Detecting parameter shift in garch models

This paper applies recent theories of testing for parameter constancy to the conditional variance in a GARCH model. The supremum Lagrange multiplier test for conditional Gaussian GARCH models and its robustified variants are discussed. The asymptotic null distribution of the test statistics are derived from the weak convergence of the scores, and the critical values from the hitting probability of squared Bessel process.

Monte Carlo studies on the finite sample size and power performance of the supremum LM tests are conducted. Applications of these tests to S&P 500 indicate that the hypothesis of stable conditional variance parameters can be rejected.     

Institutional Voids,Economic Adversity and Inter‐firm Cooperation in an Emerging Market: The Mediating Role of Government R&D Support

This paper examines the mediating mechanism of the relationship between institutional voids (IVs) and inter‐firm cooperation and the moderating role of economic adversity in the context of small and medium‐sized enterprises (SMEs) based in emerging markets. The hypotheses are tested using time‐lagged survey data from 214 SMEs in Ghana. The findings provide support for the hypotheses by showing that: (1) IVs positively influence the use of government research and development (R&D) support; (2) the use of government R&D support mediates the relationship between IVs and inter‐firm cooperation; and (3) economic adversity positively moderates the relationship between IVs and the use of government R&D support. The findings contribute to understanding the role of IVs in inter‐firm cooperation. The wider implications for theory and practice are examined.     

教育政策的利益分析——以择校问题为例

利益是公共政策分析的基本范畴,实现公共利益是教育政策制定最重要的目标。教育政策的利益分析包括利益主体分析、利益需求分析、利益实现方式分析以及利益结果分析四个方面。从利益分析的角度来看,择校问题实际上是由于优质教育资源供需矛盾而导致的,其中教育资源分配不均衡是根本原因。择校代表了一种个人的基本权利,体现的是个人利益。通过改革不合理的教育供给方式、增加教育服务供给,是治理择校问题、平衡公共利益和私人利益的有效途径。     

论领导权结构、企业避税与会计信息可靠性的关系

以我国2013—2015年沪深两市A股类上市公司为样本,运用相关性分析和回归分析,以消除应计利润影响后的会计—税收差异作为衡量企业避税指标,用盈余激进度衡量会计信息可靠性,分析企业避税程度与会计信息可靠性的关系,并进行了稳健性检验。结果表明,企业避税程度对会计信息可靠性起负面作用。在此基础上,进一步梳理了领导权结构、企业避税与会计信息可靠性的关系,研究发现,相比两职合一的公司,企业避税程度对会计信息可靠性的负面作用主要体现在两职分离的公司。这对于深入研究企业避税与会计信息可靠性的关系具有一定的借鉴意义,可为完善公司治理机制、提高会计信息可靠性提供一定的思路借鉴和决策参考。

Financial journeys of Australian parents after separation – transitions into and out of poverty

It is well established that relationship separation has greater negative economic consequences for mothers than for fathers in Australia and other developed countries. While research has shown that, at an aggregate level, such negative impacts tend to diminish with time, the rate of change is generally slower for mothers than fathers, and a higher proportion of mothers than fathers continue to experience entrenched financial difficulties. Less is known about the variability of economic journeys experienced by women and men, taken separately, and factors influencing diverse economic trajectories. Drawing on data from the Longitudinal Study of Separated Families (LSSF), which followed up a large sample parents at three post‐separation points, this article examines poverty rates across a 4‐year period, transitions into and out of poverty and factors affecting these pathways.
