In this paper, I introduce a New Keynesian - Dynamic Stochastic General Equilibrium (NK-DSGE) model to examine the implications of CBDCs and cryptocurrency in an open economy for emerging markets. In our model, cryptocurrency is implemented as a form of deposit in banks where bankers can also receive deposits from abroad. Lastly, CBDCs are introduced as a payment and saving instrument. I find that cryptocurrency has a crucial role in banking sectors and a significant effect on the dynamic of foreign debt which is highly important for emerging markets. Moreover, I uncover that CBDCs can generate welfare gains but the gain varies with their designs.
在本文中,我引入了一个新凯恩斯主义-动态随机一般均衡(NK-DSGE)模型,以研究cbdc和加密货币在开放经济中对新兴市场的影响。在我们的模型中,加密货币作为银行存款的一种形式实现,银行家也可以从国外接收存款。最后,cbdc作为一种支付和储蓄工具被引入。我发现加密货币在银行业发挥着至关重要的作用,对外债的动态产生了重大影响,这对新兴市场非常重要。此外,我发现cbdc可以产生福利收益,但收益因其设计而异。

The literature has underscored the significance of investor sentiment in understanding excess stock returns and volatility. However, scholars have paid less attention to measuring investor sentiment related to stock markets and analyzing its impacts on the macroeconomy in Vietnam. Our article employs a time-varying parameter structural vector autoregression (TVP-VAR) with stochastic volatility (TVP-VAR-SV) to examine the connectedness of three key variables from January 1, 2017, to November 25, 2023, and to analyze the relationship between investor sentiment and the exchange rate. Following a positive shock in investment sentiment, the exchange rates of USD/VND and GBP/VND exhibited similar responses, showing a negative movement in the 1-period ahead before turning positive in the 3-period ahead. Conversely, EUR/VND and JPY/VND displayed positive movements both in the 1-period and 3-period ahead in response to the shock. Meanwhile, CNY/VND, reacted negatively overall to a positive shock in investment sentiment was negative. Our results have important policy implications for both investors and policymakers. The study also highlights how spillover effects among various indicators and their interconnections can be leveraged to stabilize financial and macroeconomic markets.
这些文献强调了投资者情绪在理解股票超额收益和波动性方面的重要性。然而,学者们很少关注与股票市场相关的投资者情绪的测量和分析其对越南宏观经济的影响。本文采用时变参数结构向量自回归(TVP-VAR)和随机波动率(TVP-VAR- sv)来检验2017年1月1日至2023年11月25日三个关键变量的连通性,并分析投资者情绪与汇率之间的关系。在投资情绪受到积极冲击之后,美元/越南盾和英镑/越南盾的汇率也表现出类似的反应,在未来1个时期内表现为负值,在未来3个时期转为正值。相反,欧元/越南盾和日元/越南盾在前1期和3期均表现出积极走势,以应对冲击。与此同时,人民币/越南盾对投资情绪的积极冲击总体上反应消极。我们的研究结果对投资者和决策者都具有重要的政策意义。该研究还强调了如何利用各种指标之间的溢出效应及其相互联系来稳定金融和宏观经济市场。

The objective of this study is to examine the existence of monetary autonomy within the framework of the macroeconomic trilemma hypothesis. We estimate panel data models with fixed effects, random effects, and fixed effects with cross-sectional dependence to assess monetary autonomy in 36 countries from January 1991 to December 2023. The dependent variable captures changes in policy interest rates in these peripheral countries, while the independent variables include changes in the U.S. policy interest rate, nominal exchange rate regimes (flexible vs fixed or float, soft peg, and peg), capital mobility regimes (capital controls vs free capital mobility or closed, mid-open, and open), foreign exchange reserves relative to nominal GDP, and indicators for currency/financial crises and Covid-19, among others. Using monthly data from various sources, we find no evidence of monetary autonomy under a fixed exchange rate with free capital mobility in both the “corner solution” and “middle ground” models, aligning with the macroeconomic trilemma hypothesis. However, we do find evidence of monetary autonomy in the middle ground case (soft peg with mid-open capital market) and that further evidence that foreign exchange reserves can mitigate the trilemma hypothesis.
本研究的目的是在宏观经济三难假说的框架内考察货币自主权的存在。我们估计了固定效应、随机效应和具有横截面依赖性的固定效应的面板数据模型,以评估 36 个国家从 1991 年 1 月到 2023 年 12 月的货币自主性。因变量捕捉了这些外围国家政策利率的变化,而自变量包括美国政策利率的变化、名义汇率制度(灵活与固定或浮动、软盯住和盯住)、资本流动制度(资本管制与资本自由流动或封闭、中开放和开放)、外汇储备相对于名义 GDP,以及货币/金融危机和 Covid-19 等指标。利用各种来源的月度数据,我们发现在 "角落解决方案 "和 "中间地带 "模型中,都没有证据表明在资本自由流动的固定汇率下存在货币自主性,这与宏观经济三难假说一致。然而,我们确实发现了在 "中间地带 "模型(资本市场开放程度居中的 "软盯住 "模型)下货币自主性的证据,这进一步证明了外汇储备可以缓解三难假说。

