Stack battles: the US-China artificial-intelligence rivalry is moving beyond chips alone
you are currently viewing::Stack battles: the US-China artificial-intelligence rivalry is moving beyond chips aloneJune 22, 2026--China is challenging US leadership in both AI hardware and software, with Europe unlikely to catch up Yet the early evidence suggests that the software gap, like the hardware gap, is no longer fixed or unbridgeable. The signs of Chinese catch-up are real: an open-sourced toolkit with a state-backed contributor pipeline, falling switching costs through PyTorch compatibility, flagship open-weight models running on Ascend and a protected domestic market large enough to sustain the ecosystem through its immature phase. None of these existed in meaningful form two years ago. Source: bruegel.org |
May 29, 2026--Overview
Global manufacturing activity gained some momentum in April and May, supported partly by stockpiling, but services activity remained subdued.
The conflict in the Middle East has increased transport costs and delivery times, with supply chain pressures in April reaching their highest levels since the COVID-19 period.
May 18, 2026-Advancing women's health requires not only scientific progress but an innovation ecosystem capable of translating discovery into evidence, technologies and scalable solutions that improve outcomes for women globally. Yet, despite growing attention, the landscape remains fragmented, and many high-impact conditions continue to receive insufficient targeted innovation.
April 13, 2026--Global imbalances are back in focus. Central banks, international organizations, the G7 and the G20 are debating their causes and remedies. This Paris Report 4-a joint CEPR-Bruegel initiative-aims to provide independent analytical foundations for the debate, particularly for the French G7 presidency. It brings together 17 contributions on global imbalances over the past century, their current configuration among key players (the United States, Europe, and China), and perspectives from lower-income countries.
April 10, 2026-Summary
This paper investigates how the 2025 U.S. trade-policy shocks propagated to global equity valuations. Country-level studies have documented the aggregate costs of tariffs and uncertainty- but firm-level evidence on their joint role after the 2025 shocks remains limited. Filling this gap- we use a firm-level event-study design to disentangle a trade-exposure channel from a sensitivity-to-uncertainty channel.
April 10, 2026-Summary
Payment stablecoins are privately issued digital money with the potential to enhance payment efficiency- foster innovation- and improve financial inclusion. At the same time- they are vulnerable to runs and associated welfare losses. One way to lower run risk is to require stablecoin issuers to hold safe assets. But doing so may lower issuers' profitability and thus their incentive to provide stablecoins- hampering payment innovation and product variety.
April 6, 2026-Summary
Against the backdrop of persistent and recently widening global imbalances, the paper presents a structured framework for understanding how domestic policies can influence current account positions by altering domestic saving and investment decisions. Staff analysis finds that traditional macroeconomic policies remain the dominant drivers of imbalances, but certain types of industrial policies could also play a role.
