高管持股与企业价值——基于利益趋同效应与壕沟防守效应的经验研究

本文以深交所78家民营上市公司为样本,从利益趋同效应和壕沟防守效应两方面研究了高管持股与企业价值的关系。与目前大多数相关研究不同,本文在计量高管持股比例时包括了高管人员通过间接方式持有的公司股权。本研究发现,高管持股比例不同引起的利益趋同效应和壕沟防守效应导致高管持股与企业价值之间呈显著的非线性关系。当高管持股比例在8%—25%之间,高管持股的壕沟防守效应占主导,而小于8%或大于25%时,高管持股的利益趋同效应占主导。研究结论对以激励为主要目的或以股权结构优化为主要目的的高管持股方案提供了经验证据。     

本子故事《羌胡传》对《蒙古秘史》情节的趋同性传承

文学的发展是一条历史长河,在它发展的下一阶层上,总是传承着上一阶层的源流,并且同时又接受着各种文学潮流的影响。本子故事《羌胡传》在故事的敘述中,与《蒙古秘史》的情节趋同,表现出蒙古族口头传统对书面文学的传承特色。     

农村产业融合发展对新型城镇化的影响--基于省际面板数据

本文厘清了农村产业融合发展影响新型城镇化的内在机制,并基于2007—2018年我国省际面板数据,运用空间计量模型进行实证检验。研究发现:(1)我国新型城镇化水平存在显著的正向空间相关性;(2)全国层面,农村产业融合发展对新型城镇化水平的提升产生显著的正向影响,且具有显著的正向空间溢出效应;(3)区域层面,东部、中部、西部农村产业融合发展对新型城镇化的直接和间接效应均显著为正,中部直接效应最大,东部间接效应最大。据此,本文提出健全金融支撑农村产业融合发展的体系、强化人才支撑农村产业融合发展的能力、推动农村产业融合多元化发展和加强区域间产业协调发展等建议。     

我国分季度GDP估算方法的研究

 近年来随着各国经济的不断融合和金融市场的日趋国际化,宏观经济的短期波动越来越受到各国的重视,季度GDP作为高质量的子年度统计数据可以说具有独特的研究价值,为此各国都在探讨季度GDP的核算方法,以获取更加及时、准确的统计数据。我国近两年经济波动较大,寻找及时、准确的高频数据进行短期经济分析具有重大意义。为此,本文借鉴国际上的Chou-Lin方法对我国季度GDP进行分产业的估算,并将估算结果与官方数据进行比较,发现估算结果与官方数据偏差极小,可以作为高频数据进行经济分析及预测。     

Assessing convergence diagnostic tests for Bayesian Cox regression

The Markov chain Monte Carlo (MCMC) method generates samples from the posterior distribution and uses these samples to approximate expectations of quantities of interest. For the process, researchers have to decide whether the Markov chain has reached the desired posterior distribution. Using convergence diagnostic tests are very important to decide whether the Markov chain has reached the target distribution. Our interest in this study was to compare the performances of convergence diagnostic tests for all parameters of Bayesian Cox regression model with different number of iterations by using a simulation and a real lung cancer dataset.     

M-estimation for functional linear regression

This paper studies M-estimation in functional linear regression in which the dependent variable is scalar while the covariate is a function. An estimator for the slope function is obtained based on the functional principal component basis. The global convergence rate of the M-estimator of unknown slope function is established. The convergence rate of the mean-squared prediction error for the proposed estimators is also established. Monte Carlo simulation studies are conducted to examine the finite-sample performance of the proposed procedure. Finally, the proposed method is applied to analyze the Berkeley growth data.     

Uniform Convergence of Compactly Supported Wavelet Expansions of Gaussian Random Processes

New results on uniform convergence in probability for expansions of Gaussian random processes using compactly supported wavelets are given. The main result is valid for general classes of non stationary processes. An application of the obtained results to stationary processes is also presented. It is shown that the convergence rate of the expansions is exponential.     

Convergence Rate of Wavelet Expansions of Gaussian Random Processes

This article characterizes uniform convergence rate for general classes of wavelet expansions of stationary Gaussian random processes. The convergence in probability is considered.     

Economic convergence and life satisfaction in the European Union

The issue of convergence or divergence in the European Union (EU) is usually viewed from a macroeconomic perspective, using indicators such as the income per head, the unemployment rate and the inflation rate. Little attention has been paid to the possibility of an associated convergence in ‘well-being’ across countries. Since recent literature has shown that subjective well-being (life satisfaction, ‘happiness’) is significantly affected by macroeconomic variables, it is natural to ask not only whether or not subjective well-being converges, but also, whether, how and to what extent this process is linked to macroeconomic convergence. In this paper we use self-rated life satisfaction elicited in large scale surveys to address these questions. We find evidence of convergence of life satisfaction across the member states of the EU, which can be attributed to a considerable extent to the convergence in macroeconomic conditions. Among the various macroeconomic indicators, the convergence in inflation rates has played a major role for the convergence in life satisfaction.
