This study investigates the impact of product market power on stock liquidity against the backdrop of rising market power and global financial market integration. It also explores the nonlinearities associated with this relationship. In addition, we examine the interaction of firm size and leverage with market power and how it shapes the market power–stock liquidity relationship. The study uses a firm-year panel of 865 NSE-listed firms from India over the period 2011–2021, and employs panel regression techniques to analyze these. Product market power is measured using price-cost markups, and stock liquidity is captured using the inverse of the illiquidity ratio and share turnover. The analysis indicates an inverted U-shaped relationship between product market power and stock liquidity. Results also highlight the role of informational asymmetries and strategic opacity in this relationship. Further, the asymmetric role of leverage and firm size in the influence of product market power on stock liquidity is confirmed. The impact of product market power on stock liquidity and the moderating/mediating influence of informational asymmetries and leverage can have significant implications for the design of policies by the firms and authorities that monitor the competitiveness of markets.

本研究探讨在市场力上升及全球金融市场整合的背景下，产品市场力对股票流动性的影响。它还探讨了与这种关系相关的非线性。此外，我们研究了企业规模和杠杆与市场力量的相互作用，以及它如何塑造市场权力-股票流动性关系。该研究使用了2011-2021年期间印度865家nse上市公司的公司年面板，并采用面板回归技术对其进行分析。产品市场力量是用价格成本加成来衡量的，股票流动性是用非流动性比率和股票周转率的倒数来衡量的。分析表明，产品市场支配力与股票流动性呈倒u型关系。结果还强调了信息不对称和战略不透明在这种关系中的作用。进一步证实了杠杆和企业规模在产品市场支配力对股票流动性影响中的不对称作用。产品市场力量对股票流动性的影响以及信息不对称和杠杆的调节/中介影响，对监测市场竞争力的公司和当局设计政策具有重大影响。

This study examines the macroeconomic impact of policy uncertainty in climate decision-making. It employs data mining to 23 Portuguese news sources to construct a novel monthly Climate Policy Uncertainty (CPU) series, which is then used in a Structural Vector Autoregression (SVAR) model to analyze its macroeconomic effects. These responses collectively reveal significant economic restructuring in response to climate policy uncertainty. The combination of reduced industrial production and increased unemployment suggests substantial supply-side adjustment costs during the transition. However, the positive stock market response indicates that financial markets view these changes as ultimately beneficial for certain sectors, particularly those aligned with environmental sustainability.

本研究考察了政策不确定性对气候决策的宏观经济影响。它利用23个葡萄牙新闻来源的数据挖掘来构建一个新颖的月度气候政策不确定性（CPU）系列，然后将其用于结构向量自回归（SVAR）模型来分析其宏观经济影响。这些反应共同揭示了为应对气候政策的不确定性而进行的重大经济调整。工业生产减少和失业增加的结合表明，在转型期间，供应方面的调整成本很高。然而，股市的积极反应表明，金融市场认为这些变化最终有利于某些部门，特别是那些与环境可持续性相一致的部门。

The limited number of studies that have assessed the impact of debt on income inequality have used data at the aggregate country level. In this paper, when we use aggregate data from the U.S., we do not find much of a significant effect. However, when we use data from each of the states in the U.S., we find short-run (but not long-run) effects. By then assuming that the effects of debt on GINI (inequality measure) could be asymmetric, we employ a nonlinear ARDL modeling approach and find that in the long run, reducing national debt in the U.S. could reduce income inequality in most states.

数量有限的评估债务对收入不平等影响的研究使用的是国家合计一级的数据。在本文中，当我们使用来自美国的汇总数据时，我们没有发现太大的显著影响。然而，当我们使用来自美国每个州的数据时，我们发现了短期（而不是长期）的影响。然后假设债务对GINI（不平等衡量）的影响可能是不对称的，我们采用非线性ARDL建模方法，发现从长远来看，减少美国的国债可以减少大多数州的收入不平等。

This study investigates the system-wide consequences of rising geopolitical risks (GPR) on global energy trade, emphasizing asymmetric vulnerabilities between emerging market economies (EMEs) and advanced economies (AEs)—a critical gap in existing scholarship. Combining autoregressive distributed lag (ARDL) modeling and impulse response analyses on 55 countries (1990–2023), we assess how geopolitical tensions disrupt energy trade dynamics, accounting for global volatility and domestic economic conditions. Our findings uncover marked asymmetries: while geopolitical risks persistently suppress energy trade, with long-term effects outweighing transient shocks, EMEs are disproportionately destabilized due to their heavy reliance on energy exports and weaker institutional capacity. AEs, conversely, demonstrate greater resilience through diversified economies, strategic reserves, and policy flexibility, though post-2008 geopolitical fragmentation and financial instability intensify disruptions across all economies. Impulse response simulations reveal that geopolitical shocks trigger sharper declines in energy trade flows for EMEs, with steeper and more prolonged contractions than AEs. Compounding these unequal burdens, escalating trade taxes strain EMEs’ fiscal stability and energy security, whereas AEs deploy fiscal buffers to cushion shocks. By exposing how geopolitical risks cascade through energy systems, the study underscores the urgency of multilateral cooperation to address structurally embedded asymmetries, particularly the fragility of EMEs in global energy frameworks.

