Access to Higher Education and Inequality: The Chinese Experiment

We apply a semi-parametric latent variable model to estimate selection and sorting effects on the evolution of private returns to schooling for college graduates during China’s reform between 1988 and 2002. We find that there were substantial sorting gains under the traditional system, but they have decreased drastically and are negligible in the most recent data. We take this as evidence of growing influence of private financial constraints on decisions to attend college as tuition costs have risen and the relative importance of government subsidies has declined. The main policy implication of our results is that labor and education reform without concomitant capital market reform and government support for the financially disadvantaged exacerbates increases in inequality inherent in elimination of the traditional "wage-grid."Return to schooling, selection bias, sorting gains, heterogeneity, financial constraints, comparative advantage, China

Sorting, Selection, and Transformation of the Return to College Education In China

We estimate selection and sorting effects on the evolution of the private return to schooling for college graduates during China’s reform between 1988 and 2002. We pay special attention to the changing role of sorting by ability versus budget-constraint effects as China’s education policy has changed from one in which the bulk of direct costs are paid by government for students who pass a rigid set of test to one in which freedom of choice is increasingly the rule for those who can afford to pay for tuition and living expenses while acquiring higher education. We find evidence of substantial sorting gains under the traditional system but that gains have diminished and even become negative as schooling choices widened and participation has become subject to increasing direct private costs. We take this as evidence consistent with the influence of financial constraints on decisions to attend college.http://deepblue.lib.umich.edu/bitstream/2027.42/40142/3/wp756.pd

Human Capital, Economic Growth, and Regional Inequality in China

We show how regional growth patterns in China depend on physical,, human, and infrastructure capital; foreign direct investment (FDI); and market reforms, especially the reforms that followed Deng Xiaoping’s South Trip in 1992 those that resulted from serious hardening of budget constraints of state enterprises around 1997. We find that FDI had a much larger effect on TFP growth before 1994 than after, and we attribute this to the encouragement of and increasing success of private and quasi-private enterprises. We find that human capital positively affects output per worker and productivity growth in our cross-provincial study. Moreover, we find both direct and indirect effects of human capital on TFP growth. The direct effect is hypothesized to come from domestic innovation activities, while the indirect impact is a spillover effect of human capital on TFP growth. We conduct cost-benefit analysis of hypothetical investments in human capital and infrastructure. We find that, while investment in infrastructure generates higher returns in the developed, eastern regions than in the interior, investing in human capital generates slightly higher or comparable returns in the interior regions. We conclude that human capital investment in less-developed areas can improve economic efficiency, neither investment strategy is a magic bullet for reducing China’s regional income disparities.

A Spatially Coupled LDPC Coding Scheme with Scalable Decoders for Space Division Multiplexing

In this paper, we study the application of spatially coupled LDPC codes with sub-block locality for space division multiplexing. We focus on the information exchange between the sub-blocks and compare decoding strategies with respect to the complexity, performance and the information flow.Comment: 3 pages plus comments, 3 figures, European Conference on Optical Communication (ECOC) 202

Human Capital, Economic Growth, and Regional Inequality in China

We study the dispersion in rates of provincial economic- and TFP growth in China. Our results show that regional growth patterns can be understood as a function of several interrelated factors, which include investment in physical capital, human capital, and infrastructure capital; the infusion of new technology and its regional spread; and market reforms, with a major step forward occurring following Deng Xiaoping’s “South Trip” in 1992. We find that FDI had much larger effect on TFP growth before 1994 than after, and we attribute this to emergence of other channels of technology transfer when marketization accelerated. We find that human capital positively affects output per worker and productivity growth. In particular, in terms of its direct contribution to production, educated labor has a much higher marginal product. Moreover, we estimate a positive, direct effect of human capital on TFP growth. This direct effect is hypothesized to come from domestic innovation activities. The estimated spillover effect of human capital on TFP growth is positive and statistically significant, which is very robust to model specifications and estimation methods. The spillover effect appears to be much stronger before 1994. We conduct cost-benefit analysis and a policy “experiment,” in which we project the impact increases in human capital and infrastructure capital on regional inequality. We conclude that investing in human capital will be an effective policy to reduce regional gaps in China as well as an efficient means to promote economic growth.http://deepblue.lib.umich.edu/bitstream/2027.42/57237/1/wp857 .pd

Quaternary Neural Belief Propagation Decoding of Quantum LDPC Codes with Overcomplete Check Matrices

Quantum low-density parity-check (QLDPC) codes are promising candidates for error correction in quantum computers. One of the major challenges in implementing QLDPC codes in quantum computers is the lack of a universal decoder. In this work, we first propose to decode QLDPC codes with a belief propagation (BP) decoder operating on overcomplete check matrices. Then, we extend the neural BP (NBP) decoder, which was originally studied for suboptimal binary BP decoding of QLPDC codes, to quaternary BP decoders. Numerical simulation results demonstrate that both approaches as well as their combination yield a low-latency, high-performance decoder for several short to moderate length QLDPC codes.Comment: arXiv admin note: text overlap with arXiv:2212.1024

Human Capital In China

In this paper we estimate China’s human capital stock from 1985 to 2007 based on the Jorgenson-Fraumeni lifetime income approach. An individual’s human capital stock is equal to the discounted present value of all future incomes he or she can generate. In our model, human capital accumulates through formal education as well as on-the-job training. The value of human capital is assumed to be zero upon reaching the mandatory retirement ages. China’s total real human capital increased from 26.98 billion yuan in 1985 (i.e., the base year) to 118.75 billion yuan in 2007, implying an average annual growth rate of 6.78%. The annual growth rate increased from 5.11% during 1985-1994 to 7.86% during 1995-2007. Per capita real human capital increased from 28,044 yuan in 1985 to 106,462 yuan in 2007, implying an average annual growth rate of 6.25%. The annual growth rate also increased from 3.9% during 1985-1994 to 7.5% during 1995-2007. Therefore, although population growth contributed significantly to the total human capital accumulation before 1994, per capita human capital growth was primary driving force after 1995. The substantial increase in educational attainment during 1985-2007 contributed significantly to the growth in total and per capita real human capital.
