We observe a disquieting problem: the ineffectiveness of conventional monetary policy instruments, including inflation targeting, to deliver price stability in high-inflation environments. We explore two exciting contributions using an intuitive panel data econometric modelling across M1 2010 and M12 2023. First, we highlight the key drivers of inflation in the countries as mostly non-monetary factors–geopolitical risk, fiscal spending, and inflation expectation–to explain why price stability eludes the monetary authorities. Second, we estimate monetary and fiscal policy rules and find that while price stability remains the overarching goal of monetary policy, the fiscal authorities appear unconcerned despite contributing to the problem. We propose a policy coordination strategy that integrates inflation targeting into both monetary and fiscal policy rules, as well as supply-side initiatives.
我们观察到一个令人不安的问题:在高通胀环境下,包括通胀目标制在内的传统货币政策工具在实现价格稳定方面效果不显著。我们使用直观的面板数据计量经济模型在M1 2010和M12 2023中探索了两个令人兴奋的贡献。首先,我们强调了这些国家通胀的主要驱动因素主要是非货币因素——地缘政治风险、财政支出和通胀预期——以解释为什么货币当局无法实现价格稳定。其次,我们估计了货币和财政政策规则,发现虽然价格稳定仍然是货币政策的首要目标,但财政当局似乎并不关心,尽管助长了这个问题。我们建议将通胀目标制纳入货币和财政政策规则以及供给侧举措的政策协调策略。

Will temporary super depreciation allowances for green and digital investments have knock-on effects? 绿色和数字投资的临时超折旧津贴会产生连锁反应吗?

As an incentive towards twin digital and green investment in the corporate landscape, the German Federal Government has suggested a targeted temporary super depreciation allowance to support much-needed green and digital transitions. Using a calibrated multi-sector DSGE model, we find that the temporary super deduction could trigger an uplift of 10 percentage points for crucial green and digital capital spending, turbo-charging decarbonization and digitization ambitions. However, with the temporary corporate tax policy measure set to end after two years, there is a risk that the higher investment expenditures are levelling out afterwards.
为了激励企业在数字化和绿色领域的双重投资,德国联邦政府提出了一项有针对性的临时超级折旧津贴,以支持急需的绿色和数字化转型。使用校准的多部门DSGE模型,我们发现临时超级扣除可能会引发关键的绿色和数字资本支出,涡轮增压脱碳和数字化目标提升10个百分点。然而,由于临时公司税政策措施将在两年后结束,投资支出增加的风险可能会在两年后趋于平稳。

The study assesses the impact of the Covid-19 pandemic on household consumption of alcohol in India, considering both income shocks and supply-side factors. based on a nationally representative household survey conducted by CMIE. Using a 2SLS panel regression model and employing an approach akin to difference-in-differences technique, our study finds that the pandemic induced lockdowns resulted in a sharp increase in the share of alcohol in total expenditure across rural and urban India, and for all income levels. Alcohol consumption varies by education level, by caste, religion, and severity of income shocks. The increased alcohol consumption during the pandemic, and more so among the households that faced a severe income shock, despite the supply restrictions, suggest the stronger impact of stress-response-dampening hypothesis and self-medication hypothesis compared to the income effect. Despite state-imposed supply restrictions, including temporary alcohol shop closures and subsequent reopening with higher taxes, the study raises concerns about a disproportionate rise in alcohol consumption among the most economically impacted. This underscores the need for balanced policy responses, considering both economic stressors and public health imperatives, and emphasizes targeted interventions to mitigate the consequences of increased alcohol consumption during crises.
该研究评估了2019冠状病毒病大流行对印度家庭酒精消费的影响,同时考虑了收入冲击和供给侧因素。基于CMIE在全国进行的具有代表性的住户调查。使用2SLS面板回归模型并采用类似于差异中差异技术的方法,我们的研究发现,大流行导致的封锁导致酒精在印度农村和城市以及所有收入水平的总支出中的份额急剧增加。饮酒量因教育程度、种姓、宗教和收入冲击的严重程度而异。大流行期间酒精消费量的增加,以及尽管有供应限制,但面临严重收入冲击的家庭的酒精消费量增加,表明与收入效应相比,压力反应抑制假说和自我药物治疗假说的影响更大。尽管国家实施了供应限制,包括暂时关闭酒类商店,随后重新开业并征收更高的税,但该研究仍引起了人们对受经济影响最大的酒类消费不成比例增长的担忧。这突出表明需要采取平衡的政策应对措施,同时考虑到经济压力因素和公共卫生需求,并强调有针对性的干预措施,以减轻危机期间酒精消费增加的后果。

