Comparisons Between Public and Private Sector Union Wage Differentials: Does the Legal Environment Matter

对公共部门工会工资差异的估计通常是 低于私营部门工会工资的估计数 差异。 这项研究调查了这种情况在多大程度上 反映了管辖的法律的环境的差异 在每个部门的谈判。 许多州的公共部门工会 必须以比私营部门更少的法律的权利进行谈判 同行 在极端情况下，公共部门的谈判是 法律禁止的。 评估过程考虑到 在某种程度上， 这与以前的研究不同。 随机效应模型是 估计和Hausman检验，以检验相关性 状态特定误差分量和独立误差分量之间的关系 变量 1977年5月以来资料的初步分析 目前的人口调查表明，法律的环境 不是解释公共部门工会工资低的关键因素 差异。

Estimates of public sector union wage differentials are typically smaller than estimates of private sector union wage differentials. This study investigates the extent to which this reflects the differences in legal environments which govern bargaining in each sector. Public sector unions in many states must bargain with fewer legal rights than their private sector counterparts. In the extreme, public sector bargaining is prohibited by law. The estimation procedure takes into account the possible endogeneity of the bargaining law variables in a way which differs from previous studies. Random effects models are estimated and Hausman tests carried out to test for correlation between the state-specific error component and the independent variables. Preliminary analysis on data taken from the l977 May Current Population Survey indicates that the legal environment is not a key factor in explaining the small public sector union wage differentials.
