We investigate how changes in political relations between Europe and China affect the oil market. When political relations improve, we find a significant increase in oil demand and prices, accompanied by a decrease in market uncertainty. However, the effects on oil supply and inventory are minimal. Additionally, we compute the forecast error variance decomposition and construct the counterfactual evolution of oil variables in the absence of the impacts of political relation shocks. We find that shifts in Sino–European political relations contribute more significantly to variations in oil market uncertainty than to other oil variables. Finally, we augment the vector autoregression model by incorporating the Sino–US political relationship index. Our findings reveal that this augmentation significantly changes the impacts.
我们研究了中欧政治关系的变化如何影响石油市场。我们发现,当政治关系改善时,石油需求和价格会显著上升,同时市场的不确定性也会下降。然而,对石油供应和库存的影响微乎其微。此外,我们还计算了预测误差方差分解,并构建了在没有政治关系冲击影响的情况下石油变量的反事实演变。我们发现,与其他石油变量相比,中欧政治关系的变化对石油市场不确定性变化的影响更大。最后,我们在向量自回归模型中加入了中美政治关系指数。我们的研究结果表明,这种扩展极大地改变了影响。

This study examines the potential of institutional investor networks in mitigating horizontal agency conflicts, addressing the gap in the regulatory role of institutional investors in concentrated equity markets. Using data on Chinese listed companies from 2007 to 2020, we employ the multiplex network method to investigate the impact of institutional investor networks on earnings management. Our findings reveal a significant negative correlation between institutional investor networks and earnings management. The mechanism analysis indicates that institutional investor networks primarily exert governance through the exit threat rather than through direct intervention and information dissemination. Collectively, our findings elucidate the important role of institutional investors in corporate governance and promote the application of multiplex network theory to the financial field.
本研究探讨了机构投资者网络在缓解横向代理冲突方面的潜力,弥补了机构投资者在股权集中市场中监管作用方面的空白。我们利用 2007 年至 2020 年的中国上市公司数据,采用多重网络法研究了机构投资者网络对收益管理的影响。研究结果表明,机构投资者网络与收益管理之间存在明显的负相关关系。机制分析表明,机构投资者网络主要通过退出威胁而非直接干预和信息传播来实施治理。总之,我们的研究结果阐明了机构投资者在公司治理中的重要作用,促进了多重网络理论在金融领域的应用。

Cost stickiness is common in enterprise production and can significantly affect internal resource allocation. Past studies suggest that cost stickiness is more prominent in state-owned enterprises (SOEs). However, these studies have not addressed the impact of state-owned capital (SOC) on the cost stickiness of private enterprises. This study examined the effect of SOC on labor cost stickiness in private firms, employing data from China's private listed firms from 2010 to 2019. Empirical results show that SOC participation in private firms concurrently increased adjustment costs and decreased financing constraints. SOC also significantly exacerbated labor cost stickiness. This relationship was more evident among ordinary employees, competitive industries, and China's central and western regions. The findings demonstrate that SOC participation can harm corporate productivity in the short term but can benefit corporate innovation in the long term.
成本粘性在企业生产中很常见,会严重影响内部资源配置。以往的研究表明,成本粘性在国有企业中更为突出。然而,这些研究并未涉及国有资本(SOC)对民营企业成本粘性的影响。本研究采用 2010 年至 2019 年中国民营上市公司的数据,考察了国有资本对民营企业劳动力成本粘性的影响。实证结果表明,民营企业参与SOC同时增加了调整成本,降低了融资约束。SOC还明显加剧了劳动力成本粘性。这种关系在普通员工、竞争性行业和中国中西部地区更为明显。研究结果表明,参与国有企业在短期内会损害企业生产率,但从长期来看却有利于企业创新。

Global warming poses a serious and acute threat to our planet. However, negotiations over the allocation of permissible carbon emissions often lead to conflicts of interest between developed and developing countries. Developing countries claim that global warming results from long-term pollution emissions by developed countries, while developed countries demand that developing countries should make adequate efforts to reduce carbon emissions. Both developed and developing countries generally agree that stricter emission limits will strain their economies due to the associated extra abatement costs. Using a two-country model with wealth preferences, we find that the impacts of a country's emission limit on real consumption and pollution emissions in both countries vary depending on the combination of their business situations. If both countries achieve full employment, one country's stricter emission limit decreases real consumption in both, as expected. However, if one country faces aggregate demand stagnation while the other achieves full employment, a stricter emission limit imposed by the stagnant country increases real consumption in both countries.
全球变暖对我们的地球构成了严重而尖锐的威胁。然而,关于允许碳排放量分配的谈判常常导致发达国家和发展中国家之间的利益冲突。发展中国家声称全球变暖是发达国家长期排放污染造成的,而发达国家则要求发展中国家做出足够的努力减少碳排放。发达国家和发展中国家普遍认为,由于相关的额外减排成本,更严格的排放限制将给其经济带来压力。通过使用具有财富偏好的两国模型,我们发现一国的排放限制对两国实际消费和污染排放的影响因其商业状况的组合而异。如果两国都实现了充分就业,一国更严格的排放限制就会减少两国的实际消费,这是意料之中的。但是,如果一个国家面临总需求停滞,而另一个国家实现了充分就业,则停滞国实施更严格的排放限制会增加两国的实际消费。

