Fair Pension Policies with Occupation-Specific Ageing
研究了在多期世代交叠模型中，考虑不同职业的发病率和死亡率差异时，如何设计公平的公共养老金制度，并以德国为例发现最优政策可提高蓝领工人的福利。
Abstract We study the optimal design of a fair public pension system in a multi-period overlapping generations model with occupation-specific morbidity and mortality that depends on the retirement age. The fairness constraint acts as institutional device ensuring that lifetime returns to contributions are equal across occupational groups. We consider group-specific replacement rates and a calculatory interest rate for early contributions as policy instruments. Calibrating the model to Germany, we find that the transition to optimal fair pension policies may induce early retirement of blue-collar workers and significantly raises their lifetime pension benefits and welfare. Aggregate welfare increases in all fair pension scenarios.
