Global Shocks Unfolding: Lessons from Fragile and Conflict-affected States
Description: This paper investigates the consequences of global shocks on a sample of low- and lower-middle-income countries with a particular focus on fragile and conflict-affected states (FCS). FCS are a group of countries that display institutional weakness and/or are negatively affected by active conflict, thereby facing challenges in macroeconomic policy management. Examining different global shocks associated with commodity prices, external demand, and financing conditions, this paper establishes that FCS economies are more vulnerable to these shocks compared to non-FCS peers. The higher sensitivity of FCS economies is mainly driven by procyclical fiscal responses, aggravated by the lack of effective spending controls and timely access to financial sources. External financing serves as a source of stability, partially mitigating the adverse impact of global shocks. This paper contributes to a better understanding of how conditions of fragility, which are on the rise in many parts of the world today, can amplify the effects of negative exogenous shocks. Its results highlight the diverse nature of underlying sources of vulnerabilities, spanning from fiscal and external buffers to institutional quality and economic structure, with lessons applicable to a broader set of countries. Efficient and timely external financial support from external partners, including international financial institutions, should help countries’ counter-cyclical responses to mitigate adverse shocks and achieve macroeconomic stability.

The Economics of Decarbonizing Electricity Production
Description: Electricity production is the sector with the largest share of global emissions and there are many options for decarbonizing it. Identifying the lowest cost option for achieving decarbonization (and full reliability) is a complex optimization problem at the intersection of economics and engineering. Key determinants are the cost of individual technologies, the geographical potential, the complementarities between energy sources and supporting infrastructure like electricity grids and energy storage. This paper reviews the literature on the subject and draws high-level conclusions from the abundance of specialized analyses. It finds that energy-economy models have strongly changed projections of the optimal electricity mix in recent years. While the models differ in detail, models project that the share of renewable energy, mostly solar and wind power, increases steadily in a “below 2°C” scenario and becomes the dominant source of energy by 2050. An electricity system based on solar and wind power can use flexibility options as a complement instead of baseload energy. Models vary by the degree to which renewable energy is supported by carbon capture and storage, bioenergy, and nuclear energy.

Measuring Soft Power: A New Global Index
Description: Soft power is difficult to measure directly, and existing indicators—mostly subjective and not always transparent—fail to take into account the multidimensional nature of soft power. In this paper, we introduce a new comprehensive Global Soft Power Index (GSPI) composed of six dimensions for a broad sample of countries over a long span of time. The proposed framework allows for comparisons not only at the “headline” level of the GSPI, but also at the level of the sub-indices, which in turn helps identify and study how countries differ at a granular level of soft power. In a final step of the analysis, we present a possible macro-financial application to investigate the relationship between soft power and exchange rates. The results indicate that some dimensions of the GSPI play an important role in explaining exchange rate volatility. Overall, the composite GSPI presented in this paper provides a systematic approach to measure soft power along its multiple dimensions. By capturing the matrix of soft power characteristics, the GSPI offers significant advantages in comparative analysis of soft power across countries and over time.

Migration into the EU: Stocktaking of Recent Developments and Macroeconomic Implications
Description: Against the backdrop of the war in Ukraine, immigration into the European Union (EU) reached a historical high in 2022 and stayed significantly above pre-pandemic levels in 2023. The recent migration has helped accommodate strong labor demand, with around two-thirds of jobs created between 2019 and 2023 filled by non-EU citizens, while unemployment of EU citizens remained at historical lows. Ukrainian refugees also appear to have been absorbed into the labor market faster than previous waves of refugees in many countries. The stronger-than-expected net migration over 2020-23 into the euro area (of around 2 million workers) is estimated to push up potential output by around 0.5 percent by 2030—slightly less than half the euro area’s annual potential GDP growth at that time—even if immigrants are assumed to be 20 percent less productive than natives. This highlights the important role immigration can play in attenuating the effects of the Europe’s challenging demographic outlook. On the flipside, the large inflow had initial fiscal costs and likely led to some congestion of local public services such as schooling. Policy efforts should thus seek to continue to integrate migrants into the labor force while making sure that the supply of public services and amenities (including at the local level) keeps up with the population increase.

