Top management team social capital,exploration-based innovation,and exploitation-based innovation in SMEs

Despite increasing interest in ambidextrous innovations, mainstream literature has excluded discussions on developing and combining exploratory innovation (ERI) and exploitative innovation (EII) in the small- and medium-sized enterprise (SME) sector. This issue from the SME perspective is worth addressing. Recent studies have conceptually argued the importance of the top management team (TMT) in managing ambidextrous innovations. Building on this argument, we explore how the top manager external social relationships foster ambidextrous innovations and whether internal social relationships among senior executives can be used to integrate such innovations. The results show that (a) distinct external managerial relationships cause differential innovations for SMEs, and (b) internal social capital among top managers could be used effectively to manage ambidextrous innovations. This research indicates that SMEs engaging in both high ERI and EII perform better when they focus on the balancing benefits of TMT internal social capital and the bridging benefits of TMT external social capital.     

Latin America after the global crisis: the role of export-led and tradable-led growth regimes

Is the ongoing economic slowdown in industrialized countries likely to impact Latin American growth negatively in the medium- to long-run? This paper considers various transmission channels that work through trade in goods and services, and finds econometric evidence suggesting that shrinking global imbalances may create problems for Latin America. Specifically, using panel data analysis, we find that the trade balance as a proportion of GDP is positively associated with Latin American economic growth over the period 1953–2009. We then develop a simple dynamic model to help explain our main finding through investment and saving behaviour.     

Cash holdings and business group membership

This study examines the cash policies of business group members (i.e., affiliates). Using a panel dataset of private Belgian affiliates and comparable non-affiliated firms, the empirical results show that business group affiliates hold significantly smaller amounts of cash as compared to non-affiliated firms. This finding is consistent with the notion that affiliates can afford to keep lower cash reserves because these firms can access the internal capital market of the group. The analysis also combines affiliate level and group level data to evaluate cash drivers and shows that groups in financial distress reduce cash holdings in affiliates. However, affiliates that are more important for the group's reputation and operations maintain cash levels comparable to affiliates belonging to financially healthy groups.     

Access to finance,working capital management and company value: Evidences from Brazilian companies listed on BM&FBOVESPA

In this research, we have analyzed the impact of financial leverage on the relationship between working capital and company value and how financial constraints on access to financing affect this relationship. In addition, we have analyzed the relationship between working capital and company value. Using a sample of Brazilian public companies listed on BM&FBOVESPA from 1995 through 2009, we found evidence for the following conclusions: an extra Real (R$) of investment in working capital is significantly less worth, on average, than an extra Real (R$) of investment in cash; and, on average, increasing the level of working capital at the beginning of a fiscal year reduces company value.     

房地产业发展对资本回报率的影响

采用资本租金公式法测算资本回报率,结果显示,房地产业发展拉低了资本回报率,2003年之后愈加明显。通过对房地产业投资和资本回报率关系的检验,发现房地产业投资对实体经济影响有限,短期拉动作用表现为年度贡献,长期内存在较大的波动效应;房地产业发展对资本回报率省际趋同效应的减弱日益显著。

Bankruptcy risk induced by career concerns of regulators

We introduce a model in which a regulator employs mechanism design to embed her human capital beta signal(s) in a firm’s capital structure. This can enhance her compensation at the firm, and the value of her contract with the firm in the form of an executive stock option. We prove that the agency cost of this revolving door behavior increases the firm’s financial leverage, bankruptcy risk, and affects estimation of firm value at risk (VaR).

Trust or bust: Growth effects of knowledge,human and social capital revisited

Social capital consists of trust, collective values, and shared norms. It helps society to work efficiently and, hence, promotes knowledge accumulation and growth. This paper identifies the contribution of social capital to differences in total factor productivity among European subnational regions, but, unlike other studies, it focuses on the effects of interregional differences in social capital. To do so, the paper employs a spatial Durbin model of a social-capital extended Cobb-Douglas production function. Our results suggest that transfers of knowledge might be secondary to the presence of collectivism and human capital in knowledge-generating regions. Although knowledge can cross boundaries, an absence of skills and trust limits local growth capacity. Our estimations also suggest the presence of gravity effects emanating from social and human capital in which some regions lose against others nearby that have more abundant social and human capital.     

重大突发公共卫生事件背景下企业捐赠对股价的影响——基于企业异质性的分组检验

以2020年沪深A股上市公司为样本,探讨在重大突发公共卫生事件暴发后企业捐赠对股票价格的影响,并分别从公司自身性质（产权性质、行业性质）、内部特征（内部控制质量、信息披露质量）、外部环境（产品市场竞争、所在地区疫情严重程度）三个维度研究捐赠发挥的作用效果是否会因企业异质性而存在显著差异。实证结果显示,在重大突发公共卫生事件背景下,企业捐赠对股票价格有显著正向影响。进一步研究发现,此关系会受到企业异质性的影响。具体而言,国有企业、受疫情负面影响严重行业的企业、内部控制质量低的企业、信息披露质量低的企业、疫情严重地区所在企业、产品市场竞争度高的企业,捐赠对股价的提升作用不显著。
