Rising Temperature, Nuanced Effects: Evidence from Seasonal and Sectoral Data
Description: Using quarterly temperature and sectoral value-added data for a large sample of advanced economies (AEs) and emerging markets and developing economies (EMDEs), this paper uncovers nuanced effects of temperature on economic activity. For EMDEs, hotter spring and summer temperatures reduce growth in real value-added of manufacturing, and most significantly, of agriculture, while a warmer winter boosts it. For advanced countries (AEs), a hotter spring hurts growth in real value-added of all considered sectors: services, manufacturing and agriculture. For both country groups, the negative effect of a hotter spring is larger and more persistent than the positive effect of a warmer winter. Furthermore, the adverse impacts of hotter temperatures in advanced economies have accentuated in recent decades. This result suggests increased vulnerability to rising temperatures.

Navigating Minefields and Headwinds: National Security, Demographic Shifts, Climate Change and Fiscal Policy in Lithuania
Description: Lithuania’s immediate fiscal challenges are national security and higher costs of borrowing, but fiscal prospects are further exacerbated by long-term pressures stemming from climate change and a shrinking and aging population. The country has experienced a rapidly decreasing population—from 3.7 million in 1991 to 2.8 million in 2023—and its old-age dependency ratio is consequently expected to increase from 33 percent in 2023 to 53.4 percent by 2050. The resulting long-term spending pressures are projected to amount to as much as 11.2 percent of GDP, which is about 30 percent of the current level of spending. Debt sustainability concerns would not allow financing additional spending with more debt. Hence, a comprehensive strategy will help address these long-term fiscal challenges, including tax policy changes to raise additional revenue while primarily reducing expenditure needs through pension and healthcare reforms.

Fiscal Discourse and Fiscal Policy
Description: We study the supply of fiscal ideas leveraging thousands of electoral platforms from 65 countries in the Manifesto Project to link how political parties discuss fiscal policy with fiscal outcomes. We provide three sets of results. First, fiscal discourse has become increasingly favourable to higher government spending since at least the 1990s in advanced and emerging economies and across the political spectrum. This pattern does not track survey trends in voter preferences, suggesting that parties have played a role in shifting the focus of political campaigns to fiscal issues to win over voters. Second, fiscal discourse turns conservative under more adverse fiscal conditions, including in the aftermath of debt surges and after the adoption of fiscal rules, but only to a limited extent. Third, over the medium-run, relative discourse changes in favor of government expansion and away from fiscal restraint are followed by higher fiscal deficits. Together, our results suggest that adverse shifts in the supply of fiscal ideas could add to fiscal pressures over time.

The Labor Market Impact of Artificial Intelligence: Evidence from US Regions
Description: This paper empirically investigates the impact of Artificial Intelligence (AI) on employment. Exploiting variation in AI adoption across US commuting zones using a shift-share approach, I find that during 2010-2021, commuting zones with higher AI adoption have experienced a stronger decline in the employment-to-population ratio. Moreover, this negative employment effect is primarily borne by the manufacturing and lowskill services sectors, middle-skill workers, non-STEM occupations, and individuals at the two ends of the age distribution. The adverse impact is also more pronounced on men than women.

Climate Policy Diffusion Across US States
Description: Climate policy at the subnational level is sometimes framed as being counterproductive, because climate change is considered a collective action problem that can be best addressed in a coalition that should be as large as possible. Using comprehensive data from US states on climate policy and policy outcomes, we show that state-level policy is effective in accelerating the adoption of solar energy. Crucially, however, state policies also have positive spillovers to other states, by making it more likely that neighboring states adopt climate policy as well. By proportionally attributing the spillover effects, we find that many US states achieve more climate benefits through the spillovers to other states than within their own jurisdiction. In a further step, we distinguish between climate policies in the energy sector and policies addressed either at other sectors or greenhouse gas emission (GHG) reductions generally. We find that climate policies in the energy sector are distinct from other climate policies in two ways: They have a significant effect on solar capacity growth and they diffuse more broadly.

