论文摘要
使用Hilda数据2001、2006、2010、2014和2017年,我们计算了这些年来所有收入分配的所有成对比较的后验概率。所认为的主要标准是洛伦兹的主导地位和一阶和二阶随机优势。使用伽马密度函数的无限混合物来估计收入分布,后验概率计算为马尔可夫链蒙特卡洛的比例,该蒙特卡洛绘制了满足定义优势标准的不平等现象。我们发现从2001年到2006年的福利得到改善,并从2006年到三年后的合格改进。无法确定2010年,2014年至2017年之间订购的证据。
Using HILDA data for the years 2001, 2006, 2010, 2014 and 2017, we compute posterior probabilities for dominance for all pairwise comparisons of income distributions in these years. The dominance criteria considered are Lorenz dominance and first and second order stochastic dominance. The income distributions are estimated using an infinite mixture of gamma density functions, with posterior probabilities computed as the proportion of Markov chain Monte Carlo draws that satisfy the inequalities that define the dominance criteria. We find welfare improvements from 2001 to 2006 and qualified improvements from 2006 to the later three years. Evidence of an ordering between 2010, 2014 and 2017 cannot be established.