Is Pakistan in a debt trap? Do domestic and foreign debts crowd-out private investment? 巴基斯坦陷入债务陷阱了吗?国内和国外债务会排挤私人投资吗?

Historically, Pakistan remained heavily dependent on domestic and external sources of financing which have strangled economic activities. Excessive public borrowing from domestic sources puts upward pressure on interest rates which crowded out domestic investment. Earlier studies found a linear relationship between debt and private investment. However, these studies overlooked the non-linear behavior of debt. The present study fills the research gap by examining the asymmetric impact of domestic and external debt on private investment. Further, this study attempts to explore whether the domestic and foreign debt crowed-in or crowed-out private investment in Pakistan over the period from 1972 to 2022. To this end, the Non-linear Autoregressive Distributed Lag (NARDL) model has been utilized to capture the positive and negative shocks of domestic and foreign debt on private investment. The empirical outcome confirms the existence of both the long-run and short-run asymmetry between private investment, domestic debt, and external debt in Pakistan. Particularly, the positive shock to domestic debt deters private investment, while the negative shock promotes private investment in the short run. On the other hand, a positive shock to foreign debt enhances private investment in the short-run and the opposite holds for the negative shocks in the long-run. Another important finding is the crowding-out effect of public investment on private investment, which holds true in the short run. Thus, there is a need to curtail the size of domestic debt since its accumulation adversely affects private investment.
从历史上看,巴基斯坦仍然严重依赖国内和外部资金来源,这扼杀了经济活动。过多的国内公共借款给利率带来了上行压力,挤掉了国内投资。早期的研究发现,债务和私人投资之间存在线性关系。然而,这些研究忽略了债务的非线性行为。本研究通过考察国内和外部债务对私人投资的不对称影响填补了研究空白。此外,本研究试图探讨在1972年至2022年期间,巴基斯坦的国内和国外债务是否挤占或挤占了私人投资。为此,非线性自回归分布滞后(NARDL)模型被用来捕捉国内和国外债务对私人投资的积极和消极冲击。实证结果证实,巴基斯坦私人投资、国内债务和外债之间存在长期和短期不对称。特别是,对国内债务的正面冲击阻碍了私人投资,而负面冲击在短期内促进了私人投资。另一方面,对外债的积极冲击在短期内促进了私人投资,而对长期的消极冲击则相反。另一个重要的发现是公共投资对私人投资的挤出效应,这在短期内是正确的。因此,有必要缩减国内债务的规模,因为其积累对私人投资产生不利影响。

Market power and fossil fuel subsidy reforms: Who should lead the call for change? 市场力量和化石燃料补贴改革:谁应该带头呼吁变革?

