This study analyses the impact of changes in social institutions, i.e. in the informal and formal social security system, on income inequality in China. This study uses an inequality decomposition analysis approach comparing household survey data for 1988 with 1995.Three main results emerge from the analysis: first, it findsthat the family based social security is losing its importance mainly through the changes in employment pattern in a household. This change contributes to rising income inequality. Second, thestudy shows that the introduction of new formal social security system helped to equalise the distribution of retired household members' income in urban areas in 1995. Third, however, these changes have only benefited a restricted number of persons. Benefits for rural migrants are low and most of the rural population has still no access to the new system.

This paper analyzes the causes of earnings inequality in urban China from 1988 to 2002. Earnings inequality in urban China continuously increased, even when adjusting for regional price differences. This paper reveals how the causes of earnings inequality changed between the periods 1988-1995 and 1995-2002 by reflecting labor-related institutional reform in China. Contrary to the situation from 1988 to 1995, between 1995 and 2002, employment status became the largest disequalizer, and the decline of inter-provincial inequality contributed to a reduction in entire earnings inequality. Individual ability, represented by education and occupation, received much greater rewards. Throughout the period from 1988 to 2002, a large part of the explained inequality increase was due to change in price (valuation of each individual's attributes) and not due to change in quantity (composition of individual attributes).

This paper examines the degree to which supply and demand shift across skill groups contributed to the earnings inequality increase in urban China from 1988 to 2002. Product demand shift contributed to an equalizing of earnings distribution in urban China from 1988 to 1995 by increasing the relative product for the low educated. However, it contributed to enlarging inequality from 1995 to 2002 by increasing the relative demand for the highly educated. Relative demand was continuously higher for workers in the coastal region and contributed to a raising of interregional inequality. Supply shift contributed essentially nothing or contributed only slightly to a reduction in inequality. Remaining factors, the largest disequalizer, may contain skill-biased technological and institutional changes, and unobserved supply shift effects due to increasing numbers of migrant workers.

El artículo examina la evolución de la estructura salarial de los hombres en España en el período 2002-2010 sobre la base de los microdatos de la Encuesta de Estructura Salarial y de la metodología econométrica de descomposición desarrollada por Fortin, Lemieux y Firpo (2011). Se constata que mientras que los salarios reales crecieron moderadamente a lo largo de todo el período, con independencia del ciclo económico, la desigualdad salarial presentó, por el contrario, una evolución contracíclica. Se observan también cambios notables en los determinantes de la evolución de la estructura salarial, ya que mientras que en el período expansivo anterior a la crisis tuvieron un papel protagonista los cambios en los rendimientos salariales, con posterioridad se observan también efectos significativos asociados a las modificaciones en la composición del empleo.

We propose a method for the decomposition of inequality changes based on panel data regression. The method is an efficient way to quantify the contributions of variables to changes of the Theil T index while satisfying the property of uniform addition. We illustrate the method using prefectural data from Japan for the period 1955 to 1998. Japan experienced a diminishing of regional income disparity during the years of high economic growth from 1955 to 1973. After estimating production functions using panel data for prefectures in Japan, we apply the new decomposition approach to identify each production factor’s contributions to the changes of per capita income inequality among prefectures. The decomposition results show that total factor productivity (residual) growth, population change (migration), and public capital stock growth contributed to the diminishing of per capita income disparity.

The paper utilises the Juhn Murphy and Pierce (1991) decomposition to shed light on the pattern of slow male-female wage convergance in Australia over the 1980s. The analysis allows one to distinguish between the role of wage structure and genderspecific effects. The central question addressed is whether rising wage inequality counteracted the forces of increased female investment in labour market skills, i.e. education and experience. The conclusion is that in contrast to the US and the UK, Australian women do not appear to have been swimming against a tide of adverse wage structure changes.

This paper investigates determinants of regional income disparity in rural Vietnam, with special emphasis placed on the roles of human capital and land. We apply a decomposition method, suggested by Oaxaca and Blinder. We found that returns to assets rather than endowments, especially those of human capital, are one of the leading factors to account for income differences across regions. We also found that substantial improvements of returns to human capital in the Red River delta region are a driving force to catch up with Mekong River delta region. Unexpectedly, differences in land endowment do not strongly correlate with regional income disparity because better access to land in a region was partially offset by lower returns.

jmpierce computes the decomposition of differences between two outcome distributions introduced by Juhn, Murphy and Pierce (1993). Examples are the decomposition of changes in the income distribution over time, the decomposition of male-female wage differentials, or the decomposition of wage inequality differences between countries. This routine was previously circulated as jmp.

The morphological and chemical changes occurring during the thermal decomposition of weddelite, CaC2O4·2H2O, have been followed in real time in a heating stage attached to an Environmental Scanning Electron Microscope operating at a pressure of 2 Torr, with a heating rate of 10 °C/min and an equilibration time of approximately 10 min. The dehydration step around 120 °C and the loss of CO around 425 °C do not involve changes in morphology, but changes in the composition were observed. The final reaction of CaCO3 to CaO while evolving CO2 around 600 °C involved the formation of chains of very small oxide particles pseudomorphic to the original oxalate crystals. The change in chemical composition could only be observed after cooling the sample to 350 °C because of the effects of thermal radiation.

The thermal stability and thermal decomposition pathways for synthetic iowaite have been determined using thermogravimetry in conjunction with evolved gas mass spectrometry. Chemical analysis showed the formula of the synthesised iowaite to be Mg6.27Fe1.73(Cl)1.07(OH)16(CO3)0.336.1H2O and X-ray diffraction confirms the layered structure. Dehydration of the iowaite occurred at 35 and 79°C. Dehydroxylation occurred at 254 and 291°C. Both steps were associated with the loss of CO2. Hydrogen chloride gas was evolved in two steps at 368 and 434°C. The products of the thermal decomposition were MgO and a spinel MgFe2O4. Experimentally it was found to be difficult to eliminate CO2 from inclusion in the interlayer during the synthesis of the iowaite compound and in this way the synthesised iowaite resembled the natural mineral.
