Comparing Cross-Country Estimates of Lorenz Curves Using a Dirichlet Distribution Across Estimators and Datasets
Chotikapanich and Griffiths (2002) introduced the Dirichlet distribution to the estimation of Lorenz curves. This distribution naturally accommodates the proportional nature of income share data and the dependence structure between the shares. Chotikapanich and Griffiths (2002) fit a family of five Lorenz curves to one year of Swedish and Brazilian income share data using unconstrained maximum likelihood and unconstrained non-linear least squares. We attempt to replicate the authors' results and extend their analyses using both constrained estimation techniques and five additional years of ...

Consumption, Wealth, and Income Inequality: A Tale of Tails
We provide evidence that the distributions of consumption, labor income, wealth, and capital income exhibit asymptotic power-law behavior with a strict ranking of upper tail inequality, in that order, from the least to the most unequal. We show analytically and quantitatively that the canonical heterogeneous-agent model cannot replicate the proper ranking and magnitudes of these four tails simultaneously. Mechanisms addressing the wealth concentration puzzle in these models through return heterogeneity lead to a mirror consumption concentration puzzle. We match the cross-sectional data on ...

The Effect of Export Market Access on Labor Market Power: Firm-level Evidence from Vietnam
We examine the impact of an export market expansion created by the US-Vietnam Bilateral Trade Agreement (BTA) on labor market competition among Vietnamese manufacturing firms. We measure distortionary wedges between equilibrium marginal revenue products of labor (MRPL) and wages nonparametrically and find that the median firm pays workers 59% of their MRPL. The BTA permanently decreases labor market distortion in manufacturing by 3.4%, mainly for domestic private firms. The median distortion is 26% higher for women than men, and the decline in distortion for women drives the overall ...
