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.

Satellite-Based Census of Residential Buildings: Application for Climate Risk Assessment
Description: Housing represents the largest asset and liability, in the form of mortgages, on most national balance sheet. For most households it is their largest investment, and when mortgages are required also represents the largest component of household debt. It is also directly tied to financial markets, both the mortgage market and insurance sector. Although many countries have a rich set of housing censuses and statistics, others have large data gap in this area and therefore struggle to formulate effective policies. This paper proposes an approach to construct a global census of residential buildings using opensource satellite data. Such a layer can be used to assess the extent these buildings are exposed to climate hazards and how their production and consumption, in turn, affect the climate. The approach we propose could be scaled globally, combining existing layers of building footprints, climate and socioeconomic data. It adds to the ongoing effort of compiling spatially explicit and granular climate indicators to better inform policies. As a case study, we compute selected indicators and estimate the extent of residential properties exposure to riverine flood risk for Kenya.

Systemic Implications of Financial Inclusion
Description: This study contributes to the literature by analyzing the impact of financial inclusion (FI) on various bank risk dimensions, including systemic risk, which has been underexplored. We expand on recent research by examining not only the type of financial services, but also the source of FI, particularly the role of non-commercial banks (NCB). Our findings reveal that contrary to developed countries, credit expansions are linked to lower commercial banking risks, underscoring the benefits of loan diversification in developing and emerging economies,. However, while FI in deposits generally reduces individual banking risks, its effect on systemic risk is weaker in these countries, likely due to limited asset diversification. Moreover, NCBs tend to increase systemic and idiosyncratic risks for commercial banks through competitive pressures in the loan and deposit markets. Our results suggest that coordinating macroprudential policies with credit developments further reduces systemic risk by discouraging excessive risk-taking when banks’ capital is more at stake. Banks with stronger Basel capital ratios show reduced idiosyncratic risks, yet there is evidence that banks may relax these ratios to accommodate lending demands. These insights underscore the necessity for regulators to synchronize macroprudential policies with FI developments and consider NCBs’ role in financial stability.

Fiscal Risk Sharing in China: Is It Significant and How to Further Improve It?
Description: The COVID-19 pandemic has weakened the fiscal positions of local governments in China, while the recent stress in the Chinese property market has further compounded this issue, calling for stronger fiscal risk sharing among provinces. This paper examines the existing central to local governmental transfer system and its effect on interprovincial risk sharing and redistribution in China. We show that the fiscal transfers have played an important role in risk sharing although their main purpose is still redistribution. We also propose an alternative transfer mechanism with the size of transfers to each province linked to the shocks that the province is facing to enhance the fiscal risk-sharing effect. Using counterfactual simulations, we show that such an alternative mechanism can significantly enhance risk sharing among all provinces against idiosyncratic shocks while maintaining a comparable level of redistribution effect. Intergovernmental reforms and other structural measures could also be considered to further improve policy efficiency and effectiveness.