Despite the literature on fossil fuel subsidies broadly supporting a phase-out, the influence of market power on shaping policy outcomes remains uncertain. This is surprising given the influence of OPEC and the presence of economies of scale in the oil sector, which has historically been one of the largest recipients of fossil fuel subsidies. A Computable General Equilibrium (CGE) model that allows for variable endogenous markups and increasing returns is developed to compare the impact of reforms under different market structures. Results show that market power weakens the effectiveness of reforms when implemented by large net exporters such as OPEC, but leads to larger reductions in global oil consumption when carried out by the rest of the world. The article suggests that reforms should be led by net oil-importing and non-OPEC+ countries, rather than attempting to achieve a “UAE consensus” in climate coalitions.
尽管关于化石燃料补贴的文献普遍支持逐步淘汰,但市场力量对形成政策结果的影响仍然不确定。考虑到欧佩克的影响力和石油行业规模经济的存在,这令人惊讶,石油行业历来是化石燃料补贴的最大接受者之一。本文建立了一个可计算一般均衡(CGE)模型,该模型允许可变内生加价和收益递增,以比较不同市场结构下改革的影响。结果表明,市场力量削弱了石油输出国组织(OPEC)等大型净出口国实施改革的有效性,但当世界其他国家实施改革时,市场力量会导致全球石油消费大幅下降。文章建议,改革应由石油净进口国和非欧佩克+国家主导,而不是试图在气候联盟中达成“阿联酋共识”。

Beta and sigma convergence: Are the 15 West African countries catching up with the developed world? 贝塔和西格玛趋同:15个西非国家赶上发达国家了吗?

Studies of economic growth convergence have focused on developed countries with less emphasis on developing countries. We therefore seek to contribute to filling that missing gap by assessing whether the 15 West African countries are converging or catching up with the developed or advanced countries. First, we explored conditional and unconditional beta convergence and secondly, we examined sigma convergence using the mean log deviation and the average GDP per capita relative to the richer USA. We found no evidence of unconditional convergence or sigma convergence between the West African countries and the USA. However, we found evidence of conditional convergence between the two given no variation in structural growth factors. For instance, controlling for investment and population growth, it will take 89 years to cut the gap between the West African countries and the USA into half. Controlling for investment, population growth and human capital accumulation rate, the number of years to cut the gap into half reduces to 78 whereas adding FDI and trade openness increases the speed of convergence to 2 % and reduces the number of years for halving the gap to 35.
经济增长趋同的研究主要集中在发达国家,对发展中国家的关注较少。因此,我们试图通过评估15个西非国家是否正在趋同或赶上发达国家或先进国家来填补这一缺失的差距。首先,我们探讨了条件和无条件贝塔收敛,其次,我们使用相对于较富裕的美国的平均对数偏差和人均GDP来检验西格玛收敛。我们没有发现西非国家和美国之间无条件趋同或sigma趋同的证据。然而,我们发现证据的条件收敛之间的两个给定没有变化的结构性增长因素。例如,在控制投资和人口增长的情况下,西非国家与美国之间的差距需要89年才能缩小一半。在控制投资、人口增长和人力资本积累的情况下,将差距减半所需的年数减少到78年,而增加外国直接投资和贸易开放可将趋同速度提高到2%,将差距减半所需的年数减少到35年。

Investment’s share of government spending in the EU14 Since 1995 – convergence or divergence, and why? 1995年以来欧盟14国投资占政府支出的比例——趋同还是分化,为什么?

With a renewed focus on government investment to address infrastructural, defence and decarbonisation objectives in the EU now arising, the behaviour of its share of government spending across the EU14 countries between 1995 and 2023 is assessed. Greater convergence in that investment ratio has occurred over time, mainly reflecting a decline in periphery member states’ ratios during the 2009–2012 economic crisis. Econometric analysis indicates both cyclical and fiscal variables affecting ratio values, with higher debt ratios associated with relatively lower capital expenditure. With new EU fiscal rules, adopted in April 2024, imposing constraints on government expenditure growth, there is a danger that public capital formation could be constrained relative to identified needs.
随着欧盟重新关注政府投资以解决基础设施、国防和脱碳目标,我们评估了1995年至2023年欧盟14国政府支出份额的行为。随着时间的推移,这一投资比率出现了更大的趋同,主要反映了2009-2012年经济危机期间外围成员国投资比率的下降。计量经济学分析表明,周期性和财政变量都会影响比率值,较高的负债率与相对较低的资本支出相关。随着2024年4月通过的欧盟新财政规则对政府支出增长施加限制,公共资本形成可能相对于已确定的需求受到限制。

