We develop a quantitative theory of human capital investment in order to evaluate the magnitude of cross-country differences in total factor productivity (TFP) that explains the variation in per-capita incomes across countries. We build a heterogeneousagent economy with cross-sectional variation in ability, schooling, and expenditures on schooling quality. In our theory, the parameters governin...

Recall that E denotes the number of red edges, and F denotes the total number of edges. Then E = ξF = ξNΛ′(1) with ξ defined appropriately. In this lecture we use the saddle point method to derive an approximation to coeff [∏kmax k=2 qk(z) MPk , zE ] , where qk(z) = 12 ((1 + z) n + (1− z)n) = ∑ r even ( k r ) zr. This coefficient counts the number of ways to choose which edges incident to the c...

In this paper, we investigate numerical approximations of the scalar conservation law with the Caputo derivative, which introduces the memory effect. We construct the first order and the second order explicit upwind schemes for such equations, which are shown to be conditionally 1 contracting and TVD. However, the Caputo derivative leads to the modified CFL-type stability condition, ( t) = O( x...

This paper presents the results of three psychophysical experiments designed to investigate the effects of spatial correlations and the disruption of global precedence on the visual fidelity of natural images. The first two experiments used a psychophysical scaling paradigm in which subjects placed distorted images along a linear, one-dimensional “distortion axis” where physical distance corres...

China's rapid and uneven growth since 1978 has not eliminated but even reinforced the persistent income inequality across provinces. While existing literature focuses mainly on the provincial variation in growth performance using cross-province growth regressions or growth accounting, few efforts has been made to directly study the differences in income levels across provinces. This paper explo...
