Abstract:
Measurement errors in macroeconomic aggregates such as GDP have been widely lamented, particularly in low-income contexts. This study investigates the reliability of one component of national accounts, agricultural sector output. Focusing first on the case of Mozambique, we use a series of 12 harmonized national agricultural micro-surveys to construct estimates of gross annual output in the sector. Compared to corresponding national accounts values for the period 2002–20, the micro-survey estimates are about 50% lower. A decomposition exercise indicates this gap is primarily driven by differences in base year levels, offset by higher rates of inflation observed in survey-based producer prices. Triangulating these estimates using household budget surveys, market price, and FAO production data, we find consistent support for the agricultural micro-survey estimates, suggesting real rates of total GDP growth may have been overestimated by 1 percentage point over the period. A cross-country comparison of national accounts and FAO production data indicates positive differences between estimates of agricultural output from the two sources are not unique to Mozambique, but with larger discrepancies among lower-income countries. Systematic investment in reliable and timely agricultural statistics is essential to track progress in the sector.

2. Are bad governments a threat to sovereign defaults? The effects of political risk on debt sustainability

Abstract:
Political risk is a significant determinant of bond yields and economic growth in both developed and emerging markets and we develop a debt sustainability analysis model with both channels using a country ratings proxy of political risk. Political risk also affects a sovereign’s willingness to pay and it can render debt unsustainable, triggered by changes in the rating level, volatility or both. Conversely, sustainability can be restored through reforms that can be as effective as large-scale quantitative easing programmes. The political effects on debt are especially large for high-debt countries during periods of high interest rates, and have an impact on debt management through the choice of optimal financing maturities.

3. Gender diversity and economic growth

Abstract:
Most macroeconomic and growth accounting models assume that male and female workers are perfectly substitutable in the aggregate production function. Whether this assumption is valid is an empirical question that this paper aims to answer by estimating the elasticity of substitution between female and male labour. We apply linear and non-linear techniques to firm-level data, cross-country sectoral data and cross-country aggregate data. We find that women and men are far from being perfect substitutes in production, a result that is consistent with much microeconomic evidence, but has not permeated to macroeconomics. The failure to account for imperfect gender substitutability has far-reaching implications. In particular, standard growth accounting exercises are likely to attribute to technological progress gains that are more properly attributable to the impact of greater gender inclusiveness in the labour force over time. Put differently, the gains from gender inclusiveness are likely to be much larger than standard economic models estimate.

4. Lessons for the European Central Bank from the 2021-2023 inflationary episode

Working Paper
Institution:

Abstract:
Since mid-2021, the euro-area economy has gone through several shocks, leading to the highest inflation since the creation of the European Monetary Union. A forceful and persistent response from the European Central Bank, grounded in the monetary policy framework it agreed in 2021 ahead of the inflationary episode, has succeeded in bringing inflation down and delivering on the central bank’s price-stability mandate. The framework will be reviewed in 2025 and it might conclude that there is no need for a drastic change. Nevertheless, this assessment should be compatible with identifying some areas for improvement. In particular, the 2021 review was primarily focused on the effective lower bound. The recent inflationary episode, together with high ongoing uncertainty, indicate that the articulation of monetary policy strategy frameworks should be robust to very different scenarios. Likely persistence of high levels of uncertainty over the next few years will also require an emphasis on flexibility to adapt to the magnitude, origin and persistence of shocks. Unconditional forward guidance should be avoided. In addition, there might be a need to more clearly distinguish in the future, when possible, between quantitative easing for market functioning versus monetary stimulus, which could incentivise a careful assessment of the amount, duration and structure of any asset purchase programme. Communication also needs to be improved in relation to the level of uncertainty and its consequences for monetary policy making with, for instance, greater use of scenarios and sensitivity analyses as appropriate. Improving forecasting/modelling tools, in particular when dealing with large supply shocks, and understanding the roles of different measures of inflation expectations should also be priorities.