This paper investigates the dynamic relationship between fuel price fluctuations and inflation expectations in the Euro Area from 2005 to 2022, employing a Structural Vector Autoregression (SVAR) model to analyze the impact of these price changes on key macroeconomic variables. Focusing on the context of the Russian invasion of Ukraine, this research reveals that fuel price variations significantly influence both short-term and long-term inflation expectations, with the most pronounced effects observed during the initial month of the conflict. However, after March 2022, the impact of fuel price fluctuations on durable and non-durable goods prices diminishes in intensity. These fuel price changes cease to be the primary driver of inflation in the subsequent months, suggesting other factors gain prominence in influencing price levels across the Euro Area. The findings demonstrate that fuel price changes also have economic implications for Eurosystem financial dynamics.
本文研究了2005年至2022年欧元区燃料价格波动与通胀预期之间的动态关系,采用结构向量自回归(SVAR)模型分析了这些价格变化对关键宏观经济变量的影响。着眼于俄罗斯入侵乌克兰的背景,本研究表明,燃料价格变化对短期和长期通胀预期都有显著影响,在冲突的头一个月观察到的影响最为明显。然而,在2022年3月之后,燃料价格波动对耐用品和非耐用品价格的影响程度减弱。在接下来的几个月里,这些燃料价格的变化不再是通货膨胀的主要驱动因素,这表明其他因素在影响整个欧元区的价格水平方面发挥了重要作用。研究结果表明,燃料价格变化对欧元体系金融动态也有经济影响。

We apply the qunatile vector autoregression (QVAR) connectedness and frequency causality methods to investigate tail risk contagion, quantile dependency, and causality linkages among the spot prices of equity, precious metals, and energy commodity markets between 2002 and 2024. Our findings indicate that the average amount of unexpected losses for stock markets is lower than that for other markets. Furthermore, our analysis of tail risk spillovers shows that downside risks are primarily driven by the contributions of others, with the most significant impact occurring when the tail risk is at its lowest. The total downside risks associated with connectedness are greater for lower quantiles and stock markets typically serve as the primary transmitters of shocks across all quantiles. During financial crises, heterogeneous and event-dependent risk spillovers strengthen, but not during pandemics or geopolitical incidents.
我们应用分位数向量自回归(QVAR)连通性和频率因果关系方法来研究2002年至2024年间股票、贵金属和能源商品市场现货价格之间的尾部风险传染、分位数依赖和因果关系。我们的研究结果表明,股票市场的平均意外损失金额低于其他市场。此外,我们对尾部风险溢出的分析表明,下行风险主要是由他人的贡献驱动的,当尾部风险处于最低水平时,影响最为显著。在较低的分位数中,与连通性相关的总体下行风险更大,而股票市场通常是所有分位数冲击的主要传导器。在金融危机期间,异质性和事件依赖的风险溢出效应会增强,但在大流行病或地缘政治事件期间则不会。

This paper examines the impact of transition and physical climate risk on stock markets using, for the first time in this context, the annual Climate Change Performance Index (CCPI) calculated by Germanwatch as well as its components (in addition to a wide range of other indices) for 48 countries from 2007 to 2023. Specifically, a balanced panel VAR model is estimated to obtain impulse responses for the whole set of countries considered as well as for a subset including the EU-28 only; other methods such as Forecast Error Variance Decomposition and Local Projections (Jordà, 2005; 2023) are then applied for robustness checks. The results suggest a positive impact of transition risk on stock returns and a negative one of physical risk, especially in the short term. Further, while physical risk appears to have an immediate impact, transition risk is shown to affect stock markets also over a longer time horizon. Finally, national climate policies seem to be more effective when implemented within a supranational framework as in the case of the EU-28.
本文考察了转型和物理气候风险对股票市场的影响,在此背景下,首次使用德国观察(Germanwatch)计算的年度气候变化绩效指数(CCPI)及其组成部分(除了广泛的其他指数)对48个国家从2007年到2023年进行了分析。具体而言,估计平衡面板VAR模型可以获得所考虑的整套国家以及仅包括欧盟28国在内的子集的脉冲响应;其他方法,如预测误差方差分解和局部预测(约旦,2005;2023)然后应用于稳健性检查。结果表明,转型风险对股票收益的影响为正,而实物风险对股票收益的影响为负,尤其是在短期内。此外,虽然实物风险似乎有直接影响,但转型风险也会在更长的时间范围内影响股市。最后,在欧盟28国这样的超国家框架内实施国家气候政策似乎更为有效。

