Knowledge capital,CEO power,and firm value: Evidence from the IT industry

Disruptive innovation dramatically changes the demand of a product market in the information technology (IT) industry. In response to the impact of disruptive innovation, IT firms that may be eliminated from the competitive race actively develop innovative products and adjust their operating strategies to strengthen their survivability in the fiercely competitive market. Thus, this study explores the factors that affect firm value in the IT industry under the impact of disruptive innovation. The empirical results reveal that knowledge capital and CEO power play crucial roles in explaining firm value. IT firms with powerful CEOs and increased knowledge capital have high firm values. The effects of knowledge capital and CEO power on firm value are especially significant for founder and duality CEO firms. Furthermore, the influence of CEO power is more prominent in periods of financial crisis.     

Effects of financial constraints on export performance of firms during the global financial crisis: microeconomic evidence from Korea

This study uses a manufacturing firm-level panel data set of South Korea for 2006–2013 to investigate the effect of financial constraints on the export performance of firms, with particular emphasis on the corporate ownership structure. The empirical results show that foreign multinational corporation (MNC) subsidiaries are not affected by financial constraint during both crisis and noncrisis periods, implying advantages of foreign ownership. However, domestic firms suffer more from financial constraints on exports during crisis years. In particular, domestic firms without parent firms are financially constrained during both crisis and noncrisis periods. However, those with parent firms do not experience financial constraints during noncrisis periods, although they too suffer from them during crisis periods. Thus, parent–subsidiary linkage among domestic firms plays an important role in alleviating financial constraints on export activity in noncrisis years but not as much during crisis years. Therefore, domestic parent firms exhibit less resilience to the global financial crisis, in comparison to foreign MNC parent firms.     

人民币跨境流动自由度的测算——基于资本项目名义开放指数的借鉴

长期以来,人们只看重货币国际化结果,以占全球贸易计价结算比重、外汇交易比重、国际债券比重、外汇储备比重等相关指标衡量一国货币的国际化程度,而忽视货币跨境流动放松过程,即一国货币的跨境流动自由化程度。货币国际化是一个过程又是一种结果,包含进程和结果两个层面,在货币国际化进程中,过早过快放松本币流出入会引发经济金融风险,某些情形下进程比结果更值得关注。构建人民币跨境自由度指数涉及强度赋值、项目设置和权重确定三方面内容。在梳理2019年第2季度前我国货币政策基础上,对2008年至2019年经常项目下的人民币跨境流动自由度、证券投资项目下的人民币跨境流动自由度以及资本项目下的人民币跨境流动自由度进行评估,并以美国近5年各项目下的资金流动平均占比为权重,构建了人民币跨境流动自由化指数,考察2008—2019年人民币跨境流动自由化程度,结果显示人民币国际化进展较快,跨境流动已得到很大程度放松,而且人民币流入自由程度显著高于流出自由度。我国人民币国际化进程应持续遵循先经常项目后资本项目、先流入后流出、先机构后个人、先大额后小额、先风险小项目后风险大项目的次序,提高人民币跨境流动的稳定性,降低无序流动的投机风险;严格管控证券投资、其他投资、衍生品项目下人民币跨境流动,并依据我国利率市场化程度、金融市场发达程度及审慎监管能力进行调整;大力提升经常项目的人民币结算比重,发展人民币离岸市场,提高非居民间的人民币使用频率和使用规模;充分评估各项目下人民币跨境流动和本外币兑换自由度,提高两者的协同匹配程度,降低因两者不匹配而产生的负面影响。     

生计资本对黄土丘陵区贫困人口生计活动的影响及评价*——以甘肃省榆中县为例

［目的］通过深入研究黄土丘陵区贫困人口生计资本对生计活动的影响，为解决农村贫困问题，提升农户生计资本存量、实现区域可持续生计发展提供科学依据。［方法］文章以甘肃省榆中县为例，基于对榆中县农户的调查数据，采用熵值法分析了东北部山区、中部川区和西南部山区贫困人口的生计资本状况和生计活动方式，并对其生计活动进行评价。［结果］从农户的生计资本组合来看，榆中县整体自然资本和人力资本相对物质资本、金融资本、社会资本3类资本较为富裕，尤其在西南部山区和东北部山区3类资本缺乏型农户比例较高。中部川区各乡镇人口的总体生计资本状况较好，总指数最高，而西南部山区次之、东北部山区最低，两者生计资本状况总体匮乏。农户的生计活动主要以种植、养殖和外出打工为主，生计活动多样性程度偏低； 中部川区人口的生计活动多样性指数最高，西南部山区次之、东北部山区最低，且整体受教育程度偏低，加之物质资本、金融资本、社会资本缺乏进一步限制了当地农户的生计多样性。［结论］（1）针对不同生计资本水平和生计活动多样性程度偏低的贫困地区，需要进一步发挥民族文化产业扶贫优势，开启地域产业扶贫新模式，打造地域无公害特色农业产业品牌，提高农户物质资本边际贡献； （2）发展小额信贷金融服务，改善农户金融资本存量，预防村际农户金融资本二元极化； （3）实施免费教育培训技能学习，打造教育培训脱贫示范村，提高人力资本存量，缓解贫困人口生计压力等提高经济发展水平的扶贫政策措施。     

