over 7 Gbps of throughput over multiple simulated node hops on consumer hardware. Alongside this throughput, this routing simulator also brings to light scalability and the ability to instantiate and simulate networks in excess of 1 million routing nodes within 1 GB of system memor
