We use the cluster variation method (CVM) to investigate the phase structure of the 3d gonihedric Ising actions deened by Savvidy and Wegner. The geometrical spin cluster boundaries in these systems serve as models for the string worldsheets of the gonihedric string embedded in Z 3. The models are interesting from the statistical mechanical point of view because they have a vanishing bare surfa...

This paper estimates the standard and tax-adjusted market risk premiums in New Zealand using historical data between 1931-2002 and a variant of the Siegel (1992) methodology. Similar to Siegel we present evidence that real bond yields in New Zealand were low over the period 1931-2002 and this may bias upwards an Ibbotsontype estimate of the market risk premium. Using an estimate for the histori...

The total cross sections of charm and beauty production at a future high–energy ep collider, THERA, are expected to increase by factors of three and five, respectively, as compared to HERA. Heavy quarks can be measured at THERA in wide ranges of transverse momenta and Q values, thereby providing a solid basis for testing the perturbative QCD calculations. The charm and beauty contributions to t...

Profit Sharing and Training We analyze the impact of profit sharing on the share of workers receiving training. An effect is plausible because: 1) profit sharing is a credible commitment by firms to reward firmspecific skills acquired by formal or informal training, 2) profit sharing may reduce turnover and increase the returns to training, 3) a common payment for the whole workforce leads to p...
