Are Estimates of Non‐Standard Employment Wage Penalties Robust to Different Wage Measures? The Case of Zero‐hour Contracts in the UK
研究发现，使用不同工资衡量指标时，英国零时工合同的工资惩罚估计结果不同；基于自报小时工资率，零时工合同没有平均工资惩罚。
Evidence suggests that non‐standard jobs are associated with wage penalties. Yet, these jobs possess a range of undesirable characteristics that should generate compensating wage differentials. This evidence relies on derived wage variables, prone to measurement error likely to be correlated with employment contract. Stated‐rate hourly wage questions are not subjected to the same measurement issues. Using zero‐hour contracts in the UK, we show that there is no conditional average ZHC wage penalty once stated‐rate hourly wage measures are used. We discuss implications for policy.
