RURAL NONFARM EMPLOYMENT UNDER TRADE REFORM EVIDENCE FROM VIETNAM, 1993-2002

Vietnam’s rural economy has substantially diversified over the past two decades. The rural nonfarm sector has grown rapidly and became an important source of employment and income for rural households. This growing nonfarm employment was associated with radical changes in the trade policy reform that has put the country to the top two or three performers in the developing world. This paper examines the potential effect of the trade policy reform on nonfarm employment in rural Vietnam during the period 1993-2002. It proposes two trade openness indices that allow changes in the trade policy at the macro level to be transmitted to rural households. The results reveal that the trade policy reform does have a material impact on rural nonfarm employment. While a more liberalized agricultural sector encourages nonfarm diversification, a lower protection level in the nonfarm sector discourages individual participation in nonfarm income-generating activities.Trade liberalization, trade policy reform, rural nonfarm employment, Vietnam

The Gender Pay Gap In Vietnam, 1993-2002: A Quantile Regression Approach

This paper uses mean and quantile regression analysis to investigate the gender pay gap for the wage employed in Vietnam over the period 1993 to 2002. It finds that the Doi moi reforms have been associated with a sharp reduction in gender wage disparities for the wage employed. The average gender pay gap in this sector halved between 1993 and 2002 with most of the contraction evident by 1998. There has also been a contraction in the gender pay at most selected points of the conditional wage distribution with the observed effect most pronounced at the top end of the distribution. However, the decomposition analysis suggests that the treatment effect is relatively stable across the conditional wage distribution and little evidence of a ?glassceiling? is detected for Vietnamese women in the wage employment sector in any of the years examined.Gender pay gap, Quantile regression, Vietnam

Theory of ferromagnetism in vanadium-oxide based perovskites

The conditions under which ferromagnetism may occur in transition metal oxides with partially filled $t_{2g}$ shells such as vanadium-based perovskites are studied using a combination of density functional and single-site dynamical mean field methods. For reasonable values of the correlation strength, rotations of the VO$_6$ octahedra play an important role in enabling ferromagnetism, with ferromagnetism typically occurring for rotations larger than a nonzero critical value. Ferromagnetism is suppressed near the Mott insulating phase but the phase boundary is otherwise only weakly dependent on carrier concentration. Design rules are suggested for new oxide systems exhibiting ferromagnetism.Comment: 13 pages, 11 figure

Ethnic Wage Inequality in Vietnam: Empirical Evidence from 2002

This paper complements earlier studies on ethnic minority underdevelopment in Vietnam by empirically examining the ethnic wage gap in the Vietnamese labour market, using data from a large-scale household survey conducted in 2002. The paper uses the ‘index number’ decomposition method suggested by Oaxaca (1973) to decompose the ethnic wage gap into treatment and endowment effects at both the mean and at selected quantiles of the conditional wage distribution. The results confirm the existence of an ethnic wage gap in the labour market, through this gap is found to be substantially narrower than the ethnic gap observed using household living standard measures for Vietnam. Decomposition results reveal that the ethnic wage gap is largely attributable to differentials in the returns to endowments, a finding invariant to whether the mean or selected quantiles of the conditional wage distribution is examined.Wage inequality, ethnic minority, quantile regression, Vietnam

A theoretical model of the wave particle interaction of plasma in space

A theoretical model, based on the kinetic theory for the perturbation of plasma in the magnetosphere, is proposed to study the observed disturbances which are caused by both natural and artificial sources that generate wave-like perturbations propagating around the globe. The proposed model covers the wave propagation through a media of transitional (from collisional to collisionless) fully ionized magnetoactive plasma. A systematic formulation of the problem is presented and the method of solution for the transitional model of magnetosphere is discussed. The possible emission of hydromagnetic waves in the magnetosphere during the quiet and disturbed time are also discussed
