孵化网络结构、风险传播对孵化网络最终健康水平的影响——结构可视化的调节作用

风险在孵化网络中的传播影响孵化网络健康水平,并会导致在孵企业高失败率与低成长率。为实现有效的网络治理,以两家国家级孵化器形成的实际网络为例,运用复杂网络理论中的SIR模型和仿真方法,模拟特定情境下风险在不同网络结构中的传播机理及其对孵化网络最终健康水平的影响。研究发现：孵化网络结构、风险传播与网络健康间具有显著相关性;在低初始健康分布情景下,无标度网络具有更快的恢复速度;在不同网络结构下,可视化水平均有助于提升孵化网络风险化解能力。     

外部掠夺下的国防开支与经济增长

本文建立了一个国际冲突环境中的一国经济长期增长模型。模型假定国际环境为霍布斯状态,一国不得不时刻面临外部掠夺,而阻止外部掠夺的唯一途径是投资国防。掠夺者、政府和家庭的动态博弈均衡决定了长期增长路径。分析表明,国际和国内因素两个层次的均衡决定了长期均衡增长路径;均衡增长路径可分为屈服均衡、容忍均衡和完全防卫均衡三个阶段;政府不同的国防战略会导致不同的增长图景,经济持续增长将导致国防战略的内生调整。     

Currency substitution and nonlinear error correction in Taiwan's demand for broad money

We modify the conventional money demand function by including a real exchange rate variable to reflect the effect of currency substitution. Empirical evidence indicates that the variable is crucial to the long-run stability of Taiwan's money demand. After finding the failure of a linear error-correction model (ECM) in describing the dynamics of Taiwan's money demand, we apply a nonlinear ECM to examine its dynamics and support the appropriateness of the nonlinear model empirically.     

The cyclicality of bank regulation in a general economic framework

This article utilizes a representative agent model to address how the regulation policies for banks should respond to the general economic condition. With the consideration of a self-fulfilling deposit insurance facility with sufficient bank reserve to meet the expected need of liquidity shock, our model suggests a counter-cyclical capital adequacy requirement in a competitive loan market. The exception might occur when the moral hazard problem becomes very unwieldy and the representative individual is rather risk averse. With regard to the closure policy, we find that it is closely related to the individual’s degree of risk aversion. A counter-cyclical closure policy is recommended when the individual is highly risk averse. Otherwise, a pro-cyclical closure policy is preferred.     

Religious pluralism and religious participation: a median-based approach to the non-substantive problem

Sociologists of religion have long been interested in the interaction between religious pluralism and religious vitality. Previous empirical studies approach this theme by drawing on data of denominational participation rates across geographical units, investigating the property of association between the quantity of one minus the Herfindahl–Hirschman Index (religious pluralism), and the total religious participation rate (religious vitality). However, this association could be theoretically spurious. Taking advantage of the median’s statistical property of being less sensitive to the variations of extreme values, this study proposes to apply the median instead of the arithmetic summation of religious participation rates to measure geographical-unit-level religious vitality. This method is illustrated by analyzing the New York State census of religion 1865 and the U.S. county survey 1990.     

How perceived empowerment HR practices influence work engagement in social enterprises – a moderated mediation model

Abstract

Drawing insights from the group engagement model and self-determination theory, our research explored the role of perceived empowerment human resource (HR) practices in the hybrid organizational form of social enterprise in China. Based on two studies, this paper developed and examined a moderated mediation model, linking perceived empowerment HR practices, identification motivation, work engagement, and authority work value. Specifically, in Study 1 we found perceived empowerment HR practices increased employees’ work engagement through enhancing employees’ identification motivation. In Study 2, we adopted a two-wave design to duplicate and extend this mediation model. A moderator, employees’ authority work value, was found to weaken both the mediation relationship, and the positive relationship between perceived empowerment HR practices and identification motivation. This study broadens the understanding of what social enterprises look like in alternative contexts, while providing an opportunity to explore how a HRM mechanism and its boundary condition function in large social enterprises in China.     

On the coexistence of money and higher-return assets and its social role

This paper adopts mechanism design to investigate the coexistence of fiat money and higher-return assets. We consider an economy with pairwise meetings where fiat money and risk-free capital compete as means of payment, as in [28]. The trading mechanism in pairwise meetings is chosen among all individually rational, renegotiation-proof mechanisms to maximize society?s welfare. We show that in any stationary monetary equilibrium capital commands a higher rate of return than fiat money.

Total‐Factor Energy and Emission Efficiencies of ASEAN and Other Asian Economies

This research uses the slack‐based measure data envelopment analysis to compute the energy and emission efficiencies of Association of Southeast Asian Nations (ASEAN) and other Asian economies during the 2001–2017 period, employs the Malmquist productivity index to check for the main source of efficiency score changes due to technical changes, and then applies panel Tobit regressions to determine the factors explaining the efficiencies. Our empirical results show that the energy efficiency scores of ASEAN economies had been catching up to other Asian economies after the Global Financial Crisis, whereas the emission efficiency scores of various ASEAN economies had been falling behind other Asian economies over the same period. The main source of efficiency score changes over time is efficiency changes and not technical changes. Decreases in the fossil fuel ratio of net electricity generation and the secondary industry ratio within total industry improve both lead to improvements in energy and emission efficiencies.
