Agricultural export competitiveness is shaped not only by a country's own production capacity and scale but also by developments in other countries, as improvements elsewhere may alter relative market positions through competition and spatial interdependence. Foreign Direct Investment (FDI) represents one important channel through which such cross-country externalities may arise. However, much of the existing country-specific literature overlooks spatial interdependencies among countries, particularly in the agricultural sector. This study examines the impact of aggregate FDI on agricultural export competitiveness across 52 African economies, explicitly accounting for spatial spillovers and cross-sectional dependence. Employing a Spatial Autoregressive (SAR) model, the analysis finds that FDI exerts a positive direct effect on a host country's agricultural export competitiveness, but does not find strong evidence of negative externalities of FDI on neighbouring or nearby countries. Any observed negative spatial effects are largely attributable to disparities in the scale of agricultural production rather than to FDI-related displacement. Furthermore, the analysis finds no evidence of heterogeneous FDI effects on agricultural export competitiveness between landlocked and coastal countries, nor across major African regional economic groupings relative to the Southern African Development Community (SADC), while countries outside these groupings exhibit significantly stronger FDI effects. These results suggest that strengthening agricultural export competitiveness in Africa should prioritise attracting FDI at both national and regional levels, as its positive domestic effects are not offset by statistically significant losses in neighbouring countries, while regional coordination remains essential for managing scale-driven spatial competition.
农业出口竞争力不仅取决于一国自身的生产能力和规模,还取决于其他国家的发展,因为其他地方的发展可能通过竞争和空间相互依存改变相对的市场地位。外国直接投资(FDI)是产生这种跨国外部性的一个重要渠道。然而,许多现有的针对具体国家的文献忽视了各国之间的空间相互依存关系,特别是在农业部门。本研究考察了52个非洲经济体的外商直接投资总额对农业出口竞争力的影响,明确考虑了空间溢出效应和横向依赖。采用空间自回归(SAR)模型分析发现,FDI对东道国的农业出口竞争力产生了积极的直接影响,但没有发现FDI对邻国或附近国家产生负外部性的有力证据。任何已观察到的负面空间效应主要归因于农业生产规模的差异,而不是与外国直接投资相关的流离失所。此外,分析发现没有证据表明外国直接投资对内陆和沿海国家之间的农业出口竞争力有异质影响,也没有证据表明非洲各主要区域经济集团对南部非洲发展共同体(SADC)的农业出口竞争力有异质影响,而这些集团以外的国家则表现出明显更强的外国直接投资影响。这些结果表明,加强非洲农业出口竞争力应优先在国家和区域层面吸引外国直接投资,因为其对国内的积极影响不会被邻国在统计上的重大损失所抵消,而区域协调对于管理规模驱动的空间竞争仍然至关重要。

The rapid rise of digital finance has become essential for firms seeking to ascend the global value chain (GVC). This paper investigates whether and how the development of city-level digital finance influences firms' span of production stages along the GVC. The results show that digital finance significantly expands firms' production stages, and the finding remains robust to multiple tests. Further mechanism analysis disclosures that digital finance realizes its positive impact by increasing firms' import upstreamness, alleviating external financial constraints, and enhancing innovation activities, which ultimately enable firms to occupy more stages in global production. Heterogeneity tests indicate that the effects vary systematically across firms of different sizes and ownership types.
数字金融的迅速崛起对于寻求提升全球价值链(GVC)的公司来说至关重要。本文研究了城市级数字金融的发展是否以及如何影响企业沿全球价值链的生产阶段跨度。结果表明,数字金融显著地扩展了企业的生产阶段,并且这一发现在多次检验中仍然是稳健的。进一步的机制分析表明,数字金融通过增加企业的上游进口、缓解外部资金约束和增强创新活动来实现其积极影响,最终使企业能够在全球生产中占据更多的阶段。异质性检验表明,在不同规模和所有权类型的公司中,这种影响存在系统性差异。

