Extended local labor markets due to high speed trains : Visualization of estimations in the Swedish national travel demand forecasting tool, SAMPERS

Wider economic benefits resulting from extended geographical mobility is one argument for investments in high-speed rail. More specifically, the argument for high-speed trains in Sweden has been that they can help to further spatially extend labor market regions which in turn has a positive effect on growth and development. In this paper the aim is to cartographically visualize the potential size of the labor markets in areas that could be affected by possible future high-speed trains. The visualization is based on the forecasts of labor mobility with public transport made by the Swedish national mobility transport forecasting tool, SAMPERS, for two alternative high-speed rail scenarios. The analysis, not surprisingly, suggests that the largest impact of high-speed trains results in the area where the future high speed rail tracks are planned to be built. This expected effect on local labor market regions of high-speed trains could mean that possible regional economic development effects also are to be expected in this area. However, the results, in general, from the SAMPERS forecasts indicaterelatively small increases in local labor market potentials.

Discrimination, Peformance and Career Progression in Australian Public Sector Labor Markets

While promotion is an important mechanism for allocating labor within organizations, relatively little is known about the determinants of promotion in the highly diverse and traditionally heavily regulated Australian labor markets. This study uses unique data from the Victorian Public Sector Census 2004 to identify the extent and nature of bias in the promotion process. Specifically, we use the promotion histories of 16,675 public sector employees to investigate the existence of discrimination in promotion on the basis of gender, disability and cultural diversity. We find that some differences exist in the rate of promotion on the basis of gender, and to a lesser extent, of birthplace, but, importantly, most of these are due to differences in endowments. There are effectively no differences in promotion on the basis of disability. We find that the main driver of promotion in Victorian public sector labor markets is worker effort and performance. Compared to labor markets elsewhere, the Australian public sector is relatively free of discrimination in promotions.

Optimal Mirrleesian taxation in non-competitive labor markets

We study optimal labor income taxation in non-competitive labor markets. Firms offer screening contracts to workers who have private information about their productivity. A planner endowed with a Paretian social welfare function tries to induce allocations that maximize its objective. We provide necessary and sufficient conditions for implementation of constrained efficient allocations using tax schedules. All allocations that are implementable by a tax schedule display negative marginal tax rates for almost all workers. Not all allocations that are implementable in a competitive setting are implementable in this noncompetitive environment.
