  DOMINANCE TESTING OF TRANSFERS IN ROMANIA

  摘要：

  In this paper we compare the progressivity of different government transfers made to households in Romania. We use distribution free standard errors to examine the difference between concentration curves that may be correlated, and thereafter employ statistical tests that take into account the covariance matrix for the ordinate estimates. In addition, we estimate extended Gini coefficients for the same transfers to check their consistency with the tests of inequality dominance. The results show that almost all transfer payments in Romania are progressive, and that they have an important effect on the distribution of income. Rankings among different transfer payments are, however, not robust. In particular, sensitivity analysis using different household equivalence scales indicates that many results are not consistent across scales, and that lower size elasticities contribute to changes in ranking of Ginis and loss of statistical significance in dominance tests.

  Two 2, 3-dibenzylbutyrolactone lignans containing a secondary hydroxyl group at one of the benzylic positions, 5-hydroxyarctigenin (I) and 5-hydroxytrachelogenin (XI), were transformed to phenyltetralin lignans, α-conidendrin monomethyl ether (II) and 3-hydroxy-α-conidendrin monomethyl ether (XII), respectively, by acid treatment. The hemiacetal lignan, (1S, 2R, 3S, 3aR) 6, 7-dimethoxy-3-hydroxy-2-hydroxymethyl-1-3', 4'-dimethoxyphenyl-1, 2, 3, 4-tetrahydronaphthalene-3-carboxylic acid lactol (XV), was obtained in addition to isoolivil dimethyl ether (XIV), the normal reduction product, when 3-hydroxy-α-conidendrin dimethyl ether (XIII) was treated with lithium aluminum hydride, and a mechanism is proposed for this reaction.

  两种2,3-二苄基丁内酯木脂素（其中一种苄基位置含有次级羟基，即5-羟基白屈菜素（I）和5-羟基白屈菜素（XI））在酸处理后分别转化为苯基四氢萘木脂素、α-香树精单甲醚（II）和3-羟基-α-香树精单甲醚（XII）。当3-羟基-α-香树精二甲醚（XIII）与氢化铝锂反应时，除了得到异欧李维醇二甲醚（XIV）这一正常还原产物外，还得到了半缩醛木脂素（1S,2R,3S,3aR）6,7-二甲氧基-3-羟基-2-羟甲基-1-3',4'-二甲氧基苯基-1,2,3,4-四氢萘-3-羧酸内酯（XV），并提出了该反应的机理。