With the deepening of the marketization process of data elements, the financial value of data assets as a new type of collateral is increasingly prominent. However, their pledge financing practices still face multiple regulatory challenges under the legal positioning of "right pledge". This article takes the practice of data asset pledg financing in China as a mirror to systematically analyze the institutional barriers and operational risks that exist in the registration, value assessment, risk control, and disposal and realization of financial institutions. It reveals the structural failures of the existing regulatory system in terms of rule adaptability, regulatory boundary coordination, and regulatory technology. Based on this, this article proposes to construct a four in one hierarchical regulatory governance framework: at the legislative level, it is necessary to improve the data ownership registration system and evaluation standard system, clarify the legal attributes and registration publicity effectiveness of data assets as pledged property, and consolidate the foundation of rights; At the process supervision level, it is necessary to clarify that financial regulatory agencies are the main regulatory agencies, agree on data value adjustment and quality assurance clauses in financing contracts, establish core responsibilities for due diligence and continuous monitoring, and promote full process supervision of data pledge using regulatory sandbox technology; Default relief layer, establish mandatory management procedures for third-party data asset custody institutions; At the ecological level, establish a collaborative mechanism of "risk compensation + insurance protection" guided by the government and market participation, and improve the data asset trading market and disposal channels. Through legal improvement, institutional innovation, technological empowerment, and ecological co construction, we aim to promote the dynamic balance between the financialization of data elements and risk prevention and control, and assist in the high-quality development of the digital economy.
随着数据要素市场化进程的不断深入,数据资产作为一种新型抵押品的金融价值日益凸显。然而,在“权利质押”的法律定位下,它们的质押融资实践仍面临多重监管挑战。本文以中国数据资产质押融资实践为镜像,系统分析金融机构在注册、价值评估、风险控制、处置变现等方面存在的制度障碍和操作风险。揭示了现行监管制度在规则适应性、监管边界协调和监管技术等方面的结构性失灵。基于此,本文提出构建“四合一”层级监管治理框架:在立法层面,完善数据权属登记制度和评价标准体系,明确数据资产作为质押财产的法律属性和登记公示效力,夯实权利基础;在过程监管层面,要明确金融监管机构为主要监管机构,约定融资合同中的数据价值调整和质量保证条款,建立尽职调查和持续监测的核心责任,运用监管沙盒技术推进数据质押全过程监管;违约救济层,建立第三方数据资产托管机构强制性管理程序;在生态层面,建立政府引导、市场参与的“风险补偿+保险保障”协同机制,完善数据资产交易市场和处置渠道。通过法律完善、制度创新、技术赋能、生态共建,促进数据要素金融化与风险防控的动态平衡,助力数字经济高质量发展。

This study explores the dynamics of option trading on the EURO STOXX 50 and NASDAQ 100 indices, focusing on the distinct market behaviors, trading activities, and elasticity characteristics in the EU and US option markets. Utilizing a mixed effects panel regression model combined with the GJR-GARCH framework, we examine the influence of various factors on option pricing and investor strategies. Our findings reveal that the EU market exhibits a more conservative trading approach, with a balanced distribution of call options and a concentration of deep out-of-the-money put options. In contrast, the US market favors more speculative strategies, particularly around at-the-money options. The analysis indicates that US options demonstrate higher elasticity, reflecting a greater sensitivity to changes in the underlying assets, while the EU market shows higher trading activity and open interest. Additionally, we identify significant differences in leverage and open interest coefficients between the two markets, suggesting distinct trading behaviors and underlying market structures. This research enhances the understanding of option market dynamics, shedding light on the varying risk profiles and strategic preferences of investors in the EU and US markets.
本研究探讨了欧洲斯托克50指数和纳斯达克100指数期权交易的动态,重点关注欧盟和美国期权市场的不同市场行为、交易活动和弹性特征。本文运用混合效应面板回归模型结合GJR-GARCH框架,考察了各因素对期权定价和投资者策略的影响。我们的研究结果表明,欧盟市场表现出更为保守的交易方式,看涨期权的分布较为均衡,而超面值看跌期权则较为集中。相比之下,美国市场更倾向于投机策略,尤其是在平价期权方面。分析表明,美国期权表现出更高的弹性,反映出对标的资产变化的更大敏感性,而欧盟市场表现出更高的交易活动和未平仓合约。此外,我们发现两个市场之间的杠杆和未平仓合约系数存在显著差异,表明不同的交易行为和潜在的市场结构。本研究增强了对期权市场动态的理解,揭示了欧盟和美国市场投资者的不同风险概况和战略偏好。

As a vital instrument for stimulating consumption, the nighttime economy has emerged as a critical driver of high-quality economic development. This study examines the relationship between digital finance and the nighttime economy using panel data from 31 Chinese provinces between 2011 and 2023, employing the two-way fixed effect model and regression discontinuity design. The findings reveal that digital finance and its sub-dimensions significantly promote the development of the nighttime economy. Meanwhile, this impact shows significant positive spatial spillover effect. Financial attention across three distinct agents moderates the relationship between digital finance and the nighttime economy. Specifically, government financial regulation and corporate financial competition exhibit inhibitory effects, whereas public financial literacy exhibits a promotive effect. The relationship exhibits heterogeneity across provinces with varying geographical locations, levels of financial human resources, and periods preceding and following key financial policy implementations. Moreover, the impact of digital finance on the nighttime economy exhibits a significant shift in 2017, related to G20 High-Level Principles for Digital Financial Inclusion. This study deepens the mechanistic understanding of the relationship between digital finance and the nighttime economy, providing valuable empirical evidence to inform governmental financial policymaking.
夜间经济作为拉动消费的重要手段,已成为推动经济高质量发展的重要力量。本文利用2011 - 2023年中国31个省份的面板数据,采用双向固定效应模型和回归不连续设计,检验了数字金融与夜间经济的关系。研究发现,数字金融及其子维度显著促进了夜间经济的发展。同时,这种影响表现出显著的正空间溢出效应。三个不同主体的金融关注调节了数字金融与夜间经济之间的关系。具体而言,政府金融监管和企业金融竞争表现出抑制作用,而公众金融素养表现出促进作用。这种关系在不同地理位置、不同财政人力资源水平、不同关键财政政策实施前后时期的省份之间表现出异质性。此外,数字金融对夜间经济的影响在2017年出现了重大转变,这与G20数字金融包容性高级原则有关。本研究深化了对数字金融与夜间经济关系的机制理解,为政府金融决策提供了有价值的经验证据。

