With the emergence of generative Artificial Intelligence (AI) tools (including large language models) in the popular discourse, the debate on managing, governing, and regulating the impacts of AI on society has grown considerably. In part due to the unique breadth of AI's impacts and its varying...

We construct two new large-scale datasets to measure relative and upward educational mobility by sex, race, class, and childhood county of residence for cohorts born in 1910-1919 and 1982-1997. We show that both relative and upward educational mobility rose over the 20th century, with...

We provide causal evidence that immigration has contributed to the polarization of American politics. Using an ancestry-based shift-share instrument, we study immigration flows into U.S. counties between 1992 and 2016. Counties exposed to larger immigrant inflows become more polarized both in...

Global development policy is a particularly revealing field in which the Trump administration combines crude transactionalism with a high level of ideological commitment, namely an authoritarian libertarianism oriented toward elite interests. This is coupled with, at times, a chaotic absence of...

The higher turnout in Iraq’s recent parliamentary elections reflects advances over the past four years, notably in infrastructure development, security, and political stability. The election’s outcome and ensuing coalition-building dynamics underscore trends and challenges that will shape...

Global development policy is a particularly revealing field in which the Trump administration combines crude transactionalism with a high level of ideological commitment, namely an authoritarian libertarianism oriented toward elite interests. This is coupled with, at times, a chaotic absence of...

Do factual immigration updates shift societal concerns across political ideologies? Conducting an online experiment in the lead-up to the 2024 U.S. Presidential Election, respondents provided local immigrant stock and flow estimates before being randomized to receive realistic information on...

Many instrumental variables applications specify a single Bernoulli treatment. But instruments may change outcomes through multiple pathways or by varying treatment intensity. Lottery instruments that boost charter school enrollment, for instance, may affect outcomes by lengthening time enrolled...

• The 2025 US tariffs are an own goal: American importers and consumers bear nearly the entire cost. Foreign exporters absorb only about 4% of the tariff burden - the remaining 96% is passed through to US buyers. • Using shipment-level data covering over 25 million transactions valued at...

Die Bedeutung des globalen Dienstleistungshandels hat in den letzten Jahren stark zugenommen. So erreichte der Dienstleistungsexport gemessen an den weltweiten Gesamtexporten im Jahr 2023 einen Anteil von über 27 Prozent, in der EU gar von rund 33 Prozent. Gegenüber 2010 ist das global gesehen...

In this paper, we present the empirical methodology used to estimate the Levy Institute Measure of Time and Income Poverty (LIMTIP) for the United States over the period 2007-2022. We provide a step-by-step account of the statistical matching procedure employed to construct a synthetic dataset...

We study the spillovers of large-scale asset purchases (LSAPs) in the U.S. on financial intermediation in the euro area using bank-level supervisory data and high-frequency identified policy surprises. Our detailed panel data permit us to trace the impact of LSAPs through bank balance sheets. We...

Using administrative longitudinal firm- and plant-level data from Mexico that links manufacturing firms to their customs records and covers the period 2014 - 2023, I examine whether US tariffs targeting China have contributed to a manufacturing revival in the southern part of North America....

This paper studies the international macro-financial implications of U.S. dollar-backed payment stablecoins. These digital assets create a new global safe asset channel that links private money creation and global payment needs directly to U.S. public debt. By reshaping the demand for safe...

The prominence of Energy Performance Contracting (EPC) has grown particularly dramatically in recent years, prompting countries to enact policies aimed at fostering wider EPC adoption and backing up the growth of Energy Service Companies (ESCOs). However, the effectiveness of these overarching...

Der vorliegende Bericht untersucht die internationale Verbreitung und strukturelle Ausprägung zweier Schlüsseltechnologien - Künstliche Intelligenz (KI) sowie alternative Antriebe und klimafreundliche Kraftstoffe - auf Basis eines webAI-gestützten Analyseansatzes. Als Datenbasis dient der...

Quality ratings are useful when they capture important and durable aspects of overall performance. They are less useful (and can be misleading) when they are excessively volatile, particularly if volatility is not the result of facility-specific performance. We study the volatility of the...

This paper analyzes heterogeneity in post-pandemic labor market adjustment across industries, contrasting healthcare and social assistance with leisure and hospitality. Using CPS monthly microdata (2015-2023), JOLTS separations, and LEHD Jobto-Job flows, we estimate sector-specific...