This paper examines how inflation reacts depending on whether a supply (cost) or demand (markup) shock occurs. Despite their importance, the behaviour of markups remains an open empirical question in the literature. We use data for the US over the 1948q1-2019q3 period, decompose the price index to markups and costs, and employ a small-scale DSGE model to extract identifying size conditions for the coefficient estimates. These are then used in a Markov-switching VAR (MS-VAR) with fixed transition probabilities using an updating step. The empirical exercise shows that three different regimes exist (expansionary, contractionary, supply shock), while the Generalized Impulse Response Functions document that markups appear to be countercyclical and marginal costs are procyclical across all regimes. As such, inflation's reaction to a shock can be less volatile than expected depending on the regime. In addition, larger shocks have a lower and less persistent effect on inflation, because they are more easily identifiable, allowing corrective action to be taken.
本文探讨了通胀在供应(成本)或需求(加价)冲击下的反应。尽管加价非常重要,但其行为仍是文献中一个未解决的实证问题。我们使用美国 1948q1-2019q3 期间的数据,将价格指数分解为加价和成本,并采用一个小型 DSGE 模型来提取系数估计值的识别大小条件。然后将这些条件用于马尔可夫转换 VAR(MS-VAR),该 VAR 采用更新步骤,具有固定的转换概率。实证研究表明,存在三种不同的体制(扩张型、收缩型、供给冲击型),而广义脉冲响应函数表明,在所有体制中,加价似乎是反周期的,而边际成本是顺周期的。因此,通货膨胀对冲击的反应可能比预期的波动要小,这取决于不同的制度。此外,较大的冲击对通货膨胀的影响较小,持续性也较弱,因为它们更容易识别,从而可以采取纠正措施。

The impact of late payments on SMEs’ access to finance: Evidence from credit rationing and loan terms 逾期付款对中小企业获得融资的影响:来自信贷配给和贷款条件的证据

Late payments represent a significant threat to the financial resilience of European SMEs, with wide-reaching implications. While existing literature highlights the detrimental impact of late payments on SME liquidity and insolvency risk, the specific effects on credit availability and loan terms remain underexplored. Using unique firm-level data from 11 European countries over the period 2019–2023, we examine how late payments impact SMEs’ access to finance. We document that SMEs experiencing frequent or occasional late payments face difficulties in accessing finance. The primary mechanism is credit rationing, as banks potentially view cash flow uncertainty as an increased risk, prompting them to restrict lending. The increased risks perceived by banks translate into less favorable loan conditions for SMEs facing late payments, such as higher interest rates and smaller loan amounts. These findings highlight the importance of strengthening and enforcing the Late Payments Directive to address the persistent issue of late payments.
逾期付款对欧洲中小企业的财务恢复能力构成重大威胁,影响深远。虽然现有文献强调了逾期付款对中小企业流动性和破产风险的不利影响,但对信贷可用性和贷款条件的具体影响仍未得到充分探讨。我们利用 11 个欧洲国家 2019-2023 年期间独特的企业级数据,研究了逾期付款如何影响中小企业获得融资。我们发现,经常或偶尔逾期付款的中小企业在获得融资方面面临困难。主要机制是信贷配给,因为银行可能会将现金流的不确定性视为风险增加,从而限制贷款。银行认为风险的增加转化为对面临逾期付款的中小企业不太有利的贷款条件,如较高的利率和较小的贷款额度。这些研究结果凸显了加强和执行《逾期付款指令》以解决长期存在的逾期付款问题的重要性。

Industrial policy persistence and local economic performance: The role of subsidy allocation in China 产业政策的持续性与地方经济表现:中国补贴分配的作用

The persistence of economic policies is crucial for their effectiveness and economic outcomes. However, debates on industrial policy effectiveness have primarily focused on policy tools and target sectors, with little attention given to policy persistence. This paper addresses this gap by evaluating how policy persistence during subsidy implementation affects policy effectiveness. We measure policy persistence using cosine similarity between vectors reflecting the cross-industry distribution of subsidies over consecutive years and instrument it with the occurrence of abrupt public safety incidents. Our results reveal a significantly positive effect of subsidy allocation persistence on local economic performance. This effect is stronger when local governments are influential or industries need consistent government support and weaker when policy changes are more predictable or local officials are less prone to decision-making mistakes. We further provide micro-level evidence showing that the persistence of industrial policies impacts local economic performance by influencing the activities of local businesses.
经济政策的持续性对其有效性和经济成果至关重要。然而,关于产业政策有效性的讨论主要集中在政策工具和目标部门上,很少关注政策的持续性。本文通过评估补贴实施过程中的政策持续性如何影响政策效果来弥补这一不足。我们使用反映连续几年补贴跨行业分布的向量之间的余弦相似度来衡量政策的持续性,并用突发公共安全事件的发生率作为衡量工具。我们的结果显示,补贴分配的持续性对地方经济绩效有明显的积极影响。当地方政府有影响力或产业需要政府的持续支持时,这种效应会更强;当政策变化更可预测或地方官员不易犯决策错误时,这种效应会更弱。我们进一步提供了微观层面的证据,表明产业政策的持续性会通过影响地方企业的活动来影响地方经济绩效。