本研究探讨了不断上升的地缘政治风险（GPR）对全球能源贸易的全系统后果，强调了新兴市场经济体（eme）和发达经济体（ae）之间的不对称脆弱性——这是现有学术研究中的一个重大缺口。结合自回归分布滞后（ARDL）模型和对55个国家（1990-2023）的脉冲响应分析，我们评估了地缘政治紧张局势如何破坏能源贸易动态，考虑到全球波动和国内经济状况。我们的研究结果揭示了明显的不对称性：地缘政治风险持续抑制能源贸易，其长期影响超过短暂冲击，而新兴市场由于严重依赖能源出口和较弱的制度能力而不成比例地不稳定。相反，发达国家通过经济多元化、战略储备和政策灵活性表现出更强的抵御能力，尽管2008年后地缘政治碎片化和金融不稳定加剧了所有经济体的破坏。脉冲响应模拟显示，地缘政治冲击引发新兴市场国家能源贸易流量急剧下降，收缩幅度更大、持续时间更长。不断升级的贸易税加剧了这些不平等负担，给新兴市场国家的财政稳定和能源安全带来压力，而发达国家则利用财政缓冲来缓冲冲击。通过揭示地缘政治风险如何在能源系统中层叠蔓延，该研究强调了多边合作解决结构性不对称的紧迫性，特别是新兴市场在全球能源框架中的脆弱性。

This paper investigates the impact of geopolitical risk (GPR) and global uncertainty (WUI) on energy prices across 185 economies from 1980 to 2023, while accounting for the role of exchange rate regimes. Using a panel fixed-effects model and a panel SVAR framework, we examine whether uncertainty shocks translate into energy price inflation and how exchange rate regimes influence these dynamics. The results indicate that geopolitical risk and global uncertainty have significant effects on energy prices, with stronger price reactions under flexible exchange rate regimes. We further decompose the effects by country classification, revealing that oil-exporting economies and emerging markets exhibit distinct responses. Our findings highlight the importance of exchange rate policies in mitigating uncertainty-driven energy price volatility. The paper contributes to the literature by providing a global empirical perspective on uncertainty-energy price interactions, with relevant implications for policymakers managing exchange rate regimes and energy market stability.

本文研究了1980年至2023年间地缘政治风险（GPR）和全球不确定性（WUI）对185个经济体能源价格的影响，同时考虑了汇率制度的作用。使用面板固定效应模型和面板SVAR框架，我们研究了不确定性冲击是否转化为能源价格通胀，以及汇率制度如何影响这些动态。结果表明，地缘政治风险和全球不确定性对能源价格有显著影响，弹性汇率制度下的价格反应更强。我们进一步按国家分类分解影响，发现石油出口经济体和新兴市场表现出不同的反应。我们的研究结果强调了汇率政策在缓解不确定性驱动的能源价格波动方面的重要性。本文通过提供不确定性-能源价格相互作用的全球经验视角，为政策制定者管理汇率制度和能源市场稳定提供了相关启示，从而对文献做出了贡献。

The far-reaching impacts of the euro's introduction in 1999 have reshaped Europe's monetary landscape, extending integration even to non-euro economies. The primary aim of this paper is to examine whether the non-euro European economies are monetarily linked to the Euro Area. Using economic indicators from nine European countries, alongside the Eurozone, and employing SVECM models, this research assesses the degree of monetary integration. The empirical findings strongly indicate that the economies of Poland, Romania, Sweden and Norway have been positively bound and highly integrated with the Eurozone since the euro's launch. Moreover, the economies of Czechia and Hungary have demonstrated a steady and increasing level of monetary integration with the Eurozone over time. In contrast, the economies of Iceland, Switzerland, and the UK exhibit monetary divergence from the Eurozone. Based on these findings, the research proposes that Poland and Romania may need to explore the possibility of joining the Euro Area, while Norway and Sweden may (re)consider their stance on potential EU or EMU membership, respectively. The results underscore that the creation of the Eurozone and the circulation of the euro have played a significant role in facilitating and advancing monetary integration across Europe.

