Influence of Social Institutions on Inequality in China

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.

Economic Reforms and Income Inequality in Urban China

This paper reports the results of an analysis of changes in income inequality, and in its determinants, in urban China since the economic reforms that began in 1978. The intention is to identify new characteristics of economic inequality. It first shows that income differentials acrossand in provinces widened and that their economic rankings were becoming fixed during the period from 1988 to 1995. Second, age was the major factor in inequality in 1988, while education became the important factor in 1995. Third, education significantly contributed to increasing inequality during the period. Fourth, the higher education-level groups had less within-group inequality. These changes reflect the penetration of the market mechanism into China after the reforms. However, this will be problematic without equality of opportunity.

Changes in the causes of earnings inequality in urban China from 1988 to 2002

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).

The contribution of supply and demand shifts to earnings inequality in urban China

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.

Factor decomposition of income inequality change : Japan's regional income disparity from 1955 to 1998

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.

Acoustic displacement triangle based on the individual element test

A three node, displacement based, acoustic element is developed. In order to avoid spurious rotational modes, a higher order stiffness is introduced. The higher order stiffness is developed from an incompatible strain field which computes element volume changes under nodal rotational displacements fields. The higher order strain satisfies the IET requirements, non affecting convergence. The higher order stiffness is modulated, element by element, with a factor. Thus, the displacement based formulation is capable of placing the spurious rotational modes over the range of physical compressional modes that can be accurately captured by the mesh.

Closures of positive braids and the Morton-Franks-Williams inequality

We study the Morton-Franks-Williams inequality for closures of simple braids (also known as positive permutation braids). This allows to prove, in a simple way, that the set of simple braids is an orthonormal basis for the inner product of the Hecke algebra of the braid group defined by Kálmán, who first obtained this result by using an interesting connection with Contact Topology. We also introduce a new technique to study the Homflypt polynomial for closures of positive braids, namely resolution trees whose leaves are simple braids. In terms of these simple resolution trees, we characterize closed positive braids for which the Morton-Franks-Williams inequality is strict. In particular, we determine explicitly the positive braid words on three strands whose closures have braid index three.