Macroeconomic effects of climate change: Evidence from Canadian provinces 气候变化的宏观经济影响:来自加拿大各省的证据

We study the long-term macroeconomic effects of climate change across ten Canadian provinces between 1961 and 2017. Following Kahn et al. (2021a), our econometric strategy links deviations of temperature and precipitation (weather) from their multi-decade historical rolling averages (climate) to various province-specific economic performance indicators at the aggregate and sectoral levels. We show that climate change (proxied by a series of weather shocks) has a long-lasting adverse impact on real output in various Canadian provinces and economic sectors. Adaptation reduces the income losses but cannot offset them entirely. Moreover, in contrast to most cross-country results, our within-country estimates suggest asymmetrical growth effects from precipitation and temperature anomalies. Specifically, persistently higher-than-normal precipitation is associated with lower long-term GDP growth, whereas the effect of below-than-normal precipitation is not statistically significant. As regards temperature, while extended periods of cold spells (temperature persistently below historical norms) is detrimental to growth (though less likely in the future), Canada is not benefiting from a warmer climate as often argued in the literature.
我们研究了1961年至2017年间气候变化对加拿大10个省份的长期宏观经济影响。根据Kahn等人(2021a)的研究,我们的计量经济学策略将温度和降水(天气)与其数十年历史滚动平均值(气候)的偏差与总体和部门层面的各种特定省份的经济表现指标联系起来。我们表明,气候变化(以一系列天气冲击为代表)对加拿大各省和经济部门的实际产出产生了长期的不利影响。适应减少了收入损失,但不能完全抵消这些损失。此外,与大多数跨国结果相反,我们的国内估计表明降水和温度异常对增长的影响不对称。具体而言,持续高于正常水平的降水与较低的长期GDP增长有关,而低于正常水平的降水的影响在统计上并不显著。至于温度,虽然长时间的寒冷期(温度持续低于历史标准)对经济增长有害(尽管未来不太可能),但加拿大并没有像文献中经常提到的那样从气候变暖中受益。

What role for aid for trade in (deep) PTA relations? Empirical evidence from gravity model estimations 在(深度)PTA关系中,贸易援助扮演什么角色?来自重力模型估计的经验证据

While preferential trade agreements (PTAs) cover an increasing range of policy areas, little is known about the implications of this new emphasis on interactions with other trade-related policies. We approach this gap by examining the effectiveness of bilateral aid for trade (AfT) in promoting exports for recipient countries within deep North–South PTA relations. Using a structural gravity model for bilateral panel data of 29 OECD DAC countries and 144 developing countries from 2002 to 2015, we find that the marginal effect of AfT decreases as PTA policy areas expand. Further investigation of the underlying mechanisms suggests that the observed trade-off between PTA depth and AfT effectiveness may be due to compliance with the non-tariff provisions contained in deep PTAs. We find two lines of reasoning plausible. First, compliance efforts appear to consume large fractions of AfT, reducing its availability for potentially more effective projects. Second, since we also observe heterogeneity in interactions across donors, AfT provided by high-income PTA partners could well be used to redirect exports to third countries with comparatively fewer bilateral obligations. Provided that a core focus of AfT remains on strengthening international trade relations, including between donors and recipients, donor countries should therefore carefully weigh compliance costs to developing countries against the non-trade benefits of common deep PTAs, and accurately identify financial and technical assistance needs with their PTA partners.
虽然优惠贸易协定涵盖越来越多的政策领域,但对这种新的强调与其他与贸易有关的政策相互作用的影响所知甚少。我们通过审查双边贸易援助(AfT)在深入的南北优惠贸易区关系中促进受援国出口方面的有效性来解决这一差距。利用结构重力模型对29个OECD DAC国家和144个发展中国家2002 - 2015年的双边面板数据进行分析,我们发现AfT的边际效应随着PTA政策领域的扩大而减小。对潜在机制的进一步调查表明,所观察到的优惠贸易区深度与贸易便利化有效性之间的权衡可能是由于遵守了深度优惠贸易区中包含的非关税规定。我们发现有两条推理思路是合理的。首先,法规遵循工作似乎消耗了大量的AfT,降低了其对潜在的更有效的项目的可用性。其次,由于我们也观察到捐助者之间相互作用的异质性,高收入PTA合作伙伴提供的AfT可以很好地用于将出口转向双边义务相对较少的第三国。如果《优惠贸易协定》的核心重点仍然是加强国际贸易关系,包括援助国和受援国之间的贸易关系,那么援助国应仔细权衡发展中国家的遵守成本和共同深层优惠贸易协定的非贸易利益,并准确地确定其优惠贸易协定伙伴的财政和技术援助需要。