1999年欧元的引入产生了深远的影响，重塑了欧洲的货币格局，甚至将一体化扩展到了非欧元经济体。本文的主要目的是考察非欧元区的欧洲经济体是否与欧元区有货币联系。本研究使用来自9个欧洲国家和欧元区的经济指标，并采用SVECM模型来评估货币一体化程度。实证研究结果强烈表明，自欧元启动以来，波兰、罗马尼亚、瑞典和挪威的经济与欧元区有着积极的联系和高度的融合。此外，随着时间的推移，捷克和匈牙利的经济与欧元区的货币一体化水平稳步上升。相比之下，冰岛、瑞士和英国的经济表现出与欧元区的货币差异。基于这些发现，研究建议波兰和罗马尼亚可能需要探索加入欧元区的可能性，而挪威和瑞典可能（重新）考虑他们对潜在的欧盟或欧洲货币联盟成员的立场。结果强调，欧元区的创建和欧元的流通在促进和推进整个欧洲的货币一体化方面发挥了重要作用。

Is fiscal countercyclicality growth enhancing? Evidence from developing countries over the period 1990–2019 财政逆周期增长增强了吗？来自发展中国家1990-2019年的证据

The objective of this paper is to analyze the time-varying effect of improving fiscal countercyclicality on growth for a sample of 35 developing countries over the period 1990–2019. By estimating a time-varying coefficient for fiscal countercyclicality, incorporated as a variable in a panel model, we first examine how the public debt ratio and electoral motivations influence the ability to adopt countercyclical policies. Secondly, we show that greater countercyclicality positively affects economic growth and contributes to reducing the output gap, particularly during recessions, by channeling production towards its potential path. Finally, our findings are confirmed across two sub-samples, demonstrating a positive effect on growth before the 2008 crisis and a reduction in the output gap both before and after the crisis. The effect is stronger in the sub-sample characterized by high income, low debt, and strong control of corruption, suggesting that the effectiveness of countercyclical policies depends on macroeconomic and institutional factors.

Countercyclical fiscal management should therefore be given greater consideration by fiscal policymakers in developing countries, both upstream and downstream.

本文的目的是分析1990年至2019年期间35个发展中国家改善财政逆周期性对经济增长的时变效应。通过估计财政逆周期的时变系数，并将其作为一个变量纳入面板模型，我们首先研究了公共债务比率和选举动机如何影响采取逆周期政策的能力。其次，我们表明，更大的反周期效应会对经济增长产生积极影响，并有助于减少产出缺口，特别是在经济衰退期间，通过将生产引导至潜在路径。最后，我们的研究结果在两个子样本中得到了证实，表明在2008年危机前对经济增长有积极影响，在危机前后都缩小了产出缺口。在高收入、低债务和严格控制腐败的子样本中，这种效应更强，这表明逆周期政策的有效性取决于宏观经济和制度因素。因此，发展中国家上下游的财政政策制定者都应更多地考虑反周期财政管理。

Does economic convergence diverge along the income distribution? Evidence from a decile-based analysis 经济趋同是否沿着收入分配而分化？来自十分位数分析的证据

Q1 Economics, Econometrics and Finance

Journal of Economic Asymmetries

Pub Date : 2025-05-02 DOI: 10.1016/j.jeca.2025.e00419

Marco Amendola

This paper contributes to the literature on economic convergence by exploring an overlooked aspect: the potential heterogeneity of convergence processes across different segments of the income distribution. While previous analyses have typically focused on per capita income or GDP, this study adopts a more granular perspective by examining convergence at per capita income deciles. Drawing on data from 25 countries spanning 1980 to 2019, the analysis reveals a distinct pattern of divergence in the convergence process: higher-income deciles exhibit stronger convergence than lower-income ones, with this divergence widening in recent decades. These findings highlight the uneven nature of economic convergence, demonstrating that reducing cross-country income disparities is especially challenging for low-income groups — those most in need of improved well-being and economic catch-up.

本文通过探索一个被忽视的方面来为经济趋同的文献做出贡献：在收入分配的不同部分之间，趋同过程的潜在异质性。虽然以前的分析通常集中在人均收入或GDP上，但这项研究通过考察人均收入十分位数的趋同，采用了更细致的视角。根据1980年至2019年25个国家的数据，该分析揭示了趋同过程中的一种明显的差异模式：高收入十分位数比低收入十分位数表现出更强的趋同，近几十年来这种差异不断扩大。这些发现突出了经济趋同的不平衡性质，表明减少跨国收入差距对低收入群体尤其具有挑战性，这些群体最需要改善福祉和经济赶超。