Beyond the Dikes: Flood Scenarios for Financial Stability Risk Analysis
Description: We assess financial stability risks from floods in the Netherlands using a comprehensive set of flood scenarios considering different factors including geographical regions, flood types, climate conditions, return periods, and adaptation. The estimated damage from each flood scenario is used to calibrate the corresponding macro-financial scenario for bank stress tests. Our results show the importance of considering these heterogeneous factors when conducting physical climate risk stress tests, as the impact of floods on bank capital varies significantly by scenario. We find that climate change amplifies the adverse impact on banks’ capital, but stronger flood defenses in the Netherlands can help mitigate some impacts. Further, we find a non-linear relationship between flood damages and banks’ capital depletion, highlighting the importance of considering extreme scenarios.

A Gravity Model of Geopolitics and Financial Fragmentation
Description: Do geopolitical tensions between countries influence the cross-border asset allocation of investment funds? Our answer is yes. We estimate gravity models and find that investment funds allocate smaller shares of their portfolios to recipient countries that are geopolitically more distant to their country of origin—with geopolitical distance measured by dissimilarity in countries’ voting behavior in the United Nations General Assembly. We also find an investment diversion effect: a recipient country attracts additional investments when its source countries get geopolitically more distant to third-party countries. These results are robust to instrumenting geopolitical distance and using alternative distance measures.

Aggregate Shocks and the Formation of Preferences and Beliefs
Description: A growing body of work has shown that aggregate shocks affect the formation of preferences and beliefs. This article reviews evidence from sociology, social psychology, and economics to assess the relevance of aggregate shocks, whether the period in which they are experienced matters, and whether they alter preferences and beliefs permanently. We review the literature on recessions, inflation experiences, trade shocks, and aggregate non-economic shocks including migrations, wars, terrorist attacks, pandemics, and natural disasters. For each aggregate shock, we discuss the main empirical methodologies, their limitations, and their comparability across studies, outlining possible mechanisms whenever available. A few conclusions emerge consistently across the reviewed papers. First, aggregate shocks impact many preferences and beliefs, including political preferences, risk attitudes, and trust in institutions. Second, the effect of shocks experienced during young adulthood is stronger and longer lasting. Third, negative aggregate economic shocks generally move preferences and beliefs to the right of the political spectrum, while the effects of non-economic adverse shocks are more heterogeneous and depend on the context.

Banking Law and Climate Change: Key Legal Issues
Description: This paper explores the intersection of climate change policies with banking supervisory law. Statutory mandates define banking supervisory agencies’ objectives, functions and powers. Policies that aim to address climate change risks appear fully germane to banking supervisors’ main objective of safety and soundness. As such, banking supervisory agencies have a duty to address climate risks in light of their mandate. A mandate that is not anchored on safety and soundness in light of best practice would blur the accountability of banking supervisory agencies and undermine their legitimacy also with respect to climate. While legal changes can help provide greater legal certaintly, particularly given the long-term perspective of climate change, bank supervisory agencies can take action without fundamental reforms of their legal framework. Accordingly, they have set expectations or requirements for banks to incorporate climate into their strategy and business model, risk management, and governance. A combination of legal instruments—based on soft law and hard law—helps to achieve this objective. Notwithstanding implementation challenges, taxonomies and disclosures remain important tools, and banking supervisors should assess their role in the development of such tools in light of their mandate. The key responsibility to address climate risks rests on banks, and corporate governance frameworks could assist.

Central Banks and Climate Change: Key Legal Issues
Description: Well-designed legal frameworks and institutional arrangments support the legitimacy of central banks’ autonomous decision-making when grounded on sound legal basis and can prevent over-stepping in the remit of other authorities. This paper explores the key legal intersections of climate change and central banks. Climate change could impact price and finanical stability, which are at the core of a central bank’s mandate. While central banks’ legal frameworks can support climate change efforts they also determine the boundaries of the measures they can adopt. Central banks need to assess their mandate and authority under their current legal frameworks when considering measures to contribute to the global response to climate change, while taking actions to fulfill their legal mandates.