An Updated Action-based Dataset of Fiscal Consolidation
Description: This paper presents a dataset of fiscal consolidation for 17 OECD economies during 1978-2020 and 14 economies in Latin America and the Caribbean during 1989-2020. We focus on discretionary changes in taxes and government spending primarily motivated by a desire to reduce the budget deficit and not by a response to prospective economic conditions. To identify the motivation and budgetary impact of the fiscal policy changes, we examine contemporaneous policy documents, including central bank reports, Convergence Programmes and Stability Programmes submitted by the authorities to the European Commission, and IMF and OECD reports. The resulting series can be used to estimate the macroeconomic effects of fiscal consolidation.

The Economic Impact of Fiscal Policy Uncertainty: Evidence from a New Cross-Country Database
Description: Fiscal policy uncertainty (FPU)—ambiguity in government spending and tax plans, as well as in public debt valuation—is widely regarded as a source of economic and financial disruptions. However, assessing its impact has so far been limited to a few large economies. In this paper, we construct a novel database of news-based fiscal policy uncertainty for 189 countries. Importantly, we track fiscal uncertainty events that generate global attention that we refer to as the “global fiscal policy uncertainty." This uncertainty has contractionary effects, reducing industrial production in both advanced and emerging market economies, with impacts greater than country-specific fiscal policy uncertainty. Additionally, global fiscal policy uncertainty raises sovereign borrowing costs and generates synchronous movements in the global financial variables, even after accounting for US monetary policy shocks.

Transfers, Excess Savings, and Large Fiscal Multipliers
Description: This paper seeks to show that a New Keynesian model can produce highly persistent and large output responses to fiscal transfers and excess wealth, in line with recent empirical literature. The introduction of myopia to households to allow realistic degrees of dissaving from wealth and accumulated transfers, alongside more standard Keynesian features, achieves this goal. Model IRFs closely match the high fiscal multipliers from the tax stimulus SVAR literature, and also have important inflationary consequences. An application of this model to the COVID era, where transfer payments in the United States supported an accumulation of ``excess savings", results in inflation rising by over 1 percentage point for several years as well as a persistent increase in output over the same horizon. Finally, under the same framework and calibration, it is found that high debt and a weak fiscal rule can dull the transmission of monetary policy due to the wealth effect from higher interest payments.

Committing to Grow: The Full Impact of WTO Accessions
Description: This paper studies the impact of the process of accession to the WTO on growth rates in a sample of 150 economies. Unlike GATT-era accessions, WTO accessions involve reforms that extend beyond conventional trade liberalization measures. Using information on the pace of negotiations and requests in the working party's meetings, we construct an index that tracks the progress of reforms in the pre-accession period. We estimate that economies that implemented reforms and made deeper commitments during their WTO accession negotiations grew on average 1.5 percentage points faster than they otherwise would have. These results are robust to instrumental variable estimation and falsification tests.

Mending the Crystal Ball: Enhanced Inflation Forecasts with Machine Learning
Description: Forecasting inflation has become a major challenge for central banks since 2020, due to supply chain disruptions and economic uncertainty post-pandemic. Machine learning models can improve forecasting performance by incorporating a wider range of variables, allowing for non-linear relationships, and focusing on out-of-sample performance. In this paper, we apply machine learning (ML) models to forecast near-term core inflation in Japan post-pandemic. Japan is a challenging case, because inflation had been muted until 2022 and has now risen to a level not seen in four decades. Four machine learning models are applied to a large set of predictors alongside two benchmark models. For 2023, the two penalized regression models systematically outperform the benchmark models, with LASSO providing the most accurate forecast. Useful predictors of inflation post-2022 include household inflation expectations, inbound tourism, exchange rates, and the output gap.

Chinese Banks and Their EMDE Borrowers: Have Their Relationships Changed in Times of Geoeconomic Fragmentation?
Description: While Chinese banks have become the top cross-border lender to EMDEs, their expansion has slowed recently, both in terms of volume and market share. Also, the strong correlation of China’s bilateral trade and its banks’ cross-border lending has weakened, while during 2020-22 lending became more positively correlated with FDI. In our paper, we analyse these patterns and we explore the role of borrower risk variables and foreign policies. Our findings show that, although the shifting correlation from trade to FDI is a general EMDE phenomenon, China’s Belt and Road Initiative reinforces it. By contrast, borrowers that potentially benefit from geoeconomic fragmentation do not display stronger FDI-lending relationships. We also find that Chinese banks exhibit different levels of risk tolerance relative to other bank nationalities as borrower country risk variables are positively correlated with Chinese banks’ market shares, but not with their amounts of cross-border lending.
