    Abstract: This paper looks at the effects of migration in labour market models that allow for un-employment in equilibrium. We include three different models: a competitive labour market model, a wage bargaining model and an efficiency wage model. We simulate a one-percentage point increase in the labour force due to migration. Simulation results show that effects of migration do not differ that much between different labour market models: wages decrease with 0.3% to 0.4% and the unemployment rate increases with at most 0.24 percentage points. Migration also positively affects public financing by increasing government's budget with 0.3% to 0.5%.

  2. By: Michael Creel
    Abstract: This note describes ParallelKnoppix, a bootable CD that allows econometricians with average knowledge of computers to create and begin using a high performance computing cluster for parallel computing in very little time. The computers used may be heterogeneous machines, and clusters of up to 200 nodes are supported. When the cluster is shut down, all machines are in their original state, so their temporary use in the cluster does not interfere with their normal uses. An example shows how a Monte Carlo study of a bootstrap test procedure may be done in parallel. Using a cluster of 20 nodes, the example runs approximately 20 times faster than it does on a single computer.