We study the nexus between institutional quality and domestic bond market development. Using World Bank data, we undertake a comprehensive search for associations between various institutional quality indicators and domestic bond market development. We find that markers of rule of law, regulatory quality, control of corruption, government effectiveness, political stability and absence of violence/terrorism, and voice and accountability are all predictive of bond market growth in the longer term. Although the direction of association between institutional quality indicators and bond market development remains broadly consistent across models, the magnitude and statistical significance vary across dimensions. In particular, rule of law and political stability consistently show stronger and statistically significant effects in fixed-effects and five-year lagged models. Our econometric set-up ensures that endogeneity owing to reverse causality is avoided, enhancing the likelihood that these associations are causal. We provide further insights as to whether the impact of institutional quality is direct or indirect via mediating analysis. The indirect impacts of institutional quality through broader economic variables are stronger than the direct impacts.
本文研究了制度质量与国内债券市场发展的关系。利用世界银行的数据,我们对各种制度质量指标与国内债券市场发展之间的关系进行了全面的研究。我们发现,法治、监管质量、腐败控制、政府效率、政治稳定和没有暴力/恐怖主义、话语权和问责制等指标都是债券市场长期增长的预测指标。虽然机构质量指标与债券市场发展之间的关联方向在各个模型中大致保持一致,但其大小和统计显著性在不同维度上有所不同。特别是,在固定效应和五年滞后模型中,法治和政治稳定始终显示出更强的、统计上显著的影响。我们的计量经济学设置确保避免了由于反向因果关系而产生的内生性,从而增强了这些关联是因果关系的可能性。通过中介分析,我们进一步了解了制度质量的影响是直接的还是间接的。制度质量通过更广泛的经济变量产生的间接影响强于直接影响。

Bank branch efficiency with a Bayesian lens on technological heterogeneity 技术异质性的贝叶斯视角下的银行分支效率

Although technological heterogeneity between banks has been previously considered in the literature, less attention has been given to technological heterogeneity between branches of the same bank. This paper analyses the efficiency, returns to scale (RTS) and productivity growth of bank branches considering a stochastic frontier approach that includes unobserved technological heterogeneity between branches and time-varying efficiencies. Specifically, we propose a random parameters stochastic distance frontier model that includes multiple inputs and outputs. We assume a translog output distance function estimated in an objective Bayesian framework. The empirical analysis was carried out using data from 2011 to 2017 from a large Spanish commercial bank with 122 branches. The random parameters model adds, in general, flexibility to the estimates, allowing for the identification of periods with more extreme efficiencies, both high and low, which the fixed parameters model is unable to capture. The random parameters model also detects an increase in efficiency over time that the fixed parameters model fails to identify. The differences between the two models are sufficient to drastically modify the efficiency ranking of the branches. The random parameters model also found greater dispersion than the fixed parameters model in estimation of the RTS and productivity growth.
虽然以前的文献中已经考虑了银行之间的技术异质性,但对同一银行分支机构之间的技术异质性的关注较少。本文采用随机前沿方法分析了银行分支机构的效率、规模回报(RTS)和生产率增长,该方法考虑了未观察到的分支机构之间的技术异质性和时变效率。具体来说,我们提出了一个包含多个输入和输出的随机参数随机距离前沿模型。我们假设一个在客观贝叶斯框架中估计的超对数输出距离函数。实证分析使用了一家拥有122家分行的西班牙大型商业银行2011年至2017年的数据。一般来说,随机参数模型增加了估计的灵活性,允许识别具有更极端效率的时期,包括高效率和低效率,这是固定参数模型无法捕获的。随机参数模型还检测到固定参数模型无法识别的效率随时间的增加。这两种模型之间的差异足以极大地改变分支机构的效率排名。随机参数模型在RTS和生产率增长的估计上也比固定参数模型有更大的离散性。