Using a structural gravity model for bilateral panel data of 29 OECD DAC countries and 144 developing countries from 2002 to 2015, we find that the marginal effect of AfT decreases as PTA policy areas expand. Further investigation of the underlying mechanisms suggests that the observed trade-off between PTA depth and AfT effectiveness may be due to compliance with the non-tariff provisions contained in deep PTAs. We find two lines of reasoning plausible. First, compliance efforts appear to consume large fractions of AfT, reducing its availability for potentially more effective projects. Second, since we also observe heterogeneity in interactions across donors, AfT provided by high-income PTA partners could well be used to redirect exports to third countries with comparatively fewer bilateral obligations. Provided that a core focus of AfT remains on strengthening international trade relations, including between donors and recipients, donor countries should therefore carefully weigh compliance costs to developing countries against the non-trade benefits of common deep PTAs, and accurately identify financial and technical assistance needs with their PTA partners.</div></div>","PeriodicalId":13794,"journal":{"name":"International Economics","volume":"181 ","pages":"Article 100574"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143148731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the impact of the Belt and Road Initiative (BRI) on consumption risk sharing among participating countries. Utilizing a difference-in-differences model within the context of international consumption risk sharing, we analyze data from 2002 to 2022 for 64 BRI countries. Our empirical findings indicate a significant reduction in consumption risk sharing attributable to the BRI. Further subgroup analysis reveals that the BRI hinders consumption risk sharing particularly among countries along the Land Silk Road, especially those bordering China. Key contributing factors include increased tariffs, heightened foreign investment, rising employment rates, increased resident income, and a diversified range of consumer products. These factors exacerbate the BRI's adverse effects on consumption risk sharing in comparison to countries with lower levels of these variables. Our findings suggest that the Initiative has an uneven impact on the mechanisms affecting countries along its route.
本研究探讨了 "一带一路 "倡议(BRI)对参与国消费风险分担的影响。利用国际消费风险分担背景下的差分模型,我们分析了 64 个 "一带一路 "倡议国家 2002 年至 2022 年的数据。我们的实证研究结果表明,金砖四国的消费风险分担显著减少。进一步的分组分析表明,金砖倡议尤其阻碍了陆上丝绸之路沿线国家,特别是与中国接壤的国家之间的消费风险分担。主要因素包括关税提高、外国投资增加、就业率上升、居民收入增加以及消费品多样化。与这些变量水平较低的国家相比,这些因素加剧了金砖倡议对消费风险分担的不利影响。我们的研究结果表明,金砖倡议对沿线国家的影响机制并不均衡。

Economic freedom and people at risk of poverty in selected Eurozone countries 欧元区部分国家的经济自由度与面临贫困风险的人口

This paper investigates whether higher economic freedom and/or lower government intervention in the economy contribute to poverty reduction. Connecting the percentage of people at risk of poverty with the economic freedom index elaborated by the Fraser Institute, and focusing on 12 Eurozone countries in the period between 2000 and 2019, it appears that both higher economic freedom and a lower level of government intervention in the economy (mostly lower spending in government consumption, investment and transfers and subsidies) are associated with an increase in poverty, which stands in contrast to the predictions of neoliberal economic theory.

本文探讨了较高的经济自由度和/或较低的政府对经济的干预是否有助于减少贫困。将面临贫困风险的人口比例与弗雷泽研究所(Fraser Institute)制定的经济自由度指数联系起来,并以 2000 年至 2019 年期间的 12 个欧元区国家为研究对象,结果显示,较高的经济自由度和较低的政府经济干预水平(主要是较低的政府消费、投资以及转移支付和补贴支出)似乎都与贫困人口的增加有关,这与新自由主义经济理论的预测形成了鲜明对比。
