Determinants of expenditures with Brazilian citizens health care: a contribution from an empirical-quantitative study in whole territory

Abstract

When you take based on the details of expenditures related to “health care” of the Household Budget Survey (HBS) 2008/2009, conducted by the IBGE, and with the overall objective of identifying the determinants of individual spending on health care conducted monthly by the Brazilian citizen initially, this study consisted of 10 study variables and 22 explanatory variables, all related to all Brazilian states and the federal district. Upon completion of this research, the evidence collected allowed us to infer that every citizen of this country incurs fixed expenses on a monthly basis with drugs around R$3.94. Furthermore, this study identified a positive trend in which every R$1.00 spent on education, the Brazilian tends to spend R$0.52 with drugs, and additionally, for each kilogram of dairy products consumed, the Brazilian tends R$2.18 to spend on medicine every month. In addition to an accuracy of about 83% relative to the screened with two model variables, the statistical tests for general validation of the model, involving the analysis of presence of multicollinearity (VIF statistics and statistical tolerance), heteroscedasticity (Pesaran-test Pesaran) and autocorrelation of residues (Dubin-Watson statistic), were all satisfactory. This, in turn, fully validated the model as explanatory variables have the “expenditures related to education” and “consumption of dairy products.”