The transition to low-carbon energy sources presents critical challenges for competitive electricity markets, particularly in developing economies. This study examines the role of nuclear energy in achieving net-zero targets while addressing market inefficiencies and policy gaps. Using Turkiye as a case study, our findings reveal that nuclear power, despite its low-carbon benefits, faces financial and regulatory barriers that hinder its competitiveness. Through an empirically validated policy model, we propose market-compatible instruments, such as Contracts for Difference (CfD) and capacity remuneration mechanisms, to enhance nuclear investment. These insights offer actionable policy solutions to reconcile nuclear energy deployment with market efficiency.
向低碳能源的过渡给竞争激烈的电力市场带来了严峻的挑战,特别是在发展中经济体。本研究考察了核能在实现净零排放目标、解决市场效率低下和政策缺口方面的作用。以土耳其为例,我们的研究结果表明,尽管核能具有低碳效益,但它面临着阻碍其竞争力的金融和监管障碍。通过经验验证的政策模型,我们提出了与市场兼容的工具,如差价合约(CfD)和能力薪酬机制,以促进核能投资。这些见解为调和核能部署与市场效率提供了可行的政策解决方案。

North America (Canada, US, Mexico) is a highly inter-connected regional economy (ICRE) with extensive cross-country value chains in production and strong trade, financial, and labor market links. The impact of new US deportation policy would affect the US economy in the short to medium term by reducing the labor force by nearly five percent as foreign-born labor leaves the country or drops out of the labor market. Analysis with a global computable general equilibrium (CGE) simulation model indicates that the shock would cause a supply-side recession in the US and reduce real GDP by four percent. The wage in the labor markets with high participation of the remaining undocumented labor would increase, which would provide an incentive for increased future migration. There would also be a decline in the wage of native-born workers; studies indicate that they are complements not substitutes for non-native labor in their sectors of employment. The US macro shock would also induce macro shocks to both Mexico and Canada, yielding reductions in their GDP. In addition, there would be a dramatic decline in remittance flows from foreign-born workers to their countries of origin. For Mexico, the reduction in remittances would lead to a financial shock due to lost foreign exchange, resulting in a major depreciation of the real exchange rate and changes in macro aggregates: lower GDP, lower imports, increased exports, and much lower aggregate final demand. The financial shock in Mexico would feed back to Canada and the US, affecting the sectoral composition of trade and production in both countries. In sum, the impact of US policies to remove foreign-born labor would reverberate across all three countries, damaging their economies and weakening economic integration in North America.
北美(加拿大、美国、墨西哥)是一个高度互联的区域经济体(ICRE),拥有广泛的跨国生产价值链和强大的贸易、金融和劳动力市场联系。美国新驱逐政策的影响将在中短期内影响美国经济,由于外国出生的劳动力离开美国或退出劳动力市场,美国劳动力将减少近5%。利用全球可计算一般均衡(CGE)模拟模型进行的分析表明,这种冲击将导致美国的供给侧衰退,并使实际GDP减少4%。剩余无证劳工高参与的劳动力市场的工资将会增加,这将为未来增加的移民提供激励。本土出生工人的工资也会下降;研究表明,他们在其就业部门是对非本国劳动力的补充,而不是替代。美国的宏观冲击也会引发墨西哥和加拿大的宏观冲击,导致两国GDP下降。此外,外国出生的工人汇回原籍国的汇款也将急剧减少。对墨西哥来说,汇款减少将导致外汇损失造成的金融冲击,导致实际汇率大幅贬值和宏观总量的变化:GDP下降,进口减少,出口增加,最终总需求大幅下降。墨西哥的金融冲击将反馈到加拿大和美国,影响两国贸易和生产的部门构成。总而言之,美国消除外国出生劳动力的政策将对这三个国家产生影响,损害它们的经济,削弱北美的经济一体化。