社会资本视角下农村基础设施管护效果影响因素分析——基于甘肃省9个市县的实证研究

以甘肃省9个县市的调查数据为基础,将社会资本划分为社会参与、社会规范、互惠网络三个维度,运用结构方程模型,来探讨三个维度对农村基础设施管护效果的影响。结果表明:(1)社会规范对农村基础设施管护效果显正向影响。(2)互惠网络对农村基础设施管护效果显负向影响。(3)社会参与对农村基础设施管护效果的直接影响不显著,但通过社会规范及互惠网络间接产生影响。(4)就总效应而言,社会规范对农村基础设施管护效果的影响要大于社会参与及互惠网络产生的影响。     

The impact of COVID-19 on the G7 stock markets: A time-frequency analysis

We examine the co-movement of the G7 stock returns with the numbers of confirmed COVID-19 cases and causalities based on daily data from December 31, 2019 to November 13, 2020. We employ the wavelet coherence approach to measure the impact of the numbers of confirmed cases and deaths on the G7 stock markets. Our findings reveal that both the number of confirmed COVID-19 cases and the number of deaths exhibit strong coherence with the G7 equity markets, although we find heterogeneous results for the Canadian and Japanese equity markets, in which the numbers of COVID-19 cases and the deaths exhibit only a weak relationship. This evidence is more pronounced in the long-term horizon rather than the short-term horizon. Moreover, the lead-lag relationship entails a mix of lead-lag relations across different countries. We present the implications of these findings for both policymakers and the international investment community.     

The effects of credit default swaps on corporate investment

ABSTRACT

This paper examines how credit default swaps (CDS) affect the corporate investment of the referenced entities. We document a significant reduction in corporate investment after CDS trading, a result that is robust to alternative model specifications and a set of endogeneity tests. Our findings of the increased firm risk and cost of capital support the costly external capital channel. The cross-sectional variations in CDS effects demonstrate that both reduced monitoring and the empty creditor problem might be the underlying forces driving the costly external capital channel. Our additional analysis implies that CDS trading is associated with an enhancement in investment efficiency for firms that are prone to overinvestment.     

Microfinance and social capital formation- a social network analysis approach

The microcredit program has emerged as an important poverty alleviation strategy over the last three decades, and several studies have examined its economic impacts on the community well-being. However, far too little attention has been paid to the effects of micro credits on community social connection and solidarity. This paper aims to examine the application of Social Network Analysis (SNA) to explore the impact of the rural microcredit fund on community social capitals. In doing so, the data on interactions of four rural development groups' members before and after the microcredit project implementation were collected using participatory workshops in Neyzar village of Qom province in Iran. The data were analyzed by Ucinet software, and the socio-graphs were produced by the NetDraw application. The results show that, more people have been involved in the social interactions after the project implementation and there was statistically significant increase in density and decrease in centralization of cooperation network. Furthermore, there were no important distinctions in centrality of people with various educational levels before and after the project implementation. Overall, it can be concluded that, the microfinance initiative considerably promotes the community social capital and participation in the rural development activities. Moreover, the SNA techniques are applicable as an impact assessment tool to investigate changes in community social capital.     

Foreign investment regulation and firm productivity: Granular evidence from Indonesia

When regulating foreign direct investment (FDI), countries often face a trade-off between pursuing national policy interests and suffering efficiency losses due to FDI restrictions. We demonstrate the presence of this trade-off in the case of a protectionist FDI policy in Indonesia. Using a yearly census of Indonesian manufacturing firms from 2000 to 2015, we link product-level changes in binding FDI regulation due to major regulatory tightening to changes in firm-level productivity. Controlling for an extensive set of fixed effects as well as potential political economy drivers of regulation, we show that a tightening of the regulatory environment was successful in reducing foreign capital reliance among regulated firms, and led to increases in FDI among non-regulated firms producing the same product. Despite compensating increases in domestic capital, regulated firms experienced relative productivity losses. This points towards either a less efficient allocation of domestic capital or a general inferiority of domestic capital as compared to foreign investments.