5. Sovereigns on thinning ice: debt sustainability, climate impacts and adaptation

Abstract:
A fundamental problem for sovereigns enacting climate policies is whether they can manage increasing debts as their economies suffer from adverse climate impacts. We develop stochastic debt sustainability analysis integrating a coupled climate-economy model with debt financing scenario optimisation, and stress test sovereign debt for representative countries globally under the Intergovernmental Panel on Climate Change marker narrative scenarios of climate change. The stress test combines socioeconomic and climate pathways with calibrated aleatory scenario trees of economic, fiscal and financial variables to generate forward-looking debt projections over the century. These projections incorporate climate-induced damages to economic growth, spanning the broad spectrum of impact functions from the literature. Our findings reveal significant risks to sovereign debt sustainability, particularly under high climate damages, that are large from mid-century. Expected costs increase by up to 3 percent of GDP under high climate impact in a world of regional rivalries, or 0.25 percent under low impact in a middle-of-the-road narrative, with considerable variation between countries. The long-run debts of highly impacted countries are unsustainable. We assess whether adaptation investments or fiscal consolidation can mitigate potential climate-debt crises. Public financing of reactive adaptation is a justified expenditure that breaks even but does not fully restore the debt sustainability of highly impacted high-debt countries. Maintaining public spending while ensuring debt sustainability appears infeasible under climate impacts.

Abstract:
In the context of the push by the European Union for regional integration in the Western Balkans, this paper explores the barriers to, and prospects for, deeper intra-Western Balkan economic relationships. First, it addresses the pronounced bilateral economic relationships between Western Balkan countries associated with historical path-dependencies. Second, by comparing the Central European Free Trade Agreement with Stabilisation and Association Agreements that the EU has with Western Balkan countries, it identifies areas of less economic integration under the former. Third, it focuses on intra-Western Balkan trade barriers and how the associated costs influence regional integration. Finally, the paper describes the structures of Western Balkan economies and how much they contribute to regional exports through domestic value added. The paper emphasises the importance of regulatory alignment for reducing trade barriers and the role of funds under the EU Growth Plan for the Western Balkans for investment in transport infrastructure within the region. It finds that the Central European Free Trade Agreement and Common Regional Market should focus on untapped potential, especially in the liberalisation of capital, services and movement for employment. Infrastructure issues, trade logistics and the tackling of technical barriers to trade should feature prominently on the policy agenda.

7. European export finance needs a reboot

Abstract:
Export credit agencies (ECAs) play an important role in international trade by providing derisking instruments that function as public assistance to companies engaging in international commerce. As the geopolitical environment has become more fraught, this support has become ever more important. In recent years, the role of ECAs has evolved from a purely commercial one to include the pursuit of strategic goals, such as fighting climate change, shaping trade relations with key partners and securing access to critical raw materials. However, the system of European export credit agencies is not well equipped to deal with these challenges. ECAs are national with a variety of models and not all European Union countries have one. There is little transparency on their operations, very limited steering at the EU level and, beyond a small pilot project in Ukraine, no EU-level funding for European public goods. Non-EU ECAs have increasingly used funding instruments not available to EU ones, partly because of competition from countries not subject to the OECD Arrangement on Officially Supported Export Credits and state aid constraints. This makes the lack of coordination not only a strategic oversight but a potential competitive disadvantage. For these reasons, we argue that reform of the European ECA sector is necessary. We advocate for improved transparency and EU-level steering to ensure European strategic objectives are met. More complex is the question of how European public goods could be adequately supported by ECAs. Several models are possible, with the most promising option being EU level funding for projects implemented by national ECAs coupled with some form of EU level oversight.

