While compensation accounts for roughly 90% of K-12 instructional costs, there is little evidence of rational design in these systems. This chapter reviews the nature of teacher compensation systems in developed economies and research on their performance effects. Since these compensation schemes typically arise out of collective negotiations, this chapter also surveys the smaller literature on...

Background and Purpose: The aim of this study was to examine the effect of transforming growth factor-/31, a cytokine shown to amelioriate cardiac ischemia, in a rabbit model of thromboembolic stroke. Methods: An autologous clot embolus was introduced intracranially through the right internal carotid artery in 21 New Zealand White rabbits, with seven in each group receiving either vehicle contr...

We report here the first whole-genome sequence of a skin-associated strain of Staphylococcus hominis determined using the PacBio long-read sequencing platform. S. hominis is a major commensal of the skin microflora. This genome sequence adds to our understanding of this species and will aid studies of gene traffic between staphylococci.

We provide new evidence on business cycle fluctuations in skewed labor income risk the United States, Germany, Sweden, and France. document four results. First, all countries, skewness of individual growth is strongly procyclical, whereas its variance flat acyclical. Second, this result also holds for continuously employed, full-time workers, indicating that hours margin not main driver; additi...

We have previously shown that basic fibroblast growth factor (bFGF) is mitogenic for human bone marrow stromal cells and enhances myelopoiesis in human long-term bone marrow culture. In the present study, we examined the mechanism by which bFGF enhances granulopoiesis. We observed that bFGF significantly abrogated the inhibitory effect of transforming growth factor-j3l (TGF-PI) on granulocyte-m...

The Brain Drain: Some Evidence from European Expatriates in the United States This paper uses U.S. Census data from 1990 and 2000 to provide evidence on the labor market characteristics of European-born workers living in the US. It is found that there is a positive wage premium associated with these workers, and that the highly skilled are overrepresented compared with the source country, more ...

The existing superstar model (Rosen, 1981) does not require imperfect substitutes, and the convexity of total earnings with respect to talent is due to greater output for those with more talent. Our model explains why wages would increase at an increasing rate in talent. Imperfect substitutability between non-superstars and superstars with probabilistic production results in convexity in wage r...

This paper presents a procedure for studying industrial performance and related issues such as changes in the wage structure. This procedure combines cluster analysis and discriminant analysis as a package, and applies this package to time series data. This enables us to organize industrial data into groups with similar wage or performance histories and then to extract summary time-series showi...

I study how the relative efficiency of high- and low-skill labor varies across countries. Using microdata for countries at different stages development, document that differences in quantities wages are consistent with high-skill workers being relatively more productive rich exploit variation skill premia foreign-educated migrants to discriminate between two possible drivers this pattern: cross...
