We give an account of an overlapping–generations experiment with multiple families in which voluntary transfers can take the form of support to the elderly or grants to children. Support to the old is a purely intergenerational (intra–family) transfer, whereas grants to children also involve an element of intra–generational (inter–family) redistribution through a compulsory pension system. Our data show that higher compulsory inter–family transfers lead subjects to place relatively more emphasis on support instead of grants: grants are crowded out, but support is not significantly affected. The efficiency of voluntary transfers increases, however. Furthermore, if subjects give transfers, they do not use tokens of direct reciprocity; evidence of indirect reciprocity in transfer behavior can only be obtained for the case where compulsory transfers are high.

This paper incorporates indirect reciprocal behavior in the context of bequeathing decisions into an otherwise standard OLG model. We provide conditions for the existence of a unique steady state with operative bequests. Contrary to standard OLG models, we show that taking into account such behavioral interactions allows one to rationalize both an increasing and U‐shaped pattern of the inheritance to GDP ratio over time, consistent with recent empirical evidence. Moreover, the model predicts a nonlinear (U‐shaped) relationship between the size of an unfunded social security program and the long‐run stock of per capita capital, which in turn provides a novel explanation of the inconclusive empirical findings on the relationship between social security, savings and long‐run growth. Ricardian equivalence is shown to hold in a special case of the model 相似文献

语言能力是指个体使用语言进行交际和表达思想的能力。由于被试背景、语库、语言水平、语言使用、语言态度的不同,因此一家三代人语言能力呈现不同层次。造成这一现象的主要原因是语言影响的程度和语言社会功能的层级与变化。 相似文献
