About Gustav Kjellsson

The general theme of my research is socioeconomic differences in health and health behavior. I approach this theme from both a methodological and an empirical perspective in three broad research strands. 

The first strand of my current research has a methodological focus, studying questions on how to measure, understand, and explain health inequality. To compare the level of inequality between populations or to monitor the development over time, it is in many situations desirable to be able to summarize inequalities into one single measure. Health economists generally use versions of the concentration index. My research focus on the implicit value judgments these measures contain, and how the choice of measure may affect comparisons between populations over time or space. My interest also extends to explaining and understanding inequality. Therefore, my research also focus on methods to decompose health inequality measures into the covariates that cause the variation in health along the socioeconomic gradient.

The second strand of my current research has an empirical focus, looking at how educational institutions affect socioeconomic (health) inequality. Specifically, I use reforms in the school system as natural experiments to study the causal relationship between education at different stages in life and (health) inequality. 

The third strand of my current research focus on the nexus of information, choice and competition within primary care. Using variation from natural experiments and field experiments, I investigate questions such as how competition affect health care quality and how reducing costs of retrieving information affects patients’ choice of primary care provider. As an overarching theme, I am also interested in how these features may reduce or increase socioeconomic differences in access to health care (and health outcomes).