Collapsing bubbles in the prices of cryptocurrencies 加密货币价格泡沫破裂

This paper investigates the existence of bubbles in the daily prices of the most popular cryptocurrencies, Bitcoin (BTC), Ether (ETH), and Ripple (XRP), employing the recursive methods of Phillips et al. (2015) and Phillips et al. (2011) for testing and date-stamping episodes of exuberant behaviour over a period spanning seven years (2018–2024), including the COVID-19 pandemic crisis (2020–2021). The critical values of the tests are computed through the composite wild bootstrap technique by Phillips and Shi (2020) to make them robust to time-varying unconditional heteroscedasticity and the multiplicity issue in recursive tests. Results indicate that the prices of the most popular cryptocurrencies traded on decentralized ledgers, BTC and ETH, exhibited multiple episodes of exuberant behaviour, unambiguously for BTC and depending on the tests for ETH. Bubbles detected in the prices of BTC were due to the halving of the crypto, to market exuberance and to the pandemic crisis; bubbles detected on ETH prices were due to the launch of NFTs on the Ethereum blockchain, and to the change in investors’ expectations (from exuberant to pessimistic); the change in the stance of monetary policy burst the bubbles of BTC and ETH prices in 2024. No test supports the exuberance of XRP that is traded on a centralized ledger; weekly data confirm the absence of multiple bubbles. By looking at the presence of bubbles in these different digital ecosystems, we also consider how the technological differences can impact, possibly asymmetrically, bubbles' formation.

本文研究了最流行的加密货币比特币（BTC）、以太币（ETH）和瑞波币（XRP）每日价格中泡沫的存在，采用了Phillips等人（2015）和Phillips等人（2011）的递归方法，对七年（2018-2024）期间(包括2019冠状病毒病大流行危机（2020-2021）的繁荣行为进行了测试和日期戳。检验的临界值由Phillips和Shi（2020）通过复合野生自举技术计算，使其对时变无条件异方差和递归检验中的多重性问题具有鲁棒性。结果表明，在去中心化分类账（BTC和ETH）上交易的最受欢迎的加密货币的价格表现出多次旺盛的行为，这显然是针对BTC的，取决于对ETH的测试。在比特币价格中发现的泡沫是由于加密货币减半、市场繁荣和流行病危机；ETH价格的泡沫是由于在以太坊区块链上推出了nft，以及投资者预期的变化（从乐观到悲观）；2024年，货币政策立场的变化打破了比特币和以太坊价格的泡沫。没有测试支持在集中分类账上交易的瑞波币的繁荣；每周数据证实了多重泡沫的存在。通过观察这些不同数字生态系统中泡沫的存在，我们也考虑了技术差异如何影响泡沫的形成，可能是不对称的。

By looking at the presence of bubbles in these different digital ecosystems, we also consider how the technological differences can impact, possibly asymmetrically, bubbles' formation.</div></div>","PeriodicalId":38259,"journal":{"name":"Journal of Economic Asymmetries","volume":"31 ","pages":"Article e00420"},"PeriodicalIF":0.0,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143877358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper investigates how fiscal regulation may influence lower government finances by devolving greater responsibilities to local policymakers that limit free-riding behaviour and ensure fiscal sustainability. To this extent, the Italian case provides a suitable regulatory setting that has evolved over the years, as almost 600 Italian municipalities experienced financial distress from 1989 to 2018. The aim of this study is two-fold: i) to investigate the historical and geographical evolution of local government bankruptcy procedures and ii) to test whether the exogenous Italian legislation on local government defaults influenced the dynamics of the local financial distress phenomenon, identifying three different fiscal regulatory regimes. Our results show that the regulatory regimes until 2000, which prepared for the government bail-out of local defaults, encouraged municipalities to take advantage of the bankruptcy procedures and after 2001, when the legislative interventions had been updated, there is no longer such incentive. Asymmetric effects are observed when municipalities are analysed by population size, pointing to the need to go beyond a one-size-fits-all approach to fiscal policy.

本文研究了财政监管如何通过向地方决策者下放更多责任来影响下级政府的财政，从而限制搭便车行为并确保财政可持续性。在这种情况下，意大利的案例提供了一个合适的监管环境，从 1989 年到 2018 年，近 600 个意大利市政当局经历了财政困难，多年来不断演变。本研究的目的有两个：i) 调查地方政府破产程序的历史和地理演变；ii) 检验意大利关于地方政府违约的外生立法是否影响了地方财政困境现象的动态发展，确定三种不同的财政监管制度。我们的研究结果表明，2000 年之前的监管制度为政府救助地方违约企业做好了准备，鼓励市政当局利用破产程序，而 2001 年之后，随着立法干预措施的更新，这种激励作用不再存在。如果按人口规模对各市进行分析，就会发现不对称效应，这说明在财政政策方面不能采取一刀切的做法。