We provide initial estimates of the additional weapons and troops Europe will need to defend itself, assuming an effective US withdrawal from Europe. Russia's military production has ramped up: In 2024, Russia produced and refurbished an estimated 1,550 tanks, 5,700 armoured vehicles and 450...

Wir liefern erste Schätzungen über die zusätzlichen Waffen und Truppen, die Europa zur Selbstverteidigung benötigen würde, falls sich die USA aus Europa zurückziehen. Die russische Militärproduktion wurde hochgefahren: Es wurden schätzungsweise 1.550 Panzer, 5.700 gepanzerte Fahrzeuge...

Mit der Wiederwahl von Donald Trump zum US-Präsidenten steht die amerikanische Energie- und Klimapolitik erneut vor einem fundamentalen Einschnitt. Während Trumps Vorgänger Joe Biden mit Investitionsprogrammen wie dem Inflation Reduction Act den klimafreundlichen Umbau der Wirtschaft...

We study how Europe could replace US support for Ukraine both (i) financially, in terms of the fiscal effort required, and (ii) militarily, in terms of weapon production. Financial effort: The financial challenge of replacing US aid is limited. Currently, European governments are spending just...

Europa muss seine Militärausgaben deutlich erhöhen, aber wie? Diese Frage beantworten wir mit einem Blick in die Geschichte. Wie haben Regierungen in der Vergangenheit in ähnlichen Situationen reagiert? Wie wurden Aufrüstung und Kriege typischerweise finanziert - durch Schulden, Steuern oder...

Durch den Ukraine-Krieg und die Entscheidung, auf russisches Pipelinegas zu verzichten, wurde Flüssigerdgas (LNG) zu einem Hauptpfeiler der Energieversorgung Deutschlands und der EU. Die europäische Nachfrage hat die Globalisierung des LNG-Marktes beschleunigt und fördert zugleich...

The United States of America has long been a leading force in international development cooperation, both politically and financially. However, the first weeks of the second Trump administration have called the traditional role of US foreign aid fundamentally into question. From a 90-day funding...

Europe must rapidly increase its military spending, but how? We collect 150 years of data to study what governments in similar situations have done. How were past military buildups financed? What was the relative importance of debt financing, budget cuts, and taxes? Our main finding is that...

US President Donald Trump has recently announced that tariffs on US imports from Canada and Mexico will take effect on March 4, 2025. This policy brief shows that the US tariffs would have a large impact on the North American neighbors. In the event of retaliation, all sectors of the economy...

Job displacement causes large and persistent earnings losses. We document that these losses exhibit a U shape over the life cycle: young and old workers experience greater drops than mid-career workers. We develop a simple search model with human capital accumulation and deterioration that...

Südostasien genießt schon lange außenpolitische Priorität in Japan, doch seit etwa 2012 hat Tokio sein Engagement intensiviert - sowohl gegenüber der ASEAN-Gemeinschaft als auch gegenüber einzelnen Mitgliedstaaten. Tokio betrachtet Chinas wachsenden Einfluss in Südostasien als zentrale...

Apart from several infrastructure projects which ultimately failed, and a surprise visit by the icebreaker Xuelong off the Greenlandic capital, Nuuk, the People's Republic of China has long maintained a cautious and reserved presence in the Arctic in the shadow of Russia and its fleet of...

Der vorliegende Bericht zeigt die Auswirkungen möglicher Zollerhöhungen durch die USA und möglicher Gegenzölle der betroffenen Handelspartner für den Arbeitsmarkt und die Wirtschaft in Deutschland. Die diesem Forschungsbericht zugrunde liegenden Berechnungen basieren auf pauschalen...

The new US administration has a clear agenda of reducing imports to the US and attract FDI by reducing tariffs and using the proceeds for supporting investment in the US. This paper uses a dynamic two country US vs RoW model where monopolistically competitive firms make export and FDI decisions....

This paper investigates how firms navigate the dual challenges of digitalisation and climate change. Our comprehensive approach considers climate change strategies, distinguishing adaptation-only, mitigation-only and 'dual' adaptation and mitigation strategies. Drawing on theoretical insights...
