我国经济结构动态变动后的下一步

经济的非平衡增长近年来在宏观经济的研究中广受关注。利用1952～2009年的样本数据,分析检验发现,我国经济具有非平衡增长的基本特征,这导致了我国经济结构的升级演进路径呈现出结构转变性质;在所选择的样本期内,农业对经济增长的拉动作用呈现出倒U型曲线的特征,而服务业对经济的贡献则表现出逐步增加的势头。另外,经验分析的结果表明,我国经济可能正经历长期的结构调整。因此,采取合适的措施使我国经济持续长久增长至关重要。     

20世纪前期买办职业收入分析

20世纪前期,买办的职业报酬制度达到成熟和完善。买办的职业收入主要由薪金和佣金构成,还有一部分被外商默许的暗中收入。佣金是多数买办的主要收入,是买办经纪人身份的体现;薪金是买办与外商雇佣关系的一种象征。买办收入的复杂挂还在于不同行业的买办收入来源不一,且差距较大。     

Pay as incentive or pay as reward? The case of Taiwan

By the 1980s, Taiwan had gradually transformed itself from an economy in which labor was plentiful, while capital was in short supply, into an economy in which a surplus of capital was accompanied by a shortage of labor. For labor economists interested in rapidly evolving labor markets, there are many intriguing questions arising out of this transition. This study explores how conventional labor market and efficiency wage theories apply during this transformation. Based on monthly data over the period 1982–2007, we examine the linear causality between pay and productivity using Geweke's [Geweke, J. (1982). Measurement of linear dependence and feedback between multiple time series. Journal of the American Statistical Association, 77, 304–313] linear feedback technique. The results indicate that both pay as reward and pay as incentive behaviors are significant in the Taiwanese economy, with pay as incentive especially strong in the manufacturing sector.     

Financial Development,Interest Rate Liberalization,and Macroeconomic Volatility

This article examines the relationship between financial development, interest rate liberalization, and macroeconomic volatility in fifty-six emerging and developed economies over the period 1980–2009. We find that financial development plays a significant role in dampening the volatility of macroeconomic growth rate, but up to a limit. The more the interest rate is liberalized, the more likely that financial development can stabilize the economy. Particularly, interest rate liberalization has a more positive influence on emerging and developing countries. Financial development and interest rate liberalization can also alleviate the influence of external shocks. They mutually enhance their functions as economic stabilizers.     

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。     

国家高新区能否提升城市创新水平?

文章基于2003年至2016年我国215个城市面板数据，运用双重差分模型、空间双重差分模型和分位数回归模型等方法，实证检验了国家高新区对城市创新水平的影响及其空间异质性特征。研究结果表明，国家高新区建设显著提升了城市创新水平，并且高新区设立带动的城市投资集聚是推动城市创新水平提升的重要原因。空间双重差分结果表明，国家高新区对城市创新水平的提升作用并非源于其对周边城市创新资源的掠夺，相反高新区设立对周边城市和省内城市均产生了显著的溢出效应，提升了本省城市和周边外省城市创新水平。此外，国家高新区对城市创新水平的影响具有空间异质性特征，在省会城市、直辖市和副省级城市，高新区对城市创新水平的影响并不显著，而能够显著提升一般地级市创新水平；随着城市创新水平的提升，高新区建设对城市创新水平的促进作用呈现出先增强、后减弱直至不再显著的非对称"倒V型"变化特征。但是研究也发现，国家高新区对城市创新水平影响的区位异质性并不显著，高新区对东部地区和中西部地区城市创新水平提升均具有显著的促进作用。
