Labor force participation and juvenile delinquency in Taiwan: a time series analysis 总被引:1,自引:1,他引:0
This study examines the null hypothesis of Granger no-causality between labor force participation (LFP) and juvenile delinquency
in Taiwan. In order to explore this issue more thoroughly, this study adopts the approach proposed by Toda and Yamamoto (1995,
Journal of Econometrics, 66(1–2), 225–250). It uses official time-series data provided by the Government of Taiwan. After estimating both a four- and
five-variable VAR system, one that substitutes both male and female LFP rates for the aggregate LFP rate, the primary findings
of this study reveal the following: The higher the past juvenile crime rate, the lower the future aggregate and female LFP
rate will be. In addition, the higher the past male LFP rate, the higher the future juvenile crime rate will be. These findings
are quite robust in terms of different lag-length structures.

基于奥地利学派的知识理论,企业演化的方法论应是个体与环境的互动主义。现代企业演化理论的核心概念是企业家精神、适应性学习和资本结构等,以此为基础建立的启发式的企业演化逻辑,可用于考察企业在不同的演化环境下所采取的不同内外部协调机制(紧密或松散)、学习模式以及知识类型(默会或编码)。此外,企业学习过程和选择过程是交互作用的,企业的创新活动必须考虑时间因素,这将使企业演化变得更加复杂。 相似文献

In recent decades, quantile regression has received much more attention from academics and practitioners. However, most of existing computational algorithms are only effective for small or moderate size problems. They cannot solve quantile regression with large-scale data reliably and efficiently. To this end, we propose a new algorithm to implement quantile regression on large-scale data using the sparse exponential transform (SET) method. This algorithm mainly constructs a well-conditioned basis and a sampling matrix to reduce the number of observations. It then solves a quantile regression problem on this reduced matrix and obtains an approximate solution. Through simulation studies and empirical analysis of a 5% sample of the US 2000 Census data, we demonstrate efficiency of the SET-based algorithm. Numerical results indicate that our new algorithm is effective in terms of computation time and performs well for large-scale quantile regression. 相似文献

We study the variable selection problem for a class of generalized linear models with endogenous covariates. Based on the instrumental variable adjustment technology and the smooth-threshold estimating equation (SEE) method, we propose an instrumental variable based variable selection procedure. The proposed variable selection method can attenuate the effect of endogeneity in covariates, and is easy for application in practice. Some theoretical results are also derived such as the consistency of the proposed variable selection procedure and the convergence rate of the resulting estimator. Further, some simulation studies and a real data analysis are conducted to evaluate the performance of the proposed method, and simulation results show that the proposed method is workable. 相似文献

Despite the continuous asymmetrical power relations between the Global North and South, the “global race for talent” is no longer a privilege enjoyed only by developed countries. Comparative analysis of policy content and effectiveness has attracted increasing interest. The examination of policy initiatives resulting in return migration of highly‐skilled migrants from the Global North to the Global South, however, remains inadequate. In this article, we provide a comparative analysis of policies targeting high‐level Chinese and Indian professionals including full‐time returnees. Two key differences in policy instruments and outcomes in the two countries are identified and they have implications for migration policies in other countries in the Global South and North. 相似文献
