Analysis of Gender Wage Differential in China's Urban Labor Market

This paper estimates the gender wage gap and its composition in China's urban labor market using the 2009 survey data from the Chinese Family Panel Studies. Several estimation and decomposition methods have been used and compared. First, we examine the gender wage gap using ordinary least square regression method with a gender dummy variable. Then, we apply Oaxaca (1973) decomposition method with different weighting systems to analyze the logarithmic wage differential. To be more specific, we prove the existence of sample selection bias caused by the female's labor force participation. We eliminate it by using the Heckman's two-step procedure. Empirical results reveal that male workers generally receive a higher wage than female workers, and a great deal of this difference is unexplained. Meanwhile, this unexplained part, which is usually referred to as discrimination turns out to be higher when the adjustment is made for the selection bias. A further breakdown of the wage gap shows that among all the individual characteristics, occupations explain the largest share of the wage gap, followed by their working experience. On the other hand, education acts as a contributor for discrimination in the labor market.discrimination, wage gap, decomposition, gender, Chinese labor market

Development and Sources of Labor Productivity in Chinese Provinces

As China exhibited unprecedented rapid economic growth ever since its reform and openness, the development and sources of labor productivity has gradually come to the forefront. This paper studies the development and the source of labor productivity in 31 Chinese provinces during the period of 2000-2009. The labor productivity is investigated through an examination at both the levels and the growth rate. Particularly, we first look at the production function relationship, to see the contribution of labor and other production factors to the gross domestic product. Then, a number of possible determinants are defined. They are regressed on the level and the growth rate of labor productivity to shed light on their relationships. Controlled for unobserved time-specific and province-specific effects, the fixed effects model with heteroskedasticity robust adjustments have been used for the estimation of three functions. Regional breakdown shows severe disparity in the economy where three municipal cities have the highest labor productivity among other regions. Subsequently, we summarize the different sources and their contributions to labor productivity and provide several policy suggestions.development, labor productivity, labor productivity growth, provinces, China

The Optical -- Mid-infrared Extinction Law of the l=165 Sightline in the Galactic Plane: Diversity of Extinction Law in the Diffuse Interstellar Medium

Understanding the effects of dust extinction is important to properly interpret observations. The optical total-to-selective extinction ratio, Rv = Av/E(B-V), is widely used to describe extinction variations in ultraviolet and optical bands. Since the Rv=3.1 extinction curve adequately represents the average extinction law of diffuse regions in the Milky Way, it is commonly used to correct observational measurements along sightlines toward diffuse regions in the interstellar medium. However, the Rv value may vary even along different diffuse interstellar medium sightlines. In this paper, we investigate the optical--mid-infrared (mid-IR) extinction law toward a very diffuse region at l = 165 in the Galactic plane, which was selected based on a CO emission map. Adopting red clump stars as extinction tracers, we determine the optical-to-mid-IR extinction law for our diffuse region in the two APASS bands (B, V), the three XSTPS-GAC bands (g, r, i), the three 2MASS bands (J, H, Ks, and the two WISE bands (W1, W2). Specifically, 18 red clump stars were selected from the APOGEE--RC catalog based on spectroscopic data in order to explore the diversity of the extinction law. We find that the optical extinction curves exhibit appreciable diversity. The corresponding Rv ranges from 1.7 to 3.8, while the mean Rv value of 2.8 is consistent with the widely adopted average value of 3.1 for Galactic diffuse clouds. There is no apparent correlation between Rv value and color excess E(B-V) in the range of interest, from 0.2 to 0.6 mag, or with specific visual extinction per kiloparsec, AV/d.Comment: 28 pages, 7 figures, accepted for publication in The Astrophysical Journa