8. How can Europe’s nuclear deterrence trilemma be resolved?

Abstract:
The United States under President Donald Trump has adopted an ambiguous position on European security. Although no immediate risk of abandonment is apparent, European countries are rethinking their defence strategies in case the US declines to support them, or provides only partial support, in a crisis. This discussion is particularly sensitive in relation to nuclear weapons, the ultimate deterrent, for which European countries depend extensively on the United States. We argue that a possible future US withdrawal from European nuclear security will force European countries to face a policy trilemma. If they stick to the existing policy framework of no proliferation and no joint deterrence, they expose themselves to nuclear blackmail, should the US withdraw its external guarantee. If they want to protect themselves from nuclear blackmail, they must choose how to provide nuclear security: either collective nuclear security, which would compromise some national sovereignty, or independent provision by individual countries, leading to nuclear proliferation in Europe. Having established that uncontrolled proliferation is an inferior outcome to some form of joint deterrence, we identify four main alternatives: an extension of the Franco-British nuclear deterrent; an extension complemented by a jointly financed expansion of existing deterrence; the absorption of the French (and perhaps British) nuclear arsenals into a European arsenal; and the construction of a separate European submarine deterrent (with Europe using French or British technology or developing new technology). We also discuss briefly forms of non-nuclear deterrence, which however would likely be a complementary rather than a substitute for a nuclear deterrent. We compare these options using a set of parameters: strategic autonomy and credibility, changes to treaties (including non-proliferation), costs, capabilities and readiness. Our analysis shows that all options have advantages and disadvantages, but some are politically, financially and militarily more feasible.

9. Prepare now: Europe must get ready for the coming long-term care surge

Abstract:
Demographic change and ageing populations in European Union countries will impact many aspects of the economy and have a direct effect on long-term care (LTC) systems. Demand for LTC already exceeds supply in many EU countries, leading to the ‘care gap’. This gap is expected to widen, threatening quality of life for the elderly, exacerbating gender disparities and imposing significant economic costs. The root causes of the gap include demographic shifts, inadequate public investment, workforce shortages and a heavy reliance on informal caregiving. Women stand to lose the most if no steps are taken to prepare LTC systems for the coming surge in demand because care, both formal and informal, is predominantly provided by women. The care gap can be reduced by either increasing the supply of care or by reducing the demand for care. We assess LTC reforms in five EU countries and explain how these can affect the care gap by influencing demand and supply. Governments should: Recognise LTC as a priority. Governments should increase public spending on LTC and make LTC a central policy priority linked to broader goals, including gender equality and economic growth. Expand funding mechanisms. Governments can introduce new means of financing, such as mandatory LTC insurance and pre-funding mechanisms. Most importantly, benefits should target those with the greatest needs, to promote equity and adequacy. Support the workforce more. The LTC sector should be made more attractive by raising wages, improving working conditions and expanding training programmes to attract and retain workers. Develop prevention strategies. EU funds could be directed to research into treatments targeting age-related diseases such as dementia. National governments could invest in public health campaigns and preventive care to reduce future demand. Use the newest technologies. EU countries should invest in robotics and assistive technologies to improve productivity and to reduce physical strain on caregivers.

10. How to improve the European Union’s sustainable finance framework

Policy Brief

Abstract:
The European Union has sought to steer corporate behaviour to support its climate goals by adopting a large body of rules on sustainable investment, sustainability disclosures and sustainability labelling of financial products, underpinned by a taxonomy of activities considered sustainable. It is unclear, however, if this effort has had significant results. Examination of financial market data and metrics of investment flows towards green and sustainable investment shows up several weaknesses – both contingent and structural – in the EU sustainable finance framework, which could limit its effectiveness in aligning capital flows with climate objectives. The Sustainable Finance Disclosure Regulation (SFDR) is aimed at making the sustainability content of financial products more transparent but rests on a concept of ‘sustainable investment’ that is too broad and loosely defined. Meanwhile, the EU Taxonomy Regulation has not yet become established as the reference framework for corporate bond issuance or sustainable investing. The EU also lacks a coherent framework for transition finance – or investment that is not yet classified as sustainable but that represents progress to greater sustainability – despite this being the market segment to which the largest volumes of investment will need to flow in the short to medium run. Five adjustments would make the EU sustainable finance framework more effective at delivering the desired alignment of incentives. First, the taxonomy framework should be completed and clarified. Second, the SFDR definition of sustainable investment should be toughened. Third, the neutrality of the framework across capital market instruments, in particular debt versus equity, should be ensured. Fourth, a dedicated framework for transition finance should be developed. Finally, formal sustainable and transition labels for financial products should be introduced. This approach would make the sustainable finance framework more easily applicable to all kind of companies and all types of capital market instruments, regardless of whether they limit the use of proceeds, and it would be naturally extendable into a framework for transition finance and into a transparent sustainability labelling regime for financial products.
