OECD countries have experienced a large increase in top wage inequality. Atkinson (2008) attributes this phenomena to the superstar theory leading to a Pareto tail in the wage distribution with a low Pareto coefficient. Do we observe a similar phenomena for academic wages? We examine wage formation in a public US university using for each academic rank a hybrid mixture formed by a lognormal distribution for regular wages and a Pareto distribution for top wages, using a Bayesian approach. The presence of superstars wages would imply a higher dispersion in the Pareto tail than in the lognormal body. We concluded that academic wages are formed in a different way than other top wages. There is an effort to propose competitive wages to some young Assistant Professors. But when climbing up the wage ladder, we found a phenomenon of wage compression which is just the contrary of a superstar phenomenon.

贝叶斯对美国学术工资的看法：从工资分散到工资压缩

经合组织国家的最高工资不平等现象大大增加。Atkinson（2008）将这种现象归因于超级巨星理论，导致工资分布中的帕累托尾巴具有较低的帕累托系数。我们是否观察到类似的学术工资现象？我们使用贝叶斯方法，对美国公立大学的工资构成进行了研究，使用每个学术级别的混合混合物，该混合混合物由正常工资的对数正态分布和最高工资的帕累托分布组成。超级巨星工资的存在将意味着帕累托尾部的分散度高于对数正态体。我们得出的结论是，学术工资的形成方式与其他最高工资不同。我们正在努力向一些年轻的助理教授提出有竞争力的工资。但是当爬上工资阶梯时，
