In this paper, we revisit the relationship between educational and income inequalities in a historical perspective, using a newly developed annual dataset of average years of education in Europe. Theoretically one would expect a reduction in educational inequality should, given the positive correlation between education level and income, initially increase and then, at a later stage, reduce income inequality. Testing for such a Kuznets-type relationship between educational and income inequalities yields an unexpected result: we find the expected inverse U-curve before the 1950s, but the relationship changes into a normal U-curve afterward. We explain this observation by a change in the trend of skill premium during the second half of the twentieth century due to an increased relative demand for skills, which contradicts the usual assumption of decreasing returns to education. Due to lack of appropriate wage data, we cannot directly capture this effect. Yet, once we use an instrumental variable estimation method to filter out the effect of the omitted skill premium, the expected inverse U-curve also appears for the latter decades of the twentieth century. 相似文献

巴尔特图解在表示矽卡岩化过程中的物质成份带出带入规律时并不很清晰明确。经笔者修正后新图解的作图方法是:把矽卡岩的“标准晶胞”中的各阳离子数作为基数,计算出内外接触带相应的阳离子数之差,并以矽卡岩的各阳离子的基数作为零坐标,分别绘出阳离子的带入、带出图. 相似文献

We examine secular trends in biological well-being in the Habsburg Monarchy circa 1850–1910 on the basis of evidence on the
physical stature of recruits disaggregated at the regional level. We find that heights stagnated generally among the 1850s
birth cohorts. The secular increase in heights that lasted until the twenty-first century began among the 1860s birth cohorts.
Men born in the more developed Czech and Austria areas were as tall as many populations in Western Europe, whereas the men
born in the Polish/Ukrainian provinces were about as tall as the Mediterranean populations. There was a 3.3 cm gap between
the heights of men living in the core versus periphery of the Monarchy, which reflects a substantial gap in biological living
standards. We also consider spatial convergence of biological living standards. Heights did not converge across the different
provinces of the Monarchy at all in the 1850s, diverged in the 1860s, and began to converge subsequently. Convergence was
more rapid among those born in the 1880s than among the cohorts of the 1870s, even though the average rate of increase in
heights was greater in the 1870s than in the 1880s. The convergence was limited to the peripheral regions (Polish/Ukrainian,
Romanian, and Slovakian). No convergence was evident among the Austrian, Czech, Hungarian or Croatian areas. By the end of
the period under consideration the gap between Austrian and Polish/Ukrainian heights was reduced to 1.5 cm. The evidence on
heights is quite similar to the evidence on GDP growth insofar as it points to some positive elements but is by no means uniformly
favorable. The Monarchy was not stagnating, or about to collapse on the eve of World War I on account of economic considerations
as the Soviet Union did, but it was also not among the high-achievers of the era as the Scandinavian countries or Germany.

V.A.奥勃鲁契夫是19世纪俄国的著名地质和地貌学家。他曾几次(1880,1892—1894,1905—1906)来到中国东北、西北地区考察,著述甚多。对中国的地质和地貌学研究,特别是论述了中国黄土分布与成因方面做出了贡献。本文主要记述了他在1892—1894年来中国西北部地区考察的情况,并把要阐述他这次考察的学术成果。 相似文献
