The idea of Europe as a community emerged many centuries ago, but its meaning keeps changing—to Europeans and non-Europeans alike. Juliet Johnson has pioneered research on the changing role of European symbols such as the 12-starred flag, designed in the 1950s and formally adopted by European institutions in the 1980s. Intriguingly, shifts in meaning have often first occurred on Europe's eastern side, before being adopted by Europe's western "core."

What does it mean to be European today, in a fast-changing geopolitical environment and amid debates on which new member countries the European Union may incorporate? Can longstanding and newer EU members share similar visions of Europeanness? How do changing identities affect EU policies and market outcomes?

The European Central Bank (ECB) is working on a digital version of the euro, a project started back in 2020 that is coming closer to fruition as the enabling EU legislation progresses. The ECB has designed a digital equivalent of cash, aimed at complementing physical euros for day-to-day payments. Its approach may be compared and contrasted with the US Federal Reserve's reluctance to introduce a digital dollar and with the People's Bank of China's definition of the digital yuan largely as a bank deposit.

Has the ECB's rationale for the digital euro evolved over time, from a response to tech challengers, such as Facebook's Libra project in 2019, towards a more geoeconomic motivation of reducing critical dependency on non-EU payment service providers? What are the main features of the digital euro as currently considered? When will it be concretely introduced, and what are the risks and opportunities in Europe and globally?

European leaders are waking up to the imperative of ensuring the continent's defense in a changed geopolitical environment. But they face complex trade-offs in terms of how to manage the corresponding transition and build the institutions needed for efficient defense procurement, threat assessment, and strategic planning.

Since the 2024 publication of reports by senior statesmen Enrico Letta and Mario Draghi, the European Union has been debating how to improve its competitiveness and foster more high-growth companies. Together with France's Christian Noyer, former German Federal Finance Minister Jörg Kukies has led an in-depth investigation of policy options to that effect. This session discusses their findings and recommendations.

In 2012, Anu Bradford coined the expression "Brussels effect," echoing earlier intra-US references to a similar "California effect"—namely that the global significance of the European market allowed the European Union to shape market regulations worldwide. Is this concept still relevant in a world that appears to have entered a phase of fragmentation?

Ukraine is on a path towards membership in the European Union—subject of course to the outcome of the ongoing brutal war of aggression by Russia. In this inaugural session of PIIE's new Europe-focused live podcast series, we will discuss the challenges and trade-offs both for Ukraine and for the European Union, with a leading government adviser and civil society advocate who was Ukraine's deputy infrastructure minister between July 2022 and October 2024.
