沉淀成本效应的行为经济学分析

本文从行为经济学--心理理性角度阐述沉淀成本效应的理性逻辑,打破新古典经济学沉淀成本决策无关性命题,从而表明沉淀成本效应存在本身就是在心理成本约束条件下的一种理性行为.因此,一方面,需要承认和理解沉淀成本效应存在的普遍性;另一方面,需要采取恰当的正式和非正式制度安排克服沉淀成本效应,加强沉淀成本管理,从而创造出一个没有沉淀成本的市场经济体制.     

流转带来神奇——程小青《霍桑探案》、高罗佩《大唐狄公案》论

本文论述了三个相关层次的问题:程小青的<霍桑探案>和高罗佩的<大唐狄公案>是中国式的侦探小说和西方式的公案小说;他们这样创作是由于各自的文化、文学的"偏食"和"误读";"偏食"和"误读"是不同民族、国家文化、文学传播中的必然现象.     

投资率门限特征、消费促进与经济增长：1995-2007

 目前,国际经济形势欠佳,出口市场严峻,拉动内需成为我国经济工作重点,投资与消费的关系再次受到学界关注。本文阐述了投资率和消费率协调统一的关系,并运用1995-2007年中国省区面板数据,根据投资率的门限特征进行非线性回归。分析结果表明,投资率主要存在两个门限值,第一个门限值位于44%,在该值以下,消费率的提高显著促进了经济增长;第二个门限值为36%左右,在该值以下,消费率的提高进一步拉动经济增长速度。然而,单纯依靠消费需求拉动将导致投资不足的“陷阱”,为此,本文提出了两项政策建议：挖掘可极大拉动第二产业增长的新消费点;在东部和中西部之间实现有所差异的战略布局。     

公私合作制(PPP)可行性:以城市轨道交通为例的分析

公私合作制(Public-Private Partnership)的概念由英国最早提出,之后在全球范围内得到了推广和应用.然而公私合作制的概念并没有统一的认识.本文阐述了对公私合作制的理解,并从公共产品理论、政府管制理论以及项目区分理论分析了私人部门进入轨道交通行业的可能性,政府部门监管公私合作制的必要性.轨道交通公私合作制的可行性.     

倒"U"型轨迹与新生代农民工的社会流动——新生代农民工的流动史研究

本文基于2009年的调查数据,运用定量方法研究了新生代农民工的流动史.研究的基本发现是,频繁的流动和工作更换构成了新生代农民工重要的群体特征.虽然起初的流动更多地是因为有更好的工作机会,但并不是每次流动都是针对原有起点的一次提升.新生代农民工的社会流动总体上来说表现为一种倒"U"型的轨迹,即前几次流动是垂直的向上流动,但当流动次数达到某个特定的值以后,无论是流入地、职业类型、流动原因还是获得新工作的途径,都呈现出逆向选择或向下流动的特点.因而,流动虽是一个不断寻找更好发展机会的过程,也体现了新生代农民工的主体性和能动性,但过于频繁的流动反而不利于他们自身的发展.     

公共政策传递过程中科层损耗的博弈分析及启示

在公共政策传递过程中,公共政策制定者和地方执行者之间的互动构成了一种博弈关系.当公共政策制定者的效用函数与执行者的效用函数发生偏差时,个人价值最大化动机将导致执行者对公共政策作出符合其自身利益的理解并予以修正式执行,从而造成公共政策地方科层损耗,导致公共政策实际社会效益低于预期效益.本文在对地方科层损耗形成机制及其效应进行经济学分析的基础上,构建博弈模型深入阐释,并提出了相应的政策建议.该分析突出了对公共政策传递过程的研究,弥补了相关领域研究的不足,为提升公共政策执行效率、确保公共政策预期社会效益提供必要的理论支持.     

民族村寨旅游环境困境及路径选择

近些年来,我国少数民族地区村寨旅游业蓬勃发展,旅游经济活动日益频繁,但由于多种因素的影响,民族村寨旅游环境问题相继出现,造成旅游村寨自然生态环境的破坏和人文生态环境的失调,严重威胁了村寨居民的生产生活环境,影响了村寨旅游的可持续发展.因此,有必要从经济学的角度探讨村寨旅游环境问题,指出旅游经济活动所具有的外部不经济性、旅游环境的公产物品特性等因素是引起旅游环境问题的重要经济根源和根本原因,并就此提出解决旅游村寨环境问题的基本路径.     

Just Like in Their Home Country? A Multinational Perspective on Living Arrangements of Older Immigrants in the United States

Older immigrants are more likely to share residence with their adult children and other family members than are U.S.-born older adults. Because socioeconomic factors only partially explain these differences and direct measures of cultural preferences are seldom available, the persistently high rates of intergenerational coresidence among the older foreign-born are often interpreted as driven by cultural preferences and/or a lack of assimilation. To challenge this interpretation, this study investigates the extent to which older immigrants’ living arrangements deviate from those of older adults in their home countries. The analysis combines data on immigrants from the 2008–2012 American Community Survey (ACS) with census data from three major immigrant-sending countries: Mexico, the Dominican Republic, and Vietnam. Despite persistent differences from U.S.-born whites, coresidence in later life is significantly less common than in the sending countries among the older foreign-born who migrated as young adults, and especially among those who migrated as children. The older foreign-born who migrated after age 50, however, are more likely to coreside and less likely to live independently than the older adults in their home countries. The similarity of these patterns across the three immigrant subgroups suggests that the unusually high coresidence among late-life immigrants is driven by U.S. family reunification policy and not simply by cultural influences.     

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.     

An exploratory study of early professional experiences and job burnout among BSW graduates in China

Although previous studies have addressed turnover issues among social workers in Western countries, this study explores the early professional experiences (during the first 3 working years) and job burnout among BSW graduates in China and identifies factors influencing their decisions to leave social work jobs. Using semi-structured interviews with 15 BSW graduates in the Shenzhen metropolitan area, this research identifies the primary reasons new social workers leave the profession. Data analysis revealed three themes: personal struggles, work environment issues, and social support factors. This exploratory study highlights the professional experiences and burnout among BSW graduates in China and has implications for social work education and professional practices.
