| Analyses of ochratoxin A (OTA) in domestic and imported beers were perfomed by immunoaffinity column and high - perfomance liquid chromatography (HPLC) using a fluorescence detector. Recoveries of OTA from beer samples spiked at levels from 8.0 to 800pg/mL ranged from 81.2% to 95.0%, with coefficient of variation between 0% e 11.0%. Detection limit and quantification limit were 2.0pg/mL and 8.0pg/mL, respectively. Of the total of 26 samples produced in Brazil only 6 (23%), contained trace amounts of OTA. Of the 4 imported beers, in 2, Ireland and Germany, were detected OTA at levels of 25pg/mL and 82pg/mL, respectively. |

| The elements called heavy metals when ingested are not completely eliminated from animal bodies and are responsible for chronic and acute intoxications. Sixty-three samples of beer, produced in the states of São Paulo, Paraná, Rio de Janeiro, Rio Grande do Sul, Minas Gerais, and Pará, were analysed for lead and cadmium content by atomic absorption spectrometry with graphite furnace atomization and Zeeman correction. The concentrations of Pb and Cd of dark differed significantly from light beers, being higher in the former. No significant difference was found between the beers produced in predominantly rural areas and the ones produced in industrialized areas. The concentrations of lead and cadmium in all samples were bellow the maximum accepted by present... |

| We apply the Berry, Levinsohn and Pakes (1995) market equilibrium model (BLP) to data from 30 brands of beers sold in 12 U.S. cities over 20 quarters (1988-92) to estimate the consumers taste for beer characteristics (price, alcohol content, and calories) as well as for the cultural region of origin (USA, Anglo-European, Germanic, and countries bordering the U.S.). Consumer heterogeneity is allowed with respect to age, income and gender. Overall we end up with 7,200 beer brand observations (30x12x20) and 13,920 (58 random draws x 12 x 20) consumer observations. Empirical results indicate that indeed there is home bias with respect to European beers and somewhat less so with respect to beers from bordering countries (Mexico and Canada). Home bias is more... |
