What constrains firms from divesting their legacy business?

This study focuses on a unique business phenomenon, legacy divestitures, which refers to the sale or spinoff of a firm's original business. I argue that firms may be prevented from engaging in legacy divestiture by organizational inertia, which become increasingly stronger as the legacy business gets older. I also examine factors that help firms overcome the constraints of inertial forces on firms' legacy divestitures. Hypotheses are tested using a sample of 108 diversified American companies, 27 of which divested legacy businesses between 1980 and 2017. Firms are less likely to divest their legacy businesses as the legacy units get older. The negative relationship is weakened by two factors, performance–aspiration gaps and R&D intensity.     

Sense of belonging,international migrants’ spending,and implications for their subjective well-being

A lack of a sense of belonging in the host country has become one of the most common challenges facing international migrants in today's sociopolitical environment. Our two online experiments with 881 international migrant workers in the United States jointly demonstrate that, to cope with their lack of a sense of belonging in the host country, international migrants may spend money suboptimally: more on material purchases but less on experiential and prosocial purchases. More importantly, our studies suggest that prosocial purchases are more effective than experiential purchases in increasing international migrants’ subjective well-being. This is because prosocial purchases can lead to both relatedness need satisfaction and beneficence, with each independently contributing to international migrants’ subjective well-being. Our research suggests that public policymakers should address the social exclusion international migrants experience when moving to a new country because it can have a negative impact on their subjective well-being. Our research further suggests that one way to mitigate social exclusion is to encourage international migrants to spend money on others rather than themselves.     

Does it matter where you invest? The impact of foreign direct investments on domestic job creation and destruction

This study examines how foreign direct investment (FDI) affects domestic employment by using unique division-level data of Japanese firms. Contrary to most previous studies focusing on the effect of FDI on net employment growth, we decompose it into job creation (JC) and job destruction (JD) for each individual firm. We find that FDI destination plays an important role: FDI to Asia increases JC, whereas FDI to Europe/North America decreases it; furthermore JD decreases, regardless of FDI destination. A frictional search-and-matching model with heterogeneous jobs can explain the differential effects. The model provides additional predictions on JC and JD by job type, which are also empirically confirmed.     

Asymptotic subadditivity/superadditivity of Value-at-Risk under tail dependence

This paper presents a new method for discussing the asymptotic subadditivity/superadditivity of Value-at-Risk (VaR) for multiple risks. We consider the asymptotic subadditivity and superadditivity properties of VaR for multiple risks whose copula admits a stable tail dependence function (STDF). For the purpose, a marginal region is defined by the marginal distributions of the multiple risks, and a stochastic order named tail concave order is presented for comparing individual tail risks. We prove that asymptotic subadditivity of VaR holds when individual risks are smaller than regularly varying (RV) random variables with index −1 under the tail concave order. We also provide sufficient conditions for VaR being asymptotically superadditive. For two multiple risks sharing the same copula function and satisfying the tail concave order, a comparison result on the asymptotic subadditivity/superadditivity of VaR is given. Asymptotic diversification ratios for RV and log regularly varying (LRV) margins with specific copula structures are obtained. Empirical analysis on financial data is provided for highlighting our results.     

不同生计模式下六盘山区易地扶贫搬迁移民生计资本耦合协调研究——以甘肃省古浪县为例

[目的]探究易地扶贫搬迁移民的生计耦合协调有助于全面了解移民的生计问题,对提高移民可持续生计能力及后续发展提供参考。[方法]文章以甘肃省古浪县易地扶贫搬迁家庭为研究对象,通过2019—2021年实地访谈和问卷调查等方法对移民家庭的生计状况进行调查,选取测度指标并计算各类移民的生计资本值,根据移民收入来源对生计模式进行分类,运用耦合协调度模型分析各生计模式下移民5项生计资本间的关系。[结果]（1）生计资本内部耦合水平总体较低,处于低度耦合和失调衰退等级;（2）非农型的生计资本耦合度和协调度最高,分别为0.299和0.230,是最为接近中度耦合和过渡协调阶段的生计模式;（3）两类兼业户的次之,处在（0.15,0.3）的区间内,属于低度耦合和衰退协调的中高级阶段;（4）纯农户的较低,为0.172和0.223,处于低度耦合和协调衰退的中阶段;（5）补贴户的最低,耦合度、协调度均在（0,1）的区间,处在低度弱耦合和恶性失调等级。[结论]古浪县不同生计模式下易地扶贫搬迁移民的生计资本存量和差距,导致其耦合协调性较差、差异较大。     

基于循环修正的城市房地产泡沫程度评价研究

房价高涨引发了学者们对我国城市房地产泡沫的争议。本文将理论研究与实证分析相结合,对我国房地产市场的泡沫程度进行研究,利用客观评价方法——主成分分析法,和主观评价方法——模糊层次分析法,针对我国房地产市场泡沫程度分别进行指标选择和评价,最后利用循环修正的思想对中国城市房地产泡沫评价体系进行修正、校对。通过对35个城市的房地产市场泡沫程度的评价,最后得出结论:35个城市房地产市场存在不同程度的泡沫,沿海城市的泡沫程度高于内陆城市。

风投是否有助于高科技企业联盟网络构建

以2009-2012年我国创业板的258家高科技上市公司为样本,实证检验风险投资对参股企业产生的信号传递效应。研究发现,风险投资参股对上市公司构建联盟网络具有正向影响。相对于声誉低的风险投资,声誉高的风险投资参股的上市公司具有较高网络中间中心度。进一步研究发现,从上市后的较长时期来看,声誉高的风险投资参股对提升公司网络中心度的影响具有持续性,与声誉低的风险投资差异明显。这两个检验都验证了声誉较高的风险投资机构具有经验和专业化上的优势,获得高声誉的风险投资机构参股可以向潜在合作者传递信号,从而促进联盟网络构建。
