Abstract:	本計劃將使用混合模型估計所得分配成長率迴歸式。經濟體按照其所得分配成長率的條件分配的近似度分為幾個群組，每群可有不同的迴歸係數。混合模型能夠找出各群之間係數差異的決定因素，而且分群決定因素與迴歸係數可同時估計。因此，本文應用混合模型探討社會資本的差異是否為所得分配變動過程(inequality growth process)差異的原因?如果答案是肯定的，經濟成長率、種族多樣程度、政府支出成長率、人口密度成長率等自變數對吉尼係數變動率的邊際效果在高、低社會資本的群組中有何不同?本文結論將有助暸解累積社會資本是否有助於減緩經濟成長和種族多樣化等因素對所得分配不均造成的負面影響。 In this project, I estimate finite mixture models in which economies are sorted into groups based on the similarity of their conditional inequality growth distributions. The relationship between inequality growth and its determinants are allowed to differ across groups. I determine whether social capital generates parameter heterogeneity in the inequality evolution process by examining whether social capital measures help to sort economies into different inequality growth processes. Namely, a finding that social capital indexes are significant class membership predictors constitute evidence that economies follow different inequality growth regimes due to differences in their level of social capital. The empirical results should shed light on how social capital alters the impacts of economic growth, ethnic diversity, government activity, and population growth on changes in income inequality.