Herein, we used Vector Autoregressive and Dynamic Stochastic General Equilibrium models to examine the relation between central government debt and stock bubbles in China. The empirical findings indicate a considerable negative correlation between central government debt and stock bubbles. The model's results also illustrate that the liquidity substitution effect mainly drives a negative linkage. When commercial banks hold government debt, the effect establishes a connection between central government debt and asset bubbles through commercial banks' balance sheets. Further analysis indicates that countercyclical fiscal policies impact the negative correlation between government debt and stock bubbles. The findings suggest that governments should regulate debt levels to manage asset bubbles.
在此,我们使用向量自回归模型和动态随机一般均衡模型来研究中国中央政府债务与股票泡沫之间的关系。实证研究结果表明,中央政府债务与股票泡沫之间存在显著的负相关关系。模型的结果还表明,流动性替代效应是负相关的主要驱动力。当商业银行持有政府债务时,该效应通过商业银行的资产负债表建立了中央政府债务与资产泡沫之间的联系。进一步的分析表明,反周期财政政策会影响政府债务与股票泡沫之间的负相关关系。研究结果表明,政府应调节债务水平以管理资产泡沫。

Nominal GDP growth targeting vs. Taylor rules in a model with financial frictions 金融摩擦模型中的名义 GDP 增长目标与泰勒规则
IF 4.2 2区 经济学 Q1 ECONOMICS Pub Date : 2024-09-29 DOI: 10.1016/j.econmod.2024.106900

Nominal GDP growth targeting has gained favor over the last few decades in monetary policy literature (e.g., Ireland 2020; Garín et al. 2016; Beckworth and Hendrickson 2020). Calibrated, small-scale New Keynesian DSGE models have supported the proposition that nominal GDP growth (NGDP growth) rate targeting will improve welfare as compared with alternative strategies such as inflation targeting and Taylor rules with standard parameter settings. This paper examines that proposition in the context of a medium-scale New Keynesian model having a financial sector with frictions. In that model, NGDP growth rate targeting does poorly as compared with the Optimal Taylor rule and a wide range of Taylor rule settings leading up to the Optimal (representative agent utility maximizing) Taylor rule. The presence of the financial sector reveals that not only is NGDP growth rate targeting the least successful among the alternative targets and rules in creating welfare in this model; NGDP growth rate targeting also creates dramatically higher volatility of the policy rate and most financial variables.
过去几十年来,名义 GDP 增长率目标制在货币政策文献中越来越受到青睐(例如,Ireland 2020;Garín 等人,2016 年;Beckworth 和 Hendrickson,2020 年)。经过校准的小规模新凯恩斯主义 DSGE 模型支持这样一种主张,即与通货膨胀目标制和泰勒规则等其他策略相比,名义 GDP 增长率目标制将提高福利水平。本文以一个中等规模的新凯恩斯主义模型为背景,探讨了这一命题。在该模型中,与最优泰勒规则以及最优(代表代理人效用最大化)泰勒规则之前的各种泰勒规则设置相比,NGDP 增长率目标制表现不佳。金融部门的存在表明,在该模型中,不仅 NGDP 增长率目标制在创造福利方面是其他目标和规则中最不成功的;NGDP 增长率目标制还会导致政策利率和大多数金融变量的波动性急剧上升。

How to effectively discipline related-party transactions has garnered widespread attention from both academia and practice. While extensive literature has examined the factors influencing related-party transactions, it has overlooked the impact of sanctions imposed on peers on the related-party transactions of other firms. Using panel data covering Chinese listed firms from 2002 to 2021, we find that sanctions imposed on peers have a deterrence effect on observing firms. Increasing the certainty or severity of sanctions significantly reduces related-party transactions in observing firms. Mechanism tests demonstrate that media coverage, industry competition, and social trust strengthen this deterrence effect. Further analysis suggests the deterrence effect of sanctions is primarily driven by indirect reputation effects. Additionally, we find that deterrence effect exists in both state-owned enterprises (SOEs) and non-SOEs. Our study sheds light on the efficacy of enforcement in the Chinese capital market and offers important implications for enhancing regulatory efficiency in emerging economies.
如何有效约束关联方交易已引起学术界和实务界的广泛关注。虽然大量文献研究了影响关联方交易的因素,但却忽视了对同业的制裁对其他公司关联方交易的影响。利用 2002 年至 2021 年中国上市公司的面板数据,我们发现对同行的制裁会对观察企业产生威慑效应。提高制裁的确定性或严厉程度会显著减少观察企业的关联方交易。机制检验表明,媒体报道、行业竞争和社会信任加强了这种威慑效应。进一步分析表明,制裁的威慑效应主要由间接声誉效应驱动。此外,我们还发现国有企业和非国有企业都存在威慑效应。我们的研究揭示了中国资本市场的执法效力,并为提高新兴经济体的监管效率提供了重要启示。
