As the world endeavors to decarbonize and shift toward sustainable energy sources, power systems will become increasingly dependent on weather conditions. This dependence creates the challenge of managing fluctuations in both power supply and dema...

Abstract. Recently, the DeepSeek series of models, leveraging their ex-ceptional reasoning capabilities and open-source strategy, is reshapingthe global AI landscape. Despite these advantages, they exhibit signif-icant safety deficiencies. Researc...

: The discussion on Artificial Intelligence (AI) often centers around its impact on productivity, but macroeconomic evidence for Europe remains scarce. Using the Acemoglu (2024) approach we simulate the medium-term impact of AI adoption on total...

US dollar appreciations can inflict sizable negative cross-border spillovers. We investigate such spillovers from flight-to-safety shocks and the accompanying “global dollar cycle”. Results show that negative real sector spillovers from US dollar ...

There are competing narratives about artificial intelligence’s impact on inequality. Some argue AI will exacerbate economic disparities, while others suggest it could reduce inequality by primarily disrupting high-income jobs. Using household micr...

We introduce our first-generation reasoning models, DeepSeek-R1-Zero and DeepSeek-R1.DeepSeek-R1-Zero, a model trained via large-scale reinforcement learning (RL) without super vised fine-tuning (SFT) as a preliminary step, demonstrates remarkable...

This paper takes stock of the literature on infrastructure and jobs published since the early 2000s, using a conceptual framework to identify the key channels through which different types of infrastructure impact jobs. Where relevant, it highligh...

This paper presents a new approach to measuring Global Value Chain (GVC) participation, essential for informed policy-making. It introduces a tripartite classification of GVC involvement—backward, forward, and two-sided— extending beyond trade to ...

Although the feasibility of introducing climate policies underpins global efforts to curb climate change, there has been limited analysis estimating the likelihood of introducing specific policies in different country contexts. Drawing on a datase...
