Household Debt and Borrower-Based Measures in Finland: Insights from a Heterogeneous Agent Model
Description: We analyze the effects of borrower-based macroprudential tools in Finland. To evaluate the efficiency of the tools, we construct a heterogeneous agent model in which households endogenously determine their housing size and liquid asset levels under two types of borrowing constraints: (i) a loan-to-value (LTV) limit and (ii) a debt-to-income (DTI) limit. When an unexpected negative income shock hits the economy, we find that a larger and more persistent drop in consumption is observed under the LTV limit compared to the DTI limit. Our results indicate that although DTI caps tend to be unpopular with lower income households because they limit the amount they can borrow, DTI caps are beneficial even on distributional grounds in stabilizing consumption. Specifically, DTI caps mitigate the consumption decline in recessions by restricting high leverage, and thus, they can usefully complement LTV caps.

Fiscal Impacts of Climate Disasters in Emerging Markets and Developing Economies
Description: Climate-induced disasters are causing increasingly frequent and intense economic damages, disproportionally affecting emerging markets and developing economies (EMDEs) relative to advanced economies (AEs). However, the impact of various types of climate shocks on output growth and fiscal positions of EMDEs is not fully understood. This research analyzes the macro-fiscal implications of three common climate disasters (droughts, storms, and floods) using a combination of macroeconomic data and comprehensive ground and satellite disaster indicators spanning the past three decades across 164 countries. Across EMDEs, where agriculture tends to be the principal sector, a drought reduces output growth by 1.4 percentage points and government revenue by 0.7 percent of GDP as it erodes the tax bases of affected countries. Meanwhile, likely reflecting limited fiscal space to respond to a disaster, fiscal expenditure does not increase following a drought. A storm drags output growth in EMDEs, albeit with negligible impact on fiscal revenue, but government expenditure increases due to reconstruction and clean-up efforts. We find only limited impact of localized floods on growth and fiscal positions. In contrast, AEs tend to experience negligible growth and fiscal consequences from climate-induced shocks. As these shocks have much more detrimental effects in EMDEs, international support for disaster preparedness and climate change adaptation play a crucial role for these countries to confront climate change.

The Macroeconomic Effects of Large Immigration Waves
Description: We propose a novel approach to measure the dynamic macroeconomic effects of immigration on the destination country, combining the analysis of episodes of large immigration waves with instrumental variables techniques. We distinguish the impact of immigration shocks in OECD countries from that of refugee immigration in emerging and developing economies. In OECD, large immigration waves raise domestic output and productivity in both the short and the medium term, pointing to significant dynamic gains for the host economy. We find no evidence of negative effects on aggregate employment of the native-born population. In contrast, our analysis of large refugee flows into emerging and developing countries does not find clear evidence of macroeconomic effects on the host country, a conclusion in line with a growing body of evidence that refugee immigrants are at disadvantage compared to other type of immigrants.

How the Brady Plan Delivered on Debt Relief: Lessons and Implications
Description: Rising debt vulnerabilities in low- and middle-income countries have rekindled interest in a Brady Plan-style mechanism to facilitate debt restructurings. To inform this debate, this paper analyzes the impact of the original Brady Plan by comparing macroeconomic outcomes of 10 Brady countries to 40 other emerging markets and developing economies. The paper finds that following the first Brady restructuring in 1990, Brady countries experienced substantial declines in public and external debt burdens and a sharp pick-up in output and productivity growth, anchored by a comparatively strong structural reform effort. The impact of the Brady Plan on overall debt burdens was many times greater than initial face value reductions, indicating the existence of a “Brady multiplier.” Brady restructurings took longer to complete than non-Brady restructurings. Today, similar mechanisms could be helpful in delivering meaningful debt stock reduction when solvency challenges are acute, but Brady-style mechanisms alone would not solve existing challenges in the sovereign debt landscape, including those related to creditor coordination, domestic barriers to economic reforms, and the increased prevalence of domestic debt, among others.

High-Dimensional Covariance Matrix Estimation: Shrinkage Toward a Diagonal Target
Description: This paper proposes a novel shrinkage estimator for high-dimensional covariance matrices by extending the Oracle Approximating Shrinkage (OAS) of Chen et al. (2009) to target the diagonal elements of the sample covariance matrix. We derive the closed-form solution of the shrinkage parameter and show by simulation that, when the diagonal elements of the true covariance matrix exhibit substantial variation, our method reduces the Mean Squared Error, compared with the OAS that targets an average variance. The improvement is larger when the true covariance matrix is sparser. Our method also reduces the Mean Squared Error for the inverse of the covariance matrix.

