New CINCH working paper


A new working paper has been added to the CINCH working paper series: “Ethnic Density and Health at Birth” by Paola Bertoli, Veronica Grembi, and The Linh Bao Nguyen.

Abstract: We challenge the use of traditional measures of ethnic density— e.g., the incidence of  an  ethnic  group  on  the  resident  population  of  a  specific  area—  when  testing  the correlation between stronger ethnic networks and health at birth (i.e., birth weight). Using unique data from Italy on the main 44 ethnicities residing across almost 4,500 municipalities, we propose more insightful measures, as the distribution of immigrant associations or the incidence of ethnicities sharing the same language.  We prove that, once fixed effects for the municipality of residence and the ethnic group are included, the correlation between ethnic density and health at birth is not statistically different from zero.  However, ethnic density does channel positive effects on health at birth when a negative shock, as the 2008 Great Recession, struck the labor market.  Exploiting a quasi-randomized diffusion of the recession, we find that its average negative impact on immigrant newborns was mitigated by stronger ethnic networks.  We show that this can be explained by through sorting of the healthier and more fertile ethnic groups, which experienced also lower levels of in utero selection.

Measuring Inequality using Geo-Spatial Data

The main limitation in the study of income inequality is data availability, especially in developing countries. Our aim is to construct a measure of income inequality for all countries world-wide using geo-spatial satellite data on nighttime lights emission as well as gridded population data. We match population with the night lights data and calculate a Gini-coefficients for all countries of the world from 1992-2013. We use this data in two applications: Measuring the relationship between out-of-pocket health expenditures with inequality, find a significant and positive relationship. Similarly, we find that epidemic disasters are associated with higher inequality.

Too Sticky to Switch? Retirement and Health Plan Choices of the Elderly

The success of managed competition in health insurance largely depends on consumer switching behavior. We study whether retirement influences health plan choices of the elderly by combining evidence from a regression discontinuity design exploiting the retirement legislation in Switzerland with structural results from a discrete choice modeling approach. We find that the elderly engage in premium targeting at retirement by actively switching to less generous health plans to offset the cessation of employer contributions. Moreover, we show that the elderly are significantly more likely to switch their insurance model and deductible as a response to a premium shock triggered by retirement. Besides a strong preference for the status quo plan, our structural results indicate that retirement reduces the willingness to pay for the default. Simulated by our findings, we then explore the implications of these for the Swiss health insurance marketplace and provide suggestive evidence of consumer sorting.
