Economic Insecurity and the Spread of Obesity in Social Networks Working Paper Series 2010-2, School of Economic Sciences, Washington State University, 2010. Also: http://www.ses.wsu.edu/PDFFiles/WorkingPapers/TSmith/wp2010-2.pdf Cohort(s): NLSY79 Publisher: School of Economic Sciences, Washington State University Keyword(s): Cohabitation; Economic Well-Being; Endogeneity; Household Composition; Obesity; Variables, Independent - Covariate; Variables, Instrumental; Weight Permission to reprint the abstract has not been received from the publisher. A number of recent studies have provided evidence suggesting that increases in body weight may spread via social networks. The mechanism(s) by which this might occur have become the subject of much speculation, but to date little direct evidence has been available. We provide evidence for one such mechanism: economic insecurity. Using a sample of working-age men from the National Longitudinal Survey of Youth, we show that cohabitation with working (but not non-working) adults appears to be protective against weight gain. We address the potential endogeneity of the independent variable by employing instrumental variables in our regression analysis. |

Why the Poor Get Fat: Weight Gain and Economic Insecurity Working Papers: 2007-16, School of Economic Sciences, Washington State University, 2007. Also: http://www.ses.wsu.edu/PDFFiles/WorkingPapers/Insecurity033007.pdf Cohort(s): NLSY79 Publisher: School of Economic Sciences, Washington State University Keyword(s): Income; Insurance, Health; Obesity; Poverty; Unemployment; Weight; Welfare Permission to reprint the abstract has not been received from the publisher. Something about being poor makes people fat. Though there are many possible explanations for the income-body weight gradient, we investigate a promising but little-studied hypothesis: that economic insecurity acts as an independent cause of weight gain. We use data on working age men from the 1979 National Longitudinal Survey of Youth (NLSY79) to identify the effect of various measures of economic insecurity on weight gain. We find in particular that over the 12-year period between 1988 and 2000, a one point (0.01) increase in the probability of becoming unemployed causes weight gain over this period to increase by about one pound, and each realized drop in annual income results in an increase of about 5.5 pounds. The mechanism also appears to work in reverse, with health insurance and government "social safety net" payments leading to smaller weight gains. |
