I worked with Loren Collingwood, Will McGuire, Sarah Hampson, and Ben Gonzalez on several projects examining the impact drop boxes have on voting patterns in vote-by-mail Washington.  One study, published by Election Law Research, measures the effect large expansions in drop boxes numbers in King County have had on voter turnout in 2015 and 2016.  A second project, published by Social Science Quarterly, uses an experimental design to investigate the impact that drop box proximity has on voting turnout in Pierce County.  Visit our website for more detail. 


Using household survey data from the Luxembourg Income Study, I’ve been investigating differences among countries in the incidence of out-of-pocket health expenses.  One study examines the incidence in seven countries,  and compares citizens across the seven countries with a similar health status.  This study is published in Health Policy; you can also find a 5 minute video of the paper presentation there.  Another study compares the incidence among individuals in nine different countries with similar age and income profile; this was published in Health Services Research.  A third Project (“The Financial Burden of Out-of-Pocket Expense in the US and Canada: How Different is the US?“) compares the US with Canada. I also estimate the probability that out-of-pocket expenses in the US exceed a threshold share of income based on individuals’ health, income, and age, and estimate changes to these probabilities between 2010 and 2013. These last two studies were published in Open Medicine.

In a final project, published by the Journal of Income Distribution, I re-estimate variation among nations in the effect national policy has on income inequality and poverty after accounting for  the incidence of private health care spending.  I find that differences among countries widen after making this adjustment, one that I argue results in a better measure of the effectiveness of government policy on inequality and poverty.


Past research investigates social protection policies in the US and Europe.  One project examines changes in redistribution policies in the US over the last four decades.  Another compares variation in countries’ responses to earnings losses over the Great Recession.  Both were published in the book The Ailing Welfare State, published by Spain’s Institute for Fiscal Studies.


With assistance from a grant from the Inter-American Development Bank, a colleague and I investigated the quality of elementary school education in Paraguay, the results of which were published by the Paraguayan Ministry of Education.  My other research projects on education have been published in Education Economics, Journal of Education Finance, Review of Higher Education, and Educational Policy.
