Rational Points on Weighted projective Spaces
In this paper,we count the rational points on the weighted projective spaces
defined over number fields w.r.t. ``size''. An asymptotic formula which
generalizes the result of Schanuel's ``Heights in number fields'' is obtained.
Furthermore, we count also the rational points on the product of weighted
projective spaces
A Smooth Coefficient Quantile Regression Approach to the Social Capital-Economic Growth Nexus
[[abstract]]This analysis assesses the role of social capital in generating heterogeneity in growth processes across U.S. counties by estimating growth regressions, using the novel semiparametric smooth coefficient quantile regression method in which parameters are unspecified functions of a measure of social capital. The results indicate substantial differences across the quantiles of economic growth in the profile shapes of the coefficient estimates over the level of social capital. Moreover, the coefficient function estimates are highly nonlinear over the level of social capital, providing evidence that the growth process that links initial income, education attainment, ethnic diversity, inequality, population density, and government activity to growth varies with social capital in a nonlinear way.[[notice]]補正完畢[[incitationindex]]SSCI[[booktype]]紙本[[booktype]]電子