We examine the short- and long-term market reactions toward S&P 500 index constituents surrounding a pivotal event on May 26, 2021, when Engine No. 1, an environmental activist investment firm, successfully secured board seats at ExxonMobil, a leading non-renewable energy producer. Our analysis reveals a significant positive market response, particularly for firms with higher environmental and emission-related concerns immediately following the event and over an extended horizon. These findings indicate that actions by environmental activist shareholders can drive favorable equity market outcomes, especially for firms facing substantial environmental challenges. By drawing on and empirically testing stakeholder theory, efficient market theory, and prospect theory, we propose that the observed positive reactions stem from market anticipation of reduced environmental and emission risks due to the influence of environmentally conscious investors. This study highlights the transformative role of activist-driven governance in altering market perceptions of environmentally sensitive firms and their prospects.
我们研究了围绕2021年5月26日一个关键事件对标准普尔500指数成分股的短期和长期市场反应,当时环境维权投资公司Engine No. 1成功获得了埃克森美孚(一家领先的不可再生能源生产商)的董事会席位。我们的分析显示,市场反应非常积极,特别是对环境和排放相关问题高度关注的公司,在事件发生后不久以及在较长一段时间内。这些发现表明,环保激进股东的行动可以推动有利的股票市场结果,特别是对于面临重大环境挑战的公司。通过借鉴利益相关者理论、有效市场理论和前景理论并进行实证检验,我们提出观察到的积极反应源于市场预期环境和排放风险由于环保意识投资者的影响而降低。本研究强调了激进主义者驱动的治理在改变市场对环境敏感公司及其前景的看法方面的变革作用。

Using the establishment of open government data platforms as a quasi-natural experiment, we employ the staggered difference-in-differences model to identify the causal impact of open government data on entrepreneurship. The results show that open government data significantly promotes entrepreneurship. Mitigating institutional friction and enhancing financing accessibility are two plausible underlying mechanisms. The positive effect is more pronounced in service industries, general-administration cities, and non-resource-dependent, low-digital-infrastructure, and low-marketization regions. Furthermore, our study indicates that enhancing data quality, specifically platform usability and data comprehensiveness, is critical for maximizing entrepreneurial benefits. Finally, our study confirms that entrepreneurship induced by open government data contributes to urban economic growth. Our findings offer novel insights into how the government data openness shapes entrepreneurship.
以政府开放数据平台的建立为准自然实验,采用交错差中差模型识别政府开放数据对创业的因果影响。结果表明,政府数据开放对创业有显著的促进作用。缓解制度摩擦和提高融资可及性是两个看似合理的潜在机制。在服务业、综合型城市和非资源依赖型、基础设施数字化程度低、市场化程度低的地区,这种积极效应更为明显。此外,我们的研究表明,提高数据质量,特别是平台可用性和数据全面性,对于企业利益最大化至关重要。最后,我们的研究证实了政府开放数据诱导的企业家精神对城市经济增长的贡献。我们的研究结果对政府数据开放如何影响企业家精神提供了新的见解。

The perception of uncertainty surrounding the monetary policy stance of the central bank may disrupt the traditional policy transmission mechanism. This study constructs a news-based monetary policy uncertainty index (MPU) for India and evaluates the role of MPU in monetary policy transmission to financial markets. Results from Interacted and State-Dependent Local Projection models suggest that MPU impedes the policy transmission mechanism. Under monetary tightening, MPU amplifies long term bond yields, reduces 3-month T-bill yields, moderates the recovery of stock prices after exacerbating the initial fall, and causes a longer period of currency depreciation. These findings suggest that MPU has asymmetric effects on the monetary transmission process and a low uncertainty state is conducive for effective transmission of monetary policy to financial markets. The results are shown to be robust to an alternative measure of MPU. The study provides useful insights for monetary authorities on the need for effective communication and forward guidance in managing expectations.
围绕央行货币政策立场的不确定性感知可能会扰乱传统的政策传导机制。本文构建了基于新闻的印度货币政策不确定性指数(MPU),并评估了MPU在货币政策向金融市场传导中的作用。相互作用和状态依赖的局部预测模型的结果表明,MPU阻碍了政策传导机制。在货币紧缩的情况下,MPU放大了长期债券收益率,降低了3个月国库券收益率,在加剧了最初的下跌后缓和了股价的回升,并导致了更长时间的货币贬值。这些结果表明,MPU对货币政策传导过程具有不对称效应,低不确定性状态有利于货币政策向金融市场的有效传导。结果表明对MPU的另一种测量方法具有鲁棒性。这项研究为货币当局提供了有用的见解,说明在管理预期方面需要有效的沟通和前瞻性指导。
