Social capital and household welfare in South Africa, 1993–98
利用南非最大省份的面板数据，研究家庭参与正式和非正式组织所衡量的社会资本与家庭福利之间的因果关系，发现1993年无影响但1998年有显著正向效应。
The aim in this study is to determine the nature of the causal relationship, if any, between ‘social capital’, as measured by household membership in formal and informal groups and household welfare in South Africa. Using a recently collected panel data set in South Africa's largest province, we estimate per capita expenditure functions including measures of social capital. After controlling for fixed effects and simultaneity, we find social capital has no effect in 1993 but a positive and significant effect in 1998.
