I analyze the relationship between duration of the pension benefit spell and pension benefit claims from the German public pension system, with a special emphasis on differential results with respect to health. This relationship is crucial for a potential structural pattern of redistribution between different income and health groups, induced by the public pension system. Evidence for such redistribution from poor to rich is present for most of the specifications in my analysis. The most adequate specification is partially linear, does therefore not impose any parametrical restrictions between duration and benefit claims, and allows for potential endogeneity. The relationship I extract is clearly positive. I also find that redistribution from low-income individuals to individuals with high income is more pronounced the worse the health status is, despite longer benefit spells for pensioners in ill-health.
我分析了德国公共养老金制度中养老金福利期的时长与养老金福利申领之间的关系，特别关注了健康方面的差异结果。这种关系对于公共养老金制度引发的不同收入和健康群体之间潜在的再分配结构模式至关重要。在我的分析中，大多数设定都存在从贫困群体向富裕群体这种再分配的证据。最合适的设定是部分线性的，因此在时长和福利申领之间不施加任何参数限制，并考虑到潜在的内生性。我得出的关系显然是正相关的。我还发现，尽管健康状况不佳的养老金领取者福利期更长，但健康状况越差，从低收入个体到高收入个体的再分配就越明显。
