The present paper introduces a novel method for the construction of Socioeconomic Status (SES) indices that are specific to a target variable of interest. It is based on the Sufficient Dimension Reduction (SDR) paradigm and uses a factorized model-based approach to simultaneously deal with predictor variables of mixed nature (i.e. quantitative, binary, and ordinal), which are usual in microeconomic data. These SES indices also identify relevant predictor variables using a two-step regularized matrix factorization approach. Using data from household surveys for Argentina (Encuesta Permanente de Hogares-EPH), the proposed method is compared with other existing dimension reduction algorithms such as standard Principal Component Analysis (PCA) and its version for mixed variables, regression on the full set of variables and Least Absolute Shrinkage and Selection Operator regression (LASSO).  相似文献

The growing political polarization and the increasing use of social media have been linked to straining social ties worldwide. The 2016 presidential elections in the United States reflected this trend with reports of fear and anxiety among voters. We examine how election results can be linked to episodes of anxiety through the use of alcohol as self-medication. We analyze a daily dataset of household purchases of alcohol in the weeks following presidential elections. We find that, within 30 days from Election Day, a 10 percentage point increase in support for the losing candidate increases alcohol expenditure by 1.1%. The effect is driven by counties with a higher share of supporters of the losing candidate and is robust to controlling more flexibly for omitted variables related to alcohol consumption. The increase in alcohol consumption is present in the 2016 elections and absent in the previous three presidential elections.  相似文献
