  • On the other hand, salinity affects 7-9 % of the world’s land area (Szabolcs, 1994), and the area is increasing (Ghassemi et al., 1995). Nowadays, one of the major technological goals of the energy production is the replacement of the fossil-based fuel for biofuel, mainly due to environmental issues. Bearing that in mind, it is mandatory to investigate the effect of water deficit and salinity stress in plant species with high potential for application in large scale production of nonfossil based fuels....

  • Many policy makers and researchers believe that voluntary cost pooling of employees across small firms will make insurance affordable to these firms. This is possible because, on average, expected costs of employees at small firms are only slightly higher than large firms. We show that risk pooling across firms may not work as well as this conventional wisdom would suggest, because of large between-firm heterogeneity in employee characteristics at small firms.