Optimal Taxation of Inflation
Description: When inflation originates from distributional conflicts, shifts in inflation expectations, or energy price shocks, monetary policy (MP) is a costly stabilization instrument. We show that a tax on inflation policy (TIP), which would require firms to pay a tax proportional to the increase in their prices, would effectively correct externalities in firms’ pricing decisions, tackle excessive inflation and reduce output volatility, without exacerbating price distortions. While proposals from the 1970s saw TIP as a substitute to MP, we find that it is a complement, with TIP addressing markups and inflation expectation shocks, and MP addressing demand shocks.

The Dark Side of the Moon? Fintech and Financial Stability
Description: Rapid advances in digital technology are revolutionizing the financial landscape. The rise of fintech has the potential to make financial systems more efficient and competitive and broaden financial inclusion. With greater technological complexity, however, fintech also poses potential systemic risks. In this paper, I use a novel dataset to trace the development of fintech (excluding cryptocurrencies) and empirically assess its impact on financial stability in a panel of 198 countries over the period 2012–2020. The analysis provides interesting insights into how fintech correlates with financial stability: (i) the impact magnitude and statistical significance of fintech depend on the type of instrument (digital lending vs. digital capital raising); (ii) the overall effect of all fintech instruments together turns out to be negative because of the overwhelming share of digital lending in total, albeit statistically insignificant; and (iii) while digital capital raising is estimated to have a positive effect on financial stability in advanced economies, its effect is negative in developing countries. Fintech is still small compared to traditional institutions, but rapidly expanding in riskier segments of the financial sector and creating new challenges for policymakers.

Lawful Progress: Unveiling the Laws That Reshape Women’s Work Decisions
Description: This paper examines the impact of women’s legal rights on labor force participation decisions made by women and men through a granular analysis of 35 gendered laws. Building on previous literature, it departs from the analysis using aggregate indices due to concerns about (i) the usability of an index for policymaking purposes, (ii) the economic interpretation of an index’s average marginal effects, (iii) and the implicit assumption of homogeneous effects underlying regressions with an index. The findings identify nine key laws that can foster female labor force participation. Notably, laws related to household dynamics and women’s agency within the family, such as divorce and property rights laws, and laws regarding the ability of women to travel outside the home, are especially important in influencing their decision to work. The paper also shows that improving women’s legal rights does not improve their labor force participation through a substitution effect as it has no systematic negative effect on men’s labor force participation.

Monetary Policy Frameworks and Communication in the Caucasus and Central Asia
Description: Central banks in Caucasus and Central Asia (CCA) have been enhancing their monetary policy frameworks in the last decade, and are at different stages of the transition to a type of inflation targeting regimes. This paper documents their progress and the current state of their monetary policy framework, utilizing the IAPOC index developed by Unsal and others (2022) covering Independence and Accountability, Policy and Operational Strategy, and Communications, as well as drawing from central banks’ laws and websites. Additionally, an analysis of press releases from CCA central banks is conducted to evaluate their features, content, and tones. The findings highlight the need for further improvements in the areas of Independence and Accountability, as well as Communications, despite some recent advancements in the latter.

Climate and Cross-Border Migration
Description: Our work is positioned at the intersection of migration and climate change—two key forces shaping the economic outlook of many countries. The analysis explores: (i) the relative importance of origincountry vs destination-country factors in explaining migration patterns; (ii) importance of climate disasters as driver of cross-border migration; and (iii) the importance of climate-driven migration on the overall impact of climate on macroeconomic outcomes. It arrives at the following main findings. First, both origin-country and destination-country contribute to explaining migration outflows from EMDEs, although only the global shocks seem important for advanced economies. Second, climate disasters are important for explaining the origincountry migration shocks in LICs and EMDEs, are especially relevant for smaller countries, and lead to migration of both genders, albeit relatively more for males out of LICs. Third, important portion of climate’s overall impact on economic outcomes—especially agricultural GDP, remittances, and inequality—is captured via climate-driven migration. Finally, higher investment in climate-resilient infrastructure can reduce the impact of climate on cross-border migration, and thereby, result in potentially important economic gains.
