El objetivo es evaluar los efectos del programa Bolsa Família (PBF) en los gastos de las familias beneficiarias en: alimentos, frutas, carnes y pescados, aves y huevos, verduras, cereales y oleaginosas, harinas y pastas, tubérculos y raíces, azúcar, productos de panadería, bebidas alcohólicas, educación, higiene, salud y materiales escolares. En la estimación se utilizaron microdatos de la Encuesta de Presupuestos Familiares del Brasil 2008-2009. La metodología para calcular el efecto medio del tratamiento en los tratados fue el emparejamiento por puntaje de propensión (propensity score matching). Los resultados fueron estadísticamente significativos respecto de los gastos en: i) alimentos; ii) aves y huevos; iii) legumbres y verduras; iv) cereales, leguminosas y oleaginosas; v) harinas, féculas y pastas; vi) tubérculos y raíces; vii) azúcares y derivados, y viii) artículos escolares. Se observa que las familias beneficiarias aumentaron la adquisición de bienes prioritarios y de materiales escolares, que suponen una inversión en educación.

In the present study aimed to characterize and quantify four contaminants (ethyl carbamate, 2,3-butanedione, furfural and 5-hydroxymethylfurfural) present in alembic cachaça and industrial. Were collected forty-four samples of cachaça in the southern regions, the Midwest, southeast of Minas Gerais and São Paulo state, and subsequently subjected to physical, chemical and chromatographic analyzes. The physicochemical analyzes were performed according to the methodology described by the Ministry of Agriculture, Livestock and Supply (MAPA). The ethyl carbamate, 2,3-butanedione, furfuaral and 5 hydroxymethylfurfural were characterized and quantified by high-performance liquid chromatography (HPLC). The results of the ethyl carbamate analysis, it was found that both samples showed column cachaças outside the standards required by law, with the values 245.31 235.53 L-1 ug and none of the liquor samples alembic showed concentration greater than 210.0 ug L-1 , and the method is very sensitive to low limits of detection and quantification. In determining 2,3-butanedione, it was revealed that the column cachaças showed higher levels of contaminants when compared to cachaça alembic. In the quantification of furfural and 5-hydroxymethylfurfural was developed and validated analytical methods employed to high-performance liquid chromatography (HPLC) with DAD detector. Samples column cachaças showed higher values than the limit established by Brazilian legislation and ranged from 7.00 to 5.63 mg / 100 ml of anhydrous alcohol over the alembic cachaça.
