Productivity dynamics and the cleansing effect of two recessions: Evidence from the manufacturing sector in Korea

In general, recessions provoke the exit of a greater number of firms from the market. Less productive firms are more likely to exit and release their former resources to the remaining, more productive firms. The present study investigates two recessions in Korea: the Asian financial crisis and the global financial crisis. The main objective of the present study is to analyse the process of creative destruction in a recession, specifically the cleansing effect. We measured total factor productivity using micro‐level manufacturing plant data from 1993 to 2013. We decomposed the source of the changes in total factor productivity to measure the cleansing effect in two large recessions. During the first recession in the 1990s, there was no evidence to support a cleansing effect hypothesis. In contrast, during the second recession in the 2000s, there was evidence of a cleansing effect. In addition, we found differences in market selection criteria in the two recessions; by the second crisis, the market selection criteria had changed to enable a more conducive environment for the creative destruction process.     

A bootstrap test for jumps in financial economics

An i.i.d. bootstrap is applied for the ratio test of Barndorff-Nielsen and Shephard (2006) for jumps in jump diffusion processes. Asymptotic validity is established for the bootstrap test both under the null of no jump and under the alternative of jumps. Finite sample simulation shows that the bootstrap test has more stable size than the ratio test of Barndorff-Nielsen and Shephard (2006).     

对驰名商标“异化”的另一种认识

驰名商标的异化不仅指认定过程中的反常现象,还包括使用过程中的反常现象。用另一种眼光看,驰名商标的异化并非总是有害的,它还有促进商标法制建设、推动品牌的创造及其价值的发挥、营造良好的品牌文化等积极功能。因此,对驰名商标的异化现象应当区别对待,容忍具有较强正当性的异化现象,对于危害较大的异化现象则应采取多种措施予以消除。

人口理论视野下的老龄化问题分析

在以生育率降低为核心的人口转变过程中，不可避免地出现了一系列的老龄化问题。传统的计划生育政策直接加剧了我国老龄化的进程，对于现行的计划生育政策的调整势在必行；同时，在退休体制上，弹性退休制的提出将从另一个侧面缓解严峻的老龄化问题。     

税务专业硕士(MT)培养模式创新研究

税务专业硕士(MT)培养尚处于摸索和起步阶段。文章从MT教育的逻辑起点即环境分析入手,以国内35家MT培养单位为研究对象,认为受传统学术型研究生"重科研轻实践"培养观念的影响,MT教育的发展遇到了很多困难,培养效果与预期目标之间存在较大差距。Boyer理论从拓宽的学术内涵看待专业硕士的培养,有助于正确推动MT教育的发展,满足我国经济社会发展对高级涉税人才的需求。     

浅析互动式教学法在《食品安全性》教学中的应用

相对于传统的单向式教学法而言,互动式教学法不失为一种很好的教学方法,它能在教学过程中充分发挥教师和学生双方的主观能动性,通过师生之间、学生与学生之间、学生与消费群体之间的对话、讨论等多种方式,以达到思想、理论和信息的交流与启发,提高学生的学习热情,注重个性发展,培养学生的综合素质。本文详细论述了互动式教学法在《食品安全性》课程教学中的应用。     

Dynamic network design for reverse logistics operations under uncertainty

The design of reverse logistics network has attracted growing attention with the stringent pressures from environmental and social requirements. In general, decisions about reverse logistics network configurations are made on a long-term basis and factors influencing such reverse logistics network design may also vary over time. This paper proposes dynamic location and allocation models to cope with such issues. A two-stage stochastic programming model is further developed by which a deterministic model for multiperiod reverse logistics network design can be extended to account for the uncertainties. A solution approach integrating a recently proposed sampling method with a heuristic algorithm is also proposed in this research. A numerical experiment is presented to demonstrate the significance of the developed stochastic model as well as the efficiency of the proposed solution method.
